[0054] Specifically, when the first valve body terminal drives the actuating component inside the second valve body terminal, the actuating component is pushed by the first valve body terminal and slides away from the second valve tube along the axial direction of the second valve tube.

[0055] The present invention provides a valve body terminal, a valve body, a cooling system, and a method of using the valve body. When the second valve body terminal is connected to the first valve body terminal, the actuating component drives the second valve disc to make the second valve body terminal conductive. At the same time, the second valve disc can drive the first valve disc of the first valve body terminal to make the first valve body terminal conductive. This can effectively prevent the first valve body terminal and the second valve body terminal from dripping or leaking outwards when connected, disconnected, and after disconnection. Moreover, the valve body opens and closes quickly and has good reliability. Attached Figure Description

[0075] 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.

[0076] 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.

[0077] 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.

[0078] Example 1:

[0079] like Figures 1 to 7 As shown, an embodiment of the present invention provides a valve body terminal, including a first valve body terminal 100, wherein the first valve body terminal 100 includes a first valve tube 110, a first valve core assembly 120 and a first guide plate 140;

[0080] The first valve core assembly 120 is disposed inside the first valve tube 110, or the first valve core assembly 120 at least partially protrudes from the first valve tube 110. The first valve core assembly 120 includes at least two first valve discs 130. The first guide plate 140 is provided with a first guide rail 143. Each of the first valve discs 130 moves closer to or further away from each other along the first guide rail 143 to close or open the first valve tube 110. Its structure has high reliability, and the closure or opening of the first valve tube 110 can be made faster and more reliable by simultaneously driving each of the first valve discs 130.

[0081] Specifically, the first guide plate 140 can be disposed inside the first valve tube 110 or outside the first valve tube 110.

[0082] In practical applications, the first valve disc 130 can move in various ways. Multiple first valve discs 130 may move simultaneously to open or close the first valve tube 110, or one (partial) of the first valve discs 130 may remain stationary while another (partial) of the first valve discs 130 moves to open or close the first valve tube 110. The first 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.

[0083] Specifically, when the plurality of first valve discs 130 approach each other along the first guide rail 143, the first valve tube 110 is closed; when the plurality of first valve discs 130 move away from each other along the first guide rail 143, the first valve tube 110 is opened.

[0084] Specifically, there may be one first valve core assembly 120; or, there may be at least two first valve core assemblies 120, each first valve core assembly 120 being arranged along the axial direction of the first valve tube 110, and the first valve disc 130 of each first valve core assembly 120 operating synchronously.

[0085] In this embodiment, two first valve core assemblies 120 are provided, namely a front first valve core assembly 120a and a rear first valve core assembly 120b, with the front first valve core assembly 120a being relatively close to the front end of the first valve body terminal 100. A synchronizing rod connects the first valve disc 130 of the front first valve core assembly 120a and the first valve disc 130 of the rear first valve core assembly 120b. A first water chamber is formed between the two first valve core assemblies 120, and the two first valve core assemblies 120 open and close synchronously, which helps to avoid leakage during the insertion and removal process. The synchronizing rod is used to synchronize the operation of the first valve disc 130 of the front first valve core assembly 120a and the first valve disc 130 of the rear first valve core assembly 120b.

[0086] Specifically, the first guide plate 140 of the front first valve core assembly 120a and the first guide plate 140 of the rear first valve core assembly 120b are disposed in contact with each other; the front first valve core assembly 120a and the rear first valve core assembly 120b can adopt the same configuration as the second valve core assembly 220.

[0087] Alternatively, the first guide plate 140 of the front first valve core assembly 120a and the first guide plate 140 of the rear first valve core assembly 120b are integrally formed as a common guide plate, and the first valve flap 130 of the front first valve core assembly 120a and the first valve flap 130 of the rear first valve core assembly 120b are respectively connected to the two sides of the common guide plate, which has a simple and reliable structure.

[0088] Specifically, the first guide plate 140 can be disposed inside the first valve pipe 110.

[0089] Specifically, such as Figure 18 As shown, the first valve disc 130 has a trapezoidal structure for multi-faceted contact with adjacent first valve discs 130, and the adjacent first valve discs 130 are partially overlapped, resulting in a good sealing effect.

