Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration components, and more specifically to a corrugated pipe assembly. Background Art

[0002] In the refrigeration field, copper joints are required to connect various pipes for refrigerant transportation. Currently, brass fittings and nuts are commonly used at the threaded connections of the joints. The physical properties of this material itself and its common design structure have low torsional strength. When installing machines at the customer site or performing market repairs, the joints are easily broken due to exceeding the rated torsional moment value. In addition, after high and low temperature alternation, due to the thermal expansion and contraction characteristics of the metal material, the original sealing effect cannot be achieved at the joint fit, resulting in leakage incidents.

[0003] Generally, the pipes are made of stainless steel, and it is not easy to weld with brass joints, with low efficiency and unstable welding quality, which is not conducive to automated welding. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a corrugated pipe assembly with reasonable structure, convenient welding and high strength in view of the deficiencies of the prior art.

[0005] A corrugated pipe assembly includes a corrugated pipe. One side of the corrugated pipe is provided with a first joint. The outer side of the first joint is provided with a threaded structure, and a tapered section is provided on the inner side of the first joint. The corrugated pipe abuts against the tapered section. A second joint is sleeved on the first joint, and a cylindrical protrusion is provided on the second joint, and the protrusion fits with the inner hole of the first joint. The first joint is made of red copper, and the second joint is made of stainless steel. The other side of the corrugated pipe is provided with a distributor assembly. The refrigerant enters from the first joint, is then distributed to each pipeline by the distributor assembly end, and then flows out. The structure is reasonable and the processing is convenient. The structure is strengthened by the protrusion, with high torsional strength and not easy to break. The sealing effect is good and leakage will not be caused.

[0006] That is, the high strength characteristics of stainless steel material are utilized, and the good sealing characteristics of red copper are also utilized. When connecting red copper in the utility model with the red copper of the client, the same material has the same deformation coefficient and will not cause leakage, that is, the joint leakage incident caused by high and low temperature alternation is avoided.

[0007] The joint form of red copper stacked with stainless steel utilizes the high strength of stainless steel to bear the load and the good sealing plasticity of red copper as the sealing surface, achieving the advantage of "rigid inside and flexible outside". Moreover, the welding of red copper and stainless steel reduces the number of weld points and realizes automated production.

[0008] As a further improvement and supplement to the above solution, the utility model further includes the following additional technical features:

[0009] The described dispenser assembly includes a housing, an impeller, and a dispenser. With a reasonable structure, the dispenser assembly rotates and distributes by the impact of refrigerant on the impeller, ensuring uniform distribution among pipelines.

[0010] One side of the described first joint has a fillet transition. It provides safety protection and will not damage other parts.

[0011] The outer side of the described second joint has a hexagonal structure. The connection and fastening are convenient and fast.

[0012] The described corrugated pipe is brazed to the first joint, the second joint, and the dispenser assembly. The welding is firm and reliable.

[0013] The described corrugated pipe is made of stainless steel. It has good flexibility and low cost.

[0014] Using the present utility model can achieve the following beneficial effects: The present utility model has a reasonable structure, is convenient to process, has high torsional strength, and is not easily broken. The sealing effect is good and will not cause leakage. When welded with a copper joint, it is easy to weld, has high efficiency, and the welding quality is stable, which is conducive to automated welding. The corrugated pipe made of stainless steel has good flexibility.

[0015] That is, it utilizes the high-strength characteristics of stainless steel and the good sealing characteristics of copper. When connecting the copper in the present utility model with the copper on the client side, the same material has the same deformation coefficient and will not cause leakage, that is, it avoids the joint leakage events caused by high and low temperature alternation.

[0016] The joint form of copper stacked on stainless steel utilizes both the high strength of stainless steel to bear the load and the good sealing plasticity of copper as the sealing surface, achieving the advantage of "rigid inside and flexible outside". Moreover, the welding of copper and stainless steel reduces the number of weld points and realizes automated production. Description of the Drawings

[0022] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0023] As shown Figures 1-5 in the figure, the utility model relates to a corrugated pipe assembly.

[0024] The corrugated pipe assembly described in this embodiment includes a corrugated pipe 3. On one side of the corrugated pipe 3, there is a first joint 1. The outer side of the first joint 1 is provided with a threaded structure. On the inner side of the first joint 1, there is a tapered section 11. The corrugated pipe 3 abuts against the tapered section 11. A second joint 2 is sleeved on the first joint 1. The second joint 2 is provided with a cylindrical protrusion 21. The protrusion 21 fits and is welded to the inner hole of the first joint 1 to strengthen the structure. The first joint 1 is made of copper, and the second joint 2 is made of stainless steel. The corrugated pipe 3 is welded to the first joint 1 and the second joint 2. On the other side of the corrugated pipe 3, there is a distributor assembly 4. The refrigerant enters from the first joint 1, is then distributed by the distributor assembly 4, and then flows out.

[0025] Furthermore, the distributor assembly 4 includes a housing 41, an impeller 42, and a distributor 43. The housing 41 is provided with the impeller 42 inside, and the distributor 43 with multiple holes is arranged outside the impeller 42.

[0026] Furthermore, one side of the first joint 1 has a fillet 12 transition.

[0027] Furthermore, the outer side of the second joint 2 has a hexagonal 22 structure.

[0028] Furthermore, the corrugated pipe 3 is connected to the first joint 1, the second joint 2, and the distributor assembly 4 by brazing. The corrugated pipe 3 is welded to the housing 41 in the distributor assembly 4.

[0029] Even further, the corrugated pipe 3 is made of stainless steel.

[0030] When this corrugated pipe assembly is in use, the refrigerant enters from the first joint 1 end, passes through the corrugated pipe 3, then enters the housing 41. The refrigerant on the housing 41 impacts on the impeller 42 to rotate and distribute, and then is output to each pipeline on the distributor 43 for refrigerant distribution and output.

[0031] The above is the preferred implementation mode of the utility model, which does not limit the protection scope of the utility model. Any deformation and improvement made by those skilled in the art according to the design idea of the utility model should be regarded as within the protection scope of the utility model.
