Abstract

The utility model discloses a sealing part. The sealing part comprises a body with a central hole, wherein circle center holes are further formed in two sides of the body, a radial convex body I and a radial convex body II are arranged at the upper portion and the lower portion of each of two sides of each circle center hole respectively, and the outer diameter of each radial convex body I is smaller than that of each radial convex body II. The sealing part is simple in structure, easy and convenient to manufacture, can effectively cooperate with a sealed objected to carry out sealing by arranging the radial convex bodies on the body, and improves the sealing effect.

Description

A kind of Sealing

Technical field

The utility model relates to a kind of Sealing.

Background technique

Sealing is to prevent fluid or material or the part of solid particle from leaking and prevent the component of the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane.Its Performance Influence Factor of various sealings is different, as mechanical seal (packing seal etc.) influence factor, temperature is arranged, medium, wearing and tearing, the pressure etc. that bears.

The model utility content

The utility model purpose is to provide a kind of rubber seal of simple in structure, good sealing effect.

Scheme of the present utility model is as follows: a kind of Sealing, comprise the body that is provided with center hole, described body two sides also are provided with circle center hole, and the upper and lower of described circle center hole two sides is respectively equipped with radially convex body I and radially convex body II, and the external diameter of described radially convex body I is less than radially convex body II.

The external diameter of described radially convex body I is 2mm, and radially the external diameter of convex body II is 5.5mm.

Described body is made by nitrile butadiene rubber or pvc material.

The beneficial effects of the utility model: simple in structure, preparation process is easy; By on body, arrange radially convex body effectively the fitted seal object seal, improve sealing effect.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.
