REMOTE INTERRUPTION SYSTEM OF VALVE AND METHOD THEREOF

摘要

PURPOSE: A remote interruption system of a valve is provided to be able to interrupt a valve by using the expansive force of the compressed air which is stored in a valve box. CONSTITUTION: The interruption system of a valve which prevents the feed of gas by interrupting a valve placed at a long distance in case of emergency by measuring pressure of a gas pipe is formed by:a valve controller(50) installed on each valve box to output the relevant signal to a circumstantial studio(10) by measuring the state of a valve and to output the valve control signal by the control of the circumstantial studio; a main transmitter/receiver(30) outputting the control signal through a metal pipe by converting the control signal outputted from the valve controller; and a valve driving unit(100) closing the gas pipe by the valve control signal outputted from the valve controller.
