[0002] Early air conditioning systems were mostly cooling-only. With increasing demands for improved living comfort and a growing demand for dual-purpose air conditioners, a four-way valve, capable of conveniently switching between cooling and heating modes, was developed and implemented in air conditioning systems. This component controls the flow of refrigerant, alternating the direction of the compressor's exhaust and return lines into the evaporator and condenser, enabling the transition between cooling and heating.

[0003] The four-way valve component is the core component of the air-conditioning outdoor unit, and is mainly composed of the valve body, suction pipe, exhaust pipe, cooler connecting pipe and valve connecting pipe welded together. Due to the structural differences in the outdoor unit pipelines of different models, the angles when welding the four-way valve to the suction, exhaust, cooler and valve pipes are also different. Before welding, tooling positioning is required to ensure accuracy, resulting in the need to frequently replace positioning tooling at the welding position, which is time-consuming and labor-intensive, not only not conducive to ensuring work efficiency, but also not conducive to cost control. In addition, the valve core material of the four-way valve is not resistant to high temperatures. In order to prevent the valve core of the four-way valve from being deformed by heat during welding, the four-way valve needs to be immersed in water for protection, and a suitable container needs to be selected for cooling, which is not conducive to cost control.