[0090] Specifically, the first valve disc 130 includes a first layer disc portion 310 and a second layer disc portion 320 arranged in layers. The second layer disc portion 320 is provided with a rotating connecting shaft. The first layer disc portion 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 disc portion 320, which has a good sealing effect and good resistance to liquid impact.

[0091] 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 can be a rubber layer, which can further improve the reliability of the seal.

[0092] Example 2:

[0093] This invention also provides a valve body terminal that can be plugged into and used with the valve body terminal (i.e., the first valve body terminal 100) in Embodiment 1. The valve body terminal in this embodiment includes a second valve body terminal 200, which includes a second valve tube 210, a second valve core assembly 220, a second guide plate 240, and an actuating member 250.

[0094] 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 250 is disposed within the second valve tube 210, and the second guide disk 240 and the actuating member 250 are disposed within the second valve tube 210. The second valve core assembly 220 includes at least two second valve discs 230, and the second guide disk 240 is provided with a second guide rail 244. The actuating member 250 drives the plurality of second valve discs 230 to move closer or further away from each other along the second guide rail 244 to close or open the second valve tube. Its structure has high reliability, and the closing or opening of the second valve tube 210 can be made faster and more reliable by simultaneously driving each second valve disc 230. The second guide disk 240 can be disposed within or outside the second valve tube 210.

[0095] Specifically, such as Figures 8 to 13 As shown, 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 actuating member rotates by the sliding drive structure. That is, by utilizing the insertion driving force of the first valve body terminal 100 being inserted into the second valve body terminal 200 during docking, the actuating member rotates circumferentially while sliding axially. No electrical control is required, making the application more convenient.

[0096] Specifically, such as Figures 8 to 14 As shown, the actuating component 250 includes a movable disk, and the sliding drive structure includes an actuating 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 pipe 210. The actuating guide portion 251 extends into the guide groove 211. In this way, the linear sliding of the actuating component 250 can be converted into linear sliding and circumferential rotation, thereby causing the actuating component 250 to drive the second valve disc 230 to rotate synchronously through rotation, and the second valve disc 230 drives the first valve disc 130 to rotate synchronously.

[0097] 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.

[0098] Specifically, such as Figures 8 to 14As shown, at least two actuation guides 251 are provided, each actuation guide 251 being evenly distributed along the outer circumference of the movable disc; at least two sets of guide grooves 211 are provided, and the number of guide grooves 211 is equal to the number of actuation guides 251, each guide groove 211 being evenly distributed along the inner circumference of the second valve pipe 210. In this embodiment, two actuation guides 251 are symmetrically arranged, and two sets of guide grooves 211 are symmetrically arranged.

[0099] Specifically, such as Figures 8 to 14 As shown, the actuation 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 actuation component 250 smoother.

[0100] 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 terminal 100 and the second valve body terminal 200 are connected, the first valve body terminal 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 second valve disc 230 to rotate relative to the second guide plate 240.

[0101] 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.

[0102] 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 second valve disc 230 to rotate synchronously through the transmission structure, so that the second valve body terminal 200 can be turned on and off.

[0103] 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 terminal 100 and the second valve body terminal 200 are connected, the second valve disc 230 and the first valve disc 130 are connected through the linkage structure and move synchronously, so that the first valve body terminal 100 and the second valve body terminal 200 can be turned on and off at the same time.

[0104] Specifically, such as Figures 1 to 17 As shown, each second valve disc 230 is connected to the second guide disk 240 via a rotating shaft 231. The transmission structure includes a transmission rod 261 for driving the second valve disc 230 to swing around the rotating shaft 231. The second valve disc 230 adopts a mechanical iris configuration, which can effectively seal the second valve hole 241. Each second valve disc 230 is connected to a transmission rod 261, and each transmission rod 261 is connected to an actuating member 250, which allows each second valve disc 230 to swing synchronously around the rotating shaft 231 to seal or open the second valve hole 241. The first valve disc 130 can adopt the same or similar structure as the second valve disc 230. In specific applications, the first valve disc 130 and the second valve disc 230 can be the same (generally applicable), and the first valve core assembly 120 and the second valve core assembly 220 can be the same (generally applicable).

[0105] 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 second valve disc 230, 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 terminal 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.

[0106] 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 first direction through the drive groove 253, causing the second valve disc 230 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 second direction through the drive groove 253, causing the second valve disc 230 to rotate in the direction of opening the second valve hole 241.

