隔膜式雨淋报警阀是雨淋报警阀的一种类型，雨淋报警阀和设有开式喷头的管网配套使用组成雨淋系统。
隔膜式雨淋报警阀用橡胶隔膜把阀体供水腔和系统腔隔开，靠控制腔内的水压高低来打开或关闭隔膜，控制着水流的断和通，雨淋报警阀处于伺应状态时，控制腔内的水压与供水压力相等，隔膜处于关闭状态，水不能进入系统侧，当发生火灾时，启动电磁阀使控制腔泄压，供水腔直接受供水压力的推动，打开隔膜使水流入系统腔，进入系统管网进行灭火。
The diaphragm type deluge alarm valve is one of deluge alarm range, which deluge system was composed by deluge alarm valve and pipe network with open sprayer.
The diaphragm type deluge alarm valve, separating water supply chamber and system chamber with rubber diaphragm, depends on the water pressure in the control chamber to open and close the diaphragm, thus controls the water flow. When it’s in a ready condition, the diaphragm is in close state for equal water pressure between the control chamber and water supply chamber and so water cannot enter into side of
the system. If fire occurs, the starting magnetic valve would decompress the control chamber, which water supply pressure would directly push the control chamber to open the diaphragm allowing water flowing into the system chamber and the pipe network to extinguish the fire.
