Description

A distributor for a refrigeration system Technical Field

[0001] This utility model belongs to the field of refrigeration technology, and in particular relates to a distributor for a refrigeration system. Background Technology

[0002] Currently, most distributors in general refrigeration systems are made of brass. For example, a U-shaped body is cold-forged from a copper column, and an imported copper connector is welded to the opening of the U-shaped body. A diversion copper connector is welded to the through hole at the bottom of the U-shaped body. Its disadvantages are: high cost, low strength, easy deformation, poor corrosion resistance, resulting in short service life and high maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide a distributor for refrigeration systems that is low in cost, high in strength, not easily deformed, has good corrosion resistance, long service life, and low maintenance cost.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A distributor for a refrigeration system includes a straight pipe section and a necked connector disposed at an opening at one end of the straight pipe section. The straight pipe section is made of stainless steel, and a stainless steel plate or copper plate is welded to the other end of the straight pipe section. A diversion copper connector is welded to two or more through holes provided on the stainless steel plate or copper plate. Alternatively, the straight pipe section and the other end of the straight pipe section are an integral structure formed by cold forging or stamping of stainless steel sheet. A diversion copper connector is welded to a through hole provided on the base plate of the integral structure. A snap-fit ​​part is provided on the inner wall of the straight pipe section, and a filter screen is snapped onto the snap-fit ​​part.

[0006] As a further optimization of the above technical solution, the necked connection is formed by spinning one end of a straight tube made of stainless steel.

[0007] As a further optimization of the above technical solution, the necked connection is a copper connector with a large diameter portion and a small neck, and the large diameter portion of the copper connector is welded to one end opening of the straight pipe portion.

[0008] As a further optimization of the above technical solution, the stainless steel plate or copper plate is welded to the inner wall of the other end of the straight pipe.

[0009] As a further optimization of the above technical solution, the stainless steel plate or copper plate is welded to the end face of the other end of the straight pipe section.

[0010] As a further optimization of the above technical solution, the stainless steel plate or copper plate is provided with an upward flange around its perimeter, and the upward flange is welded to the outer wall of the other end of the straight pipe section.

[0011] As a further optimization of the above technical solution, the outer side of the shunt copper connector is provided with an enlarged diameter section.

[0012] As a further optimization of the above technical solution, the snap-fit ​​part is formed by engraving, pressing or welding upper and lower snap-fit ​​blocks, and a snap-fit ​​groove is formed between the upper and lower snap-fit ​​blocks to snap the filter screen, and the periphery of the filter screen is snapped onto the snap-fit ​​groove.

[0013] The advantages of this invention compared to the prior art are:

[0014] 1. Most of the materials in this utility model are made of stainless steel, which not only reduces production costs, but also, due to the high strength, resistance to deformation and good corrosion resistance of stainless steel, gives the distributor the characteristics of high strength, resistance to deformation and good corrosion resistance.

[0015] 2. This utility model has a simple structure, low production and maintenance costs, long service life, and is easy to promote and apply. Attached Figure Description
