Description
Technical field
This utility model is related to a kind of valve, particularly a kind of three-eccentric-butterfly-valve.
Background technology
Three-eccentric-butterfly-valve deviates flap center and valve body center for valve rod axle center simultaneously, and sealing pair is the butterfly valve of oblique cone,
By the cooperation of sealing surface of valve plate and valve body valve pocket sealing surface, realize damming.The defect of existing three-eccentric-butterfly-valve is: one is valve
Plate, valve body position are relatively fixed, and cannot be adjusted according to the mated condition of sealing surface of valve plate and valve body valve pocket sealing surface, no in use
Method passes through the uniformity of regulating guarantee sealing surface of valve plate and the cooperation surrounding of valve body valve pocket sealing surface, and sealing reliability is poor；Two are
Pumped (conveying) medium easily leaks at valve rod with Lower shaft sleeve inner hole, and resistance to pressure is poor.
Content of the invention
This utility model is directed to the deficiencies in the prior art, and proposing one kind can significantly improve sealing reliability, can solve to convey
Medium easily leakage problem at valve rod with Lower shaft sleeve inner hole, significantly improves the convenient regulating type three-eccentric-butterfly-valve of resistance to pressure.
This utility model is achieved through the following technical solutions technical goal.
Convenient regulating type three-eccentric-butterfly-valve, including valve rod, valve plate, valve body, Upper shaft sleeve and Lower shaft sleeve；Described Upper shaft sleeve, Lower shaft sleeve
It is separately positioned on valve body upper and lower part；Described valve rod is bearing on valve body by Upper shaft sleeve setting up and down, Lower shaft sleeve；Under described
Axle sleeve bottom is provided with end cap, and end cap is fixedly connected on valve body lower end face；It thes improvement is that: is provided with spiral shell in the middle part of described end cap
Nail, screw thread connects and runs through end cap, and its upper surface is resisted against valve rod lower surface, constitutes valve plate governor motion；Described lower axle
Stem surface in set endoporus is interval with annular groove, is provided with sealing ring in annular groove, constitutes radial shaft seal structure.
In said structure, between described stem lower portion, screw upper surface on have plane bearing, pad；Described plane
Bearing is sleeved on valve rod lower end, and its lower surface is bearing on pad upper surface, and pad lower surface is bearing in screw upper surface.
In said structure, the stem surface in described Lower shaft sleeve endoporus is interval with twice annular groove, is provided with sealing in annular groove
Circle, constitutes double radial shaft seal structure.
In said structure, the part that described screw stretches out end cap lower surface is provided with fastening screw nut, and fastening screw nut is threaded
On screw, it is pressed on end cap lower surface.
This utility model compared with prior art, has the positive effect that:
1st, it is provided with screw in the middle part of end cap, constitutes valve plate governor motion, sealing surface of valve plate and valve can be ensured by adjusting screw
The uniformity of the cooperation surrounding of body valve pocket sealing surface, significantly improves sealing reliability.
2nd, the stem surface in Lower shaft sleeve endoporus is interval with annular groove, is provided with sealing ring in annular groove, constitutes radial axle sealed knot
Structure, can solve pumped (conveying) medium easily leakage problem at valve rod with Lower shaft sleeve inner hole, significantly improve resistance to pressure.
3rd, it is provided with plane bearing between stem lower portion, screw upper surface, on the one hand can reduce valve plate and open and close required torque.
4th, the stem surface in Lower shaft sleeve endoporus is interval with twice annular groove, is provided with sealing ring in annular groove, constitutes dual footpath
To shaft seal structure, improve the reliability of Lower shaft sleeve and valve stem seal further.
5th, screw stretches out the part of end cap lower surface and is provided with fastening screw nut, after screw is adjusted, is pressed on using fastening screw nut
End cap lower surface, can prevent loosening of screw.
