The discharge valve has two structural forms: Y-shaped and angular. According to the actual working conditions, the discharge port is designed in two forms: with pipe connection and flat bottom. The valve body is equipped with a protective plate that is resistant to erosion and corrosion. At the moment of opening the valve, it can protect the valve body from being eroded and corroded by the medium, and the entire body is chemically plated with Ni. P to achieve a surface hardness of HRC60-62, with excellent functions of high wear resistance and corrosion resistance. The sealing surface of the valve seat and the sealing surface of the valve disc are both welded with Stellite hard alloy, and the sealing pair adopts line sealing to ensure sealing, reliability, and prevent scarring. The valve is equipped with an anti rotation mechanism to ensure that the valve stem only moves in a straight line and does not rotate during opening and closing.
The valve drive methods include manual, electric, pneumatic, and gear transmission.
