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.
摘要翻译：膜片/弹簧操作的压力释放阀，其具有与阀的出口孔基本相同的流动面积的感测通道，由此两个隔膜的故障导致“故障打开”构造。此外，平衡隔膜的有效面积基本上与出口孔的座密封件的座位面积相同，使得阀出口上的压力或真空度在平衡隔膜和阀座密封件上均匀地推或拉，从而平衡力和保持阀稳定。

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.
