Abstract

The utility model belongs to the technical field of hydraulic and pneumatic sealing elements, and particularly relates to a double-flange Y-shaped piston rod seal, aiming at solving the problems of singular structure, poor complementarity of sealing materials, poor pressure stability, short service life, leakage, and the like of the sealing element for the piston rod in the prior art. The double-flange Y-shaped piston rod seal comprises an annular rod-sealing main member, wherein the surface of the inner circle and the surface of the outer circle of the rod-sealing main member are respectively provided with a flange, a support ring with a rectangular section is inlaid in the end face of one side of the rod-sealing main member, and the middle of the end face of the other side of the rod-sealing main member is provided with a V-shaped groove. Due to the adoption of peculiar sealing materials and the geometrical shape, the double-flange Y-shaped piston rod seal has compact structure, stable integral performance, good sealing performance, low friction coefficient, excellent extrusion resistance and abrasion resistance, and is the unidirectional seal for the piston rod, which is widely used under the heavy-load working condition. The double-flange Y-shaped piston rod seal can be applied to the piston rod of a hydrocylinder and has the advantages of high pressure resistance and abrasion resistance, good sealing effect, and the like.

Description

The rod seal of double flange Y shape
Technical field:
The utility model belongs to hydraulic pressure, pneumatic seal technical field, is specially the rod seal of a kind of double flange Y shape.
Background technique:
The common structure of existing piston rod seal comprises Y shape circle, flower bud shape circle, rod seal, U-shaped envelope etc., and its major defect is problems such as structure is single, the elastomer material is single, sliding-frictional resistance is big, working life is low, anti-high pressure difference.
Summary of the invention:
The utility model is problems such as the structure of rod seal is single in the prior art, sealing material is complementary, pressure stability is poor, working life is short, leakage in order to solve, and a kind of rod seal of the use under high pressure and low pressure operating mode is provided.This sealing structure dimensionally stable, meet tolerance, compact structure, wear-resistant, have very high pressure stability under load, the axially locating performance is good, friction factor is low, and no creeping phenomenon, anti-extrusion performance are splendid.
The utility model adopts following technological scheme to realize: the rod seal of double flange Y shape, the rod seal main part that comprises ring-type, the interior circle and the outer round surface of rod seal main part are respectively arranged with flange, it is the support ring of rectangle that the one side end face embedding of rod seal main part has the cross section, is provided with V-shaped groove in the middle of the opposite side end face of rod seal main part.
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.The gully that forms between the flange of rod seal main part internal circular surfaces and the main lip can store a spot of liquid medium and reach the effect that reduces the main lip operating temperature of sealing, reduces friction factor; The design of V-shaped groove makes the main lip of rod seal more stable to the followability of piston rod, and embedded rectangle support ring makes the lip of rod seal main part obtain better protection, significantly improve Sealing with the axle concentric and voltage endurance capability; The rod seal that constitutes with upper-part has made full use of the characteristic that each parts was had, and can resist very high fluid pressure, has long working life.Adopt rod seal described in the utility model to improve the anti-side pressure of sealing and the harmony of rod seal pressurized in to-and-fro motion, what can keep-up pressure for a long time is stable, produce heating and wearing and tearing when reducing sealing with 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.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.
