Abstract

The utility model belongs to the technical field of it is sealed, concretely relates to novel gasket. A main part (1) that's a novel gasket has spring (3) and the cladding is outside at the spring is proposed, main part (1) have two circular cone stage bodies that the longitudinal symmetry set up, and two circular cone stage bodies circular arc transition between, the upper and lower terminal surface of main part (1) is as the main part contact surface, the center of main part (1) has the axially extending bore that the internal diameter is the same of diameter and spring (3), main part (1) set up rubber sleeve circle (2) in the axially extending bore, rubber lasso (2) with main part (1) lock as an organic whole. The utility model provides an among the prior art gasket sealed not enough, elasticity not enough, uneven, the not locking problem of atress.

Description

A kind of Novel gasket

Technical field

The utility model belongs to technical field of sealing technology, is specifically related to a kind of Novel gasket.

Background technique

Pad is the mechanical seal between two objects, usually to prevent the pressurized between two objects from revealing, but now widely used pad, its performance such as elasticity, sealing does not often reach requirement, especially can not be locking, at some special dimensions, pad As time goes on the factors such as vibrations, contraction change, the sealing of pad and elasticity just seem particularly not enough, and then can affect working efficiency.

Model utility content

For the sealing solving prior art Intermediate gasket is inadequate, elasticity is not enough, unbalance stress, the problem such as not locking, the purpose of this utility model proposes a kind of Novel gasket.

The utility model adopts following technological scheme for completing above-mentioned purpose;

A kind of Novel gasket, described pad has spring and is coated on the main body of spring outside; Described main body has symmetrically arranged two circular cone stage bodies up and down, and arc transition between two circular cone stage bodies; The center of described main body has the diameter axial hole identical with the internal diameter of spring; Be provided with rubbery loop in the described axial hole of main body, described rubbery loop and described main body fasten and are integrated.

The outer wall of described rubbery loop has the annular protrusion for being fastened and connected with main body.

A kind of Novel gasket that the utility model proposes, arc transition is adopted to connect between upper and lower two the circular cone stage bodies of main body of pad, alleviate the stress that pad produces due to compression to concentrate, rubbery loop is placed in pad, the movement of built-in spring can be stopped on the one hand, can seal action be played on the other hand; Spring is in pre-pressing state in gasket body inside, in the process of pad pressure, surface of contact uniform force can be made to concentrate, and then also can reach locking effect, the sealing solving prior art Intermediate gasket is inadequate, elasticity is not enough, unbalance stress, not locking problem.

Fig. 2 is assembling schematic diagram of the present utility model.

Fig. 3 is sectional view of the present utility model.

In figure: 1, main body, 2, rubbery loop, 3, spring.

Embodiment

With specific embodiment, the utility model is further described by reference to the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Novel gasket, described pad has spring 3 and is coated on the main body 1 of spring outside; Described main body 1 has symmetrically arranged two circular cone stage bodies up and down, and arc transition between two circular cone stage bodies, and can alleviate the stress that pad produces due to compression and concentrate, the upper and lower end face of main body 1 is as body contact face; The center of described main body 1 has the diameter axial hole identical with the internal diameter of spring 3; Be provided with rubbery loop 2 in the described axial hole of main body 1, described rubbery loop 2 fastens with described main body 1 and is integrated; Described rubbery loop 2 one aspect can stop the movement of spring, and can play seal action on the other hand, described spring, in the process of pad pressure, can make surface of contact 12 uniform force concentrate, and then also can reach locking effect.

The outer wall of described rubbery loop 2 has the annular protrusion for being fastened and connected with main body.

Claims

1. a Novel gasket, is characterized in that: described pad has spring (3) and is coated on the main body (1) of spring outside; Described main body (1) has symmetrically arranged two circular cone stage bodies up and down, and arc transition between two circular cone stage bodies; The upper and lower end face of main body (1) is as body contact face; The center of described main body (1) has the diameter axial hole identical with the internal diameter of spring (3); Be provided with rubbery loop (2) in the described axial hole of main body (1), described rubbery loop (2) and described main body (1) fasten and are integrated.
