[0008] Specifically, when the driving member drives the second valve core assembly, the second guide plate, and the actuating member to move along the axial direction of the second valve tube to a preset distance, the actuating member causes the second valve tube to be fully opened or fully closed.

[0009] Specifically, the first valve tube and the second valve tube are sealed together.

[0010] Specifically, the valve body device further includes a fixing component for fixing the first valve body terminal and the second valve body terminal.

[0024] Specifically, a transmission structure is provided between the actuating member and the valve disc of the second valve core assembly. When the actuating member rotates relative to the second valve tube, the actuating member causes the valve disc of the second valve core assembly to rotate through the transmission structure.

[0033] Specifically, the piston-type inner tube includes a first inner tube and a second inner tube connected at one end to the first inner tube. The outer diameter of the first inner tube is larger than the outer diameter of the second inner tube. A stepped tube is provided inside the second valve tube. The stepped tube has a stepped hole coaxial with the second valve tube. The outer side of the first inner tube mates with the inner sidewall of the second valve tube, and the outer side of the second inner tube mates with the stepped hole.

[0038] Align the first valve body with the second valve body and insert it toward the second valve tube;

[0039] The first valve body terminal drives the actuating member, and the actuating member drives the valve discs of the second valve core assembly to move closer or further apart along the second guide rail to close or open the second valve tube;

[0040] The disengagement step includes:

[0041] Pulling the first valve body away from the second valve body resets the valve disc of the second valve core assembly, and closes the second valve tube.

[0042] The present invention provides a valve body device, a cooling system, and a method of using the valve body device. When the second valve body is connected to the first valve body, the actuating component drives the valve disc of the second valve core assembly to open the second valve body. At the same time, the valve disc of the second valve core assembly can drive the valve disc of the first valve core assembly to open the first valve body. This can effectively prevent the first valve body and the second valve body from dripping or leaking liquid when connected, disconnected, or after disconnection, and has good reliability.

[0066] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0067] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0068] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0069] This invention provides a valve body device, such as... Figure 1 and Figures 8 to 10 As shown, the device includes a first valve body terminal 100 and a second valve body terminal 200. The second valve body terminal 200 includes a second valve tube 210, a second valve core assembly 220, a second guide disk 240, and an actuating member 250. The second valve core assembly 220 is disposed within the second valve tube 210, or the second valve core assembly 220 at least partially protrudes from the second valve tube 210. The actuating member 240 is disposed within the second valve tube 210. The second valve core assembly 220 includes at least two valve discs 230. The second guide disk 220 is provided with a second guide rail 244. The first valve body terminal 100 is used to drive the actuating member 250. The actuating member 250 drives the valve discs 230 to move closer or further apart along the second guide rail 244 to close or open the second valve tube 210. This design has high structural reliability and can close or open the second valve tube 210 more quickly and reliably by simultaneously driving each valve disc 230.

[0070] Specifically, the second guide plate 240 can be disposed inside or outside the second valve tube 210.

[0071] Specifically, the first valve body terminal 100 drives the second valve core assembly 220, the second guide disk 240, and the actuating member 250 to move axially along the second valve tube 210, and pushes the actuating member 250 to move circumferentially along the second valve tube 210, so as to drive the valve disc 230 to move closer or further away from each other along the second guide rail 244.

[0072] Specifically, the first valve body terminal 100 includes a first valve tube 110 and a driving member. The driving member is disposed in the first valve tube 110 and is used to drive the second valve core assembly 220, the second guide disk 240 and the actuating member 250 to move axially along the second valve tube 210, and to push the actuating member 250 to move circumferentially along the second valve tube 210. It can use the insertion action of the first valve body terminal 100 to drive the second valve core assembly 220, the second guide disk 240 and the actuating member 250 to move axially along the second valve tube 210, which is simple and reliable to operate.

[0073] Specifically, when the driving member drives the second valve core assembly 220, the second guide plate 240 and the actuating member 250 to move along the axial direction of the second valve tube 210 to a preset distance, the actuating member 250 causes the second valve tube 210 to be fully opened or fully closed, resulting in a good opening and closing effect.

[0074] Specifically, the first valve tube 110 and the second valve tube 210 are plugged into each other and sealed together, which makes them easy to operate and highly reliable.

[0075] In practical applications, the valve disc 130 can move in various ways. Multiple valve discs 130 may move simultaneously to open or close the first valve tube 110, or one (partial) valve disc 130 may remain stationary while another (partial) valve disc 130 moves to open or close the first valve tube 110. The valve disc 130 can also close the first valve tube 110 when it is moving away, and it can also open the first valve tube 110 when it is moving closer. The specific design can be tailored to actual needs.

