Abstract
The utility model discloses a sealing ring which is high temperate resistant and strongly corrosion resistant; the sealing ring comprises a main body; at least a protective layer is covered on the main body; all seams of the protective layer are staggered. The sealing ring is in particular applicable to mechanical sealing devices with high temperature and strong corrosion resistance.
Description
Technical field
The utility model relates to the seal ring that is used to prevent the sealed medium leakage.
Background technique
At present, known seal ring is all formed through the high temperature compacting by rubber usually, and this seal ring seals all gases and fluid by the amount of deformation that the elasticity of rubber own produces.But,, restricted widening of its application because of the non-refractory of rubber own, corrosion resistance are not strong.In applying it to the stronger environment of high temperature or corrosivity, will shorten greatly its working life, increased the maintenance rate that uses equipment.
The model utility content
A technical problem to be solved in the utility model is: a kind of high temperature resistant, seal ring that corrosion resistance is strong is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: seal ring comprises: the seal ring body, on described seal ring body, be coated with the anticorrosion high temperature resistance protective layer of one deck at least, and the sealing of institute's matcoveredn staggers mutually.
Above-mentioned anticorrosion high temperature resistance protective layer is made by teflon.
On above-mentioned seal ring body, be coated with the two-layer anticorrosion high temperature resistance protective layer of making by teflon, and the sealing of two-layer protective layer staggers mutually.
The beneficial effects of the utility model are: the utility model is owing to coated the anticorrosion high temperature resistance protective layer of one deck at least on the seal ring body; make that its anticorrosive property and high-temperature stability have obtained strengthening significantly; thereby widened its application; prolong its working life, reduced the maintenance rate that uses equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the cross section of the described seal ring of Fig. 1;
Among Fig. 1, Fig. 2: 1, seal ring body, 2, protective layer, 3, sealing, 4, protective layer, 5, sealing.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As depicted in figs. 1 and 2, seal ring described in the utility model comprises: seal ring body 1, on described seal ring body 1, be coated with two-layer anticorrosion high temperature resistance protective layer 2 and 4, and the sealing 3 and 5 of two-layer protective layer staggers mutually.In the present embodiment, described anticorrosion high temperature resistance protective layer 2 and 4 is made by teflon.By the lathe tool of the special forming belt arc round angle that grinds, will be contained on the teflon rod rubber ring in alignment footpath.By forward, oppositely turning processing, coat at the external diameter of rubber ring double-deck, the tetrafluoroethylene overcoat of control thickness.And the size of each processing calculated, make the external diameter of seal ring and line footpath size Control within standard.
The utility model is owing to coated the anticorrosion high temperature resistance protective layer of one deck at least on the seal ring body; make that its anticorrosive property and high-temperature stability have obtained strengthening significantly; thereby widened its application, prolonged its working life, reduced the maintenance rate that uses equipment.
Use is when high temperature and mordant operating mode, and what contact with medium is outside teflon part, but play the compensation with buffer function be the rubber ring of inner core.And according to different media and temperature, can select the rubber ring of unlike material, to satisfy the compensating action in different operating modes.Thereby make this novel outstanding temperature tolerance, rotproofness both taken into account, added the good compensation performance that is equal to rubber ring simultaneously again.Reached and be applicable to high temperature and strong rotten operating mode, the purpose of minimizing maintenance rate.
Claims (3)
1. seal ring, comprising: the seal ring body is characterized in that: be coated with the anticorrosion high temperature resistance protective layer of one deck at least on described seal ring body, the sealing of institute's matcoveredn staggers mutually.
2. seal ring as claimed in claim 1 is characterized in that: described anticorrosion high temperature resistance protective layer is made by teflon.
3. seal ring as claimed in claim 2 is characterized in that: be coated with the two-layer anticorrosion high temperature resistance protective layer of being made by teflon on described seal ring body, and the sealing of two-layer protective layer staggers mutually.
