Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a regulating valve and an energy storage device. Background Technology

[0002] Liquid-cooled electronic devices such as energy storage devices are usually equipped with a liquid cooling circulation system for heat dissipation. This system delivers coolant through coolant circulation pipelines, which are equipped with regulating valves to control the flow direction and flow rate of the coolant.

[0003] Please see Figure 1 The existing control valve consists of a valve body 1a and an actuator 4a. The drive shaft 41a of the actuator 4a is connected to the valve stem 2a of the valve body 1a. Rotation of the valve stem 2a drives the valve core inside the valve body 1a to rotate, thus achieving regulation. A PTFE (polytetrafluoroethylene) sealing ring 3a is typically used as the dynamic seal between the valve body 1a and the valve core. However, during long-term operation, the sealing ring 3a is prone to creep failure under high-temperature environments and undergoes continuous wear during regulation. This leads to potential leakage in the existing control valve, especially under high-pressure conditions. Utility Model Content

[0004] The purpose of this invention is to provide a regulating valve and an energy storage device, which aims to solve the problem of leakage that occurs easily in existing regulating valves.

[0005] To solve the above-mentioned technical problems, the present invention provides a regulating valve, comprising:

[0006] Valve body;

[0007] A valve stem, one end of which is rotatably inserted into the valve body, the valve stem having a valve stem drive end located outside the valve body;

[0008] A sealing sleeve, one end of which is fitted over the valve stem drive end and sealed to the valve body, the sealing sleeve being designed to be able to twist and deform along the rotation direction of the valve stem;

[0009] A sealing cap, wherein the sealing cap is disposed on the end of the sealing sleeve away from the valve body and is sealed to the sealing sleeve;

[0010] An actuator is located on the side of the sealing cover away from the valve stem drive end. The drive shaft of the actuator is oriented toward the sealing cover. The drive shaft is connected to the valve stem drive end through the sealing cover so that when the drive shaft rotates, it drives the valve stem to rotate through the sealing cover.

[0011] To achieve the above objectives, this utility model also provides an energy storage device, including a liquid cooling circulation system, wherein the above-mentioned regulating valve is provided on the coolant circulation pipeline of the liquid cooling circulation system.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The control valve of this invention has a sealing sleeve fitted around the valve stem drive end. One end of the sealing sleeve forms a static seal with the valve body, and the other end forms a static seal with the sealing cover. The actuator establishes a transmission relationship with the valve stem through the sealing cover, thus achieving a fully static sealing structure for the entire control valve, fundamentally avoiding the leakage risk associated with traditional dynamic sealing structures.

[0023] To address the leakage problem of existing control valves, this invention provides a control valve that can be used in liquid-cooled electronic devices such as energy storage equipment. Figure 2 A preferred embodiment of the regulating valve provided by this utility model is shown.

[0024] Please see Figure 2 In some embodiments, the regulating valve 100 includes a valve body 1, a valve stem 2, a sealing sleeve 3, a sealing cover 4, and an actuator 5; one end of the valve stem 2 is rotatably inserted into the valve body 1, and the valve stem 2 has a valve stem drive end 21 located outside the valve body 1; one end of the sealing sleeve 3 is sleeved outside the valve stem drive end 21 and is sealed to the valve body 1, and the sealing sleeve 3 is configured to be able to twist and deform along the rotation direction of the valve stem 2; the sealing cover 4 is covered on the end of the sealing sleeve 3 away from the valve body 1 and is sealed to the sealing sleeve 3; the actuator 5 is located on the side of the sealing cover 4 away from the valve stem drive end 21, and the drive shaft 51 of the actuator 5 is oriented towards the sealing cover 4. The drive shaft 51 and the valve stem drive end 21 are connected through the sealing cover 4 for transmission, so that when the drive shaft 51 rotates, the valve stem 2 is driven to rotate through the sealing cover 4.

[0025] Specifically, a valve cavity (not shown in the figure) is formed inside the valve body 1. One end of the valve stem 2 extends into the valve cavity of the valve body 1, and a valve core (not shown in the figure) is provided at the end of the valve stem 2 located in the valve cavity. Thus, the valve stem 2 can drive the valve core to rotate in both directions, thereby realizing the regulating function of the regulating valve 100. The axial direction of the valve stem 2 is defined as vertical, and the end of the valve stem 2 inserted into the valve body 1 is the lower end of the valve stem 2. The upper end of the valve stem 2 is located outside the valve body 1 and on the upper side of the valve body 1, so that the upper end of the valve stem 2 forms the valve stem drive end 21, and the valve stem 2 can drive the valve core to rotate along the vertical axis.

