Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
As shown in Figure 1, Figure 2 and Figure 4, a kind of volume control device based on aperture principle, including base 8, it is described
The upside of base 8 is circumferentially uniformly distributed six pin tracks 14, and the outside of base 8 is provided with gear wheel 3, on the pin track 14
Side is circumferentially uniformly distributed six blades 1, and the gear wheel 3 and base 8 are coaxial, and the upside of gear wheel 3 is circumferentially uniformly distributed six
A axis pin 2, one end of the blade 1 are connected to axis pin 2, and the pin 4 on blade 1 is arranged in pin track 14, and blade 1 is around pin
Axis 2 rotates, and blade 1 is slided along pin track 14, and the left side of gear wheel 3 is provided with pinion gear 6, and the upside of pinion gear 6 is set
There is adjusting rod 5, gear wheel 3 and pinion gear 6 are intermeshed.
As shown in Figure 1, the downside of the housing 7 is welded with base 8, the upside of housing 7 is welded with upper cover plate 10, it is described on
The upside of cover board 10 is welded with pipeline 9, and the left side of upper cover plate 10 is provided with position-limitting pin 11, is set among the position-limitting pin 11
There is scale 13.
As shown in figure 3, the left surface of the blade 1 is provided with groove 12.
Pipeline, is connected in pipeline by specifically used step first, if first time using the device, it is necessary to carry out flow
Calibration, a proving flowmeter is first connected and accessed in pipeline, opened at adjusting rod to a certain scale, it is first-class that certain is passed through into pipeline
The liquid of value, records the flow value corresponding to scale at this time.Different flows is changed, continues to demarcate, finally obtains certain
The how corresponding scale of a certain flow value of one liquid.After calibration, the proving flowmeter connected in advance is removed, is passed through into pipeline
Liquid, by stirring the i.e. controllable fluid flow flowed through of adjusting rod.If replacing the liquid flowed through in pipeline, stream need to be re-started
Amount calibration.
In actual use, base, housing, upper cover plate and pipeline pass through the structure that is welded as a whole, upper cover plate left side
Two position-limitting pins are welded with, the effect of position-limitting pin is blade is rotated formed center flow channels area change scope from zero
To maximum, there is scale between two position-limitting pins, scale is used for calibrational capacity, and the cylindrical hole and adjusting rod on the left of upper cover plate are concentric
Coordinating and use seal with O ring, adjusting rod is intermeshed with pinion gear by key connection coaxial cooperation, pinion gear and gear wheel,
Gear wheel is concentric with base, and gear wheel can rotate on base, thus with movable vane piece around axis pin rotate, while blade along
Pin track slides.Groove is provided with the inside of each blade, when the center flow channels sectional area that blade is formed reduces, blade can
It is always hexagon so as to fulfill center flow channels in blade groove on the right side of into it.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
