2, switching tap water need to be manually removed daily, can not also know when switching switch.
Utility model content
The utility model provides a kind of recycle-water and tap water switching system, to solve problem of the prior art.
To solve the above problems, the one aspect as the utility model, provides a kind of recycle-water and tap water switches
System, comprising: water tank, for storing recycle-water, the entrance of the water tank is connect with recycle-water inlet pipe；First solenoid valve,
Entrance is connect with running water pipe, and outlet is connect with production line pipeline；The outlet of second solenoid valve, entrance and the water tank connects
It connects, outlet is connect with the production line pipeline；First liquid level sensor is set in the water tank, in the water storage
The water level of tank generates the first signal when being higher than first liquid level sensor, otherwise generates second signal；Second liquid level sensor,
It is set in the water tank, third letter is generated when being higher than second liquid level sensor for the water level in the water tank
Number, fourth signal is otherwise generated, and the position of second liquid level sensor is lower than first liquid level sensor；Controller,
It is connect with first solenoid valve, second solenoid valve, the first liquid level sensor and the second liquid level sensor, for receiving at the same time
The first solenoid valve closing, second solenoid valve opening are controlled when first signal and the third signal, and same
When control that first solenoid valve is opened, the second solenoid valve is closed when receiving the second signal and the fourth signal.
Preferably, the first output pin of the controller passes through the control terminal of the first relay and first solenoid valve
Second output pin of connection, the controller is connect by the second relay with the control terminal of the second solenoid valve.
By adopting the above-described technical solution, the utility model can be automatically realized the switching of tap water and recycle-water,
Operating efficiency can be improved, prevention is because producing quality risk caused by cutting off the water.

Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The one aspect of the utility model provides a kind of recycle-water and tap water switching system, comprising: water tank 1 is used
In storage recycle-water, the entrance of the water tank 1 is connect with recycle-water inlet pipe 2；First solenoid valve 3, entrance and running water pipe 4 connect
It connects, outlet is connect with production line pipeline 5；Second solenoid valve 6, entrance are connect with the outlet of the water tank 1, outlet and the life
Producing line pipeline 5 connects；First liquid level sensor 7 is set in the water tank 1, for being higher than in the water level of the water tank 1
The first signal is generated when first liquid level sensor 7, otherwise generates second signal；Second liquid level sensor 8 is set to described
In water tank 1, third signal is generated when being higher than second liquid level sensor 8 for the water level in the water tank 1, is otherwise given birth to
At fourth signal, and the position of second liquid level sensor 8 is lower than first liquid level sensor 7；Controller 11, and it is described
First solenoid valve 3, second solenoid valve 6, the first liquid level sensor 7 and the connection of the second liquid level sensor 8, for receiving institute at the same time
The closing of the first solenoid valve 3, the opening of the second solenoid valve 6 are controlled when stating the first signal and the third signal, and same
When control that first solenoid valve 3 is opened, the second solenoid valve 6 is closed when receiving the second signal and the fourth signal
It closes.
When recycle-water is finished, the liquid level in water tank 1 is lowered so that the first liquid level sensor 7 and the second liquid level pass
Sensor 8 is both turned on, i.e., controller obtains the second signal and the second signal simultaneously, then controls first solenoid valve
3 open, the second solenoid valve 6 is closed, and are supplied to production line pipeline 5 using tap water at this time；When the liquid level liter in water tank 1
It is down to the first liquid level sensor or more, so that when the first liquid level sensor 7 and the second liquid level sensor 8 disconnect, i.e. controller
First signal and the third signal are obtained simultaneously, then controls the closing of the first solenoid valve 3, the second solenoid valve
6 open, and are supplied to production line pipeline 5 using recycle-water at this time；If not above-mentioned two situations, then two solenoid valves are kept
State is constant.
By adopting the above-described technical solution, the utility model can be automatically realized the switching of tap water and recycle-water,
Operating efficiency can be improved, prevention is because producing quality risk caused by cutting off the water.
Preferably, the control that the first output pin of the controller 11 passes through the first relay 9 and first solenoid valve 3
End connection processed, the control terminal that the second output pin of the controller 11 passes through the second relay 10 and the second solenoid valve 6
Connection.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
