Abstract
PURPOSE: To make easy to replace shut off valves, by means of providing special shut off valves respectively on the two gas supply pipes which connect a crude gas ascending pipe with a small bell hopper and on two gas exhaust pipes which connect a small bell hopper to atmosphere.
CONSTITUTION: On two gas supply pipes 30a, 30b between a crude gas ascending pipe 7 and a small bell hopper 3, two shut off valves 31a, 32a and 31b, 32b, having their seal-replacing ports 28a, 28b face to face with each other, are installed, and shut off valves 34a, 34b are also installed on two exhaust gas pipes 33a, 33b. In each shut off valve, valve bodies 26a, 26b are provided by the intermediary of arms 23a, 23b rotated by shafts 24a, 24b which intersect a casing 20 at right angles, and are made to be taken out from the casing 20 for replacement by dismantling covering members 29a, 29b. For example, when the valve body 26a of the shut off valve 31a, 32a on the gas supply pipe 30a becomes worn out, the valve body 26b is made to close the supply pipe 30a, while the operation is continued by the shut off valve 31b, 32b on the supply pipe 30b, so that the valve body 26a can be taken out from the casing 20 for replacement.
