金屬硬密封(鍛鋼)球閥
產(chǎn)品概覽
鍛鋼法蘭式高壓球閥關閉部件球體圍繞閥體中心線旋轉(zhuǎn)以開啟和關閉閥門,密封件嵌在不銹鋼閥座中,金屬閥座上裝有彈簧,當密封面磨損或燃燒時,在彈簧的作用下推動閥座與球體形成金屬密封。具有獨特的自動泄壓功能,當閥腔介質(zhì)壓力超過彈簧預緊力時,出口閥座退球,達到自動泄壓效果,泄壓后閥座自動復位,適用于水、溶劑、酸和氣體等一般工作介質(zhì),也適用于介質(zhì)工況,如氧氣、過氧化氫、甲烷和乙烯,它已在各個行業(yè)得到很好的應用。
產(chǎn)品結(jié)構(gòu)特點:
1、本產(chǎn)品所有部件均為鍛件。
2、采用底裝式閥桿,設置倒密封結(jié)構(gòu),確保填料處可靠密封,防止閥桿脫出。
3、采用鑲嵌式閥座,閥座后方設有O型圈,確保介質(zhì)不外漏。
