Abstract
The invention relates to a sealing gasket. The sealing gasket comprises a metal inner ring, a metal outer ring which is enclosed on the external circumference of the metal inner ring, and a non-metal sealing ring which is embedded between the metal inner ring and the metal outer ring, and the side of a radial section of the metal outer ring has a prominent geometric shape, optimally an arc shape. The sealing gasket is particularly suitable for sealing in a groove; and when the sealing gasket is used for sealing in the groove, line sealing between metal and a groove wall can be realized, requirement on good sealing performance can be met, surface sealing between the non-metal sealing ring and a sealed surface can be realized, and the capacity that the sealing gasket resists the fluctuation of complex working conditions can be improved, so double sealing functions can be realized, and the sealing effect of the sealing gasket can be improved.
Description
Technical field
The present invention relates to a kind of gasket seal, be specially adapted to sealing in the groove
Background technique
gasket seal can be divided into metallic packing and nonmetal gasket seal etc. by material, and the seal form of gasket seal mainly contains face seal and linear sealing.In general; Metallic packing all is linear sealing form (influenced by machining accuracy and be difficult to make face seal, like concentricity, out of roundness and inclination etc.) basically, and the area of contact of pad and Work piece sealing face is little; Pressure is big; Sealing effect is better, but this linear sealing structure is resisted the ability of working condition fluctuation, loses efficacy easily in the using process.But not mostly metallic packing is the face seal form; Area of contact between pad and the Work piece sealing face is bigger; The sealing effect of relative linear sealing is relatively poor under the same pressure condition; And performances such as the general nonmetallic gasket strength of materials, hardness are also good not as metallic material, and therefore this pad is difficult to realize the sealing applications under the high parameter condition
Summary of the invention
technical problem to be solved by this invention is the deficiency that overcomes existing technology, and a kind of advantage separately and better gasket seal of sealing effect that has combined linear sealing and face seal is provided.
For solving above technical problem, the present invention takes following technological scheme:
a kind of gasket seal; Comprise ring in the metal, be around in the metal outer shroud of ring periphery in the said metal and be embedded the nonmetal seal ring between the ring and said metal outer shroud in said metal, and the outside of the radial section of said metal outer shroud is outstanding geometrical shape.
preferably, the outside of the radial section of said metal outer shroud is an arc.
preferably, the thickness of said nonmetal seal ring is greater than the ring and the thickness of said metal outer shroud in the said metal.
preferably, the radial section of ring is square in the said metal.
preferably, the material of ring and said metal outer shroud is selected from a kind of in carbon steel, stainless steel, copper, aluminium, monel metal, the severe nickel of English and the titanium in the said metal.
preferably, the material of said nonmetal seal ring is selected from a kind of in graphite, mica and the teflon.
Because the enforcement of above technological scheme, the present invention compared with prior art has following advantage:
gasket seal of the present invention utilizes the outstanding geometrical shape in the metal outer shroud outside, can realize the linear sealing of metal outer shroud and cell wall when in being used for groove, sealing, and makes gasket seal can satisfy the requirement of high leak tightness; Utilize the upper and lower surfaces of nonmetal seal ring to contact the realization face seal simultaneously, can reach the sealing requirements under complex working condition (like staggered variations such as pressure, temperature, the load) condition with carried out face by sealing surface.
Description of drawings
Below in conjunction with accompanying drawing and concrete mode of execution the present invention is done further detailed explanation:
Fig. 1 is the plan view of gasket seal of the present invention;
Fig. 2 is the radial cross-section of gasket seal of the present invention;
wherein: 1, ring in the metal; 2, nonmetal seal ring; 3, metal outer shroud.
Embodiment
are done further detailed explanation below in conjunction with concrete embodiment to the present invention, but are not limited to these embodiments.
see figures.1.and.2, according to the gasket seal of present embodiment by encircle 1 in the metal, metal outer shroud 3 and be embedded that the nonmetal seal ring 2 between the ring 1 and metal outer shroud 3 constitutes in metal.Wherein ring 1 selects for use the same metal of material to be made with metal outer shroud 3 in the metal; Available material has carbon steel, stainless steel, copper, aluminium, monel metal, the severe nickel of English and titanium etc., and the material of nonmetal seal ring 2 can be graphite, mica or teflon.When making the present embodiment gasket seal, nonmetal seal ring 2 can be in many ways (as knock etc.) embeds in the metal between the ring 1 and metal outer shroud 3, make encircle in nonmetal seal ring 2 and the metal 1 and metal outer shroud 3 between close proximity or offset.
The outside of the radial section of
metal outer shroud 3 is outstanding geometrical shape, and preferably arc is circular arc in the present embodiment; In addition, the thickness of nonmetal seal ring 2 is greater than the thickness of ring 1 in the metal and metal outer shroud 3, and the radial section of ring 1 is square in the metal.
present embodiment gasket seal is particularly suitable for sealing in the groove; Like the female flange face seal of pipeline, machinery etc., when being positioned in the groove sealing, the sealing pad can either realize the linear sealing between metal and the cell wall, satisfy the high leak tightness requirement; Can realize the face seal between nonmetal seal ring and the flanged surface again; Improve gasket seal and resist the ability of complex working condition fluctuation, thereby realized the double seal function, improve the sealing effect of gasket seal.
More than the present invention has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention
