Embodiment
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, be fully described by, it is clear that and described embodiment is only the part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Refer to Fig. 1, a kind of tank level control device that the utility model passes through, including controller 1, water pump 2 and put
In the sunk floating-ball level switch 4 in storage tank 3, the sunk floating-ball level switch 4 and water pump 2 pass through conducting wire and control
Device 1 is connected, and 2 import of water pump is connected with running water pipe 5, and 2 water outlet of water pump is connected with storage tank 3,3 water outlet of storage tank
Mouth is connected with equipment, and the floating ball of the sunk floating-ball level switch can float with the height of liquid level, sunk floating ball liquid
Bit switch gathers liquid level signal by electrical signal collection device, sends signal to controller, and then control water pump by controller
Start and stop, liquid level carry out moisturizing into storage tank in time less than setting value.
As a kind of preferred structure, the sunk floating-ball level switch 4 is set through the top of storage tank 3, and the storage tank 3 pushes up
Portion is equipped with mounting blocks 6, and the top of sunk floating-ball level switch 4 is arranged on mounting blocks 6, and the sunk Floating Ball Liquid Level is opened
