Embodiment Construction

[0050] This embodiment provides a method for sealing pipelines of a refrigeration system, wherein the refrigeration system is a refrigeration system of refrigeration equipment, and the refrigeration equipment can be refrigerators, freezers and other equipment with refrigeration and / or freezing functions.

[0051] The pipeline therein may include an inner cannula 200 and an outer cannula 100. The inner cannula 200 is inserted into the outer cannula 100 and docked with the outer cannula 100. In order to seal the joint between the inner cannula 200 and the outer cannula 100, this embodiment A new type of sealing device is used to seal the joint. Wherein, the butt joint can be the position where the end of the outer tube 100 and the inner cannula 200 butt and the inner cannula 200 overlap.

[0052] Such as figure 1 As shown, the sealing method may specifically include:

[0053] Step S102, inserting the inner cannula 200 into the outer cannula 100 to connect the two;

[0054] St...

Abstract

The invention provides a sealing method of a refrigerating system pipeline. The pipeline comprises an inner insertion pipe and an outer sleeve pipe. The sealing method comprises the steps of insertingthe inner insertion pipe into the outer sleeve pipe to connect the inner insertion pipe with the outer sleeve pipe; wrapping the joint between the outer sleeve pipe and the inner insertion pipe through a sealing device; and filling sealant into a sealant storage cavity of the sealing device through a sealant filling port in the sealing device. The pipeline is sealed through the sealing device andthe sealant. A lot of problems caused by flame brazing for an existing refrigerator are avoided. Operation is safe. The sealing process is simplified. Standardized execution is facilitated. Moreover,the pipeline is wrapped through the sealing device first, and then the sealant is filled to carry out sealing on the pipeline. The sealing effect is better.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for sealing pipelines of a refrigeration system. Background technique [0002] Existing refrigerators generally use vapor compression refrigeration. The refrigeration system generally includes compressors, condensers, capillary tubes, evaporators, etc., which are connected by pipelines to form a sealed system. The refrigerant undergoes a phase change inside to release heat and absorb heat. heat, and cool. For the entire refrigeration system, the sealing is particularly important. Once the refrigerant leaks, it will not only affect the refrigeration performance, but also most of the flammable refrigerants used now will bring certain safety hazards. [0003] The sealing of existing refrigeration system pipelines generally adopts the mode of flame brazing. Flame brazing has strict requirements on the operating level of the operators, and the production line g...
