Specific embodiment
Make specific introduction to the utility model below in conjunction with the drawings and specific embodiments.
Reference picture 1, Fig. 2 and Fig. 3, anti-lock flue regulating butterfly valve of the present utility model include：Valve body 6, valve rod 10, butterfly plate
8th, drive device 16, upper bracket 13, lower carriage 5, bearing 3, end cap 1, filler 7, filler 11, butterfly spring 21, hold-down grid 19,
Elastic seal ring 24 and pressure plate loop 23.
Butterfly plate 8 is fixed on valve rod 10 by straight pin 9, and valve rod 10 is arranged in valve body 6, and drive device 16 is with ovable valve stem
10 and butterfly plate 8 do gyration, so as to realize switch, the regulatory function of valve.Drive device 16 can be manually, electrically, gas
Move.
The upper end of upper bracket 13 and valve body 6 is fixedly mounted by studs 12 and hex nut 14, lower carriage 5 and valve body
6 lower end separates.The upper and lower ends of valve rod 10 draw valve body 6 respectively, and upper end is through Double-ended nut 15 after upper bracket 13 and drives
Device 16 is connected；Reference picture 5, through installing bearing 3 after lower carriage 5, end cap 1 is arranged on the outer of lower carriage 5 and bearing 3 for lower end
End, and be fixed by hexagon socket head cap screw 2, it is provided between the lower end of bearing 3 and end cap 1 and cap 4.Due under valve rod 10
End is supported by external bearing 3, so reducing the friction between transmission.
Reference picture 4, filler 7, filler 11 use soft graphite, there is some groups, be filled in valve rod 10 and valve body 6 it
Between, butterfly spring 21 is arranged between each group filler, and after filler is finished, hold-down grid 19 pushes down filler 7, filler 11 from outer end,
And hold-down grid 19 is fixedly mounted on upper bracket 13 by studs 20 and hex nut 17, hex nut 17 and filler
Packing ring 18 is provided between pressing plate 19.As a result of new packing seal structure (deep stuffing-box), valve body 6 and valve rod 10 it
Between all isolated by filler so that the contact area of valve body 6 and valve rod 10 is reduced at least, not produce relative motion, so as to shut out
The possibility for being rubbed between valve body 6 and valve rod 10 absolutely, has also just prevented the stuck phenomenon that Relative friction causes, and effectively prevents valve
Bar 10 effective solves the problems, such as that valve rod 10 cannot be opened and closed by whole valve caused by locking by locking.Due to filler
It is point multistage to install, butterfly spring 21 is installed between filler and filler, butterfly spring 21 can compensate in butterfly valve running because
The leakage that filler abrasion causes, so butterfly valve seal of the present utility model is more preferable.Additionally, in the process of running, even if having few
Amount molecule enters in stuffing-box, can also be embedded in lubrication, soft graphite, can't bring abrasion to valve rod 10.
Reference picture 6, elastic seal ring 24 is fixedly mounted on butterfly plate 8 by pressure plate loop 23, and positioned at butterfly plate 8 and valve body
6 contact site.Pressure plate loop 23 is fixedly mounted on butterfly plate 8 by hexagon socket head cap screw 22.
Used as a kind of preferred scheme, reference picture 6, elastic seal ring 24 is formed using intermetallic composite coating, and with flexible
Groove.Elastic seal ring 24 can occur elastic deformation under the effect of medium power, the error in process is compensated automatically and was used
Abrasion in journey, increased actual seal pressure, it is ensured that the high-performance sealed of valve, extend the service life of butterfly valve.Instead
During to sealing, because the axis hole of the axis hole and valve body 6 of valve rod 10 and butterfly plate 8 is all that gap coordinates, sealed under the effect of medium power
The actual ratio pressure in face can be reduced, the deformation of elastic groove can play it is certain make up effect, can be reached in two-way exchange pipeline
Reversely sealing.Compared with other sealing surfaces, the sealing surface of elastic seal ring 24 with elastic groove washes away substantially to the front of medium
It is unaffected.
As a kind of preferred scheme, reference picture 7, the axis of rotation of valve rod 10 deviate valve body 6 sealing surface center line A and
The runner center line B of valve body 6.The two bias can effectively reduce butterfly valve valve body 6 and elastic seal ring 24 in switching process
Between friction.
It is further preferred that reference picture 7, the sealing surface of valve body 6 is in cone shape, and the axis C of the cone is perpendicular to valve
The axis of rotation of bar 10, and rotate deviation with the runner center line B of valve body 6.This bias causes valve body 6 and elastic seal ring
24 completely disengage from during butterfly switch.
Butterfly valve of the present utility model is provided with three bias, both make use of cam effect, and friction is completely eliminated again, realizes
Friction free opening-closing process, eliminates the leakage problem produced by abrasion.
Additionally, the elastic seal ring 24 of butterfly valve of the present utility model and valve body 6 form conical sealing face, butterfly plate 8 from
0 ° to 90 ° when gradually opening, elastic seal ring 24 can immediately depart from the sealing surface of valve body 6 in the moment opened, and butterfly plate 8 is from 90 °
When being progressively closed off to 0 °, elastic seal ring 24 only can just be contacted under completely closed state and compress the sealing surface of valve body 6.Institute
Locking range of taper is not only avoided with butterfly valve of the present utility model, it is to avoid high sealing moment of torsion and the generation for opening moment of torsion high,
And stuck phenomenon is eliminated from geometric angle, the torque needed for ensuring that butterfly switch within whole service life not
Can change.
Because butterfly valve of the present utility model has above-mentioned special structure, so that it can go up time, generally applicable
In operating modes such as flue gas desulfurization, Pneumatic ash conveying, slurries discharges.
It should be noted that above-described embodiment does not limit the utility model in any form, all use equivalents or wait
The technical scheme that the mode of conversion is obtained is imitated, is all fallen within protection domain of the present utility model.
