Abstract
The utility model relates to a seal washer for flange plates, more specifically say the seal washer for flange plates who especially uses in the chemical industry evacuation equipment to polytetrafluoroethylene is the material, sets up polytetrafluoroethylene ring form (2) on outer circumference (1) of polytetrafluoroethylene ring form (2), the interval is provided with " trapezoidal " groove (3), " trapezoidal " groove (3) is in evenly distributed is gone up in outer circumference (1) of polytetrafluoroethylene ring form (2). The utility model relates to a seal ring of ring flange butt joint, its is high temperature resistant, high -pressure, corrosion -resistant, has good compression ratio and rebound degree, simple structure and can guarantee gas tightness good between the ring flange can, be suitable for the chemical industry evacuation equipment very much, for a long time good vacuum inside the retaining device.
Description
Technical field
The utility model relates to flangeseal packing ring, is more particularly especially applied in the flangeseal packing ring in chemical industry vaccum-pumping equipment.
Background technique
In synthetic leather manufacturing enterprise wet process furnish process for preparation in, kettle cover needs frequently to open, and often contact or object collision with material, be mainly the kettle cover upper sealing washer of material with asbestos in prior art, its outer peripheral surface is full circle, but its use in cracky, working life short, sealing reliability can not meet the demands.
Summary of the invention
The utility model is the deficiency for avoiding existing for above-mentioned prior art, provides a kind of flangeseal packing ring, is applied in chemical industry vaccum-pumping equipment, to improving working life, ensure sealing reliability.
The utility model is that technical solution problem adopts following technological scheme:
The structural feature of the utility model flangeseal packing ring is: be material with teflon, arranges teflon annular solid, on the excircle of described teflon annular solid, is arranged at intervals with " trapezoidal " groove.
The structural feature of the utility model flangeseal packing ring is also: described " trapezoidal " groove is uniformly distributed on the excircle of described teflon annular solid.
The structural feature of the utility model flangeseal packing ring is also: the degree of depth of described " trapezoidal " groove is not more than 1/4th of the radial thickness of teflon annular solid.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model take teflon as material, and it is high temperature resistant, high pressure resistant, corrosion-resistant, has good compressibility and rebound degree, good sealing effect, long service life.
2, the utility model arranges " trapezoidal " groove on its excircle, relative to full circle, it is that the outer periphery of dentation makes packing ring more can fit in press-fiting flanged surface, obtain more superior tightness, be specially adapted to chemical industry vaccum-pumping equipment, the degree of vacuum that can device interior be kept for a long time good.
3, the utility model take polytetrafluoroethylene ring as material, and it is that the excircle of dentation is easy to machine shaping more, and not fragile.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: 1 excircle, 2 teflon annular solids, 3 dovetail grooves.
Embodiment
See Fig. 1, in the present embodiment, flangeseal packing ring is material with teflon, arranges teflon annular solid 2, on the excircle 1 of described teflon annular solid 2, be arranged at intervals with " trapezoidal " groove 3.
In concrete enforcement, " trapezoidal " groove 3 is uniformly distributed on the excircle 1 of described teflon annular solid 2.In order to proof strength, the degree of depth of " trapezoidal " groove 3 is not more than 1/4th of the radial thickness of teflon annular solid 2.Utilize technological scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technological scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
Claims (2)
1. a flangeseal packing ring, it is characterized in that: take teflon as material, teflon annular solid (2) is set, on the excircle (1) of described teflon annular solid (2), be arranged at intervals with " trapezoidal " groove (3), described " trapezoidal " groove (3) are uniformly distributed on the excircle (1) of described teflon annular solid (2).
2. a kind of flangeseal packing ring according to claim 1, is characterized in that: the degree of depth of described " trapezoidal " groove (3) is not more than 1/4th of the radial thickness of teflon annular solid (2).
