Abstract
The utility model discloses a novel tooth-shaped gasket comprising a gasket body. The upper and the lower end surfaces of the gasket body are respectively provided with a tooth-shaped groove; two ends of the gasket body are individually provided with a positioning groove; and the surfaces of the tooth-shaped grooves are respectively covered with a Teflon film. Compressive strength, high temperature resistance and corrosion resistance of the tooth-shaped gasket can be effectively improved with actions of the tooth-shaped grooves, the positioning grooves and the Teflon films, so use performance and seal effect of the novel tooth-shaped gasket can be greatly increased.
Description
Technical field
The utility model relates to a kind of pad, particularly a kind of tooth pad.
Background technique
Grooved metal gasket refers to that the accurate lathe of general use is processed into concentric groove at two faces of metal stainless steel flat gasket, according to different media, can select Expanded graphite, PTFE, without asbestos slate or some other soft metal, sticks on two of pad.Also can not be with sealing layer directly to use, and can reach good sealing effect, but easily the surface of flange be caused damage in high pressure occasion.
Model utility content
The purpose of this utility model is in order to overcome above deficiency, and a kind of tooth pad is provided, and when keeping excellent sealing effect, prevents from flange surface to cause damage.
The purpose of this utility model realizes like this:
A kind of tooth pad of the utility model, comprises body, and wherein, described body upper and lower end face is evenly provided with serrate slot; Described body two ends are provided with locating slot; Described serrate slot surface is provided with polytetrafluoroethylene film.
Above-mentioned a kind of tooth pad, wherein, described serrate slot is that steel fiber is composited.
Above-mentioned a kind of tooth pad, wherein, described locating slot is that convex is square, is symmetrical set.
Above-mentioned a kind of tooth pad, wherein, described polytetrafluoroethylene film thickness is 0.2mm-0.5mm.
Above-mentioned a kind of tooth pad, wherein, the fleam of described serrate slot is 90 degree.
Compared with prior art, the utlity model has following advantage:
1), by steel fiber structure serrate slot, effectively improve compressive strength and the resistance to high temperature of pad.
2) locating slot is set, accurately locating flange sealing station, improves sealing effect.
3) polytetrafluoroethylene film substitutes soft metal sealing layer in the past, improves sealing when improving pad corrosion resisting property.
A kind of tooth pad of the utility model, by serrate slot, locating slot.The effect of polytetrafluoroethylene film, can effectively improve compressive strength, heat-resisting quantity, the corrosion resistance of grooved metal gasket, has greatly improved a kind of usability and sealing effect of tooth pad.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of tooth pad of the utility model, comprises body 1, and wherein, described body 1 upper and lower end face is evenly provided with serrate slot 2; Described body 1 two ends are provided with locating slot 3; Described serrate slot 2 surfaces are provided with polytetrafluoroethylene film 4; Described serrate slot 2 is composited for steel fiber; Described locating slot 3 is that convex is square, is symmetrical set; Described polytetrafluoroethylene film 4 thickness are 0.2mm-0.5mm; The fleam of described serrate slot 2 is 90 degree.
A kind of tooth pad of the utility model, by the effect of serrate slot 2, locating slot 3, polytetrafluoroethylene film 4, can effectively improve compressive strength, heat-resisting quantity, the corrosion resistance of grooved metal gasket, greatly improve a kind of usability and sealing effect of tooth pad.
The performance data of the prepared a kind of tooth pad of the utility model is as following table:
