[origin: JPH02125200A] PURPOSE: To improve the flushing operatability in a flushing block for a compressed gas container by forming an exhaust gas outlet connected with an extraction borehole, on the flushing block and opening and closing a shut-off valve at the outlet. CONSTITUTION: To replace a compressed gas container including the dangerous contents by using a flushing block 10, a connecting portion 11 is connected with a valve 14 of the container, the valves 14, 19 are closed, an inert gas is flown from a flushing gas inlet 21 to be sent to an outlet 17 of the valve 14 through a borehole 24 and a pipe 23 in an opening state of the shut-off valves 22, 26, and the process gas is mixed with the flushing gas to be exhausted from the outlet 27 through a borehole 25. Then the shut-off valve 22 is closed to stop the supply of the flushing gas, and a new filling container is replaced. In an operating state, the shut-off valves 22, 26 are closed, and the process gas is flown to a process gas outlet 20 through a borehole 16 and a shut-off valve 19 extracted by the valve 14. Whereby the dangerous process gas can be purged from the dead space of the valve or the like.

Die Erfindung betrifft einen Spülblock (10), welcher eine Entnahmebohrung (16) für Prozeßgase und eine Spülgasleitung aufweist, die über einen Spülgasanschluß (21) an eine Spülgasversorgung angeschlossen werden kann. Damit nur eine Armatur (14) in Form einer Ringspülung mit einem Inert- oder Spülgas gespült werden kann, weist der Spülblock (10) einen mit der Entnahmebohrung (16) verbundenen Spülgasausgang (27) auf, der mit einem Absperrventil (26) geöffnet oder geschlossen wird.
