摘要： A compressor safety valve releases an abnormal pressure to the outside through a discharge port when the pressure in a compressor has increased abnormally. The valve comprises a cap having an anchoring part integrally formed therewith and mounted on a head portion of a valve main body in an attachable and detachable manner. The valve further comprising an elastic body interposingly mounted between the cap and the head portion of the valve main body in a compressed state and in close contact with the head portion of the valve main body. The elastic body is interposed so as to cover the entirety of a peripheral surface of the discharge port and the cap is anchored to the head portion of the valve main body by the elastic repulsive force of the elastic body, so that the discharge port is closed by the elastic body and the cap.

摘要： A fast opening pressure relief valve (200) for providing pressure relief for a vessel. The valve (200) has an ejector (216) and a sleeve structure (210) in which the ejector (216) moves longitudinally. The ejector (216) is constructed of material that will expand outward slightly upon pressurization, increasing friction between staging glands (202) provided on the sleeve structure (210) and buckling glands (206) provided on the ejector (216). Also, as pressure on the ejector (216) increases, the buckling rings (206) deform slightly to release their grip on the staging glands (202) and move past them. Once the buckling rings (206) move past the staging glands (202), the pressurized ejector (216) quickly moves to its open position, i.e. opening within 2 and 3 milliseconds, thereby releasing the pressure on the vessel. The valve (200) can be reset by returning the ejector to its closed position.

摘要： A reset relief valve with a body having an inlet port, an outlet port, and an interior wall partially defining an enclosed chamber, a piston disposed in the body and moveable between a first position at which the piston is disposed in fluid flow-blocking relationship between the inlet port and the outlet port of the body and a second position at which the piston is removed from that position, a piston having a head with opposed end surfaces one of which defines a portion of the enclosed chamber and at least one fluid flow passageway extending through the head and providing fluid communication between the enclosed chamber in the body, and a second chamber above a moveable disc in the piston. A preferred embodiment includes the crank assembly with cross bar support and a T-bar to prevent downward movement of the disc.

摘要： A failed nozzle relief (FNR) valve has a resetting mechanism that resets the valve when a filler cap is replaced over the filler cup. The FNR valve has an annular seal that surrounds a filler neck opening. The annular seal seats against a ring having at least one aperture that creates an alternative fluid flow path. During a failed nozzle shutoff condition, the annular seal separates from the ring, opening the aperture to allow fluid to flow through it. The FNR valve also has a reset lever that is pressed downward when the filler cap is replaced, thereby forcing the seal back against the ring.

摘要： A flame front diverter element is designed to cause a minimal pressure drop under normal venting conditions when process vapors need to pass through the explosion protection system and to other equipment connected to the manifold system. In the event of a deflagration, the flame front diverter directs the high-speed pressure wave towards a bi-directional rupturable disc causing the rupturable disc to open thus creating an aspiration effect on the opposite bi-directional rupturable disc.

摘要： A pressure relief system for detecting and correcting an overpressure situation in a pressurized fluid. The system includes a pressure responsive member such as a buckling pin configured to mechanically collapse when a predetermined force is applied to the member. An actuator assembly axially compresses the member in response to the pressure of the fluid and rotates a first shaft upon mechanical collapse of the member. A bypass valve assembly establishes a bypass path for the fluid upon rotation of a second shaft. A clutch mechanism decouples the first and second shafts prior to and during initial stages of mechanical collapse of the member and subsequently couples the first and second shafts during remaining stages of mechanical collapse of the member. In this way, forces associated with the bypass valve assembly are isolated from the actuator assembly during steady state operation and during the initial stages of mechanical collapse.

摘要： A backflow valve which includes a closure gate pivotally mounted along a substantially vertical pivot axis to one of the opposed sides of the valve body. A closure gate engaging profile positioned in a bottom of the valve body locks the closure gate in the open position. The closure gate is biased into the closed position. The closure gate moves to the closed position upon floating free of the closure gate engaging profile.
