The course of work of present embodiment is: original state, No. one valve 4 is closed, water supplement port 2 sealings.
During work, open water supplement port 2,, then, use plug (rubber plug) sealing water supplement port 2 topped up with water in water tank 2.The water of opening in 4, numbers water tanks 2 of a valve treats in the container 5 of water filling that by the water delivering orifice inflow simultaneously, ambient atmos enters water tank 2 inside No. one by water delivering orifice, realizes water and gas exchange, with water tank of balance 2 inside and outside pressure.Treat that the water level in the container 5 of water filling constantly rises, until the water delivering orifice that floods a water tank 2.At this moment, gas can not enter in water tank 2 again, and the water in water tank 2 also can't flow out from a water tank 2 again, and container 5 middle water levels for the treatment of water filling are by the constant water delivering orifice position that is controlled at a water tank 2.
When the outside draining of the container 5 for the treatment of water filling, when container 5 decline of water tables for the treatment of water filling, the water delivering orifice of a water tank 2 communicates with air, air enters in water tank 2, cause the water in the water tank 2 to flow out to the container 5 for the treatment of water filling once more, the water level in the container 5 for the treatment of water filling floods the water delivering orifice of a water tank 2 once more.Carry out so repeatedly, realize to keep treating that the water level in the container 5 of water filling is constant.
When the current in water tank 2 to the greatest extent after, close valve 4 No. one, original state is got back to by system.
Embodiment four, this embodiment is described in conjunction with Fig. 2, this embodiment is with the difference of the constant water level auto control system of embodiment three described a kind of high precision, it also comprises water tank 7 No. two, described water tank 2 lower sidewall have water supplement port, the side wall upper part of a described water tank 2 has scavenge port, the moisturizing hole of a described water tank 2 is communicated with the water delivering orifice of No. two water tanks 7, and the air-vent of a described water tank 2 is communicated with the scavenge port of No. two water tanks 7.
The difference of embodiment five, this embodiment and embodiment one or the constant water level auto control system of four described a kind of high precision is, it also comprises valve 4 No. one, a described valve 4 is arranged on the water delivering orifice place of a water tank 2, is used to control passing through or ending of water in water tank 2.
The difference of embodiment six, this embodiment and the constant water level auto control system of embodiment five described a kind of high precision is, also comprise two No. two valves 9, described two No. two valves 9 are separately positioned on the water delivering orifice place and the scavenge port place of No. two water tanks 7.
