Ship ballast water system

Abstract

The invention discloses a ship ballast water system. The ship ballast water system comprises a hydraulic pipeline and a remote control valve, the hydraulic pipeline is connected to the remote control valve, a hydraulic oil cylinder and a flow meter are further arranged on the hydraulic pipeline, when the remote control valve is opened or closed, part of hydraulic oil in the hydraulic pipeline flows in the hydraulic oil cylinder, the flow meter is in communication with the interior of the hydraulic oil cylinder, and the flow meter is used for measuring and recording hydraulic oil flow in the hydraulic oil cylinder. According to the ship ballast water system, the hydraulic oil cylinder is arranged on the hydraulic pipeline to open or close the remote control valve, the flow meter is further arranged on the hydraulic oil cylinder, the flow of the hydraulic oil in the hydraulic oil cylinder is recorded through the flow meter, and therefore the motion amount of the hydraulic oil cylinder, namely the motion degree of the remote control valve, is calculated to judge the opening and closing position of the valve; and by means of the arrangement mode, large-batch arrangement of immersed cables is omitted, meanwhile, other electric elements are also omitted, and therefore the arrangement cost is reduced, and meanwhile the effect of being free of maintenance and overhaul is achieved.

Description

technical field [0001] The invention relates to the field of ship manufacturing, in particular to a ship ballast water system. Background technique [0002] The ballast water tank of a ship is a hold where ballast water is placed. It is used to adjust the position of the center of gravity, buoyancy and stability of the ship. inappropriate question. Ballast water tanks are usually equipped with a ship's ballast water system to regulate and maintain a steady state of the ship. [0003] The ship's ballast water system consists of ballast water pumps, ballast water pipelines, ballast water tanks and related valve boxes. A hydraulic remote control valve is arranged on the hydraulic pipeline to control the opening or closing of the ballast tank valve. Since it is necessary to record the valve position status of the remote control valve, it is necessary to obtain the indication signal from the valve head. In this case, it is necessary to set up electric components and cables to ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a ship ballast water system in order to overcome the defects in the prior art that the ship ballast water system transmits the valve signal through the cable, which has high requirements on the cable and is difficult to maintain and overhaul, resulting in high cost.
