In the industrial processes of the industries such as mining industry, metallurgy, chemical industry, often the flow of solution or liquid preparation detected and controlled, traditional method is to adopt flowmeter to add motorized valve, namely by the flow of the flowmeter tracer liquid flow by motorized valve control liquid, this method is not only invested large but also to requiring the very little process of flow then can't be suitable for.Although numerical control chemicals feeder or dosing pump can be controlled tiny flow quantity, but its principle of work is to control according to demarcating in advance good parameter, output quantity is not actual measured value but a kind of estimated value, when equipment because impure, the fouling of liquid or mechanical reason when causing parameter to change, need again to demarcate, with the larger situation of variation of ambient temperature, the party's rule can't be suitable for for some liquid fluidities, has the limitation on using.
Summary of the invention
The purpose of this utility model provides a kind of Detection ﹠ Controling that integrate, has wider flow measuring and controlling scope, be particularly suitable for the detection of tiny flow quantity liquid, impurities is loosely required, do not require that liquid level is constant, be not subjected to viscosity size and mobile impact, have accuracy of detection fluid flow Detection ﹠ Controling device high, convenient for installation and maintenance.
The structure of the utility model Weighing type flow measuring and controlling device is: comprise frame 3, measuring container 2, power sensor 4 and measurement and control host computer 1, measuring container 2 passes through the power installation of sensors in frame 3 inner tip, the upper end of measuring container is provided with into what manifold solenoid valve 5 entered that circulation road 7, lower end be provided with out manifold solenoid valve 9 and goes out circulation road 11, power sensor 4, enter manifold solenoid valve 5 and go out manifold solenoid valve 9 and link to each other respectively signal transmission with measurement and control host computer.Measuring container 2 dress fluids to be measured 8, fluid to be measured 8 is measured by power sensor 4 in the lump together with measuring container 2, and output liquid is by going out manifold solenoid valve 9 controls, the reduction of the general assembly (TW) before liquid output amount equals.Power sensor 4, enter manifold solenoid valve 5, go out manifold solenoid valve 9 and be connected to measurement and control host computer 1 by wire 12, the signal of power sensor 4 is through the weight that measurement and control host computer 1 is amplified, computing obtains fluid to be measured 8, and this device needs to demarcate before use.
The inwall of described measuring container 2 is lining with anticorrosive coat 13, and the range of the size of measuring container 2 and power sensor 4 is determined by the fluid flow scope of wanting observing and controlling.
The circulation road 7 that enters of described measuring container 2 is that the pipeline 6 that becomes a mandarin does not contact with measuring container with the pipeline 6 that becomes a mandarin that enters manifold solenoid valve 5.
The circulation road 11 that goes out of described measuring container 2 is that outflow tube road 10 is communicated to the frame outer wall with the outflow tube road 10 that goes out manifold solenoid valve 9.
Use principle of the present invention is: the weight of measuring container is by force sensor measuring, and the power sensor output signal is sent into and obtained weight data after measurement and control host computer is processed by amplification, analog to digital conversion, calculating etc., and weight detecting need to be demarcated before use.The control procedure of liquid is: when entering manifold solenoid valve and open, liquid enters measuring container, and measurement and control host computer can entering according to the gravimetric value control liquid of measuring container.The working method that goes out manifold solenoid valve is periodicity, and the output of liquid is then controlled out the opening time of manifold solenoid valve by measurement and control host computer and controlled, and the liquid output amount in the control cycle is the weight reduction of measuring container.
The invention has the beneficial effects as follows: this measure and control device integrates Detection ﹠ Controling, compact conformation, can realize the accurate Detection ﹠ Controling of fluid flow, liquid can be liquid, solution, water, oil plant etc., not only has wider flow measuring and controlling scope, and its substantially not impact of the factors such as liquid body viscosity, flowability and liquid level stabilizing of application, the liquid impurities there is wider requirement, be particularly suitable for the observing and controlling of low flow rate liquid.
