Specific embodiment

Explanation that the present invention will be further explained with reference to the accompanying drawings and examples.

As Figure 1-Figure 2, a kind of automatic control water plug, the device include upper tank body 1 and lower tank 2, the upper tank body 1 It is connected with lower tank 2 by a normally open solenoid valve 3, vacuum pumping hole 4 is offered at the top of the upper tank body 1, the vacuum is taken out 4 one end of stomata is connected with vacuum pump 5, and 1 side of upper tank body is equipped with gas-liquid inhalation interface 6, and 2 outer upper of lower tank is set There is normally closed solenoid valve 7, lower tank 2 can be made to communicate with the outside world when opening normally closed solenoid valve 7,2 bottom of lower tank is connected with one Suction pump 8, described 8 one end of suction pump are connected with check valve 9, further include for controlling normally open solenoid valve 3,7 and of normally closed solenoid valve The control device that suction pump 8 works, the control device include set on the intracorporal electronic liquid level gauge 10 of 2 chamber of lower tank and being set to normal The PLC controller 11 of 7 lower section of solenoid valve is closed, described 11 one end of PLC controller is electrical connected with electronic liquid level gauge 10, the other end It is electrically connected respectively with normally open solenoid valve 3, normally closed solenoid valve 7 and suction pump 8.

The upper tank body 1 and lower tank 2 are that stainless steel material is made.The suction pump 8 is DC diaphragm formula water pump.

Specific implementation process of the invention are as follows: when the automatic control water plug is run, rectifying water system is connect by gas-liquid sucking Mouth 6 is connected with automatic control water plug and forms airtight cavity, and under the suction of vacuum pump 5, the gas-liquid in rectifying water system is mixed It closes object and enters upper tank body 1 from gas-liquid inhalation interface 6, wherein gas is sucked out by vacuum pump 5 from vacuum pumping hole 4, and liquid then passes through Normally open solenoid valve 3 flows into lower tank 2, and liquid gradually accumulates in lower tank 2, when the Liquid level of electronic liquid level gauge 10 is arrived in accumulation When the upper limit, electronic liquid level gauge 10 provides control signal to PLC controller 11, controls normally open solenoid valve 3 by PLC controller 11 and closes It closes, while normally closed solenoid valve 7 is opened, outside air can enter in lower tank 2 from open normally closed solenoid valve 7, and suction pump 8 is dynamic Make, the liquid in lower tank 2 is extracted out, when the liquid level in lower tank 2 drops to Liquid level lower limit, suction pump 8 stops work Make, and normally closed solenoid valve 7 is closed, normally open solenoid valve 3 reopens, and the liquid in upper tank body 1 is infused again under the effect of gravity at this time Enter in lower tank 2, loop back and forth like this, can constantly the gas-liquid mixture entered in upper tank body 1 be separated and is discharged.

Above content is example and explanation of the invention, but does not mean that the obtainable advantage of the present invention is so limited, all It is wherein one the advantages of may being realized in simple transformation, and/or some embodiments to structure in practice process of the present invention It is a or it is multiple within the scope of protection of this application.
