[0015] see figure 1 . The present invention will be further illustrated in the following examples, which are only used to illustrate the present invention and not to limit the present invention.
[0016] Preparation before welding. Use mechanical methods to remove the oxides on the surface of the joints of the parts, and use the organic cleaning agent acetone to clean the joints near the joints to be welded strictly before welding. The rigid fixing method is used to fit the valve seat and the gasket tightly into the fixture, "eight-point symmetry, bolt fastening", and the pre-tightening force is adjusted by the thread. The shrinkage of the shaft and diameter after welding is controlled by "side top pressure" to reduce angular deformation and bending deformation, thereby controlling the coaxiality of the valve seat and gasket, and ensuring the sealing effect of the valve body assembly to the greatest extent.
