蒸気弁の開閉に係るサーボモータのサーボピスト
ン両側の油圧を検出して電気信号に変換する一対
のマノメータと、これらの信号にピストン受圧面
の面積を乗じる一対の乗算演算器と、これら一対
の演算値の減算を行う比較演算器と、該比較演算
器からの出力信号を表示するＣＲＴ及び自動記録
するプリンタを備えたマイクロコンピユータとに
よつて構成される主蒸気弁開閉力の監視装置。 A pair of manometers that detect the oil pressure on both sides of the servo piston of a servo motor that opens and closes the main steam valve of a steam turbine in a thermal or nuclear power plant and converts it into an electrical signal, and a pair that multiplies these signals by the area of the piston's pressure receiving surface. The main unit consists of a multiplication unit, a comparison unit that subtracts these pair of calculated values, and a microcomputer equipped with a CRT that displays the output signal from the comparison unit and a printer that automatically records the output signal. Steam valve opening/closing force monitoring device.
