COMBINED DEVICE COMPRISING A PRESSURE MANOMETER AND PRESSURE REGULATOR, AND SAFETY MANOMETER

摘要

P THE COMBINED DEVICE CONSISTING OF A PRESSURE GAUGE 12, 44, 46 AND A SAFETY PRESSURE DETENDER 12, 48, 50 TO BE CONNECTED TO SYSTEMS IN WHICH A FLUID PRESSURE CAN CAUSE EXPLOSIONS WHICH MAY INJURY PERSONNEL AND DAMAGE ENVIRONMENTAL EQUIPMENT, INCLUDES MEANS 44, 46 FOR A MORE ACCURATE MEASUREMENT OF THE FLUID PRESSURE REGENERATING IN THE SYSTEM TO WHICH THE DEVICE IS CONNECTED, AS LONG AS PRESSURE OF THE SYSTEM REMAINS INCLUDED IN THE WORKING RANGE OF THE MANOMETER. HOWEVER, IF THE PRESSURE OF THE SYSTEM EXCEEDS THE NORMAL PRESSURE CORRESPONDING TO THE MAXIMUM READING ON THE SCALE OF THE MANOMETER, THE DEVICE INSTANTLY AND AUTOMATICALLY ENSURES THE INSTALLATION OF THE SYSTEM AT THE ATMOSPHERE. AFTER TURNING TO THE ATMOSPHERE, THE PRESSURE RELIEF MECHANISM 46, 50 MUST BE TURNED UP MANUALLY. / P P APPLICATION TO THE EQUIPMENT OF PRESSURIZED FLUID CIRCUITS. / P
