During use, chips may enter the air cavity of the existing mixing chamber, which is not convenient for protecting the pores. At the same time, welding leaks and nodules are prone to occur inside the cavity. Summary of the invention

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The inner shell and the outer shell of the present invention are connected by vacuum brazing. After welding, the two end faces and the inner cavity profile are precision-turned. When processing the end faces, the copper is used as the reference to symmetrically remove the excess at both ends. When processing the inner cavity, a temporary rubber plug is used to protect the pores to prevent chips from entering the air cavity.

[0009] After the inner shell and outer shell assembly welding and finishing are completed, the gas and water pipelines are welded by argon arc welding. The position relationship of the pipelines and joints refers to the three-dimensional digital model. The height of the weld legs at each location shall not be less than the wall thickness of the pipeline, and no welding leakage or nodules shall be generated inside the cavity;

[0010] After the overall manufacturing is completed, the cooling water cavity is subjected to a 6MPa water pressure test and the pressure is maintained for 30 minutes. The pressure gauge does not drop in pressure, and the product is qualified if there is no leakage, obvious deformation, or damage. The air cavity is also subjected to a corresponding airtightness test to ensure that the air path weld is sealed reliably. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Working principle: the inner shell 4 and the outer shell 1 are connected by vacuum brazing. After welding, the two end faces and the inner cavity profile are precision-turned. When processing the end faces, the copper is used as the reference to remove the excess symmetrically at both ends. When processing the inner cavity, a temporary rubber plug is used to protect the pores to prevent chips from entering the air cavity. After the inner shell 4 and the outer shell 1 are welded and precision-turned, the gas and water pipelines are welded by argon arc. The position relationship of the pipeline and the joint refers to the three-dimensional digital model. The height of the weld feet at each location is not less than the wall thickness of the pipeline, and no welding leakage and nodules shall be generated inside the cavity. After the overall manufacturing is completed, the cooling water cavity is subjected to a 6MPa water pressure test, and the pressure is maintained for 30 minutes. The pressure gauge does not reduce the pressure. The product has no leakage, no obvious deformation, and no damage, which means it is qualified. The corresponding air tightness test is also carried out on the air cavity to ensure that the gas path weld is sealed reliably.

[0021] The first flange 2, the second flange 3 and the outer shell 1 are welded by argon arc welding. The effective depth of the weld leg is not less than 10mm. There must be no internal defects such as pores and slag inclusions. The weld must be tested by surface coloring and meet Class I qualification. The parts are degreased after processing. The material of the inner shell 4 is oxygen-free copper forgings, and the quality must meet the relevant mechanical performance requirements and nondestructive testing requirements.
