Abstract:
A flow blockage suction interrupt valve adapted for attachment to and fluid communication with a suction piping system of a pool system, said valve comprising:a housing defining a flow path between atmosphere and said piping system;a dynamic plug means positioned in said housing for opening and closing said flow path;a spring-loaded first actuator means attached to said dynamic plug means and operative to place said valve in an armed state or a tripped state, wherein in the armed state, said dynamic plug means closes said flow path, preventing atmospheric air from reaching said suction piping system through said valve and allowing normal pool system operation;a spring-loaded second actuator means normally not acting on said plug means adapted to reposition said plug means and open said flow path to relieve excessive suction in said piping system and;a triggering means activated by a predetermined vacuum level, operatively connected to second actuator means, wherein when said predetermined vacuum level activates said triggering means, said second actuator means acts on said plug means, predominating said first actuator means, opening said flow path, allowing atmosphere to enter said piping system, and placing said valve in said tripped state.
