The invention discloses one kind can tuning connector and its sealing device, belong to technical field of engineering machinery.It includes mainly joint body, and joint body and sealing hydraulic fluid port cooperation, joint body are equipped with locking nut, be equipped with below the locking nut as described in the claims can tuning connector sealing device；It is described can tuning connector sealing device, include the DO sealing rings of annular, the cross section of the DO sealing rings is the right-angled trapezium on long bottom edge and bevel edge rounded corner.The present invention realizes in 40MPa hydraulic systems below, can sealing of the tuning connector for plane hydraulic fluid port.Present invention is mainly used for the sealings of plane hydraulic fluid port.
Description
Technical field
The invention belongs to technical field of engineering machinery, specifically, more particularly to one kind can tuning connector and its sealing dress
It sets.
Background technology
Generally there are two types of structures for Hydraulic Elements hydraulic fluid port, are divided into SAE flanges hydraulic fluid port and screw thread hydraulic fluid port.The member of SAE flange hydraulic fluid ports
The pipeline and element of part and required connection are required to larger space.Screw thread hydraulic fluid port is divided into as two kinds of structures, and one kind is that angle seals
The hydraulic fluid port of structure, a kind of hydraulic fluid port for plane sealing structure.The hydraulic fluid port of angle sealing has the pipe screw threads made in Great Britain of ISO6149, JISB 2351
The advantages of U.S. standard screw thread hydraulic fluid port of hydraulic fluid port and ISO 11926-1, these hydraulic fluid ports, is good seal performance, the disadvantage is that：It needs special
Cutter, processing cost are excessively high；Angle sealing hydraulic fluid port is all sealed using O-ring.The screw thread hydraulic fluid port of flat seal has ISO 9974-
The advantages of 1 metric system flat seal hydraulic fluid port and flat seal hydraulic fluid port of DIN 3852, these hydraulic fluid ports is not need dedicated tool,
The upper end ream of screw thread goes out a plane, and disadvantage is the increase in the seal request of connecting element, to the seal request of element compared with
It is high.It mainly uses ED planar seal rings and O-ring seal, O-ring seal sealing plane to seal hydraulic fluid port at present, is only applicable to common
Connector is in 16MPa low-pressure systems below；When the seal request to element is higher, it is sealed using ED planar seal rings.
Meanwhile ordinary couplings need larger space, can not be suitable for special small space.Due to O-ring seal and flat seal
The chamfering of screw thread mouth is bonded, and in the high-pressure hydraulic of 16~40MPa, the O-ring seal of compression will produce cut-out risk, together
When the phenomenon that will appear leakage or Micro blazed-grating, influence the Performance And Reliability of product.
Can tuning connector can be used for special small space, but in the hydraulic system of 16~40MPa, due to can tuning connect
Head rest locking nut adjusts the angle of connector, and the support pad below locking nut is equivalent to the plane of ordinary couplings, still
Support pad must with, there are gap, need to move on to moving on to for nut among joint body.ED planar seal rings can not
In-between gap is sealed, so sealing function can not be played.
Invention content
It is an object of the invention to overcome drawbacks described above, provide one kind can tuning connector and its sealing device, realize
It, can sealing of the tuning connector for plane hydraulic fluid port in 40MPa hydraulic systems below.
It is described can tuning connector sealing device, include the DO sealing rings of annular, the cross section of the DO sealing rings is
The right-angled trapezium on long bottom edge and bevel edge rounded corner.
Further, further include support ring, DO sealing rings are set in support ring, the vertical plane and support ring of DO sealing rings
Fit inside.
It is described can tuning connector, including joint body, joint body be equipped with lock with sealing hydraulic fluid port cooperation, joint body
Tight nut, be equipped with below the locking nut as described in the claims can tuning connector sealing device.
Further, the locking nut and support pad can be equipped between tuning connector sealing device.
