Valve jamming fault monitoring device for hydraulic solenoid valve

The invention discloses a valve jamming fault monitoring device for a hydraulic solenoid valve. The valve jamming fault monitoring device for the hydraulic solenoid valve comprises the hydraulic solenoid valve, a pressure monitoring device, a controller and a power source. The hydraulic solenoid valve is a target monitored article. The pressure monitoring device is used for monitoring the pressurestate of a hydraulic oil way in the hydraulic action circuit controlled by the hydraulic solenoid valve. The hydraulic solenoid valve, the pressure monitoring device and the power source are all connected with the controller. When the controller finds that the valve jamming fault happens through monitoring, the controller outputs the stop instruction to cut off the power source. 本发明公开了种液压电磁阀卡阀故障监测装置，包括液压电磁阀、压力监测装置、控制器和动力源，所述的液压电磁阀为目标监测物，压力监测装置用于监测液压电磁阀所控制的液压动作回路中液压油路的压力状态，液压电磁阀、压力监测装置、动力源均与控制器相连，控制器监测出卡阀故障时，输出停止指令切断动力源。