[0026] The sealing sleeve 3 is a cylindrical shape extending vertically. The lower end of the sealing sleeve 3 is fitted over the valve stem drive end 21 and connected to the valve body 1. A first static sealing structure 6 is provided between the lower end of the sealing sleeve 3 and the valve body 1, thus achieving a sealed connection between the lower end of the sealing sleeve 3 and the valve body 1. A sealing cap 4 is provided at the upper end of the sealing sleeve 3, and a second static sealing structure 7 is provided between the upper end of the sealing sleeve 3 and the sealing cap 4, thus achieving a sealed connection between the upper end of the sealing sleeve 3 and the sealing cap 4. Therefore, even if coolant enters the sealing sleeve 3 from the connection point between the lower end of the sealing sleeve 3 and the valve body 1, it cannot leak from the upper or lower end of the sealing sleeve 3.

[0027] The sealing sleeve 3 has a certain deformation capacity, allowing its upper end to twist relative to its lower end along the rotation direction of the valve stem 2. The specific configuration of the sealing sleeve 3 can be determined according to actual conditions. For example, the sealing sleeve 3 can be made of a material with deformation capacity to give it a certain degree of deformation capability. Optionally, please refer to... Figure 2 In some embodiments, the sealing sleeve 3 is a bellows, which enables the sealing sleeve 3 to have a certain deformation capability. The following will describe the sealing sleeve 3 as a bellows.

[0028] The actuator 5 is located above the sealing cover 4, with its drive shaft 51 facing downwards and vertically opposite to the sealing cover 4. The sealing cover 4 is connected to both the drive shaft 51 of the actuator 5 and the valve stem drive end 21 of the valve stem 2. Thus, the drive shaft 51 can drive the valve stem 2 to rotate in both directions via the sealing cover 4, and when the sealing cover 4 drives the valve stem 2 to rotate in both directions, the sealing sleeve 3 will also be torsional and deformed in both directions. Depending on the driving method of the regulating valve 100, the actuator 5 can be an electric actuator or a pneumatic actuator, etc. Optionally, please refer to [reference needed]. Figure 2 In some embodiments, actuator 5 is a motor, and the following description will take actuator 5 as a motor as an example.

[0029] The regulating valve 100 of this invention has a sealing sleeve 3 fitted over the valve stem drive end 21. One end of the sealing sleeve 3 forms a static seal with the valve body 11, and the other end forms a static seal with the sealing cover 4. The actuator 5 establishes a transmission relationship with the valve stem through the sealing cover 4. The entire regulating valve 100 thus achieves a fully static sealing structure, fundamentally avoiding the leakage risk caused by traditional dynamic sealing structures.

[0030] The specific configuration of valve body 1 can be set according to actual conditions. The structural design of valve body 1 is related to the type of control valve 100. For example, control valve 100 can be a ball valve or a butterfly valve, etc. Optionally, please refer to... Figure 2 In some embodiments, the regulating valve 100 is a ball valve.

[0031] Similarly, the regulating valve 100 can be a two-way valve or a three-way valve, etc. Alternatively, please refer to... Figure 2 In some embodiments, the valve body 1 is provided with a valve cavity, and the valve body 1 is provided with a valve body inlet (not shown in the figure), a first valve body outlet (not shown in the figure), and a second valve body outlet (not shown in the figure) communicating with the valve cavity; the valve stem 2 is inserted into the valve cavity at one end away from the sealing cover 4 and is provided with a valve core, and the valve core is provided with a valve core channel; when the valve stem 2 is in the first position, the valve body inlet and the first valve body outlet are connected through the valve core channel; when the valve stem 2 is in the second position, the valve body inlet and the second valve body outlet are connected through the valve core channel.

[0032] Specifically, the regulating valve 100 is a three-way valve. The actuator 5 and the valve body 1 are sealed by the end face of the sealing sleeve 3. The valve stem drive end 21 of the valve stem 2 is sealed inside the sealing sleeve 3. The flow switching of the regulating valve 100 is achieved by the rotation of the sealing sleeve 3. The following will take the regulating valve 100 as a three-way valve as an example for introduction.

[0033] A first static sealing structure 6 is provided between the lower end of the sealing sleeve 3 and the valve body 1. Optionally, please refer to [link to relevant documentation]. Figure 2 In some embodiments, a first flange (not shown in the figure) is provided at one end of the sealing sleeve 3 near the valve body 1, and a first static sealing structure 6 is provided between the first flange and the valve body 1.

[0034] Specifically, the lower end of the sealing sleeve 3 is provided with a first flange, and the valve body 1 is usually provided with a lower flange (not shown in the figure). The first flange on the sealing sleeve 3 and the lower flange on the valve body 1 are connected vertically, and a first static sealing structure 6 is provided between the first flange and the lower flange. The first static sealing structure 6 can be a sealing ring, a sealing gasket, or a sealant, etc.

[0035] A second static sealing structure 7 is provided between the upper end of the sealing sleeve 3 and the sealing cover 4. Optionally, please refer to [link / reference needed]. Figure 2In some embodiments, a second flange (not shown in the figure) is provided at one end of the sealing sleeve 3 near the sealing sleeve 3, and a second static sealing structure 7 is provided between the second flange and the sealing cover 4.

