Buckling pin actuated, pilot operated pressure relief valve

摘要: The present invention provides a method, apparatus and system for using sacrificial buckling pin technology reliable actuated safety relief valve pilot system. fails at predicted, predetermined pressure through transfer of force exerted by the on sensing piston or diaphragm to pin. failure triggers release latch mechanism that releases actuator assembly slide away from seat initiate flow. use as trigger valves with high flow rates without large, unmanageable pins. control single multiple operating together is preferred particularly advantageous.
