用途 User 用于高层建筑或其它供水系统的水泵出口,可以防止介质倒流,而且可以减小水锤现象,以达到安全及安静的效果。 Water pump outlet for high-rise buildings or other water supply systems can prevent backflow of the medium and can reduce water hammer phenomenon to achieve safe and quiet effect. 可防止水锤和水击现象的产生,达到缓闭消声的效果。是能够调控启闭速度的止回阀,在水泵启动或停止运行时,可现场调节至开启或关闭速度。 Water hammer and water hammer can be prevented to achieve the effect of slow - closing. It is the check valve that can control the opening and closing speed and can be adjusted to the best opening or closing speed when the pump starts or stops running. 停泵后,介质倒流,阀门上腔压力大于下腔压力,阀瓣下落关闭。而控制回水进入膜片上腔的速度,就可以调整阀门的关闭速度,从而达到缓闭的目的。 After stopping the pump, the flow of the medium is inverted, the pressure of the chamber pressure is greater than that of the lower chamber, and the valve is closed.Controlling the speed of the return water to the cavity of the diaphragm can adjust the closing speed of the valve to achieve the purpose of slow closure. 执行标准 Executive standard 法兰尺寸 Flange dimensions:GB/T 17241.6 试验检验 Test test:GB/T 13927 安装图典型 Installation diagram
