Elastic seat seal gate valve

Gate valve refers to a gate-shaped valve used to cut off and regulate flow. It is installed on the outlet pipeline of centrifugal pumps and mixed flow pumps.The nominal pressure of the gate valve is PN0.1~32; the nominal diameter is DN15~1800; the operating temperature t≤550℃.It has the characteristics of small fluid resistance and small opening and closing torque, and is divided into rigid gate valve and elastic gate valve.Its function is to close the valve before starting the water pump, and use the vacuum pump to pump air and fill it with water; closing the valve when the centrifugal pump starts can reduce the power of the power machine.It is used to connect and cut off the medium in the pipeline.The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, but cannot be adjusted or throttled.The gate valve is sealed through the contact between the valve seat and the gate plate.
