本発明は調節弁などの微少開度における弁の制御力法に

ぴｔ量調節をおこなうという方法がとられてい九。Conventionally, when it is necessary to use a control valve to a minute opening degree, a so-called child valve for a small wrench has been used as a parent-child valve. Normally, it is relatively easy to adjust the flow rate within a relatively large range of valve opening, and the fluid flows in proportion to the area of the valve opening, but as the valve gradually narrows down, Due to the shape of the partitioning surface of the valve and the shape of the end face of the valve body, ie, the edge effect, etc., the fluid flows in proportion to the flow rate mr* of the valve as fc, which shows an irregular flow, and therefore the slight opening of the valve. It is difficult to accurately adjust the flow rate in the degree range, so one way to solve this problem of minute opening adjustment is to use a parent-child valve system9. In a relatively large adjustment range, the master valve makes the adjustment, and in the minute adjustment range, the master valve is closed), and the child valve adjusts the amount of pit.

の制御方法を提供するものである。The present invention has been made in order to solve the above-mentioned problem of valve adjustment in the fine adjustment range of the valve. Opening/closing is performed by controlling the opening at a minute opening, that is, 0N-OFF control with a pulse width that is generated continuously and intermittently throughout the valve body above a certain opening. When opening and closing the valve body of m] fully controlled,
The present invention provides a control valve control method that improves the control characteristics of the control valve in a minute adjustment range by adjusting the average flow rate of fluid per hour.

The figure is a control system diagram of a control valve that implements this control method.
l is a sensor receiver and a detector to be controlled (not shown)
The NFC converts state quantities to be controlled, such as temperature, liquid level, and fluid flow rate, into signals that can be calculated. This signal is sent to the controller No. 2, and the given control target value (S
The output is then sent to the next signal switch 3 as a control valve opening signal. The controller 2 sends out each valve opening instruction number, but in this case, the control valve 7 is set to the specified opening T'L specific to that valve, that is, the valve body is opened and closed at the position of the control valve 7. If the opening/closing degree of the valve is required to exceed the boundary point where the opening/closing is controlled by the pulse width in the range where the nffL amount is controlled and the minute adjustment range, the signal switch 3 changes the output of the controller 2. The signal is selected, and the valve opening control device 6 controls the regulating valve 7 to maintain a predetermined valve opening to ensure a fluid flow rate corresponding to the valve opening. Next, when the valve opening command signal from the controller 2 falls within the valve minute adjustment range, the monitor switch 5 is activated, and the valve opening command signal to the controller 9P7 is output from the analog/pulse width converter 4. Switch to the side. In this converter 4, the valve opening degree signal is converted into a pulse signal having a width proportional to the value of the valve opening degree signal (ft-s), and this pulse signal is continuously emitted. In other words, the integral value of the pulse signal for one leg time is a value proportional to the value of the valve opening degree signal.This continuous pulse number 1g is sent to the control valve 7 via the number 1u switch 3, and the 14-section valve The valve element 7 is continuously opened and closed by the valve opening control device 6 corresponding to the width of the pulse signal. Mt is proportional to the pulse width of the circular flow rate of the fluid passing through the valve body for a certain period of time, that is, the value of the valve opening signal.
The storm is secured.

することができるものである。FIG. 2 shows the relationship between the above-mentioned valve opening signal, the valve body position control range, the pulse width control range, and the control output, that is, the amount of fluid flowing through the control valve 7.
The fine adjustment range of the control valve, which is the control range based on this nozzle width, is determined by the MINCM value of the valve. In the position type control region of the control valve 7, a control signal proportional to the value of the valve opening signal is sent to the control valve 7. In the control region, pulses having a width proportional to the valve opening signal are continuously sent, so that the control valve 7 can ensure an accurate time-averaged flow rate according to the valve opening signal even in the minute adjustment range. /bO As explained above, the control force method of the control valve according to the present invention is capable of completely closing the flow rate with a single valve, instead of the conventional parent-child valve system in which fine #I adjustment of the flow rate is performed. Fully open position 1k from the position corresponding to
It is possible to accurately adjust the flow rate up to the full opening range of the valve.
