Technical field

The present invention relates to a kind of water level control system.

Background technology

In daily life or producing, people run into through regular meeting needs to keep the constant situation of water level, just needs sometimes to keep water level constant as the operation of facilities such as water tank, pond, filter tank.Existing method mainly be adopt machinery or electromagnetism the method by-pass valve control unlatching or close and then control water level, it all is the water level controller of mechanical type or electronic type that the device that adopts mainly contains ball-cock assembly, electronic type water level switch, level relay etc., but the complex structure of these devices, serviceable life are short, cost is higher, adaptive faculty is stronger, wherein portioned product is relatively stricter to producing the requirement of safeguarding, be easy to generate phenomenon such as leak, safe reliability is relatively poor.Will inevitably there be certain error in existing method owing to adopt the device of machinery or electromagnetism, and therefore the precision of the constant water level of being controlled is lower.

Summary of the invention

The present invention controls the lower problem of precision of constant water level in order to solve the existing device of machinery or electromagnetism that adopts, thereby provides a kind of high precision constant water level auto control system.

The constant water level auto control system of a kind of high precision, it comprises water tank and water tank bracing frame, a water tank is suspended on the top of the container for the treatment of water filling, and the water delivering orifice of a water tank is towards the container for the treatment of water filling, and the water delivering orifice of a described water tank stretches in the container for the treatment of water filling; The center line of the water delivering orifice of a water tank and the angle of vertical direction are between 0 degree and 90 degree, and No. one water tank is fixed on the water tank bracing frame.

Beneficial effect: the present invention is when work, water in water tank flow in the container for the treatment of water filling by water delivering orifice, the water delivering orifice of the water tank of water flooding in the container for the treatment of water filling, because a water tank location is constant, therefore treat that the water level in the container of water filling also must keep constant, and, therefore do not have the error that produces by this this device because the present invention does not adopt any machinery or calutron, therefore the present invention is than conventional device, and the constant precision of its water level is very high.

Description of drawings

Fig. 1 is a structural representation of the present invention; Fig. 2 is the structural representation of the specific embodiment of the invention four.

Embodiment

Embodiment one, this embodiment is described in conjunction with Fig. 1, the constant water level auto control system of a kind of high precision, it comprises water tank 2 and water tank bracing frame 1, a water tank 2 is suspended on the top of the container 5 for the treatment of water filling, and the water delivering orifice of a water tank 2 is towards the container 5 for the treatment of water filling, and the water delivering orifice of a described water tank 2 stretches in the container 5 for the treatment of water filling; The center line of the water delivering orifice of a water tank 2 and the angle of vertical direction are between 0 degree and 90 degree, and No. one water tank 2 is fixed on the water tank bracing frame 1.

Principle of work: a water tank 2 of the present invention is upside down in the top of the container 5 for the treatment of water filling, water in water tank 2 flows into the pond through water delivering orifice under the effect of gravity, the inside of a water tank 2 forms negative pressure simultaneously, air enters the inside of a water tank 2 through water delivering orifice under the effect of the outside of a water tank 2 and air pressure inside difference.The container 5 interior water levels for the treatment of water filling progressively rise, until the water delivering orifice that floods a water tank 2, air can not enter water tank 2 inside again No. one, cause in a water tank 2 and form negative pressure, No. one water tank 2 interior water can not flow in the container 5 for the treatment of water filling owing to the negative pressure swabbing action again, thereby water level is controlled in the aperture position of a water tank 2, has promptly realized the control of constant water level.

The present invention only relies on the effect of liquid gravity and atmospheric pressure to realize without any need for additionaling power; The present invention is simple in structure, working stability.

The present invention is under the situation of corrosion resistivity and structural stability at the material that guarantees a water tank 2, can also carry multiple liquid, realizes the constant of multiple liquid level.

The difference of embodiment two, this embodiment and the constant water level auto control system of embodiment one described a kind of high precision is, has water supplement port on the water tank 2.

The difference of embodiment three, this embodiment and embodiment one or the constant water level auto control system of two described a kind of high precision is, it also comprises plug 3, No. one water tank 2 tops have water supplement port, and plug 3 is with the sealing of the water supplement port on water tank 2.

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.
