Description

Technical Field

[0001] This utility model belongs to the technical field of radiator sealing heads, and in particular relates to a sealing plug for aluminum-plastic radiators. Background Technology

[0002] The sealing plug of an aluminum-plastic radiator is an important component used to seal the radiator interface and prevent water leakage. It is usually made of high-temperature and corrosion-resistant materials, such as copper, stainless steel, or high-strength plastic. Its main functions include sealing unused inlets and outlets, regulating the system (such as venting or drainage), and withstanding the water pressure of the heating system. However, the sealing plug of an aluminum-plastic radiator still has the following drawbacks in actual use:

[0003] The sealing plug of the aluminum-plastic radiator is placed in the opening of the radiator. The sealing plug is directly screwed onto the corresponding radiator and sealed by the sealing ring on the inner top. After sealing, the sealing effect of the plug is often affected by factors such as deformation of the opening.

[0004] Secondly, during the sealing process of the sealing plug, the aluminum-plastic radiator is installed on it, and the radiator opening is kept sealed as the work progresses. However, after a long period of work, due to the pressure, the sealing plug will leak due to pressure, affecting the sealing effect of the sealing plug. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing plug for aluminum-plastic radiators. By setting up a shell, a fixing tube and a compression ring, it solves the problem that the sealing plug of aluminum-plastic radiators has insufficient sealing effect and is prone to leakage after long-term pressure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sealing plug for an aluminum-plastic radiator, comprising a shell, a fixing tube, and a clamping ring. A fixing ring is fixed to the upper inner part of the shell, and a flexible ring is embedded and fixed to the inner wall of the shell below the fixing ring. A fixing tube is provided inside the fixing ring, and an upper connecting plate is fixed to the bottom end of the fixing tube. An elastic ring is fixed to the bottom end of the upper connecting plate, and a lower connecting plate is fixed to the bottom end of the elastic ring. A clamping ring is fixed to the bottom end of the shell. In operation, the upper connecting plate, elastic ring, and lower connecting plate connected by the fixing tube are housed within the shell. After the shell is installed in a suitable position on the radiator, the clamping ring seals the connection between the clamping ring and the radiator.

[0008] Furthermore, a fixed sleeve is fixedly connected to the center of the top of the outer shell, and the fixed tube passes vertically through the top of the outer shell and is fixed inside the fixed sleeve. The fixed tube extends out of the top of the fixed sleeve, and the fixed sleeve is welded to the center of the top of the outer shell to fix the fixed tube passing through it. The upper end of the fixed tube extends out of the fixed sleeve to connect to the gas source, and the lower end extends into the interior of the outer shell to form a stable gas channel structure.

[0009] Furthermore, an air nozzle is fixedly connected to the top of the fixed tube, and a connecting cap is threadedly connected to the upper part of the circumference of the air nozzle. The air nozzle is welded to the top of the fixed tube, and the external threaded connecting cap can be screwed to seal the air nozzle. When inflating, the connecting cap is removed and connected to the air source interface. After inflation, the connecting cap is tightened to maintain a seal, thus realizing the function of repeated inflation and deflation.

[0010] Furthermore, a sealing ring is fixed to the bottom end of the fixing ring. The sealing ring is positioned above the flexible ring and fixed to the inner wall of the outer shell. An annular sealing ring is embedded at the bottom of the fixing ring, located directly above the flexible ring. When the outer shell is fitted onto the radiator, the sealing ring first contacts the radiator port to form a primary seal, while simultaneously limiting the downward pressure stroke of the outer shell.

[0011] Furthermore, the bottom end of the fixed tube is connected to the cavity formed by the upper connecting plate, the elastic ring and the lower connecting plate. The diameter of the upper connecting plate is larger than that of the lower connecting plate. The lower end of the fixed tube is connected to a sealed cavity formed by the upper and lower connecting plates and the elastic ring. The larger diameter of the upper connecting plate forms an expansion cavity. When inflated, the elastic ring expands radially, generating a downward squeezing force to make the radiator port fit tightly with the flexible ring.

[0012] Furthermore, the bottom of the outer casing is open, and a flexible inner ring is fixed to the inner ring of the clamping ring. The flexible inner ring is fixed to the bottom of the outer casing and is located outside the opening. A flexible contact ring is fixed to the bottom end of the clamping ring and the flexible inner ring. The bottom of the outer casing is an open structure. The clamping ring is connected to the outer casing through the flexible inner ring. During installation, the flexible contact ring is deformed by pressure and forms an annular sealing band with the outer wall of the radiator. This, together with the internal sealing structure, achieves double sealing protection.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of insufficient sealing effect of the sealing plug in aluminum-plastic radiators by setting up a shell and a clamping ring. After the shell is installed on the radiator opening, the clamping ring presses onto the radiator. After the flexible contact ring at the bottom of the clamping ring presses onto the radiator, the radiator and the clamping ring are pressed together, so that the gap between the shell and the radiator is initially sealed, increasing the sealing effect between the shell and the radiator. The sealing ring at the bottom of the fixing ring further cooperates to seal, and the sealing effect of the sealing plug of the aluminum-plastic radiator is increased through two-step sealing.

