Description
Technical Field

Background
The underwater valve is a general name applied to all valves of an underwater pipeline. It is suitable for underwater operation and marine working condition.
At present, the underwater valve is mainly applied to the exploitation of offshore oil and natural gas, the applied valve mainly comprises a ball valve, a gate valve, a check valve, a control valve and the like, and the operation mode comprises the following steps: diver operations, underwater robot operations, hydraulic control operations, and the like. Due to the special use environment, the installation of the underwater valve is different from the land, and therefore, the underwater valve is often installed underwater by an integrated device such as a manifold.
At present, the more used integrated devices in marine oil production are as follows: a terminal control manifold, an underwater production control manifold, an underwater Christmas tree, and the like. The underwater gate valve is an indispensable part of the equipment, and is usually installed on the equipment in an integrated manner on land. The driving of the gate valve is basically completed by a hand wheel or a handle, and when the gate valve is operated in shallow water, the whole operation is completed by a diver operating the hand wheel or the handle arranged on the gate valve; when the underwater gate valve is installed beyond the diver's diving depth, it is necessary to operate the gate valve switch by the underwater robot. However, the robot arm of the underwater robot can only operate a valve with low pressure and small diameter. For the high-pressure large-drift-diameter gate valve, because the torque provided by the mechanical arm is very low, when the working pressure of the gate valve is too high and the caliber is large, the gate valve cannot be opened or closed, and therefore, a conventional gate valve driving hand wheel or handle cannot be used in deep water working conditions. In addition, the existing gate valve driving hand wheel or handle cannot be operated by using the underwater robot torque tool because the existing gate valve driving hand wheel or handle is not provided with an interface matched with the underwater robot torque tool.
