Abstract
The utility model relates to a plastic sealing ring with an elliptic cross section. The shape of the cross section is in an ellipse shape; the diameter of the cross section in the X direction must be greater than the diameter in the Y direction; the plastic seal ring with an elliptic cross section is manufactured by plastic materials and is arranged between two flange surfaces, and the sealing can be realized through the plastic deformation of the cushion ring. Accordingly, the plastic sealing ring with an elliptic cross section has no special requirements to the shape of the connected flange surfaces; the grinding treatment is not needed; the pre-tensioning requirement is low; the sealing surface is narrow, the sealing effect is favorable, and the service life is long. The plastic sealing ring with an elliptic cross section can be used for the pressure container of the middle and low voltage with the sealing pressure which is lower than 6.4MPa. According to the requirement, the plastic sealing ring with an elliptic cross section can be manufactured to be the pressure series with different diameters, and the plastic sealing ring with an elliptic cross section can have great popularization value in the middle and low voltage sealing.
Description
The utility model relates to the seal ring that solid packing is arranged between relatively-stationary sealing surface.
Choosing of sealing configuration pattern between the connection pressurized container flange and sealing material is directly connected to the effect of sealing, the size of bolt force and flange moment of flexure.In the prior art field, the general employing of the mesolow sealing forced seal of≤6.4MPa, the sectional shape of seal ring has O shape, plain cushion shape, corrugated profile of tooth etc., all these seal rings, not that sealing surface is wide, sealing is unreliable, make comparatively complexity exactly or waste of material is big, cost is high, and be a life cycle general working life.Adopt in the high pressure sealing of＞6.4MPa and between the flangeseal face, to add oval steel loop, the diameter of steel loop cross section x direction is less than y direction diameter, and must be placed in the special flange plate that has dovetail groove, must be between two sealing surfaces through ground, need give tight power greatly, steel loop integral body does not produce plastic deformation in the seal process.
The purpose of this utility model is that it provides a kind of seal ring that elliptic cross-section is made with plastic material that has, and can be installed in easily between face-flange dish or the concave-convex shape cross section flange plate, can overcome the deficiency of prior art.
For achieving the above object, the technical solution of the utility model is that the sectional shape of seal ring is oval, and cross section x direction diameter must be installed between two flanged surfaces greater than y direction diameter.
The utility model has the advantages that, because sectional shape is oval, and make with plastic material, therefore there is not the special shape requirement with coupled flanged surface, also need not ground, give and critically ask low, sealing surface is narrow, good sealing effect, life-span are long, be applicable to the various media of sealing load≤6.4MPa mesolow, in the pressurized container of various serviceability temperatures, can be made into the pressure series of different-diameter as required, and cost is low, therefore has great promotional value in the mesolow sealing.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing, structure diagram of the present utility model.
As shown in the figure, seal ring 1 be installed in flanged surface 2,2 ' between, major axis x direction diameter is 1.2～5 times of minor axis y direction diameter, according to seal request, its material can be softer metals or nonmetallic material such as plastics, rubber such as copper, aluminium, flanged surface can be that the plane also can be the flange in concave-convex shape cross section, and flanged surface also need not polishing and handles, and sealing is that the plastic deformation of back cushion circle realizes.
Claims (3)
