In view of this, the utility model provides a kind of urea for vehicle pure water loading system, realizes urea for vehicle production process The automatic filling of middle pure water.

To solve above technical problem, the technical solution of the utility model is：A kind of urea for vehicle pure water loading system, bag Include the main line being connected with the agitator tank in urea for vehicle production system and be connected with main line respectively by branched pipe two Individual incubator；Liquid level sensor and temperature sensor are provided with described two incubators；It is provided with the main line and is added Note pump；Magnetic valve is provided with the branched pipe；The magnetic valve and dispenser pump are connected with controller.By two incubators It is used alternatingly, it is to avoid occur during pure water is automatically injected out of stock, improves production efficiency.

Improved as one kind, high, normal, basic three liquid level sensors are provided with described each incubator.By three liquid Level sensor feeds back water level information to controller so that controller can coordinate two incubators carries out water filling or moisturizing behaviour Make.

As one kind improve, also including a product water tank, the product water tank by triplate line respectively with two incubators Connection.Producing water tank is used to be incubator automatic water supplement.

As a kind of preferred, the magnetic valve being connected with controller is provided between described two incubators and product water tank. For controlling incubator respectively and producing the opening and closing between water tank.

Improved as one kind, the small pump being connected with controller is provided between the product water tank and incubator.

As a kind of preferred, high, normal, basic three liquid level sensors are provided with the product water tank.Produced in water tank for perceiving Liquid level.

Improved as one kind, the flowmeter being connected with controller is provided with the main line.For recording water injection rate, control Opening and closing on main line processed.

Improved as one kind, the flowmeter includes the rotating shaft perpendicular to water (flow) direction；The rotating shaft lower end is fixed with Impeller, rotating shaft upper end is fixed with magnet；Also include coordinating the coil for carrying out magnetic force line cutting with magnet.Current flow driving impeller Rotation, impeller drives the magnet rotation being coaxial therewith.Magnet causes magnetic force line cutting during rotating, form flux change. The change is recorded by controller, the rotating speed for determining impeller, and calculates outflow by fluid publicity.

It is of the present utility model to be beneficial in that：Urea for vehicle pure water loading system with said structure, by automatic Water filling substitutes traditional artificial operation, its efficiency high, and without artificial on duty, and stability is high, is conducive to being lifted the matter of product Amount and yield.Worked by turns using two incubators, it is to avoid out of stock, there is being smoothed out using whole process flow.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is flowmeter schematic diagram.

Marked in figure：1 produce water tank, 2 incubator I, 3 incubator II, 4 agitator tanks, 5 dispenser pumps, 6 small pumps, 7 flowmeters, 8-11 magnetic valves, 71 rotating shafts, 72 impellers, 73 magnet, 74 coils.

Specific embodiment

In order that those skilled in the art more fully understands the technical solution of the utility model, with reference to specific implementation The utility model is described in further detail for mode.

As shown in Figure 1 and Figure 2, the utility model includes the main line being connected with the agitator tank 4 in urea for vehicle production system And the incubator I2 and incubator II3 being connected with main line respectively by branched pipe；In the incubator I2 and incubator II3 It is provided with liquid level sensor and temperature sensor；Dispenser pump 5 is provided with the main line；Electricity is provided with the branched pipe Magnet valve 10 and magnetic valve 11；The magnetic valve 10 and magnetic valve 11 and dispenser pump 5 are connected with controller.In each incubator It is provided with high, normal, basic three liquid level sensors.Including a product water tank 1, the product water tank 1 by triplate line respectively with insulation Case I2 and incubator II3 is connected.It is respectively arranged with what is be connected with controller between incubator I2 and incubator 113 and product water tank 1 Magnetic valve 8 and magnetic valve 9.Produce and be provided with the small pump 6 being connected with controller between water tank 1 and incubator.Produce in water tank 1 and set There are high, normal, basic three liquid level sensors.The flowmeter 7 being connected with controller is provided with main line.The flowmeter 7 includes hanging down Directly in the rotating shaft 71 of water (flow) direction；The lower end of the rotating shaft 71 is fixed with impeller 72, and the upper end of rotating shaft 71 is fixed with magnet 73；Also wrap Include the coil 74 for coordinating with magnet 73 and carrying out magnetic force line cutting.A master control display screen being connected with controller is preferably provided, is used Liquid level, temperature and each magnetic valve opening and closing situation in display incubator I and incubator II.

Workflow of the present utility model is as follows：Magnetic valve 8, magnetic valve 9, magnetic valve 10, magnetic valve 11 are normally closed electricity Magnet valve.Liquid level sensor in incubator I2 and incubator II3 may determine that high, medium and low three kinds of states of water level.And assume just The suitable pure water of temperature is filled under beginning state in incubator I2, incubator II3.

1. the sensor feedback in agitator tank 4 one needs the signal for filling pure water to controller.

2. controller selects any one to have high level and temperature incubator up to standard, such as incubator I2.Open Magnetic valve 10, while it is agitator tank water filling to open water injecting pump 5.Flowmeter 7 is calculated water injection rate, when reaching default, instead Feedback signal is to controller.Controller controls magnetic valve 10 and dispenser pump 5 to close.

3. when sensor feedback low water level signal to the controller in certain incubator, the incubator is no longer noted Water.To controller, controller just locks magnetic valve 11 to close to one low water level signal of sensor feedback of such as incubator II3 State.Being then turned on magnetic valve 9 and small pump 6 carries out moisturizing.After incubator II3 feeds back high water level signal to controller, control Device processed closes magnetic valve 9 and small pump 6, and solves latching solenoid valve 11.

Water filling and the moisturizing action of incubator I2 and incubator II3 alternately, when different carry out moisturizing or water filling work Make.

The above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not be regarded It is that, to limitation of the present utility model, protection domain of the present utility model should be defined by claim limited range.For For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
