Description

Technical Field

[0001] This utility model relates to a fluid switching valve, belonging to the field of liquid cooling technology. Background Technology

[0002] Currently, air-cooled energy storage systems account for a large proportion of the energy storage market. However, as the scale and energy density of energy storage systems increase, higher requirements will be placed on the temperature management of these systems, leading to increasing attention on liquid cooling technology. With the continuous maturation of its technology and application scenarios, the comprehensive advantages of liquid cooling—increasing energy density, reducing footprint, and lowering energy consumption—will become more prominent. However, liquid-cooled energy storage systems require additional liquid chillers and related piping systems. A well-designed piping system can save on after-sales maintenance time and improve the system's temperature uniformity.

[0003] The liquid cooling circuit is connected to the cabinet via a switching valve to ensure continuity between the circuits and enable cyclical heat exchange. However, existing switching valves are prone to instability in their closed state during connection, leading to liquid overflow. Summary of the Invention

[0004] The purpose of this invention is to provide a fluid switching valve that, while enabling rapid opening and closing of the fluid channel, facilitates the disassembly and installation of the ball and reduces the gap between the ball and the inner wall of the tubular body, thereby improving the sealing performance when the fluid channel is closed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fluid switching valve, comprising: a tubular body and a pipe connector installed at one end of the tubular body, wherein a sphere is rotatably disposed inside the other end of the tubular body, and a flow channel through hole is formed on the sphere with one diameter as its axis of rotation in a direction perpendicular to its axis of rotation. When the sphere rotates to the 0° position, the direction of the flow channel through hole is perpendicular to the axial direction of the tubular body and the outer circumferential surface of the sphere is sealed to the inner wall of the tubular body. When the sphere rotates to the 90° position, the direction of the flow channel through hole is parallel to the axial direction of the tubular body and the internal flow channels of the tubular body located on both sides of the sphere are connected through the flow channel through hole on the sphere.

[0006] A rotating handle located on the outside of a tubular body has a protrusion at one end extending radially into the tubular body. A connecting groove corresponding to the protrusion is formed on one side surface of the sphere. The protrusion is embedded in the connecting groove on the sphere and connected to the sphere by a bolt. A first positioning groove is formed on the other side surface of the sphere. One end of a positioning pin extending radially into the tubular body is rotatably embedded in the first positioning groove. The other end of the positioning pin is embedded in a second positioning groove formed on the inner wall of the tubular body and is pressed and connected to an elastic element located in the second positioning groove.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, a limiting groove is provided on the end face of one end of the positioning pin embedded in the second positioning groove for one end of the elastic member to be embedded.

[0009] 2. In the above scheme, the connecting groove, the first positioning groove, and the second positioning groove are all located on the rotation axis of the sphere.

[0010] 3. In the above scheme, the inner or outer wall of the pipe joint is provided with threads for connecting to external pipes.

[0011] 4. In the above scheme, the end face of the pipe joint facing the sphere, which is embedded in the tubular body at one end and sealed to the inner wall of the tubular body, is set as an arc-shaped inclined surface that cooperates with the sphere.

[0012] 5. In the above scheme, a sealing ring is provided between the inner wall of the tubular body opposite to the pipe joint end and the outer circumferential surface of the sphere.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This utility model relates to a fluid switching valve. One end of a rotating handle located on the outside of a tubular body has a protrusion extending radially into the tubular body. A connecting groove corresponding to the protrusion is formed on one side of a sphere. The protrusion is embedded in the protrusion on the sphere and connected to the sphere by a bolt. A first positioning groove is formed on the other side of the sphere. One end of a positioning pin extending radially into the tubular body is rotatably embedded in the first positioning groove, and the other end of the positioning pin is embedded in a second positioning groove formed on the inner wall of the tubular body and pressed together with an elastic element located in the second positioning groove. This design allows for rapid opening and closing of the fluid channel, facilitates the disassembly and installation of the sphere, and reduces the gap between the sphere and the inner wall of the tubular body, thereby improving the sealing performance when the fluid channel is closed.

[0020] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0021] Example 1: A fluid switching valve includes: a tubular body 1 and a pipe connector 7 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 opened 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.

[0022] A rotating handle 4 located on the outside of the tubular body 1 has a protrusion 41 extending radially into the tubular body 1 at one end. An inner connecting groove 91 corresponding to the protrusion 41 is formed on one side surface of the sphere 2. The protrusion 41 is embedded in the inner connecting groove 91 on the sphere 2 and connected to the sphere 2 by a bolt 92. A first positioning groove 101 is formed on the other side surface of the sphere 2. One end of a positioning pin 11 extending radially into the tubular body 1 is rotatably embedded in the first positioning groove 101. The other end of the positioning pin 11 is embedded in a second positioning groove 102 formed on the inner wall of the tubular body 1 and is pressed and connected to an elastic member 12 located in the second positioning groove 102.

