恒压阀、以及具有恒压阀的报警阀站和自动灭火设备
摘要：
本发明涉及一种恒压阀(45)，其尤其用于自动灭火设备(200)的报警阀站(100)，所述恒压阀具有：流体入口(16)；流体出口(15)；在所述流体入口和所述流体出口之间的流动通道；设置在所述流动通道中的、能够在备用位置和触发位置之间来回运动的控制活塞(3、8)，所述控制活塞具有朝向所述流动通道的第一活塞面(S)和第二活塞面(S2)。根据本发明提出，所述恒压阀具有与所述流动通道分开的切换室，所述切换室具有与所述切换室引导流体地连接的切换压力入口(4)，其中所述第二活塞面(S2)朝向所述切换室(4a)，其中所述恒压阀(45)具有固定元件(21)，所述固定元件与所述恒压阀(45)的所述控制活塞(3、8)耦联并且在所述备用位置中吸收作用到所述控制活塞(3、8)的第一活塞面(S)上的力。
摘要（英）：

The invention relates to a constant-pressure valve (45), in particular for an alarm valve station (100) of a sprinkler system (200), said valve comprising a fluid inlet (16), a fluid outlet (15), a flow channel between the fluid inlet and the fluid outlet, a control plunger (3, 8) which is disposed in the flow channel and can move back-and-forth between a stand-by position and a release position,the plunger comprising a first plunger face (S) facing the flow channel and a second plunger face (S2). According to the invention, the constant-pressure valve has a switching chamber which is separate from the flow channel and which has a switching-pressure inlet (4) that is fluidically connected to the switching chamber, the second plunger face (S2) facing the switching chamber (4a). The constant-pressure valve (45) has a securing element (21) which is coupled to the control plunger (3, 8) of the constant-pressure valve (45) and which, in the stand-by position, absorbs the forces acting on the first plunger face (S) of the control plunger (3, 8).
