Gas welding protection device for welding refrigeration system components

Abstract

The invention provides a gas welding protection device used for welding parts of a refrigerating system. The gas welding production device is characterized by comprising a welding die, wherein the welding die is provided with a gas injection port and at least one positioning slot used for accommodating the welded parts of the refrigerating system, a gas pipeline through which protective gas flowsis arranged in the welding die, one end of the gas pipeline is connected with the gas injection port, the other end of the gas pipeline is connected with the welded parts used for the refrigerating system, and sealing structures are arranged at the positions where the gas pipeline is connected with the parts used for the refrigerating system. The gas welding protection has a simple structure, doesnot take up additional space, does not use or reduce pickling treatment, effectively reduces the cost of an enterprise and reduces the harm of toxic and harmful dangerous chemicals, plays the effectsof energy saving, emission reduction and environmental protection, and does not affect the technical requirements of a product.

Description

technical field [0001] The invention relates to the technical field of protective welding of refrigeration system components, in particular to a gas welding protection device for welding refrigeration system components. Background technique [0002] At present, in the refrigeration industry, for example, the parts used in air-conditioning systems are usually flame-welded, and then used directly or after pickling before production. Once the parts that are directly used in the air conditioning system after flame welding produce oxides, it may block the pipeline, which will affect the entire system and cause the failure of the entire air conditioning unit. However, the cost of pickling treatment is high. In order to reduce the pressure brought by production costs, some enterprises will directly adopt the method of straight row and sneak discharge for subsequent treatment. This treatment method will pollute the environment, destroy the ecological balance, and leave immeasurable ...

Problems solved by technology

Once the parts that are directly used in the air conditioning system after flame welding produce oxides, it may block the pipeline, which will affect the entire system and cause the failure of the entire air conditioning unit.

However, the cost of pickling treatment is high. In order to reduce the pressure brought by production costs, some enterprises will directly adopt the method of straight row and sneak discharge for subsequent treatment. This treatment method will pollute the environment, destroy the ecological balance, and leave immeasurable infinite future trouble
