摘要： A diaphragm/spring operated pressure relief valve having a sensing passage of substantially the same flow area as the outlet orifice of the valve whereby failure of either diaphragm results in "fail open" configuration. In addition the effective area of the balancing diaphragm is substantially the same as the seat area of the seat seal of the outlet orifice such that a pressure or vacuum on the valve outlet pushes or pulls equally on the balancing diaphragm and the valve seat seal thereby balancing the forces and keeping the valve stable.

摘要： A handheld device for finding the angle of a slope of a surface or verifying whether a surface is level or perpendicular which has a housing with a generally planer configuration, two perpendicularly intersecting straight edges, an arcuate slot comprising greater than 90° having a concave and a convex side positioned in said housing said concave side facing and opposed to said perpendicularly intersecting straight edges, a sealed tubular member filed with liquid and having one gas bubble therein, position along the arcuate slot and visible on at least one side of said housing. The tubular member is calibrated to determine 0 and 90 degree points which are marked on the housing and a plurality of indicia along said housing adjacent to said slot, indicating degrees between 0° to 90°.

摘要： A diaphragm/spring operated pressure relief valve having a sensing passage of substantially the same flow area as the outlet orifice of the valve whereby failure of either diaphragm results in “fail open” configuration with the addition of a sensing inlet shroud located to capture the total pressure at the inlet and channel it to the sensing chamber to allow the valve to relieve full rated capacity in the event the sensing diaphragm is ruptured.

摘要： A check valve having an elongated body with bore therethrough, the bore having a small diameter section abutting a downstream frustoconical section with an increasing diameter, a ball positioned downstream of the small diameter section and movable in the frustoconical section and a pin blocking the bore to keep the ball at or near the frustoconical section and near to the small section, such that a reversal in fluid flow will seat the ball within the frustoconical section and block the bore.