[0076] Specifically, the first guide plate 140 can be disposed inside the first valve tube 110 or outside the first valve tube 110.

[0077] Specifically, the valve body device further includes a fixing component for fixing the first valve body terminal 100 and the second valve body terminal 200.

[0078] Specifically, the driving component includes a first valve core assembly 120 and a first guide disk 140; the first valve core assembly 120 is disposed inside the first valve tube 110, or at least partially disposed outside the first valve tube 110, the first valve core assembly 120 includes at least two valve discs 130, the first guide disk 140 is provided with a first guide rail, and multiple valve discs 130 move closer or further away from each other along the first guide rail to close or open the first valve tube 110; the driving component drives the second valve core assembly 220 to move, thereby driving the first valve core assembly 120 and the second valve core assembly 220 to move in tandem, so as to realize the synchronous closing or opening of the first valve tube 110 and the second valve tube 220, which is ingenious in structure.

[0079] Specifically, such as Figures 19 to 22 As shown, in one possible implementation, the first valve core assembly 120 includes two valve discs 130, and the second valve core assembly 220 includes two valve discs 230. The first guide rail and the second guide rail 244 can be linear guide rails. The two valve discs 130 of the first valve core assembly 120 and the two valve discs 230 of the second valve core assembly 220 move linearly along the first guide rail and the second guide rail 244 respectively, and the operation is simple and reliable.

[0080] Specifically, such as Figures 1 to 18 As shown, the first valve body terminal 100 also includes a third valve core assembly 330, which includes at least two valve discs 331. The at least two valve discs 331 move closer to or further away from each other along the first guide rail. The at least two valve discs 331 of the third valve core assembly 330 move synchronously with the two valve discs 130 of the first valve core assembly 120 to close or open the first valve tube 110.

[0081] Specifically, the second valve body terminal 200 further includes a fourth valve core assembly 340, which includes at least two valve discs 341. The at least two valve discs 341 move closer to or further away from each other along the second guide rail 244. The at least two valve discs 341 of the fourth valve core assembly 340 move synchronously with the two valve discs 230 of the second valve core assembly 220 to close or open the second valve tube 110.

[0082] Specifically, the second valve body 200 has a second flow channel 201, and the second valve core assembly 220 is connected to the second valve tube 210 and is used to control the opening and closing of the second flow channel 201. Each second valve core assembly 220 includes at least two valve discs 230. The valve discs 230 of the second valve core assembly can be driven by the first valve body 100 connected to the second valve body 200. In this way, the insertion of the first valve body 100 causes the valve discs 230 of the second valve core assembly to move and open, so that the second valve body 200 is open, which can prevent dripping and leakage, and its structure has good reliability.

[0083] Specifically, the second valve core assembly 220 includes a second guide disk 240, which is fixedly connected to or integrally formed within the second valve tube 210. The valve disc 230 of the second valve core assembly is rotatably or slidably connected to the second guide disk 240. In this embodiment, the outer periphery of the second guide disk 240 is in contact with the inner wall of the first valve tube 110. The second guide disk 240 has a second valve hole 241, and the opening and closing of the second valve hole 241 determines the opening and closing of the first valve body 100. The second valve core assembly 220 has at least two valve discs 230, which are rotatably or slidably connected to the second guide disk 240. The valve discs 230 of the second valve core assembly 220 can rotate or slide to a closed state to block the second valve hole 241. By controlling the valve discs 230 of the second valve core assembly 220 to rotate (or slide) to an open state or a closed state, the second valve hole 241 can be opened or closed. In this embodiment, the valve disc 230 of the second valve core assembly 220 is rotatably connected to the second guide disk 240.

[0084] In practical applications, the valve disc 230 can move in various ways. Multiple valve discs 230 may move simultaneously to open or close the second valve tube 210, or one (partial) valve disc 230 may remain stationary while another (partial) valve disc 230 moves to open or close the second valve tube 210. The valve disc 230 can also close the second valve tube 210 when it is moving away, and it can also open the second valve tube 210 when it is moving closer. The specific design can be tailored to actual needs.

[0085] Specifically, the valve discs 230 of each of the second valve core assemblies 220 are mechanically connected to the second guide disc 240 in an iris-like manner, which provides excellent reliability.

[0086] Specifically, the second valve body 200 further includes an actuating member 250 movably connected to the second valve tube 210 and driven by the first valve body 100, the actuating member 250 being used to drive the valve disc 230 of the second valve core assembly 220.

