Description

Technical Field

[0001] This utility model belongs to the field of air conditioning accessories technology, specifically a novel aluminum throttling device assembly with an embedded throttling ring structure. Background Technology

[0002] Currently, the process of embedding throttling rings in air conditioning and refrigeration pipe fittings and limiting their movement mostly adopts a local spinning process. By spinning the throttling ring to compress it from the front and back, the purpose of preventing its movement is achieved. However, this process is limited to copper pipe fittings. Copper pipe fittings have good local limiting properties when using this process, but it is obviously not feasible to use aluminum pipes. Because aluminum is relatively soft, high-pressure spinning will damage the aluminum pipe. In the context of high copper prices and the trend of aluminum replacing copper, it is urgent to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a novel aluminum throttle assembly with an embedded throttle ring structure to solve the problems mentioned in the background art.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A novel aluminum throttling device assembly with an embedded throttling ring structure includes a main pipe, the main pipe having an enlarged section, and a throttling ring disposed within the enlarged section.

[0006] Preferably, the enlarged section adopts a multi-stage stepped core rod for enlargement, and after the throttling ring is placed in the enlarged section, the multi-stage stepped core rod is used for shrinking and rounding.

[0007] Preferably, the flaring length tolerance of the multi-segment stepped core rod is +0.1 / 0 mm, the inner diameter tolerance is +0.1 / 0 mm, and the narrowing and rounding tolerance is ±0.2 mm.

[0008] Preferably, the enlarged section adopts a limiting step structure, and the throttling ring is located at the end of the limiting step.

[0009] Preferably, the main pipe is connected to several branch pipes on its outer side.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] In this invention, a limiting step is obtained by expanding the hole inside the aluminum tube. After inserting the throttling ring, the opening is narrowed and rounded, thereby realizing the installation of the throttling ring inside the aluminum tube. This effectively solves the problem of embedding the throttling ring inside a smooth aluminum tube. Compared with the spinning and pressing method used for copper tubes, this solution is simpler, more suitable for the soft characteristics of aluminum tubes, makes up for the shortcomings, solves the defects in aluminum tube processing, and has strong practicality.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example:

[0027] A novel aluminum throttle assembly with an embedded throttle ring structure, such as Figure 1-2 As shown, it includes a main pipe 1, which has an enlarged section 11 and a throttling ring 2 inside the enlarged section 11.

[0028] In one possible implementation, the enlarged section 11 is enlarged by a multi-stage stepped core rod. After the throttling ring 2 is placed inside the enlarged section 11, the multi-stage stepped core rod is used for shrinking and rounding.

[0029] In one possible implementation, the flared length tolerance of the multi-segment stepped core rod is +0.1 / 0 mm, the inner diameter tolerance is +0.1 / 0 mm, and the narrowing and rounding tolerance is ±0.2 mm.

[0030] In one possible implementation, the enlarged section 11 adopts a limiting step structure, and the throttling ring 2 is located at the end of the limiting step.

[0031] In one possible implementation, the main pipe 1 is connected to several branch pipes 3 on its outer side.

[0032] In one possible implementation, the embedded end of the main pipe 1 is first flared using a stepped long core rod to form a limiting step. Then, a throttling ring 2 with an inner diameter equivalent to the flared section 11 of the main pipe 1 is inserted to ensure that the throttling ring 2 is fully pressed against the bottom of the flared end of the aluminum tube 1 and flattened. Then, a flaring and rounding mold designed according to the drawing dimensions is used to flare and round the tube, thereby limiting the throttling ring 2. The throttling ring 2 is checked to see if it is loose and if its dimensions meet the requirements, thus achieving the purpose of embedding without loosening.

[0033] In one possible implementation, the novel aluminum tube embedded with a throttling ring structure is mainly used in the air conditioning and refrigeration industry (household air conditioners). It effectively solves the problem of embedding a throttling ring in a smooth aluminum tube. Compared with the spinning and pressing method used for copper tubes, this solution is simpler, more suitable for the soft characteristics of aluminum tubes, makes up for the shortcomings, solves the defects in aluminum tube processing, and is highly practical.

[0034] Working principle, refer to Figure 1-2 :

[0035] Step 1: Determine the embedding requirements, including depth, size, and inner diameter;

[0036] Step 2: Make the corresponding multi-step long flaring, long shrinking, and rounding molds according to the requirements. The tolerances should be similar to the tolerances shown in the two-dimensional engineering drawing below to ensure that the tightness is appropriate, the insertion is smooth, and the aluminum tube or throttling ring will not be damaged during shrinking and rounding.

[0037] Step 3: Perform a multi-step long flare on one end of the aluminum tube;

[0038] Step 4: Insert the throttle ring, ensuring it reaches the bottom of the flare, and flatten it;

[0039] Step 5: Narrow the opening and round it to ensure that the throttling ring is compacted and tight.

[0040] Step 6: Check if the dimensions meet the requirements of the drawing.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