[0107] Specifically, such as Figure 15 , Figure 16 As 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 terminal 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.

[0108] Specifically, when there are two or more first valve core assemblies 120, the first 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 first valve disc 130 at the front end of the first valve body terminal 100 is the first linkage valve core.

[0109] Specifically, when there are two or more second valve core assemblies 220, the second valve discs 230 of each second valve core assembly 220 can be connected by a transmission rod, so that each second valve core assembly 220 can 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 second 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 through transmission rods. The second valve disc 230 at the front end of the second valve body terminal 200 is the second linkage valve core. The linkage structure is set between the first linkage valve core and the second linkage valve core. When the first valve body terminal 100 and the second valve body terminal 200 are connected, the first linkage valve core and the second linkage valve core face each other and are connected through the linkage structure, so that each second valve core assembly 220 can open or close synchronously. The linkage structure can adopt a plug-in mating structure.

[0110] Specifically, the linkage structure includes an insertion hole 171 disposed in each first linkage valve core (first valve disc 130) and a linkage insertion shaft 271 disposed in each second linkage valve core (second valve disc 230) and insertable into the insertion hole 171; or, the linkage structure includes an insertion hole 171 disposed in each second linkage valve core (second valve disc 230) and a linkage insertion shaft 271 disposed in each first linkage valve core (first valve disc 130) and insertable into the insertion hole 171. In this embodiment, each first linkage valve core is provided with an insertion hole 171, and each second linkage valve core 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 terminal 100 and the second valve body terminal 200 are connected, 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 terminal 100 can be linked with the second valve core assembly 220 of the second valve body terminal 200.

[0111] Specifically, the second valve body terminal 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 terminal 100 is pulled out of the second valve body terminal 200, the second valve core assembly 220 and the actuating member 250 can be reset in time.

[0112] 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.

[0113] Specifically, a sealing ring 283 is fitted around the outer periphery of the first inner tube 288 to prevent leakage and improve the sealing effect.

[0114] Specifically, there may be one second valve core assembly 220; or, there may be at least two second valve core assemblies 220, each second valve core assembly 220 being arranged along the axial direction of the second valve tube 210, and the second valve disc 230 of each second valve core assembly 220 operating synchronously.

[0115] Specifically, there are two second valve core assemblies 220, namely a front second valve core assembly 220a and a rear second valve core assembly 220b. The front second valve core assembly 220a and the rear second valve core assembly 220b are respectively disposed on both sides of the actuating member 250, and the front second valve core assembly 220a is relatively close to the front end of the second valve body terminal 200. The second valve disc 230 of the front second valve core assembly 220a and the second valve disc 230 of the rear second valve core assembly 220b are respectively connected to the actuating member 250 through the transmission rod 261. A second water chamber is formed between the two second valve core assemblies 220. The two second valve core assemblies 220 (the front second valve core assembly 220a and the rear second valve core assembly 220b) open and close synchronously, which helps to avoid leakage during the insertion and removal process.

[0116] The second valve disc 230 can have the same structure as the first valve disc 130 in Embodiment 1. Specifically, the second valve disc 230 has a trapezoidal structure for multi-faceted contact with adjacent second valve discs 230, and the adjacent second valve discs 230 are partially overlapped, resulting in a good sealing effect.

[0117] In practical applications, the second valve disc 230 can move in various ways. Multiple second valve discs 230 may move simultaneously to open or close the second valve tube 210. Alternatively, one (partial) of the second valve discs 230 may remain stationary while another (partial) of the second valve discs 230 moves to open or close the second valve tube 210. The second 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.

[0118] Specifically, the second valve disc 230 includes a first layer disc portion 310 and a second layer disc portion 320 arranged in layers. The second layer disc portion 320 is provided with a rotating connecting shaft. The first layer disc portion 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 disc portion 320, which has a good sealing effect and good resistance to liquid impact.

[0119] 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 can be a rubber layer, which can further improve the reliability of the seal.

[0120] Example 3:

[0121] like Figures 1 to 18 As shown, the present invention also provides a valve body, including a valve body terminal (first valve body terminal 100) as described in Embodiment 1, and a valve body terminal (second valve body terminal 200) as described in Embodiment 2.

