Abstract
The utility model relates to a fiber cloth material composite layer non metal plane sealing pad, comprising a middle layer(1) and a composite layer. The middle layer is made of non metal pad material. One side of the middle layer is agglutinated with the composite layer. The composite layer is composed of fiber cloth(7) and a perduren layer(9). One side of the fiber cloth is agglutinated with the middle layer into an integration. The other side of the fiber cloth is solidified with the perduren layer. The middle layer made of non metal pad material can be extensible paper, fish paper, red inverse cypress, rubber cork wood or fiberboard material. The layer on the fiber cloth can be butadiene acrylonitrile rubber, polyamine ester or silicon rubber. The middle layer can be agglutinated with a composite layer on both sides. Because of the high intensity of the fiber cloth material composite layer non metal plane sealing pad, good rebound elasticity and tightness, according to different mechanical seal requirement, the utility model can be chosen to use widely.
Description
One. technical field
The utility model relates to mechanical parts plane sealing pad.
Two. technical background
For fear of the leakage of flowing medium, the sealing that contacts the plane between part is particularly important in the electronic product, and the mounting plane gasket seal is present the most frequently used method, for example adopts extensible paper, fish paper, cork, red anti-cypress and rubber sheet gasket etc.In order to increase the intensity of plane sealing pad, also have on the single or double of steel or aluminium matter pad, sulfuration one deck oil resistant rubber layer constitutes metal intermediate layer composite plane gasket seal.Above-mentioned various plane sealing pad, the problem that exists is that the pad comprehensive strength is low, and compression resilience is poor, and sealability is bad, so cause seepage in the product using process easily, when maintenance, inspection or mounting or dismounting, pad damages easily, scrappage and maintenance cost height especially, even in order to guarantee sealing, sometimes the sealer of having to use, and the removing of sealer difficulty relatively, thus the product turbidity test can be influenced.
Three. summary of the invention
The utility model adopts fiber cloth composite bed nonmetallic material adhesive structure, the compound layer of viscose fibre cloth high strength on the mesosphere that the non-metallic pad sheet material is formed, thereby improve the comprehensive strength and the sealability of gasket seal, mounting or dismounting are convenient, can reuse.
The utility model is achieved in that the nonmetal plane sealing pad of a kind of fiber cloth composite bed, form by mesosphere and composite bed, the mesosphere is the non-metallic pad sheet material, be bonded with composite bed on the one side in mesosphere, composite bed is made up of fiber cloth and vulcanized rubber layer, the one side of fiber cloth is bonded as one with the mesosphere, is solidified with the vulcanized rubber layer on the fiber cloth another side.
The nonmetal plane sealing pad of above-mentioned fiber cloth composite bed, mesosphere are nonmetallic gasket elastic properties of materials paper, fish paper, red anti-cypress, rubbery cork or fibrous plate.
The nonmetal plane sealing pad of above-mentioned fiber cloth composite bed, the vulcanized rubber layer on the fiber cloth that is bonded as one with the mesosphere is a nitrile rubber, polyamine fat or silicone rubber.
The nonmetal plane sealing pad of above-mentioned fiber cloth composite bed also is bonded with composite bed on the another side on mesosphere (1).
Because the comprehensive strength height of the nonmetal plane sealing pad of fiber cloth composite bed, frangibility not in the use, rebound elasticity and good seal performance, so can reuse, long working life can be applicable to the high temperature of different medium, high pressure, the seal request of oil resistant.
Four. description of drawings
Fig. 1 is the nonmetal plane sealing pad of a fiber cloth composite bed schematic representation; Fig. 2 is the plan view of Fig. 1.
Among the figure, 1 is the mesosphere, and 2 is last plane, and 3 is screw, and 4 is last composite bed, and 5 are following composite bed, and 6 is lower plane, and 7 is fiber cloth, and 8 is endoporus, and 9 is the vulcanized rubber layer.
Five, preferred forms
Preferred forms of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1,2, the nonmetal plane sealing pad of fiber cloth composite bed, mesosphere 1 is made by nonmetallic gasket elastic properties of materials paper, and thickness is (0.8～1.5) millimeter.All be bonded with composite bed 4 and following composite bed 5 on plane 2 on the mesosphere 1 and the lower plane 6.Last composite bed 4 and following composite bed 5 are made up of fiber cloth 7 and oil resistant vulcanized rubber layer 9.The thickness of fiber cloth 7 is 0.15 millimeter.Vulcanized rubber layer 9 is one by the one side sulfuration of sulfuration process and fiber cloth 7, and the another side of fiber cloth 7 and mesosphere 1 usefulness chloroprene rubber adhesive agent are bonded as one, and vulcanized rubber layer 9 equals 0.2 millimeter nitrile rubber for thickness.The endoporus 8 in mesosphere 1 is shaped as the circular flow channel hole of sealing medium.When the thickness that is bonded as one with last composite bed 4 and following composite bed 5 when mesosphere 1 was (0.5～1.5) millimeter, main sealability was sealing load: 15Mpa.Heatproof :-35 ℃～120 ℃.Sealing medium: oil, gas, water.Seal clearance: (0～0.20) millimeter.The mesosphere 1 of the nonmetal plane sealing pad of fiber cloth composite bed also can be by non-metallic pad sheet material fish paper, red anti-cypress, and rubbery cork or fibrous plate are made.Vulcanized rubber layer 9 also can be polyamine fat or silicone rubber.Endoporus 8 shapes in mesosphere 1 also can be rectangle, trapezoidal, oval, rhombus, triangle or polygon.Also can there be composite bed in mesosphere 1 for one side.
According to the different sealing structure and to sealing medium, performance requirement, can carry out combination selection to pad.Because its good airproof performance is convenient to mounting or dismounting, can reuse, low cost of manufacture is so be specially adapted to automobile, tractor, motorcycle, lathe, compressor, diesel engine, gear-box, the plane sealing of layer body part and stamping part.
