Zusammenfassung:	The utility model relates to a leakage prevention alarm device for gas valves, belonging to a gas alarm device. The utility model is composed of a casing, a power supply, an alarm control circuit, and sensors. The sensors are composed of a temperature sensor and a displacement sensor. The temperature sensor is fixed on the flame zone of a range and is a bimetallic strip structure. The temperature sensor normally opens. The displacement sensor is fixed on a switch screw handle of a gas valve and is a mercury switch or reed switch structure. The utility model can prompt the user to close the gas valve in time, having the advanced prevention effect on gas leakage. The utility model can be used on gas ranges in families, restaurants, dining rooms, etc., having the advantages low cost, long service life, and high safety.
