Abstract
The utility model discloses a lip-shaped sealing ring. The lip-shaped sealing ring comprises an elastic substrate, a strengthening substrate, O-shaped supporting rings and retaining rings, wherein the elastic substrate consists of a sealing lip and a strengthening ring which form an integrated structure, the cross section of the strengthening ring adopts an L-shaped structure and is connected with a middle point of the outer surface of the sealing lip, wedge-shaped strips are arranged on the inner surface of the sealing lip, and an interval between every two sealing strips is 3-5 mm; the strengthening substrate is covered with the elastic substrate, and the cross-sectional area of the strengthening substrate is 1/4-1/2 of that of the same position of the elastic substrate; the O-shaped supporting rings are embedded in outer surfaces of two ends of the sealing lip; and the retaining rings are embedded in end surfaces of two ends of the sealing lip. The lip-shaped sealing ring has an effective supporting and guiding effect on parts such as a shaft and the like while having the characteristics of simple structure and mounting space saving, and can perform multi-level sealing on equipment, so that the sealing performance is greatly improved, and the use performance and the operation stability of the equipment are greatly improved.
Description
Technical field
The utility model relates to a kind of lip-type packing, belongs to Sealing technical field.
Background technique
At all kinds of breaks, in the machinery such as axle part, often need to seal its connection part, the main elaxtic seal of Sealing and rigid support material form, by guide ring (band) and Sealing, formed, in actual use because of mounting point, friction, the factors such as corrosion and natural aging, very easily cause sealing part abrasion weathering serious, easily there is leakage of oil or dust and enter machinery inside, thereby cause the infringement to equipment, in order to overcome this problem, the normal method adopting is often to change Sealing, but so operation has affected the continuity of equipment operation greatly, and increased operating cost.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, and a kind of lip-type packing is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of lip-type packing, described lip-type packing is by elastic substrate, strengthening base material, " O " type bracing ring and back-up ring form, described elastic substrate consists of sealing lip and strengthening circle and is integral type structure, wherein strengthen ring cross-section for " L " shape structure, with in sealing lip outer surface, point out and be connected, described sealing lip internal surface arranges wedge-shaped bar, described Stamping Steel Ribbon spacing is 3 millimeters-5 millimeters, described strengthening base material is coated on elastic substrate inside, its cross-section area is 1/4-1/2 of elastic substrate co-located cross-section area, described " O " type bracing ring is embedded in sealing lip two ends outer surface, described back-up ring is embedded in sealing lip two ends end face.
Strengthening base material material is fluorine rubber, and back-up ring material is teflon, and it is alloy that " O " type supports material.
The utility model is when having saving installing space characteristic simple in structure, also can play effective support guide effect to parts such as axles, and can carry out equipment multi-stage sealed, thereby sealability is promoted greatly, and extended greatly equipment usability and connect operation stability.
Accompanying drawing explanation
Fig. 1 is this new structure schematic diagram.
Embodiment
As shown in Figure 1, a kind of lip-type packing, described lip-type packing is by elastic substrate 1, strengthening base material 2, " O " type bracing ring 3 and back-up ring 4 form, described elastic substrate 1 consists of sealing lip 5 and strengthening circle 6 and is integral type structure, wherein strengthening circle 6 cross sections are " L " shape structure, with in sealing lip 5 outer surfaces, point out and be connected, described sealing lip 5 internal surfaces arrange wedge-shaped bar 7, described Stamping Steel Ribbon 7 spacing are 3 millimeters-5 millimeters, described strengthening base material 2 is coated on elastic substrate 1 inside, its cross-section area is 1/4-1/2 of elastic substrate 1 co-located cross-section area, described " O " type bracing ring 3 is embedded in sealing lip 5 two ends outer surfaces, described back-up ring 4 is embedded in sealing lip 5 two ends end faces.
