Description
Technical Field
The utility model relates to a technical field of gasket particularly, relates to a corrosion-resistant gasket.
Background
Gaskets are materials made of paper, rubber or copper sheets, placed between two planes to enhance sealing, and are mechanical seals between two objects to prevent fluid leakage, typically to prevent pressure, corrosion, and natural expansion and contraction of the tubing between the two objects. Since the machined surface may not be perfect, irregularities can be filled using shims, which are typically made of sheet material, such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers such as polytetrafluoroethylene.
The electric field uses the gasket mostly, but usually adopt metal gasket or field preparation plane gasket or bakelite gasket, these gaskets although can use, have insulating nature poor, the not corrosion-resistant shortcoming, especially when insulating properties is poor, cause equipment puncture or even electricity easily, the incident appears in the ease, influences the safe operation of power equipment.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem among the correlation technique, the utility model provides a corrosion-resistant gasket wholly has good insulation and corrosion resisting capability.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the utility model provides a corrosion-resistant gasket, includes the gasket body that adopts the PA material to make, the middle part of gasket body bulge upwards forms the lug portion, the through-hole has been seted up at the middle part of lug portion, the surface cladding of gasket body has the polytetrafluoroethylene membrane.
Further, the thickness of gasket body is 3 mm.
Further, the gasket body is fixedly connected with the polytetrafluoroethylene film through an adhesive layer.
Further, the section of the lug part is arc-shaped.
The utility model has the advantages that: the whole body has good insulating and corrosion resisting capabilities, long service life and low cost, and is worthy of popularization.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a cross-sectional view of a corrosion resistant gasket in accordance with an embodiment of the present invention.
In the figure:
1. a gasket body; 2. a tab portion; 3. a through hole; 4. a polytetrafluoroethylene membrane.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, according to the embodiment of the present invention, a corrosion-resistant gasket comprises a gasket body 1 made of PA material, a convex drum is formed at the middle part of the gasket body 1 upward to form a convex portion 2, a through hole 3 is opened at the middle part of the convex portion 2, and a teflon film 4 is wrapped on the surface of the gasket body 1.
In a specific embodiment of the present invention, the thickness of the gasket body 1 is 3 mm.
In a specific embodiment of the present invention, the gasket body 1 is fixedly connected to the ptfe film 4 through an adhesive layer.
In a specific embodiment of the present invention, the cross-section of the protruding portion 2 is arc-shaped.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
The corrosion-resistant gasket of the utility model comprises a gasket body 1 and a polytetrafluoroethylene membrane 4.
Gasket body 1 includes the lug portion 2 at middle part and the flat portion at edge, and lug portion 2 bulge drum up is used for producing elastic stress, and the cross-section of lug portion 2 forms and is the arc, and through-hole 3 has been seted up to its middle part, and gasket body 1 adopts the PA material to make, and the thickness of gasket is 3mm, and the PA material gasket is strong to the absorptive capacity of impact, stress vibration, can form fine cushioning effect.
The polytetrafluoroethylene film 4 is bonded on the surface of the gasket body 1 through glue, and the polytetrafluoroethylene film 4 has an excellent corrosion resistance effect.
When the gasket is used specifically, the gasket body 1 is provided with the lug part 2, and when the gasket body is pressed tightly, the lug part 2 moves downwards to generate elastic stress, so that the gasket body 1 is fastened with the connecting piece to prevent loosening and falling; the polytetrafluoroethylene film 4 is arranged, so that the gasket has good insulating property and corrosion resistance, and is not rusted or electrically broken in use.
To sum up, with the help of the utility model discloses an above-mentioned technical scheme wholly has good insulating and corrosion-resistant ability, long service life, and is with low costs, is worth promoting.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
