DTBM-G系列API6A雙聯固定球閥

技術參數:

設計标準: API6A

連接方式: API6A

結構長度: API6A

檢驗和試驗: API6A

口徑範圍: 1-13/16" ~ 11"

壓力範圍: 2000psi ~ 20000psi

溫度範圍: -60℃ ~ +121℃

産品規範級别: PSL1 ~ PSL3/3G

産品性能等級: PR1, PR2

驅動方式: 齒輪箱

可選驅動方式: 手柄等結構特點

結構特點:

◇ 三片式、鍛鋼、雙聯球、固定球、軟密封/硬密封

◇ 一台閥門裝有兩個球體, 可以同時開關, 也可以一開一關, 取代了傳統管路中多個閥門串聯的複雜形式, 減少洩露點, 節省空間。

◇ 閥門防火(API607/API6FA)、防靜電

◇ 閥杆防吹出

◇ 自動洩壓功能: 當閥門中腔滞留的介質壓力異常升高(超過彈簧預緊力)時, 閥座後退脫離球體, 自動洩壓。

◇ 雙阻塞雙排放功能: 閥門采用彈簧預緊浮動閥座, 閥門全開或全關時, 球前球後閥座均能阻斷流體, 中腔壓力通過洩放閥洩放。

◇ 密封緊急注脂救護功能: 因介質中的異物或火災等原因造成閥門密封意外失效時, 可以通過閥杆注脂器和閥座注脂器快捷地将密封脂注入到閥門密封部位, 緩解洩露。

◇ 閥門工作時, 閥前流體壓力在球體上産生的作用力全部傳遞給軸承, 閥座不會承受過大的壓力, 使得閥門轉矩小、閥座變形小、密封性能穩定、使用壽命長。
