THERMALSTATICALLY STEERED MIXING VALVE

The invention refers to a thermalstatic mixing valve for cold and warm water, thermalstatic NIischventile with intake valves for cold and warm water is well-known, whereby each valve exhibits a diaphragm, which locks a counter-pressure chamber lying behind, which is fed upstream by the valve. The counter-pressure chambers are provided with the cross section variable s discharge channels, which are steered opposite by a thermalstatic Vertefler. With a well-known execution form of this kind the thermalstatic distributor exhibits a bimetallic strip, which shifts in the area between a nozzle for cold water and a nozzle for warm water, whereby the nozzles at the ends of the discharge channels of the counter-pressure chambers lain downstream are arranged. The Bimetailstreifen forms an adjustable catch for the RST and the other nozzle and the discharge of the water mixture by a manual control is closed off, which brings the two nozzles closer each other. One of the nozzles is stationary, while the other nozzle is adjustably arranged. Between the two nozzles and by these the bimetallic strip and the nozzles are enclosed are at the same time closed. With this well-known mixing valve is the shut-off control for landing on water Rome with thermostatiis schen control connected and when closing the flow direction off the temperature of the effluent water mixture is adjusted. It is task of the invention to create a water supply device whose thermalstatic mixing valve is improved and simultaneous closing of the two intake valves guarantees by increase of the pressure in the area back buntings” without the temperature attitude of the water mixture understands and one changes. This task is permitted by a mixing valve solved, with which a shutoff device independent of the thermalstatic distributor is intended, one interrupting the water river in the discharge channels upstream the distributor, in order to make the gieichzeidge closing possible of the two intake valves without participation of the thermalstatic distributor. Furthermore with a preferential execution form a release device is intended, which is so laid out with pressure or temporally steered and that it operates automatically the shutoff device of the mixing valve, either after reaching a certain level of the water in a container, for example a bath tub, or after a certain work time. The thermostatisehe Mischventll according to invention, which is vervoliständigt by different control devices, makes an automatic closing of the water river off, if a bath tub or any other container with a certain, before for adjusted quantity of water possible filled and a certain water level is reached, whereby the temperature of the bath water is adjustable and perfectly independent of the shut-off level. The invention ird on the basis a remark example represented in the designs more near 3s describes. Fig.1 a diagram of the Mischventilso that shows the way of the cold water illustrated, whereby the lower part represents one cut-respectably along the line 1-1 in Fig.4 and the top an axial cutaway view; Fig.2 one the Fig.1 similar opinion, which illustrates the way of the warm water, whereby the lower part is a cutaway view along the line 2-2 in Fig.4 and the top an axial cutaway view, however in another working position than in Fig.1; Fig.3 a front view of a part lVäschventils on average, along the line 3-3 in Fig.2; Fig.4 a back opinion of a part of the Mischventlls toward the arrow G seen and partly on average along the line 4-4 in Fig. 1; Fig.5 an increased detail opinion of the thermalstatic distributor; Fig.6 and 7 cutaway views along the line 6-6 and/or 7-7 in Fig.5; Fig.8 an increased cutaway view of the shutoff device, essentially along the line 8-8 in Fig.2, whereby two pins of the shutoff device are shown in different work divisions; Fig.9 a cutaway view of an indicator for the water level of the water let in into a bath tub; and Fig.10 one the Fig.9 similar opinion, which illustrates an amended execution form. The mixing valve according to invention consists of a housing --1--, the one connecting piece --F-- (Fig.4) for the inlet, that exhibits over one with a filter --3-- and a one-way valve --4-- so provided line --2-- with an internal connecting piece --5-- is connected (Fig.1). The end of the connecting piece --5-- forms the seat for an intake valve --A-- for ka1 tes water, that from the central range of a diaphragm --6-- , their extent exists under a ring --7-- is wedged. Behind the diaphragm --6-- and a counter-pressure chamber is limited