Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber products, in particular to a rubber sealing ring and a sealing structure with the rubber sealing ring. Background Technique
[0002] A rubber sealing ring is an annular cover composed of one or several parts, which can prevent water or lubricating oil from leaking out and foreign objects from invading. It is used for installation in various industries such as chemical industry, food, medical treatment, machinery, etc. It plays a sealing role in a static or moving state under specified temperature, pressure, and different liquids and gases.
[0003] Generally, the rubber sealing ring is in a circular ring shape. When installing and fixing, since the fixing port is an arc structure and is relatively smooth, the friction force with the installed equipment is small. Therefore, under the action of a large external force, the rubber sealing ring is likely to loosen and fall off, thereby affecting the sealing effect of the equipment and causing problems with the equipment. Content of the Utility Model

Therefore, under the action of a large external force, the rubber sealing ring is likely to loosen and fall off, thereby affecting the sealing effect of the equipment and causing problems with the equipment as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A rubber sealing ring, including a sealing ring body, a sealing component is arranged on the top of the sealing ring body.

By installing the sealing component, during installation, through the conical structure of the upper reinforcement block and the lower reinforcement block, the device to be sealed can be clamped, increasing the friction force with the equipment, making its fixing effect better, and avoiding the situation that the sealing effect is affected by external forces. And through the upper sealing strip and the lower sealing strip, by using their elastic characteristics, the gap between the rubber sealing ring and the equipment can be filled during installation and fixing, increasing the sealing effect of the rubber sealing ring and improving the practicability of the device.
[0006] Further preferably, for the sealing structure with the rubber sealing ring, a protection component is arranged inside the upper gasket. The protection component includes an anti-corrosion coating which is fixedly connected to the upper surface of the upper gasket. High-temperature resistant fluororubber is fixedly connected inside the upper gasket. By installing the protection component, the anti-corrosion coating outside the rubber sealing ring can effectively prevent the erosion of corrosive media, improving the service life of the rubber sealing ring. And the high-temperature resistant fluororubber inside can maintain its elasticity and durability at a relatively high temperature, being applicable to various high-temperature working environments.
[0007] Further preferably, a heat-insulating coating is fixedly connected inside the upper gasket, and a reinforcing layer is fixedly connected inside the upper gasket. By installing the protection component, the heat-insulating coating inside can maintain the internal temperature, avoiding the reduction of the elasticity of the rubber caused by drastic temperature changes. And the reinforcing layer inside can play a supporting role for the external rubber sealing ring, preventing the rubber sealing ring from deforming and being damaged under a large external force, enhancing the structural strength and durability of the sealing ring.
[0008] Further preferably, a protective film is fixedly connected to the bottom of the sealing ring body, and a reinforcing column is fixedly connected inside the upper gasket. By installing the reinforcing column, it can play a role in fixing and supporting the rubber sealing ring, and has good anti-friction and wear resistance, and can also play a buffering role.
[0009] Further preferably, a central hole is opened at the top of the upper gasket, and a protruding ring is fixedly connected to the inner wall of the upper gasket. By installing the protruding ring, when sealing through the inside of the rubber sealing ring, the elastic force of the protruding ring can be used to fill the gap between the protruding ring and the device, improving the sealing performance.
