Abstract

The utility model belongs to the hydraulic and pneumatic seal technical field and specifically relates to a single-flange Y-shaped piston rod. The single-flange Y-shaped piston rod solves the problems of the prior piston rod seal which has a single structure, a weak sealing material complementarity, bad pressure stability, a short service life and liquid leakage, etc. The single-flange Y-shaped piston rod seal comprises a ring-shaped rod seal main member the inner circular surface of which is respectively provided with a flange. A supporting ring the section of which is rectangular is embedded in one side end face of the rod seal main member the other side end face center of which is provided with a V-shaped groove. The utility model which adopts unique seal materials and a geometrical shape has the characteristics of compact structure, general stability, good sealing performances, low friction coefficient, excellent extrusion resistance and outstanding abrasion resistance. The utility model which is a single-flange piston rod seal widely applied in a heavy-duty working condition can be applied in the piston rod of a hydraulic cylinder. Furthermore, the utility model has the advantages of high pressure resistance, high abrasion resistance and good sealing effects, etc.

Description

The rod seal of single 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 single 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 single flange Y shape, the rod seal main part that comprises ring-type, the internal circular surfaces of rod seal main part is respectively arranged with flange one, 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.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, rod seal main part, 2, support ring, 3, V-shaped groove, 4, flange
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 single flange Y shape, the rod seal main part 1 that comprises ring-type, the internal circular surfaces of rod seal main part 1 is provided with flange 4, and it is the support ring 2 of rectangle that the side end face embedding of rod seal main part 1 has the cross section, is provided with V-shaped groove 3 in the middle of the opposite side end face of rod seal main part 1.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.
