Abstract

The utility model discloses a novel profile of tooth gasket, including the gasket body, the gasket body includes support ring and sealing ring, the sealing ring has two and sets up two terminal surfaces about the support ring respectively, support ring and sealing ring all are cyclic annular and the size is the same, the sealing ring includes graphite ring and mica ring, the mica ring has two and sets up respectively in the inside and outside both sides of graphite ring, this utility model discloses rational in infrastructure, this gasket is through setting up the mica ring in the both sides of graphite ring, and graphite uses with mica's combination, has both solved the poor problem of mica leakproofness, utilizes mica's high temperature resistance and oxidation resistance simultaneously again, can prevent effectively that this gasket from when using under high temperature, and graphite on the sealing ring is to both sides diffusion under high temperature to influence the sealed effect of this gasket.

Description

Novel tooth-shaped gasket

Technical Field

The utility model relates to a sealed technical field, in particular to novel profile of tooth gasket.

Background

In life, most places need to use a sealing gasket, and the sealing gasket is used for preventing fluid or solid particles from leaking between adjacent joint surfaces and preventing external impurities such as dust, moisture and the like from invading materials or parts of parts inside machine equipment. The sealing gasket through groove in the prior art adopts the graphite gasket to seal the flange, but because the heat resistance of graphite is relatively poor, the diffusion takes place easily when using under high temperature to lead to when the high temperature state is using, the leakproofness of graphite gasket is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel profile of tooth gasket.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a novel profile of tooth gasket, includes the gasket body, the gasket body includes support ring and sealing ring, the sealing ring has two and sets up two terminal surfaces about the support ring respectively, support ring and sealing ring all are cyclic annular and the size is the same, the sealing ring includes graphite ring and mica ring, mica ring has two and sets up the inside and outside both sides at the graphite ring respectively.

Preferably, the sealing ring is provided with a tooth groove which is annular, and the sealing ring is provided with a ring strip matched with the tooth groove.

Preferably, the support ring is a stainless steel ring or other metal ring.

Preferably, the graphite ring and the mica ring are concentric rings and are positioned on the same horizontal plane.

The utility model has the advantages that: the mica rings are arranged on the two sides of the graphite ring, and the graphite and the mica are combined for use, so that the problem of poor sealing performance of the mica is solved, and meanwhile, the high temperature resistance and the oxidation resistance of the mica are utilized, and the graphite on the sealing ring is effectively prevented from diffusing to the two sides at high temperature when the gasket is used at high temperature, so that the sealing effect of the gasket is influenced.

Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 and 2, a novel tooth-shaped gasket, including gasket body 1, gasket body 1 includes support ring 11 and sealing ring 12, support ring 11 is stainless steel ring or other metal ring, sealing ring 12 has two and sets up respectively in two terminal surfaces about support ring 11, wherein, tooth's socket 2 has been seted up on sealing ring 12, tooth's socket 2 is cyclic annularly, be provided with on the sealing ring 12 with tooth's socket 2 assorted holding ring 3, so set up, can increase the area of contact between sealing ring 12 and the support ring 11, make two rings when being compressed tightly by the pressure equipment, the installation between sealing ring 12 and the support ring 11 is more firm.

Support ring 11 and sealing ring 12 all are cyclic annular and the size is the same, and sealing ring 12 includes graphite ring 121 and mica ring 122, and graphite ring 121 and mica ring 122 are the concentric ring and are located same horizontal plane, and mica ring 122 has two and sets up the inside and outside both sides at graphite ring 121 respectively.

According to the gasket, the mica rings 122 are arranged on two sides of the graphite ring 121, and graphite and mica are combined for use, so that the problem of poor sealing performance of mica is solved, and meanwhile, the high temperature resistance and the oxidation resistance of mica are utilized, so that the graphite on the sealing ring 12 can be effectively prevented from diffusing to two sides at high temperature when the gasket is used at high temperature, and the sealing effect of the gasket is influenced.
