Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piston rings, and more specifically to a piston ring with high sealing performance. Background Art
[0002] The piston ring is a metal elastic ring with a large outward expansion deformation. During the assembly process, the piston ring is placed in the cross section and its corresponding annular groove. During the reciprocating and rotational motion, the piston ring can rely on the pressure difference of the gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and between the ring and one side of the ring groove.
[0003] The piston ring of an internal combustion engine is a key component that is mainly used to ensure the sealing between the piston and the cylinder. It is usually made of metal material, installed on the piston, and in close contact with the cylinder wall, which can effectively seal the gas and lubricating oil.
[0004] In the prior art, as the piston ring moves back and forth at high speed up and down in the cylinder with the piston, there is constant friction between the piston ring body and the cylinder wall, causing the piston ring to wear. The wear of the piston ring causes a poor seal between the piston ring and the piston ring groove and the cylinder wall, resulting in air leakage. At the same time, the piston is prone to deformation under high temperature and high pressure conditions, resulting in uneven gaps between the pistons, causing the piston ring to get stuck in the cylinder, resulting in a poor seal between the piston ring and the cylinder wall, leading to gas and lubricating oil leakage.
[0005] Therefore, in order to solve the above technical problems, the present application proposes a piston ring with high sealing performance. Utility Model Content

[0007] To achieve the above object, the utility model provides the following technical solution: a piston ring with high sealing performance, comprising an inner ring and an outer ring, wherein two symmetrical end points of the outer side of the inner ring are fixedly connected with plug-in blocks;
[0008] By setting the inner and outer rings, during use, the inner and outer rings are connected by the plug-in block and the plug-in groove. By setting the inner and outer rings, the sealing of the piston ring and the cylinder can be effectively improved, and the leakage of gas and lubricating oil can be reduced. At the same time, by setting the inner and outer rings, the problem of loose sealing between the piston ring, the piston ring groove and the cylinder wall caused by wear caused by friction between the piston ring body and the cylinder wall can be effectively solved, thereby improving the sealing of the piston ring.
[0009] Preferably, the upper end surface and the lower end surface of the outer ring are both fixedly connected with a rubber ring;
[0010] By providing a rubber ring, the rubber ring and the outer ring are used together during use, so that when the piston moves up and down at high speed in the cylinder, the rubber ring can effectively reduce the friction between the ring body of the outer ring and the cylinder wall. At the same time, the rubber ring has a certain elasticity, which can help the piston to better adapt to different temperature and pressure conditions during use, and effectively solves the problem of the piston being stuck in the cylinder body due to deformation when the piston is in a high temperature and high pressure environment, thereby improving the sealing performance of the piston ring.
[0011] Preferably, two symmetrical end points of the inner side of the outer ring are provided with plug-in grooves;
[0012] By setting the plug-in groove, during use, the plug-in groove and the plug-in block are used together to achieve the connection between the inner ring and the outer ring. By connecting the inner ring and the outer ring, the wear of the same ring body during movement can be reduced, thereby extending the service life of the piston ring. At the same time, the adaptability of the piston to different high temperature and high pressure environments is improved to a certain extent, thereby improving the sealing performance of the piston ring.
[0013] Preferably, a plug-in block is plugged into the plug-in slot;
[0014] By setting up the plug-in block and using the plug-in block and the plug-in groove together during use, the connection between the inner ring and the outer ring can be achieved. By connecting the outer ring of the inner ring, the movement of the piston in the cylinder can be better guided to ensure the stability of the piston on the movement trajectory, which helps to reduce the friction between the piston and the cylinder, reduces the wear of the piston ring and the cylinder body, and extends the service life of the piston, while also improving the movement efficiency of the piston.
[0015] Preferably, the positions where the plug-in blocks are arranged on the upper end surface and the lower end surface of the inner ring are fixedly connected with rubber strips, and the shape of the rubber strips is annular;
[0016] By arranging a rubber block on the end face of the inner ring where the plug-in block is arranged, during use, the rubber block and the inner ring are used together to improve the sealing performance of the piston ring during the movement of the piston, which helps to reduce the loss of gas and lubricating oil and improve the overall efficiency of the internal combustion engine.
[0017] Preferably, the surfaces of the inner ring and the outer ring are coated with an anti-rust coating;
[0018] By providing an anti-rust coating, the corrosion of the inner ring and the outer ring can be effectively reduced during use, thereby extending the service life of the piston ring and, to a certain extent, reducing the friction loss of the piston ring during use.
[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0031] Two symmetrical end points of the inner side of the outer ring 1 are provided with plug-in grooves 5;
[0032] By providing the plug-in groove 5, during use, the plug-in groove 5 and the plug-in block 6 are used in combination to achieve the connection between the inner ring 2 and the outer ring 1.

[0033] A plug-in block 6 is plugged into the plug-in slot 5;
[0034] By setting the plug-in block 6, the plug-in block 6 and the plug-in groove 5 are used in conjunction with each other during use to achieve the connection between the inner ring 2 and the outer ring 1. By connecting the outer ring 1 to the inner ring 2, the movement of the piston in the cylinder can be better guided to ensure the stability of the piston on the movement trajectory, which helps to reduce the friction between the piston and the cylinder, reduces the wear of the piston ring and the cylinder body, and extends the service life of the piston.
