VALVE SETTING DEVICE FOR A GAS PRESSURE REGULATOR, CAPABLE OF PRECISELY SETTING THE REFERENCE PRESSURE OF A SAFETY VALVE IN A CONSTRUCTION SITE

摘要

PURPOSE: A valve setting device for a gas pressure regulator is provided to precisely and easily set the reference pressure of a safety valve and improve the precision of the setting.;CONSTITUTION: A valve setting device for a gas pressure regulator comprises a pressure display part (300) and a pressure control part (200). The pressure display part includes a pressure sensor (310). The pressure control part includes a compressor (210) and a regulator (220). The compressor compresses fluid. The regulator is connected to the compressor and supplies the compressed fluid to a valve of a gas pressure regulator. The pressure sensor of the pressure display part is connected to the regulator and measures the pressure of the fluid supplied to the valve.;COPYRIGHT KIPO 2013;[Reference numerals] (100) Power part; (110) Main switch; (120) Compressor switch; (200) Pressure control part; (210) Compressor; (220) Precision regulator; (230) Jog dial; (300) Pressure display part; (310) Pressure sensor; (320) Display sensor; (A) Constant pressure device SSV/PSV
