での一連の処理を行なう機構を、本明細書では自動調整
機構と総称する。The suitable pressure difference here is the most preferable pressure difference for the performance of the flowmeter to be exhibited. If the pressure difference between Pl and P2 is too large, the load on the flow control valve 7 will be too large and proper adjustment will not be possible. On the other hand, if the pressure difference is too small, the raw material will not flow smoothly. In this case, the adjustment is
Detect the pressure P1 with a pressure sensor, etc., convert it into voltage or current, and input it into a computer, etc.
Here, the set pressure and the manually applied pressure P1 are compared, a signal (such as a pulse) is generated according to the pressure difference, and this signal is used to move the drive mechanism (for example, a step motor) of the automatic pressure regulating valve 1. . In this specification, a mechanism that combines a pressure sensor, an electronic computer, a signal generator (for example, a pulse transmitter), etc., and performs a series of processes from pressure detection to calculation processing and signal generation is referred to as an automatic adjustment mechanism. collectively.
従って本発明では、調圧用自動調整機構８にて自動調圧
弁１を制御し、圧力Ｐ、を調節することとなる。Therefore, in the present invention, the automatic pressure regulating valve 1 is controlled by the automatic pressure regulating mechanism 8 to regulate the pressure P.

The breath is regulated to a predetermined value by transmitting K and opening and closing the control valve 7.

ることができる。In such a situation, in order to increase the pressure inside the small reactor 6, the value of the pressure P2 is converted into current or voltage, inputted to the back pressure adjustment automatic adjustment mechanism 1o, and set in advance. A signal corresponding to the pressure difference is generated by comparing the pressure, and the drive mechanism of the automatic back pressure valve 5 is actuated by this signal to throttle the back pressure valve 5. To generate the signal here, a signal (number or intensity of pulses, current class, voltage, air pressure, etc.) with an intensity proportional to the difference between the set pressure and the measured pressure is generated at once, and the automatic back pressure valve 5 is activated. However, as long as there is a difference between the set pressure and the measured pressure P, a signal with a constant intensity is generated regardless of the size of the difference, and the automatic back pressure valve 5 is turned by a certain angle to throttle it. It is preferable to repeat this several times and gradually throttle the automatic back pressure valve 5 to increase the pressure. In this case, it is preferable to set the series of automatic operations from measuring the pressure P, generating a signal, and operating the automatic back pressure valve 5 to proceed at a fixed time interval, for example, every 2 to 4 seconds. ~11J/c! It is preferable to adjust the drive mechanism (such as a step motor) that operates the automatic back pressure valve 5 so that the pressure is increased within the range of I. An example of an automatic back pressure valve suitable for such an operation is the one shown in FIG.

に応じて調節弁７へ信号が送られ、この信号によって調
節弁７が緩められて流量が増え、もとの流量に速やかに
回復する。As described above, when the automatic back pressure valve 5 is throttled, the pressure P increases, but at the same time, the flow rate of the raw material supply line 6 tends to decrease. However, this decrease in flow rate is immediately input from the flow meter 2 to the automatic flow rate adjustment mechanism 9, which sends a signal to the control valve 7 according to the difference from the set flow rate, and this signal causes the control valve 7 to loosen. The flow rate increases and quickly returns to the original flow rate.
次に、調節弁７の開度が大きくなると、前述した圧力Ｐ
１とＰ２との差が小さくなシ、これは圧力Ｐ。Next, when the opening degree of the control valve 7 increases, the above-mentioned pressure P
If the difference between 1 and P2 is small, this is pressure P.
の低下となって現われる。しかし本発明では、この圧力
Ｐ１の低下の情報は直ちに調圧用自動調整機構８へ入力
され、ここで設定圧力との差に応じて自動調圧弁１へ信
号が送られ、この信号によって自動調圧弁１が緩められ
て圧力Ｐ１が上昇することとなる。This appears as a decrease in However, in the present invention, information on the decrease in pressure P1 is immediately input to the automatic pressure regulating mechanism 8, which sends a signal to the automatic pressure regulating valve 1 according to the difference from the set pressure, and this signal causes the automatic pressure regulating valve to 1 is loosened, and the pressure P1 increases.
