Abstract
The utility model relates to a sealing washer. The sealing washer comprises an annular washer body. A hollow hole is formed in the washer body. The upper side and the lower side of the cross section of the washer body are respectively provided with an arc-shaped protrusion. The left side and the right side of the cross section of the washer body are respectively provided with a concave groove. The concave grooves are semicircular grooves. The radius of each concave groove is one sixth of the overall height of the washer body. According to the sealing washer, due to the fact that the upper side and the lower side of the cross section are respectively provided with one arc-shaped protrusion, when a moment is applied, it is avoided that stress concentration causes ineffectiveness of the sealing washer, and the service life of the sealing washer is prolonged; due to the arrangement of the semicircular concave grooves, pressure is released during pressing, and damage is avoided.
Description
Technical field
The utility model relates to sealed product technical field, relates in particular to a kind of seal washer.
Background technique
Gasket seal be a kind of be exactly the sealing spare part of use for machinery, equipment, pipeline as long as there being the place of fluid, use inside and outside, the material sealing.Gasket seal is with metal or nonmetal tabular material, and through cutting, the techniques such as punching press or cutting are made, for being tightly connected between pipeline, and being tightly connected between the parts of machinery equipment and parts.Can be divided into metallic packing and nonmetal gasket seal by material.Metal have copper backing, stainless steel gasket, iron gasket, an aluminium backing etc.Nonmetallic have asbestos washer, non-asbestos washer, paper gasket, a rubber sheet gasket etc.
Now in machinery, the copper sealing washer between link mainly contains two kinds of conventional seals packing ring and composite-gaskets, the periphery of these two kinds of sealing gaskets is plane, making the surface of seal washer when by Sealing surface close contact by moment, can cause periphery stress to concentrate and cause the inefficacy of seal washer, reducing its working life.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of seal washer is provided.
The utility model is to be achieved through the following technical solutions:
A kind of seal washer, comprises annular packing ring body, on described packing ring body, has hollow hole, and the upper and lower both sides, cross section of described packing ring body are equipped with arc convex, and the left and right sides in the cross section of described packing ring body is equipped with Baltimore groove.
As optimal technical scheme of the present utility model, described arc convex and packing ring body adopt same material one-body molded.
As optimal technical scheme of the present utility model, described Baltimore groove is semi-circular groove, and its radius is 1/6th of packing ring body height.
As optimal technical scheme of the present utility model, the bearing of trend of described arc convex is vertical with packing ring body bearing of trend.
Described arc convex and metal washer body adopt same material one-body molded, are convenient to processing, easy to use.
Compared with prior art, the beneficial effects of the utility model are: the utility model, because upper and lower both sides arrange arc convex in cross section, in the time applying moment, avoids stress to concentrate the inefficacy that causes seal washer, improves its working life; By offering semicircle Baltimore groove, in the process of pressing, earth pressure release is gone out, avoid damaging.
