Abstract

The utility model discloses a sealing gasket for a controller of an electric compressor, which comprises a body, wherein the body is composed of stainless steel plates embedded in a rubber layer, limiting holes are arranged at four corners of the body, the inner edge and the outer edge of the body are respectively provided with a closed sealing bulge, the sealing bulges and the rubber layer are integrally formed, and the vertical cross sections of the stainless steel plates and the rubber layer are oval; this oval-shaped corrosion resistant plate of patent and rubber layer receive ascending extrusion of horizontal direction, receive under the extruded condition, its structure has the elasticity of reconversion, so can make and form a sealed cell body between rubber layer surface and the adjacent sealed arch, a cell body has been formed again between two sealed archs, thereby can realize on the one hand that it has two sealed cell bodies, sealing performance greatly reduced, and oval-shaped corrosion resistant plate and rubber layer can make and increase along with the time of using, its sealing performance also can not reduce, thereby keep high leakproofness all the time.

Description

Sealing gasket for controller of electric compressor

Technical Field

The utility model relates to a sealed pad field, more specifically say, relate to a sealed pad of electric compressor controller.

Background

The compressor is a driven fluid machine for raising low-pressure gas into high-pressure gas, and the sealing gasket is one of indispensable components in the compressor, however, as the service life increases, the sealing performance of the sealing gasket is gradually reduced due to dislocation or self deformation of the sealing gasket.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved

To the problem that the sealing performance of the sealed pad that exists can reduce gradually among the prior art, the utility model aims to provide a sealed pad of motor compressor controller, it can realize sealed high leakproofness of filling up.

2. Technical scheme

In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a sealed pad of motor compressor controller, includes the body, the body constitute by the embedded corrosion resistant plate in rubber layer, body four corners department is provided with spacing hole, the inner edge and the outer fringe of body respectively set up a closed sealed arch, sealed arch and rubber layer integrated into one piece, the vertical cross-section on corrosion resistant plate and rubber layer be oval.

Preferably, the rubber layer is made of nitrile rubber.

Preferably, the middle part of the oval shape is provided with a nitrile rubber ball.

Preferably, a groove is formed in the body between the two sealing bulges, the groove is communicated with the limiting hole, and one end of the spring is fixedly connected in the groove.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages of: this oval-shaped corrosion resistant plate of patent and rubber layer receive ascending extrusion of horizontal direction, receive under the extruded condition, its structure has the elasticity of reconversion, so can make and form a sealed cell body between rubber layer surface and the adjacent sealed arch, a cell body has been formed again between two sealed archs, thereby can realize on the one hand that it has two sealed cell bodies, sealing performance greatly reduced, and oval-shaped corrosion resistant plate and rubber layer can make and increase along with the time of using, its sealing performance also can not reduce, thereby keep high leakproofness all the time.

Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

Example 1:

referring to fig. 1-4, a sealing gasket for a controller of an electric compressor comprises a body 1, wherein the body 1 is composed of a stainless steel plate 3 embedded in a rubber layer 2, limiting holes 4 are formed in four corners of the body 1, a closed sealing bulge 5 is respectively arranged on the inner edge and the outer edge of the body 1, the sealing bulge 5 and the rubber layer 2 are integrally formed, and the vertical cross sections of the stainless steel plate 3 and the rubber layer 2 are elliptical. The rubber layer 2 is made of nitrile rubber.

As shown in fig. 3, when the sealing gasket is installed, the oval stainless steel plate 3 and the rubber layer 2 are horizontally extruded, and under the condition of extrusion, the structure of the sealing gasket has elastic force capable of restoring to the original state, so that a sealed groove body can be formed between the outer surface of the rubber layer 2 and the adjacent sealing bulges 5, and a groove body is formed between the two sealing bulges 5, so that the sealing gasket can be provided with two sealed groove bodies, the sealing performance is greatly reduced, the oval stainless steel plate 3 and the rubber layer 2 can increase along with the use time, the sealing performance cannot be reduced, and the high sealing performance is always kept.

Example 2:

the middle part of the ellipse is provided with a nitrile rubber ball 6.

The nitrile rubber ball 6 can ensure that the stainless steel plate 3 and the rubber layer 2 not only have certain elasticity through self (oval) under the condition of extrusion, but also generate certain elasticity through the nitrile rubber ball 6, so that the nitrile rubber ball can keep high sealing performance.

Example 3:

a groove 7 is formed in the body 1 between the two sealing bulges 5, the groove 7 is communicated with the limiting hole 4, and one end of a spring 8 is fixedly connected in the groove 7.

In the long-time in-process of using of body, can become flexible gradually through the fixed screw of spacing hole of screw run through, and this patent passes through the spring, makes the screw through spacing fixed body of hole can be long-time keep its fastness to guarantee the long-time normal work of body.

The above; is only a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; according to the technical scheme of the utility model and the improvement conception, equivalent substitution or change is carried out; are all covered by the protection scope of the utility model.
