Embodiment Construction
[0029]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] As the first embodiment of the present invention, such as Figure 2 to Figure 4 As shown, taking three water tanks as an example, and other analogies, a multi-water tank water level control device includes a main water inlet pipe 1, a main water inlet valve YA1, a Unicom water pipe 60, a low limit SQ1, a high limit SQ2, and several water tanks . PLC control system, characterized in that: a Unicom water hole (41, 41', 41 ") connected to Unicom water pipe (60) ...

Disclosed in the invention is a multi-water-tank water level control device comprising a main water inlet pipe, a main inlet valve, a low limit, a high limit, connector units, a plurality of water tanks, and a PLC control system. The device is characterized in that the multiple water tanks are successively connected together by the connector units; the main inlet valve is arranged at the main water inlet pipe to control on / off of the main water inlet pipe; and the PLC control system controls the water level of one of multiple water tanks and the connector units. With the device, problems of many sensors and solenoid valves are needed to be used, the manufacturing cost is high, the installation wiring is inconvenient, and the system stability is poor and the like when the traditional multi-water tank control way is used can be solved; and the water level control occasion requirement of multiple water tanks, especially the beverage dispenser water level control requirement in a service testing machine of a multi-functional beverage dispenser can be met.
Description
technical field [0001] The invention relates to a water level control device for water tanks, in particular to a water level control device for controlling multiple water tanks. Background technique [0002] Usually, when the water level of a single water tank is automatically controlled, a high limit, a low limit and a normally closed electromagnetic valve are respectively set in the water tank. as attached figure 1 As shown, when the water level is lower than the lower limit SQ1, the solenoid valve YA1 is energized to supply water, and the water pipe 1 enters the water tank 2. When the water level is higher than the upper limit SQ2, the solenoid valve YA1 is powered off, and the water pipe 1 stops adding water. Thereby ensure that the water level of the water tank 2 is within a certain range. [0003] However, in the process of industrial control, the problem of controlling the water levels of multiple water tanks is often encountered. For example, the life tester of a m...
