<p>PROBLEM TO BE SOLVED: To easily perform return operation after excessive flow preventive actuation of an excessive flow preventive valve of a fuel gas vessel by connecting an advance/retreat actuator started and operated from the inside of a cabin with a reset mechanism of the excessive flow preventive valve by a cable or a rod. SOLUTION: An automatic remote control mechanism is constituted by connecting a lever 5 to a reset mechanism of an excessive flow preventive valve 4 and connecting the lever 5 to an advance/retreat actuator 7 arranged on a roof by a cable 6. A solenoid is suitable for the advance/retreat actuator 7, and an air cylinder may be acceptable, and the solenoid is directly connected by wiring to an electric switch arranged in a cabin, and for the air cylinder, a solenoid valve is arranged in air piping for connecting an engine source to the air cylinder to connect this solenoid valve to the electric switch by wiring. The cable 6 may be a rod. The advance/retreat actuator 7 is actuated by operating the electric switch from the inside of the cabin, and is returned so as to make gas flow again by the reset mechanism after excessive flow preventive actuation.</p> |