[0122] Specifically, the first valve core assembly 120 at least partially protrudes from the first valve tube 110, and the second valve core assembly 220 is located within the second valve tube 210; or the first valve core assembly 120 is located within the first valve tube 110, and the second valve core assembly 220 at least partially protrudes from the second valve tube 210.

[0123] In this embodiment, the valve body has a second valve disc that is linked to the first valve disc through a linkage structure, so that the first valve tube and the second valve tube can be closed or opened synchronously.

[0124] like Figures 1 to 18As shown, there is a first valve body terminal 100 and a second valve body terminal 200. When the first valve body terminal 100 and the second valve body terminal 200 are connected, fluid can flow through the first valve body terminal 100 and the second valve body terminal 200. The first valve body terminal 100 has a first flow channel 101. The first valve body terminal 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 first valve disc 130. The first valve disc 130 can be driven by the second valve body terminal 200 when it is connected to the first valve body terminal 100 to open the first flow channel 101. That is, the first valve disc 130 is driven to open the first flow channel 101 by the connection of the first valve body terminal 100 and the second valve body terminal 200.

[0125] like Figures 8 to 10 As shown, the second valve body terminal 200 has a second flow channel 201. The second valve body terminal 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 tube 210 and driven by the first valve body terminal 100. The second valve core assembly 220 also includes a second valve disc 230 driven by the actuating member 250 to open the second flow channel 201. When the second valve body terminal 200 is connected to the first valve body terminal 100, the second valve disc 230 can drive the first valve disc 130 of the first valve body terminal 100. When the first valve body terminal 100 is connected to the second valve body terminal 200, the first valve disc 130 is driven by the second valve disc 230 of the second valve body terminal 200. Thus, when the first valve body terminal 100 and the second valve body terminal 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 terminal 100 nor the second valve body terminal 200 is conductive, preventing leakage. Figures 11 to 13As shown, when the first valve body terminal 100 is connected to the second valve body terminal 200, the insertion of the first valve body terminal 100 drives the actuating member 250, causing the actuating member 250 to drive the second valve disc 230 to open, thus making the second valve body terminal 200 conductive. Moreover, at the same time as the second valve disc 230 is activated, the second valve disc 230 drives the first valve disc 130 to open synchronously, thus making the first valve body terminal 100 conductive at the same time. During the process of disconnecting the first valve body terminal 100 from the second valve body terminal 200, i.e., during the process of pulling out the pipeline, the first valve body terminal 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 second valve disc 230 to reverse its action and switch from the conducting state to the closed state. Moreover, at the same time as the second valve disc 230 reverses its action, the second valve disc 230 drives the first valve disc 130 to switch from the conducting state to the closed state simultaneously, so that the first valve body terminal 100 closes at the same time. This can effectively prevent the first valve body terminal 100 and the second valve body terminal 200 from dripping or leaking outwards during docking, disconnection, and after disconnection, resulting in high reliability.

[0126] Specifically, when the first valve core assembly 120 and the second valve core assembly 220 are synchronized, the first valve tube 110 and the second valve tube 210 are sealed together.

[0127] Specifically, such as Figures 1 to 7 As shown, the first valve core assembly 120 also includes a first guide disk 140. The first guide disk 140 can be assembled inside the first valve tube 110, or the first guide disk 140 can be integrally formed inside the first valve tube 110. In this embodiment, the outer periphery of the first guide disk 140 is in contact with the inner wall of the first valve tube 110. The first guide disk 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 terminal 100. At least two first valve discs 130 are provided and are rotatably or slidably connected to the first guide disk 140. The first valve discs 130 can rotate or slide to a closed state to block the first valve hole 141. By controlling the first valve discs 130 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 first valve discs 130 are rotatably connected to the first guide disk 140.

[0128] Specifically, a first sealing gasket 142 may be provided between the first guide plate 140 and the first valve disc 130 to ensure sealing.

[0129] Specifically, such as Figures 8 to 13As 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 terminal 100. At least two second valve discs 230 are provided and are rotatably or slidably connected to the second guide disk 240. The second valve discs 230 can rotate or slide to a closed state to block the second valve hole 241. By controlling the second valve discs 230 to rotate (or slide) to a closed state, the second valve hole 241 can be opened or closed. In this embodiment, the second valve discs 230 are rotatably connected to the second guide disk 240.

[0130] Specifically, a second sealing gasket 242 can be provided between the second guide plate 240 and the second valve disc 230 to ensure sealing.

