产品描述 Product Description进口静音式止回阀2.jpg

静音止回阀主要由阀体、阀座、导流体、阀瓣、导向套和压缩弹簧等零件组成.符合水利学的轮廓设计,取得较佳的流线型水路,内部付有导流体设计能保证最小压力损失,阀瓣行程较短,停泵能快速关闭,防止水锤水击的发生,达到静音的效果。

The silent check valve is mainly composed of valve body, valve seat, guide body, valve disc, guide sleeve, compression spring and other parts. It conforms to the outline design of hydraulics, and achieves a better streamline waterway. The internal fluid guide design can ensure the minimum pressure loss. The valve disc travel is short, and the pump can be shut down quickly to prevent the occurrence of water hammer and water hammer, so as to achieve the effect of silence.
