Fill-in-the-blank: During the operation of the vaporization furnace, it is not allowed to (open) the inlet and outlet valves of the lock hopper simultaneously to prevent safety accidents; therefore, during design, (electrical interlock or pneumatic interlock) is installed between the inlet valve and the outlet valve of the lock hopper, thereby preventing both valves from being (opened) at the same time in terms of circuitry. The results have been announced; please stop posting further replies.
Open simultaneously； interlocking ； Open.
Turn off the safety valve and cut off power at the same time
During the operation of the gasification furnace, it is not allowed to open the inlet and outlet valves of the lock hopper to prevent safety accidents; therefore, a logical interlock is installed during design between the lock hopper inlet valve and the outlet valve, thereby preventing both valves from being opened simultaneously in terms of circuitry.
During the operation of the gasification furnace, it is not allowed to close the inlet and outlet valves of the lock hopper in order to prevent safety accidents; therefore, interlocks are installed between the lock hopper inlet valve and the outlet valve during design, thereby preventing both valves from being closed simultaneously at the electrical level.
Open simultaneously/air circuit interlock/Open
During the operation of the gasification furnace, it is not allowed to open the inlet and outlet valves of the lock hopper simultaneously to prevent safety accidents; therefore, interlocking is implemented in the design between the lock hopper inlet valve and the outlet valve, thereby preventing both valves from being energized at the same time. It is also suggested that the original poster could release some of the short-answer questions at the end for everyone to study together*
Open simultaneously, action permission condition, enable signal
