德國奧萊斯OLES進口鍛鋼閘閥
【進口鍛鋼閘閥】詳細說明:
鍛鋼閘閥有三種閥蓋設計,*種是螺栓型閥蓋,通過凹凸面連接,采用不銹鋼帶與柔性石墨纏繞墊片,按需求也可采用環連接,第二種是焊接型閥蓋,通過螺紋密封后焊接,按需求也可直接采用剛性焊接,第三種是自密封閥蓋,通過螺紋與自密封閥蓋連接.
Forged steel gate valve has three kinds of cover design, the first is bolt-type cover, through concave and convex connection, using stainless steel belt and flexible graphite winding gasket, according to demand can also be used ring connection, the second is welded valve cover, through threaded seal after welding, according to demand can also be directly used rigid welding, the third is self-sealing valve. The cover is connected with the self-sealing valve cover by threads.
【進口鍛鋼閘閥】特點:
1、結構緊湊、造型美觀、縮徑流道。結構特征:B.B或W.B;
2、密封面采用合金鋼或硬質合金,密封副材料配對合理,使用壽命長。
3、閘板結構型式為:剛性楔形單閘板。閥桿表面經氮化處理,具有良好的抗腐蝕性、抗摩擦性。 填料采用柔性石墨,密封可靠,操作靈活,啟閉力矩小。
4、可選用各種配管標準及連接形式(如:承插焊、對焊、螺紋連接)
【進口鍛鋼閘閥】結構說明:
鍛鋼閘閥有三種體蓋連接設計結構形式。*種是體蓋螺栓連接鍛鋼閘閥,按這種連接形式設計的閥門,其閥體與閥蓋用螺栓連接,纏繞式墊片密封,優點是便于維修。第二種體蓋焊接連接鍛鋼閘閥,按這種連接形式設計的閥門,其閥體與閥蓋全焊密封,優點是無外泄漏。第三種是壓力自緊式閥蓋鍛鋼閘閥,按這種連接形式設計的閥門,其閥體與閥蓋用螺蚊連接,內壓自密封環密封,優點是內部壓力越大,其密封性能越好。您可以根據實際情況合理選用閥門
