Description

Technical Field

[0001] The utility model relates to the technical field of three-way joints, and particularly relates to an integrated three-way joint convenient for installation. Background Technique

[0002] The air-conditioning three-way joint is a key component in the air-conditioning system. It is used to connect three pipelines, usually for the distribution and management of refrigerants. After the refrigerant flows out of the compressor, it can enter the condenser through one branch, and then enter two evaporators respectively through the other two branches, or vice versa. The refrigerant from the two evaporators is merged and then returned to the compressor, allowing the air-conditioning system to distribute the refrigerant more effectively and improve the operating efficiency of the system. During assembly, the air-conditioning three-way joint and the air-conditioning pipe are installed in the narrow space of the air-conditioning housing, and it is necessary to bend the air-conditioning pipe or other methods to ensure installation, which is likely to cause the air-conditioning pipe to break or deform, seriously affecting the sealing performance of the pipeline connection;

[0003] Chinese Patent Publication No. CN218883311U discloses a three-way pipe joint, which includes a rigid three-way female pipe, a straight sub-pipe, a flexible pipe, an outer support pipe, and a pipe clamp. Flange plates for connection are symmetrically fixed at both ends of the rigid three-way female pipe. Both ends of the flexible pipe are communicated with the other port of the rigid three-way female pipe and one end of the straight sub-pipe respectively. A flange plate is also fixed at the other end of the straight sub-pipe. Embedding grooves for the pipe clamp to be inserted are fixed on the rigid three-way female pipe and the straight sub-pipe. The pipe clamp is in a semi-circular arc shape and ear plates are fixed at both ends thereof. After fixing the line of the rigid three-way female pipe, the flexible pipe is wound around the side pipe that is on the side of the rigid three-way female pipe and blocks the side opening pipe of the rigid three-way female pipe. The flexible action of the flexible pipe avoids the traditional process of using two right-angle pipe joints for bypassing. In contrast, the operation is simpler, there are fewer leakage hidden points at the connection, and there are fewer hidden points. In the above technology, the flexible action of the flexible pipe can facilitate the installation of the three-way joint, but the corrosion resistance of the flexible pipe is poor and it is difficult to use for a long time. Moreover, the inner wall of the flexible pipe is covered with wrinkles, which is likely to cause the three-way joint to accumulate dirt, and even cause a serious risk of blockage. Therefore, the utility model discloses an integrated three-way joint convenient for installation to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an integrated three-way joint convenient for installation, and solve the technical problems that the traditional three-way joint can be conveniently installed through the flexible action of the flexible pipe, but the corrosion resistance of the flexible pipe is poor and it is difficult to use for a long time. Moreover, the inner wall of the flexible pipe is covered with wrinkles, which is likely to cause the three-way joint to accumulate dirt, and even cause a serious risk of blockage.

Specific embodiments

[0020] The following is only the preferred embodiment of the utility model, and the protection scope is not limited to this embodiment. All technical solutions falling within the idea of the utility model shall belong to the protection scope of the utility model. At the same time, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements should also be regarded as the protection scope of the utility model.

[0021] See Figures 1 to 5 As shown, an integrated three-way joint that is convenient for installation includes a three-way pipe body 1. A first sealing ring 2 is installed on the inner wall of one end of the three-way pipe body 1, and a first concave ring 11 is provided on the inner wall of the end of the three-way pipe body 1 corresponding to the first sealing ring 2;

[0022] Specifically, the first concave ring 11 provides a clear installation position for the first sealing ring 2, ensuring that the sealing ring can be correctly installed at the predetermined position. When inserting the air-conditioning pipe, the first sealing ring 2 is squeezed between the first concave ring 11 and the air-conditioning pipe, thereby ensuring its sealing effect.

[0023] Furthermore, expansion joints 3 are installed at the other two ends of the three-way pipe body 1. The two expansion joints 3 are not on the same straight line. An external thread 33 is provided on the outer wall of the expansion joint 3, and a corresponding internal thread 12 is provided on the inner wall of the end of the three-way pipe body 1 corresponding to the external thread 33, so that the external thread 33 can rotate a certain length along the internal thread 12;

[0024] Specifically, the installation steps are as follows: Align the end of the tee pipe body 1 with the air-conditioning pipe, rotate the expansion joint 3, and the external thread 33 is threadedly engaged with the internal thread 12, so that the expansion joint 3 spirally extends out of the tee pipe body 1. Until the expansion joint 3 is press-fitted with the air-conditioning pipe, the clamp 5 is snapped onto the outside of the expansion joint 3, which can limit the positions of the expansion joint 3 and the air-conditioning pipe, prevent loosening at the interface between the expansion joint 3 and the air-conditioning pipe, and the clamp 5 is used to prevent the retaining ring 31 from moving in the reverse direction, so that the expansion joint 3 is pressed against the air-conditioning pipe.

[0025] Further, sealing rings II 4 are installed on the inner walls of the expansion joints 3, and third concave rings 32 are provided on the inner walls of the retaining rings 31 corresponding to the sealing rings II 4;

[0026] Specifically, the third concave rings 32 provide an accurate installation position for the sealing rings II 4, ensuring that the sealing rings can be correctly placed and fixed on the inner walls of the retaining rings 31. When the air-conditioning pipe is inserted, the sealing rings II 4 are squeezed between the third concave rings 32 and the air-conditioning pipe, which can ensure the joint seal. It is worth noting that a gradually widening connecting portion is provided on the outer side of the end of the air-conditioning pipe. After being inserted into the retaining ring 31, the gradually widening connecting portion is press-fitted with the retaining ring 31, playing a role in preventing loosening and strengthening the seal.

[0027] Further, clamps 5 are sleeved on the outer sides of the expansion joints 3. The clamps 5 are made of stainless steel material, and the clamps 5 are in a "C" - shaped structure;

[0028] Specifically, the stainless steel material has good corrosion resistance and strength, enabling the clamps 5 to maintain stable performance in various environments and extending the service life. The "C" - shaped structure of the clamps 5 can be conveniently installed on the expansion joints 3 and prevent falling off after installation.

[0029] Further, retaining rings 31 are fixed at the ends of the expansion joints 3, and the clamps 5 are located between the retaining rings 31 and the ends of the tee pipe body 1;

[0030] Specifically, the main function of the clamps 5 is to fix the expansion joints 3 and prevent them from loosening due to vibration or pressure changes during operation. The clamps 5 are located between the retaining rings 31 and the tee pipe body 1. This position makes the clamps 5 more accessible and operable by the operator, facilitating installation and maintenance.

[0031] Further, the expansion joints 3 and the tee pipe body 1 are hermetically connected through sealing rings III 6, and second concave rings 13 are provided on the inner walls of the tee pipe body 1 corresponding to the sealing rings III 6;

[0032] Specifically, a concave ring structure is specially designed on the inner wall of the tee body 1 to accommodate and install the sealing ring III 6, which can ensure that the sealing ring III 6 is better fixed in the preset position. The sealing ring III 6 is squeezed between the inner wall of the tee body 1 and the outer wall of the expansion joint 3, and the sealing ring III 6 can always maintain the sealing performance during the spiral displacement of the expansion joint 3.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
