Description

Technical Field

[0001] This utility model relates to the field of liquid cooling equipment connectors, and in particular to a self-relief assembly and a fluid connector. Background Technology

[0002] When a liquid cooling device is not connected, its internal pressure increases due to factors such as ambient temperature. If the pressure is not released, the liquid cooling device will be damaged due to excessive pressure. Based on this, existing technologies often use self-relieving pressure components (such as the modular pressure relief component that can automatically relieve pressure disclosed in application number 201911131723.4) to avoid this situation. However, most existing self-relieving pressure components do not have the function of adjusting the pressure they can withstand and cannot be used for different types of liquid cooling devices in different environments at the same time.

Detailed Implementation

[0028] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0029] Example 1

[0030] like Figure 1As shown, the present invention provides a self-relieving pressure assembly, including a pressure relief part 1 and a pressure relief component 5, wherein the pressure relief part 1 is provided with a pressure relief channel 2 and a pressure relief groove 3 communicating with the pressure relief channel 2;

[0031] The pressure relief component 5 is installed in the pressure relief groove 3. The pressure relief component 5 has a second pressure relief channel 4. An elastic element for sealing the first pressure relief channel 2 is provided in the second pressure relief channel 4.

[0032] The pressure relief component 5 has the freedom to move along the length of the pressure relief groove 3, so that the pressure of the elastic element against the pressure relief channel 2 is adjustable;

[0033] In addition, a sealing ring 6 is installed in the pressure relief groove 3. The sealing ring 6 contacts the end of the pressure relief component 5. The sealing ring 6 is used to prevent liquid from entering the contact surface between the pressure relief component 5 and the pressure relief groove 3.

[0034] The elastic element in this embodiment includes a spring 7 and a sealing element 8 connected to the spring 7. The sealing element 8 can be spherical.

[0035] In some other embodiments, the inner diameter of spring 7 is larger than the inner diameter of pressure relief channel 2, and the sealing member 8 is located inside spring 7. In this case, the spring plays a role in limiting the sealing member 8. Compared with connecting the sealing member 8 to the end of spring 7, it can better prevent the sealing member 8 from deviating from the opening of pressure relief channel 2. In addition, spring 7 in this embodiment is a cylindrical helical compression spring, but a conical helical compression spring can also be used.

[0036] In this embodiment, the position adjustment method of the pressure relief component 5 is as follows: the pressure relief component 5 is threadedly connected to the pressure relief groove 3;

[0037] By adjusting the position of the pressure relief component 5, the pressure applied by the elastic element to the inlet of the pressure relief channel 2 can be adjusted, thereby realizing the function of adjusting the pressure that the self-pressure relief component can withstand.

[0038] When the internal pressure of the liquid cooling equipment exceeds the pressure value that the self-relieving pressure assembly can withstand, spring 7 is compressed, and the sealing part 8 separates from the opening of the pressure relief channel 2 under water pressure. The liquid inside the liquid cooling equipment then flows out of the self-relieving pressure assembly through the pressure relief channel 2, the pressure relief groove 3, and the pressure relief channel 4 in sequence, completing the self-relieving pressure and effectively preventing the liquid cooling equipment from being damaged due to excessive pressure.

[0039] Example 2

[0040] like Figures 1-3 As shown, this embodiment proposes a fluid connector, including the self-relief assembly of Embodiment 1, and also including a housing 9, a flange seat 10, and a loose sleeve 11;

[0041] The pressure relief part 1 is a valve stem, the pressure relief channel 2 is connected to the internal space of the housing 9, and the valve stem is limited to the housing 9 by a snap ring 12; a spring 13 is connected between the sleeve 11 and the valve stem.

[0042] To achieve a sealing effect, the valve stem is connected to the sleeve 11 by a second sealing ring 14, the sleeve 11 is connected to the housing 9 by a third sealing ring 15, and the housing 9 is connected to the flange seat 10 by a fourth sealing ring 16. A fifth sealing ring 17 is provided on the side of the flange seat 10, and a sealing groove for limiting the movement is opened on the side of the flange seat 10, which realizes the limiting of the inner and outer diameters of the fifth sealing ring 17, improving the sealing stability and service life of the fifth sealing ring 17.

[0043] In this embodiment, the pressure relief channel 2 includes a pipe 18 distributed along the axial direction of the valve body and at least one pipe 2 (not shown in the figure) distributed along the radial direction of the valve body. The pipe 2 is connected to the pipe 18. The pipe 2 is not necessarily distributed along the radial direction of the valve body, but can be in other directions.

[0044] In addition, the length of pipe 18 in this embodiment is at least twice the length of pipe 2. Increasing the length of pipe 18 increases the upper limit of the pressure that the self-relieving pressure assembly can withstand.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
