摘要： A pilot operated valve having an inlet passageway (8) surrounded by an annular seat (6) surrounded by an outlet passageway (110) respectively. The main valve member (7) having turbulence shield (11) of greater diameter than the external diameter of the seat (113) and deflector plate (34). Turbulence shield (11) slows the descent of the valve during closing and prevents water hammer. Pressure chamber inlet (37 or 14) may have a check valve (15 or 21 respectively). Trigger passageway (17) is remotely operated depending on the application. For example a latching solenoid arrangement (figs. 3 to 7), float (figs. 10 and 11), handle or pressure balanced piston (fig. 15). The latching arrangement involves two solenoids with interacting armatures. As a refuelling valve trigger passageway (17) has a first pilot valve at a distal end opened upon coupling to the destination tank to vent the pilot chamber (12) and open main valve (7). A float comprises a second pilot valve which closes the trigger passageway prior to disengagement of the coupling to trigger the closing ot the main valve (6). A third manually operated pilot valve may be located on the main valve body. As a faucet valve (fgs. 12 to 14) the main valve resides under the counter and the pilot above. In one such arrangement the passageway (17) is concentric with the outlet (10), in another the pressure chamber inlet (14) and trigger (17) passageways are concentric. The pressure chamber (12) and outlet (10) may be concentric and in line (fig. 12).

摘要： A fluid flow safety device comprising a body having an inlet end for connection to a fluid supply and an inlet passageway which leads to a selective fluid flow sensor chamber and located at the outlet end of the said sensor chamber is a sealing means which encircles the outlet orifice and this outlet orifice is of smaller cross section than that of the sensor chamber, said outlet orifice leading from the sensor chamber into a pressure chamber within the body. Between the inlet end of the sensor chamber and the sealing means is a tapered section, wherein the bore of the sensor chamber decreases in diameter as it nears the sealing means. A movable plug which is positioned within the selective fluid flow sensor chamber can move between the inlet passageway end stop of the sensor chamber and the outlet orifice, and the movable plug is of greater diameter than the sensor chamber outlet orifice and is able to form a seal with the sealing means. This seal can occur when the flow of fluid through the sensor chamber is above a predetermined value. Within the pressure chamber is a movable piston which makes a sliding and sealing contact with it and whose sliding movement from a rest position increases or decreases the volume of the said pressure chamber. A passageway leading from the pressure chamber to an outlet aperture is connectable to further fluid transport mechanisms. One embodiment includes an indicator mark on the movable piston which is visible only when the pressure in the pressure chamber is above a predetermined value and a movement of the movable piston from a rest position fully towards the sensor chamber will deny a seal to be made between the movable plug and the sealing means. In the preferred embodiment, the movable piston is the primary valve mechanism which forms a seal between the inlet and outlet passageways. A sensor chamber shield encircles the sensor chamber by forming, defining and separating the internal length of the sensor chamber passageway from that of the inlet or any other passageway.

摘要： A pressure control valve (10) is disclosed which includes an inlet (11); an outlet (12); a valve body (13) between the inlet (11) and the outlet (12); a piston (14) having opposed smaller and larger ends (15, 16) each having a circumferentially extending piston wall, the piston (14) being slideably received within the valve body (13) and having a bore (19) therethrough; a porting assembly (20, 22) for providing a fluid passageway between the inlet (11) and the bore (12), and biasing means (26) for biasing the piston (14) against the pressure at the outlet (12) towards a first position proximate the outlet (12) from a second position proximate the inlet (11); wherein in the first position (FIG 1) fluid communication is made between the inlet (11) and the outlet (12) via the porting assembly (20, 22) and the bore (19), and in the second position fluid communication between the inlet (11) and the outlet (12) is prevented by the circumferentially extending piston wall of the smaller end (15) of the piston (14) cooperating with the porting assembly (20, 22) to close the fluid passageway between the inlet (11) and the bore (19).

摘要： A fluid flow safely device comprises a body having an inlet end for connection to a fluid supply and an inlet passageway (8, 48, 103) which leads lo a selective fluid flow sensor chamber (9, 49, 115) having a sealing means (10, 50) which encircles the outlet orifice (11, 51) of smaller cross section than that of the sensor chamber, said outlet orifice leading from the sensor chamber into a pressure chamber (12, 52) within the body leading to an outlet. Between the inlet end of the sensor chamber and the sealing means is a tapered section (13, 117), wherein the bore of the sensor chamber decreases in a diameter as it nears the sealing means. A sensor chamber shield (120) may encircle the sensor chamber by forming, defining and separating the internal length of the sensor chamber passageway from that of the inlet or any other passageway. A ball (16, 56, 119) in the sensor chamber moves between the inlet passageway end of the sensor chamber and the outlet orifice, to form a seal with the sealing means when flow through the sensor chamber is above a predetermined value. Within the pressure chamber is a movable piston (20, 60, 131) in sealing contact with it to increase or decrease the volume of the pressure chamber. Movement of the movable piston from a rest position fully towards the sensor chamber will deny a seal to be made between the ball and the sealing means. The movable piston may be a primary valve mechanism which forms a seal between the inlet and outlet passageways. The movable piston may include an indicator mark visible only when the pressure in the pressure chamber is above a predetermined value. Embodiments for LP gas include separate use of sensor chamber or movable piston with or without primary valve.

摘要： A main water supply safety valve to provide a maximum pressure to a water conditioning apparatus while preventing any shock load of water hammer from passing into the apparatus while still providing a single or dual check valve. When pressure acting on outlet side (306) of stepped piston (311) exceeds the force of spring (337) and pressure acting on the inlet side (304) of piston (311), the piston moves to shut off flow. The valve also has check valves (338 and 334) and a stepped ring (325) which moves to expose ring (330) to indicate that seals (312 and 313) have leaked or failed. In a different embodiment, the piston (311) has an internal seat (207) at the outlet end of piston bore (317) and a stepped shaft (203) in piston bore (317) biased towards the valve inlet (304). The step shoulder of shaft (203) seals against internal seat (207) when the piston (311) moves towards inlet (304) and a protruding portion of shaft (203) abuts against a stop.
