Original state：Under original state, 2 induction tubes in sump are connected with air, the startup assembly pressure being attached thereto
Chamber（Start assembly original state to split）With the pressure chamber for stopping assembly（Stop assembly original state to split）In normal pressure
State.In this case, start assembly part under the action of its sealing column resetting spring, make the sealing surface of sealing column with it is corresponding
Valve seat contacts, and negative pressure gas source interface is activated the cut-off of assembly sealing column with negative pressure valve control interface is connect, and at the same time, stops assembly
Under the action of its sealing column resetting spring, its sealing column is made to be disengaged with sealing surface of seat, and negative pressure gas source interface with connect
Negative pressure valve control interface, which is activated assembly sealing column, to be stopped, the promotion chamber of negative pressure valve（After connecting negative pressure source, negative pressure valve can be opened）It is logical
The medium channel and atmosphere of Liquid level adjusting valve are crossed, negative pressure valve is closed.
Open state：Collecting well fluid level rises, and when reaching height T1, stops induction tube and is closed by liquid level, with liquid level
Rise, the pressure for the pressure chamber being attached thereto increases, and when liquid level reaches T2, the pressure in pressure chamber is enough to overcome reset
The resistance of spring makes the sealing column of stopping assembly being contacted with valve seat, stops assembly sealing pair and closes, and cut-out starts assembly and stops
The air passage of assembly.
Collecting well fluid level rises, and when reaching height Q1, the lower ending opening for starting induction tube is closed by liquid level, with liquid level
Rise, the pressure chamber's pressure being attached thereto increases, and when liquid level reaches Q2, the pressure of the power chamber is enough that resetting spring is overcome to hinder
Power makes the corresponding sealing column of startup assembly be disengaged with sealing surface of seat, starts assembly and opens, negative pressure air source is by being accordingly situated between
Matter channel is opened with chamber, negative pressure valve is promoted, and aspirates liquid in sump, and collecting well fluid level is begun to decline.
It closes, restPoses：When collecting well fluid level is less than Q1, starts induction tube and connected with air, is attached thereto
The pressure chamber's pressure for starting assembly declines, and under the action of its resetting spring, so that corresponding sealing column is contacted with gasket, negative pressure
Source interface is ended with negative pressure valve control interface by sealing column, that is, cuts off negative pressure source.At this point, being closed because stopping assembly, start assembly
Dissengaged positions is in the air passage for stopping assembly, negative pressure valve continues to aspirate in sump still in open state, i.e. negative pressure valve
