Knife gate valve, additionally called knife kind gate valve, is a kind of gate valve. The architectural attribute of the knife gate valve is that there is an oblique cut at the bottom of its valve plate. Like a knife edge, this knife-shaped oblique cut can conveniently cut off the medium distributing in the pipe, so that the valve can be shut without being obstructed by the tool. Below is the structure representation of the knife gate shutoff.

Knife gate valves are generally utilized in medium pipelines such as pulp, slag, coal ash, sewage, as well as chemical raw materials. They can just be totally opened up and completely closed. They are used as shut-off valves and can not be utilized for flow law. The transmission settings of the knife gate valve are hands-on, pneumatically-driven, electrical, and so on, as well as its functioning principle is also very easy. The adhering to takes the manual knife door valve as an instance to present the working concept of the knife gate valve to you.

The functioning concept of the hands-on knife gate valve is to turn the handwheel by hand to make the valve stem surge or loss, therefore driving the gate to go up as well as down to achieve the purpose of opening or shutting the valve. Transform the handwheel clockwise, eviction decreases, as well as the valve closes. Turn the handwheel counterclockwise, the gate rises, as well as the valve opens up.

Compared with the conventional gate valve, the structure of the knife gate valve is less complex, the length as well as size are smaller sized, and also it is less complicated to set up, take apart and also maintain. Knife gate valves are suitable for use in tool pipes with high consistency and solid bits. Eviction like a guillotine has a better gate splitting result, and can efficiently cut off various pollutants included in the medium in the pipeline, entirely resolving the leakage phenomenon of the standard gate valve after passing through the medium containing particulate contaminations.
