固定球閥產品概述
Q347F/H/Y蝸輪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管線,其強度、安全性、耐惡劣環境性等在設計時進行了特殊考慮,適用于各種腐蝕性和非腐蝕性介質。它與浮動球閥相比,工作時,閥前流體壓力在球體上產生的作用力全部傳遞給軸承,不會使球體向閥座移動,因而閥座不會承受過大的壓力,所以固定式球閥的轉矩小、閥座變形小,密封性能穩定、使用壽命長,適用于高壓、大口徑場合。的彈簧預閥座組件,具有自緊特性,實現上游密封。每閥有兩個閥座,每個方向都能密封,因而安裝沒有流向限制。本閥有二塊式和三塊式兩種閥體結構,中法蘭用螺栓連接,密封采用增強聚四氟乙烯鑲入不銹鋼圈內,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徑一致,以便管線清掃。
蝸輪固定球閥產品特點
1、采用圓柱形彈簧或波形彈簧預載的襝性可動金屬閥座結構,密封預緊力設計合理、閉啟靈活,有效保證密封的可靠性。
2、采用特殊結構裝置的閥桿,不僅確保填寫料處還會滲漏,且防止了閥桿脫出。
3、根據用戶的需要,可設計成適應粉塵(包括含固體顆粒),漿料等介質的結構,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、該結構球閥應按規定流向使用。
