GAS MULTIPOINT MIXER AND GAS DETECTING SYSTEM USING IT

摘要

PROBLEM TO BE SOLVED: To provide a gas detecting system enhanced in safety capable of discovering a gas leak and capable of rapidly performing the refuge correspondence thereof. SOLUTION: The gas detecting system is equipped with a means so constituted that gas sampling pipes are individually connected to a gas multipoint mixer from a plurality of gas leak monitoring places and processed into an L shape so as to turn the opening parts of the gas sampling pipes upward to allow gases to impinge against the upper wall in a gas atmosphere container to uniformly mix them and a means for equally sucking the gases into a gas detector of every kind by the gas sampling pipes connected to the container so that the opening parts processed into the L shape are turned downward to accurately sense a leak concentration. Since the gas sampling pipes are installed individually, the material of the gas sampling pipes fitted to gas characteristics can be selected and sampling can be always performed from the gas leak monitoring places.
