Description
Technical field
The invention belongs to industrial valve fields, and in particular to a kind of modified butterfly valve.
Background technology
In industrial circle, especially in pipeline medium transportation art, the application of industrial valve is very extensive.Wherein, butterfly
Valve is widely used in gas-solid pipeline system.Butterfly valve is called flap valve, is a kind of disc type opening and closing element reciprocating rotating 0
Closing, unlatching and the valve for adjusting flow are realized to 90 °, there is advantage simple in structure, small, easy to operate, in work
Using very extensive in industry field.Butterfly valve in use, relies primarily on the periphery of valve plate and fitting closely for valve interior wall
It is sealed to realize, but since contact area is small, and the problems such as continuous abrasion, is susceptible to sealed thin weakness on binding face, leads
The case where causing leakage occurs, and influences using effect.
In view of the above problems, applicant carried out research, a kind of butterfly valve of improved good leak-proof effect is provided.
Invention content
Deficiency in for the above-mentioned prior art, the present invention provides a kind of modified butterfly valve, the sealing performance at valve port
It is good, effective leakproof.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals.
A kind of modified butterfly valve, including valve body, the valve body upper end are equipped with upper attachment, and the lower end of valve body is equipped with lower attachment,
Rotatable valve rod enters after sequentially passing through attachment and valve body in lower attachment, and the valve rod is located at the part in valve body and is equipped with use
In being respectively provided with mounting groove on the butterfly plate of opening and closing, the both sides inner wall of the valve body, rotatable air bag component is equipped in the mounting groove,
The air bag component includes the metal expansion pipes of side openings, the pressure bladder in the metal expansion pipe, is stretched set on metal
The connector at draw both ends, the gear on the outside of the connector；The valve rod is equipped with and gear meshed gears disk, the tooth
Wheel disc is rotated with valve rod and is rotated with moving gear.
Butterfly valve in the prior art is generally sealed with hard contact of valve interior wall to realize by butterfly plate, and sealing effect is not
Well, the case where being susceptible to leakage.It is same with the toothed disc on ovable valve stem when valve rod rotation carries out valve opening and valve closing in the present invention
Step rotation, while being rotated with moving gear, and then drive air bag component rotation.When butterfly plate is closed, the pressure bladder in air bag component
It is compressed air on mounting groove, in pressure bladder, pressure bladder protrudes at this time, is bonded the periphery of butterfly plate, has good
Sealing effect；In butterfly plate opening procedure, air bag component rotation, pressure bladder part is transferred to inside mounting groove, metal expansion pipe
Part be located in installation notch, friction damage of the solid in fluid to air bag component can be avoided.Air bag component is bending
Arc is placed in mounting groove, rotation process metal expansion pipe can carry out it is certain draw high and compress, do not influence to rotate.
In present embodiment, the periphery of the butterfly plate is equipped with several fins, specifically, the periphery of butterfly plate is equipped with three
Fin, the oblique fin and intermediate center fin in respectively two outsides, and the height of center fin protrusion is less than oblique fin
The height of protrusion.
During butterfly plate rotates and closes valve, the oblique fin on butterfly plate is first contacted with pressure bladder, by air sac pressing
It into the groove between two oblique fins, then continues to squeeze, surface and the center fin of pressure bladder fit closely, and at this time have
There is good leak preventing effect.
Preferably, the opening angle of the metal expansion pipe side is 80 ° ~ 100 °, preferably 85 ° ~ 90 °, ensure valve opening
Into maximum process, pressure bladder part can be completely into in mounting groove.
Compared with prior art, the invention has the advantages that：A kind of butterfly valve with leak preventing effect is provided, is led to
After the flexible gluing, sealing for crossing pressure bladder and butterfly plate periphery substantially increases sealing performance, while butterfly plate is opened, pressure bladder
Not with the media contact in runner, friction damage is avoided, the service life is high.

Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings.
Referring to Fig.1 to Fig. 9, a kind of modified butterfly valve, including valve body 3,3 upper end of the valve body is equipped with upper attachment 1, valve body 3
Lower end be equipped with lower attachment 5, upper attachment 1 and lower attachment 5 are equipped with mounting hole 11, and rotatable valve rod 2 sequentially passes through attachment 1
Enter in lower attachment 5 with after valve body 3, the valve rod 2 is located at the part in valve body 3 and is equipped with the butterfly plate 6 for being used for opening and closing, valve rod 2
Top is equipped with connector 21, for connecting driving structure, such as wheel disc or bull stick；It is respectively provided with peace on the both sides inner wall of the valve body 3
Tankage, rotatable air bag component is equipped in the mounting groove, and the air bag component includes the metal expansion pipe 41 of side openings, sets
Pressure bladder 4 in the metal expansion pipe 41, set on 41 both ends of metal expansion pipe connector 43, be set to outside the connector 43
The gear 44 of side, specially bevel gear, the connector 43 is ring-shaped structure, convenient for rotation；The valve rod 2 is equipped with and tooth
