APPARATUS FOR CONTROLLING THE GAS CONCENTRATION OF A PRESSURE CONTAINER CAPABLE OF CONTROLLING THE INTERNAL PRESSURE OF A RECEIVING SPACE IN A PRESSURE CONTAINER HARDENING OVEN

摘要

PURPOSE: An apparatus for controlling the gas concentration of a pressure container is provided to control internal gas concentration in high pressure and high temperature environments.;CONSTITUTION: An apparatus for controlling the gas concentration of a pressure container comprises a gas concentration detecting device(8) and a control unit(10). The gas concentration detecting device detects the internal gas concentration of a receiving space(90) by time. The control unit is connected to the gas concentration detecting device, a first valve(11), and a second valve(12); sets a predetermined concentration; determines whether or not the internal gas concentration of the receiving space is reached to the predetermined concentration according to the results detected in the gas concentration detecting device; and controls the first and second valves according to the determined results.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Control unit; (100) Gas source; (81) Gas concentration detecting device; (82) Gas parameter adjusting device; (821) Flow control valve; (93) Heating module; (94) Turbo fan; (95) Motor; (96) Temperature sensor; (97) Pressure sensor
