Description

Technical Field

[0001] This utility model belongs to the field of valve-related technology, and in particular relates to a split-type one-way valve built into the hose of a centrifugal heat dissipation device. Background Technology

[0002] In centrifugal cooling systems such as engine cooling systems, coolant is often circulated via hoses. To prevent coolant backflow when centrifugal force decreases or the pump stops working, a check valve is usually installed in the pipeline to ensure unidirectional fluid flow, guaranteeing cooling efficiency and operational reliability. However, existing check valves have several significant technical drawbacks when applied to such scenarios with built-in hoses. Existing one-way valve structures, when installed in space-constrained scenarios such as inside hoses, often have limited valve disc opening areas, resulting in high resistance and limited flow rate. Furthermore, after being opened by fluid impact, existing valve discs may fail to quickly and accurately reset and close when fluid force dissipates due to insensitive or poorly designed reset mechanisms. This can easily lead to poor sealing and backflow, reducing heat dissipation efficiency and potentially adversely affecting the centrifugal cooling device itself. To address these issues, a double-opening one-way valve integrated into the hose of the centrifugal cooling device is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a centrifugal cooling device with a built-in split-type one-way valve in the hose. By using two sets of valve plates and the central shaft in a split-type structure, the flow rate can be increased and the flow resistance reduced in a limited space. At the same time, through the cooperation of the torsion spring and the valve plates, the valve plates can have an automatic reset function, thereby realizing automatic sealing of the cylinder.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a centrifugal heat dissipation device with a built-in split-type one-way valve in the hose, including a cylinder; inside the cylinder are two sets of valve plates that abut each other and are arranged in a circular shape, and a central shaft is provided at the position where the two sets of valve plates meet. Rotating ring plates are fixed on the side walls of the two sets of valve plates corresponding to the upper and lower parts of the central shaft, and each rotating ring plate is sleeved on the central shaft. Two sets of torsion springs arranged vertically are sleeved at the middle position of the central shaft.

[0005] The present invention is further configured such that the left end of the inner side of the cylinder is provided as a flow inlet, the right end of the inner side of the cylinder is provided as a flow outlet, and the diameter of the flow outlet is larger than the diameter of the flow inlet, and two sets of valve plates are provided at the position of the flow outlet.

[0006] The present invention is further configured such that a flow ring is provided on the inner end face of the flow outlet near the flow inlet, and a sealing ring is provided on the axial end face of the flow ring away from the valve plate, and the sealing ring abuts against the stepped surface inside the flow outlet to form a seal.

[0007] The present invention is further configured such that the interior of the flow outlet is configured with a threaded groove structure, and an outer screw is screwed into the interior of the flow outlet, and the outer screw abuts the flow ring, and the upper and lower ends of the central shaft are fixed on the inner wall of the outer screw.

[0008] The present invention is further configured such that two sets of valve plates are located in the outer screw cylinder and are in contact with the end face of the flow ring; the cylinder body is inserted into the outer rubber tube, and the protrusion of the outer wall of the cylinder body abuts against the inner wall of the rubber tube.

[0009] The present invention is further configured such that locking cylinders are screwed onto the threaded sections at the upper and lower ends of the central shaft inside the outer screw cylinder, and multiple rotating plates are positioned between the two sets of locking cylinders.

[0010] The present invention is further configured such that each valve plate has two sets of positioning strips fixed on the end face away from the flow ring, and one end of each set of torsion springs in the upper and lower positions is respectively located between two adjacent positioning strips.

[0011] This utility model has the following beneficial effects: The valve plate is installed in the outer screw barrel, and the outer screw barrel is installed in the cylinder body. The cylinder body is directly inserted into the inside of the hose. Since the two sets of valve plates adopt a split structure with the central shaft, when the valve plate is impacted, the two sets of valve plates will rotate synchronously, thereby increasing the flow rate and reducing the flow resistance in a limited space.