[0023] During the assembly of the sphere and the tubular body, one end of the positioning pin is first embedded in the second positioning groove on the inner wall of the tubular body, and the elastic element in the second positioning groove is embedded in the limiting groove on the positioning pin. This allows the positioning pin to move radially into the second positioning groove along the tubular body by squeezing the elastic element until it is almost retracted into the second positioning groove on the inner wall of the tubular body.

[0024] The end face of the aforementioned positioning pin 11 embedded in the second positioning groove 102 is provided with a limiting groove 111 for one end of the elastic member 12 to be embedded; the aforementioned inner connecting groove 91, the first positioning groove 101, and the second positioning groove 102 are all located on the rotation axis of the ball 2.

[0025] The inner wall of the aforementioned pipe joint 7 is provided with threads for connecting to external pipes; the end face of the pipe joint 7 facing the sphere 2, which is embedded in the tubular body 1 at one end and sealed to the inner wall of the tubular body 1, is set as an arc-shaped inclined surface that cooperates with the sphere 2.

[0026] A sealing ring is provided between the protrusion 41 that rotates with the tubular body 1 and the tubular body 1.

[0027] Example 2: A fluid switching valve includes: a tubular body 1 and a pipe connector 7 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.

[0028] A rotating handle 4 located on the outside of the tubular body 1 has a protrusion 41 extending radially into the tubular body 1 at one end. An inner connecting groove 91 corresponding to the protrusion 41 is formed on one side surface of the sphere 2. The protrusion 41 is embedded in the inner connecting groove 91 on the sphere 2 and connected to the sphere 2 by a bolt 92. A first positioning groove 101 is formed on the other side surface of the sphere 2. One end of a positioning pin 11 extending radially into the tubular body 1 is rotatably embedded in the first positioning groove 101. The other end of the positioning pin 11 is embedded in a second positioning groove 102 formed on the inner wall of the tubular body 1 and is pressed and connected to an elastic member 12 located in the second positioning groove 102.

[0029] A sphere with an outer diameter slightly smaller than the inner diameter of the tubular body is inserted into the tubular body by clamping or other means, so that the first positioning groove on the sphere is aligned with the limiting groove in the second positioning groove. Under the action of the elastic element, the positioning pin moves out of the second positioning groove and embeds into the first positioning groove on the sphere.

[0030] Finally, the rotating handle with the protrusion is locked to the other side of the ball with the connecting groove by bolts, so that the rotating handle can drive the ball to rotate.

[0031] A sealing ring 5 is provided between the inner wall of the tubular body 1 opposite to the pipe connector 7 and the outer circumferential surface of the sphere 2; an outer sealing ring 81 is fitted on the outer side of the tubular body 1 opposite to the pipe connector 7.

[0032] A first annular flange 61 with an inner diameter smaller than that of the sphere 2 is provided on the inner wall of the tubular body 1 opposite to the pipe connector 7. A second annular flange 62 with a radial inward direction is provided on the inner wall of the first annular flange 61. The sealing ring 5 is disposed between the second annular flange 62 and the sphere 2. An inner sealing ring 82 is installed on the side of the second annular flange 62 opposite to the sphere 2.

[0033] The working principle of this utility model is as follows:

[0034] During the assembly of the sphere and the tubular body, one end of the positioning pin is first embedded into the second positioning groove on the inner wall of the tubular body, and the elastic element in the second positioning groove is embedded into the limiting groove on the positioning pin. This allows the positioning pin to move radially into the second positioning groove along the tubular body by squeezing the elastic element until it is almost retracted into the second positioning groove on the inner wall of the tubular body.

[0035] Next, a sphere with an outer diameter slightly smaller than the inner diameter of the tubular body is inserted into the tubular body by clamping or other means, so that the first positioning groove on the sphere is aligned with the limiting groove in the second positioning groove. Under the action of the elastic element, the positioning pin moves out of the second positioning groove and embeds into the first positioning groove on the sphere.

[0036] Finally, the rotating handle with the protrusion is locked to the other side of the ball with the connecting groove by bolts, so that the rotating handle can drive the ball to rotate.

[0037] When the above-mentioned fluid switching valve is used, it can quickly open and close the fluid passage, facilitate the disassembly and installation of the ball, and reduce the gap between the ball and the inner wall of the tubular body, thereby improving the sealing performance when the fluid passage is closed.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. 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.