[0087] Specifically, a sliding drive structure is provided between the actuating member 250 and the second valve tube 210. When the actuating member 250 slides along the axial direction of the second valve tube 210, the sliding member rotates by means of the sliding drive structure. That is, by utilizing the insertion driving force of the first valve body 100 being inserted into the second valve body 200 during docking, the sliding member rotates circumferentially while sliding axially. No electrical control is required, making the application more convenient.

[0088] Specifically, such as Figures 8 to 14 As shown, the actuating component 250 includes a movable disk, and the sliding drive structure includes a sliding guide portion 251 disposed on the outer periphery of the movable disk and a guide groove 211 disposed on the inner wall of the second valve tube 210. The sliding guide portion 251 extends into the guide groove 211, so that the linear sliding of the sliding component can be converted into linear sliding and circumferential rotation. In this way, the sliding component drives the valve disc 230 of the second valve core assembly 220 to rotate synchronously through rotation, and the valve disc 230 of the second valve core assembly 220 drives the valve disc 130 of the first valve core assembly 120 to rotate synchronously.

[0089] Specifically, such as Figure 14 As shown, the guide groove 211 can be an inclined groove, a spiral groove, or an arc groove, etc., which can convert the linear motion of the actuating component 250 into linear sliding and circumferential rotation.

[0090] Specifically, such as Figures 8 to 14 As shown, at least two sliding guide sections 251 are provided, each sliding guide section 251 being evenly distributed along the outer circumference of the movable disk; at least two sets of guide grooves 211 are provided, and the number of guide grooves 211 is equal to that of the sliding guide sections 251, each guide groove 211 being evenly distributed along the inner circumference of the second valve pipe 210. In this embodiment, two sliding guide sections 251 are symmetrically arranged, and two sets of guide grooves 211 are symmetrically arranged.

[0091] Specifically, such as Figures 8 to 14 As shown, the sliding guide 251 is connected to a fixed pulley 252, which extends into the guide groove 211. The fixed pulley 252 can be a bearing or the like, which can make the sliding and rotation of the actuating component 250 smoother.

[0092] Specifically, such as Figures 8 to 14 As shown, an anti-rotation structure is provided between the second guide plate 240 and the second valve tube 210, so that the second guide plate 240 can only slide along the axial direction of the second valve tube 210 and cannot rotate circumferentially with the actuating member 250. When the first valve body 100 and the second valve body 200 are connected, the first valve body 100 can directly act on the second valve core assembly 220, and indirectly push the actuating member 250 by pushing the second valve core assembly 220. When the actuating member 250 rotates, it drives the valve disc 230 of the second valve core assembly 220 to rotate relative to the second guide plate 240.

[0093] Specifically, such as Figures 8 to 14 As shown, the anti-rotation structure includes an anti-rotation groove 212 disposed on the inner wall of the second valve tube 210 and an anti-rotation protrusion 243 disposed on the outer periphery of the second guide plate 240. The anti-rotation groove 212 is disposed along the axial direction of the second valve tube 210, and the anti-rotation protrusion 243 extends into the anti-rotation groove 212. Two anti-rotation grooves 212 and two anti-rotation protrusions 243 can be provided respectively. The inner wall of the second valve tube 210 can be provided with an assembly groove 213. One end of the assembly groove 213 is connected to the end of the second valve tube 210, and the other end of the assembly groove 213 is connected to the guide groove 211 to facilitate assembly. The assembly groove 213 can be L-shaped. In this embodiment, the assembly groove 213 includes a longitudinal groove and a transverse groove. The longitudinal groove is disposed along the axial direction of the second valve tube 210, and the starting end of the longitudinal groove is connected to the end of the second valve tube 210. The transverse groove is perpendicularly connected to the longitudinal groove, and the two ends of the transverse groove are respectively connected to the end of the longitudinal groove and the starting end of the guide groove 211. One end of the anti-rotation groove 212 can be connected to the transverse groove of the guide groove 211 or the assembly groove 213.

[0094] Specifically, when the actuating member 250 rotates in the forward direction, it drives the transmission rod 261 to slide along the second guide rail 244 in the second direction through the drive groove 253, causing the valve disc 230 of the second valve core assembly 220 to rotate in the direction of blocking the second valve hole 241; when the actuating member 250 rotates in the reverse direction, it drives the transmission rod 261 to slide along the second guide rail 244 in the first direction through the drive groove 253, causing the valve disc 230 of the second valve core assembly 220 to rotate in the direction of opening the second valve hole 241.

