Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Taking copper pipe as an example, the preferred embodiment of the present invention will be described in detail. Obviously, pipes made of other ductile materials are also suitable for the present invention, such as plastic pipes, zinc alloy pipes, aluminum alloy pipes, etc.

[0028] Such as Figure 1-6 As shown, a pipe terminal sealing structure includes a steel ring 2 , an intermediate body 3 , a gasket 4 and a sealing plug 5 . The intermediate body 3 is a cavity with one end sealed. The inner side of the sealed end is provided with a positioning groove 31. The intermediate body...

Abstract

The invention discloses a pipe terminal sealing structure and a method for assembling the structure and the pipe, including a steel ring, an intermediate body and a washer, wherein the steel ring includes a connecting portion and a limiting portion, and the intermediate body is provided with the shape and shape of the outer wall of the pipe. Blind holes with matching sizes, the intermediate body and the limiting part can be sleeved on the outer wall of the pipe, the connecting part is sleeved on the outer wall of the blind hole opening end of the intermediate body, and the connecting part and the outer wall of the intermediate body are interference fit; the gasket is set on The inside of the steel ring is in contact with the inner end surface of the limiting part, the gasket can be sleeved on the outer wall of the pipeline, and the outer surface of the gasket is in interference fit with the inner wall of the blind hole of the intermediate body. During the assembly process of the structure and the pipeline, two plastic deformation zones will be formed on the pipeline, and the formation of the deformation zone provides the strength and sealing required for the plugging. Compared with the existing cold working method for sealing pipelines, the invention can complete the sealing of pipelines without adding any filler, thereby more effectively preventing pipeline leakage.

Description

technical field [0001] The invention relates to the improvement of a pipeline sealing device in a refrigeration system, in particular to a pipeline terminal sealing structure and a method for assembling the structure and pipelines. Background technique [0002] The pipe sealing device is installed at the end of the pipe, which is a kind of mechanical fastener. Its function is to seal the pipe, and it is used to block the unnecessary opening in the pipe and play a sealing role. [0003] In recent years, due to the demand for environmental protection, the refrigerant in the refrigeration system has been replaced by alkanes, such as R290, R32, etc., which are flammable and explosive. After the factory uses this type of refrigerant, it often uses a stop valve to reverse the refrigerant. The production efficiency of the method is low, and the cost is high. [0004] At present, there is another cold processing method on the market. Patent No. CN201920382158.8 proposes a sealing d...