by this --8-- planned. By this counter-pressure chamber --8-- a nozzle leads --9-- with small cross section, which guarantees the inlet to this chamber. In Fig.1 is the Einlaßventll --A-- shown in open position, so that the connection by the holes of the ring --7-- between the connecting piece fed with cold water --5-- and a mixing chamber --10-- is manufactured. This mixing chamber is with a discharge opening --M-- provide for the water mixture, which is attached for example under inserting a reversal lever for a shower at a bath tub armature. If the pressure in the counter-pressure chamber --8-- , shifts the diaphragm rises --6-- to the right (Fig.1), whereby the intake valve --A-- for cold water one closes. A feather/spring --11-- works when closing this intake valve --A-- with. The water can from the counter-pressure chamber --8-- run out by a discharge channel. This discharge channel consists of a line lain upstream --12-- and a line lain downstream --13--, between those a shutoff device --P-- is arranged (Fig.1). The line lain downstream --13-- communicated over a thermalstatically steered Vertefler adjustable in the cross section --D-- (Fig.5 to 7) with the mixing chamber --10--. In this Vertefler --D-- the line flows --13-- into a cavity --14-- a stationary axle --15--, around a I= the mobile part --16-- , its angle position turns by a bimetal switching element --17-- , that is certain in the mixing chamber --10-- is arranged. The part --16-- turns toward the arrow Z (Fig.6) around the axle --15--, if the temperature of the water mixture in the mixing chamber --10-- rises. Thus an opening becomes --18-- increased, so that the counter-pressure chamber can be emptied then faster. The same meets for the more pronounced opening of the intake valve --A-- for cold water too. A circulation of the hot water (Fig.2) is in the same way laid out like the circulation of the cold water. The appropriate construction units of the warm water circle point the same however also --20-- increased reference symbols up like the construction units of the chilled water circle. The warm water circle begins with an inlet connecting piece --C-- for warm water (Fig.4), that with an intake valve --B-- for warm water 2, that is provided the inlet of the warm water into the mixing chamber --10-- adjusted. In the warm water circle is the shutoff device --P-- between a line lain upstream --32-- and a line lain downstream --33-- arranged, whereby the line into a cavity, lain downstream --34-- the axle --15-- , their opening flows --38-- is narrowed, if itself the mobile part --16-- toward the arrow Z (Fig.6) turns. The cross sections of the discharge openings --18 and 38-- become in this way by the shift of the part --16-- in the opposite sense it changes, in such a manner that when opening the intake valve --A-- for cold water the intake valve --B-- for warm water closes and in reverse. The position of the Bimetallschaltglledes --17-- can with the help of a button --20-- are changed, that with an attack --21-- cooperates, in order according to desire the temperature of the water mixture to adjust (Fig.1). The Absperrvorrlchtung --P-- consists of one at a cover --41-- the housing --1-- fastened block --40--” in that two movable pins --42 and 43-- assigned, those are actuated with a common transverse bar --44-- are connected (Fig.8). The pins --42 and 43-- are in drillings of the block --40-- been, in those intermediate chambers --45 and 46-- and Endkammern --47 and 48-- are intended. Into the intermediate chambers --45 and 46-- flow the lines --12 and 32-- and into the Endkammern --47 and 48-- flow the lines --13 and/or 33--. Ring seals --49 and 51-- limit the chambers and serve as seats for the pins. According to the position of the transverse bar --44-- can the pins --42 and 43-- with the seals --49 and/or 51-- cooperate. In the closing position shown in Fig.8 left interrupts with the poetry --49-- cooperating pin --42-- each connection between the appropriate 4s upstream and downstream convenient lines --12, 13--. In the open position shown in Fig.8 right is the pin --43-- in the distance from the poetry --51--, in such a manner that the connection between that upstream and downstream convenient lines --32, 33-- is open. The transverse bar --44-- is in a movable construction unit laid out as frameworks --52-- arranged, that from two upright-standing carriers --53-- and an upper transverse bar --54-- exists. This upper transverse bar --54-- a recess points --55-- up, in the one centric arm --56-- a rocker arm --57-- is assigned (Fig.2). The