Abstract

The utility model discloses a metal wound gasket, which relates to a seal gasket which is an annular member which comprises metal straps and nonmetal straps, wherein the metal straps and the nonmetal straps are alternately arranged. The metal wound gasket is formed by mutually and alternately winding the metal straps and the nonmetal straps and is molded through pressure, therefore, the metal wound gasket not only has enough strength but also has good corrosion resistance and is not damaged in certain extreme media, and simultaneously, high expansion and contraction are not generated. The gasket has high plasticity and can adapt to the unevenness of a sealing surface after being compressed tightly to fill the gaps of the sealing surface so as to ensure that the metal wound gasket has good sealing property under the condition that system temperature and pressure are alternating.

Description

A kind of spiral wound gaskets
Technical field
The utility model relates to a kind of gasket seal, a kind of specifically high temperature resistant, high pressure and erosion-resisting spiral wound gaskets.
Background technique
At present, in the power station, aviation, petrochemical industry and valve seal field, the general pad of making by single rubber or asbestos material that adopts on the flange seal surface, because every field difference, the sealing medium difference, increasing occasion needs this kind pad to have high temperature resistant, high pressure and characteristics such as anticorrosive when causing using, and conventional pad then can't satisfy above-mentioned requirements, does not therefore have good sealing effect.
The model utility content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of spiral wound gaskets is provided, and it is simple in structure, and good sealing effect also has intensity height, high temperature resistant, high pressure and characteristics such as anticorrosive.
The utility model is the deficiency that solves the problems of the technologies described above, the technological scheme that is adopted is: a kind of spiral wound gaskets, the annular component that constitutes by metal tape and nonmetal band, metal tape and nonmetal tape alternation setting, the thickness of metal tape is 0.15-0.25mm, and the thickness of nonmetal band is 0.1-0.3mm.
The material of described metal tape is any one in stainless steel, carbon steel, nickel or the titanium.
The material of described nonmetal band is any one in graphite, teflon, asbestos or the pottery.
The beneficial effects of the utility model are:
1, the utility model alternately is entwined mutually by metal tape and nonmetal band, and, therefore enough intensity is arranged not only by pressure forming, also have good corrosion resistance, in some extreme media, do not destroyed, do not produce big expansion and contraction simultaneously by medium.
2, this pad has good plasticity, can adapt to the uneven of sealing surfaces after compressing and fills up the sealing surface gap, to guarantee having excellent sealing performance under the situation of system temperature and pressure alternation.
3, owing to the nonmetal band of the adjacent one deck of layer of metal band is entwined mutually, so this pad has good compression and rebound elasticity.
4, not softening, not creep under high temperature condition; Non-sclerous under the cryogenic conditions, do not shrink.
Description of drawings
Fig. 1 is a generalized section of the present utility model.
Mark among the figure: 1, metal tape, 2, nonmetal band.
Embodiment
As shown in Figure 1, a kind of spiral wound gaskets, by the metal tape 1 of multilayer with multilayer is nonmetal is with 2 to constitute, layer of metal band 1 adjacent one deck is nonmetal alternately to be twined and the annular component of formation with 2, compress welding and be integrative-structure thereafter, the innermost layer and the outermost surface of this pad are metal tape, and wherein the thickness of metal tape 1 is 0.15-0.25mm, and nonmetal thickness with 2 is 0.1-0.3mm.
The utility model is by the metal tape of " V " shape and nonmetally be with overlapped being entwined, and both should fit tightly, level is even, and the size of this pad is wherein the number of plies of metal tape and nonmetal band and can decides according to the size of valve sealing face.
Described metal tape 1 can be selected stainless steel, carbon steel, nickel or titanium for use, preferentially selects 300 series stainless steels in stainless steel for use, for example: 304,316,321 etc.
Describedly nonmetally be with 2 can select non-metallic materials such as graphite, teflon, asbestos, pottery for use.
The utility model is applicable to the sealing of various media, for example: steam, hydrogen, rock gas, cracking gas, oil product, acid, alkali, salt solution etc.
The utility model is entwined by metal tape and the nonmetal tape alternation of pre-molding, therefore have multiple-sealed, high temperature resistant, high pressure resistant, anticorrosive, to the advantage such as the flange seal surface roughness is less demanding, can be widely used in the industries such as power station, aviation, petrochemical industry, valve.