[0095] Specifically, the valve body device further includes a fixing component for fixing the second valve body 200 and the first valve body 100 so that the second valve body 200 and the first valve body 100 are kept in contact. The fixing component may use a double-headed pipe clamp, pipe sleeve, buckle or other structure to keep the second valve body 200 and the first valve body 100 fixedly connected.

[0096] Specifically, at least two second valve core assemblies 220 are provided, each second valve core assembly 220 is spaced apart along the axial direction of the second valve tube 210, and the valve discs 230 of the second valve core assembly 220 of each second valve core assembly 220 can operate synchronously.

[0097] Specifically, the valve disc 230 of the second valve core assembly 220 is provided with a linkage structure for linkage with the valve disc 130 of the first valve core assembly 120 of the first valve body 100. The linkage structure can be a plug-in type.

[0098] like Figures 1 to 17As shown, when the first valve body 100 and the second valve body 200 are connected, the first valve body 100 can drive the valve disc 230 of the second valve core assembly 220 of the second valve body 200; when the first valve body 100 and the second valve body 200 are connected, fluid can flow through the first valve body 100 and the second valve body 200.

[0099] Specifically, the first valve body 100 includes a first valve tube 110 for driving the valve disc 230 of the second valve core assembly 220, and the first valve tube does not contain a valve core assembly; that is, the first valve body 100 is only used to directly or indirectly drive the valve disc 230 of the second valve core assembly 220. Alternatively, the first valve body 100 includes a first valve tube 110, and at least one first valve core assembly 120 is disposed within the first valve tube 110. The first valve core assembly 120 includes a first guide plate 140 and a valve disc 130 of the first valve core assembly 120 driven by the valve disc 230 of the second valve core assembly 220. The first guide plate 140 is fixedly connected to or integrally formed within the first valve tube 110, and the valve disc 130 of the first valve core assembly 120 is connected to the first guide plate 140.

[0100] The first valve body 100 has a first flow channel 101. The first valve body 100 includes a first valve tube 110 and a first valve core assembly 120 connected to the first valve tube 110. The first valve core assembly 120 can be used to control the opening and closing of the first flow channel 101. The first valve core assembly 120 includes a valve disc 130. The valve disc 130 of the first valve core assembly 120 can be driven by the second valve body 200 when it is docked with the first valve body 100, so as to open the first flow channel 101. That is, the first valve body 100 and the second valve body 200 are docked to drive the valve disc 130 of the first valve core assembly 120 to open the first flow channel 101.

[0101] like Figures 8 to 10As shown, the second valve body 200 has a second flow channel 201. The second valve body 200 includes a second valve tube 210 and a second valve core assembly 220 connected to the second valve tube 210. The second valve core assembly 220 can be used to control the opening and closing of the second flow channel 201. The second valve core assembly 220 includes an actuating member 250 connected to the second valve pipe 210 and driven by the first valve body 100. The second valve core assembly 220 also includes a valve disc 230 driven by the actuating member 250 to open the second flow channel 201. When the second valve body 200 is connected to the first valve body 100, the valve disc 230 of the second valve core assembly 220 can drive the valve disc 130 of the first valve core assembly 120 of the first valve body 100. When the first valve body 100 is connected to the second valve body 200, the valve disc 130 of the first valve core assembly 120 is driven by the valve disc 230 of the second valve core assembly 220 of the second valve body 200. Thus, when the first valve body 100 and the second valve body 200 are not connected, both the first valve core assembly 120 and the second valve core assembly 220 are in a closed state, and neither the first valve body 100 nor the second valve body 200 is connected, preventing leakage. Figures 11 to 13 As shown, when the first valve body 100 and the second valve body 200 are connected, the insertion of the first valve body 100 drives the actuating member 250, which in turn drives the valve disc 230 of the second valve core assembly 220 to open, thus opening the second valve body 200. Moreover, at the same time as the valve disc 230 of the second valve core assembly 220 moves, the valve disc 230 of the second valve core assembly 220 drives the valve disc 130 of the first valve core assembly 120 to open synchronously, thus opening the first valve body 100 simultaneously. During the process of separating the first valve body 100 from the second valve body 200, i.e., during the process of pulling out the pipeline, the first valve body 100 releases the drive of the actuating member 250, and the actuating member 250 reverses its action. This causes the actuating member 250 to drive the valve disc 230 of the second valve core assembly 220 to reverse its action and switch from the conducting state to the closed state. Moreover, at the same time as the valve disc 230 of the second valve core assembly 220 reverses its action, the valve disc 230 of the second valve core assembly 220 drives the valve disc 130 of the first valve core assembly 120 to switch from the conducting state to the closed state simultaneously, so that the first valve body 100 closes at the same time. This can effectively prevent the first valve body 100 and the second valve body 200 from dripping or leaking liquid when docking, when separating, and after separation, and has good reliability.

