Abstract

The utility model provides a pair of novel sealing washer relates to sealing washer technical field, and hardness and tensile strength that have overcome current sealing washer can only be solved through changing the material, can not change its hardness and tensile strength's problem under the unchangeable condition of sealing washer volume, including the sealing washer, the sealing washer skin be equipped with the wearing layer, the wearing layer in be equipped with the skeleton, the wearing layer with the skeleton between still be equipped with the filling layer, the utility model discloses the product sets the sealing washer to wearing layer, filling layer and skeleton three-layer, has improved the hardness and the tensile strength of sealing washer, has improved the application range of this sealing washer.

Description

Novel sealing ring

Technical Field

The utility model belongs to the technical field of the sealing washer, in particular to novel sealing washer.

Background

In the market, the hardness and tensile strength of the existing sealing ring which needs to be adjusted can only be adjusted by replacing materials, the hardness and tensile strength of each type of rubber are determined, the hardness and tensile strength of the sealing ring made of the rubber are also determined, and the hardness and tensile strength of the sealing ring are changed under the condition that the volume of the sealing ring is not changed, which is a problem to be solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: a novel sealing ring is provided to solve the technical problems in the prior art.

According to the above-mentioned purpose, the basic technical scheme of the utility model is: the wear-resistant sealing ring comprises a sealing ring, wherein a wear-resistant layer is arranged on the outer layer of the sealing ring, a framework is arranged in the wear-resistant layer, and a filling layer is arranged between the wear-resistant layer and the framework;

furthermore, the sealing ring is of an annular structure, the upper part of the cross section of the sealing ring is a semicircle, and the lower part of the cross section of the sealing ring is a rectangle;

furthermore, the wear-resistant layer is made of one of nitrile rubber, polyurethane, cloth rubber and nylon;

further, the filling layer fills gaps among the frameworks;

furthermore, the material of the filling layer is natural rubber;

furthermore, the framework is in a closed ring shape and is formed by mutually winding and combining 2 or more than 2 wires;

furthermore, the wire is made of metal or fiber.

Compared with the prior art, the utility model discloses an advantage and beneficial effect:

1. the utility model has the advantages that the sealing ring is arranged into three layers of the wear-resistant layer, the filling layer and the framework, so that the hardness and the tensile strength of the sealing ring are improved;

2. the utility model discloses the product can be through the volume use proportion that changes wearing layer, filling layer and skeleton, can change the hardness and the tensile strength of novel sealing washer under the unchangeable condition of total volume, has improved the application range of this sealing washer.

Drawings

FIG. 1 is a schematic sectional view of the product of the present invention;

FIG. 2 is a schematic top view of the product of the present invention;

FIG. 3 is an enlarged schematic view of the structure at A in FIG. 1;

FIG. 4 is a schematic structural view of the product of the present invention when the skeleton is made of multiple strands of wire;

in the figure: 1. a seal ring; 2. a wear resistant layer; 3. a filling layer; 4. a framework; 5, 5 wire rods.

Detailed Description

Combine fig. 1 to 4, do the utility model discloses product embodiment structure schematic diagram, this novel sealing washer includes sealing washer 1, sealing washer 1 skin be equipped with wearing layer 2, wearing layer 2 in be equipped with skeleton 4, wearing layer 2 with skeleton 4 between still be equipped with filling layer 3, sealing washer 1 be the annular, its cross section upper portion is the semicircle, the cross section lower half is the rectangle, wearing layer 2's material be one of butadiene acrylonitrile rubber, polyurethane, double-layered cloth rubber and nylon, skeleton 4 between also be equipped with filling layer 3 in the gap, filling layer 3's material be natural rubber, combine fig. 4, skeleton 4 be closed annular form, form by the mutual winding combination of wire rod 5 more than 7 strands, wire rod 5's material be metal iron wire.

By wearing layer 2, the closed ring structure that filling layer 3 and skeleton 4 constitute, this structure can show tensile strength and the hardness that increases sealing washer 1, the hardness and the tensile strength of skeleton 4 all are stronger than wearing layer 2 and filling layer 3, under the unchangeable circumstances of overall volume, it is more when skeleton 4 accounts for than, wearing layer 2 and filling layer 3 account for less under the circumstances, 1 hardness of sealing washer and tensile strength are great, it is less when skeleton 4 accounts for than, wearing layer 2 and filling layer 3 account for more under the circumstances, 1 hardness of sealing washer and tensile strength are less, so under the unchangeable circumstances of overall volume, the utility model discloses the product can be through changing the wearing layer, the volume proportion of using of filling layer and skeleton, change the hardness and the tensile strength of novel sealing washer.

The particular embodiments described herein are illustrative only, as various modifications, additions and substitutions may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although used more herein: 1. a seal ring; 2. a wear layer; 3. a filling layer; 4. a framework; 5-wire, etc., without excluding the possibility of using other terms. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.

The above is to introduce the novel sealing ring provided by the present invention, and the principle and the implementation mode of the present invention are explained by applying the specific preferred embodiment in this introduction, and these embodiments are only used to help understanding the principle and the core idea of the present invention, it should be noted that, for those skilled in the art, the embodiments in the above embodiments can be further combined or replaced without departing from the design idea of the present invention, and a plurality of improvements and modifications can be made to the present invention, and these improvements and modifications also fall into the protection scope of the claims of the present invention.
