Abstract

PURPOSE: To simplify maintenance operations in such a way that in a discharging device for liquefied gas tank in a tank lorry or the like, the bottom lid in an enclosed chamber in which a drain pump is built is enclosed by moving down a regulating member, and liquefied gas in the chamber is substituted by inert gas.
CONSTITUTION: A housing 22 is moved down under fluid pressure in the tank by operating a regulating member 48 installed on a lid plate 24. Hereby, the housing 22 stops at the time when it has come into cntact with the tip of a flanged bush 16. Then, if a valve 60 is closed, the inside of the housing 22 is out off the inside of the tank 10 and comes into its enclosed condition. Next to it, with opening a drain port 56 of the lid plate 24, inert gas is induced through a inert gas supplying port 54 into the housing 22. In result, liquefied gas is drained through the drain port 56, after completion of substitution, a fastener 28 is removed, and the lid plate 24 and the pump 30 are taken out, by which maintenance operations can be done simply and safely.
