Problems solved by technology

During the processing of the above-mentioned ball valve, it is necessary to weld and fix the valve body 1 and the first copper connecting pipe 3, the valve cover 2 and the second copper connecting pipe 4, and then screw the valve body 1 and the valve cover 2, So as to form a whole, while the traditional welding method adopts the manual welding method, the labor intensity is relatively high, and only one workpiece can be welded at a time, the whole welding process cannot realize continuous production, and the work efficiency is not high. , during manual welding, the quality of welding will be artificially affected, and the welding quality is unstable

Embodiment Construction

[0040] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0041] The ball valve includes a valve body and a valve cover that cooperate with each other. The valve body and the valve cover are fixed by threads. A first copper pipe is connected to the side of the valve body away from the valve cover. The second copper connecting pipe, the valve body, the valve cover, the first copper connecting pipe and the second copper connecting pipe cooperate together to form a path for fluid flow.

[0042] The processing method for the refrigeration system ball valve of the present invention is realized through the following steps:

[0043] The first step, feeding: First, send the processed copper pipe, valve body and valve cover to the special welding system for standby.

[0044] Such as Figure 2-Figure 7 The schematic diagram shown shows th...

Abstract

The invention relates to a processing method for a ball valve in a refrigeration system, comprising the following steps: firstly, sending the processed copper connecting pipe, valve body and valve cover into a special welding system for standby; The valve body and valve cover are preheated. After the preheating is over, the welding torch and the flame nozzle are used for welding. After the welding is completed, three cooling water pipes are used to spray cooling water to gradually cool the welding place. The cooled workpiece is taken out manually, and the welding of the valve body, valve cover and copper connection pipe is completed. The advantage of the present invention is that: the processing method of the present invention is based on a special welding system, and then cooperates with the temperature and time of preheating, and the temperature and time of welding, so as to improve the welding quality and ensure the stability of welding. The temperature and other parameters are controlled, so that the welding place can be cooled rapidly, and the welding place will not be affected by the rapid cooling, so as to ensure the quality of welding.

Description

technical field [0001] The invention relates to the field of refrigeration unit processing, in particular to a processing method for a refrigeration system ball valve. Background technique [0002] A system that uses external energy to transfer heat from a lower-temperature substance (or environment) to a higher-temperature substance (or environment) is called a refrigeration system. The refrigeration system consists of a refrigerant and four major components, namely a compressor, a condenser, Expansion valve, evaporator. [0003] The compressor is the driving force of the refrigeration cycle. It is driven by the motor and rotates continuously. In addition to timely extracting the vapor in the evaporator to maintain low temperature and low pressure, it also increases the pressure and temperature of the refrigerant vapor through compression to create a refrigerant. The condition under which the heat of vapor is transferred to the external environment medium. That is, the lo...
