摘要： For operating pumps above the respective system resistance for all volume flows, for a spring-loaded, directly acting overflow valve for limiting the pressure in a system in which a liquid is lifted by a positive-displacement pump and flows through the system with varying rates of flow, the valve chamber (1) and the valve body (22) with the valve head (14) placed therein are constituted in such a way that the valve head, after lifting off from the valve seat (3), has a second active diameter which is bigger than the first active diameter, whereby the valve head (11) simultaneously releases, with increasing stroke of the valve body (22), an enlarging flowing-through cross section, whereby the valve body (22) is constituted in one part as a valve piston (11) sliding in the valve chamber (1) with a third active diameter which is bigger than the second active diameter so that the liquid flowing through the valve chamber (1), the valve being opened, produces a pressure difference which acts onto the valve piston (11) against the action of the first spring (21).

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： The present invention comprises a valve body (24) with an inlet (28) and an outlet (30), and an inlet-closing poppet (32) moveably disposed within a chamber (26) in the valve body, the poppet incorporating a piston head (34) whose face (36) opposes the inlet and from which projects a plug (62) for closing-off the inlet (28) from the remainder of the piston face (36) when the poppet is at its inlet-closing position. A spring (54) urges the poppet towards its inlet-closing position with sufficient force to keep the inlet closed until the fluid reaches a preselected cracking pressure, whereupon the spring allows the poppet to be displaced slightly, exposing the remainder of the piston face to the fluid. The action of the fluid on the piston face is then sufficient to drive the poppet fully back to an annular stop (60) provided within the valve body whose engagement also serves as a partial seal about the periphery (70) of the piston. One or more small channels (58) formed in the piston head direct fluid from the face of the piston to its backside with sufficient pressure drop to assure that the poppet will remain situated against the stop. In the preferred embodiment, these passages lead into the interior of a hollow, reciprocable connector (40) which both lends support to the piston but also serves as a conduit towards the outlet of the valve.
摘要翻译：本发明包括具有入口（28）和出口（30）的阀体（24）和可移动地设置在阀体中的腔室（26）内的入口关闭提升头（32），所述提升阀结合有活塞头部（34），其面（36）与入口相对，并且当提升阀处于其入口关闭位置时，插塞（62）从活塞面（36）的其余部分突出地插入入口（28）。弹簧（54）以足够的力促使提升阀朝向其入口关闭位置，以保持入口闭合，直到流体达到预选的开启压力，于是弹簧允许提升阀轻微移动，将活塞的其余部分暴露于流体。因此，流体在活塞面上的作用足以将提升阀完全驱回到设置在阀体内的环形止动件（60）上，其接合还用作围绕活塞的周边（70）的部分密封。形成在活塞头中的一个或多个小通道（58）将流体从活塞的表面引导到其后侧，并具有足够的压力降，以确保提升阀将保持靠在止动件上。在优选实施例中，这些通道引入中空的可往复运动的连接器（40）的内部，这两个连接器都支撑活塞，但也用作朝向阀出口的导管。
