The utility model content

The utility model provides a kind of a plurality of solution tank all to measure the moisturizing fluid level control device of discharge opeing, can overcome the above problems.

the utility model provides a kind of a plurality of solution tank all to measure the moisturizing fluid level control device of discharge opeing, described moisturizing fluid level control device comprises a plurality of Inserting Tubes, the first communicating pipe, detector tube, level switch, the second communicating pipe and water receiver, each Inserting Tube inserts in corresponding solution tank and the bottom of the bottom of Inserting Tube and solution tank keeps same distance, first end by the first communicating pipe between a plurality of Inserting Tubes connects, the second end of the first communicating pipe inserts in detector tube, described level switch is set on described detector tube, the bottom of described detector tube be connected the bottom of water receiver and connect by described the second communicating pipe.

According to concrete technical scheme of the present utility model, wherein, described moisturizing fluid level control device also comprises a plurality of run-down pipes, and each run-down pipe inserts in corresponding solution tank, and described run-down pipe is arranged between the top of the bottom of described Inserting Tube and solution tank.

According to concrete technical scheme of the present utility model, wherein, the run-down pipe of a plurality of solution tanks is arranged on sustained height.

The principle of work that a plurality of solution tank of the present utility model is all measured the moisturizing fluid level control device of discharge opeing is: injected water in water receiver, water in water receiver enters detector tube by the second communicating pipe, when the liquid level in detector tube reaches the level switch operating point, stop injected water in water receiver, because the atmospheric pressure in the atmospheric pressure in water receiver and detector tube equates, so at this moment the liquid level in water receiver is consistent with the liquid level in detector tube; When the liquid level in detector tube reaches the level switch operating point, level switch provides actuating signal, carry out the equivalent fluid injection by liquid injection pipe, when equivalent in each solution tank is injected solution, gas in Inserting Tube is by solution compresses, liquid level in detector tube is reduced, and liquid switch disconnects (being failure to actuate); When having solution to flow out in run-down pipe, stop the equivalent fluid injection; Drawing liquid pump is extracted water in solution tank out, liquid level in the solution tank of liquid level reduction of speed maximum in several solution tanks is dropped to below the bottom of Inserting Tube, can cause gas to enter Inserting Tube, thereby make the liquid level in detector tube increase, when the liquid level in detector tube rises to the level switch operating point, level switch provides actuating signal, carries out the equivalent fluid injection by liquid injection pipe.

The advantage that a plurality of solution tank of the present utility model is all measured the moisturizing fluid level control device of discharge opeing is: only need to use a level switch, just can control a plurality of solution tanks and all measure the moisturizing liquid level control of discharge opeing, save cost and simplify and control, mainly solving a plurality of solution tanks, all to measure the liquid level that in the discharge opeing process, random micro-lack of uniformity error causes unequal, when any one solution tank occurring and first low level occurring, all produce alerting signal; The placement location of solution tank, water receiver, detector tube, level switch can be random; Level switch is arranged on the outer wall of detector tube, and the water in the contact detection pipe, do not need to clean, and level switch can be by solution corrosion.

Description of drawings

The following drawings only is intended to the utility model is done and schematically illustrates and explain, does not limit scope of the present utility model.
