초록

An apparatus for detecting a leak in a conduit line includes a housing in fluid communication with the line, a valve including a valve seat and a valve element movable relative to the seat between opened and closed positions, a bypass line around the valve, a flow detector coupled to the bypass line for detecting fluid flow therethrough, and a mechanism configured to urge the valve element toward the closed position and to maintain the valve element in the closed position until a threshold pressure drop is reached. The mechanism may operate on the princi...
