Abstract

PURPOSE:To purge the fluid in a dead space of a Bourdon tube completely, by making it possible to open the Bourdon tube in a pressure gage with the operation of an opening and closing valve. CONSTITUTION:When gas or liquid is purged, a cylinder 11 is closed and a stop valve 13c is opened so as to change gas into inactive gas. An opening and closing valve 9 is opened, and the inactive gas is sent into a Bourdon tube 2. Then, the gas or the liquid flows in the direction of an arrow 8a in an inner tube 2b of the Bourdon tube 2 when the pressure of the inactive gas is received. The gas or the liquid is discharged through a flange 10 as shown by an arrow 8b. Since the Bourdon tube 2 can be opened by the operation of the opening and closing valve 9, the fluid in the dead space in the Bourdon tube 2 can be completely purged.
