國標(biāo)固定式球閥的詳細(xì)資料：產(chǎn)品概述國標(biāo)固定球閥是新一代高性能球閥，適用于長輸管線和一般工業(yè)管線，其強(qiáng)度、安全性、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，不會使球體向閥座移動(dòng)，因而閥座不會承受過大的壓力，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，適用于高壓、大口徑場合。*的彈簧預(yù)閥座組件，具有自緊特性，實(shí)現(xiàn)上游密封。每閥有兩個(gè)閥座，每個(gè)方向都能密封，因而安裝沒有流向限制，是雙向。國標(biāo)固定球閥有二塊式和三塊式兩種閥體結(jié)構(gòu)，中法蘭用螺栓連接，密封采用增強(qiáng)聚四氟乙烯鑲?cè)氩讳P鋼圈內(nèi)，鋼圈后部沒有彈簧保證閥座緊貼球體，保持密封。上下閥桿均沒有PTFE軸承，減少磨擦，操作省力，小軸底部沒有調(diào)整片，保證球與密封圈的接處位置。全通徑：閥門流量孔徑與管線內(nèi)徑*，以便管線清掃。國標(biāo)固定球閥產(chǎn)品特點(diǎn)1、采用圓柱形彈簧或波形彈簧預(yù)載的襝性可動(dòng)金屬閥座結(jié)構(gòu)，密封預(yù)緊力設(shè)計(jì)合理、閉啟靈活，有效保證密封的可靠性。2 、采用特殊結(jié)構(gòu)裝置的閥桿，不僅確保填寫料處還會滲漏，且防止了閥桿脫出。3、根據(jù)用戶的需要，可設(shè)計(jì)成適應(yīng)粉塵(包括含固體顆粒)，漿料等介質(zhì)的結(jié)構(gòu)，使球閥耐磨及耐高溫性能更好。4、本身具有防火防靜電功能。5、該結(jié)構(gòu)球閥應(yīng)按規(guī)定流向使用。公稱通徑：DN50-300mm