[0131] 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.

[0132] In this embodiment, each first valve core assembly 120 and each second valve core assembly 220 includes five discs (first valve disc 130 and second valve disc 230), and the maximum rotation angle of the discs can be 52 degrees. Of course, in specific applications, the number of discs and the maximum rotation angle can also be set according to the actual situation.

[0133] 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.

[0134] 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.

[0135] This invention also provides a cooling system having the first valve body terminal 100 or the second valve body terminal 200 described above; or, the cooling system having one of the valve body terminals described above. The first valve body terminal 100 and the second valve body terminal 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.

[0136] This embodiment also provides a method of using a valve body, which includes a docking step and / or a disengagement step.

[0137] The docking steps include:

[0138] Align the first valve body terminal 100 with the second valve body terminal 200 and insert it in the direction of the second valve body terminal 200;

[0139] The first valve disc 130 at the front end of the first valve body terminal 100 and the second valve disc 230 at the front end of the second valve body terminal 200 are connected through a linkage structure.

[0140] The first valve body terminal 100 drives the actuating member 250 in the second valve body terminal 200, causing the actuating member 250 to drive the second valve disc 230 to rotate in the first direction, thereby turning on the second valve body terminal 200.

[0141] When the second valve disc 230 rotates in the first direction, it drives the first valve disc 130 to rotate synchronously, thereby making the first valve body terminal 100 conductive.

[0142] The disengagement step includes: pulling the first valve body terminal 100 away from the second valve body terminal 200, resetting the actuating member 250, causing the actuating member 250 to drive the second valve disc 230 to rotate in the second direction, thereby closing the second valve body terminal 200.

[0143] When the second valve disc 230 rotates in the second direction, it drives the first valve disc 130 to rotate synchronously, thereby closing the first valve body terminal 100.

[0144] The first valve disc 130 at the front end of the first valve body terminal 100 separates from the second valve disc 230 at the front end of the second valve body terminal 200.

[0145] When the first valve body terminal 100 and the second valve body terminal 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 terminal 100 nor the second valve body terminal 200 is conductive, thus preventing leakage. When the first valve body terminal 100 and the second valve body terminal 200 are connected, the insertion of the first valve body terminal 100 drives the actuating member 250, causing the actuating member 250 to move and open the second valve disc 230, thus making the second valve body terminal 200 conductive. Moreover, at the same time as the second valve disc 230 moves, the second valve disc 230 drives the first valve disc 130 to open synchronously, thus making the first valve body terminal 100 conductive at the same time. During the process of disconnecting the first valve body terminal 100 from the second valve body terminal 200, i.e., during the process of pulling out the pipeline, the first valve body terminal 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 second valve disc 230 to reverse its action and switch from the conducting state to the closed state. Moreover, at the same time as the second valve disc 230 reverses its action, the second valve disc 230 drives the first valve disc 130 to switch from the conducting state to the closed state simultaneously, so that the first valve body terminal 100 closes at the same time. This can effectively prevent the first valve body terminal 100 and the second valve body terminal 200 from dripping or leaking outwards during docking, disconnection, and after disconnection, resulting in high reliability.

[0146] Specifically, when the first valve body terminal 100 drives the actuating member 250 in the second valve body terminal 200, the actuating member 250 is pushed by the first valve body terminal 100 and slides away from the second valve tube along the axial direction of the second valve tube 210. At the same time, the actuating member rotates along the first direction under the action of the sliding drive structure, thereby driving each second valve disc 230 to rotate in the first direction.

[0147] When the first valve body terminal 100 moves away from the second valve body terminal 200 and releases the pressure on the actuating member 250, the actuating member 250 slides and resets along the axial direction of the second valve tube 210 towards the direction away from the second valve tube under the action of the elastic member 282. At the same time, the actuating member rotates along the second direction under the action of the sliding drive structure, thereby driving each second valve disc 230 to rotate in the second direction.

[0148] The valve body terminal, valve body, cooling system, and method of using the valve body provided in this embodiment of the invention can effectively prevent the first valve body terminal 100 and the second valve body terminal 200 from dripping or leaking outwards when they are connected, disconnected, or disconnected. It can be used to transport refrigerant into the cooling system and meets the design requirements of being able to be plugged in and out at will while avoiding leakage, with good reliability.

[0149] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
