Valve for use in handling abrasive materials and method of wear prevention

A valve, comprising: a cylindrical casing, closed at its ends by covers, and having axially aligned inlet and outlet chambers midway of its length disposed at right angles to the axis of the casing. Communication between said chambers is controlled by a ported, fluid pressure operated, movable valve plate assembly, including parallel cylinders, each containing a stationary piston connected to the inner end of a pair of axially aligned rods, or guides, fixed at their outer end to the covers. Each rod has a passageway communicating at its inner end with one end of its associated cylinder for supplying operating fluid thereto to bodily reciprocate the valve plate assembly on said rods within the casing. An adjustable collar positions a fixed wear plate in sealing engagement with one side of the valve plate assembly, and a fluid pressure actuated loading ring urges a floating wear plate into contact with the other side of said valve plate assembly. The casing may be pressurized by gas or liquid, but in any event, such pressure is maintained equal to or preferably slightly lower than the fluid pressure applied to the loading ring, but higher than the pressure in the system in which the valve is installed. With such pressure relationship, any abrasive material being handled by the system is prevented from entering between the movable valve plate assembly and the fixed and floating wear plates, respectively, thereby eliminating or reducing leakage and wear to a minimum. When liquid is used as the casing pressurizing fluid and/or the operating fluid supplied to the cylinders, it is preferably filtered, and may also be circulated through heat exchange means, if cooling thereof is necessary or desirable. The invention further includes a method of preventing abrasion, i.e., scoring and galling of the valve seating surfaces when the valve is installed in a system handling abrasive material.

A valve comprises a cylindrical piston slidable in a bore in a casing and filled with a rubber or like closure member 6, which as the closure member moves from one limiting position to another alternately closes a port 7 with one of its ends and a passage 8 with the other end. The hollow piston 2 has an inwardly projecting ridge 5 which lies in a complementary groove in the closure member 6. The lower projecting part of the closure member 6 may have an upwardly curved lip which lies resiliently against the wall of the bore in the casing and prevents back flow of oil from the outlet port 10 to the inlet port 7. Fluid under pressure enters through the port 7, lifts the valve against the action of a spring 4 and presses the upper end of the closure member 6 against the passage 8 to close it. The fluid can then pass through port 10 to charge a dosing chamber. When the dosing chamber contains the desired quantity the flow of fluid through passage 7 is interrupted so that the spring 4 presses the piston 3 downwardly to close passage 7 and open passage 8 to permit the dosing chamber to discharge.

In a pre-compression configuration, the inner edge of the paddle member is spaced-apart from the proximal opening of the conduit and in a post-compression configuration, the inner edge of the paddle member engages and seals the proximal opening resulting in a built-in check-valve that is open when the paddle member is in the pre-compression configuration and closed when the paddle member is in the post-compression configuration.

Resilient plug stop valve - deforms locally for stick-free seating with valve body

Under compression closure a self-sealing flexible plug is withheld from valve bore passage entry. Lateral expansion into the bore would grip the plug, to inhibit free opening and increase the plug's wear. An internally derived compression localizes lateral expansion to the bore perimeter. The valve stem (20) in a screwed body sleeve (29) carries the plug (28). The stem is end flanged inside the plug. Axial plug compression, between the inside flange and an outside thrust washer (32) ridges (39) urges the plug outwards. A stem nut (24) and spring (26) in the handwheel (22) adjust the ridge height.

Gate valve

@ An improved gate valve has a body (12) with an inlet (16) into the valve chamber (14) and an outlet (18) from the chamber. A gate (26) is disposed in the chamber. A bonnet (20) with an opening therethrough is secured to the body and a stem (34) connected to operate the gate extends through the bonnet opening. A seat (38) is provided in the bonnet, a shoulder (40) is formed on the stem and heat responsive means (58) hold the stem out of back seating position during normal operation and release to back seat in response to excess heat. Body bushings (30, 32) surround the inlet and outlet and seal against the gate, each of the bushings having resilient sealing means and a sealing lip for sealing against a sealing surface on said body.

Sanitary gate valve with tapered valve plug

A gate valve assembly is provided which includes a valve body having a fluid passage extending laterally therethrough which has an inlet end and an outlet end, with means at the inlet end and at the outlet end to connect the valve body to a fluid conveying conduit. The passage has a bottom surface coplanar with the bottom of the conduit and is free of recesses capable of preventing the drainage of liquids. An axially extending valve chamber intersects the passage and is disposed perpendicularly to the axis of the passage, the chamber having an elliptical cross-section with its widest dimension perpendicular to the passage. An axially and non-rotationally movable valve member is fitted closely within the chamber and has an internal, downwardly tapered hard, core member formed of metal, glass ceramic or hard plastic material. The core is surrounded by an elastomeric elliptically cross-sectioned outer member. The elastomeric member has a generally flattened bottom surface adapted to engage the bottom of the passage and is dimensioned to close the passage when extended into the closed position.

Shut-off valve with valve plate

The subject matter of the invention is a shut-off valve with a valve plate (20) which can be displaced transversely to the flow (S) between inflow and outflow connections (12, 13). Arranged on either side of the valve plate (20) in the housing (10) are sliding and sealing plates (16) which are dimensioned in such a way that they completely overlap the sealing faces (22) of the valve plate (20) in both the open position (21) and the closed position (21'). The sealing pressure can be produced and set with adjusting screws (32) which act via a guide rail (30). <IMAGE>
