PRESSURE REDUCING MECHANISM FOR LIQUEFIED GAS

摘要

PROBLEM TO BE SOLVED: To operate a pressure reducing means normally even if the re- liquefaction of gas occurs in a pipe by providing a recessed part to reserve gas re-liquefied in the pipe at the pre-pressure reduction position of the pressure reducing means in a device where the pressure reducing means is provided in a cylinder to reserve liquefied gas through a pipe. ;SOLUTION: When high-pressure gas enters first screw holes 131a, 131a of a re-vaporizing mechanism 12 from a cylinder through a high-pressure hose 7, it passes first through holes 131b, 131b, and enters a recessed part 133 through a first passage 141. Next it passes a second passage 142, enters a second through hole 132b, and flows through a second screw hole 132a into a single stage regulator 3 where a pressure is reduced to a specified level. When a temperature inside the hose 7 is lowered more from that inside the cylinder, a re-liquefaction of gas occurs in the hose and the liquefied gas tends to enter the single stage regulator 3 through the re-vaporizing mechanism 12. However, because it is reserved in a recessed part 133, only vaporized gas is flowed into the single stage regulator 3.;COPYRIGHT: (C)1997,JPO
