Abstract
The utility model belongs to the technical field of hydraulic and pneumatic sealing members, in particular relates to a Y-shaped combined piston rod seal with a support, and solves the problems of single structure, low sealing material complementarity and pressure stability, short service life, liquid leakage and the like of a piton rod sealing member in the prior art. The Y-shaped combined piston rod seal with the support comprises a main annular rod sealing member, wherein a flange is arranged on the inner circumferential surface of the main rod sealing member; and a supporting ring with rectangular section is embedded in the end face on one side of the main rod sealing member, and an O-shaped rubber seal is embedded on the other side of the main rod sealing member. The Y-shaped combined piston rod seal with the support of the utility model is made of a unique sealing material, has a geometric shape, a compact structure, high overall stability and sealing performance, low friction coefficient and superior extrusion resistance and wear resistance and is a one-way piston rod seal which is widely applied to heavy load working conditions.
Description
Technical field:
The utility model belongs to hydraulic pressure, pneumatic seal technical field, is specifically related to a kind of band and supports Y shape combined piston rod seal.
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, 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, sealing material is complementary, pressure stability is poor, working life is short, leakage provide a kind of rod seal of the use under high pressure and low pressure operating mode.Tolerance, compact structure, wear-resistant are stablized, met to such closure size, has very high pressure stability under load, and 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: band supports Y shape combined piston rod seal, the rod seal main part that comprises ring-type, one flange of internal circular surfaces setting of rod seal main part, one side end face of rod seal main part is embedded with the support ring that the cross section is a rectangle, and the opposite side of rod seal main part is embedded with the rubber seal of O shape.
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 pretightening force effect of O shape rubber seal, it is more stable to make sealing embed groove, embedded rectangle support ring makes the lip of rod seal main part obtain better protection, significantly improve rod seal with spool 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 Sealing 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 rod seal 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.
