Abstract
The present invention relates to a semi-arc sealing gasket and a manufacture method thereof. The machined sealing gasket includes a metal ring having a U-shape longitudinal section, and a coating layer mounted between the upper surface and the lower surface of the metal ring. The metal ring has a gap which is filled with a rigid filling with a filling density in a range of 0-10 g/cubic centimeter. Because the metal ring is pressed to a structure having a U-shape longitudinal section, so the U-shape gap can be filled with fillings and the filling density can be adjusted, thereby the adjustment for the compaction of sealing members and the rebound degree can be realized by control the density of the fillings, and the anti-press ability of the gasket is improved and the sealing effect is enhanced.
Description
Technical field
The present invention relates to a kind of gasket seal and manufacture method thereof, relate in particular to a kind of semiarc sealing gasket and manufacture method thereof.
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
Thereby the object of the invention is exactly to provide a kind of semiarc sealing gasket and manufacture method thereof that realizes the compression to Sealing, rebound degree adjustment enhancing anti-pressure ability for solving the deficiencies in the prior art.
Technological scheme of the present invention 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, is filled with the packing that filling density is 0～10 gram/cubic centimetre in described gap.
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.
The material of described metal ring is one or more the mixture in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), the titanium, described coating (4) is one or more the composite in graphite, fiber, teflon, the resin, and described packing (8) 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.
The material of described limit collar is a kind of in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), the titanium.
The present invention also provides a kind of manufacture method of semiarc sealing gasket, and it comprises the steps:
(a), an annular metal is pressed into the metal ring that the cross section takes the shape of the letter U, thus make metal ring have the gap;
(b), in the gap of metal ring, fill packing, and make that filling density is 0～10 gram/cubic centimetre;
(c), on the upper surface of metal ring and lower surface, coating is installed respectively.
In the step (c), when coating is installed, make coating protrude from 0.1～10 millimeter of metal ring surface.
Step (c) is installed limit collar afterwards on the outer ring of metal ring.
In the step (b), packing is selected 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 for use.
Owing to adopted above-mentioned technological scheme, advantage of the present invention is: because the metal ring compacting is the structure that the longitudinal section is a U-shaped, thereby 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 invention;
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 the specific embodiment of the present invention is described in further detail.
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.
The invention still further relates to a kind of manufacture method of semicircle gasket seal, this method is used to produce the gasket seal with above technical characteristics, and it comprises the steps:
(a), annular metal compacting is the metal ring 1 that the cross section takes the shape of the letter U, thus make metal ring 1 have gap 3;
(b), in the gap 3 of metal ring 1, fill out hard packing 4, and make that the density of filling is 0～10 gram/cubic centimetre;
(c), on the upper surface of metal ring 1 and lower surface, coating 2 is installed respectively.
In the step in the above step (c), when coating 2 is installed, make coating 2 protrude from 0.1～10 millimeter of metal ring surface.
In the step (b), packing 4 is selected 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 for use.
At last, limit collar 5 is installed and promptly makes semicircle gasket seal of the present invention on the outer ring of metal ring 1.
