進(jìn)口球型止回閥德國洛克產(chǎn)品詳情參數(shù)尺寸圖片 

一、進(jìn)口球型止回閥描述：

德國LOCKE洛克進(jìn)口球型止回閥都是采用橡膠包皮球為閥瓣，他們的原理是在介質(zhì)的作用下，可在閥體內(nèi)的滑道上前后滾動，從而起到打開或關(guān)閉閥門。單球型止回閥跟雙球形止回閥主要特點(diǎn)是流量大，流阻壓力損失小，密封性能好，消聲關(guān)閉，可減小水擊波。水平或垂直安裝均可。球形止回閥可用于冷水、熱水、工業(yè)及生活污水等管網(wǎng)的水泵出口，防止介質(zhì)倒流。

The imported ball check valves of Locke lock in Germany are all made of rubber coated balls. Their principle is that under the action of medium, they can roll back and forth on the slide way in the valve body, so as to open or close the valve. Single ball check valve and double ball check valve are characterized by large flow rate, small flow resistance pressure loss, good sealing performance, silencing and closing, which can reduce water hammer wave. It can be installed horizontally or vertically. The ball check valve can be used at the outlet of water pump of cold water, hot water, industrial and domestic sewage pipe network to prevent the backflow of medium.
