暗桿式電動刀閘閥
dark rod electric knife gate valve
暗桿式電動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。該閥門配電動執行器可實現遠程微電腦控制。在電源供應中斷時，也可以通過手動來操作閥門啟閉，從而緊急控制了介質的流向，也避免了事故的發生。也可以使用現場電控箱、遠程PLC電動智能控制等附件來操作和調試的控制。用戶可根據實際需要進行選擇。
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. It can remote control for equipping with electric actuator . When power is cut off ,it also can be operated by manual to control the flow of media an avoid accidents . You can also use electric control box, remote PLC inligent control ,etc,to operate and debug control. Users can choose according to the their needs.
