Abstract
The utility model relates to a kind of double y-shaped rings with Bidirectional seal structure, it is characterized in that its section is double y-shaped cross-sections that the inverted V-shaped mouth that the V-shaped part on the connection of Y shape bottom with Y shape top is disposed opposite to each other is formed, and the internal diameter side of double y-shaped cross-sections and outer diameter side are inner concave curve；The material of double y-shaped rings is fluorine glue, butadiene acrylonitrile rubber, the third glue of second, chlorine rubber or silica gel, the utility model has the advantages that: in use can two way seal, frictional resistance is small, and compact-sized succinct, installation direction is random, easy to use.
Description
Technical field
The utility model relates to a kind of sealing ring more particularly to a kind of double y-shaped rings with Bidirectional seal structure.
Background technique
The section of y-shaped ring is Y-shaped, and the V-shaped part side end face on section Y shape top forms ring week V-shaped groove.When work according to
The cell wall opened by it is affixed on sealing pair coupling surface, and when male part is with operating rate relative motion, y-shaped ring itself is in machine
Under the effect of the self-tightening of tool pressing force or pressure medium, flexible deformation is generated, and the shape between sealing cell wall and sliding coupling surface
At one layer of sealing liquid film, sealing function is generated, blocks fluid leak path.Since the sealing performance of y-shaped ring is reliable, friction
Resistance is small, movement is steady, resistance to pressure is good and structure is simple, easy for installation, to be widely used in reciprocating dynamic seal device, fits
For the industries such as hydraulic, mechanical, pneumatic.
But the major defect of existing y-shaped ring is: since only a side end face has V-shaped groove, and another side end face is flat
Face is not able to satisfy the needs of two way seal, its installation is especially also paid close attention in use so can only play one-way sealing
Direction.When being intended to realize two way seal using y-shaped ring at present, a pair of of y-shaped ring need to be used, it is opposite to install, but in this way, increase
Sealing ring axial dimension is added, and ring structure is scattered.
How to be improved in existing y-shaped ring structure basis, provides a kind of sealing ring for realizing two way seal
As industry concerned issue.
Utility model content
The main purpose of the utility model is that in view of the above-mentioned problems, being changed in existing y-shaped ring structure basis
Into providing a kind of double y-shaped rings with Bidirectional seal structure.To, reach in use can two way seal, structure is tight
It gathers succinctly, installation direction is random, effect easy to use.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of double y-shaped rings with Bidirectional seal structure, it is characterised in that its section is in the connection of Y shape bottom and Y
Double y-shaped cross-sections that the inverted V-shaped mouth that the V-shaped part on shape top is disposed opposite to each other is formed, and the internal diameter side of double y-shaped cross-sections and outer diameter
Side is inner concave curve.
The material of double y-shaped rings is fluorine glue, butadiene acrylonitrile rubber, the third glue of second, chlorine rubber or silica gel.
The beneficial effects of the utility model are: due to the provision of double y-shaped rings with Bidirectional seal structure, two sides
End face all has ring week V-shaped groove, it can be achieved that two way seal, in particular, the internal diameter side and outer diameter side of double y-shaped cross-sections are indent
Curve keeps sealing ring inner wall shape small in both ends open size, the big indent annular surface of intermediate sizes；Outer wall shape is in both ends
Opening size is big, and the small indent annular surface of intermediate sizes also reduces sealing ring as a result, while guaranteeing two way seal
With the contact area of sealing pair coupling surface, reduce friction, prolong the service life, reduces energy consumption.In practical applications, double Y
Shape sealing ring can be applicable under any working condition of one-way sealing or two way seal, without considering installation direction when use,
Using being quickly and expediently installed.The utility model is compact-sized succinct, easy to make, is suitable for popularization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of double y-shaped rings provided by the utility model；
Fig. 2 is the overhead sectional view of Fig. 1；
Fig. 3 is the schematic diagram of application structure of the utility model.
In figure: 1 pair of y-shaped ring, 1a V-shaped part, 1b inverted V-shaped mouth, 1c internal diameter side, 1d outer diameter side, 2 oil cylinders, 3 is living
Plug.
The utility model is described in detail below in conjunction with drawings and examples
Specific embodiment
Fig. 1-2 shows a kind of double y-shaped rings 1 with Bidirectional seal structure, it is characterised in that its section is at Y shape bottom
Double y-shaped cross-sections that the inverted V-shaped mouth 1b that the V-shaped part 1a on portion's connection and Y shape top is disposed opposite to each other is formed, moreover, double y-shaped cross-sections is interior
Diameter side 1c and outer diameter side 1d is inner concave curve.As can be seen that the end face of the side V-shaped part 1a is ring week V-shaped groove, inverted V-shaped mouth
The end face of the side 1b is the ring week inverted v-shaped groove contrary with ring week V-shaped groove.Two way seal face is consequently formed, realizes in the application
Two way seal.
Further, since the internal diameter side 1c and outer diameter side 1d of double y-shaped cross-sections are inner concave curve, just make double Y shape sealings
The inner wall shape of circle is small in both ends open size, the big indent annular surface of intermediate sizes；Make its outer wall in both ends open size
Greatly, the small indent annular surface of intermediate sizes, thus also reduces the contact area of sealing ring and sealing pair coupling surface, and reduction rubs
It wipes, extends the service life, reduce energy consumption.
The material of double y-shaped rings is fluorine glue, butadiene acrylonitrile rubber, the third glue of second, chlorine rubber or silica gel.
Fig. 3 is application structure of the double y-shaped rings 1 provided by the utility model in the sealing structure of piston 3 and oil cylinder 2
Schematic diagram.
It can be seen that piston 3 needs to carry out two-way in moving back and forth in the device of equipment piston and oil cylinder sealing structure
Sealing, and use double y-shaped rings 1, when work, when piston 3 is towards B to when movement, by the side V-shaped part 1a, the side inverted V-shaped mouth 1b it is close
Sealing end face is sealed, when piston 3 in the opposite direction A to movement when, by the side inverted V-shaped mouth 1b, the side V-shaped part 1a seal face into
Row sealing, thus meets the needs of two way seal.In particular, the inner and outer wall of the two way seal coil is inner sunken face,
The contact area of sealing ring Yu sealing pair coupling surface is also reduced, reduces friction, prolongs the service life, reduces energy consumption.
In practical applications, double y-shaped rings can be applicable under the working condition of one-way sealing or two way seal, when use
It is easy to use without consideration installation direction, it is quick for installation.
The above is only the preferred embodiment of the utility model, not to the shaped materials of the utility model and
Structure makes any form of restriction.It is made by the above technical examples according to the technical essence of the present invention any simple
Modification, equivalent variations and modification, are still within the scope of the technical solutions of the present invention.
