Description

Technical Field

[0001] The utility model relates to the technical field of sealing components, and more specifically, to a sealing component capable of self-adapting pressure regulation. Background Art

[0002] Seals are an important component widely used in the engineering field. Their main function is to fill or block the gaps between equipment and components in various mechanical equipment and devices, prevent the leakage of fluids or gases, and prevent the entry of external impurities.

[0003] Traditional seals have the following shortcomings: Traditional seals often need to work under high or low pressure during use. Under high pressure, the inside of the seal will swell and harden, and may not be able to seal after a long time. Under low pressure, seals may be deformed or damaged due to lack of necessary support and protection when used in a low pressure environment for a long time, resulting in detachment and inability to activate the sealing function. Therefore, they need to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a sealing element with adaptive pressure regulation, which has the advantage of adaptive pressure regulation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adaptive pressure regulating seal, comprising a seal, wherein airbags are fixedly mounted on the upper and lower sides of the seal, folds are arranged on the outer side of the airbag, and an air groove is opened inside the airbag.

[0006] As a preferred technical solution of the utility model, arc-shaped grooves close to the inner surface of the seal are uniformly opened inside the seal, and the arc surface of the arc-shaped grooves corresponds to the arc surface of the seal.

[0007] As a preferred technical solution of the utility model, grooves are evenly formed on the outer surface of the seal, and elastic convex rings located on both sides of the grooves are fixedly mounted on the outer surface of the seal.

[0008] As a preferred technical solution of the utility model, the airbag is made of rubber, and the folds are evenly distributed on the outer surface of the airbag in a vertical direction.

[0009] As a preferred technical solution of the utility model, the number of the grooves is three and they are evenly distributed on the outer surface of the seal in a vertical direction, and the grooves are a "U"-shaped structure in cross section.

[0010] As a preferred technical solution of the utility model, the arc-shaped groove is a "mouth"-shaped structure in cross section, and the number of the arc-shaped grooves is five and they are evenly distributed inside the seal in the vertical direction.

[0011] As a preferred technical solution of the utility model, the arc surface of the outer surface of the elastic convex ring is a "semi-circular" structure, and the arc surface of the upper surface of the elastic convex ring corresponds to the arc surface of the sealing member.

[0012] As a preferred technical solution of the utility model, the sealing member is made of rubber, and the sealing member has an "O"-shaped structure in cross section.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model seals the seal by installing it between two joints. Under high-pressure environment, the high pressure on the outside of the seal is relieved by the arc groove. Compared with traditional seals, the adaptive pressure-adjusting seal achieves the effect of relieving high pressure by opening an arc groove inside the seal, thereby improving the practicality of the seal.

[0015] 2. The utility model installs an airbag on the outside of the seal. When the pressure of the gas in the air groove decreases, the gas in the air groove expands and the folds are stretched, thereby sealing the joints. Compared with traditional seals, this adaptive pressure-adjustable seal installs an airbag on the outer surface of the seal so that it can still provide good sealing performance in a low-pressure environment, thereby improving the practicality of the seal.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides a seal with adaptive pressure regulation, including a seal 1, air bags 2 are fixedly mounted on both upper and lower sides of the seal 1, folds 5 are arranged on the outer side of the air bag 2, and an air groove 6 is opened inside the air bag 2.

[0024] The seal 1 is placed between the two joints and a certain pressure is applied to create a close contact between the seal 1 and the joints, thereby sealing them. Under high pressure, the seal 1 expands, causing the arc groove 3 to slowly shrink due to the expansion force, so that the seal 1 preferentially expands toward the inside of the arc groove 3, thereby relieving the pressure outside the seal 1. When the pressure returns to normal, the arc groove 3 drives the seal 1 to release elastic potential energy and return to its original state.

[0025] The seal 1 is installed between two joints to seal them. Under high-pressure conditions, the high pressure on the outside of the seal 1 is relieved by the arc groove 3. Compared with traditional seals, this adaptive pressure-regulating seal achieves the effect of relieving high pressure by opening the arc groove 3 inside the seal 1, thereby improving the practicability of the seal.

