Problems solved by technology

However, the existing conversion joints have a low service life, and are usually directly processed from thin steel pipes. The pipe wall is thin, resulting in shallow threads at the joints, which is very easy to cause loosening of the sliding wire, and the conversion joint is easily deformed due to the thin pipe wall. Even broken, thus destroying the sealing of the valve joints and pipeline connections of each equipment, resulting in leakage of refrigerant

Abstract

The invention provides a high-strength conversion joint for refrigeration equipment. The high-strength conversion joint is of a hollow tubular structure and comprises an internal connection end and anexternal connection end which are integrally connected, an inner thread is arranged on the inner wall of the internal connection end, an outer thread is arranged on the outer wall of the external connection end, and an annular groove is formed in the spliced position of the internal connection end and the external connection end. According to the high-strength conversion joint for the refrigeration equipment, on the one hand, the connection strength between a valve joint and a pipeline joint is improved, the service life of the conversion joint is prolonged, on the other hand, connection tightness and airtightness are ensured, and thus a refrigerant is prevented from leaking out.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a high-strength conversion joint for refrigeration equipment. Background technique [0002] Refrigeration equipment refers to equipment mainly used for food refrigeration, refrigeration of various goods and indoor air conditioning in summer. It is mainly composed of compressor, expansion valve, evaporator, condenser, accessories and pipelines. During the layout and installation of refrigeration equipment, various parts are mainly connected through different pipelines to ensure the flow of refrigerant. The connection between the pipeline and the valve joint needs to ensure tightness, otherwise it is easy to cause the refrigerant to overflow and cause waste of refrigerant. In the prior art, due to the different inner diameters of the joints between the valve joints and the pipeline joints, it is impossible to directly realize the airtight connection. At present, ...
