Abstract
The utility model relates to a semi-arc gasket seal, comprising a ferrule with a U-shaped longitudinal section, and a cladding arranged on the upper surface and lower surface of the ferrule, wherein, the ferrule has a gap, in which hard fillers are filled, and the filling density ranges from zero to ten gram per cubic centimeter. Because the ferrule is pressed into the structure of the U-shaped longitudinal section and the U-shaped gap is filled with fillers with adjustable filling density, the adjustment of the compression ratio and resilient rate of sealing element is realized by controlling the density of fillers, which increases the anti-pressure ability of gasket seal and improves the sealing effect.
Description
Technical field
The utility model relates to a kind of gasket seal.
Background technique
In the prior art, gasket seal is many to be made with 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 is that the semiarc sealing gasket that a kind of adjustable seamless contracts, thereby rebound degree strengthens anti-pressure ability is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of semiarc sealing gasket, it comprises metal ring, the upper surface that is installed in described metal ring and the coating on the lower surface that the longitudinal section takes the shape of the letter U, described metal ring has the gap, in described gap, be filled with the hard packing, and the filling density of described packing is less than 10 gram/cubic centimetres greater than 0 gram/cubic centimetre.
Also be installed with limit collar on the outer ring of described metal ring.
Described coating protrudes from 0.1～10 millimeter on the surface of metal tube.
Because technique scheme utilization, the utility model compared with prior art has following advantage: because the metal ring compacting is the structure that the longitudinal section is a U-shaped, in the gap of this U-shaped, fill packing, the adjustable density of its filling is whole, thereby can be by the density of control packing, realize adjustment, strengthened the anti-pressure ability of pad greatly, play better sealing effect Sealing compression, rebound degree.
Description of drawings
Accompanying drawing 1 is the plan view of gasket seal of the present utility model;
Accompanying drawing 2 is the amplification profile at A-A place in the accompanying drawing 1;
Wherein: 1, metal ring; 2, coating; 3, gap; 4, packing; 5, limit collar.
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
Semiarc sealing gasket as depicted in figs. 1 and 2, it comprises metal ring 1, the longitudinal section of this metal ring 1 takes the shape of the letter U, because taking the shape of the letter U, it is provided with so have gap 3, in gap 3, be filled with packing 4, this packing 4 is a carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium, graphite, fiber, teflon, the composite of one or more in the resin, and the density of filling can be regulated in the scope of 0～10 gram/cubic centimetre, thereby density by control packing 4, can realize Sealing is compressed, the adjustment of rebound degree is to reach different application targets.
On the upper surface of metal ring 1 and lower surface, be installed with coating 2; and coating 2 protrudes from 0.1～10 millimeter on metal ring 1 surface; the material of this coating 2 can be selected one or more the composite in graphite, fiber, teflon, the resin for use; 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 metal ring; this is common installation method, no longer gives unnecessary details with accompanying drawing at this.
Rigidity for the enhanced leaktightness pad, also be installed with limit collar 5 on the outer ring of described metal ring 1, the material of this limit collar 5 is a kind of in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), the titanium, can stop metal ring 1 lateral deformation by limit collar 5 is set.
When being installed in the sealing pad between the piping flange, pressure in the pipeline can import in the gap 3 of metal ring 1, thereby when sealing surface external force changes, come sealing surface pressure is compensated,, realize self-strengthening with the seal pressure of stabilized seal pad by the pressure medium transmission.
Claims (3)
1. semiarc sealing gasket, it is characterized in that: it comprises metal ring (1), the upper surface that is installed in described metal ring (1) and the coating on the lower surface (2) that the longitudinal section takes the shape of the letter U, described metal ring (1) has gap (3), in described gap (3), be filled with hard packing (4), and the filling density of described packing (4) is less than 10 gram/cubic centimetres greater than 0 gram/cubic centimetre.
2. semiarc sealing gasket according to claim 1 is characterized in that: also be installed with limit collar (5) on the outer ring of described metal ring (1).
3. semiarc sealing gasket according to claim 1 is characterized in that: described coating (2) protrudes from 0.1～10 millimeter on the surface of metal tube.
