Description

Technical Field

[0001] This utility model relates to the field of valve body technology, and in particular to an open-type check valve structure. Background Technology

[0002] In modern electronic equipment, new energy vehicle power battery packs, and industrial precision machinery, liquid cooling systems, with their high-efficiency heat dissipation performance, are a core guarantee for maintaining stable equipment operation. In these complex heat dissipation systems, the coolant acts like blood in the human body, carrying away the large amount of heat generated during equipment operation through circulation. Its stable circulation is key to achieving efficient heat dissipation. When the system is under normal operation, the coolant flows orderly in a precisely designed piping network, working in conjunction with components such as heat exchangers and water pumps to quickly transfer the heat generated by the equipment to the external environment, ensuring that the equipment always remains within a suitable operating temperature range.

[0003] However, when a liquid cooling system faces shutdown, maintenance, or abnormal operating conditions, the balance of the entire system is disrupted, leading to potential risks. Without reliable protective measures, coolant may flow from higher to lower levels due to gravity, or leak through connections or weak points in the system due to pressure differences. Simultaneously, outside air can quickly enter and fill the space left by the outflowing coolant. This airflow creates airlocks in the pipes, severely hindering the normal flow of coolant, causing a sharp drop in heat dissipation efficiency, a rapid rise in equipment temperature, and potentially triggering overheat protection shutdowns, affecting normal equipment operation. Furthermore, moisture and oxygen in the air can react chemically with the coolant and metal pipes, accelerating corrosion, shortening the system's lifespan, increasing maintenance costs, and raising the risk of sudden failures.

[0004] Therefore, this utility model proposes an exposed backflow prevention structure as a core component to prevent coolant leakage and block air from entering, thereby ensuring the reliability and safety of the liquid cooling system. Utility Model Content

[0005] The purpose of this utility model is to solve the defects existing in the prior art and to propose an open-type anti-reverse structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An open-type check valve structure includes a valve body, a valve core, and a valve seat arranged sequentially. The valve body has a valve body groove that is adapted to the valve core. The valve core includes an integrally formed or fixedly connected hinge shaft and a baffle. The hinge shaft is rotatably connected within the valve body groove. The diameter of the baffle is larger than the channel diameter of the valve body, and the channel diameter of the valve seat is larger than the diameter of the baffle. The valve body groove is located between the channel of the valve body and the channel of the valve seat.

[0008] Furthermore, a connection port is provided on the side of the valve body away from the valve seat, and a first sealing ring is provided at the connection port. The connection port is used to connect with the water distributor.

[0009] Furthermore, the valve body groove includes a cylindrical groove and a circular groove, the cylindrical groove and the circular groove are integrally formed, the cylindrical groove is adapted to the hinge shaft, and the circular groove is adapted to the baffle.

[0010] Furthermore, the valve body and valve seat are detachably connected, and a second sealing ring is provided on the side of the valve body adjacent to the valve seat.

[0011] Furthermore, the valve core has a threaded hole on its end face near the valve body, a screw is provided in the threaded hole, and a rubber gasket is provided between the screw and the valve core. The diameter of the rubber gasket is adapted to the diameter of the baffle.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the liquid cooling system is operating normally, the coolant pushes the valve core under pressure. The valve core itself is lightweight enough to ensure that the liquid pushes it open, so that the valve core and valve seat form a certain angle, the passage is opened, and the coolant passes smoothly through the valve body. When a leak occurs, the system itself will generate negative pressure. Under the suction of the negative pressure, the valve core and valve body are tightly fitted together. The negative pressure generates compression, making the valve core and valve body stick together tightly, closing the passage, preventing coolant leakage and outside air from entering the system, thus achieving the check valve function.

The valve body 2 has a valve body groove that is adapted to the valve core 6. The valve core 6 includes an integrally formed or fixedly connected hinge shaft and a baffle. The hinge shaft is rotatably connected in the valve body groove. The diameter of the baffle is larger than the channel diameter of the valve body 2, and the channel diameter of the valve seat 7 is larger than the diameter of the baffle.

[0021] When the liquid cooling system is operating normally, the coolant pushes the valve core 6 under pressure. The valve core 6 itself is lightweight enough to ensure that the liquid pushes the valve core 6 open, so that the valve core 6 and the valve seat 7 form a certain angle, the passage is opened, and the coolant passes smoothly through the valve body 2. When leakage occurs, the system itself will generate negative pressure. Under the suction of the negative pressure, the valve core 6 and the valve body 2 are tightly fitted together. The negative pressure generates compression, making the valve core 6 and the valve body 2 stick together tightly, the passage is closed, and the coolant leakage and outside air entering the system are prevented, thereby realizing the non-reverse function.

[0022] Among them, the valve body 2 is the main frame of the open-air check structure.

The connection port is used to connect with the water distributor. The function of the first sealing ring is to ensure the sealing effect at the connection position between the valve body 2 and the water distributor.

[0024] In other preferred embodiments, the valve body groove includes a cylindrical groove and a circular groove, which are integrally formed. The cylindrical groove is adapted to the hinge shaft, and the circular groove is adapted to the baffle. The valve core 6 is pressed down by the valve seat 7 and can only move around the axis to control the opening and closing of the valve core 6.

[0025] In other preferred embodiments, the valve body 2 and the valve seat 7 are detachably connected, and a second sealing ring 3 is provided on the side of the valve body 2 adjacent to the valve seat 7. The function of the second sealing ring is to ensure the sealing effect at the connection position between the valve body 2 and the valve seat 7.

[0026] In other preferred embodiments, the valve core 6 has a threaded hole on its end face near the valve body 2, and a screw 4 is installed in the threaded hole. A rubber gasket 5 is placed between the screw 4 and the valve core 6, and the diameter of the rubber gasket is adapted to the diameter of the baffle. The sealing gasket is locked onto the valve core 6 by the screw 4. The sealing components are mostly made of elastic materials such as rubber and EPDM to ensure the sealing effect.
