Abstract

The invention relates to a hydraulic valve remote control system for ships and ocean equipment, and particularly discloses an electro-hydraulic apparatus, which mainly solves the technical problem that a fault of a valve system needs manual intervention. According to the technical scheme, the electro-hydraulic apparatus comprises an oil tank, a main body structure and a motor chamber, which are successively connected, wherein one side of the motor chamber is provided with an electrical junction box, and the main body structure consists of a bidirectional gear oil pump, an integrated control block assembly and a motor; the output end of the oil tank is connected with the bidirectional gear oil pump, four input ends of the oil tank are respectively provided with a pressure adjusting apparatus A, a pressure adjusting apparatus B, a valve positioner A and a valve positioner B, the pressure adjusting apparatus A is communicated with the valve positioner B, the pressure adjusting apparatus B is communicated with the valve positioner A, the bidirectional gear oil pump is bidirectionally connected with the motor, and the bidirectional gear oil pump is also communicated with the pressure adjusting apparatus A, the pressure adjusting apparatus B, the valve positioner A and the valve positioner B. The electro-hydraulic apparatus is applied to an openness or switch-type rotary motion valve.

Description

technical field [0001] The invention relates to a hydraulic valve remote control system for ships and marine equipment, and in particular discloses an electro-hydraulic device, which is a device for independently providing pressure oil to each valve during the remote control of the valve. Background technique [0002] At present, the domestic hydraulic valve remote control system generally adopts the route from the hydraulic power unit, the solenoid valve box, the hydraulic driver to the valve to realize the remote control of the valve. This situation has some disadvantages: when the hydraulic power unit or the solenoid valve box fails, it may cause all valves in the entire system to be inoperable. The remedial measures that can be taken are generally manual operation with manual hydraulic pumps, and important valves are equipped with single-acting spring return drivers, etc. This will inevitably affect the automatic control of the valve, and even affect the safe operation ...
