Embodiment Construction

[0012] The present invention is described below in conjunction with accompanying drawing.

[0013] as attached figure 1 As shown, a high-precision flow valve control system described in the present invention includes a precision pressure regulating valve, a flow control valve, a high-precision flow meter and a control module. The flow medium passes through the precision pressure regulating valve, the flow control valve and the high-precision A flow meter; the control module receives feedback signals from the precision pressure regulating valve, the flow control valve and the high-precision flow meter, and controls the precision pressure regulating valve and the flow control valve.

[0014] The precision pressure regulating valve is used to ensure the precision flow stability required by the system. If the flow accuracy needs to be further enhanced, the temperature of the entire system including the internal flow medium can be subjected to constant temperature treatment; The f...

Abstract

The invention discloses a high-precision flow valve control system. The high-precision flow valve control system comprises a precision pressure regulating valve, a flow control valve, a high-precisionflow meter and a control module, a flow medium sequentially passes through the precision pressure regulating valve, the flow control valve, and the high-precision flow meter, the control module receives the feedback signals of the precision pressure regulating valve, the flow control valve, and the high-precision flow meter and control the precision pressure regulating valve and the flow controlvalve, the closed-loop control system is formed, the mutual feedback of the signals is achieved so as to adjust the valve conveniently, and the control accuracy is improved; and the flow control valveachieves the automated control of the flow through the opening degree of a control valve and the opening and closing frequency, the tedious adjusting operation is avoided, the accuracy of flow control is ensured, and the high-precision flow meter reviews the passing flow medium so as to ensure the requirements of the flow accuracy.

Description

technical field [0001] The invention relates to the technical field of flow control, in particular to a high-precision flow valve control system. Background technique [0002] Most of the existing flow control valves control the flow of the medium through the opening of the valve, the control accuracy is low, and in the flow control process, the opening of the valve needs to be adjusted continuously, the operation is cumbersome and the efficiency is low. low. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a high-precision flow valve control system. [0004] The technical solution of the present invention is realized as follows: a high-precision flow valve control system, including a precision pressure regulating valve, a flow control valve, a high-precision flow meter and a control module, and the flow medium passes through the precision pressure regulating valve and the flow control ...
