Because the gasket body 1 is provided with openings 8 which are uniformly distributed and communicated with the outer edge 2, the oil under pressure flows into the hollow outer edge 2 through the openings 8, and then flows into the hollow side pad 9 which is in communication with the hollow outer edge 2.

When the top edge of the equipment opening 8 extrudes the compression ring 6, the compression ring 6 made of elastic rubber material is compressed to provide power for the oil in the annular groove 7 to flow, and the side pad 9 made of elastic rubber material expands after the oil flows in. The expanded side pad 9 tightly fits the side edge of the equipment, thereby further improving the sealing effect. The support bars 4 and the connecting bars 5 are made of hard rubber material, the support bars 4 stably support the outer edge 2 and the inner edge 3, the connecting bars 5 enhance the rigidity between the support bars 4, thereby improving the overall rigidity of the outer edge 2 and the inner edge 3, enhancing the pressure resistance of the gasket when being pressed, and ensuring the stability of the sealing process.

[0030] The opening 8 is provided in the form of an arc-shaped strip, and the opening 8 is provided with at least two groups of symmetrical openings;

[0032] The inside of the outer edge 2 is hollow and arranged in a ring shape;

[0033] The inside of the outer edge 2 is hollow and arranged in a ring shape, when the oil body flows from the annular groove 7 into the outer edge 2 through the opening 8, the hollow structure of the ring provides sufficient and uniform storage space for the oil body, and the oil body can quickly spread in the annular space after entering the outer edge 2, quickly guide the oil body to the side pad 9, and make the side pad 9 quickly expand and tightly fit the side edge of the equipment, thereby improving the sealing effect and ensuring the timeliness and effectiveness of the equipment sealing.

[0034] At least two groups of connecting strips 5 are arranged between adjacent support strips 4;

[0035] At least two groups of connecting strips 5 are arranged between adjacent support strips 4, further improving the rigidity of the outer edge 2 and the inner edge 3 of the ring, and the outer edge 2 and the inner edge 3 of the ring with enhanced rigidity are not easy to deform under pressure, always tightly fit the top edge of the equipment, effectively prevent fluid leakage caused by the deformation of the gasket, ensure the stability of the sealing, and prolong the service life of the gasket.

[0036] Working principle:

[0037] In use, the gasket body 1 is first fixedly installed on the cover plate of the equipment, when the cover plate of the equipment is closed to seal the opening 8 of the equipment, the cavity between the outer edge 2 and the inner edge 3 of the gasket body 1 is gradually inserted on the opening 8 of the equipment, as the cavity moves, the top edge of the equipment opening 8 extrudes the compression ring 6, the compression ring 6 is compressed and deformed to extrude the annular groove 7, the space of the annular groove 7 is extruded and compressed to become smaller, and the oil in the groove is subjected to pressure. Because the gasket body 1 is provided with uniformly distributed openings 8 connected with the outer edge 2, the oil under pressure flows into the hollow outer edge 2 through these openings 8, and then flows into the hollow side pad 9 connected therewith, finally, the side pad 9 expands under the filling of the oil, tightly fits the side edge of the equipment opening 8, and then tightly seals the side edge of the equipment opening 8, the gasket body 1 tightly seals the top edge of the equipment opening 8, the support strips 4 and the connecting strips 5 of the outer wall of the outer edge 2 and the inner edge 3 support the outer edge 2 and the inner edge 3, and improve the rigidity of the outer edge 2 and the inner edge 3 of the gasket body 1 under extrusion;

[0038] The rubber sealing gasket can tightly fit the top edge and the side edge of the equipment after being pressed, effectively improves the sealing effect, prevents various fluid leakage, and has strong pressure resistance, further improves the sealing effect and stability, and has high practicability.

[0039] Among them,

[0040] The gasket body 1, the outer ring edge 2 and the inner ring edge 3 are made of soft rubber material. During the installation of the gasket body 1 on the equipment cover plate and the subsequent sealing process of the equipment opening 8, the soft characteristics of the gasket body 1 can tightly fit the cover plate and the equipment opening 8, realizing the basic sealing function. When the top edge of the equipment opening 8 extrudes the pressure ring 6, the elastic rubber material of the pressure ring 6 is compressed, providing power for the flow of oil in the annular groove 7. The elastic rubber material of the side pad 9 will expand after the oil flows in. The expanded side pad 9 tightly fits the side edge of the equipment, further improving the sealing effect. The support bars 4 and the connecting bars 5 are made of hard rubber material. The support bars 4 stably support the outer ring edge 2 and the inner ring edge 3. The connecting bars 5 enhance the rigidity between the support bars 4, thereby improving the overall rigidity of the outer ring edge 2 and the inner ring edge 3, enhancing the pressure resistance of the gasket when being pressed, and ensuring the stability of the sealing process.

[0041] The opening 8 is arranged in an arc-shaped strip shape and has at least two symmetrical groups. The arc-shaped strip-shaped opening 8 provides a more smooth flow path for the oil. Compared with other shapes of openings 8, the oil flow rate is improved. The two symmetrical groups of openings 8 can make the oil flow uniformly and quickly from the annular groove 7 to the outer ring edge 2 and the side pad 9, so that the side pad 9 can quickly fill with oil and expand, tightly fit the side edge of the equipment in time, and efficiently realize the sealing function, improving the sealing efficiency and effect.

[0042] The inner part of the outer ring edge 2 is hollow and arranged in a ring shape. When the oil flows from the annular groove 7 into the outer ring edge 2 through the opening 8, the hollow structure of the ring provides sufficient and uniform storage space for the oil. After the oil enters the outer ring edge 2, it can quickly spread in the ring-shaped space, quickly guide the oil to the side pad 9, and make the side pad 9 quickly expand, tightly fit the side edge of the equipment, and improve the sealing effect, ensuring the timeliness and effectiveness of the equipment sealing.

[0043] At least two groups of connecting bars 5 are arranged between adjacent support bars 4, further improving the rigidity of the outer ring edge 2 and the inner ring edge 3. The rigid outer ring edge 2 and the inner ring edge 3 are not easy to deform when being pressed, always tightly fit the top edge of the equipment, effectively prevent fluid leakage caused by deformation of the gasket, ensure the stability of the sealing, and prolong the service life of the gasket.

[0044] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
