Further, the electric control drain valve is a direct-acting electromagnetic valve.
The utility model also provides a take automatic water discharging device's oil water separator's application method, including following step:
the first step is as follows: after a driver starts an engine, the oil-water separator body continuously separates water from diesel oil, when the water level sensor detects that the water in the water accumulation cup reaches the highest water level, the controller receives a signal of the water level sensor and transmits the signal to the instrument, and the instrument starts to give an alarm;
the second step is that: after the engine is turned off, a driver presses down the drainage switch to drain water, the controller performs self-checking before controlling the electric control drainage valve to drain water, if the system is short-circuited or broken, an indicator lamp on the drainage switch flickers, and if the self-checking is normal, the third step is performed;
the third step: the controller controls the electric control drain valve to be opened, and when the water level sensor detects that the moisture of the water accumulation cup reaches the lowest water level, the controller controls the electric control drain valve to be closed.
The utility model discloses following beneficial effect has:
the utility model discloses on original oil-water separator's basis, increase the automatically controlled drain valve that has the controller, realize automatic drainage function, this utility model easy operation, convenient to use, reliability height.
Description of the drawings:

Fig. 2 is a schematic block diagram of the circuit control of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a take automatic water discharging device's oil water separator, including oil water separator body 1, ponding cup 2, level sensor 3 and automatically controlled drain valve 5, ponding cup 2 sets up in oil water separator body 1's bottom, and level sensor 3 and automatically controlled drain valve 5 are all installed on ponding cup 2.
The oil-water separator body 1 is a common oil-water separator and does not need to be specially customized; the water accumulation cup 2 is placed at the bottom of the oil-water separator body 1, the manual water drain valve on the water accumulation cup 2 needs to be detached, and the electric control water drain valve 5 is installed. The thread of the water outlet of the water accumulation cup 2 must be matched with the thread of the electric control drain valve 5.
The water level sensor 3 sets the highest and lowest water levels according to the oil-water separator. The controller is signaled when the water level is highest, and the controller is transmitted to the instrument to prompt a driver to drain water; when the water level is lowest, the signal is sent to the controller to control the drainage signal of the instrument to be closed, and the drainage switch signal is disconnected even if the drainage switch is pressed down.
The drainage switch is a resettable switch with an indicator light. When the electric control drain valve 5 is used, an indicator light of the switch is lightened. When the controller detects the electric control drain valve fault, the controller controls the drain switch indicator lamp to flicker.
The controller receives signals from the engine, the water level sensor and the drainage switch, outputs the signals to the instrument and the electric control drainage valve, and the power supply is provided by the 24V voltage of the whole vehicle.
The electric control drain valve 5 is a direct-acting electromagnetic valve, when the electric control drain valve is electrified, the electromagnetic force generated by the electromagnetic coil lifts the closing member from the valve seat, and the valve is opened; when the power is cut off, the electromagnetic force disappears, the spring presses the closing part on the valve seat, and the valve is closed.

The water level sensor 3 is a sensor arranged in the oil-water separator, and the controller receives and processes signals from the water level sensor in the oil-water separator, so as to further judge whether to send out a high water level alarm signal. The water level sensor is simultaneously provided with a low water level signal, and only when the water level sensor is higher than the lowest water level, the controller can receive signals by pressing the drainage switch.
Because the system is unable to drain water when the engine is operating, the controller receives a signal that the engine is operating. In the working process of the engine, even if a driver presses the drainage switch, the controller can also consider no signal, and the electric control drainage valve can not act.
The system can be provided with an electric control drain valve fault detection function, namely: when the engine stops operating and the water level is between the highest water level and the lowest water level, the drainage switch is pressed down, the controller can detect the fault of the on-off of the coil in the electric control drainage valve, and if the coil fails, the indicator lamp on the drainage switch can flash.
The priority of the controller controlling the electric control drain valve is as follows: and the engine start-stop signal is greater than the highest and lowest water level signal.
