Abstract
The present invention provides a gas leakage detecting apparatus capable of detecting a gas leak in a cylinder cabinet with accuracy. The gas leakage detecting apparatus comprises a first air take-out pipe for taking out air from the inside of an exhaust duct of a cylinder cabinet and leading the same air to a gas sensor; a second air take-out pipe for taking out air at a given position in said cylinder cabinet and leading the same air to said gas sensor; a first shut-off valve and a second shut-off valve respectively provided on the respective air take-out pipes so that air from these air take-out pipes is selectively led to said gas sensor; and a control means for controlling the opening and closing operation of these shut-off valves. Owing to this construction, one is able to monitor the location of the gas leak upon taking out air from the cylinder cabinet through the second air take-out pipe.
