G500X沟槽式持压泄压阀用于消防或其他供水系统中,以防止系统超压或维持消防供水系统的压力,消防泵关闭后还可以减小水锤的冲击,也用于大型供水系统的水锤装置。本系列阀门产品广泛用于高层建筑、生活区等供水管网系统及城市供水工程。
Working Principle
G500X沟槽式持压泄压阀由主阀、泄压、持压导阀针阀、球阀、微形过滤器和压力表组成水力控制接管系统。利用水力自动操作,即可以作泄压阀用又可作持压阀用。作泄压阀用时,可维持供水路压力在设定的安全值之下;做持压阀用,可维持主阀上游水压在设定值之上,保持主阀上游供水压力。
Scope of Application
Urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other fields.
Product Features
本产品利用水力自力控制,不需要其它装置和能源,保养简便,一阀多用。
