Abstract
The utility model belongs to the technical field of hydraulic and pneumatic sealing elements, in particular to a piston rod sealing element for reciprocating movement. The utility model solves the problems of single structure, poor sealing material complementarity and pressure stability, short service life, liquid leakage and the like of the piston rod sealing element in the prior art. The bud-shaped piston rod sealing element with a lip on a rectangular support ring is characterized in that a sealing elastic body region of a rod sealing main element is in the W-shaped structural design, and the rectangular support ring is embedded in the upper side of the inner circle surface at the axial side. Compared with the prior art, the utility model has the following beneficial effects that the bud-shaped piston rod sealing element adopts unique sealing materials and geometrical shapes, has compact structure, stable whole body, good sealing performance, small friction factor and good anti-extrusion and wear resistance performance, and belongs to the one-way piston rod sealing element widely used under the heavy loading work 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 flower bud shape rod seal of rectangle support ring 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 flower bud shape rod seal of rectangle support ring 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 flower bud shape rod seal of rectangle support ring lip ring mouth, and rod seal main part sealing elastomer zone is a W shape structural design, the inner headed face upside of an axial side embeds the rectangle support ring one.
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 is for to have increased sealing effect for W shape structural design, make the main lip of rod seal more lasting to the reaction force of piston rod, embedded rectangle support ring makes the lip of rod seal main part can access better protection, significantly improve Sealing with the axle concentric and voltage endurance capability; Constitute rod seal with upper-part and made full use of the characteristic that each parts was had, can resist very high fluid pressure, have long working life.Adopt Sealing described in the utility model to improve the harmony of pressurized in the anti-side pressure of sealing and the to-and-fro motion, what can keep-up pressure for a long time is stable, produce heating and wearing and tearing when reducing seal ring and piston rod movement, and high pressure causes lip to turn up, install simple and conveniently, prolonged the working life of sealing.
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.
