Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a high-temperature and high-pressure resistant sealing ring. Background Technology

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases. It is usually made of elastic materials and has a sealing function. The choice of material is of great importance to its sealing performance and service life, and the performance of the material directly affects the performance of the sealing ring.

[0003] Existing sealing rings are often integrally molded with a relatively simple structure. They are prone to deformation under high temperature and high pressure working environment for a long time, which affects subsequent use. In view of this, we propose a high temperature and high pressure resistant sealing ring. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a high-temperature and high-pressure resistant sealing ring to solve the technical problem that the existing sealing rings are often integrally molded, have a relatively simple structure, and are prone to deformation in high-temperature and high-pressure working environments for a long time, thus affecting subsequent use.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a high temperature and high pressure resistant sealing ring, including a sealing ring assembly, wherein the sealing ring assembly is provided with a plurality of auxiliary mechanisms in a ring shape;

[0006] The sealing ring assembly includes a first sealing ring, with an internal interlayer. A plurality of guide grooves are uniformly and annularly formed on one side of the inner wall of the first sealing ring. A second sealing ring is held in the internal interlayer of the first sealing ring. A plurality of guide blocks are uniformly and annularly fixed on the outer side of the second sealing ring. A set of grooves are symmetrically formed on the surface of the second sealing ring, and a pull strip is fixed inside the groove.

[0007] Preferably, the fluid cavity in the middle of the first sealing ring is frustum-shaped, and the diameter of the fluid cavity in the middle of the first sealing ring gradually increases from left to right.

[0008] Preferably, the second sealing ring forms an engaging structure with the guide block and the guide groove, and the number of guide blocks and guide grooves is the same.

[0009] Preferably, the auxiliary mechanism includes a first T-shaped block, a plurality of the first T-shaped blocks are evenly distributed in a ring on the surface of the second sealing ring, a spring is sleeved on the outer side of the first T-shaped block, and a plurality of second T-shaped blocks are evenly distributed in a ring on the inner interlayer wall of the first sealing ring.

[0010] Preferably, the first T-blocks and the second T-blocks are symmetrically arranged, and the spring is sleeved on the outside of the first T-blocks and the second T-blocks on the same central axis.

[0011] Preferably, the second T-block forms an elastic structure with the first T-block via a spring, and there is a displaceable space between the symmetrical first T-block and the second T-block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively accelerates the flow of fluid from right to left through a frustum-shaped fluid cavity, thereby reducing pressure and allowing the first sealing ring to better adapt to high-pressure environments. The guide groove on the inner side of the first sealing ring and the guide block on the outer side of the second sealing ring restrain each other, reducing the possibility of ring distortion. Since the first sealing ring has an internal interlayer, its overall heat capacity is lower than that of a solid rubber ring. Under the same heating conditions, the first sealing ring heats up faster and has a greater temperature difference with the surrounding environment, thus being more conducive to heat dissipation.

[0014] 2. In this utility model, when the fluid impacts the sealing ring assembly, the rubber material of the sealing ring assembly itself can provide corresponding elastic compensation. At the same time, the spring between the first T-block and the second T-block is compressed, providing a certain elastic support and buffer. After the impact stops, the spring's rebound force effectively drives the first T-block and the second T-block back to their original positions. The spring can adapt to the deformation of the sealing ring assembly through its own compression or extension, continuing to provide a certain pressure and support force, so that the sealing ring assembly can still function well.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] A high-temperature and high-pressure resistant sealing ring, see [link / reference] Figures 1 to 4 It includes a sealing ring assembly 1, and the sealing ring assembly 1 has a plurality of auxiliary mechanisms 2 uniformly arranged in a ring shape inside the sealing ring assembly 1;