[0102] Specifically, such as Figures 1 to 7As shown, the first guide plate 140 can be assembled inside the first valve tube 110, or the first guide plate 140 can be integrally formed inside the first valve tube 110. In this embodiment, the outer periphery of the first guide plate 140 is in contact with the inner wall of the first valve tube 110, and the first guide plate 140 has a first valve hole 141. The opening and closing of the first valve hole 141 determines the opening and closing of the first valve body 100. The valve discs 130 of the first valve core assembly 120 are provided with at least two and are rotatably or slidably connected to the first guide plate 140. The valve discs 130 of the first valve core assembly 120 can rotate or slide to a closed state to block the first valve hole 141. By controlling the valve discs 130 of the first valve core assembly 120 to rotate (or slide) to a conducting state or a closed state, the first valve hole 141 can be opened or closed. In this embodiment, the valve discs 130 of the first valve core assembly 120 are rotatably connected to the first guide plate 140.

[0103] Specifically, a first sealing gasket 142 may be provided between the first guide plate 140 and the valve disc 130 of the first valve core assembly 120 to ensure sealing.

[0104] Specifically, such as Figures 8 to 13 As shown, the second valve core assembly 220 also includes a second guide disk 240. The second guide disk 240 can be assembled inside the second valve tube 210, or it can be integrally formed inside the second valve tube 210. In this embodiment, the outer periphery of the second guide disk 240 is in contact with the inner wall of the first valve tube 110. The second guide disk 240 has a second valve hole 241. The opening and closing of the second valve hole 241 determines the opening and closing of the first valve body 100. The valve discs 230 of the second valve core assembly 220 are provided with at least two and are rotatably or slidably connected to the second guide disk 240. The valve discs 230 of the second valve core assembly 220 can rotate or slide to a closed state to block the second valve hole 241. By controlling the valve discs 230 of the second valve core assembly 220 to rotate (or slide) to an open state or a closed state, the second valve hole 241 can be opened or closed. In this embodiment, the valve discs 230 of the second valve core assembly 220 are rotatably connected to the second guide disk 240.

[0105] Specifically, a second sealing gasket 242 may be provided between the second guide plate 240 and the valve disc 230 of the second valve core assembly 220 to ensure sealing.

[0106] Specifically, a transmission structure is provided between the actuating member 250 and the second valve core assembly 220. When the actuating member 250 rotates relative to the second valve tube 210, the actuating member 250 causes the valve disc 230 of the second valve core assembly 220 to rotate synchronously through the transmission structure, so that the second valve body 200 can be opened and closed.

[0107] Specifically, a linkage structure is provided between the first valve core assembly 120 and the second valve core assembly 220. When the first valve body 100 and the second valve body 200 are connected, the valve disc 230 of the second valve core assembly 220 and the valve disc 130 of the first valve core assembly 120 are connected through the linkage structure and move synchronously, so that the first valve body 100 and the second valve body 200 can be opened and closed at the same time.

[0108] Specifically, such as Figures 1 to 17 As shown, the valve discs 230 of each second valve core assembly 220 are connected to the second guide disk 240 via a rotating shaft 231. The transmission structure includes a transmission rod 261 for driving the valve discs 230 of the second valve core assembly 220 to swing around the rotating shaft 231. The valve discs 230 of the second valve core assembly 220 are configured with a mechanical iris, which can effectively seal the second valve orifice 241. Each valve disc 230 of the second valve core assembly 220 is connected to a transmission rod 261, and each transmission rod 261 is connected to an actuating member 250, which allows the valve discs 230 of each second valve core assembly 220 to swing synchronously around the rotating shaft 231 to seal or open the second valve orifice 241. The valve discs 130 of the first valve core assembly 120 can adopt the same or similar structure as the valve discs 230 of the second valve core assembly 220. In specific applications, the valve disc 130 of the first valve core assembly 120 and the valve disc 230 of the second valve core assembly 220 can be the same (general).

[0109] Specifically, the actuating component 250 is provided with a drive groove 253, and the second guide plate 240 is provided with a second guide rail 244; one end of the transmission rod 261 is rotatably connected to the valve disc 230 of the second valve core assembly 220, the transmission rod 261 passes through the second guide rail 244, and the other end of the transmission rod 261 extends into the drive groove 253. The projection of the second guide rail 244 and the drive groove 253 in the axial direction of the second valve body 200 intersects. When the actuating component 250 rotates, under the action of the drive groove 253 and the second guide rail 244, the transmission rod 261 slides along a preset trajectory.

