A riser filling valve with structure and operation state self-checking function

Abstract

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.

Description

technical field

[0001] The invention relates to a riser filling valve with the self-inspection function of structure and operating state, which belongs to the technical field of offshore oil drilling equipment. Background technique

[0002] At present, in the process of deep-sea drilling, the injection valve is one of the main equipments for protecting drilling equipment and pipelines. It has a wide range of applications. Maintenance personnel cannot monitor and manage the operating status and the structural wear and tear of equipment components in a timely and effective manner. As a result, the current daily management of the riser filling valve equipment is very lagging behind, and it is often discovered after the riser filling valve goes out of line. Its operation failure has caused serious equipment hidden dangers to the entire offshore drilling equipment, and it has also caused great difficulties in the fault detection and discharge work of the riser filling valve.