[0036] Specifically, a second flange is provided at the upper end of the sealing sleeve 3. The sealing sleeve 3 is usually provided with an upper flange (not shown in the figure). The second flange on the sealing sleeve 3 is connected to the upper flange on the sealing sleeve 3. A second static sealing structure 7 is provided between the second flange and the upper flange. The second static sealing structure 7 can be a sealing ring, a sealing gasket, or a sealant, etc.

[0037] The drive shaft 51 of actuator 5 is connected to the sealing cover 4 via a transmission connection. Optionally, please refer to [link to relevant documentation]. Figure 2 In some embodiments, the middle part of the sealing cover 4 is recessed towards the valve stem drive end 21 to form a recessed groove 41 in the recessed part of the sealing cover 4. One end of the drive shaft 51 near the valve stem drive end 21 extends into the recessed groove 41. A limiting structure (not shown in the figure) is provided between the groove sidewall of the recessed groove 41 and the peripheral sidewall of the drive shaft 51 to limit the drive shaft 51 and the sealing cover 4 in the rotation direction of the valve stem 2.

[0038] Specifically, the middle part of the sealing cover 4 is recessed downward relative to the adjacent part, so as to form an upward-facing recessed groove 41 on the upper surface of the sealing cover 4. The lower end of the drive shaft 51 extends downward into the recessed groove 41 from the groove opening, and there is a limiting structure between the peripheral side of the lower end of the drive shaft 51 and the groove sidewall of the recessed groove 41. The limiting structure can limit the drive shaft 51 and the sealing cover 4 in the rotation direction of the valve stem 2, so as to restrict the drive shaft 51 from rotating relative to the sealing cover 4 along the vertical axis. Thus, when the drive shaft 51 rotates, under the action of the limiting structure, the drive shaft 51 can drive the sealing cover 4 to rotate together.

[0039] The specific setting of the limiting structure can be set according to the actual situation. For example, the limiting structure may include a limiting key set between the lower end of the drive shaft 51 and the groove side wall of the recessed groove 41, and a keyway set between the lower end of the drive shaft 51 and the groove side wall of the recessed groove 41. The limiting key is located in the keyway, thereby limiting the drive shaft 51 and the sealing cover 4 in the rotation direction of the valve stem 2.

[0040] Optionally, in some embodiments, the limiting structure includes a first limiting plane (not shown in the figure) disposed on the peripheral side of the drive shaft 51 and a second limiting plane (not shown in the figure) disposed on the groove sidewall of the recessed groove 41, wherein the first limiting plane and the second limiting plane are in contact.

[0041] Specifically, the lower end of the drive shaft 51 has a cross-section in the shape of a triangle, square, or trapezoid, thus forming a first limiting plane on the lower peripheral surface of the drive shaft 51. The shape of the recessed groove 41 is adapted to the shape of the lower end of the drive shaft 51, thus forming a second limiting plane on the side wall of the recessed groove 41. The second limiting plane is in close contact with the first limiting plane, thereby limiting the drive shaft 51 and the sealing cover 4 in the rotation direction of the valve stem 2.

[0042] Optionally, please refer to Figure 2 In some embodiments, the end face of the drive shaft 51 abuts against the surface of the bottom wall of the recessed groove 41 away from the valve body 1. The lower end face of the drive shaft 51 abuts against the upper surface of the bottom wall of the recessed groove 41, thereby enabling the actuator 5 and the sealing cover 4 to be installed and positioned vertically and upward.

[0043] The valve stem drive end 21 is connected to the sealing cover 4 via a transmission connection. The valve stem drive end 21 can be fixed to the sealing cover 4 by welding or screw fixing, so that the sealing cover 4 can drive the valve stem 2 to rotate in both directions. Alternatively, the valve stem drive end 21 can be connected to the sealing cover 4 by setting a circumferential limiting structure between the valve stem drive end 21 and the sealing cover 4. The circumferential limiting structure limits the valve stem drive end 21 and the sealing cover 4 in the rotation direction of the valve stem 2, so that the sealing cover 4 can drive the valve stem 2 to rotate in both directions.

[0044] Optionally, please refer to Figure 2 In some embodiments, the end face of the valve stem drive end 21 abuts against the bottom wall of the recessed groove 41 near the surface of the valve body 1. The upper end face of the valve stem 2 abuts against the lower surface of the bottom wall of the recessed groove 41, thus enabling the valve stem 2 and the sealing cover 4 to be installed and positioned vertically.

[0045] The regulating valve 100 is a high-sealing, leak-proof three-way valve. The sealing method of the regulating valve 100 is not too complicated, the manufacturing cost is low, and it is suitable for mass production. The sealing performance of the regulating valve 100 is significantly improved by sealing the valve stem 2 in the sealing sleeve 3. The end face sealing between the sealing sleeve 3 and the valve body 1 and the actuator 5 can effectively prevent leakage of the regulating valve 100 due to high and low temperatures.

[0046] This utility model also provides an energy storage device, which is a liquid-cooled electronic device. The energy storage device includes a liquid-cooled circulation system, and a regulating valve is provided on the coolant circulation pipeline of the liquid-cooled circulation system.