[0024] The sealing ring assembly 1 includes a first sealing ring 101, which has an internal interlayer. The fluid cavity in the middle of the first sealing ring 101 is frustoconical, and the diameter of the fluid cavity in the middle of the first sealing ring 101 gradually increases from left to right. A plurality of guide grooves 102 are uniformly and annularly formed on the inner wall of one side of the first sealing ring 101. A second sealing ring 103 is held in the internal interlayer of the first sealing ring 101. A plurality of guide blocks 104 are uniformly and annularly fixed on the outer side of the second sealing ring 103. Furthermore, the second sealing ring 103 forms an engaging structure with the guide grooves 102 through the guide blocks 104. The number of guide blocks 104 and guide grooves 102 is the same. A set of grooves 105 are symmetrically formed on the surface of the second sealing ring 103, and a pull strip 106 is fixed inside the groove 105. This invention effectively accelerates the flow of fluid from right to left through a frustum-shaped fluid cavity, thereby reducing pressure and allowing the first sealing ring 101 to better adapt to high-pressure environments. The guide groove 102 on the inner side of the first sealing ring 101 and the guide block 104 on the outer side of the second sealing ring 103 restrain each other, reducing the possibility of ring body twisting and deformation. Since the first sealing ring 101 has an internal interlayer, the overall heat capacity of the first sealing ring 101 is lower than that of a solid rubber ring. Under the same heating conditions, the first sealing ring 101 heats up faster and has a greater temperature difference with the surrounding environment, thus being more conducive to heat dissipation.

[0025] It is worth noting that the auxiliary mechanism 2 includes a first T-shaped block 201, a plurality of first T-shaped blocks 201 are evenly distributed in a ring on the surface of the second sealing ring 103, a spring 202 is sleeved on the outside of the first T-shaped block 201, and a plurality of second T-shaped blocks 203 are evenly distributed in a ring on the inner interlayer wall of the first sealing ring 101. The plurality of first T-shaped blocks 201 and the plurality of second T-shaped blocks 203 are symmetrical to each other. The spring 202 is sleeved on the outside of the first T-shaped blocks 201 and the second T-shaped blocks 203 on the same central axis. Furthermore, the second T-shaped blocks 203 form an elastic structure with the first T-shaped blocks 201 through the spring 202, and there is a displacement space between the symmetrical first T-shaped blocks 201 and the second T-shaped blocks 203. In this invention, when fluid impacts the sealing ring assembly 1, the rubber material of the sealing ring assembly 1 can provide corresponding elastic compensation. At the same time, the spring 202 between the first T-block 201 and the second T-block 203 is compressed, providing a certain elastic support and buffer. After the impact stops, the rebound force of the spring 202 effectively drives the first T-block 201 and the second T-block 203 back to their original positions. The spring 202 can adapt to the deformation of the sealing ring assembly 1 through its own compression or extension, and continue to provide a certain pressure and support force, so that the sealing ring assembly 1 can still play a good role.

[0026] Working principle: The fluid flowing from right to left is accelerated through the frustum-shaped fluid cavity, thereby reducing pressure and allowing the first sealing ring 101 to better adapt to high-pressure environments. The guide groove 102 on the inner side of the first sealing ring 101 and the guide block 104 on the outer side of the second sealing ring 103 restrain each other, reducing the possibility of ring distortion. Because the first sealing ring 101 has an internal interlayer, its overall heat capacity is lower than that of a solid rubber ring. Under the same heating conditions, the first sealing ring 101 heats up faster and has a larger temperature difference with the surrounding environment, thus facilitating heat dissipation and better adapting to high-temperature environments. When the fluid impacts the sealing ring assembly 1, the sealing ring assembly... 1. The rubber material itself can provide corresponding elastic compensation. At the same time, the spring 202 between the first T-block 201 and the second T-block 203 is compressed, providing a certain elastic support and buffer. After the impact stops, the rebound force of the spring 202 drives the first T-block 201 and the second T-block 203 to return to their original positions. The spring 202 can adapt to the deformation of the sealing ring assembly 1 through its own compression or extension, and continue to provide a certain pressure and support force, so that the sealing ring assembly 1 can still play a good role. Subsequently, by pulling the pull bar 106, the second sealing ring 103 is separated from the first sealing ring 101, which facilitates the selective replacement of the spring 202 or the partial sealing ring assembly 1, reducing the replacement cost.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
