Description

Technical Field

[0001] This utility model belongs to the field of liquid-cooled quick-change connection technology, specifically relating to a low-resistance rotatable ball valve connection structure. Background Technology

[0002] In the field of liquid cooling quick-connection, centralized cooling devices (such as data center server cooling systems, industrial equipment cooling systems, etc.) typically need to connect hundreds or even thousands of liquid cooling hoses, and the length of a single hose can reach ten meters.

[0003] Traditional ball valves and hose fittings are completely fixed after connection and cannot rotate relative to each other. During installation, if the hose becomes twisted, the operator cannot adjust it by rotating the hose because the fitting and ball valve cannot rotate. The only solution is to disassemble the entire fitting (e.g., unscrew the threaded connector, remove the retaining clips, and pull out the locating pins), then reassemble the hose, wasting a lot of time. This not only seriously affects the operation and maintenance efficiency of the cooling system but may also lead to equipment overheating due to prolonged downtime, increasing the risk of data loss or equipment damage.

[0004] Therefore, in order to solve the above problems, it is necessary to design a low-resistance, rotatable ball valve connection structure. Utility Model Content

[0005] The purpose of this invention is to provide a low-resistance, rotatable ball valve connection structure to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a low-resistance rotatable ball valve connection structure, comprising: The valve body has an annular recess on the inner wall of one end; The hose connector has several ball bearing placement sections on the outer wall of one end; among them When one end of the hose connector is inserted into one end of the valve body, the ball placement parts are aligned with the annular recess. Several balls are arranged in the annular recess and the corresponding ball placement part to limit the axial movement of the valve body and hose connector.

[0007] Furthermore, the outer wall of the valve body is provided with a threaded hole; wherein The threaded hole communicates with the annular recess; and Each of the aforementioned balls is adapted to pass through the threaded hole and then enter the corresponding ball placement part.

[0008] Furthermore, a countersunk screw without a cap is provided in the threaded hole; wherein The capless countersunk screw is threaded into the threaded hole, and the threaded connection is provided with sealant.

[0009] Furthermore, the hose connector is provided with an abutment surface; wherein The contact surface is adapted to contact the end face of the valve body; and When the contact surface comes into contact with the end face of the valve body, each ball placement part aligns with the annular recess.

[0010] Furthermore, each of the aforementioned ball bearing placement portions is arranged in a circular array on the outer wall of the hose connector; wherein The ball bearing placement section is cylindrical and accommodates 2 / 5 to 3 / 5 of the ball bearing height; and The annular recess is adapted to accommodate the remaining portion of the ball height, so that the ball is completely located within the annular recess and the ball placement portion.

[0011] Furthermore, at least one sealing ring placement portion is provided on the outer wall of one end of the hose connector; wherein The sealing ring placement portion is suitable for placing a sealing ring; and When the sealing ring placement part is located inside the valve body, the sealing ring is in contact with the inner wall of the valve body.

[0012] The beneficial effects of this utility model are: (I) When it is necessary to connect the hose connector to the valve body, one end of the hose connector is inserted into one end of the valve body. At this time, each ball placement part is aligned with the annular recess. The balls are placed in the annular recess and the corresponding ball placement part. The balls limit the axial movement of both. During the operation of the liquid cooling system, when the hose is twisted or other issues require adjustment, the operator can easily rotate the hose connector or valve body due to the rolling action of the balls, so that they rotate relative to each other, thereby adjusting the state of the hose and eliminating the twist.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0019] like Figures 1 to 3 As shown, this embodiment provides a light-resistance rotatable ball valve connection structure, including: The valve body 1 has an annular recess 101 on its inner wall at one end; the hose connector 2 has a plurality of ball bearing placement portions 201 on its outer wall at one end; when one end of the hose connector 2 is inserted into one end of the valve body 1, each ball bearing placement portion 201 is aligned with the annular recess 101; a plurality of balls 3 are disposed in the annular recess 101 and the corresponding ball bearing placement portions 201 to axially limit the valve body 1 and the hose connector 2; the axial limiting of the valve body 1 and the hose connector 2 by the balls 3 can effectively prevent the two from separating in the axial direction, ensuring the stability of the connection structure. Even when the cooling system is affected by liquid pressure and vibration during operation, it can ensure that the valve body 1 and the hose connector 2 are tightly connected and will not loosen or fall off, reducing the risk of liquid leakage; the rolling characteristics of the balls 3 greatly reduce the relative rotational resistance between the valve body 1 and the hose connector 2, and when the operator adjusts the hose state, only a small force is needed to easily rotate the hose connector 2 or the valve body 1, improving the convenience and flexibility of operation.

