摘要： A pressure retention valve including a housing having an inlet passage and an outlet passage that can be connected together and a separating diaphragm subdividing the housing into two portions, wherein, in operation of the valve, a first portion conveys fluid and a second portion is fluid-free. The valve further includes a valve seat defining an end of the inlet passage, arranged in the fluid-conveying portion of the housing, and has a first sealing surface, a shut-off body which is arranged movably in the fluid-conveying portion of the housing and has a second sealing surface, and a spring element having a spring force, which is arranged in the fluid-free portion of the pressure retention valve. The spring element is so arranged that its spring force prestresses the second sealing surface in the direction towards the first sealing surface so that in a position of the shut-off body that closes the valve the sealing surfaces are in engagement with each other and the shut-off body separates the inlet passage from the outlet passage. The inlet passage is so arranged that a fluid flowing in through the inlet passage in operation of the valve is applied to the shut-off body in such a way that the fluid exerts on the shut-off body a force which acts in opposition to the spring force of the spring element. The shut-off body has a guide portion which extends into the inlet passage, and the inlet passage is portion-wise of such a design configuration that it forms a guide bush in which the guide portion of the shut-off body is guidedly received.

摘要： A safety diaphragm for a diaphragm pump, which makes it possible to detect a rupture of the diaphragm during operation or when at a standstill. The diaphragm has at least two diaphragm layers (1, 2) arranged lying one on top of the other The diaphragm has a clamping region (E) for fixing the diaphragm in a pump and has an adjacent operational region (A). The diaphragm layer (1, 2) are connected to each other so that they are sealed against penetration of liquid and/or gas between the diaphragm layers (1, 2). The diaphragm, in one section of the clamping region (E), has a sensor region (S) where the diaphragm layers (1, 2) are formed so that, in the case of an increase in pressure between the diaphragm layers (1, 2), the layers in sensor region (S) deform more easily than in the other sections of the diaphragm.
