After the seam is welded, the DIN Ball Valve Body is free from deformation, including the upper and lower shaft flanges.
The heating area of the valve body should not be too wide and the temperature should not be too high, otherwise the sealing device inside the valve body will be destroyed.
No welds can occur.
Ensure that the pressure is above 10MPa.
Weld structure
According to the above technical requirements, it is determined that the weld is not welded through the weld. Therefore, the butt joint form of the weld is required to ensure both assembly and penetration. After testing, the form of the weld is finally determined.
Body material in DIN Ball Valve Body Supplier
The chemical composition of the valve body is tested before processing, and the test results are consistent with the test results at the time of casting, which meets the design requirements.
assembly
The hydraulic tire is used to modify the position of the reversing tire, and the two halves are fastened with bolts to adjust the sealing test, and the design between the outer part of the sphere and the valve body is achieved.
