RETZ瑞茨『進口鍛鋼截止閥』詳細介紹●RETZ截止閥系列●RETZ鍛鋼截止閥●產品數據
?進口鍛鋼截止閥描述--
RETZ鍛鋼截止閥的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質流通。截止閥只許介質單向流動，安裝時有方向性
The closing principle of RETZ forged steel cut-off valve is that the valve sealing surface and valve seat sealing surface are closely linked by the pressure of the valve bar to prevent the flow of medium. The shut-off valve only allows one-way flow of medium and has directivity when installed.
?進口鍛鋼截止閥特征--
全徑或縮徑,明桿支架式
整體式閥體或焊接式體
閥瓣可變換為節(jié)流型、針型、球型和止回型
閥體和零件全部鍛鋼更加堅固,可耐高溫高壓
閥桿行程短,啟閉迅速
Full diameter or shrinkage
Integral body or welded body
The disc can be changed into throttling, pin, ball and check type.
All valves and parts are forged steel more sturdy, resistant to high temperature and high pressure.
Short stem stroke, quick opening and closing
?進口鍛鋼截止閥結構--
鍛鋼截止閥有三種蓋設計形式。
1.*種是螺栓式閥蓋，按這種設計形式設計的閥門，其閥體與閥蓋用螺栓螺母連接，纏繞式墊片（316夾柔性石墨制造）密封?？蛻粲刑厥庖髸r也可采用金屬環(huán)連接。
2.第二種設計形式是焊接式閥蓋，按這種設計形式的閥門，其閥體與閥蓋用螺紋連接，全焊密封?？蛻粲刑厥庖髸r也可采用全焊透連接。
3.第三種是壓力自緊式閥蓋，按這種設計形式設計的閥門，其閥體與閥蓋用螺紋連接，內壓自密環(huán)密封。