[0012] The valve plate is pushed by the torsion spring, and after being impacted by the fluid flow, the valve plate can automatically reset due to the reaction force of the torsion spring, thereby automatically sealing the cylinder. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0023] Please see Figures 1 to 7 This utility model is a centrifugal heat dissipation device with a built-in split-type one-way valve in the hose, including a cylinder 1; the inside of the cylinder 1 is provided with two sets of valve plates 2 that abut against each other and are arranged in a circular shape. A central shaft 3 is provided at the position where the two sets of valve plates 2 meet. Rotating ring plates 201 are fixed on the side walls of the two sets of valve plates 2 corresponding to the upper and lower parts of the central shaft 3, and each rotating ring plate 201 is sleeved on the central shaft 3. Two sets of torsion springs 4 are sleeved at the middle position of the central shaft 3 and arranged vertically. The valve plates 2 are pushed by the torsion springs 4, so that the valve plates 2 are impacted by the fluid flow. After the reaction force of the torsion springs 4, the valve plates 2 can have the function of automatic reset, thereby realizing the function of one-way flow. It should be noted that the entire device has a compact structure and can be installed inside a 45mm inner diameter tubing. No external installation structure is required; it can be used simply by inserting it into the tubing.

[0024] Specifically, the left end of the inner cavity of the cylinder 1 is provided with a flow inlet 105, and the right end of the inner cavity of the cylinder 1 is provided with a flow outlet 101. The diameter of the flow outlet 101 is larger than the diameter of the flow inlet 105. Two sets of valve plates 2 are located at the flow outlet 101. A flow ring 103 is provided at the inner end face of the flow outlet 101 near the flow inlet 105. A sealing ring 104 is provided at the axial end face of the flow ring 103 away from the valve plate 2. The sealing ring 104 abuts against the stepped surface inside the flow outlet 101 to form a seal. The sealing ring 104 is located between the end face of the flow ring 103 and the end face of the flow outlet 101. Therefore, the sealing ring 104 seals the gap between the end face of the flow ring 103 and the end face of the flow outlet 101, so that the fluid can only be discharged from the inner side of the flow ring 103. This allows the fluid to accurately impact the valve plate 2.

[0025] The flow outlet 101 has a threaded groove structure 106 inside, and an outer screw 102 is screwed into the flow outlet 101. The outer screw 102 abuts against the flow ring 103. Two sets of valve plates 2 are located in the outer screw 102 and are in contact with the end face of the flow ring 103. The upper and lower ends of the central shaft 3 are fixed to the inner wall of the outer screw 102. The outer screw 102 is screwed into the threaded groove structure 106, so that the outer screw 102 can be installed in the position of the flow outlet 101, and the two sets of valve plates 2 can be located in the flow outlet 101. At the same time, the outer screw 102 abuts against the flow ring 103, thereby ensuring that the flow ring 103 is stably installed in the flow outlet 101 position inside the cylinder 1 and that the flow ring 103 will not be displaced. The cylinder 1 is inserted into the external rubber tube, and the protrusion of the outer wall of the cylinder 1 abuts against the inner wall of the rubber tube.

[0026] Furthermore, locking cylinders 301 are screwed onto the threaded sections at the upper and lower ends of the central shaft 3 inside the outer screw cylinder 102. Multiple rotating plates 201 are positioned between the two sets of locking cylinders 301. The locking cylinders 301 are screwed onto the threaded sections at the ends of the central shaft 3, so that the locking cylinders 301 abut against the end faces of the rotating plates 201. This ensures that the rotating plates 201 will not sway up and down on the surface of the central shaft 3, and also ensures that the position of the valve plate 2 is stable.

[0027] Furthermore, each valve plate 2 has two sets of vertically arranged positioning strips 202 fixed on the end face away from the flow ring 103. The extensions of one end of the two sets of torsion springs 4 at the vertical position are respectively located between the two adjacent positioning strips 202. Since the extension of one end of the torsion spring 4 is located between the two sets of positioning strips 202, the positioning strips 202 play a role in limiting the torsion spring 4 and controlling the torsion spring 4 to prevent vertical displacement on the surface of the central shaft 3.

[0028] The operation process of this embodiment is as follows: First, the cylinder 1 is installed in the hose. Therefore, after the fluid of the centrifugal heat dissipation device flows into the inside of the hose, it will impact the two sets of valve plates 2, causing the two sets of valve plates 2 to rotate open and close about the central axis 3. At this time, the two sets of valve plates 2 will compress the torsion spring 4, and as the two sets of valve plates 2 rotate, the flow area opened will become larger and larger until the valve plates 2 are opened to the maximum extent. At this time, the fluid will continue to flow. When the fluid in the centrifugal heat dissipation device stops flowing, the two sets of valve plates 2 are pushed by the torsion spring 4 to return to the initial position, thereby closing the cylinder 1 and achieving a seal, so that the fluid will not flow back into the centrifugal heat dissipation device. At the same time, when the valve plate 2 is closed, its edge should be tightly fitted with the inner end face of the flow ring 103 (i.e. the side close to the valve plate) to form a seal.
