Description

Rubber sealing element for check valve

Technical Field

The utility model belongs to the technical field of sealing, and particularly relates to a rubber sealing element for a check valve.

Background

The main function of the check valve is to only allow the medium to flow in one direction, prevent the medium from reversing, or prevent the pump and the driving motor from reversing, and the discharge of the container medium, the check valve used on the engine oil filter of the automobile is installed in the filter, usually adopts a bowl-shaped or disc-shaped rubber diaphragm type design structure, and the bowl-shaped or disc-shaped rubber diaphragm type check valve is easy to open because of large bearing area, and the check fluid medium is sealed by the elasticity of rubber and the reverse oil pressure, so the adaptability is good, the matching of the compression amount can be not considered, the sealing effect can be achieved only by a certain compression amount, however, the rubber sealing element is difficult to meet the existing requirement in the use process, so the practicability is low, and the rubber sealing element for the check valve is provided for the user.

Disclosure of Invention

The present utility model is directed to a rubber seal for a check valve, which solves the problems set forth in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a rubber sealing member for check valve, includes the rubber circle body, the inside of rubber circle body is provided with interior pad, the outside of rubber circle body is provided with anticorrosive paint, one side of rubber circle body is provided with extends the pad, extend and be provided with the chamfer between pad and the rubber circle body.

As a preferable implementation mode, the anti-corrosion paint is sprayed on the outer part of the rubber ring body, and the anti-corrosion paint is made of butyl rubber anti-corrosion paint.

As a preferred embodiment, the inner pad is made of a material having a high friction coefficient.

As a preferred embodiment, the chamfer angle is between forty degrees and fifty degrees.

Compared with the prior art, the utility model has the beneficial effects that:

the rubber sealing piece for the check valve has the advantages that the body is wider, so that the rubber sealing piece can be tightly attached to an external valve core, the structure is compact, the rubber sealing piece can be combined with a labyrinth oil seal for use, meanwhile, the use effect is better, the sealing effect is better, and the rubber sealing piece is worthy of popularization and use;

this rubber sealing spare for check valve through setting up anticorrosive paint, can carry out anticorrosive to rubber sealing spare, avoids long-term corruption to make the problem that rubber sealing pad sealing effect became worse easily to the effectual life who improves rubber sealing pad.

Detailed Description

The utility model is further described below with reference to examples.

The following examples are illustrative of the present utility model but are not intended to limit the scope of the utility model. The conditions in the examples can be further adjusted according to specific conditions, and simple modifications of the method of the utility model under the premise of the conception of the utility model are all within the scope of the utility model as claimed.

Referring to fig. 1, 2 and 3, the utility model provides a rubber sealing member for a check valve, which comprises a rubber ring body 1, wherein an inner pad 3 is arranged in the rubber ring body 1, an anti-corrosion paint spraying 2 is arranged outside the rubber ring body 1, an extension pad 5 is arranged on one side of the rubber ring body 1, a chamfer 4 is arranged between the extension pad 5 and the rubber ring body 1, the anti-corrosion paint spraying 2 is sprayed outside the rubber ring body 1, the anti-corrosion paint spraying 2 is made of butyl rubber anti-corrosion paint, the inner pad 3 is made of a material with a larger friction coefficient, the angle of the chamfer 4 is between forty degrees and fifty degrees, the body is wider, so that the rubber sealing member can be tightly attached to an external valve core, and the rubber sealing member has a compact structure, can be combined with a labyrinth type oil seal for use, meanwhile, the use effect is better, the sealing effect is better, popularization and the problem that the sealing effect of the rubber sealing member is poor due to long-term corrosion can be avoided, and the service life of the rubber sealing member is effectively prolonged.

The working principle and the using flow of the utility model are as follows: firstly, the rubber ring body 1 body is wider, so that the rubber ring body can be tightly attached to an external valve core, and the structure is compact, the rubber ring body can be combined with a labyrinth oil seal for use, meanwhile, the use effect is better, the sealing effect is better, the rubber ring body is worth popularizing and using, the rubber sealing piece can be preserved by arranging the anti-corrosion paint 2, the problem that the sealing effect of the rubber sealing pad is poor due to long-term corrosion is avoided, and therefore the service life of the rubber sealing pad is effectively prolonged.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
