Abstract
The utility model discloses a but butterfly valve of balance adjustment, the case that a pair of movable piece constitutes is realized opening and closing through sliding, opens and closes and all compare smoothly, can fine dominant discharge. The utility model discloses a case includes valve rod and a pair of movable piece, and a pair of movable piece deviates from mutually in the draw -in groove or is close to mutually and realizes opening or closing, straight -tooth on the cylinder tooth matching activity piece on the valve rod, and by the the opening and shutting or separate and realize opening or closing of butterfly valve of a pair of movable piece of valve rod control, like this when the butterfly valve is opened, it is inboard that the activity piece slides the draw -in groove, and the fluid can not have the impact to the activity piece at the cavity internal flow after the set time, and the fluid flows more smoothly in the cavity. When the butterfly valve cut out, the activity piece was close to mutually, and rivers are comparatively balanced to the impact of a pair of movable piece, and the valve can fine realization be closed to a pair of movable piece.
Description
Technical field
This utility model relates to a kind of valve, a kind of can the butterfly valve of balance adjustment.
Background technology
In valve technology field, the simple in construction of butterfly valve, use field ratio wide.
The Spool rotating by middle lamellar body of existing butterfly valve realizes on an off, and butterfly valve is beaten
When opening, spool is all the time in runner, and fluid has certain impact when flowing to spool, causes
The vibrations of butterfly valve are relatively big, can produce bigger noise；The fluid of flowing is also had necessarily by spool
Obstruction, fluid sometimes can be caused to produce eddy current in runner, can hinder fluid in runner
Normal circulation.
The spool of butterfly valve is an entirety, realizes opening and closing by rotary spool, closes butterfly
During valve, fluid has the biggest impact to spool, it is more difficult to close butterfly valve, it is impossible to enough well control
The flow of butterfly valve.
Utility model content
The purpose of this utility model be to provide a kind of can the butterfly valve of balance adjustment, a pair activity template
The spool constituted realizes opening and closing by sliding, and opening and closing all ratios smoothly, can be very
Good control flow.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of can the butterfly valve of balance adjustment, include valve body, between the inlet and outlet of valve body be
Chamber, chamber built with spool control butterfly valve on an off, spool with valve body outside handle be connected；
It is characterized in that, have draw-in groove in described chamber, described spool includes valve rod and a pair activity
Sheet, described valve rod is connected with handle, and the pair of activity template deviates from or mutually close in draw-in groove internal phase
Realization opens or closes；One end of described valve rod is provided with Cylinder Gear, and described activity template is provided with directly
Tooth, described Cylinder Gear matches with straight-tooth.
Further having, described activity template includes lamellar body and lug, and straight-tooth is located on lug.
Further having, described lug has groove, described straight-tooth is positioned at the both sides of groove.
Compared with prior art, the beneficial effects of the utility model
Spool of the present utility model includes valve rod and a pair activity template, and a pair activity template is in draw-in groove
Deviate from mutually or open or close near realizing mutually, straight on the Cylinder Gear match activities sheet on valve rod
Tooth, by valve rod control a pair activity template folding or separate realize opening or closing of butterfly valve,
So when butterfly valve is opened, activity template slides into inside draw-in groove, when fluid flows through in chamber not
Activity template can be had impact, fluid is at chamber indoor moveable ratio smoothly.When butterfly valve cuts out, movable
Sheet is mutually close, and the impact of a pair activity template is more balanced by current, and a pair activity template can be good
Realize closing valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is valve core structure schematic diagram of the present utility model.
Wherein, 1. valve body, 2. import, 3. outlet, 4. chamber, 5. spool, 6. handle, 7.
Draw-in groove, 8. valve rod, 9. activity template, 91. lamellar bodies, 92. lugs, 93. grooves, 10. Cylinder Gear,
11. straight-tooth.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figure 1, Figure 2 and Figure 3, a kind of can the butterfly valve of balance adjustment, include valve body
1, it is chamber 4 between import 2 and the outlet 3 of valve body 1, chamber 4 is controlled built with spool 5
The on an off of butterfly valve processed, spool 5 with valve body 1 outside handle 6 be connected；Open in described chamber 4
Have draw-in groove 7, described spool 5 to include valve rod 8 and a pair activity template 9, described valve rod 8 with
Handle 6 connects, and the pair of activity template 9 deviates from draw-in groove 7 internal phase or opens near realization mutually
Or close；One end of described valve rod 8 is provided with Cylinder Gear 10, and described activity template 9 is provided with directly
Tooth 11, described Cylinder Gear 10 matches with straight-tooth 11.
The activity template 9 of the present embodiment includes lamellar body 91 and lug 92, and straight-tooth 11 is located at lug
On 92.The Cylinder Gear 10 of valve rod 8 mates with straight-tooth 11, and valve rod 8 can control activity template 9
Near or deviate from, control the closedown of butterfly valve or open.
Having groove 93 on the lug 92 of the present embodiment, described straight-tooth 11 is positioned at the both sides of groove 93.
The Cylinder Gear 10 of valve rod 8 matches with the straight-tooth 11 of both sides, and valve rod 8 controls activity template 9 and moves
Dynamic comparison is steady.
Spool 5 of the present utility model includes valve rod 8 and a pair activity template 9, a pair activity template 9
Deviate from draw-in groove 7 internal phase or open or close near realization mutually, the Cylinder Gear 10 on valve rod 8
Straight-tooth 11 on match activities sheet, is controlled folding or the separation of a pair activity template 9 by valve rod 8
Realizing opening or closing of butterfly valve, so when butterfly valve is opened, activity template 9 slides into draw-in groove
Inside 7, activity template 9 will not be had impact when fluid flows through in chamber 4, fluid is at chamber
In 4, flowing ratio is smoothly.When butterfly valve cuts out, activity template 9 is mutually close, and current are movable to a pair
The impact of sheet 9 more balances, and a pair activity template 9 can well realize closing valve.
