Abstract

PURPOSE: A method of blocking a safety gas valve in case of fire is provided to prevent the danger of fire by blocking a safety gas valve if the danger of gas explosion is detected in case of what a temperature around a gas pipe in a house wherein a fire breaks out is higher than a preset temperature. CONSTITUTION: A method of blocking a safety gas valve in case of fire comprises the following steps. A household number is successively selected(S301). A household is selected corresponding to the selected household number(S302). A present temperature(T) of the selected household compares with a set temperature(T1) and decides(S303). A household number sequential selection is repeated if the present temperature of the selected household is lower than the set temperature(S304). A warning bell is rung in the selected household if the present temperature of the selected household is higher than the set temperature(S305). The closing of a first valve of the selected household is confirmed(S306). The closing of the first valve of the selected household is practiced if the first valve of the selected household is not shut(S307). A household number which 1 is added to the lowest digit of the selected household number is selected if the first valve of the selected household is shut(S308).

Description

How to shut off gas safety valve in case of fire {GAS SAFETY VALVE LOCKING METHOD, IN CASE OF A FIRE OCCURRENCE}

The present invention relates to a method for shutting off a gas safety valve when a fire occurs. More specifically, when the ambient temperature of the gas pipe of a generation in which a fire occurs is greater than a set temperature, the gas safety valve is shut off and the fire is blocked. Is extended to neighboring households, and if the ambient temperature of the gas pipes of the neighboring households is higher than the set temperature, it is also considered that there is a risk of gas explosion. Is expanded, the gas safety valve installed in the second gas pipe and the third gas pipe connected to the adjacent generation, and the gas safety valve installed in the second gas pipe and the third gas pipe connected to the generation where the fire occurred. It relates to a gas safety valve blocking method in the event of a fire to cut off.

In general, apartment houses such as apartments are provided with a gas supply source installed underground and a gas valve for blocking gas from the gas supply source.

In the facility, the gas supply pipe is provided with a pipe for supplying gas in block units and a pipe for supplying generations, and a gas valve is installed in each pipe.

If a pipe is heated due to a fire, there is a risk of gas explosion.

A technique for detecting a gas valve by detecting smoke or ambient temperature has been known (Korean Patent Publication No. 10-2005-0116965, Japanese Patent Publication No. 2003-0031947), and the Republic of Korea Patent Publication No. -0031947; publication date; April 23, 2003),

8 is a flowchart illustrating a gas leakage alarm blocking method according to the related art.

As shown in Figure 8, the prior art is a technology that shuts off the gas valve installed in the household and alarm sound when it is determined that the temperature detected by the temperature sensor is a fire state.

However, if a fire occurs and not only the generation of fire but also the fire is extended to the neighboring generation, and the neighboring generation is also at risk of gas explosion, the gas safety valve of the neighboring household must be shut off and the gas safety valve of the neighboring household must be shut off. In the event of a fire escalation, the gas safety valves installed in the second gas pipe connected to the adjacent generation, the gas safety valve installed in the third gas pipe, and the second gas pipe and the third gas pipe connected to the generation where the fire occurred. No technology has been developed to shut off the valve.

Therefore, the first object of the present invention is to shut off the first valve of the generation in which the fire occurred in the event of a fire, and the second object of the present invention is to shut off the first valve of the adjacent generation in case the fire occurs and the fire spreads to the adjacent generation. The third object of the present invention is to provide a second gas pipe connected to the adjacent generation, the third gas pipe connected to the adjacent generation, when the fire is to be extended from the generation of generation to the adjacent generation to shut off the first valve of the adjacent generation.
