暗杆式电动刀闸阀
dark rod electric knife gate valve
暗杆式电动刀闸阀是闸板埋在阀体内腔*与外界环境隔绝的一种阀门，它适合与那些安装在污水池底下阀体浸泡在液体里的管道，如果不把闸板与外界环境隔离，那么闸板就很快会被外界环境所腐蚀，影响了阀门使用寿命。其密封结构是通过闸板关闭下移直到闸板底部斜面与阀体下锲块压紧使得闸板贴紧阀座密封面，从而达到了密封效果。此阀门配备伞齿轮操作启闭轻松灵活；此阀门适用于水利工程、地下管道工程等领域。该阀门配电动执行器可实现远程微电脑控制。在电源供应中断时，也可以通过手动来操作阀门启闭，从而紧急控制了介质的流向，也避免了事故的发生。也可以使用现场电控箱、远程PLC电动智能控制等附件来操作和调试的控制。用户可根据实际需要进行选择。
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.
