Abstract
The utility model is related to a kind of extra-high voltages to move back and forth bidirectional hydraulic sealing cup, including rubber bowl bottom, rubber sealing cup side, two coaxial one systems of rubber bowl side backwards to setting are in the both sides of the edge at rubber bowl bottom, form the structure of two way seal, catch bar mounting hole is formed in the middle part of rubber bowl bottom, stainless steel bowl core is formed among the bottom of bowl rubber of sealing cup, bowl core extends inwardly to catch bar mounting hole inner edge, and bowl core extends out to the corresponding position in two rubber sealing cup side roots.Extra-high voltage provided by the utility model, which moves back and forth bidirectional hydraulic sealing cup, plays an important role of two way seal, increases ring stainless steel grommet in the intermediate installation position of sealing cup, can greatly improve the reciprocal motive force of sealing cup tolerance, improves voltage endurance capability.
Description
Technical field
The utility model belongs to sealing element field, and particularly a kind of extra-high voltage moves back and forth bidirectional hydraulic sealing cup.
Background technology
Hydraulic leather cup is mainly used for playing transmission pressure in hydraulic braking system for automobile and clutch operating system, afterburner system
And sealing function.Rubber cup be primarily referred to as applying car, Light-duty Vehicle, minibus, part bogie, including military use
The brake fluid system and clutch operating system of the high-pressure systems such as submarine reinforce to rise in pumping system and transfer pressure and sealing function
Rubber seal.Rubber cup is also applied on household electrical appliance, right such as with the rubber cup on two-tub washing machine cylinder body
Cylinder body plays sealing function.Rubber cup is a kind of in rubber to be widely used one of important rubber product of function.
Leather cup of the prior art is generally directed to the hydraulic system (20- in the such as automobile or household electrical appliance of general applications
50MPa), pressure is smaller in these systems, and general sealing cup can be just competent at, but (the 100- when pressure rise
300MPa), existing leather cup is obviously being subject to larger limitation using upper.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of good airproof performance, structure novel are provided
Extra-high voltage move back and forth bidirectional hydraulic sealing cup.
Technical solution is used by the utility model solves its technical problem：
A kind of extra-high voltage moves back and forth bidirectional hydraulic sealing cup, and including rubber bowl bottom, rubber sealing cup side 4, two same
Axis in the both sides of the edge at rubber bowl bottom, forms the structure of two way seal, at rubber bowl bottom backwards to one system of rubber bowl side set
Middle part is formed with catch bar mounting hole,
Stainless steel bowl core is formed among the bottom of bowl rubber of sealing cup, bowl core is extended inwardly in catch bar mounting hole
Edge, bowl core extend out to the corresponding position in two rubber sealing cup side roots；
There are two sealing bulge loops for rubber bowl bottom outer rim spaced radial system among two rubber sealing cup sides.
Moreover, polytetrafluoro sealing ring is co-axially mounted in the mounting hole inner edge at rubber bowl bottom.
Moreover, the outer rim of the polytetrafluoro sealing ring of the bottom of bowl both sides coaxially extends along rubber bowl bottom to rubber sealing cup side
One section of sealing ring.
The advantages of the utility model and good effect are：
Extra-high voltage provided by the utility model, which moves back and forth bidirectional hydraulic sealing cup, plays an important role of two way seal, close
The intermediate installation position of strip of paper used for sealing bowl increases ring stainless steel grommet, can greatly improve the reciprocal motive force of sealing cup tolerance,
Improve voltage endurance capability.
Extra-high voltage provided by the utility model moves back and forth the obturating cup that bidirectional hydraulic sealing cup is reversed at two
Centre, coaxial spaced system there are two sealing bulge loop, can make further to increase leakproofness between the edge of leather cup and casing wall.
It is poly- that extra-high voltage provided by the utility model moves back and forth the increase in intermediate mounting ring of bidirectional hydraulic sealing cup
Polytetrafluoroethylsealed sealed outer sleeve can further buffer sealing effect during mobile leather cup movement, improve the proof pressure of entire leather cup
Characteristic.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the dimensional structure diagram of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of extra-high voltage moves back and forth bidirectional hydraulic sealing cup, and including rubber bowl bottom 2, rubber sealing cup side 4, two same
Axis in the both sides of the edge at rubber bowl bottom, forms the structure of two way seal, at rubber bowl bottom backwards to one system of rubber bowl side set
Middle part is formed with catch bar mounting hole, and the innovation of the application is：
1st, stainless steel bowl core 3 is formed among the bottom of bowl rubber of sealing cup, bowl core extends inwardly to catch bar mounting hole
Inner edge, bowl core extend out to the corresponding position in two rubber sealing cup side roots, i.e., rubber edge 6 are enclosed on the outside of bowl core,
For being sealed with movement cylinder body.
2nd, the rubber bowl bottom outer rim spaced radial system among two rubber sealing cup sides can make there are two sealing bulge loop 5
Further increase leakproofness between the edge and casing wall of leather cup.
3rd, polytetrafluoro sealing ring 7, the polytetrafluoro sealing of bottom of bowl both sides are co-axially mounted in the mounting hole inner edge at rubber bowl bottom
The outer rim of circle coaxially extends one section of sealing ring 1 along rubber bowl bottom to rubber sealing cup side, forms the sealing to mounting hole.Increase poly-
Polytetrafluoroethylsealed sealed outer sleeve can further buffer sealing effect during mobile leather cup movement, improve the proof pressure of entire leather cup
Characteristic.
