Flow regulating valve manufacturing process

Abstract

The invention relates to a flow regulating valve manufacturing process which uses flow regulating valve manufacturing equipment. The flow regulating valve manufacturing equipment comprises a base andan auxiliary device, and the auxiliary device is arranged on the upper surface of the base. The process can solve the problems existing in anti-corrosion treatment conducted after flow regulating valve bodies are manufactured at present: the valve bodies are directly placed in anti-corrosion liquid for anti-corrosion treatment, so that the whole valve bodies can be in contact with the anti-corrosion liquid, when the valve bodies are in use practically, the place, treated by the anti-corrosion liquid, inside the valve bodies can be directly in contact with water, the problem that residual anti-corrosion liquid pollutes the water bodies is easily caused, when the flow regulating valve bodies are subjected to anti-corrosion treatment, the valve bodies are subjected to anti-corrosion treatmentat the same time or one by one, when the valve bodies are taken out in the earlier mode, anti-corrosion treatment time of some valve bodies is different, the problem of valve body damage is caused due to the too long time of anti-corrosion treatment, and the anti-corrosion treatment efficiency of the valve bodies is reduced in the later mode.

Description

technical field [0001] The invention relates to the field of valve production, in particular to a flow regulating valve manufacturing process. Background technique [0002] The flow regulating valve is an intuitive and simple flow regulating control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the residual pressure head of the pipeline and the pressure caused by the pressure fluctuation under the action of water. Flow deviation, no matter how the system pressure changes, the set flow rate remains unchanged. These functions of the valve enable the flow adjustment of the pipe network to be completed at one time, turning the network adjustment work into a simple flow distribution, effectively solving the hydraulic imbalance of the pipe network; flow adjustment The valve is mainly used in: central heating / cooling water systems, so that the flow of the pipe network can be di...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the anti-corrosion treatment of the flow regulating valve body after manufacture: when the existing anti-corrosion treatment is performed on the flow regulating valve body, the valve body is directly placed in the anti-corrosion liquid for anti-corrosion treatment, so that the entire valve body It will not come into contact with the anti-corrosion liquid. When the valve body is actually used, the part inside that has been treated with anti-corrosion liquid will be in direct contact with the water body, which will easily cause the problem of residual anti-corrosion liquid polluting the water body, and it is necessary to adjust the flow rate produced. When the valve body is subjected to anti-corrosion treatment, multiple valve bodies are placed in the anti-corrosion liquid at one time for anti-corrosion treatment or one by one. When the former is taken out of the valve body, the anti-corrosion treatment time of some valve bodies will vary. Excessive anti-corrosion will cause damage to the valve body, which will reduce the anti-corrosion treatment efficiency of the valve body
