Abstract
The utility model relates to a completely rubber covered metal seal gasket used for fluid piping and mechanical device sealed interfaces. The completely rubber covered metal seal gasket takes a metal gasket as a main body; a layer of sealed rubber is covered on the external surface of the metal gasket; the metal gasket and the sealed rubber layer are made into a tightly combined seal gasket with high overall performance. The gasket can be widely used in the sealed interfaces of pipelines and mechanical devices for transferring different fluid mediums, which has the advantages of high mechanical strength, reliable sealing, easy operation, high temperature resistance, corrosion resistance, long service life, simple manufacturing process and low cost.
Description
Technical field
The utility model relates to a kind of full encapsulate metallic gasket that is used for fluid circuit and mechanical device sealed interface.
Background technique
Being used for to transmit oil, water, steam at present is the High Temperature High Pressure pipeline attached seal of medium, mostly adopts metallic shim or nonmetallic gasket to seal.When adopting the metallic shim sealing, because pad is different with the used material of connecting pipeline, to add design, reasons such as improper are installed, it is assembled the sealing surface of fit sealing after good still can be gapped, leakage is arranged, and its pad is perishable, and is particularly particularly serious under High Temperature High Pressure.Nonmetallic gasket mostly is a rubber cushion, when adopting this mode to seal, because rubber cushion is different with coupled hardness, be difficult to during construction fast pad accurately is positioned the sealed mouth place, bring inconvenience to construction, simultaneously improper a little to the impacting force of pad when construction, very easily damage pad, and pad only can use once and just scraps.In order to address the aforementioned drawbacks, invention has designed new technological scheme again, applies the sealer face on the surface of promptly encircling in metallic shim, though this kind technological scheme has overcome the deficiency of such scheme.But it fails metallic shim is carried out totally-enclosed coating by sealant layer, and promptly uncoated sealer face on the surface of metallic shim outer shroud causes the sealing surface out-of-flatness of sealing gasket, makes and easily causes the generation of leakage by the sealing surface unbalance stress.Simultaneously in use, the part that leaks outside of metallic shim is very easily corroded again, causes the damage of pad, has reduced the working life of pad.
Summary of the invention
The purpose of this utility model is the improvement to existing sealing gasket, so that full encapsulate metallic gasket a kind of novelty, good seal performance, long service life to be provided.
The utility model purpose is achieved in that this full encapsulate metallic gasket based on metallic shim, and at outer surface coating one deck sealant layer of metallic shim, its metallic shim and sealant layer are made an integral sealing pad of combining closely.
Above-mentioned said sealing gasket is a ring spacer, and the inner ring surface of its metal washer is provided with locator protrusions, and the glue face of the top of locator protrusions and ring spacer is on same surface.The inboard wall thickness of seal washer cross section is a level and smooth extended surface between internal and external walls more than or equal to the wall thickness of outer side wall.The sealant layer of sealing gasket is a high temperature high voltage resistant glue-line, and its bed thickness is the 0.5---1.5 millimeter.
The utility model is by metallic shim and the sealant layer high-performance sealing gasket in aggregates of combining closely.This pad can be widely used in transmitting in the sealed interface of the pipeline of different fluid medium and mechanical device, its mechanical strength height, and sealing is reliable, and is easy to use, can be high temperature resistant, anticorrosive, long service life.And manufacturing process is simple, and is with low cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
As shown in Figure 1, 2, the form structure of sealing pad is an annular seal packing ring, and it is based on metal washer 1, coats one deck sealant layer 2 at the outer surface of metal washer 1, and sealant layer 2 coats metal washer 1 in sealing and its fully.The integral sealing pad to combine closely is made in metal washer 1 and sealant layer 2 hot pressing.Can locate and prevent landing quickly and accurately when sealing gasket is used, the inner ring surface of its metal washer 1 is provided with 3 locator protrusionss 3 in mutually, and locator protrusions 3 is that the glue face of its pinnacle of triangular shape structure and ring spacer is on same surface.The inboard wall thickness of seal washer cross section is more than or equal to the wall thickness of outer side wall, and the thickness of present embodiment madial wall is 2.5 millimeters, and the thickness of outer side wall is 2 millimeters, is a level and smooth extended surface between internal and external walls.Sealant layer 2 is selected the rubber material of high temperature high voltage resistant for use, and its bed thickness is the 0.5---1.5 millimeter, and the glue-line of present embodiment madial wall is thick to be 1 millimeter, and the glue-line of outer side wall is thick to be 0.75 millimeter.
Claims (4)
