產(chǎn)品詳情
簡(jiǎn)單介紹：
對(duì)夾式薄型保溫球閥適用于長(zhǎng)輸管線和一般工業(yè)管線，其強(qiáng)度、**性、耐惡劣環(huán)境性等在設(shè)計(jì)時(shí)進(jìn)行了特殊考慮，適用于各種腐蝕性和非腐蝕性介質(zhì)。它與浮動(dòng)球閥相比，工作時(shí)，閥前流體壓力在球體上產(chǎn)生的作用力全部傳遞給軸承，不會(huì)使球體向閥座移動(dòng)，因而閥座不會(huì)承受過大的壓力，所以固定式球閥的轉(zhuǎn)矩小、閥座變形小，密封性能穩(wěn)定、使用壽命長(zhǎng)，適用于高壓、大口徑場(chǎng)合。