[0026] The seal 1 is evenly provided with arc-shaped grooves 3 close to the inner surface of the seal 1 , and the arc surface of the arc-shaped grooves 3 corresponds to the arc surface of the seal 1 .

[0027] In a low-pressure environment, when the pressure of the gas in the gas groove 6 decreases, the interaction force between molecules is weakened, which increases the distance between gas molecules, thereby causing the gas volume to increase, causing the gas in the gas groove 6 to expand, exerting an expansion force on the folds 5, causing the folds 5 to stretch, thereby sealing the joints.

[0028] By installing the airbag 2 on the outside of the seal 1, when the pressure of the gas in the air groove 6 decreases, the gas in the air groove 6 expands and the folds 5 are stretched, thereby sealing the joints. Compared with traditional seals, this adaptive pressure-adjustable seal installs the airbag 2 on the outer surface of the seal 1 so that it can still provide good sealing performance in a low-pressure environment, thereby improving the practicability of the seal.

[0029] The outer surface of the sealing member 1 is evenly provided with grooves 4 , and the outer surface of the sealing member 1 is fixedly provided with elastic convex rings 7 located on both sides of the grooves 4 .

[0030] By providing a groove 4 on the outer surface of the seal 1 , the friction force at the position in close contact with the external shell is reduced, making it easier to disassemble and maintain the seal 1 .

[0031] The airbag 2 is made of rubber, and the wrinkles 5 are evenly distributed on the outer surface of the airbag 2 in a vertical direction.

[0032] Rubber has excellent elasticity and wear resistance, and also has good anti-oxidation, acid and alkali corrosion resistance and other properties, so that the airbag 2 is suitable for various environments.

[0033] There are three grooves 4 which are evenly distributed on the outer surface of the seal 1 in a vertical direction, and the grooves 4 are of a "U"-shaped structure in cross section.

[0034] A groove 4 is provided on the outer surface of the seal 1 to prevent the seal 1 from being completely closely attached to the outer shell.

[0035] The arc groove 3 has a "mouth"-shaped structure in cross section, and there are five arc grooves 3 which are evenly distributed inside the seal 1 in a vertical direction.

[0036] Under high pressure, the seal 1 expands, causing the arc groove 3 to shrink slowly due to the expansion force, so that the seal 1 expands preferentially toward the inside of the arc groove 3 , thereby relieving the pressure outside the seal 1 .

[0037] The arc surface of the outer surface of the elastic convex ring 7 is a "semi-circular" structure, and the arc surface of the upper surface of the elastic convex ring 7 corresponds to the arc surface of the sealing member 1.

[0038] The outer surface of the elastic convex ring 7 is a "semi-circular" structure, thereby greatly reducing the area in close contact with the external shell.

[0039] The sealing member 1 is made of rubber, and has an "O"-shaped structure in cross section.

[0040] Rubber has excellent elasticity and wear resistance, and also has good anti-oxidation, acid and alkali corrosion resistance and other properties, so that the sealing element 1 is suitable for various environments.

[0041] The working principle and use process of this utility model:

[0042] The seal 1 is placed between the two joints and a certain pressure is applied to create a close contact between the seal 1 and the joints, thereby sealing them. Under high pressure, the seal 1 expands, causing the arc groove 3 to slowly shrink due to the expansion force, so that the seal 1 preferentially expands toward the inside of the arc groove 3, thereby relieving the pressure outside the seal 1. When the pressure returns to normal, the arc groove 3 drives the seal 1 to release elastic potential energy and return to its original state.

[0043] In a low-pressure environment, when the pressure of the gas in the gas groove 6 decreases, the interaction force between molecules is weakened, which increases the distance between gas molecules, thereby causing the gas volume to increase, causing the gas in the gas groove 6 to expand, exerting an expansion force on the folds 5, causing the folds 5 to stretch, thereby sealing the joints.