rocker arm --57-- is around an axle --58-- between two outermost angle positions tiltable stored, which are perspectively shown in the Fig.1 and 2. In these positions is the arm --56-- downward and/or upward bent and holds the frameworks --52-- in the open and/or closed position of the pins --42 and/or 43--. The rocker arm --57-- becomes by a feather/spring --59-- in or others of the two positions strained. The feather/spring --59-- the form of an open O (omega) has and is between a handle --60-- the tilting elevation ice --57-- and an attack --61-- begun. The attack --61-- is at the end of a supporting rail --62-- arranged, those for their part at the end of a post --63-- , that sits by a screw --64-- at the block --40-- is fastened (Fig.2 and 3). The supporting rail --62-- lateral parallel flanges point --65-- on (Fig.3), those with recesses --66-- (Fig.1), in those the ends of the axle are provided --58-- the rocker arm --57-- are assigned. By further recesses --67-- in the flanges --65-- is the transverse bar --54-- put and ¢hue between the flanges --65-- arranged bridge --68-- serves for take up a screw --69--, at that adjustably a three-lateral handle or a forked Stangenverbindung --70-- is adjustably led. A feather/spring --71-- stretches the handle --70-- in the position shown, in more äer it at the head --72-- the screw --69-- lies close (Fig.1). The handle --70-- is üssig kraftsch] with a pushbutton --73-- connected and its thighs --74 and 75-- work with the lateral attacks --76 and 88-- the rocker arm --57-- together, if it by pressing the pushbutton in --73-- Is shifted (Fig. 1 and 3). By the manipulation of the handle --70-- with the help of the pushbutton --73-- becomes the rocker arm --57-- from the outside position into the other one moves, whereby it by the feather/spring --59-- strained and by these one leads and one holds in position. A pressure-dependent Auslösevorrichmng --78-- operates the shutoff device --P--, as soon as the water level in the bath tub a bestlrùmtes reached level. This Auslösevorrichmng --78-- consists of a diaphragm --80--, for example from rubber, those in a rigid covering and/or flatten bowl --81-- is assigned. The edge --82-- the diaphragm --80-- a sealed chamber is gotten jammed, in such a manner under the edge of the bowl, --84-- one includes. Into this chamber --84-- a line flows --86--, those of a level indicator --87-- (Fig.9) goes out. The diaphragm --80-- is with a plate --88-- provided, those as edition for an end --89-- a lever --91-- serves, --92-- is linked. The other end --93-- the lever --91-- a Blatffeder points --94-- with nose --95-- up, those with the rocker arm --57-- (Fig.1 and 2) co-operate. One around a screw mounting --97-- a button --98-- arranged feather/spring --96-- practices over an attack --99-- an adjustable counter acting force on the lever --91-- out. If the pressure in the chamber --84-- , takes the lever is weak --91-- in Fig.1 the shown on position, in that the nose --95-- behind a bar --101-- the rocker arm --57-- is seized. If the pressure in this K-more rainer --84-- it becomes so large that it the lever --91-- against the effect of the feather/spring --96-- to shift, moves diesr lever can into the position shown in Fig.2, whereby the nose --95-- at the same time the rocker arm --57-- into its different one, in. Fig.2 represented, angle position shifts. The level indicator --87-- (Fig.9) becomes at the discharge opening --103-- a bath tub --102-- installed. The discharge opening is with a poetry --104-- provided and with a rust --105-- covered. With the ground of the bath tub is a shopkeeper --106-- over a line --107-- connected. Of the KArùrùer --106-- a line furthermore leads --86-- into the chamber --84-- the pressure-dependent release device --78--. The water level, which is easily changeable, becomes in the KArùrùer --106-- specified, beispielsweie at height of the line --I08--. The lower range care --106-- therefore fills with water, as the water level in the bath tub the appropriate height reached. The attempt shows that the positive pressure of air regarding the atmospheric pressure in the chamber --106-- and the air line --86-- proportional it is the water level in the bath tub, in such a manner that the shutoff device can automatically interrupt the Wasserzulauf and with it a filling of the bath tub, as soon as the desired water level is reached. The height of this water level can according to desire with the button --98-- are adjusted. If the discharge opening --103-- , runs the entire water from the chamber is opened --106-- and the