Abstract

The invention discloses a welding protection device, which belongs to the technical field of welding. The welding protection device includes a shell, the shell is a hollow structure, the inner cavity of the shell is used to place the valve body of the electronic expansion valve, a moisturizing part is arranged in the inner cavity of the shell, and a cooling hole is opened on the shell. The invention can solve the problem of poor heat dissipation and cooling effect of the welding cooling protection device of the electronic expansion valve. When welding the electronic expansion valve, the valve body of the electronic expansion valve is placed in the inner cavity of the housing of the welding protection device. The moisturizing part is used to cool down, and at the same time, by opening cooling holes on the shell of the welding protection device, the effect of evaporation and heat dissipation can be improved, avoiding the accumulation of heat during the welding process, and reducing the impact on the welding effect.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding protection device. Background technique [0002] Among the four major components of the air-conditioning system, the throttling components play a very important role. Its good control affects the performance of the air-conditioning. At present, the throttling components used in the air-conditioning system include electronic expansion valves and solenoid valves. The valve body of the electronic expansion valve is in Overheating protection is required during welding to ensure the quality of welding. The welding cooling protection device of the electronic expansion valve in the prior art adopts heat-insulating and heat-absorbing materials inside the device, but because the flame temperature is as high as several hundred degrees during welding, it is easy to accumulate heat, and the heat dissipation and cooling effect is relatively poor, which affects welding. Effect. Co...