[0110] Specifically, when the actuating member 250 rotates in the forward direction, it drives the transmission rod 261 to slide along the second guide rail 244 in the second direction through the drive groove 253, causing the valve disc 230 of the second valve core assembly 220 to rotate in the direction of blocking the second valve hole 241; when the actuating member 250 rotates in the reverse direction, it drives the transmission rod 261 to slide along the second guide rail 244 in the first direction through the drive groove 253, causing the valve disc 230 of the second valve core assembly 220 to rotate in the direction of opening the second valve hole 241.

[0111] Specifically, such as Figure 15 , Figure 16As shown, the drive groove 253 can be arc-shaped, the second guide rail 244 can be arc-shaped, and the projections of the drive groove 253 and the second guide rail 244 in the axial direction of the second valve body 200 intersect in opposite directions; in this embodiment, the second guide rail 244 is a through groove, and the drive groove 253 is a blind groove.

[0112] Specifically, when there are two or more first valve core assemblies 120, the valve discs 130 of each first valve core assembly 120 can be connected by a synchronizing rod 161, so that each first valve core assembly 120 can open or close synchronously. The valve disc 130 of the first valve core assembly 120 at the front end of the first valve body 100 is a first linkage valve core component.

[0113] Specifically, when there are two or more second valve core assemblies 220, the valve discs 230 of each second valve core assembly 220 can be connected via transmission rods, allowing each second valve core assembly 220 to open or close synchronously. In this embodiment, both sides of the actuating member 250 are provided with drive grooves 253. There are two second valve core assemblies 220, and the valve discs 230 of the two second valve core assemblies 220 are respectively connected to the drive grooves 253 on both sides of the actuating member 250 via transmission rods. The valve disc 230 of the second valve core assembly 220 at the front end of the second valve body 200 is a second linkage valve core component. The linkage structure is provided on the first linkage valve core component and the second linkage valve core component. When the first valve body 100 and the second valve body 200 are docked, the first linkage valve core component and the second linkage valve core component approach each other and dock through the linkage structure, allowing each second valve core assembly 220 to open or close synchronously. The linkage structure can adopt a plug-in mating structure.

[0114] Specifically, the linkage structure includes an insertion hole 171 disposed in each of the first linkage valve core components and a linkage insertion shaft 271 disposed in each of the second linkage valve core components and capable of being inserted into the insertion hole 171; or, the linkage structure includes an insertion hole 171 disposed in each of the second linkage valve core components and a linkage insertion shaft 271 disposed in each of the first linkage valve core components and capable of being inserted into the insertion hole 171. In this embodiment, each first linkage valve core component is provided with an insertion hole 171, and each second linkage valve core component is provided with a linkage insertion shaft 271. The front end of the linkage insertion shaft 271 may be provided with a rounded corner or a chamfer to facilitate insertion. When the first valve body 100 and the second valve body 200 are docked, each linkage insertion shaft 271 can be inserted into the insertion hole 171 respectively, so that the first valve core assembly 120 of the first valve body 100 can be linked with the second valve core assembly 220 of the second valve body 200.

[0115] Specifically, the second valve body 200 also includes an inner tube component for driving the second valve core assembly 220 to return to its original position along the axial direction of the second valve tube 210. The inner tube component includes a piston-type inner tube 281 and an elastic element 282. The piston-type inner tube 281 is disposed inside the second valve tube 210 and can slide along the axial direction of the second valve tube 210. The elastic element 282 is connected to the piston-type inner tube 281 and can be a spring. With this arrangement, when the first valve body 100 is pulled out of the second valve body 200, the second valve core assembly 220 and the actuating member 250 can be reset in time.

[0116] Specifically, the piston-type inner tube 281 includes a first inner tube 288 and a second inner tube 289 connected at one end to the first inner tube 288. The outer diameter of the first inner tube 288 is larger than the outer diameter of the second inner tube 289. A stepped tube 218 is provided inside the second valve tube 210. The stepped tube 218 has a stepped hole 219 coaxial with the second valve tube 210. The outer side of the first inner tube 288 is engaged with the inner sidewall of the second valve tube 210, and the outer side of the second inner tube 289 is engaged with the stepped hole 219. One end of the elastic member 282 abuts against the first inner tube 288, and the other end of the elastic member 282 abuts against the stepped tube 218. The elastic member 282 will not come into contact with the liquid.

[0117] Specifically, a sealing ring 283 is fitted around the outer periphery of the first inner tube to prevent leakage and improve the sealing effect.

