Abstract
The utility model belongs to the technical field of hydraulic and pneumatic sealing pieces, in particular to a piston sealing piece for reciprocating motion, which solves the problems in the prior art that the structure of a traditional sealing piece is single, the complementary performance and pressure stability of sealing material are poor, the service life is short, liquid is leaked and the like. In a piston rod seal with a lip, the sealing elastic body area of the main rod sealing piece is in a W-shaped structural design. Compared with the prior art, the piston rod seal with the lip has the beneficial effects that unique sealing material and geometric shape are adopted, the structure is compact, the overall seal is stable, the sealing performance is good, the friction coefficient is small, excellent anti-extrusion and wear-resistant performance are achieved, and the piston rod seal with the clip is a one-way piston rod seal which is widely applied under a heavy load working condition.
Description
Technical field
The utility model belongs to the hydraulic seal technical field, relates to a kind of to-and-fro motion rod seal part, is specially the rod seal of lip ring mouth.
Background technique
The common structure of existing piston shaft seal comprises Y shape circle, flower bud shape circle, U-shaped envelope etc., and its major defect is problems such as structure is single, surface friction drag is big, working life is low, poor sealing performance.
Summary of the invention
Problems such as the utility model is single for the structure that solves rod seal part in the prior art, pressure stability is poor, working life is short, leakage provide a kind of rod seal of lip ring mouth.Such sealing configuration compactness, wear-resistant has very high pressure stability under load, the axially locating performance is good, high abrasion, friction factor are low, and no creeping phenomenon, anti-extrusion performance are splendid.
The utility model adopts following technological scheme to realize: the rod seal of lip ring mouth, rod seal main part sealing elastomer zone is a W shape structure.
Main improvement of the present utility model is that all parts adopt unique technology to guarantee the precision and the whole sealing effect of product.Rod seal main part sealing elastomer zone has increased sealing effect for W shape structural design, makes the main lip of rod seal more lasting to the reaction force of piston rod, significantly improves the voltage endurance capability of Sealing and axle; The rod seal of this structural design can resist very high fluid pressure, has long working life.Adopt stable that Sealing described in the utility model can keep-up pressure for a long time, institute produces heating and wearing and tearing when reducing seal ring with piston rod movement, and high pressure causes lip to turn up, and installs simple and conveniently, has prolonged the working life that seals.
The relative prior art of the utility model has following beneficial effect: adopted unique sealing material and geometrical shape, compact structure, overall stability, good seal performance, friction factor are low, having good anti-extruding and wear-resisting property, is a kind of single acting piston rod seal that is widely used under the severe duty.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, rod seal main part, 2, W shape structure.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.
The rod seal of lip ring mouth, the sealing elastomer zone of rod seal main part 1 is a W shape structure 2, has increased sealing effect.The utility model can be applicable to have anti-high pressure, high abrasion, advantages such as good sealing effect on the piston rod of hydraulic jack.
