Description
Technical field
This utility model relates to hydraulic control valve technical field, particularly relates to a kind of hydraulic control ball valve body.
Background technology
Hydraulic valve is used to control the flow direction of fluid in hydraulic system or regulates its pressure and flow, because of
This, the sealing of valve body will directly affect the performance of valve body, the two halves valve body of existing Split ball valve valve body
Connect and use Flange joint more, there is sealing effectiveness when valve interior fluid pressure changes poor, easily produce and let out
The problems such as dew, reduce the service life of valve body, affect the precision of valve body.
Utility model content
Technical problem to be solved in the utility model is: in order to overcome deficiency of the prior art, this practicality
Novel offer one hydraulic control ball valve body.
The technical scheme that this utility model solves its technical problem to be taken is: a kind of hydraulic control ball valve
Body, including symmetrically arranged left half valve body and right half valve body, described left half valve body and the joint face of right half valve body
Being provided with lip seal configuration, described lip seal configuration includes that section is trapezoidal seal groove, described sealing
The width of groove is radially gradually reduced by inside lateral, the dual-side of described seal groove is arranged with multiple
Section is the rib of triangle, and described rib is to the internal extension of seal groove, and rib tilts outside valve body,
Range of tilt angles is 20 °-40 °, and the height of described rib is less than seal groove position, described rib place width
1/3 and more than seal groove position, described rib place width 1/4.
Use the seal groove of trapezium structure, make sealing area be gradually increased from inside to outside, it is ensured that sealing effectiveness is more
Good, made the seal groove of entirety be divided into some by the setting of rib, the lip by coupling similar shape is close
Seal forms it into multistage lip seal configuration, it is achieved multistage protection, improves sealing effectiveness；Rib is outside
Roll centroclinal to valve body of the lip of the most matched lip-type packing, when being squeezed lip to
Open outward, increase the contact pressure with rib, improve sealing effectiveness；The height of rib can not be excessive or too small,
Crossing conference and reduce effective sealing area of lip-type packing, the too small contact area that can reduce with lip reduces to be made
With pressure, reduce sealing effectiveness, therefore, rib height is set to the 1/3 of its place seal groove width to
1/2 best results.
In order to improve sealing property further, described left half valve body is provided with inflow entrance, and described right half valve body sets
Having flow export, the inwall of described inflow entrance and flow export is all equipped with multistage oil guide groove, described oil guide groove is
Section is semicircular annular groove.
The beneficial effects of the utility model are: a kind of hydraulic control ball valve body that this utility model provides, and adopt
Realizing multi-stage sealed by trapezoidal multistage lip seal configuration, sealing ring uses and valve body sealing structure shape
The lip-type packing joined, is installed by interference fit and ensures sealing effectiveness, have good sealing effect, be difficult to let out
Leakage, service life length advantage, improve the overall performance of valve body.

Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in detail.This figure is the schematic diagram simplified, only to show
Meaning mode illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
As Figure 1-3, a kind of hydraulic control ball valve body of the present utility model, including a symmetrically arranged left side half
Valve body 1 and right half valve body 2, the joint face of described left half valve body 1 and right half valve body 2 is provided with lip packing knot
Structure, described lip seal configuration includes that section is trapezoidal seal groove 3, and the width of described seal groove 3 is radially
Being gradually reduced by inside lateral, it is triangle that the dual-side of described seal groove 3 is arranged with multiple section
Rib 4, described rib 4 extends to seal groove 3 is internal, and rib 4 tilts outside valve body, inclination angle
Degree α scope is 20 °-40 °, and the height h of described rib 4 is less than seal groove 3 position, described rib 4 place
Width d 1/3 and more than described rib 4 place seal groove 3 position width d 1/4.
Described left half valve body 1 is provided with inflow entrance 5, and described right half valve 2 body is provided with flow export 6, described inflow
All being equipped with multistage oil guide groove 7 on the inwall of mouth 5 and flow export 6, described oil guide groove 7 is semicircle for section
Annular groove.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant
Staff can carry out various change and amendment in the range of without departing from this utility model completely.
The technical scope of this utility model is not limited to the content in description, it is necessary to according to claim model
Enclose and determine its technical scope.
