Abstract
The invention discloses an anti-corrosion and wear-resisting sealing piece. The anti-corrosion and wear-resisting sealing piece comprises an annular body prepared from a rubber material, and an L-shaped reinforcement rib nested inside the body, wherein an inner ring of the body respectively extends towards the front side and the back side to form an anti-dust lip and a sealing structure; a gap is reserved between the sealing structure and an outer ring of the body; an elastic piece is arranged inside the gap in the position near the sealing structure; a PTFE (Poly Tetra Fluoro Ethylene) layer at least covers the sealing structure on the surface of the body. The anti-corrosion and wear-resisting sealing piece has the beneficial effects in that the entire enough intensity, the durability and the good anti-dust effect can be ensured through the sealing piece provided by the invention; the dry abrasion can be prevented, friction force and the friction coefficient can be reduced, and the corrosion caused by thick acid-base and chemicals resistance can be realized through the PTFE layer covering the surface of the body; the properties of the sealing piece can be improved; the service life is prolonged; the production cost is reduced.
Description
Technical field
The present invention relates to a kind of Sealing, be specifically related to a kind of Sealing of anticorrosion antiwear.
Background technique
Sealing is to prevent that fluid or solid particle are from leaking between adjacent junction plane and preventing that introduced contaminants is as material or the part of the component of the intrusion machinery equipment inside such as dust and moisture, be widely used in numerous industries such as household electrical appliances, motor car engine, chemical industry, on market there is the problems such as insufficient strength, working life be short in existing Sealing mostly, needs improvement badly.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of Sealing, intensity is high, and sealing and dustproof is effective, has good antiseptic property and wear-resisting property, long service life.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of Sealing of anticorrosion antiwear, comprise: the annular body of being made by rubber material, be embedded in intrinsic L shaped stiffening rib, interior hoop front side and the rear side of described body extend to form respectively dust excluder lips and sealing configuration, between described sealing configuration and the outer shroud of body, there is a space, in described space, next-door neighbour's sealing configuration arranges an elastic component, and the surface of described body at least covers PTFE layer at sealing configuration place.
The whole surface of aforementioned body all covers PTFE layer.
Aforementioned elastic parts is spring.
The one side that aforementioned sealing configuration is adjacent with body outer shroud is formed with arc receiving groove, and described spring is arranged in arc receiving groove.
Aforementioned dust excluder lips be obliquely installed and and body between be provided with a fillet surface.
The leading portion of aforementioned dust excluder lips is concordant with the end of body.
The front side of the outer shroud of aforementioned body and rear side are all formed with chamfering.
Usefulness of the present invention is: Sealing of the present invention, guaranteed whole sufficient intensity, durable, good dustproof effect, at body surface covering PTFE, can play and prevent dry grinding, reduce frictional force and friction factor and strong acid-base resistance and chemicals corrosion, improve the performance of Sealing, extended its working life, reduced cost of production.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the Sealing of a kind of anticorrosion antiwear of the present invention;
Fig. 2 is the partial schematic diagram of a specific embodiment of the Sealing of a kind of anticorrosion antiwear of the present invention;
Fig. 3 is the partial schematic diagram of another specific embodiment of the Sealing of a kind of anticorrosion antiwear of the present invention.
The implication of reference character in figure: 1, body, 2, chamfering, 3, L shaped stiffening rib, 4, dust excluder lips, 5, sealing configuration, 6, space, 7, elastic component, 8, arc receiving groove, 9, fillet surface, 10, PTFE layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, the Sealing of a kind of anticorrosion antiwear of the present invention, comprise: the annular body 1 of being made by rubber material, front side and rear side at the outer shroud of body 1 are all formed with chamfering 2, the intensity that guarantees that in order to strengthen the mechanical structure of body 1 it is enough, at body 1, be embedded in L shaped stiffening rib 3, L shaped stiffening rib 3 is preferably made by ironware.As shown in Figures 2 and 3, the interior hoop front side of body 1 and rear side extend to form respectively dust excluder lips 4 and sealing configuration 5.Wherein, dust excluder lips 4 be obliquely installed and and body 1 between be provided with a fillet surface 9, the leading portion of dust excluder lips 4 is concordant with the end of body 1, has optimized dustproof and leakproofness.And between sealing configuration 5 and the outer shroud of body 1, there is a space 6, the interior next-door neighbour's sealing configuration 5 in space 6 arranges an elastic component 7, preferred elastic component 7 is spring, further improved sealing effect, as a kind of concrete structure, the one side that sealing configuration 5 is adjacent with body 1 outer shroud is formed with arc receiving groove 8, and described spring is arranged in arc receiving groove 8.
As further improvement, in order to prevent dry grinding, to reduce frictional force and friction factor and strong acid-base resistance and chemicals corrosion, improved the performance of Sealing, extend its working life, a kind of embodiment as shown in Figure 2, the surface of body 1 at least covers PTFE (teflon) layer 10 at sealing configuration 5 places.As another kind of specific embodiment, as shown in Figure 3, the whole surface of body 1 all covers PTFE layer 10.Mostly adopted in the past gluing mode that PTFE layer 10 and body 1 are combined, complex process, and the dead angle (as bending, corner) that inevitably existence cannot post, and the present invention, creatively adopt PTFE liquid to be sprayed at body 1 surface, then put into baking oven and dry, PTFE layer 10 is just incorporated on body 1 securely, and fast and easy is without dead angle.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
