Abstract

The utility model particularly relates to a piston sealing element for fluid-pressure alternating motion, which belongs to the technical field of fluid pressure and air-operated sealing elements. The utility model solves the problems of structural design of the piston rod sealing element, complementarity of sealing materials, high temperature resistance, short service life and liquid leakage and the like in the prior art. The utility model relates to a piston rod packing element, the outer side and the inner side of the periphery direction of the piston rod packing element are provided with flanges, a retaining ring whose cross-section is rectangle is embedded on the upper side of the inner orb on one side of the shaft direction, and the center of the other side on the shaft direction is provided with an O-shaped sealing ring. The utility model adopts special sealing material and geometric shape, which has the advantages of compact structure, excellent integral stability, abrasion and sealing property, low friction, excellent decompression resistance capability, anti-collapse property and abrasion resistance. The piston sealing element is a heavy-load bidirectional piston sealing ring, which is particularly suitable for high pressure, and is generally used on mining industry.

Description

A kind of rod seal part
Technical field
The utility model belongs to hydraulic pressure, pneumatic seal technical field, is specifically related to a kind of hydraulic reciprocating movement rod seal part (TS131B).
Background technique
The common structure of existing piston shaft seal comprises Y shape circle, flower bud shape circle, rod seal, U-shaped envelope etc., and its major defect is that structure is single, the elastomer material is single, sliding-frictional resistance is big, working life low, high pressure resistant, poor sealing performance etc.
Summary of the invention
The utility model is for problems such as the structural design that solves rod seal part in the prior art, sealing material complementarity, high pressure resistant, working life weak point, leakages, provide a kind of under high pressure and low pressure operating mode the heavy duty sealing and the rod seal part of usefulness, such closure size is stablized, is met tolerance, compact structure, resists and extrude damage, wear-resistant, under load, has very high pressure stability, high axially locating performance, extraordinary anti-extrude reliability, high abrasion, low friction, no stick-slip phenomenon, anti-extrusion performance are splendid.
The utility model adopts following technological scheme to realize: a kind of rod seal part, arranged outside flange in the rod seal part circumferencial direction, the inner headed face upside of an axial side embeds the back-up ring that one section arranged is rectangle, axially is provided with the O RunddichtringO in the middle of the opposite side.
Described flange is respectively twice.
Main improvement of the present utility model is that all parts adopt unique turning process to guarantee the precision and the whole sealing effect of product.Seal lip adopts the design of two road flanges to increase sealing effect, and lubrication has been played in the gully in the middle of simultaneously; The pretightening force effect of O shape circle, it is more stable that groove is embedded, and embedded back-up ring makes Sealing produce supporting effect when bearing pressure, prevents that Sealing is extruded, and significantly improves the voltage endurance capability of Sealing; Constitute the characteristic that rod seal has made full use of each parts institute tool with upper-part, can resist very high fluid pressure and allow the bigger gap of extruding, and have the very long life-span.Adopt the utility model to improve the anti-side pressure and the wear resistance of sealing, can bear the sealing medium (liquid, gas) of high pressure for a long time, stop its sealing medium to leak out Seal cage, avoid the friction of high pressure lower seal and cylinder body to produce heating and wearing and tearing, and, high pressure makes seal failure because of causing lip to turn up, install simple and convenient, the operating life that has prolonged seal ring.
The relative prior art of the utility model has following beneficial effect: adopted unique sealing material and geometrical shape, its compact structure, general stability, wear-resisting, good seal performance, low friction have good anti-pressure release ability, anti-extruding and wear-resisting property.Be a kind of heavily loaded bidirectional piston seal ring under the high pressure operating mode of extensive use, especially be fit to high pressure, be used for mine industry more.Alternative existing folder cloth piston seal under the situation that does not change existing groove has changed the boundary that in the past seals GB and nonstandard size simultaneously, adapts to the design of various grooves.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-back-up ring, 2-Sealing, 3-O shape seal ring, 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.
A kind of rod seal part, arranged outside flange 4 in rod seal part 2 circumferencial directions, the inner headed face upside of an axial side embed the back-up ring 1 that one section arranged is rectangle, axially are provided with O RunddichtringO 3 in the middle of the opposite side.Described flange 4 is provided with twice.
The utility model can be applicable to have anti-high pressure, high abrasion, advantage of good sealing effect on the piston rod of hydraulic jack.
Main duty parameter of the present utility model is as follows:
The main application: be used for shoring, standard cylinder and cylinder
Working pressure :≤70Mpa
Reciprocating speed :≤0.5m/sec
Operating temperature :-30 ℃+100 ℃
Working medium: hydraulic oil, emulsified liquid, water
