Description

Technical Field

[0001] The utility model relates to the technical field of seals, in particular to wear-resistant and pressure-resistant seals. Background Technique

[0002] A seal is an important component material or part, and its main function is to prevent the leakage of fluids or solid particles from adjacent joint surfaces and prevent the intrusion of external impurities such as dust and moisture into the interior of machinery and equipment. Seals are usually made of rubber, plastic, metal or other special materials, which have excellent sealing performance, wear resistance, pressure resistance, corrosion resistance and anti-aging properties. Seals are widely used in many fields such as automobiles, machinery, chemical industry, petroleum, pharmaceuticals, etc. In the machinery field, seals are used for the sealing of various pumps, valves, hydraulic cylinders and other equipment to prevent medium leakage and pollution.

[0003] After retrieval, the Chinese patent with the application number CN202222932494.X discloses a rubber seal for water supply and drainage pipelines. In view of the fact that the rubber seal becomes hard and loses its good elastic effect due to the decrease in temperature when used in winter, resulting in a weakened sealing effect, therefore, we propose a rubber seal for water supply and drainage pipelines. So, a ring-shaped first rubber strip and a second rubber strip are arranged in the inner groove inside the rubber ring, which can make the inside of the rubber ring have better elasticity and a deformable interval, and also have better elasticity when the rubber material weakens in winter. Cooperating with the convex strips on both surfaces of the rubber ring, it ensures that there is always a good sealing contact effect with the inner wall of the joint during use, thereby maintaining its good sealing effect.

[0004] During the use of the above-mentioned seal, it is convenient to reduce the loss of the sealing effect due to the hardening of the seal. However, the seals in existing pipelines are usually used for the sealing of fluids. When the fluid flows, its wear resistance and pressure resistance are usually relatively weak. Usually, the pipeline will vibrate due to the flowing pressure. When the pipeline vibrates, it often rubs against adjacent components. If the wear resistance of the seal is poor, it will cause its rapid wear, thereby leading to problems such as leakage, affecting the normal operation of the equipment, and reducing the service life of the seal at the same time.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] As shown in the Figure 1-6 accompanying drawings, an embodiment provided by the present utility model: a wear-resistant and pressure-resistant seal, including a housing 1, and a wear-resistant component is arranged inside the housing 1;

[0033] The wear-resistant component includes a sealing ring 2, the sealing ring 2 is arranged inside the housing 1, an installation ring 3 is fixedly connected inside the sealing ring 2, a plurality of installation grooves 4 are opened inside the installation ring 3, the plurality of installation grooves 4 are distributed in a circular array inside the installation ring 3, a spring 5 is fixedly connected inside the installation groove 4, a protective shell 6 is slidably connected inside the installation groove 4, the spring 5 is arranged inside the protective shell 6, one end of the protective shell 6 is provided with a sealing gasket 7, the sealing gasket 7 is arranged at one end of the spring 5, a wear-resistant gasket 8 is arranged on one side of the sealing gasket 7, two wear-resistant rings 9 are arranged on the inner wall of the sealing ring 2, both the wear-resistant gasket 8 and the wear-resistant rings 9 are made of hydrogenated nitrile rubber, the sealing gasket 7 is made of chloroprene rubber, the installation ring 3 is used for installing the spring 5, the protective shell 6 plays a role in protecting and limiting the spring 5, the wear-resistant gasket 8 is convenient for protecting the sealing gasket 7, and the wear-resistant rings 9 play a role in protecting the inner wall of the sealing ring 2.

[0034] As shown in the Figure 5 accompanying drawings, a disassembly and assembly component is arranged on the lower surface of the housing 1, the disassembly and assembly component includes a first limiting ring 10, the first limiting ring 10 is fixedly connected to the lower surface of the housing 1, a threaded sleeve 11 is fixedly connected to the upper surface of the housing 1, a hole groove 16 is opened on the upper surface of the housing 1, the first limiting ring 10 is convenient for limiting the position of the sealing ring 2, and the threaded sleeve 11 is used for connecting a threaded rod 12.

[0035] As shown in the Figure 1 accompanying drawings, a threaded rod 12 is threadedly connected inside the threaded sleeve 11, one end of the threaded rod 12 is fixedly connected with a knob 13, the other end of the threaded rod 12 is rotatably connected with a backing plate 14, a second limiting ring 15 is fixedly connected to the lower surface of the backing plate 14, a limiting rod 17 is fixedly connected to the upper surface of the limiting ring 15, the limiting rod 17 is slidably connected inside the hole groove 16, a replacement groove 18 is opened on one side of the housing 1, the threaded rod 12 is convenient for pushing the movement of the first limiting ring 10, and the limiting rod 17 plays a role in limiting and stabilizing the movement of the second limiting ring 15.

[0036] Working principle: After passing the pipeline through the inside of the sealing ring 2, connect the sealing member to the outer wall of the pipeline. When the pipeline vibrates, the vibration force will squeeze the wear-resistant pads 8 in different directions. Under the action of the spring 5 inside the installation groove 4, it is convenient for the spring 5 to push the sealing pad 7, so that the sealing pad 7 transmits the driving force to the wear-resistant pad 8. It is convenient for the wear-resistant pad 8 to be in close contact with the vibrating pipeline under the pushing action of the spring 5, which is convenient for buffering the vibration force generated by the pipeline to a certain extent, conducive to improving the pressure resistance performance of the sealing member. And under the action of the wear-resistant pad 8 and the wear-resistant ring 9, it is convenient to increase the wear resistance of the sealing member when friction occurs due to the vibration contact between the pipeline and the sealing member, which is conducive to reducing the phenomenon of damage to the sealing member caused by long-term contact friction;

[0037] When the sealing member needs to be replaced, first take out the outer shell 1 from the inner wall of the pipeline, and then turn the knob 13. The rotation of the knob 13 drives the threaded rod 12 to rotate internally in the threaded sleeve 11. When the threaded rod 12 rotates, it is convenient to drive the second limit ring 15 to rise on the inner wall of the outer shell 1 through the backing plate 14. Thus, when the second limit ring 15 rises, it drives the limit rod 17 to slide and rise inside the hole groove 16, so that the second limit ring 15 moves to the top of the inner wall of the outer shell 1. Then, take out the sealing ring 2 from the replacement groove 18 by hand. Then, insert the sealing ring 2 to be replaced into the upper surface of the first limit ring 10 from the inside of the replacement groove 18, and then reverse-turn the knob 13 to press down the second limit ring 15 to fix the sealing ring 2, thereby facilitating the replacement of the sealing member and improving the convenience of the replacement process.