[0020] In this embodiment, when it is necessary to connect the hose connector 2 to the valve body 1, one end of the hose connector 2 is inserted into one end of the valve body 1. At this time, each ball placement part 201 is aligned with the annular recess 101, and the ball 3 is placed in the annular recess 101 and the corresponding ball placement part 201. The ball 3 limits the axial movement of both. During the operation of the liquid cooling system, when the hose is twisted or other issues require adjustment, the operator can easily rotate the hose connector 2 or the valve body 1 due to the rolling action of the ball 3, causing them to rotate relative to each other, thereby adjusting the state of the hose and eliminating the twist.

[0021] The outer wall of the valve body 1 is provided with a threaded hole 102; wherein the threaded hole 102 communicates with the annular recess 101; and each of the balls 3 is adapted to pass through the threaded hole 102 and enter the corresponding ball placement part 201; wherein by setting the threaded hole 102 to communicate with the annular recess 101, the balls 3 can pass through the threaded hole 102 and enter the corresponding ball placement part 201, so as to facilitate the installation and replacement of the balls 3; wherein since the outer wall of the hose connector 2 is located inside the valve body 1, only when the ball placement part 201 is aligned with the threaded hole 102 can the balls 3 be simultaneously located in the annular recess 101 and the ball placement part 201. At this time, the hose connector 2 is rotated to align the next ball placement part 201 with the threaded hole 102, until all ball placement parts 201 contain balls 3.

[0022] A capless countersunk screw 4 is provided in the threaded hole 102; the capless countersunk screw 4 is threadedly connected to the threaded hole 102, and a sealant is provided at the threaded connection; by providing the capless countersunk screw 4, the capless countersunk screw 4 can be completely located inside the valve body 1, while preventing the ball 3 from falling off and preventing liquid from flowing out of the threaded hole 102; by providing a sealant at the threaded connection between the capless countersunk screw 4 and the threaded hole 102, the sealing effect is further enhanced, ensuring that liquid will not leak through the tiny gap at the threaded connection, thereby improving the sealing performance of the entire connection structure.

[0023] The hose connector 2 is provided with an abutment surface 202; wherein the abutment surface 202 is adapted to contact the end face of the valve body 1; and when the abutment surface 202 contacts the end face of the valve body 1, each ball placement part 201 is aligned with the annular recess 101; wherein by providing the abutment surface 202, a quick positioning effect is achieved when the valve body 1 is connected to the hose connector 2, so as to ensure that each ball placement part 201 is aligned with the annular recess 101, so that the ball 3 can be accurately installed in the designated position.

[0024] Each of the aforementioned ball bearing placement portions 201 is arranged in a circular array on the outer wall of the hose connector 2; wherein the ball bearing placement portion 201 is cylindrical and accommodates 2 / 5 to 3 / 5 of the height of the ball bearing 3; and the annular recess 101 is adapted to accommodate the remaining portion of the height of the ball bearing 3, so that the ball bearing 3 is completely located within the annular recess 101 and the ball bearing placement portion 201; wherein eight balls bearing 3 are preferably used; wherein the circular array arrangement of the ball bearing placement portions 201 on the outer wall of the hose connector 2 ensures that the ball bearing 3 is evenly distributed on the outer wall of the hose connector 2, thereby providing a uniform axial limiting force for the hose connector 2, avoiding loosening or displacement of the connection due to uneven force, and greatly improving the connection performance. To ensure connection stability, the hose connector 2 and valve body 1 are tightly connected under all working conditions, preventing liquid leakage. The ball bearing placement part 201 is cylindrical and accommodates 2 / 5 to 3 / 5 of the height of the ball bearing 3. Together with the annular recess 101, it provides suitable space for the ball bearing 3 to move, ensuring axial positioning. It is optimal for the ball bearing placement part 201 to accommodate 2 / 5 or 3 / 5 of the height of the ball bearing 3 to reduce the resistance between the ball bearing 3 and the valve body 1 and hose connector 2. This ensures more flexible relative rotation between the valve body 1 and hose connector 2, allowing operators to adjust the hose with only a small force, reducing operational difficulty and labor intensity.

[0025] At least one sealing ring placement portion 203 is provided on the outer wall of one end of the hose connector 2; wherein the sealing ring placement portion 203 is adapted to place a sealing ring; and when the sealing ring placement portion 203 is located inside the valve body 1, the sealing ring is in contact with the inner wall of the valve body 1; wherein by providing the sealing ring placement portion 203, a stable installation position is provided for the sealing ring; when the hose connector 2 is inserted into the valve body 1, the sealing ring placement portion 203 is located inside the valve body 1, and at this time the sealing ring placed in the sealing ring placement portion 203 is in close contact with the inner wall of the valve body 1, further enhancing the sealing performance of the connection part and preventing liquid leakage.
