dark rod bevel gear knife gate valve

暗桿式傘齒輪刀閘閥是閘板埋在閥體內腔*與外界環境隔絕的一種閥門，它適合與那些安裝在污水池底下閥體浸泡在液體里的管道，如果不把閘板與外界環境隔離，那么閘板就很快會被外界環境所腐蝕，影響了閥門使用壽命。其密封結構是通過閘板關閉下移直到閘板底部斜面與閥體下鍥塊壓緊使得閘板貼緊閥座密封面，從而達到了密封效果。此閥門配備傘齒輪操作啟閉輕松靈活；此閥門適用于水利工程、地下管道工程等領域。與傘齒輪輔助配合，達到很輕便的啟閉效果，此閥主要用于現代工業領域上。

Dark rod knife gate valve with disc buried in the body cavity is compley isolated from the external environment, it is suitable for pip which is installed in the swage pool and body is immersed in the liquid . If disc is not isolated from external environment ,disc will be corrupted immediay , so it will affects life of the valve. The seal structure is that gate moves down till the bottom of the ramp compress carve blocks of the body to make gate compresses the sealing of the seat to achieve sealing effect. Equipped with bevel gear ,it's easy to to open and close .This kind of valve is suitable for water conservancy ,underground pipe engineering ,etc. Assisted with bevel gear ,it's easy to open and close. This kind of valve is mainly used in modern industry field.
