The invention relates to a water insulation
pipe filling valve with a structure and running state self-detection function. The water insulation
pipe filling valve comprises a water insulation
pipe body, a water insulation pipe cabin door, a drive oil cylinder, a balance valve, a main control valve, a lock valve, a
changeover valve, an
energy storage device, travel sensors, a
pressure sensor, an ultrasonic flaw detection device and a detection control device. The main control valve, the lock valve, the
changeover valve, the
energy storage device and the detection control device are all arranged on the outer surface of the water insulation pipe body, the water insulation pipe cabin door is in sliding connection with the water insulation pipe body, the balance valve is additionally embedded in the water insulation pipe body, and the detection control device comprises a
data processing circuit, a drive circuit and a communication circuit. The running state of the water insulation pipe filling valve can be effectively monitored, structure detection can be carried out on the mechanical structure and parts of the water insulation pipe filling valve, and therefore the running monitor capacity to the water insulation pipe filling valve can be improved, hidden fault danger existing in the water insulation pipe filling valve can be found in time, and the running stability and reliability of the water insulation pipe filling valve are improved.
