<p>The present invention provides a valve opening and closing device of a pipeline for a ship to supply electric energy to each valve for opening or closing each pipe of a pipeline arranged on the deck of a ship using a solar cell in order to open or close the pipe. To achieve this, the valve opening and closing device of a pipeline for a ship comprises: the solar cell mounted on the top of each pipe installed with a valve to convert solar energy to electric energy to supply it; an electric supply cable to supply the electric energy of the solar cell to a solenoid valve arranged in the valve; and a signal cable connected to a control panel to receive or transmit a control signal for controlling the operation of the control panel in order to open or close the valve. Therefore, the valve opening and closing device of a pipeline for a ship can reduce the overall electricity consumption of a ship; and can significantly reduce a cable amount without the use of an electrical cable connected to the solenoid valve of the valve and the control panel.</p> |
