본 발명은 ON-OFF 밸브의 메인터넌스의 작업 효율을 향상시키는 것을 과제로 한다. 밸브 메인터넌스 지원 장치는, ON-OFF 밸브에 조작기 공기를 공급하는 전자 밸브를 개방 상태로 하는 개방 신호를 취득하는 전자 밸브 개방 신호 취득부(2)와, 전자 밸브 개방 신호 취득부(2)가 개방 신호를 수신했을 때에, 개방 신호의 출력 대상의 전자 밸브에 대응하는 ON-OFF 밸브에 설치된 조작기 압력 계측부(3)로부터, 조작기 공기의 압력 계측치를 취득하는 조작기 압력 취득부(4)와, 압력 계측치를 기억하는 조작기 압력 기억부(5)와, 압력 계측치가 규정치에 도달하지 않은 경우에, ON-OFF 밸브의 조작기에 공기의 내통 누설의 가능성이 있다고 판정하는 내통 누설 판정부(6)와, 내통 누설 판정부(6)의 판정 결과를 제시하는 판정 결과 제시부(7)를 구비한다. The present invention addresses the problem of improving the maintenance efficiency of a switching valve. A valve maintenance assistance device according to the present invention is provided with: a solenoid valve opening signal acquisition unit (2) for acquiring an opening signal for opening a solenoid valve for supplying operator air to an on-off valve; an operator pressure acquisition unit (4) that, when the solenoid valve opening signal acquisition unit (2) receives the opening signal, acquires a pressure measurement value of operator air from an operator pressure measurement unit (3) provided to an on-off valve corresponding to the solenoid valve to which the opening signal is output; an operator pressure storage unit (5) that stores a pressure measurement value; an internal leakage determination unit (6) that determines that there is a possibility of an internal leakage of air in an operator of the switching valve when the pressure measurement value does not reach a predetermined value; and a determination result presentation unit (7) that presents the determination result of the internal leakage determination unit (6).
