Specific embodiment
As shown, a kind of butterfly valve of band guiding, including valve body, valve plate 1 is equipped with by valve rod 2 in valve body, in valve body
Circle surface is provided with sealing ring, it is characterised in that: and 1 fluoran stream surface of valve plate is provided with 6 two flow guide bar 3, lower flow guide bar flow guide bars,
3 middle section of upper flow guide bar of the utility model embodiment one is arched upward upwards, lower 6 middle section of flow guide bar to lower recess, upper flow guide bar 3, under
6 middle section two side portions of flow guide bar constitute diversion section；Butterfly valve implements flowing control in unlatching, closing or by regulating opening angle
When, the interior fluid directed flow for being in valve plate upstream of 6 two upper flow guide bar 3, lower flow guide bar flow guide bar conduits, there is no
Complex flowfield；2 both ends of valve rod are fixedly connected on 1 lee side of valve plate by installation set 4, and 4 two sides of installation set are both provided with oblique add
Strengthening tendons 5, valve rod 4 need not pass through among valve plate 1, and valve board structure is simple, manufacture processing technology conveniently, intensity is high, volume
It is small；The reinforcing rib of installation set two sides may be fluid flow guiding simultaneously, and the fluid oriented flow in valve plate downstream is in conduit
It is dynamic.5 both ends of reinforcing rib and 1 edge of valve plate of 1 lee side of valve plate have a distance, and 5 both ends of reinforcing rib have with valve plate edge
A distance is slightly larger than the intracorporal sealing ring height of valve, and when valve plate 1 is closed, reinforcing rib 5 will not influence the close of sealing ring and valve plate
Seal effect.
Further, upper flow guide bar 3,6 middle section thickness of lower flow guide bar are greater than two sides diversion section thickness, and pipeline fluid is along water conservancy diversion
Section can have certain impact power to middle section when flowing to middle section, and middle section thickness is thicker, and intensity is high, can resist impact force, be not easy to grind
Damage.
Butterfly valve of the utility model embodiment two with guiding, upper 3 middle section of flow guide bar can also be to lower recess, lower flow guide bar 6
Middle section can also arch upward upwards, and pipeline fluid flow to the diversion section of 6 two upper flow guide bar 3, lower flow guide bar flow guide bars along diversion section
To middle part directed flow, it flow between 6 two flow guide bar 3, lower flow guide bar flow guide bar middle sections behind space again respectively along upper water conservancy diversion
The diversion section shunting of 6 two item 3, lower flow guide bar flow guide bars, further decreases mobilization force.
Further, upper flow guide bar 3,6 diversion section of lower flow guide bar are to the intermediate wedge shape successively reduced to both ends, valve plate 1
Lee side reinforcing rib 5 is also the extremely intermediate wedge shape successively reduced to both ends；Further increase diversion effect.
5 both ends of reinforcing rib of butterfly valve of the utility model embodiment three with guiding, 1 lee side of valve plate extend to 1 side of valve plate
Edge, the groove being adapted with 5 shape of reinforcing rib is provided on the intracorporal sealing ring of valve, and 5 thickness of reinforcing rib is greater than depth of groove, valve
When plate 1 is closed, groove on 5 embedding sealing ring of reinforcing rib, and depth of groove is less than 5 thickness of reinforcing rib, reinforcing rib 5 will not shadow
The sealing effect of sealing ring and valve plate is rung, while simplifying valve plate process for machining and manufacturing.
The butterfly valve of the utility model band guiding, by being in valve plate upstream in the flow guide bar conduit of valve plate fluoran stream surface
Fluid directed flow, for butterfly valve in unlatching, when closing or implementing flowing control by regulating opening angle, there is no complexity to flow
, it can reduce noise and vibration, reduce valve plate abrasion, extend butterfly valve service life, improve system run all right；Valve plate back
Stream interface installs connection valve rod by installation set, and lee side fluid flow forces are small, and the reinforcing rib of installation set two sides may be simultaneously
Fluid flow guiding further decreases noise and vibration, reduces abrasion of the fluid to installation set, valve plate.
