BWO5X Safety pressure relief valve
产品介绍
该阀由主阀及外装控制导阀组成。主要安装于建筑物被保护给水系统的旁路中，保障主阀上游供水区的压力，当给水管中压力超过泄压阀设定压力时，泄压阀开启，防止管线及设备因超压而损坏。该阀主要用于高层建筑消防测试循环系统的泄压，是弹簧式安全阀的升级换代产品。
Product introduction
The valve is composed of a main valve and an external control pilot valve. It is mainly installed in the bypass of the protected water supply system of the building to ensure the pressure of the upstream water supply area of the main valve. When the pressure in the water supply pipe exceeds the set pressure of the pressure relief valve, the pressure relief valve is opened to prevent the pipeline and equipment from being damaged due to overpressure. The valve is mainly used for the pressure relief of the circulating system of the fire test in high-rise buildings, and is the upgrading product of the spring type safety valve.