[0118] Specifically, there are two second valve core assemblies 220. Each second valve core assembly 220 includes five valve discs 230. The valve discs 230 of each second valve core assembly 220 are arranged in the circumferential direction and are mechanically iris-shaped and rotatably connected to the second guide disk 240.

[0119] Specifically, there may be two first valve core assemblies 120. Each first valve core assembly 120 includes five valve discs 130. The valve discs 130 of each first valve core assembly 120 are arranged in the circumferential direction and are mechanically iris-shaped and rotatably connected to the first guide plate 140.

[0120] Specifically, a linkage structure is provided between the valve disc 230 of the second valve core assembly 220 and the valve disc 130 of the first valve core assembly 120. When the second valve body 200 and the first valve body 100 are docked, the valve disc 230 of the first valve core assembly and the valve disc 130 of the second valve core assembly are connected through the linkage structure and move synchronously.

[0121] Specifically, the valve discs 130 of the first valve core assembly 120 consist of multiple discs rotatably connected to the first guide plate 140. Each valve disc 130 of the first valve core assembly 120 can rotate towards the center of the first valve hole 141 and interlock to seal the first valve hole 141. Furthermore, each valve disc 130 of the first valve core assembly 120 can rotate in the opposite direction to reset and allow the first valve hole 141 to open. This design utilizes the principle of a mechanical iris and is applied to the control of liquid valves, resulting in good performance. Each disc is assembled to its corresponding guide plate using a mechanical iris-type connection structure.

[0122] Specifically, the valve discs 230 of the second valve core assembly 220 are multiple discs rotatably connected to the second guide disk 240. Each valve disc 230 of the second valve core assembly 220 can rotate towards the center of the second valve hole 241 and interlock to seal the second valve hole 241. Furthermore, each valve disc 230 of the second valve core assembly 220 can rotate in the opposite direction to reset, allowing the second valve hole 241 to open. The valve disc 130 of the first valve core assembly 120 can adopt the same structural design as the valve discs 230 of the second valve core assembly 220.

[0123] Specifically, such as Figure 18 As shown, the petals have a ladder-like structure for multi-faceted contact with adjacent petals, and the adjacent petals are partially overlapped, resulting in a good sealing effect.

[0124] Specifically, such as Figure 18 As shown, the flap includes a first layer of flap 310 and a second layer of flap 320 arranged vertically. The second layer of flap 320 is provided with a rotating connecting shaft. The first layer of flap 310 is offset to one side of the axis of the rotating connecting shaft by a set angle to form a trapezoidal structure with the second layer of flap 320. It has good sealing effect and good resistance to liquid impact.

[0125] Specifically, a sealing elastic layer 330 is provided on the side of the first layer 310 and / or the second layer 320. The sealing elastic layer 330 may be a rubber layer, which can further improve the reliability of the seal.

[0126] Specifically, the number of petals in the first valve core assembly 120 is equal to the number of petals in the second valve core assembly 220, and the structural shape of each petal in the first valve core assembly 120 is the same as that of each petal in the second valve core assembly 220, thus exhibiting high versatility.

[0127] Specifically, the first valve tube 110 and the second valve tube 120 can adopt a plug-in structure, that is, the front end of the first valve tube 110 can be inserted into the front end of the second valve tube 120.

[0128] In this embodiment, each first valve core assembly 120 and each second valve core assembly 220 includes 5 petals, and the maximum rotation angle of the petals can be 52 degrees. Of course, in specific applications, the number of petals and the maximum rotation angle can also be set according to the actual situation.

[0129] In practical applications, a return spring or spring can be connected to the leaflet to reset it under the action of the return spring or spring. Of course, a return spring or spring can also be omitted.

[0130] In practical applications, the opening and closing process of the valve discs takes place within the valve tubes (first valve tube 110, second valve tube 120) to avoid side leakage and internal leakage. Specifically, the inner tubes of the first valve tube 110 and the second valve tube 120 are equipped with rounded corner structures at both ends of the valve core assemblies (first valve core assembly 120, second valve core assembly 220). This prevents the valve body from experiencing instantaneous high hydraulic pressure when the flow channel is opened, causing the pressure on the discs to exceed the rated force range. The rounded corner structures also act as pressure dividers. In this embodiment, each valve core assembly has five discs. Due to the principle of the mechanical iris design mechanism, the pressure is actually borne by the connecting rods of five transmission mechanisms. Furthermore, each valve body adopts a double valve core design, where the double valve cores and the internal valve core mechanism, along with the rounded edges, simultaneously share the high hydraulic pressure from the tubes, dispersing the water hammer effect and reducing the risk of mechanical damage and reduced service life caused by vertical hydraulic pressure.

