Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
It should be noted that " connection " described herein and the word for expressing " connection ", as " being connected ",
" connected " etc. had both included that a certain component is directly connected to another component, and had also included that a certain component passes through other component and another portion
Part is connected.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
As shown in Figure 1, it is provided by the embodiments of the present application walk ball flowmeter, when in use, medium is flowed by input channel 1
Enter, by 4 counterclockwise flow of pipe under test, is flowed out later by output channel 2.Medium is full of entire pipeline, including guiding mechanism
7, bead 41 is located in the guiding mechanism 7 in pipeline center, along 44 counterclockwise movement of guide rail.
Inside and outside dielectric separates will not be played the role of guidance bead 41 movement by guide rail 44.
It is provided in this embodiment walk ball flow be calculated as inserting-type flowmeter, the center line of input channel 1 and output channel 2 exists
On same straight line, convenient for the connection with medium pipeline.Meanwhile it removing outside input channel and output channel lap 3, other pipes
The center line of section is in together on horizontal plane, for eliminating the influence of gravity.
Pipe under test 4 removes the pipeline section in input channel and output channel lap 3, and other parts are standard circular arc,
The distance between two photoelectric doors, the first photoelectric door 5, the second photoelectric door 6 can be thus accurately calculated according to angle.
Away from input channel and output channel lap, there are allowances for the position that first photoelectric door 5 is put, for bead
Accelerate, the size of allowance can be in the hope of by calculating.
It is a circuit that guiding mechanism 7 is whole, there is breakpoint shorter at one at controllable gate 11.Guiding mechanism 7 is to be measured
It is laid in pipeline 4 along center line, wherein being leaned on being gradually deviated from center line in certain radian at controllable gate 11 to controllable gate 11
Closely.
As shown in Fig. 2, input channel 1 and output channel 2 have the pipeline section of one section of overlapping, this portions center line is located at same
In one perpendicular, setting overlapping pipeline is in order to allow between input channel 1 and output channel 2 and have an access, if not setting
Overlapping pipeline section is set, bead will move along the rail down always, until outflow measurement pipeline, the data measured in this way are once；
And after being provided with overlapping pipeline section, when bead moves to overlapping pipeline section, after controllable gate 11, input channel 1 is entered, into
And it measures again and again.
The opening when bead moves near at controllable gate 11 of controllable gate 11, enables bead to pass through two guide rail overlay regions,
Come back to starting point.After bead passes through, controllable gate 7 is closed, and prevents the medium in input channel 1 and output channel 2 mutual
Interference.
The track that bead 41 moves is approximately a circle, and bead moves on this approximation circle again and again, every fortune
It is dynamic to read a measurement number once week.
Brief description measurement process: assuming that bead 41, from 7 lower section of controllable gate, which is starting point, bead 41 is passed through
After crossing the acceleration of a distance, speed reaches constant, passes through the first photoelectric door 5 later, and the first photoelectric door 5 collects signal, from
It collects the signal and starts timing, bead 41 passes through the second photoelectric door 6 after a period of time, and the second photoelectric door 6 collects signal, adopts
Collecting the signal timing terminates, and bead 41 has arrived at the controllable gate 11 in output channel 2 later, controllable gate 11 1 in the above process
It is directly in close state, when bead 41 is close to 11 top of controllable gate, controllable gate 11 is open-minded, and bead 41 just traverses to input channel
In 1.After bead passes through, controllable gate 11 is turned off, and bead 41 is in input channel 1, has at this moment been restored to the shape of starting point again
State.This is a period of motion, and move in circles this process.
What the above process measured is 41 run duration of bead, it is known that distance can need in the hope of bead speed to seek flow velocity also
Acquire viscosity adjusted coefficient K 1 and speed correction factor k2, product as Jie of bead speed and adjusted coefficient K (k1*k2)
Mass flow speed, can acquire velocity of medium multiplied by pipeline section product.
Viscosity correction factor and speed correction factor data can determine that specific implementation method is will through a large number of experiments
Proving flowmeter with it is to be measured walk ball flowmeter connect, change the viscosity coefficient or flow velocity of medium, read proving flowmeter and show
It counts and walks ball flowmeter registration.Correction factor under a series of different situations that you can get it after obtaining mass data, by it
As known coefficient.When using walking ball flowmeter, correction factor is selected according to the actual conditions of measurement.
As shown in figure 3, three guide rails are evenly distributed on a circumference from the point of view of the cross section of pipe under test, guide rail with
Angle is 120 degree between guide rail.Support rod and guide rail, pipeline are rigidly connected, for fixing guide rail.The number of support rod without
It needs excessively, is arranged one group every appropriately distance.The diameter of guide rail is smaller, and straight between guide rail because without influencing media flow
Linear distance is less than the diameter of bead, thus small club is limited in movement in guide rail.43 diameter of circumference where the guide rail center of circle will foot
Enough it is greater than the small ball's diameter, to the movement slot milling of bead.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
