Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioner accessories, and specifically relates to a durable air conditioner capillary tube. Background Art

[0002] The air conditioner capillary tube is an important accessory in the air conditioner system and is used to regulate the refrigerant flow rate. It enables the refrigerant to transform between high pressure and low pressure through the narrow cross-section inside the tube, thereby achieving temperature and pressure control. The capillary tube functions similar to a flow control valve, capable of precisely controlling the refrigerant flow to ensure the efficient operation of the air conditioner system.

[0003] In the existing technology, the connection methods at both ends of the capillary tube usually adopt welding or nut docking. During use, it is impossible to adjust according to the refrigerant consumption, which easily causes unstable internal pressure of the capillary tube, and leakage or loosening may occur at the interfaces. Secondly, the capillary tube is generally exposed outside and is corroded by the natural environment for a long time. Coupled with the relatively humid external environment of the air conditioner, rusting and corrosion are likely to occur, reducing its service life. Summary of the Utility Model

[0004] The purpose of this utility model is to provide a durable air conditioner capillary tube that can adjust the refrigerant flow rate according to usage requirements and can protect the capillary tube to reduce the probability of damage and corrosion.

Threaded tubes are fixedly connected to both ends of the docking tubes. Inspection tubes are fixedly connected to the copper tube side wall near both ends. Sealing covers are assembled on the end faces of the inspection tubes. A protection component is also provided on the copper tube side wall.

[0007] Both ends of the copper tube extend into the threaded tubes. Sealing nuts are movably connected to the copper tube side wall near both ends. The sealing nuts are threadedly connected to the outer walls of the threaded tubes.

[0008] Annular grooves are formed on the end faces of both ends of the copper tube. Sealing rings are assembled in the annular grooves. The sealing rings are abutted against the end faces of the threaded tubes.

[0009] The protection component includes a protection tube sleeved on the copper tube side wall. Clamps are respectively assembled on the protection tube side wall near both ends. The clamps are all connected to the copper tube side wall.

[0012] The technical effects achieved by this utility model are as follows:

[0013] A durable air-conditioning capillary tube of this utility model, through the mutual cooperation among a copper tube, a butt joint tube, a ball valve, a protective component, etc., utilizes the ball valve to adjust and control according to the refrigerant flow rate requirements, avoiding the sudden increase and decrease of the internal pressure of the copper tube, which affects the internal flow rate and stability of the copper tube; in addition, by setting the protective component, the outside of the copper tube can be protected, reducing the probability of being corroded in the natural environment and extending its service life.

[0020] In order to make the purpose and advantages of this utility model clearer, the following specifically describes this utility model in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the specific protection scope claimed by this utility model.

[0021] As Figures 1 - 4 shown, a durable air-conditioning capillary tube includes a copper tube 1, butt joint tubes 2 are respectively assembled at both ends of the copper tube 1, ball valves 3 are assembled in both butt joint tubes 2, threaded tubes 4 are fixedly connected to both ends of the butt joint tubes 2, inspection tubes 5 are fixedly connected to the side wall of the copper tube 1 near both ends, sealing covers 6 are respectively assembled on the end faces of the inspection tubes 5, and the inspection tubes 5 and the sealing covers 6 are threadedly connected. By adopting the threaded connection method, on the one hand, it has good sealing performance, on the other hand, the structure is simple and the corrosion resistance is strong. A protective component is also arranged on the side wall of the copper tube 1.

[0022] As Figure 1 and Figure 4As shown, both ends of the copper tube 1 extend into the threaded tube 4. Sealing nuts 7 are movably connected to the side wall of the copper tube 1 near both ends, and the sealing nuts 7 are threadedly connected to the outer wall of the threaded tube 4.

[0023] Among them, rubber pads can be sleeved or threads can be opened on the side wall of the copper tube 1 near both ends according to actual assembly requirements to further increase the sealing performance between the sealing nut 7 and the copper tube 1.

[0024] Annular grooves are opened on the end faces of both ends of the copper tube 1, and sealing rings 8 are assembled in the annular grooves. The sealing rings 8 abut against the end faces of the threaded tube 4. The sealing ring 8 is a primary sealing structure, and the sealing nut 7 is a secondary sealing structure, which can ensure that refrigerant will not leak during the transportation process.

[0025] As Figure 1 and Figure 2 shown, the protection component includes a protection tube 9 sleeved on the side wall of the copper tube 1. Clamps 10 are respectively assembled on the side wall of the protection tube 9 near both ends, and the clamps 10 are both connected to the side wall of the copper tube 1; the protection tube 9 adopts a corrugated pipe structure.

[0026] Among them, the corrugated pipe structure can be folded, bent and stretched. When the capillary tube is in a coiled state, an appropriate length of the corrugated pipe structure can be cut according to the length of the capillary tube and sleeved on the capillary tube, and fixed with the clamp 10, which can effectively resist corrosion and rust, and thus extend the service life of the capillary tube.

[0027] The working principle of this utility model is as follows: When assembling the copper tube 1, first sleeve the protection tube 9 on the copper tube 1, then connect both ends of the copper tube 1 to the docking tube 2 through the sealing nuts 7, and then connect the docking tube 2 to the external pipeline through the threaded tube 4, and rotate the ball valve 3 to adjust the flow rate of the refrigerant entering the copper tube 1. After the copper tube 1 is assembled, protect the protection tube 9 along the bending trajectory of the copper tube 1, and tighten the clamp 10 so that it is closely attached to the copper tube 1 to protect both ends of the protection tube 9 and prevent the copper tube 1 from being exposed for a long time and being corroded by the natural environment.

[0028] The above is only the preferred implementation mode of this utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices and operation methods not specifically described and explained in this utility model are implemented according to the conventional means in the art without special explanation and limitation.
