Pressure-resistant-container gas leakage detecting device for a vehicle to which a discharge tube casing is attached

Abstract

A pressure-resistant-container gas leakage detecting device for a vehicle, to which a discharge tube casing is attached, includes: a casing having a first casing member and a second casing member coupled to the first casing member to form an internal space; a pressure-resistant container having a body coupled to the interior of the casing and a discharge tube exposed to the outside of the casing, the discharge tube adapted to introduce gas thereinto and to discharge gas therefrom; the discharge tube casing adapted to cover the discharge tube; a first gas leakage detecting sensor attached to the discharge tube casing; corrosion-preventing gas injected between the pressure-resistant container and the casing to be filled thereinto higher or lower than atmospheric pressure; and a gas pressure detecting sensor coupled to the casing to detect the occurrence of the change in the pressure of the corrosion-preventing gas.
