AI Technical Summary
The existing steam generator switching device cannot simultaneously close one gas pipe and open another when switching gas pipes, resulting in intermittent shutdowns, affecting the normal use of the equipment, and reducing the ease of switching.
By employing a switching sealing assembly and a transmission assembly, and through the cooperation of a piston rod and a lead screw driven by a motor, the air pipe can be opened and closed simultaneously, avoiding interruptions during machine downtime. The sealing performance is improved by sealing rings and sealing rings, ensuring the stability of the switching process.
This system enables seamless switching of the air tubes, improving the ease of equipment switching. Furthermore, the sealing components ensure the device's airtightness and stability, enhancing its usability.
