DSJ41H/Y水封閘閥設(shè)計特點：
- 水封截止閥按國家標準GB12235設(shè)計制造，結(jié)構(gòu)新穎，選材合理,造形美觀。連接端有法蘭和焊接，可根據(jù)用戶不同要求配接。
- 填料函設(shè)計成水密封結(jié)構(gòu)，接入0.6~1.6Mpa的水填料，摩擦力小，密封好，能全系統(tǒng)與大氣隔離，保證良好的氣密性。
- 閥桿經(jīng)調(diào)質(zhì)和表面氮化處理，有良好的搞腐蝕性和抗擦傷性。
- 結(jié)構(gòu)緊湊，操作靈活，檢修方便，使用壽命長。
- 倒密封采用不銹鋼螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，倒密封可靠。填料更換和維修可在不停機情況下進行，方便快捷不影響系統(tǒng)運行。
