Title:
FLAME ARRESTOR
Document Type and Number:
Japanese Patent JP3882000
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a frame arrestor capable of detecting and displaying the clogging of a flame extinguishing element in an extremely safe form using increase in differential pressure.
SOLUTION: The flame arrestor 1 to be set in a combustible gas passage comprises an upstream bypass pipe 9 derived from the passage on the upstream side from a flame extinguishing part 5 in the flame arrestor 1, a downstream bypass pipe 10 derived from the passage on the downstream side from the flame extinguishing part 5, and a clogging detecting indicator 11 arranged between the upstream bypass pipe 9 and the downstream bypass pipe 10. The indicator 11 includes a detection part performing mechanical detection when the differential pressure between the gas pressure of the upstream bypass pipe 9 and the gas pressure of the downstream bypass pipe 10 reaches a predetermined value or more; and a display part performing, based on the operation of the detection part, display through a magnetic means.