[0131] This invention also provides a cooling system having the valve body device described above; or, the cooling system having the valve body device described above. The first valve body 100 and the second valve body 200 can be used in scenarios such as adding coolant. They do not require an electrically controlled valve, can achieve blind insertion and removal, avoid dripping or leakage, and have good reliability.

[0132] This embodiment also provides a method of using a valve body device, which includes a docking step and / or a disengagement step.

[0133] The docking steps include:

[0134] Align the first valve body 100 with the second valve body 200 and insert it into the direction of the second valve tube 210;

[0135] The first valve body 100 drives the valve disc 230 of the second valve core assembly 220 to move, thereby opening the second valve body 200 (second flow channel 201);

[0136] The disengagement step includes:

[0137] Pulling the first valve body 100 away from the second valve body 200 resets the valve disc 230 of the second valve core assembly 220, and closes the second valve body 200 (second flow channel 201).

[0138] Specifically, when the first valve body 100 has a first valve core assembly 120, the docking step includes:

[0139] Align the first valve body 100 with the second valve body 200 and insert it into the direction of the second valve tube 210;

[0140] The valve disc 130 of the first valve core assembly 120 at the front end of the first valve body 100 is connected to the valve disc 230 of the second valve core assembly 220 at the front end of the second valve body 200.

[0141] The first valve body 100 drives the actuating component 250 inside the second valve body 200, causing the actuating component 250 to drive the valve disc 230 of the second valve core assembly 220 to rotate in the second direction, thereby opening the second valve body 200 (second flow channel 201).

[0142] When the valve disc 230 of the second valve core assembly 220 rotates in the second direction, it drives the valve disc 130 of the first valve core assembly 120 to rotate synchronously, thereby opening the first flow channel 101.

[0143] The disengagement step includes: pulling the first valve body 100 away from the second valve body 200, resetting the actuating member 250, causing the actuating member 250 to drive the valve disc 230 of the second valve core assembly 220 to rotate in the first direction, thereby closing the second flow channel 201.

[0144] When the valve disc 230 of the second valve core assembly 220 rotates in the first direction, it drives the valve disc 130 of the first valve core assembly 120 to rotate synchronously, thereby closing the first flow channel 101.

[0145] The valve disc 130 of the first valve core assembly 120 at the front end of the first valve body 100 is separated from the valve disc 230 of the second valve core assembly 220 at the front end of the second valve body 200.

[0146] When the first valve body 100 and the second valve body 200 are not connected, both the first valve core assembly 120 and the second valve core assembly 220 are in the closed state, and neither the first valve body 100 nor the second valve body 200 is conductive, thus preventing leakage. When the first valve body 100 and the second valve body 200 are connected, the insertion of the first valve body 100 drives the actuating member 250, causing the actuating member 250 to actuate and open the valve disc 230 of the second valve core assembly 220, thus enabling the second valve body 200 to conduct. Moreover, at the same time as the valve disc 230 of the second valve core assembly 220 actuates, the valve disc 230 of the second valve core assembly 220 simultaneously drives the valve disc 130 of the first valve core assembly 120 to open, thus enabling the first valve body 100 to conduct simultaneously. During the process of separating the first valve body 100 from the second valve body 200, i.e., during the process of pulling out the pipeline, the first valve body 100 releases the drive of the actuating member 250, and the actuating member 250 reverses its action. This causes the actuating member 250 to drive the valve disc 230 of the second valve core assembly 220 to reverse its action and switch from the conducting state to the closed state. Moreover, at the same time as the valve disc 230 of the second valve core assembly 220 reverses its action, the valve disc 230 of the second valve core assembly 220 drives the valve disc 130 of the first valve core assembly 120 to switch from the conducting state to the closed state simultaneously, so that the first valve body 100 closes at the same time. This can effectively prevent the first valve body 100 and the second valve body 200 from dripping or leaking liquid when docking, when separating, and after separation, and has good reliability.

[0147] Specifically, when the first valve body 100 drives the actuating member 250 in the second valve body 200, the actuating member 250 is pushed by the first valve body 100 and slides backward along the axial direction of the second valve tube 210. At the same time, the sliding member rotates in the second direction under the action of the sliding drive structure, thereby driving the valve disc 230 of each second valve core assembly 220 to rotate in the second direction.

[0148] When the first valve body 100 moves away from the second valve body 200 and releases the pressure on the actuating member 250, the actuating member 250 slides forward and resets along the axial direction of the second valve tube 210 under the action of the elastic member 282.
