H76X止回阀由阀体、阀瓣、阀杆及弹簧等零件组成,采用对夹连接。由于阀瓣的关闭行程短,并且有弹簧加载,可显著减少水锤现象。该阀主要适用于城市、工业及高层建筑给水、排水管网上。由于其结构长度比一般止回阀短,对有安装空间限制的场所较为适用。
1. Short length, small volume and light weight of product structure;
2, sealing surface can be selected according to different working conditions soft seal or hard seal material sealing performance;
3, the opening pressure is very small, the disc can be fully opened under a very small pressure difference;
4. Fast disc closing, low water hammer pressure;
5. Horizontal or vertical pipe can be used for easy installation;
6. The material of the parts and the form and size of the valve end face can be reasonably selected according to the actual working conditions or the requirements of users.
Meet various engineering needs.
