[0045] Working principle: in the initial state, the water inlet manual valve 7 and the water outlet manual valve 8 are in the open state, the tank body 1 is empty or the liquid level is lower than the low liquid level limiter 401, the low liquid level sensor detects the low liquid level signal and transmits to the controller, the controller receives the low liquid level signal, controls the water inlet electric valve 2 to open and the drainage pump 5 to close, and the high temperature and pressure gas-containing water medium enters the tank body 1 in turn through the water inlet manual valve 7, the filter 9 and the water inlet electric valve 2. At the same time, since the initial pressure in the tank body 1 is low, the high liquid level limiter 402 (sensing float ball) is in the low position, the exhaust pipe 302 is in the open state, the micro-bubbles in the water medium are released under normal pressure, and as the water inlet continues, the liquid level in the tank body 1 rises, the low liquid level limiter 401 (sensing float ball) floats to above the third limit 406; when the liquid level reaches the high liquid level threshold, the high liquid level limiter 402 (sensing float ball) floats to below the first limit 404, the sliding block in the exhaust pipe 302 is driven to move up by the exhaust linkage rod 301, the exhaust pipe 302 is closed, the exhaust is stopped, the high liquid level sensor triggers the high liquid level signal, the controller receives it and controls the water inlet electric valve 2 to close and the drainage pump 5 to start. The degassed water medium is discharged to the external pipeline through the hose 6, the drainage pump 5, the check valve 10 and the water outlet manual valve 8. During the liquid level lowering process, the high liquid level limiter 402 sinks, and the exhaust pipe 302 reopens; when the liquid level drops to the fourth limit 407, the low liquid level sensor triggers the water inlet again, and the above-mentioned cycle is repeated. When the pressure sensor 13 detects that the pressure in the tank body 1 is too large and the exhaust sensor detects that the exhaust pipe 302 is in the closed state, the alarm is triggered, and the water inlet manual valve 7 and the water outlet manual valve 8 are manually closed for maintenance of the device.