[0015] This invention solves the problem of leakage in the sealing plug of aluminum-plastic radiators after prolonged pressure by setting up an outer shell and a fixing tube. After sealing the radiator opening, the outer shell is rotated and fitted onto the outside of the opening until the opening presses against the sealing ring at the bottom of the fixing ring, creating a tight seal. The fixing ring then restricts the position. Next, the connecting cap on the air nozzle is rotated and unscrewed. An inflation connector is then installed on the air nozzle, allowing high-pressure air to be delivered to the fixing tube. This air then flows into the space between the upper connecting plate, the elastic ring, and the lower connecting plate, causing the elastic ring to inflate and expand, compressing the radiator opening. This ensures that the radiator opening is tightly sealed against the flexible ring, effectively sealing the gap between the radiator opening and the outer shell. This active pressure compression effectively prevents leakage in the sealing plug of the aluminum-plastic radiator after prolonged pressure. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to a sealing plug for an aluminum-plastic radiator, comprising a housing 1, a fixing pipe 2, and a clamping ring 3. A fixing ring 102 is fixed to the upper inner part of the housing 1. The housing 1 is fitted over the outer side of the radiator opening, sealing the opening. A flexible ring 104 is embedded and fixed on the inner wall of the housing 1 below the fixing ring 102. Threads are formed on the inner wall of the housing 1 below the flexible ring 104, connecting to the corresponding radiator opening. After the pipe at the radiator opening is fitted into the housing 1, it is pressed against the flexible ring 104 by the inner pressure. In the sealing operation, a fixing pipe 2 is provided on the inner side of the fixing ring 102. An upper connecting plate 201 is fixed to the bottom end of the fixing pipe 2. An elastic ring 202 is fixed to the bottom end of the upper connecting plate 201. A lower connecting plate 203 is fixed to the bottom end of the elastic ring 202. The fixing pipe 2 delivers high-pressure air between the upper connecting plate 201 and the lower connecting plate 203, squeezing and expanding the elastic ring 202, so that the opening end of the radiator is squeezed and tightened. A clamping ring 3 is fixed to the bottom end of the outer shell 1. The clamping ring 3 is pressed onto the radiator, further sealing the gap between the outer shell 1 and the radiator.

[0026] Specifically, a fixed sleeve 101 is fixedly connected to the center of the top of the outer shell 1. The fixed tube 2 passes vertically through the top of the outer shell 1 and is fixed inside the fixed sleeve 101. The fixed tube 2 extends out of the top of the fixed sleeve 101. When the outer shell 1 is working, the fixed tube 2 is fixed by the fixed sleeve 101.

[0027] Furthermore, an air nozzle 204 is fixedly connected to the top of the fixed tube 2, and a connecting cap 205 is threadedly connected to the upper part of the periphery of the air nozzle 204. The air nozzle 204 on the fixed tube 2 provides the function of inflation and deflation, and the air nozzle 204 is sealed after inflation by the connecting cap 205.

[0028] Furthermore, a sealing ring 103 is fixed to the bottom end of the fixing ring 102. The sealing ring 103 is positioned above the flexible ring 104 and is fixed to the inner wall of the outer shell 1. After the fixing ring 102 compresses the opening end of the radiator through the sealing ring 103, it seals the opening end of the radiator with the outer shell 1.

[0029] Furthermore, the bottom end of the fixed tube 2 is connected to the cavity formed by the upper connecting plate 201, the elastic ring 202 and the lower connecting plate 203. When inflated, the cavity expands, pushing the elastic ring 202 to deform radially to enhance the seal. The diameter of the upper connecting plate 201 is larger than the diameter of the lower connecting plate 203. The fixed tube 2 delivers the inflated air to the cavity formed by the upper connecting plate 201, the elastic ring 202 and the lower connecting plate 203.

[0030] The operation process of this embodiment is as follows: During operation, when it is necessary to close the opening of the radiator, rotate the outer shell 1 onto the outside of the opening on the radiator until the opening on the radiator presses against the sealing ring 103 at the bottom of the fixing ring 102, and the opening is tightly pressed against the sealing ring 103. The position is restricted by the fixing ring 102. Then, rotate the connecting cap 205 on the air nozzle 204. After unscrewing the connecting cap 205, install the air inflator on the air nozzle 204, and deliver high-pressure air to the fixing pipe 2. Then, deliver the air to the space formed between the upper connecting plate 201, the elastic ring 202 and the lower connecting plate 203, so that the elastic ring 202 is inflated and expands, squeezing the radiator opening. After the radiator opening is pressed against the flexible ring 104, the gap between the radiator opening and the outer shell 1 is fully sealed, and the radiator opening is blocked and sealed. When disassembling, release the air through the air nozzle 204, so that the elastic ring 202 is loosened from the radiator opening, and the outer shell 1 can be easily rotated off the radiator opening. Specific Implementation Example 2

[0031] Please see Figure 1 , 2 4. Based on the specific embodiment one, the bottom of the outer shell 1 is open. The inner ring of the clamping ring 3 is fixed with a flexible inner ring 301. The flexible inner ring 301 is fixed to the bottom of the outer shell 1 and is located outside the opening. The bottom ends of the clamping ring 3 and the flexible inner ring 301 are jointly fixed with a flexible contact ring 302. When the outer shell 1 is working, it is threadedly connected to the corresponding heat sink opening through the bottom opening. The clamping ring 3 is pressed between the flexible inner ring 301 and the periphery of the heat sink opening, and is movably connected to the corresponding heat sink through the flexible contact ring 302.

[0032] The operation process of this embodiment is as follows: During operation, after the outer shell 1 is installed on the radiator opening, the clamping ring 3 is pressed onto the radiator. After the flexible contact ring 302 at the bottom of the clamping ring 3 is pressed onto the radiator, the radiator and the clamping ring 3 are pressed together, so that the gap between the outer shell 1 and the radiator is initially sealed, increasing the sealing effect between the outer shell 1 and the radiator. During the process of installing the outer shell 1 on the radiator opening, the flexible inner ring 301 guides the radiator opening into the outer shell 1.
