Description

Technical Field

[0001] The utility model relates to the technical field of three-way joints, and more specifically, the utility model relates to a stop three-way joint for a liquid cooling pipeline. Background Art

[0002] At present, multiple three-way joints are provided on a liquid cooling pipeline for liquid diversion. However, not all pipelines are in use all the time. For example, when a circuit transformation is carried out on a certain branch, the branch needs to be removed first. After the removal, one end of the three-way joint needs to be blocked with a plug. After the branch transformation is completed, the plug is removed, and then the new branch is connected to the three-way joint. During the above operation process, the valve needs to be closed to prevent the liquid from flowing, that is, "water cut-off" construction. After the old branch is removed from the three-way joint, the liquid accumulated in the pipe (between the valve and the three-way joint) will flow out. How to deal with the large amount of accumulated liquid in the pipe is also a problem that needs to be considered. Therefore, in the prior art, there is still a problem that it is not easy to deal with the accumulated liquid in the pipe during "water cut-off" construction, resulting in inconvenient maintenance and assembly of the pipeline system. Summary of the Utility Model

[0025] The following further describes the present utility model in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0026] It should be understood that the terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0027] As Figures 1 - 3As shown in the figure, the utility model provides a stop three-way joint for a liquid cooling pipeline, which includes: a central section 1, and three interconnected joints arranged on the central section 1. At least one of the three joints is a stop joint 2. The number of stop joints 2 can be 1, 2 or 3. The specific setting number can be produced according to the on-site application situation. The stop joint 2 of the present invention can maintain the pipeline connection when connected to the female head joint 3, and automatically complete the pipeline closure after it is separated from the female head joint 3, avoiding the leakage of the liquid in the pipeline. To achieve the above technical effects, the utility model needs to be used in combination with a female head joint 3 that matches the stop joint 2. When the stop joint 2 is connected to the female head joint 3 provided with a female head valve stem 31, the female head valve stem 31 will open the stop joint 2 to connect the pipeline. As the female head joint 3 is disassembled, the female head valve stem 31 will also be separated from the stop joint 2, so that the pipeline changes to a closed state.

[0028] The working principle and beneficial effects of the above technical solution: By setting the stop joint 2, the pipeline can be kept closed when the joint is not in use, avoiding the outflow of liquid. When the joint needs to be used, only by connecting the stop joint 2 to the female head joint 3, the pipeline can be connected. In addition, when separated from the female head joint 3, the liquid is automatically cut off. The connection and separation of the pipeline do not require closing the valve, and there will be no situation where the remaining liquid in the pipeline flows out during the pipeline connection, making the maintenance and assembly of the pipeline system equipped with the utility model more convenient.

[0029] The stop joint 2 is composed of a tubular main body 4, a clamping member 5 arranged on the outer wall of the main body 4, a reset member 6 and a sealing member 7 arranged in the main body 4. The sealing member 7 is used to block the main body 4. The reset member 6 makes the stop joint 2 keep the sealing member 7 in the position of sealing the main body 4 when it is not connected to the female head joint 3. One end of the reset member 6 abuts against the central section 1, and the other end is connected to the sealing member 7. The sealing member 7 is movably connected to the inner wall of the main body 4. The female head valve stem 31 selectively abuts against the sealing member 7. The clamping member 5 is arranged in a ring shape on the outer side wall of the main body 4, and the end face of the clamping member 5 away from the central section 1 is an inclined surface, and the end face close to the central section 1 is a plane. As Figure 1 shown. The female head joint 3 is detachably connected to the stop joint 2 through the clamping member 5. As the female head joint 3 supporting the utility model, as Figure 2As shown in the figure, a spring buckle 32 is provided on the female connector 3. The spring buckle 32 is annular, and the central axis of the spring buckle 32 is parallel to the central axis of the female connector 3. The female connector 3 is detachably connected to the clamping member 5 through the cooperation between the spring buckle 32 and the clamping member 5. The spring buckle 32 can be a commercially available product. When the female connector 3 is inserted into the stop connector 2, it is necessary to first press down the spring buckle 32 to make the central axis of the spring buckle 32 coincide with the central axis of the female connector 3, and then insert the female connector 3 onto the stop connector 2, so that the spring buckle 32 is stuck on one side of the plane of the clamping member 5. After releasing the hand, the spring buckle 32 will be stuck with the clamping member 5, thereby preventing the female connector 3 from detaching from the stop connector 2 during use. The inclined surface of the clamping member 5 can facilitate the insertion of the female connector 3.

[0030] The central section 1 is tubular;

[0031] When the stop connector 2 is provided on the side wall of the central section 1, the end of the main body 4 is connected to the outer side wall of the central section 1 and is communicated through a communication hole provided on the side wall of the central section 1; the aperture of the communication hole is smaller than the inner diameter of the main body 4, as Figure 1 shown, so that the central section 1 can serve as a platform for the reset member 6 to abut against;

[0032] When the stop connector 2 is provided at the end of the central section 1, the end of the main body 4 is connected to the end of the central section 1, and the inner diameter of the main body 4 is larger than the inner diameter of the connection between the main body 4 and the central section 1, so that the reset member 6 can abut against the end of the central section 1.

[0033] A snap ring 8 is provided on the inner wall of the main body 4. The snap ring 8 is located at one end of the main body 4 away from the central section 1, and the inner diameter of the snap ring 8 is smaller than the inner diameter of the main body 4;

[0034] The seal 7 selectively abuts against the snap ring 8. The seal 7 is composed of a sealing portion 71 and a clamping portion 72. Both the sealing portion 71 and the clamping portion 72 are cylindrical. The diameter of the sealing portion 71 is adapted to the inner diameter of the snap ring 8, the outer diameter of the clamping portion 72 is adapted to the inner diameter of the main body 4, and one end of the clamping portion 72 is connected to the reset member 6 and the other end selectively abuts against the snap ring 8.

[0035] When the female connector 3 is not connected to the stop connector 2, under the action of the reset member 6, the sealing portion 71 is inserted into the snap ring 8, and the clamping portion 72 abuts against the snap ring 8 for positioning, thereby sealing the main body 4 and preventing liquid from flowing out, and further achieving the liquid cut-off effect.

[0036] When the female connector 3 is connected to the stop connector 2, the female valve stem 31 abuts against the sealing portion 71 and pushes the sealing portion 71 to compress the restoring member 6. The sealing portion 71 moves away from the snap ring 8, thereby forming a passage for liquid to flow through. After the spring buckle 32 is engaged with the engaging member 5, under the action of the female valve stem 31, the stop connector 2 maintains an open state. To further enhance the sealing effect of the sealing portion 71, an annular groove is provided on the outer wall of the sealing portion 71 in the circumferential direction, and a sealing ring 9 is provided in the annular groove. The sealing ring 9 can be a commercially available rubber sealing ring.
