Principle of knife gate valve

The knife gate valve mainly consists of three parts, namely, the control hand wheel of the knife gate valve, the outer wall of the valve body and the internal control device.We use the knife gate valve mainly through the control of the handwheel on the knife gate valve easy to operate, so that the control device inside the valve body for a series of physical movement, and finally form the valve opening and closing, so that the knife gate valve can carry on the normal work, control the pipe on and off.

The internal structure of knife gate valve is very complex, we turn the knife gate valve handwheel by hand, to make it happen, this can make the knife gate valve affects the inside of the knife gate valve lever and gear, after linkage type of movement, to make the inside of the valve block device is changing rapidly, according to different rotation direction to make knife gate valve opening and closing.Moreover, such work can be completed in a very short time, which can effectively save time and improve work efficiency.

Knife gate valve service range:

1. Mining, coal washing and iron and steel industry -- used for coal washing pipelines, filter slurry pipelines and ash discharging pipelines;

2. Purification plant -- for waste water, mud, dirt and clear water with suspended matter;

3. Paper industry -- used in pulp and water mixtures of any concentration;

4. Power station ash removal -- used for ash slurry.
