Abstract

The utility model is related to a kind of piston rod seal component, it by:Fairlead, groove, seal, piston rod, secondary lip, O-ring, main lip, back-up ring are constituted.Groove is provided with fairlead, seal is respectively equipped with secondary lip and main lip in groove inside and outside seal, one end of seal is equipped with O-ring, the inner side of the other end of seal is rectangular back-up ring equipped with section, and fairlead is sealed with piston rod by seal.The product structure is simple, it is reasonable in design, due to being respectively equipped with major-minor lip, when high pressure is born, good sealing effect inside and outside seal, seal one end can play the function of pretension equipped with O-ring in low pressure, the leakage of oil will not be caused because pressure is small, the inner side of the seal other end is rectangular back-up ring equipped with section, and seal is extruded when it can prevent high pressure, it is easy to install and use, extend the service life of seal.

Description

A kind of piston rod seal component
Technical field
The utility model is related to a kind of piston rod seal component.
Background technology
At present, existing piston rod seal component for together seal, pressure change repeatedly than it is larger when, seal will be produced Change shape, or even ruptures seal, causes sealing to fail, and oil leak influences normal operation and the service life of machine.
The content of the invention
The purpose of this utility model is to overcome disadvantages mentioned above, there is provided a kind of piston rod seal component, and it mainly solves existing Some piston rod seal components for together seal, pressure change repeatedly than it is larger when, seal will be deformed, or even make close Sealing ruptures, and causes the problems such as sealing failure, oil leak, normal operation of influence machine and service life.This practicality is new The purpose of type be achieved in that a kind of piston rod seal component by:Fairlead, groove, seal, piston rod, secondary lip, O-ring, Main lip, back-up ring are constituted.Groove is provided with fairlead, seal is respectively equipped with secondary lip in groove inside and outside seal With main lip, equipped with O-ring, the inner side of the other end of seal is rectangular back-up ring equipped with section, is oriented to for one end of seal Set is sealed with piston rod by seal.The product structure is simple, reasonable in design, due to being set respectively inside and outside seal There is major-minor lip, when high pressure is born, good sealing effect, seal one end is equipped with O-ring, and the work(of pretension can be played in low pressure Can, the leakage of oil will not be caused because pressure is small, the inner side of the seal other end is rectangular back-up ring equipped with section, and it can It is easy to install and use to prevent seal during high pressure to be extruded, extend the service life of seal.
Brief description of the drawings:
Fig. 1 is a kind of structural representation of piston rod seal component of the utility model.
Fig. 2 is a kind of seal configuration schematic diagram of piston rod seal component of the utility model.
1-fairlead, 2-groove, 3-seal, 4-piston rod 5-pair lip
6-O-ring 7-main 8-back-up ring of lip
Specific embodiment:Describe most preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings, a kind of piston rod is close Sealing by:Fairlead 1, groove 2, seal 3, piston rod 4, secondary lip 5, O-ring 6, main lip 7, back-up ring 8 are constituted.Set in fairlead 1 Fluted 2, seal 3 is respectively equipped with secondary lip 5 and main lip 7, the one of seal 3 in groove 2 inside and outside seal 3 End is equipped with O-ring 6, and the inner side of the other end of seal 3 is rectangular back-up ring 8 equipped with section, and fairlead 1 leads to piston rod 4 Seal 3 is crossed to seal.
