Abstract

A laminated opening gasket seal comprises an obturating ring consisting of two laminated ferrules, and a cladding arranged on the upper surface and lower surface of the obturating ring, wherein, the inside tracks of the two laminated ferrules are separated from each other to form a gap, in which fillers are filled, and the filling density ranges from zero to ten gram per cubic centimeter. When the gasket seal is arranged between a pipeline and a flange, the pressure in the pipeline enters into the gap of the two ferrules. The pressure of medium is used to realize the self-strengthening effect of the gasket seal, to stabilize the sealing pressure and increase the ability of the soft gasket seal to be adaptive to the change in medium pressure and in the applied force on the sealing surface. In addition, the gap is filled with fillers and the adjustment of the compression ratio and resilient rate of sealing element is realized by controlling the density of fillers to meet different requirements of usage and to widen the range of application of gasket seal.

Description

Stacked opening sealing gasket
Technical field
The utility model relates to a kind of gasket seal, relates in particular to a kind of stacked gasket seal.
Background technique
In the prior art, gasket seal is many to make as materials such as asbestos, rubber, because the ability that this kind material meets with stresses is relatively poor, in use for some time, owing to bear the effect of pressure and ambient temperature, gasket seal is easily aging or lax, sealing variation even lose sealability, flexible when mounted distortion has simultaneously influenced sealing effect.The gasket seal that other has metallic material to make, limited because of the metallic material compression recovery performance, Applicable scope is narrower.
Summary of the invention
The utility model purpose provides a kind of stacked opening sealing gasket, and the bearing capacity of sealing pad is stronger.
The technical solution of the utility model is: a kind of stacked opening sealing gasket, it comprises by two the stacked seal rings that form of metal ring, the upper surface that is installed in the sealing circle and the coating on the lower surface, separately form the gap between the inner ring of described two stacked metal rings, be filled with packing in the described gap, the filling density of described packing is 0~10 gram/cubic centimetre.
Described two metal rings contact at the place, outer ring, and described two metal rings weld fixing on surface of contact.
Described coating protrudes from 0.1~10 millimeter on the surface of seal ring.
The utility model compared with prior art, has following advantage: when the installation of this gasket seal is applied between the piping flange, pressure in the pipeline can enter in two gaps between the metal ring, realize the self-strengthening of gasket seal to utilize pressure medium, stablize its seal pressure, improve the adaptive capacity of this flexible sealing gasket pressure medium variation and the variation of sealing surface external force.In addition, in the gap, insert packing,, realize the adjustment of gasket seal compression, rebound degree is reached different usage requirements, to enlarge the Applicable scope of gasket seal by control packing density.
Description of drawings
Accompanying drawing 1 is the plan view of gasket seal of the present utility model;
Accompanying drawing 2 is the sectional drawing at A-A place in the accompanying drawing 1;
Wherein: 1, metal ring; 2, coating; 3, gap; 4, packing; 5, seal ring.
Embodiment
Shown in Fig. 1-2, the utility model relates to a kind of stacked opening sealing gasket, it comprises by two metal rings, the 1 stacked seal ring that forms 5, the upper surface that is installed in sealing circle 5 and the coating on the lower surface 2, separately form gap 3 between the inner ring of described two stacked metal rings 1, the opening in gap 3 is facing to the inner ring inboard of metal ring 1.In embodiment commonly used of the present utility model, the material of described metal ring 1 can be one or more in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), the titanium.
The upper and lower surface of sealing pad is its sealing surface, and coating 2 promptly is on the sealing surface, and the material of described coating 2 is one or more the composite in graphite, fiber, teflon, the resin.When using installation, gasket seal is between the flange of butt joint pipeline, and coating 2 contacts with piping flange, plays the effect of seal action and protection seal ring, and this is common installation method, does not adopt accompanying drawing to give unnecessary details at this.When the sealing pad was installed application, the pressure in the pipeline can enter in the gap 3 through the opening in gap 3, utilizes pressure medium can realize the self-strengthening of gasket seal, stablizes its seal pressure.
Be filled with packing 4 in the described gap 3, can strengthen the bearing capacity of metal ring 1.Described packing 4 is one or more the composite in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium, graphite, fiber, teflon, the resin.Density by control packing 4, can realize adjustment to gasket seal compression, rebound degree, reach different usage requirements, in the preferred embodiment that the present invention adopts usually, the scope of the filling density of described packing 4 is controlled at 0~10 gram/cubic centimetre.
Described two metal rings 1 contact at outer ring place, and described two metal rings 1 on surface of contact, weld fixing, to form seal ring 5 structures that inner ring opening, outer ring seal.
See shown in Figure 2ly, described coating 2 is the protrusion form after covering on the surface of seal ring 5, and in embodiment commonly used of the present invention, the height that described coating 2 protrudes from seal ring 5 surfaces is controlled in 0.1~10 millimeter the scope usually.
The bearing capacity of above-described stacked opening sealing gasket is strong, and owing to the adjustment that can realize by the density of controlling packing 4 gasket seal compression, rebound degree, so can enlarge the application area of gasket seal.
