Abstract
The utility model relates to a teflon seal spare, which comprises a body, the body is equipped with two and above draw -in groove, the draw -in groove is located on the body, the body outside is provided with the metal frame, the metal frame cup joint in on the body, the body includes polytetrafluoroethylene layer and filling layer, the filling layer is located the polytetrafluoroethylene in situ, be equipped with the fibrous layer between filling layer and the polytetrafluoroethylene layer, the utility model discloses a metal frame is fixed in the outside of body, simultaneously on this internal polytetrafluoroethylene layer of installing to the polytetrafluoroethylene layer has the characteristics that the leakproofness is good, corrosion resistance is good and high temperature resistant good, both can increase corrosion resistance and crushing resistance, can increase the leakproofness again, and simple structure accords with the market demand, is fit for large -scale production.
Description
Technical field
The utility model relates to seal technical field, relates in particular to a kind of teflon seal.
Background technology
Along with the arrival of information age; the application place of seal also constantly expands; especially for the sealing in pipeline; its object is exactly to avoid pipeline to be subject to erosion and the sealing effectiveness of water impurity; thereby affect the pipeline normal work and use time limit; but seal on traditional market is the made seal of the homogenous material such as rubber and plastics mostly; the seal high temperature resistant; acid and alkali resistance corrosive power is poor; and its crushing resistance ability is also poor; cannot better protect the sealing of pipeline, be badly in need of in the market a kind of seal of good airproof performance.
Utility model content
For the present situation of above-mentioned prior art, the part teflon seal that provides a kind of good airproof performance, good corrosion resistance and crushing resistance good is provided technical problem to be solved in the utility model.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of teflon seal, comprise body, described body is provided with two and above draw-in groove, described draw-in groove is positioned on described body, described body arranged outside has metal frame, described metal frame is socketed on described body, described body comprises polytetrafluoroethylene floor and packed layer, described packed layer is positioned at described polytetrafluoroethylene floor, between described packed layer and polytetrafluoroethylene floor, be provided with fibrage, this polytetrafluoroethylene floor has good airproof performance, good corrosion resistance and high temperature resistant good feature, thereby effectively raise the corrosion resistance of body, metal frame is fixed on the outside of body simultaneously, effectively raise the crushing resistance of body.
Preferably, described draw-in groove quantity is 4, and described draw-in groove is equidistantly evenly distributed on body.
Preferably, described draw-in groove is semi-circular shape.
Compared with prior art, the utility model has the advantage of: the utility model is fixed on the outside of body by metal frame, polytetrafluoroethylene floor is installed simultaneously in body, and polytetrafluoroethylene floor has good airproof performance, good corrosion resistance and high temperature resistant good feature, both can increase corrosion resistance and crushing resistance, and can increase again sealing, the utility model is simple in structure, accord with the demands of the market, be applicable to large-scale production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1-body; 2-draw-in groove; 3-metal frame; 4-polytetrafluoroethylene floor; 5-packed layer; 6-fibrage.
Detailed description of the invention
As shown in Figure 1, a kind of teflon seal, comprise body 1, described body 1 is provided with two and above draw-in groove 2, described draw-in groove 2 is positioned on described body 1, described body 1 arranged outside has metal frame 3, described metal frame 3 is socketed on described body 1, described body 1 comprises polytetrafluoroethylene floor 4 and packed layer 5, described packed layer 5 is positioned at described polytetrafluoroethylene floor 4, between described packed layer 5 and polytetrafluoroethylene floor 4, is provided with fibrage 6, and described draw-in groove 2 quantity are 4, described draw-in groove 2 is equidistantly evenly distributed on body 1, and described draw-in groove 2 is semi-circular shape.
Manually utilize machine that polytetrafluoroethylene floor, fibrage and packed layer are pressed into seal, open 4 draw-in grooves at the upper surface of seal, and metal frame is wrapped in to the inside seal, finally utilize draw-in groove to be fixed on pipeline simultaneously.
The utility model is fixed on the outside of body by metal frame, polytetrafluoroethylene floor is installed simultaneously in body, and polytetrafluoroethylene floor has good airproof performance, good corrosion resistance and high temperature resistant good feature, both corrosion resistance and crushing resistance can have been increased, can increase again sealing, simple in structure, accord with the demands of the market, be applicable to large-scale production.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these amendments or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment technical scheme of the utility model.
