本实用新型提供的Y型雨淋阀主阀的工作原理是:当液体由阀盖2上的管路连接口进入控制腔16时,在压力的作用下推动隔膜3带动密封组件(导向轴5、托盘6、密封胶板7、支架8、压盘9)移动,使密封胶板7和阀座4接触而密封(如图2所示)。此时隔膜3紧贴支架8和阀体1,保护隔膜3在高压时不被破坏;此时,阀盖2和隔膜3形成的空腔即为控制腔16。当控制腔16内的压力下降到一定值时,进水腔14中通入的带有压力的流体会推动密封组件移动而打开阀门(如图1所示)。The working principle of the Y-type deluge valve main valve provided by the utility model is: when the liquid enters the control chamber 16 from the pipeline connection port on the valve cover 2, the diaphragm 3 is pushed to drive the sealing assembly (guide shaft 5) under the action of pressure. , The tray 6, the sealing rubber plate 7, the support 8, the pressure plate 9) move, so that the sealing rubber plate 7 and the valve seat 4 contact and seal (as shown in Figure 2). At this time, the diaphragm 3 is close to the support 8 and the valve body 1 to protect the diaphragm 3 from being damaged under high pressure; at this time, the cavity formed by the valve cover 2 and the diaphragm 3 is the control chamber 16. When the pressure in the control chamber 16 drops to a certain value, the fluid with pressure introduced into the water inlet chamber 14 will push the seal assembly to move and open the valve (as shown in FIG. 1).
