Abstract

PURPOSE: To miniaturize this device, by checking the working functions of the whole fluid-fuel safety device or by bringing the device under operation to an OFF- like condition by means of a manual operation means, etc. by using an approach switch means for sensing for detecting the movement of a vibration sensing body.
CONSTITUTION: A fluid-fuel safety device is provided with a timer 4 for setting a zone of the time of disuse, an earthquake vibration sensor 5, a switch 6 of an approach switch means for sensing mounted to the sensor 5, etc. in a control box 1. The switch 6 is formed in such a manner that an earthquake sensing control portion S1 consisting of a high-frequency oscillating circuit 62 and a switch circuit 63 is connected to a detecting coil 61 installed to a cover body 53 of the sensor 5 and the vibration of a vibration sensing body 52 is sensed. The switch 6 is connected to a reset switch using a reed switch 94b and a valve control circuit for connecting a constantly-enclosed magnet valve (Diagraming is omitted), thus realizing the desired target.
