1Object-affected harmful factors
If the reaction chamber is flushed with gas to remove oxygen, then oxygen content is reduced, but residual oxygen remains in the reaction chamber
Solution Approach 1:
The patent employs an oxygen sensor to continuously monitor the oxygen content in the reaction chamber and feeds this information back to a control device. The control device adjusts the flushing process based on the detected oxygen levels, enabling precise control to achieve the desired low oxygen environment while avoiding unnecessary prolonged flushing that would reduce productivity.
Solution Approach 2:
The patent changes the parameters of the flushing process by using the oxygen sensor to detect specific oxygen concentration thresholds. Based on these parameter changes, the control device dynamically adjusts flushing duration, gas flow rate, and valve operations to optimize both oxygen removal efficiency and process productivity.
2Device complexity
If manual flushing is performed, then the process is simple, but the oxygen content cannot be precisely controlled
Solution Approach 1:
The oxygen sensor provides real-time feedback on oxygen concentration, allowing the control device to precisely adjust flushing operations. This feedback mechanism enables accurate oxygen content control while keeping the overall system structure relatively simple through automated control logic.
Solution Approach 2:
The patent replaces manual mechanical flushing operations with an automated control system that uses electronic sensors and programmable logic. This substitution improves measurement precision and oxygen content control while the modular design keeps the added complexity manageable.

AI summary
The invention relates to a pressure vessel, having: a reaction chamber (2) as a pressure space for the initiation and/or facilitation of chemical and/or physical pressure reactions of samples (P) accommodated in the reaction chamber (2); a fluid inlet (20) with a feed valve (21) which is adjustable between an open position, for the feed of a fluid, preferably a flushing gas, into the reaction chamber (2), and a closed position, for stopping the feed of the fluid; a fluid outlet (30) with a discharge valve (31), which is adjustable between an open position, for the discharge of a fluid out of the reaction chamber (2), and a closed position, for stopping the discharge of the fluid out of the reaction chamber (2); and an oxygen sensor (33) for detecting an oxygen content in the reaction chamber (2). The pressure vessel (1) furthermore has a control device which is configured to control the feed valve (21) and the discharge valve (31) on the basis of the oxygen content detected by the oxygen sensor (33), such that the reaction chamber (2) is flushed via the feed and discharge valves (21, 31) situated in the open position, and at least the discharge valve (31) switches from the open position into the closed position as soon as a predetermined oxygen content is undershot. The invention also relates to a corresponding method.
