Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a multi-point welding tooling for a four-way valve of an air conditioner. Background Art

[0002] A four-way valve is a control valve with four openings. Most of the existing air-conditioning four-way valves are connected to the pipeline by welding. However, when welding, the four-way valve and the pipeline need to be fixed. Since the four-way valve and the pipeline are mostly made of metal materials with good thermal conductivity, they are usually clamped with pliers, which requires the cooperation of multiple people, resulting in troublesome welding. In addition, in order to protect the four-way valve, it is usually necessary to cool the four-way valve during welding. Most of the existing cooling methods are to lay a towel on the four-way valve and then cool it by pouring water. It is easy for water to splash onto the welding point, resulting in a decrease in the temperature of the welding point, thereby affecting the welding quality.

[0003] To this end, the utility model provides a multi-point welding tool for an air-conditioning four-way valve. Utility Model Content

[0023] Specifically, when welding is performed, the four-way valve is clamped and fixed by the upper clamp 1 and the lower clamp 2, and then water is added to the first water tank 3 through the water inlet 5, so that the water flows into the second water tank 4 and then flows out from the water outlet 6, so that the four-way valve can be cooled by heat exchange, and at the same time, the sponge cloth 7 absorbs water, and the sponge cloth 7 directly contacts the four-way valve, so that the water absorbed by the sponge cloth 7 directly contacts the four-way valve, thereby improving the cooling effect and preventing the four-way valve from being damaged.
