The liquid cooling loop is connected to the server rack via valve connectors to ensure continuity and achieve cyclical heat exchange. However, in existing technologies, the valve connectors are prone to leakage during rotation, leading to liquid spillage. Summary of the Invention

[0003] The purpose of this invention is to provide a quick valve connector that facilitates the opening and closing of fluid channels, ensures convenient and stable pipe connections, and avoids loosening of the connection between the connector and the tubular body due to rotation during the connection process between the connector and the external pipe.

The pipe connector, with one end embedded in the tubular body, is connected to the tubular body by a flexible rib embedded in the annular groove and the groove, respectively.

[0006] The following are further improvements to the above technical solution:

[0008] 2. In the above scheme, the flexible rib is made of iron wire, steel wire or copper wire.

[0009] 3. In the above scheme, the strip grooves extending circumferentially are distributed on at least three-quarters of the circumference.

[0010] 4. In the above scheme, the outer wall of the pipe joint and the inner wall of the tubular body are sealed together by at least two joint sealing rings that are spaced apart along the axial direction.

[0011] 5. In the above scheme, at least two of the joint sealing rings are located axially between the ball and the flexible rib.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] This utility model relates to a quick-connect valve. A circumferentially extending strip-shaped through-hole is formed on the outer wall of the tubular body near the pipe connector end.

An annular groove, corresponding to the strip-shaped groove, is formed on the outer wall of the pipe connector. The pipe connector, with one end embedded in the tubular body, is connected to the tubular body via flexible ribs embedded in the annular groove and the strip-shaped groove, respectively. This design allows for quick opening and closing of the fluid channel, facilitates connection between the tubular body and external pipelines via the pipe connector, and ensures the convenience and stability of the connection between the pipe connector and the tubular body.

[0023] As a component connecting to external pipelines, the pipe connector is mounted on a tubular body at one end. When it is necessary to connect the pipe connector to the tubular body, one end of the pipe connector is first inserted into the tubular body, so that the annular groove on the pipe connector and the strip groove on the tubular body are at the same height. Then, one end of a flexible rib, such as an iron wire, is inserted through the strip through hole on the tubular body between the annular groove and the strip groove, and the iron wire moves circumferentially in the area between the annular groove and the strip groove until it exits through the strip through hole on the tubular body, thereby achieving the connection between the pipe connector and the tubular body.

[0028] The aforementioned pipe joint 8 has a thread on the side wall opposite to one end of the tubular body 1 for connecting to an external pipe.

[0029] Example 2: A quick valve connector includes: a tubular body 1 and a pipe connector 8 installed at one end of the tubular body 1. A ball 2 is rotatably disposed inside the other end of the tubular body 1. A flow channel through hole 3 is formed on the ball 2 with one diameter as its axis of rotation, which is perpendicular to its axis of rotation. When the ball 2 rotates to the 0° position, the direction of the flow channel through hole 3 is perpendicular to the axis of the tubular body 1, and the outer circumferential surface of the ball 2 is sealed to the inner wall of the tubular body 1. When the ball 2 rotates to the 90° position, the direction of the flow channel through hole 3 is parallel to the axis of the tubular body 1, and the internal flow channels of the tubular body 1 located on both sides of the ball 2 are connected through the flow channel through hole 3 on the ball 2.

[0030] A strip-shaped through hole 11 extending in a circumferential direction is provided on the outer side wall of the tubular body 1 near the pipe connector 8. A strip-shaped groove 12 extending in a circumferential direction is provided on the inner side wall of the tubular body 1.

An annular groove 13 extending in the full circumferential direction and corresponding to the strip-shaped groove 12 is provided on the outer side wall of the pipe connector 8. The pipe connector 8, with one end embedded in the tubular body 1, is connected to the tubular body 1 by a flexible rib 14 embedded in the annular groove 13 and the strip-shaped groove 12 respectively.

[0031] When the pipe fitting is connected to the external pipe by rotation during subsequent use, the pipe fitting and the tubular body can still maintain a stable connection even when they rotate relative to each other.

[0032] The aforementioned flexible rib 14 is a metal wire; the aforementioned flexible rib 14 is a copper wire.

[0033] The outer wall of the aforementioned pipe joint 8 is sealed to the inner wall of the tubular body 1 by at least two joint sealing rings 15 spaced apart along the axial direction; the aforementioned at least two joint sealing rings 15 are located axially between the ball 2 and the flexible rib 14.

[0035] The tubular body 1 is provided with a first annular flange 61 on the inner wall opposite to the pipe connector 8, the inner diameter of which is smaller than the diameter of the ball 2. A second annular flange 62 is provided on the inner wall of the first annular flange 61, which is radially inward. The sealing ring 5 is provided between the second annular flange 62 and the ball 2.

[0036] An inner sealing ring 92 is installed on the side of the second annular flange 62 opposite to the sphere 2; an outer sealing ring 91 is fitted on the outer side of the tubular body 1 opposite to the end of the pipe joint 8.

[0037] The working principle of this utility model is as follows:

[0038] As a component for connecting to external pipelines, the pipe connector is installed on the tubular body at one end. When it is necessary to connect the pipe connector to the tubular body, first, one end of the pipe connector is inserted into the tubular body, and the annular groove on the pipe connector and the strip groove on the tubular body are at the same height. Then, one end of a flexible rib, such as an iron wire, is inserted from the strip through hole on the tubular body between the annular groove and the strip groove, and the iron wire is moved circumferentially in the area between the annular groove and the strip groove until it comes out from the strip through hole on the tubular body, thereby realizing the connection between the pipe connector and the tubular body.

[0039] When the pipe fitting is connected to the external pipe by rotation during subsequent use, the stable connection between the pipe fitting and the tubular body can still be maintained even when relative rotation occurs between them.

[0040] When using the above-mentioned quick valve connector, it can quickly open and close the fluid channel, facilitate the connection of the tubular body to the external pipeline through the pipe connector, and ensure the convenience and stability of the connection between the pipe connector and the tubular body. It avoids the situation where the connection between the pipe connector and the tubular body becomes loose due to rotation during the connection process with the external pipeline, thus improving the reliability of use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
