Abstract
The utility model discloses a kind of check valve type metering control, it is arranged on the pipeline with check-valves, open aperture on pipeline before and after check-valves and pressure transducer is set, gather pressure, pressure transducer connects single-chip computer control system by pressure transducer connecting line, single-chip computer control system and asynchronous machine connect, and the motor shaft of asynchronous machine is installed in pipeline by check-valves motor shaft connecting key, and check-valves is connected with motor shaft.The beneficial effects of the utility model are: utilize the parts check-valves in existing pipe network system, the check-valves resistance coefficient for fluid is obtained by test and numerical simulation, thus by adding simple parts, more quick, effectively draw the flow flowing through pipeline, thus replace existing effusion meter, more convenient and practical.
Description
Technical field
This utility model relates to a kind of flow measurement, particularly relates to a kind of check valve type metering control.
Background technology
Check-valves is used for pipe-line system, and its Main Function is to prevent medium from flowing backwards, go for the pipeline of various medium
On.Check-valves is arranged on pipeline, becomes one of fluidic component of this complete pipeline.Except being possible to prevent medium to flow backwards it
Outward, check-valves can also be used to control the size of flow.Control flow process be: regulated by asynchronous machine be connected to different
The aperture of the check-valves on step motor realizes the control to flow.While the different opening of regulation check-valves, check-valves
The fluid flowed through is had different resistance coefficients, and this coefficient is unrelated with the fluid velocity flowed through.
Summary of the invention
On the basis of the purpose of this utility model is in existing pipe network the check-valves installed, by check-valves
Front and back increase pressure transducer, and control device, measure with pressure transducer before flowing through check-valves under check-valves angle
The pressure gone up below, draws pressure differential simultaneously, obtains flowing through the flow of check-valves by Single-chip Controlling calculating and output.
Simpler practicality, need not go to install effusion meter specially and measure flow.Its technical scheme is as follows:
A kind of check valve type metering control, is arranged on the pipeline with check-valves, the pipeline before and after check-valves
On open aperture pressure transducer be set, gather pressure, pressure transducer connects single-chip microcomputer control by pressure transducer connecting line
System processed, single-chip computer control system and asynchronous machine connect, and the motor shaft of asynchronous machine is pacified by check-valves motor shaft connecting key
Being loaded in pipeline, check-valves is connected with motor shaft.
The beneficial effects of the utility model are: utilize the parts check-valves in existing pipe network system, by test sum
Value simulation obtains the check-valves resistance coefficient for fluid, thus by adding simple parts, more fast, effectively draws
Flow through the flow of pipeline, thus replace existing effusion meter, more convenient and practical.

Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the present invention, below in conjunction with in the present invention
Accompanying drawing, to invention in technical scheme carry out clear, complete description.
As it is shown in figure 1, check valve type metering control of the present utility model, it is arranged on the pipeline 1 with check-valves 2
On, the pipeline before and after check-valves 2 is opened aperture 3 pressure transducer is set, gather pressure.Pressure transducer is passed by pressure
Sensor connecting line 7 connects single-chip computer control system 6, and the pressure of pressure transducer collection is calculated by single-chip computer control system 6
Pressure differential。
Single-chip computer control system 6 and asynchronous machine 5 connect, and the motor shaft 4 of asynchronous machine 5 is connected by check-valves motor shaft
Key 8 is installed in pipeline, and single-chip computer control system 6 controls the output of asynchronous machine 5, can obtain being connected with motor shaft 4 simultaneously
The aperture of check-valves 2。
The resistance coefficient of check-valves under each aperture is stored in single-chip microcomputer(this coefficient is to obtain according to great many of experiments
Come, and pass through the resistance coefficient of the checking of emulation).
According to different media, single-chip microcomputer selects the Media density stored。
Based on formula, and the value of parameters, the speed of fluid is calculated by single-chip microcomputer。
Based on the speed calculated, and the areal calculation outflow Q of pipeline.And export on display screen, demonstrate
The value of flow.
