SUCTION DEVICE AND METHOD FOR OPERATING A SUCTION DEVICE

Flow blockage suction interrupt valve

A flow blockage suction interrupt of the present invention reduces the dangerous possibility of bodily suction entrapment of a bather in a swimming, wading, or hydrotherapy pool. The safety valve operates to instantaneously introduce atmosphere into a suction piping system of a pool when a dangerous vacuum condition is detected. The incoming atmosphere breaks the vacuum, freeing entrapped bather. The safety valve includes a dynamic plug and dual spring-loaded actuators, one closing and one opening the valve to atmosphere. The closing actuator is dominant until the opening actuator is triggered by the dangerously high vacuum level that accompanies bodily suction entrapment. The preferred embodiment incorporates a spring-loaded telescopic actuator shaft that is spring-loaded to open fully once triggered, and is triggered by a factory-calibrated diaphragm-actuated suction sensor. Once this safety valve has been tripped, it must be manually reset by the pool operator.

Selectable detent relief valve

A selectable detent relief valve of this invention is used to operate a hydraulic detent mechanism on a manually operated spool valve. This design has three modes of operation, no-detent, continuous detent and kick-out detent. The no-detent position allows flow to pass through the relief valve, from a first port to a second port and bypass the relief function. The pressure created, disengages the detent mechanism in the spool valve. The spool always returns to neutral position as long as pressure is present. The continuous detent position blocks the flow from a first port to a second port. The kick-out detent position allows flow to pass from the first port to the second port to override (kick-out) the detent mechanism in the spool when the pressure is greater than 2600 psi.

Patent GB1301981A

1301981 Valves AMERICAN AERO INDUSTRIES Inc 16 Feb 1971 4765/71 Heading F2Y In a pressure relief valve, surges of pressure below a predetermined pressure value are accommodated by movement, relative to a seat member 60, of a valve member 32, 50 which is releasably held by a latching mechanism D, the movement being insufficient to effect opening of the valve and hence communication between the inlet 19 and the outlet 30. Such communication is, however, established upon the surges exceeding the predetermined pressure value. In the former instance, the valve member part 50 merely moves within seat member 60 to an extent determined by the maximum possible axial movement of the latching mechanism D within the confines of bore 21. Upon the pressure rising above the predetermined value, the displacement of valve member 32, 50 is such that the ball member 40 of the latching mechanism D leave the bore 21 and so leave the recessed portion 33 of the valve member part 32. Accordingly, the valve member 32, 50 is rendered free of the action of spring 26 and so continues to move upwardly until it abuts the valve housing cover R, the passage between the inlet 19 and outlet 30 being thus opened. Subsequent to the release of pressure, the valve member is reset manually by depressing rod 34 until the ball members 40 re-enter the recess 33 and so hold the valve member in a state wherein its terminal part 50 is allowed a certain movement relative to the seat 60 without actual opening of the valve. The opening pressure of the valve is adjustable by appropriate manipulation of housing cover 29 which results in an adjustment of the tension of spring 26.

The invention relates to a valve device in which elements are arranged in the region of the valve seat, which break by vibration or change in shape resulting at minus temperatures ice between valve closing body and valve seat and thus ensure the function of a secondary air system even at minus temperatures.

Balanced pressure reducer for respiration equipment has valve seat made from at least two materials with different degrees of rigidity

The pressure reducer, comprising a body (7) with a highpressure inlet (10) and a low-pressure outlet (11) separated by a valve (1) that is closed by interacting with a seat (6), has the valve seat made from at least two materials with different degrees of rigidity, with the less rigid material forming the contact zone for the valve when closed. The valve seat consists of a bush (61) of a rigid synthetic material, with one end (62) covered by a less rigid material, e.g. by overmoulding.

1,208,497. Valves. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 29 May, 1969 [12 June, 1968], No. 27905/68. Heading F2V. Excess pressure, e.g. from an unintentionally fired rocket or a burst pressure vessel on a plate 27 moves a plunger 26 downwards to release balls 25 from a V-shaped groove 12 and permit a piston 22 to move upwards under fluid pressure in hose 40 to allow the fluid to flow out of outlets 36 via passages 19 and 35. The fluid is water or other fire extinguishing medium. The plunger may be replaced by an elongate member with ball-engaging concaveends which member is bent or broken by a pointed bifurcated end of an axially guided shank rigid with the plate. The outlet passages may extend in different directions. A drain 20 and an air bleed 16 are provided.

Closure valve for waste gas chamber

The invention concerns a safety valve (2) for a chamber (4) comprising a frame (10), a shutter (30), control means for actuating (48, 60) the shutter to open and to close an orifice (18) of the chamber, and further releasing means (46) for automatically closing the shutter when the pressure level in the chamber reaches a predetermined threshold. The shutter (30) is mounted sliding relatively to the frame (10).
