ABSTRACT:
An improved relief valve of the type responsive to a predetermined thermal and/or pressure condition. The valve includes a valve body having an inlet, an outlet, an internal passage interconnecting the two, a valve seat about the passage and an opening coaxial with the valve seat, a poppet valve within the body, including a stem extending towards the opening and having a pressure responsive surface directed toward the inlet side of the valve seat, a closure disposed within the opening and having a central aperture slidably and sealingly receiving the stem, the closure being formed of a thin, relatively ductile material and having an outwardly extending lip frictionally captured by the body about the opening and sealingly engaging the body thereabout, the closure further including an annular convex ridge inwardly of the lip and within the body and a central pedestal directed oppositely of the ridge. A coil spring is interposed between the pedestal and the poppet valve for biasing the poppet valve against the valve seat. A thermally responsive actuator is carried by the valve body for opening the poppet valve in response to a predetermined thermal condition. A manual actuator is connected to the valve stem externally of the closure. The pressure setting of the valve is obtained by preloading the spring through deformation of the closure after the latter has been secured to the valve body.
