Intelligent high precision flow control system

Abstract

The invention provides an intelligent high precision flow control system which comprises a system body. The system body comprises a detection module, a flow meter, a control valve and a feedback circuit. The control valve and the detection module are electrically connected with the flow meter through the feedback circuit. The detection module detects a flow signal and transmits the flow signal to the flow meter through the feedback circuit. The flow meter transmits a correction feedback value to the control valve through the feedback circuit operation and processing. The control valve controls the flow value according to the correction feedback value. According to the invention, the detection module feeds back the signal to the flow meter through the feedback circuit to improve the control accuracy and avoid control malfunction, and then send a feedback signal to the control valve to precisely adjust the control valve; through two feedback signals, the control accuracy of the control valve is high; the use of intelligent microcomputers such as a controller is reduced; the cost of industrial production investment is greatly reduced; the flow is accurately controlled; production accidents are reduced; the production efficiency is improved; and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of flow control, and more specifically relates to an intelligent high-precision flow control system. [0002] technical background [0003] The development of flow measurement can be traced back to ancient hydraulic engineering and urban water supply systems. Orifice plates were used to measure the drinking water volume of residents in the ancient Roman Caesar era. Around 1000 BC, ancient Egypt used the weir method to measure the flow of the Nile River. [0004] measurement It is the eye of industrial production. Flow measurement is one of the components of measurement science and technology. It is closely related to national economy, national defense construction, and scientific research. Doing this work well will ensure product quality, improve production efficiency, and promote scientific research The development of technology plays an important role, especially in today's era of energy crisis and increa...

Problems solved by technology

[0005] With the continuous improvement of the level of industrial automation, in the process of industrial production, it is necessary to accurately measure and control the flow and velocity of fluids in various pipelines. , flow measurement, especially the importance of micro-flow measurement is becoming increasingly prominent; in the flowmeter currently used, more sensors are used to transmit detection signals to controllers such as PLC, and the controller directly transmits data after the calculation is completed, and at the same time, the numerical control solenoid valve And control valves, at the same time, intelligent controllers such as PLC have high cost, and a large number of relatively complicated programs are written, which makes the industrial cost very high, which is not conducive to the promotion of industrial automation
