Abstract

The utility model relates to a novel rubber seal, include: first outer lane, spacing collar and second outer lane, the spacing collar cover is established in the first outer lane outside, the one end of first outer lane is equipped with the draw-in groove, the second outer lane cover is established in the draw-in groove, the one side of spacing collar and the one side of second outer lane are the wainscot structure, the outside of first outer lane, and the one end of keeping away from the second outer lane is the conical surface structure, the one side that the second outer lane and spacing collar pasted mutually, and the outside of spacing collar is concave surface structure, and the good life-span that uses of the sealing washer of rubber material is not only good, can let sealing performance become better through the extrusion sealing washer, can reduce the leakage better when using as static seal. When the reciprocating valve is used for reciprocating motion, the sealing performance is unchanged in the reciprocating motion, the leakage is reduced, the structure is simple, and the effect is obvious.

Description

Novel rubber sealing element

Technical Field

The utility model relates to a rubber seal, in particular to novel rubber seal.

Background

The rubber sealing element is a general basic element in the sealing device, plays an important role in the contradiction of leakage and sealing, solves the leakage and sealing problems in the process of conquering nature by human, always promotes the technical progress, and is an important way for preventing and reducing environmental pollution.

The traditional rubber sealing element has poor sealing performance, the phenomenon of leakage is easy to occur under the condition that the rubber sealing element is cracked, and a great deal of inconvenience is brought to the life of people.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the novel rubber sealing element is beneficial to improving the sealing performance of the rubber sealing element so that the leakage is not easy to occur.

A novel rubber seal, comprising: the outer side of the first outer ring is sleeved with the limiting ring, a clamping groove is formed in one end of the first outer ring, the second outer ring is sleeved in the clamping groove, one surface of the limiting ring and one surface of the second outer ring are of a face pasting structure, the outer side of the first outer ring and one end, far away from the second outer ring, of the first outer ring are of a conical surface structure, the face, pasted with the limiting ring, of the second outer ring, and the outer side of the limiting ring is of a concave surface structure.

Further, the first outer ring, the limiting ring and the second outer ring are coaxial.

Furthermore, the width of the second outer ring is larger than that of the limiting ring.

The utility model has the advantages that: the rubber sealing ring is good in elasticity and long in service life, sealing performance can be better by extruding the sealing ring, and leakage can be better reduced when the rubber sealing ring is used for static sealing. When the reciprocating valve is used for reciprocating motion, the sealing performance is unchanged in the reciprocating motion, the leakage is reduced, the structure is simple, and the effect is obvious.

Detailed Description

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A novel rubber seal, comprising: first outer lane 1, spacing collar 2 and second outer lane 3, 2 covers of spacing collar are established in the 1 outside of first outer lane, the one end of first outer lane 1 is equipped with draw-in groove 4, 3 covers of second outer lane are established in draw-in groove 4, the one side of spacing collar 2 is the wainscot structure with the one side of second outer lane 3, the outside of first outer lane 1, and the one end of keeping away from second outer lane 3 is the conical surface structure, the one side that second outer lane 3 pasted mutually with spacing collar 2, and the outside of spacing collar 2 is the concave surface structure.

The first outer ring 1, the limiting ring 2 and the second outer ring 3 are coaxial.

The width of the second outer ring 3 is larger than that of the spacing ring 2.

The utility model discloses concrete theory of operation is: the extrusion through 1 spacing collar 2 in first outer lane and second outer lane 3 is sealed, and the 1 outside in first outer lane just keeps away from the conical surface structure of the one end of second outer lane 3, and the one side that second outer lane 3 and spacing collar 2 pasted mutually, and the concave surface structure in the outside of spacing collar 2 has all increased the leakproofness.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims (3)