line --107-- by the discharge pipe --109-- the bath tub off. With an amended execution form (Fig.10) the chamber can --106-- also by in a side panel --112-- the bath tub, close of its ground arranged connecting piece --111-- attached so its. In other cases, in particular with manipulation of a shower, it can be also desired to turn the inlet off of the water automatically after a certain time interval. For this reason the mixing valve according to invention is also with a temporally steered shut-off performing --114-- provided (Fig.2). This temporally steered shutoff device --114-- works likewise with the lever --91-- together. It consists those of a time switch of any well-known design, in a housing --115-- is assigned and with a bent cam --116-- , that cooperates for his part an end of the lever --91-- is assigned and these after one by an adjusting lever --117-- adjustable time interval operates. The mixing valve according to invention works as follows: If the Steuermechanismus of the shutoff device --P-- in Fig.1 the represented, with both pins --42 and 43-- in the open position is, flows by the button --20-- on the desired temperature stopped, automatically water mixture by the connecting piece, controlled by the thermalstatic distributor --M--. If the desired by the button --98-- adjustable water levels in the bath tub, works the pressure-dependent release device is reached --78-- on the lever--91--, that the rocker arm--57-- releases, whereby this is moved into the position shown in Fig.2. It operates the shutoff device --P--, their two pins --42 and 43-- into the catch position to be pressed. 1Der thereby in the counter-pressure chambers --8 and 28-- the Einlaßventfle --A and B-- rising pressure causes a closing of these two valves, whereby the Wasserzulauf is completely interrupted into the bath tub. If the mixing valve by the button --117-- on the temporal controlling of the release device --114-- , operates the cam is adjusted --116-- the lever --91-- after the desired time interval. In order to in-be entitled the Wasserzulauf again or to set the automatic release device again on, only the pushbutton must --73-- are pressed in. The rocker arm becomes --57-- into the position shown in Fig.1, in that the shutoff device moves --P-- is opened. If during filling the bath tub or manipulation the shower of the WasserzuIauf is to be turned off prematurely, it, the pushbutton is sufficient --73-- to operate, around the FApphebel --57-- to move in catch position and the shutoff device --P-- out of operation to set (Fig.2). The substantial advantages of the mixing valve according to invention are folgende'. Closing the Wasserzulaufes, that off automatically by the pressure controlled release device --78--, or by the temporally steered shutoff device --114-- or by hand with the help of the pushbutton --73-- taken place, the temperature attitude changes in no way. If from there the Arraatur is taken later again in enterprise, it is necessary not to stop the temperature again. Shutoff device the affecting the auxiliary circles with small escape rate --P-- is relatively small. This shutoff device and the release devices are before the housing --1-- the mixing valve under a common guard plate arranged and find place in an only little deep cavity easy, so that they can be built in a recess of the simple thickness of the wall lining. The individual construction units are and remain after the installation easily accessible and making possible the use of the same equipment in very different application conditions. The automatic control of the quantity of water in bath tub or another container, guaranteed directly by the water mixture brought on an adjustable temperature, makes Energüeeinsparung possible, without it would be necessary to install expensive or sensitive additional apparatuses. With amended execution forms the Absperrvorrlchtung can --P-- with other shutoff devices in place of the pins --42 and 43-- , so in particular with turning slidegate valves, flaps are equipped od.dgl., which are steered by any appropriate mechanisms. 4s with simplified execution forms can be the shutoff device with only one Steuermechanismus, i.e. manuel] or automatic, equipped. Also control devices can be planned, which are operated by Einwurf of a currency or by electrical Niveauan2eigeeinrichtungen. The controlling of the main discharge by the work of the shutoff device, which circles on the Entleerungsso the counter-pressure chambers works, can be built also into Mischventfle, for others than the areas of application mentioned is suitable.
