It is identical, it further, assembles for convenience, upper connecting base 2 is identical with 3 size of lower connecting base, further, for convenience internally
Portion's flow is shunted and is separated float, underlying measurement chamber 9 and above set measurement 10 connecting pin center of chamber have it is downwardly convex
Diversion rod 15 further in order to avoid impurity outflow, be fixedly connected with metal screen 16 inside top discharge outlet 12, into
One step, operation, the first float 4, the second float 5 and third are measured in order to form an entirety in the underlying intracavitary portion of measurement
6 contact surface of float is the connection plane with angle, and a kind of Three-rotor flow meter with a variety of bindiny mechanisms of the invention is logical
It crosses and opens up interconnected underlying measurement chamber 9 inside glass graduated tube 1 and above set measurement chamber 10, utilize point for measuring intracavitary portion
The water flow inside multiple runners can be measured by setting measurement chamber 10 on body formula float cooperation different location, can also be with
The flow of inlet water inside single runner is measured as needed, so that the functionality and practicability of flowmeter are mentioned significantly
It rises.
Measuring principle：Spinner flowmeter is made of two components, and spinner flowmeter one is gradually expanded from bottom to top
Conical pipe；Spinner flowmeter another is placed in the rotor that can be moved in conical pipe and freely up and down along the center line of pipe.Turn
When measuring the flow of fluid, detected fluid flows into subflow meter from conical pipe lower end, the impact flow of fluid rotor, and it is right
It generates an active force (size of this power changes with uninterrupted)；When flow is sufficiently large, generated active force
By rotor picking-up, and it is allowed to increase.Meanwhile detected fluid flows through the annular section between rotor and taper tube wall, at this moment acts on
There are three power on rotor:Gravity of the fluid to the dynamic pressure of rotor, rotor buoyancy in a fluid and rotor itself.Flowmeter
When right angle setting, rotor c.g. can coincide with Taper Pipe pipe axis, and three acted on rotor power is all along the side for being parallel to pipe axis
To.When these three power reach balance, rotor is just smoothly floated in Taper Pipe on a certain position.For given spinner
Meter, rotor size and shape oneself through determination, therefore its buoyancy and self gravity in a fluid is all to be known to be constant, has stream only
Body to the dynamic pressure of float is changed with the size of incoming flow flow velocity.Therefore when incoming flow flow velocity becomes larger or becomes smaller, rotor will
Make movement upward or downward, the flow section of corresponding position also changes, corresponding speed when flow velocity becomes balance
Degree, rotor are just stable in the new position.The spinner flowmeter given for one, position of the rotor in Taper Pipe and fluid stream
The size of flow through Taper Pipe is at one-to-one relationship.
In order to make rotor, without impinging on tube wall, generally use two methods when the center line of conical pipe is moved up and down：One
Kind is that the heart is equipped with a guiding plug in the rotor, and to keep rotor to move up and down in the center line of conical pipe, another kind is
It is provided with a lot of skewed slot at rotor discs edge, when fluid flows through rotor from bottom to top, on one side around rotor, while again through
Skewed slot generates a propulsive thrust, rotates rotor about central line ceaselessly, so that it may keep rotor that will not encounter tube wall at work.Turn
The rotor material of subflow meter can be made of stainless steel, aluminium, bronze etc..
First float 4, the second float 5 and third float 6 are respectively enterd by diversion rod 15 and set measurement on different
Inside chamber 10.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
