[0002] Double-inserted plate valve is a kind of valve for controlling medium flow in pipeline, usually applied in occasions requiring reliable closing and opening operation. The valve is characterized by having two parallel valve plates (also known as gate plates) that can move up and down within the valve body. When both valve plates move up simultaneously, medium can pass through; when the valve plates move down and tightly contact with the valve seat, complete blockage of medium flow can be achieved.

[0003] If the medium contains large particles or other impurities during the use of the existing double-inserted plate valve, these substances will be stuck between the valve plate and the valve seat, affecting the sealing effect and even causing damage. In suitable application scenarios, the service life of the double-inserted plate valve is usually one to two years.
