Abstract
The present invention announces a kind of novel flow control valve for reducing cavitation, reducing noise.Valve seat is installed in valve body, is also connected with outlet(discharge) flange and suction flange on valve body;Core bar component and valve deck are installed in the valve body;The throttle orifice with the cooperation of core bar component is provided on the valve seat, one end that throttle orifice and core bar component cooperate is cone wide outside and narrow inside;The core bar component includes core bar and the spool for being fixed on core bar end;The spool includes the multiple arcs blade for being uniformly fixed on core bar end, and the lower end surface of multiple arcs blade is the cone with throttling hole end surface cooperation;Multiple arcs blade is towards same lateral bend, and there are gaps between adjacent arc shaped blade.Since fluid is flowed out from the crescent gap between arc shaped blade, flow is adjusted using single annular gap relative to conventional valve, cavitation generation can be reduced, reduce noise.So compared with prior art, the present invention has many advantages, such as that noise is low, structure is simple, adjusting control not easy to wear, easy.
Description
Technical field
The present invention relates to a kind of control valve, specifically a kind of novel flow control valve for reducing cavitation, reducing noise.
Background technique
Regulating valve is equipment important in industrial pipeline feeding device.Regulating valve be by the displacement of executing agency's push rod,
The orifice size for changing regulating valve, achievees the purpose that adjusting, while it is also the main occurring source of noise.Noise pollution at
For universally acknowledged one of 4 big pollution sources, each state all puts into huge fund noise control, and people propose higher want to noise control
It asks.Regulating valve is often the noise source in pipe-line system, and when pressure difference increases, flow velocity increases, pressure reduction, when pressure drops to centainly
When critical value, air pocket, cavitation are easily caused, and with fluid noise and vibration.Regulating valve flow passage structure is to influence to adjust
The key factor of valve generation noise;It therefore, is necessary to the research of regulating valve structure.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the present invention provides a kind of novel flow control valve.
The present invention is realized with following technical solution: a kind of novel flow control valve, including valve body, is equipped in valve body
Valve seat is also connected with outlet(discharge) flange and suction flange on valve body;Core bar component and valve deck are installed in the valve body;The valve seat
On be provided with core bar component cooperation throttle orifice, throttle orifice and core bar component cooperation one end be cone wide outside and narrow inside;Institute
Stating core bar component includes core bar and the spool for being fixed on core bar end;The spool includes uniformly be fixed on core bar end multiple
Arc shaped blade, the lower end surface of multiple arcs blade are the cone with throttling hole end surface cooperation;Multiple arcs blade is towards same lateral bending
Song, there are gaps between adjacent arc shaped blade.
It is further: the upper surface of the multiple arc shaped blade is in cone wide outside and narrow inside.
During being inserted into the throttle orifice of cone of valve seat, the crescent gap of arc gradually becomes smaller spool, until
It is closed completely, flow from large to small, realizes flow adjustment effect;Equally, spool is from valve seat in departure process, between arc shaped blade
Crescent gap change from small to big, flow also changes from small to big, realize flow adjust.
Since fluid is flowed out from the crescent gap between arc shaped blade, single annulus is utilized relative to conventional valve
Gap adjusts flow, can reduce cavitation generation, reduce noise.So compared with prior art, the present invention have noise it is low,
The advantages that structure is simple, adjusting not easy to wear, easy controls.

Specific embodiment
It is a specific embodiment of the invention below, the present invention will be further described with reference to the accompanying drawings.
As shown in Figures 1 to 4, a kind of novel flow control valve, the lower part of valve body 1 is rounded, and upper part is in oblateness;?
Middle part position is equipped with valve seat 1-1 in valve body 1, is provided with the throttle orifice cooperated with core bar component 3 on valve seat 1-1, throttle orifice with it is upper
End is cone wide outside and narrow inside.Suction flange 1-3 is connected on part under valve body 1, is connected with outlet on valve body 1 on part
Flange 1-2.Valve deck 2 is mounted on 1 upper end of valve body.Core bar component 3 includes core bar 3-1 and the spool 3- for being fixed on the end core bar 3-1
2, core bar 3-1 pass through valve deck 2, and spool 3-2 and throttle orifice are positioned opposite;Spool 3-2 includes uniformly being fixed on the end core bar 3-1
Flexible multiple arcs blade, the lower end surface of multiple arcs blade are the cone with throttling hole end surface cooperation;Multiple arcs
Shape blade is towards same lateral bend, and there are gaps between adjacent arc shaped blade.The upper surface of multiple arcs blade is in circle wide outside and narrow inside
Taper, to improve the elastic and logical oil-proofness of arc shaped blade.
The course of work:
Outlet(discharge) flange 1-2 and suction flange 1-3 is connected and fixed together with conveying pipe main body;By pushing and pulling core bar 3-1
The throttle orifice of cone with movable valve plug 3-2 disengaging valve seat 1-1;When the circle for pushing core bar 3-1 that spool 3-2 is made to enter valve seat 1-1
When the throttle orifice of taper, the moon the gap between teeth that spool 3-2 arc shaped blade is constituted is gradually reduced, and flow is also gradually reduced;When promotion core
When bar 3-1, spool 3-2 exits the throttle orifice of the cone of valve seat 1-1, the moon that the spool 3-2 arc shaped blade during being somebody's turn to do is constituted
The gap between teeth is gradually increased, and flow is also gradually increased;Realize flow adjustment effect.
