SAFETY MANAGING SYSTEM FOR GAS APPARATUS

Japanese Patent JP3657639

B2

PURPOSE: To monitor gas apparatuses of all types which are left in an ON-state and to properly and automatically disconnect the feed of gas by providing a sounding means to output a monitoring sound at a frequency matched with an individual gas apparatus at loudness responding to a gas flow rate.
CONSTITUTION: Sounding means 7-9 arranged in the respective gas flow passages of gas apparatuses 4-6 under operation output respective monitoring sounds of a given frequency at loudness responding to a gas flow rate to monitor the working state thereof. In which case, when the working sate of each of the gas apparatuses 4-6 is deviated from an ordinary state, the feed of gas is automatically disconnected by outputting an operation signal to cutoff valves 10-12 installed at a gas meter 2 by a cutoff valve control means 14. Further, when the cutoff means 14 is located in the flow passage of each of the gas apparatuses 4-6, in a case the working state of each of the gas apparatuses 4-6 is deviated from an ordinary state, the cutoff valve means 14 outputs an operation signal to the cutoff valves 10-12 located in the flow passages of the corresponding gas apparatuses 4-6.
