Product Description

The knife gate valve mainly includes three parts, namely, the control handwheel of the knife gate valve, the outer wall of the valve body and the internal control device. We use the knife gate valve mainly by manipulating the handwheel on the knife gate valve, which is easy to operate, so that the control device inside the valve body carries out a series of physical movements, and finally the valve is opened and closed, so that the knife gate valve can work normally and control the on-off of the pipeline.Knife gate valve, also known as knife gate valve and knife gate valve, is suitable for pipelines with suspended particles, pulp with fiber materials, sewage, coal slurry, ash cement mixture and other media, and these media are cut off by blade gate that can cut fiber materials. In fact, there is no cavity in the valve body, and the gate moves up and down in the side guide groove, and is pressed against the valve seat by the lug at the bottom. If high medium tightness is needed, the O-shaped sealing valve seat can be selected to realize bidirectional sealing. According to the driving mode, it is divided into manual knife gate valve, pneumatic knife gate valve and electric knife gate valve. The gate of knife gate valve has shearing function, which can scrape off the adhesive on the sealing surface and automatically remove impurities. Stainless steel gate can prevent seal leakage caused by corrosion.
