Problems solved by technology
The usual servo valve box uses a valve box cover to protect all hydraulic valves and non-seawater resistant components to form a large oil-filled enclosed space. This method is easy to implement, but not easy to maintain; Drain the compensating oil clean, and then remove the valve box cover for maintenance

The invention relates to a unit modularized underwater hydraulic servo valve box. An assembly wiring circuit board is installed on a valve box body, a comprehensive control component and a hydraulic valve group are installed on the assembly wiring circuit board in a sealing mode, the hydraulic valve group is communicated with a hydraulic pipe joint installed on the valve box body, and a hydraulic actuator is installed on the hydraulic pipe joint; a watertight socket and a wiring connector are installed on the valve box body, a signal line of the hydraulic actuator is connected into the valve box body through the wiring connector and connected to the assembly wiring circuit board, and the exterior of the connecting position is isolated from seawater through a sensor signal junction box installed on the assembly wiring circuit board in a sealed mode; a filter component is installed on the assembly wiring circuit board in a sealed mode, a switch valve cover and a control circuit board cover are installed on the filter component, a switch valve is contained in the switch valve cover, and a control circuit board connected to the switch valve and the assembly wiring circuit board is arranged in the control circuit board cover; and a servo valve is arranged in the hydraulic valve group and is connected to the assembly wiring circuit board. The unit modularized underwater hydraulic servo valve box has the advantages of unit modularization, easiness in maintenance, light weight and the like.
Description
technical field [0001] The invention belongs to the field of underwater operation, in particular to a unit modularized underwater hydraulic servo valve box. Background technique [0002] At present, in the field of underwater operations, hydraulic manipulators and hydraulic operating tools are indispensable for underwater operations. In order to drive these hydraulic actuators, the submersible is equipped with a hydraulic valve box. A typical general-purpose underwater working tool—the master-slave servo hydraulic manipulator mainly includes an underwater slave hand, a servo valve box, and a surface master hand operation box, among which the underwater valve box is a key component connecting the slave hand and the master hand. The valve box is a relay station for hydraulic power and control signals. It is necessary to isolate the components in the valve box from seawater and ensure the reliability of the connection. The usual servo valve box uses a valve box cover to prote...
