在自动喷水灭火系统当中，雨淋 报警阀的应用较为普遍。目前，根据国内各专业生产厂家的设计结构不同，按照密封原理划分，主要有隔膜式和杠杆阀瓣式两大类型。杠杆阀瓣式雨淋阀是近几年来推广使用的一种新型的雨淋阀，它克服了隔膜式雨淋阀存在的缺陷，较隔膜式为先进，在工程 Among the sprinkler systems, the application of rain alarm valve is more common. At present, according to the domestic professional manufacturers of different design structures, divided according to the principle of sealing, there are two major types of diaphragm and lever valve type. Lever disc valve deluge valve is the promotion of the use of a new type of deluge valve in recent years, it overcomes the defects of the diaphragm deluge valve, diaphragm than the advanced, in engineering
