GAS COLLECTOR FOR HOT HYDROSTATIC PRESSURE PRESSURIZER

摘要

PURPOSE: To accomplish automatic connection switching of a gas cylinder to a pressure container by applying a valve opening output to shutoff valves for outlets in the rising order of pressure from a cylinder group lower in pressure during the pressure operation of a gas and the valve opening output to the shutoff valves for outlets in the falling order of pressure from the cylinder group higher in pressure during the differential pressure recovery operation. ;CONSTITUTION: Gas pressure signals are introduced from a pressure container detection means 4 for detecting a gas pressure of a pressure container and a cylinder pressure detection means 5 for detecting a gas pressure of a gas collector to apply a valve opening output to shutoff valves 8A-8D for outlets in the rising order of pressure from a gas cylinder group 1 lower in pressure during the pressure operation of a gas and the valve opening output to the shutoff valves 8D-8A for outlets in the falling order of pressure from the gas cylinder group 1 higher in pressure during the differential pressure recovery operation by an opening/closing control means 7 according to the balance of a difference between both the pressure signals. This accomplishes automatic connection switching of a gas cylinder to a pressure container.;COPYRIGHT: (C)1996,JPO
