德國洛克品牌供應(yīng)進口球型止回閥

進口球型止回閥結(jié)構(gòu)特點：

1、使用壽命長、可靠性高

2、動作靈敏、密封性能好

3、流道通暢、流體阻力小

4、閥瓣行程短、關(guān)閥沖擊力小

5、閥瓣關(guān)閉快速，水錘壓力小

6、水平或垂直管道均可使用，安裝方便

7、整體結(jié)構(gòu)、簡單緊湊、造型美觀

8、結(jié)構(gòu)長度短，其結(jié)構(gòu)長度只有傳統(tǒng)法蘭止回閥的1/4~1/8

進口球型止回閥描述：

德國《DE LOCKE》洛克進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。

Description of inlet ball check valve:
German "de Locke" Locke imported ball check valves all use rubber coated ball as disc. Their principle is that under the action of medium, they can roll back and forth on the slide in the valve body, so as to open or close the valve. The main features of single ball check valve and double ball check valve are large flow, small flow resistance pressure loss, good sealing performance, silencing closing, and reducing water hammer wave. It can be installed horizontally or vertically. The ball check valve can be used at the pump outlet of cold water, hot water, industrial and domestic sewage pipe network to prevent medium backflow.
