Description

Technical Field

[0001] This utility model relates to the field of heat pipe sealing technology, and in particular to a sealing gasket for the connection end of a finned heat pipe. Background Technology

[0002] Finned heat pipes, also known as heat exchange tubes, are heat exchange elements used to enhance heat transfer. By increasing the surface area, they improve heat exchange efficiency and are suitable for high-temperature, high-pressure, and corrosive environments in industries such as boilers, power, and metallurgy. Their core function is to reduce contact thermal resistance and they have anti-corrosion and wear-resistant properties. They are often used in waste heat recovery and heat exchange equipment. Finned heat pipes are usually connected by flanges, and gaskets are installed on the flanges to prevent internal liquid leakage.

[0003] However, existing technologies have some problems: although existing finned heat pipes have gaskets at the connection ends to improve the sealing effect, the existing gaskets have simple structures and achieve sealing by the mutual compression of the flanges on both sides. The single plane or corrugated structure of the gasket leads to uneven stress distribution on the sealing surface, which can easily cause medium penetration due to insufficient stress. In addition, temperature fluctuations inside the pipe cause thermal expansion and contraction of the flange. Traditional gaskets lack an active compensation mechanism, which makes them prone to leakage after long-term use. Therefore, we propose a sealing gasket for the connection end of finned heat pipes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing gasket for the connection end of a finned heat pipe. By setting a gasket ring, an anti-overflow ring, and a semi-circular piece, the sealing effect of the sealing gasket body is improved.

[0005] The purpose of this utility model is achieved as follows: a sealing gasket for the connection end of a finned heat pipe includes a sealing gasket body, a through hole on the surface of the sealing gasket body, a gasket ring fixedly installed on the surface of the sealing gasket body, the gasket ring having a semi-circular cross-section, an anti-overflow ring fixedly installed on the surface of the sealing gasket body, a semi-circular piece fixedly installed on the sealing gasket body outside the through hole, a baffle plate fixedly installed on the semi-circular piece, and a circular ring fixedly installed at the edge of the sealing gasket body.

[0006] Optionally, the inner wall of the ring is provided with a flange, and the flange is generally wavy.

[0007] Optionally, the baffle is inclined, and a cavity is formed between the semicircular plate and the baffle.

[0008] Optionally, the number of washer rings is two, and the two washer rings are arranged concentrically.

[0009] Optionally, the anti-overflow ring is disposed between two gasket rings, and the cross-section of the anti-overflow ring is V-shaped.

[0010] Optionally, a retaining ring is fixedly installed on the inner wall of the through hole, and the retaining ring is disposed in the middle of the inner wall of the through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the arrangement of a gasket, an anti-overflow ring, a semi-circular plate, a baffle plate, and a circular ring, allows the circular ring to seal the flange edge after the gasket body is installed. The gasket can be squeezed into the groove reserved on the flange surface. The anti-overflow ring, after being squeezed and deformed, can improve the sealing effect. Thus, the elasticity of the gasket and anti-overflow ring after being squeezed can compensate for the deformation of the flange due to thermal expansion and contraction. At the same time, the baffle plate is squeezed and adhered to the semi-circular plate. The semi-circular plate and the baffle plate further improve the sealing of the through hole, preventing liquid in the pipe from leaking through the through hole, thereby jointly improving the sealing effect.

[0019] 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 protection scope of the present utility model.

[0020] like Figures 1 to 4As shown in the figure, the present invention provides a sealing gasket for the connection end of a finned heat pipe, including a sealing gasket body 1, a through hole 2 on the surface of the sealing gasket body 1, a gasket ring 3 fixedly installed on the surface of the sealing gasket body 1, the gasket ring 3 having a semi-circular cross-section, an anti-overflow ring 4 fixedly installed on the surface of the sealing gasket body 1, a semi-circular piece 5 located outside the through hole 2 fixedly installed on the sealing gasket body 1, a baffle 6 fixedly installed on the semi-circular piece 5, and a circular ring 7 fixedly installed at the edge of the sealing gasket body 1.

