Abstract
The utility model proposes a kind of fixing ball valve gland flange split type structures, and including valve body, valve rod, the gear-box on the valve body, the valve rod passes through the valve body, and the valve rod is equipped with several sealing rings；The lower gearbox portion is equipped with gland flange, deflector is equipped between the gear-box and the gland flange, when O-ring is worn or is damaged, valve internal medium is leaked along the gap between valve rod and gland flange toward gear-box direction, when by deflector, it is flowed out from its diversion trench, to prevent from entering gear-box.
Description
Technical field
The utility model relates to valve field more particularly to fixing ball valve gland flange split type structures.
Background technique
Sealing element at the fixing ball valve valve rod of gearbox operation is rubber o-ring under normal circumstances, when valve is in operating condition
Upper longer using the time, rubber o-ring is easily damaged or aging, and due to the effect of internal pipe pressure, medium may be along valve
Bar enters inside gear-box, can generate corrosion to gear-box gear or shell.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of fixing ball valve gland flange split type structure, packet
Valve body, valve rod, the gear-box on the valve body are included, the valve rod passes through the valve body, and the valve rod is equipped with several close
Seal；The lower gearbox portion is equipped with gland flange, and deflector is equipped between the gear-box and the gland flange.
Preferably, the deflector includes plate body, and the plate body center is equipped with through-hole, evenly distributed around the through-hole to set
It is equipped at least two diversion trenches.
Preferably, the deflector is equipped with several positioning screw holes, and passing through in the positioning screw hole has locating pin, and fixed
In in the gland flange.
The utility model proposes fixing ball valve gland flange split type structure have it is following the utility model has the advantages that when O-ring wear
Or when damage, valve internal medium is leaked along the gap between valve rod and gland flange toward gear-box direction, by leading
It when flowing plate, is flowed out from its diversion trench, to prevent from entering gear-box.
Detailed description of the invention

Fig. 2 is the bottom schematic view of the deflector of the utility model；
Wherein, 1, valve body；2, valve rod；3, gear-box；4, sealing ring；5, gland flange；6, deflector；7, plate body；8, lead to
Hole；9, diversion trench；10, positioning screw hole；11, locating pin.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in FIG. 1 to FIG. 2, the utility model proposes a kind of fixing ball valve gland flange split type structures, including valve
Body 1, valve rod 2, the gear-box 3 on the valve body 1, the valve rod 2 pass through the valve body 1, and the valve rod 2 is equipped with several
Sealing ring 4, the effect of sealing ring 4 are to prevent the intracorporal cut-off of bottle from flowing out from 2 part of valve rod, improve leakproofness, sealing ring 4 can be set
It sets multiple.
3 lower part of gear-box is equipped with gland flange 5, and deflector is equipped between the gear-box 3 and the gland flange 5
6, wherein the deflector 6 includes plate body 7, and 7 center of plate body is equipped with through-hole 8, evenly distributed setting around the through-hole 8
There are at least two diversion trenches 9, the through-hole 8 of 7 center of plate body setting passes through for valve rod 2, meanwhile, it is equipped on the deflector 6
Several positioning screw holes 10, interior pass through of positioning screw hole 10 has locating pin 11, and is fixed in the gland flange 5, by fixed
Position nail 11 can be fixed by deflector 6, installs quick and convenient.
The working method of the utility model is: when sealing ring 4 is worn or is damaged, valve internal medium is along valve rod 2
Gap between gland flange 5 is leaked toward 3 direction of gear-box, when by deflector 6, is flowed out from its diversion trench 9, thus anti-
Only enter gear-box 3.
A variety of modifications of embodiment will be readily apparent to those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
