Abstract

The invention provides a welding tool for a four-way valve of an air conditioner, and can solve the problems in the prior art that the four-way valve tube bank can not be positioned in the welding process and nitrogen filling protection can not be realized. The invention adopts the technical proposal that the four-way valve welding tool for the air conditioner comprises a water tank, a four-way valve welding device is arranged in the water tank, is used for positioning the four-way valve when being welded with the associated pipe, and comprises a fixing plate, V-shaped iron for positioning the four-way valve and a long groove for the tubule of the four-way valve to penetrate are arranged on the fixing plate, and a V-shaped groove A for positioning the pilot valve on the four-way valve is arranged on one side of the long groove. The four-way valve welding tool has the advantages that the four-way valve tube bank can be positioned accurately, nitrogen filling protection is always provided to the tube bank in the welding process, the welding efficiency and the welding quality of the air conditioner product line can be enhanced, and the performance of the entire air conditioner can be improved, so as to lead the product to be more competitive.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning processing technology, and relates to a four-way valve welding tool in an air-conditioner refrigeration system, in particular to an air-conditioner four-way valve welding tool. Background technique [0002] The cooling and heating heat pump room air conditioner performs cooling and heating conversion through the four-way valve of the outdoor unit. The welding quality of the four-way valve of the outdoor unit directly affects the efficiency, noise and piping vibration of the whole machine. [0003] The traditional four-way valve welding of the outdoor unit generally uses simple welding equipment and a water tank for welding. The shape of the four-way valve pipe group of the outdoor unit is randomly broken by hand, and it cannot be positioned, resulting in vibration and noise caused by the collision of the four-way valve pipe group. The air conditioner processing technology requires that th...
