Description

Technical Field

[0001] The utility model relates to the technical field of rubber rings, and particularly relates to a high-temperature ethylene propylene rubber ring. Background Art

[0002] A rubber ring is a sealing part made of rubber material, usually used to connect parts of mechanical equipment to prevent fluid or gas leakage, prevent dust from entering, reduce friction, etc. In addition, the rubber ring also has some chemical resistance, corrosion resistance and high temperature resistance properties, and is widely used. An ethylene propylene rubber ring refers to a rubber ring prepared from ethylene propylene as raw materials.

[0003] The existing rubber rings have the following disadvantages in the use process: The rubber rings are generally used as sealing parts between pipelines. In some application working conditions, they need to be used in high-temperature environments. However, affected by high temperature for a long time, the rubber rings will accelerate their aging and affect their sealing performance. Therefore, we propose a high-temperature ethylene propylene rubber ring. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a high-temperature ethylene propylene rubber ring. By arranging heat dissipation components inside and outside the rubber ring body, the heat dissipation inside the rubber ring is accelerated, and the influence on the rubber ring under high-temperature working conditions is reduced, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-temperature ethylene propylene rubber ring, comprising a rubber ring body, an inner corrugated ring is embedded inside the rubber ring body, an outer corrugated ring is sleeved on the outer periphery of the rubber ring body, and a corrugated connecting strip is welded between the inner corrugated ring and the outer corrugated ring and the corrugated connecting strip penetrates through the rubber ring body.

[0007] Furthermore, convex rings are integrally formed on both sides of the surface of the rubber ring body; convex ring structures are integrally formed on both sides of the rubber ring body. When the rubber ring body is installed, the convex ring structures are inserted into the ring grooves inside the connecting piece to play a role in increasing the sealing area.

[0008] Furthermore, the materials of the rubber ring body and the convex rings are both ethylene propylene; because the main chain of ethylene propylene rubber is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, it has excellent ozone resistance, heat resistance and aging resistance.

[0009] Furthermore, the materials of the inner corrugated ring, the outer corrugated ring and the corrugated connecting strip are all copper; the copper sheet material has good heat conduction characteristics.

[0010] Compared with the prior art, the utility model has the following beneficial effects: convex ring structures are arranged on both sides of the surface of the rubber ring body. When the rubber ring body is installed, the convex ring structures are inserted into the annular grooves inside the connecting piece to increase the sealing area. An inner corrugated ring is built inside the rubber ring body, an outer corrugated ring is arranged outside the rubber ring body, and the connection between the outer corrugated ring and the inner corrugated ring is connected by a corrugated connecting strip. When used under high-temperature working conditions, the high temperature inside the rubber ring body will be conducted through the inner corrugated ring and the corrugated connecting strip to the outer corrugated ring and dissipated by the outer corrugated ring, reducing the temperature inside the rubber ring body, thereby reducing the influence of the high-temperature environment on the rubber ring and prolonging its service life. The inner corrugated ring, the outer corrugated ring and the corrugated connecting strip all adopt corrugated structures, which have deformation space and do not affect the deformation of the rubber ring body. At the same time, the corrugated structure of the outer corrugated ring can also increase the heat dissipation area and improve the heat dissipation effect. Description of the Drawings

[0015] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0016] As Figures 1-3 shown, a high-temperature ethylene propylene rubber ring includes a rubber ring body 1. An inner corrugated ring 3 is embedded inside the rubber ring body 1. An outer corrugated ring 4 is sleeved on the outer periphery of the rubber ring body 1. A corrugated connecting strip 5 is welded between the inner corrugated ring 3 and the outer corrugated ring 4, and the corrugated connecting strip 5 penetrates through the rubber ring body 1.

[0017] Among them, convex rings 2 are integrally formed on both sides of the surface of the rubber ring body 1; convex ring 2 structures are integrally formed on both sides of the rubber ring body 1. When the rubber ring body 1 is installed, the convex ring 2 structures are inserted into the annular grooves inside the connecting piece to increase the sealing area.

[0018] Among them, the rubber ring body 1 and the convex ring 2 are made of EPDM, and the inner corrugated ring 3, the outer corrugated ring 4 and the corrugated connecting strip 5 are made of copper; EPDM rubber has excellent ozone resistance, heat resistance and aging resistance because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, and the copper sheet material has good thermal conductivity.

[0019] It should be noted that the utility model is a high-temperature EPDM rubber ring. When in use, convex ring 2 structures are provided on both sides of the surface of the rubber ring body 1. When the rubber ring body 1 is installed, the convex ring 2 structure is inserted into the ring groove inside the connecting piece to increase the sealing area. An inner corrugated ring 3 is built into the rubber ring body 1, and an outer corrugated ring 4 is arranged outside the rubber ring body 1. The connection between the outer corrugated ring 4 and the inner corrugated ring 3 is connected by a corrugated connecting strip 5. When used under high-temperature working conditions, the internal high temperature of the rubber ring body 1 will be transmitted to the outer corrugated ring 4 through the inner corrugated ring 3 and the corrugated connecting strip 5 and dissipated by the outer corrugated ring 4, thereby reducing the temperature inside the rubber ring body 1, thereby reducing the influence of the high-temperature environment on the rubber ring and extending its service life. The inner corrugated ring 3, the outer corrugated ring 4 and the corrugated connecting strip 5 all adopt a corrugated structure and have deformation space, which does not affect the deformation of the rubber ring body 1. At the same time, the corrugated structure of the outer corrugated ring 4 can also increase the heat dissipation area and improve the heat dissipation effect.

[0020] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