Further, it is described can long bottom edge and the support pad of DO sealing rings of tuning connector sealing device coordinate.
Further, it is described can tuning connector sealing device DO sealing rings short bottom edge with sealing hydraulic fluid port upper surface
Cooperation.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the short bottom edge of DO sealing rings of the present invention and the upper surface of sealing hydraulic fluid port coordinate, and the pressure realized from inside to outside is close
Envelope；The fillet of DO sealing rings realizes the sealing in gap between support pad and joint body；
2, the fillet of DO sealing rings is contacted with joint body for line, can seal the gap between support pad and connector,
Simultaneously when locking nut and support pad adjust position, it will not make DO sealing rings that overturning deformation or distortion occur and lose
Effect；
3, DO sealing rings of the present invention are not contacted with the chamfering of screw thread or corner angle, avoid what sealing ring was broken by corner angle
Problem is suitable for the sealing of 40MPa high-pressure hydraulics below, can seal the metric system flat seal hydraulic fluid port of ISO 9974-1
And the flat seal hydraulic fluid port of DIN3852.
Description of the drawings
Fig. 1 is the front view of DO sealing rings；
Fig. 2 is the vertical view of DO sealing rings；
Fig. 3 be can tuning connector structural schematic diagram.
In figure, 1, DO sealing rings；2, long bottom edge；3, vertical plane；4, short bottom edge；5, bevel edge；6, fillet；7, joint body；
8, locking nut；9, support pad；10, support ring；11, hydraulic fluid port is sealed.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, can tuning connector sealing device, include annular DO sealing rings 1, the DO sealing rings 1
Cross section be long bottom edge 2 and 5 rounded corner 6 of bevel edge right-angled trapezium.
As shown in figure 3, further including support ring 10, DO sealing rings 1 are set in support ring 10, the vertical plane 3 of DO sealing rings 1
With 10 fit inside of support ring.
As shown in figure 3, can tuning connector, including joint body 7, joint body 7 coordinates with sealing hydraulic fluid port 11, joint body
7 are equipped with locking nut 8, the lower section of the locking nut 8 be equipped with it is above-mentioned can tuning connector sealing device；Locking nut 8 with can
Support pad 9 is equipped between tuning connector sealing device；The long bottom edge 2 of DO sealing rings 1 coordinates with support pad 9；DO is sealed
The short bottom edge 4 of circle 1 and the upper surface of sealing hydraulic fluid port 11 coordinate.
In the use of the present invention, the outer rectangular end that the short bottom edge 4 of DO sealing rings 1 is constituted with vertical plane 3, seals by introversion
Outer pressure.High-voltage oil liquid penetrates into the inside of DO sealing rings 1, the external square of compression DO sealing rings 1 from the screw thread of joint body 7
Shape end makes its deformation, to reach sealing effect, for avoiding high-voltage oil liquid from being flowed out from the gap of retaining ring.
6 one end of fillet of DO sealing rings 1, for the gap between seal nipple ontology 7 and support pad 9.High-voltage oil liquid
Screw thread through joint body 7 penetrates into the lower part of DO sealing rings 1, and 6 face deformation of fillet of DO sealing rings 1 can be sealed up and be connect
Gap between head ontology 7 and support pad 9.Since 1 inside of DO sealing rings is fillet 6, belongs to contact structure, locking
When nut 8 and support pad 9 adjust position, it will not make DO sealing rings 1 that overturning deformation or distortion occur and fail.
Meanwhile the fillet 6 of DO sealing rings 1 is not contacted with the screw thread chamfering or corner angle of joint body 7, institute to avoid
DO sealing rings 1 break problem by corner angle, make that it is suitable for the sealing of the very high hydraulic system of pressure.Therefore, the present invention can be with
The metric system flat seal hydraulic fluid port of ISO 9974-1 or the flat seal hydraulic fluid port of DIN 3852 are sealed, and is suitable for 40MPa or less
High pressure sealing.