[0021] When connecting the finned heat pipe, the sealing gasket body 1 is fitted onto the flange at the end of the heat pipe through the ring 7, and then the connection is achieved by bolts passing through the flange and fixing it to the through hole 2. The gasket ring 3 can be squeezed into the groove reserved on the surface of the flange. The anti-overflow ring 4 can improve the sealing effect after being squeezed and deformed. At the same time, the baffle 6 is squeezed and adhered to the semi-circular plate 5. The semi-circular plate 5 and the baffle 6 further improve the sealing of the through hole 2, preventing the liquid in the pipe from leaking through the through hole 2, thereby improving the sealing effect.

[0022] Furthermore, the inner wall of the ring 7 is provided with a flange 8, which is wavy in shape.

[0023] With the design of flange 8, when ring 7 is fitted onto flange, flange 8 is compressed and deformed, thereby improving the stability of ring 7 and gasket body 1 fitted onto flange and preventing them from falling off during installation. At the same time, the presence of flange 8 can also improve the sealing effect of ring 7 on flange edge.

[0024] Furthermore, the baffle 6 is inclined, and a cavity 9 is formed between the semicircular piece 5 and the baffle 6.

[0025] Because the baffle 6 is inclined, when the sealing gasket body 1 is installed between two flanges and squeezed, the baffle 6 can fit onto the semicircular piece 5 to eliminate the cavity 9. After the baffle 6 and the semicircular piece 5 are fitted together, they form a stepped shape, which can further improve the sealing effect.

[0026] Furthermore, there are two washer rings 3, and the two washer rings 3 are set concentrically.

[0027] The design of the two gaskets 3 allows for a double seal when compressed, thus providing double protection near the heat pipe and improving the sealing effect.

[0028] Furthermore, the anti-overflow ring 4 is disposed between the two gasket rings 3, and the cross-section of the anti-overflow ring 4 is V-shaped.

[0029] When the sealing gasket body 1 is installed between two flanges and squeezed, the anti-overflow ring 4 is also squeezed. Since the anti-overflow ring 4 is V-shaped, the two sides of the anti-overflow ring 4 are squeezed and move closer to the gaskets 3 on both sides to fit together. Thus, even if there is a small leak in the first gasket 3 seal, the anti-overflow ring 4 can block or greatly reduce it, forming a labyrinth seal effect, thereby significantly reducing the possibility of liquid leakage to the outside.

[0030] Furthermore, a retaining ring 10 is fixedly installed on the inner wall of the through hole 2, and the retaining ring 10 is located in the middle of the inner wall of the through hole 2.

[0031] With the setting of the retaining ring 10, after the bolt passes through the through hole 2, the retaining ring 10 can adhere to the surface of the bolt, thereby further preventing liquid from leaking out of the through hole 2, and thus further improving the sealing performance.

[0032] Working principle and usage process of this utility model:

[0033] When connecting the finned heat pipe, the sealing gasket body 1 is fitted onto the flange at the end of the heat pipe via the ring 7. When the ring 7 is fitted onto the flange, the flange 8 is compressed and deformed, thereby improving the stability of the ring 7 and the sealing gasket body 1 on the flange and preventing them from falling off during installation. The presence of the flange 8 also improves the sealing effect of the ring 7 at the flange edge. The connection is then achieved by bolts passing through the flange and fixing it to the through hole 2. After the bolts pass through the through hole 2, the retaining ring 10 adheres to the bolt surface, preventing liquid leakage from the through hole 2 and further improving the sealing performance. After connection... The gasket 3 can be squeezed into the groove reserved on the flange surface, and the anti-overflow ring 4 is squeezed and deformed. Since the anti-overflow ring 4 is V-shaped, the two sides of the anti-overflow ring 4 are squeezed and move closer to the gasket 3 on both sides to fit together. Thus, even if there is a small leak in the first gasket 3 seal, the anti-overflow ring 4 can block or greatly reduce it, forming a labyrinth seal effect, thereby significantly reducing the possibility of liquid leakage to the outside. At the same time, the baffle 6 is squeezed and fitted onto the semi-circular plate 5. After the baffle 6 and the semi-circular plate 5 are fitted together, they form a stepped shape, which can further improve the sealing effect and prevent the liquid in the pipe from leaking through the through hole 2, thereby improving the sealing effect.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
