Title:
GAS SHUT-OFF DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/152040
Kind Code:
A1
Abstract:
The disclosed gas shut-off device (30A-30C) is configured such that control of a control means (33) uses vibration detection by a vibration-sensing means (50) and decrease in flow pressure measured by a pressure measurement means (32) to a value less than or equal to a prescribed pressure value as the criteria of whether to disable restoring a shut-off means (39) from a shut-off state to a supply state. Further, if a fall in one of either the aforementioned vibration or the aforementioned flow pressure is detected and if a fall in the other is further detected within a prescribed time thereafter, the control means (33) switches the shut-off means (39) to the shut-off state, and disables a restore means (38) from restoring the shut-off means (39) to the supply state.
