The structural characteristics of the slurry valve are: the left and right valve bodies are separated, with a valve seat sandwiched between the two valve bodies. The valve seat can be replaced by removing the bolts connecting the two valve bodies; The inner cavity of the valve body is equipped with a protective plate that is resistant to erosion and corrosion. When the valve is opened, it can protect the valve body from being eroded and corroded by the medium, and the entire body is chemically plated with Ni P treatment achieves 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. Spherical sealing is used between the sealing pairs to ensure that the sealing surface is in line contact, ensuring the reliability of the seal and preventing scarring. The valve is equipped with an upper sealing structure, which can protect the packing when fully opened. 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.
