Abstract

The utility model relates to a novel gasket, in particular to a gasket used on machinery equipment. Existing gaskets are generally short in service life and poor in waterproofness, airtightness and other performance. The novel gasket comprises a two-layer circular hollow gasket body, wherein the lower layer of the gasket body is made of metal, and a silica gel layer is attached to the upper layer of the gasket body, so that elasticity is enhanced, the sealing property is good, and friction is reduced; since the gasket body is evenly provided with six small through holes, materials are saved, the weight of the gasket is reduced, and the functions of the gasket are not affected; the outer edge of the gasket body is evenly provided with six through grooves, so that concentrated stress is relieved, and the service life of the gasket is prolonged; the inner edge of the gasket body is sleeved with a plastic ferrule, so that the sealing property is enhanced, the friction is relieved, and abrasion is reduced. The novel gasket is simple in structure, capable of saving materials, low in price, good in waterproofness and sealing property, and long in service life.

Description

A kind of Novel gasket

technical field

The utility model relates to a kind of Novel gasket, particularly a kind of for the pad in machinery equipment.

Background technique

Now widely used pad is all a kind of material, and the performances such as elasticity, water proofing property and sealing are all poor, and pressure is very concentrated, and fretting wear is larger, causes using the pad life-span greatly to shorten.The flange connections such as valve, pump, heat exchanger are very high to sealing requirements, slightly reveal and just likely cause serious consequence, and be difficult for often changing.Pad part is less, is difficult for processing, so simple in structure for well.Following equipment is more and more higher to the requirement of pad, therefore, adapts to development in science and technology, and equipment needs, and innovates a kind of simple in structurely, saves material, cheap, waterproof, good seal performance, and working life, longer pad seemed particularly important.

Summary of the invention

The utility model provides a kind of Novel gasket, for adapting to the performance requirement of following equipment to pad, for the defect of existing pad, revises, and has improved the various aspects of performance of pad.

The utility model comprises shim body, groove, through hole, plastic ferrule and layer of silica gel.Shim body is a two-layer circular hollow pad, and lower floor's pad is metal material, and upper strata is with one deck silica gel, and thickness is approximately 1-2mm; In shim body, evenly have six small through hole, save material, increase Economy; Shim body outward edge is evenly offered six grooves, and groove is semicircle; Pad inward flange cover has one deck plastic ferrule.

Shim body is circular hollow, and is divided into two-layer up and down.

Lower floor's pad is nickel steel material, and upper strata pad is silica gel.

On pad, evenly offer six through holes.

Shim body outward edge is evenly offered six semicircle grooves.

Pad inward flange cover has one deck plastic ferrule.

Advantage: shim body is circular hollow, and offer through hole, both saved material, reduce costs, can alleviate quality again; Silica gel and inward flange lasso have reduced frictional loss; Outward edge groove has discharged concentrated stress, has extended the working life of pad; Pad overall structure is simple, cheap.

Accompanying drawing explanation

Accompanying drawing 1 is the plan view of structural representation of the present utility model.

Accompanying drawing 2 is plan views of structural representation of the present utility model.

In accompanying drawing: 1. shim body; 2. groove; 3. through hole; 4. inward flange lasso; 5. layer of silica gel;

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.As shown in the figure, the utility model comprises circular hollow shim body 1, shim body 1 is containing two-layer up and down, lower floor is metal material pad, wherein metal is nickel steel, upper strata is silica gel thin-layer 5, reduce frictional loss, and enhanced leaktightness performance, in shim body 1, around the center of circle, evenly offer six through holes 3, further reduce costs, alleviate pad quality, shim body 1 outward edge is evenly provided with six grooves 2, alleviating extrusion stress concentrates, extend the working life of pad, pad inward flange cover has a plastic ferrule 4, further reduce friction, protection equipment, and can strengthen sealability.In a word, the utility model, simple in structure, save material, cheap, waterproof, good seal performance, working life is longer.
