Description
Technical field
The utility model relates to a kind of electric device of water level control.
Background technology
Present water level control electric device, generally be to adopt height utmost point bar to survey water level or utilize the ball float lifting in the water to survey water level, and cooperate electric device to be achieved, its shortcoming is that utmost point bar will adopt white steel metal material to make, and cost is high and be not suitable for using in acid-base solution, can not be used for high temperature, occasion that steam is big is used, the electric control circuit complexity, water vapor is easy to make the conducting of high water stage contact, thereby causes water pot to dryout, damage equipment; Adopt ball float to survey water level, need to use lever mated, volume is big, and the contact limit switch is used the failure rate height.Above factor has all restricted production greatly.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of reasonable in design, cost low, the electric device of the water level control that failure rate is low.
In order to address the above problem, the utility model by the following technical solutions:
A kind of electric device of water level control, comprise container, container holder, water inlet pipe and rising pipe, container is installed on the container holder, water inlet pipe is installed in container head, rising pipe is installed in the container lower end, container is provided with water level gauge outward, the water level gauge lower end communicates with container, container outer wall is provided with support, water level gauge is by the support fixed support, the support top and bottom be respectively equipped with high water stage near switch and low-water level near switch, high water stage links to each other with control box respectively near switch with low-water level near switch, control box links to each other with solenoid valve.
Described water level gauge comprises glass tube and ball float, and glass tube communicates with container, and floating ball diameter is less than diameter glass tube and be contained in the glass tube; Described ball float is hollow Metal Ball.
Compared with prior art, the beneficial effects of the utility model are:
1, will survey in the water gauge glass that ball float places water receptacle, ball float is lifting along with the height of water level, and volume is little, observes intuitive and convenient.
2, adopt near inductive switching metal ball float, thus the control inflow, and failure rate is low, and is durable in use, for enterprise has saved maintenance cost.

Embodiment
A kind of electric device of water level control, as shown in Figure 1, comprise container 1, container holder 2, water inlet pipe 8 and rising pipe 10, container 1 is installed on the container holder 2, water inlet pipe 8 is installed in container 1 top, and rising pipe 10 is installed in container 1 lower end, the container 1 outer water level gauge that is provided with, water level gauge comprises glass tube 4 and ball float 5, and ball float 5 adopts hollow Metal Ball to make.Glass tube 4 lower ends communicate with container 1, and ball float 5 diameters are less than glass tube 4 diameters and be contained in the glass tube 4.Container 1 outer wall is provided with support 3, water level gauge is by support 3 fixed supports, support 3 top and bottom be respectively equipped with high water stage near switch 6 and low-water level near switch 7, link to each other with control box respectively near switch 7 with low-water level near switch 6 near high water stage, control box links to each other with solenoid valve 9, is provided with switch shown in Figure 2 and contactor in the control box.When metal hollow ball float 5 near high water stage near switch 6 or low-water level during near switch 7, high water stage can move near switch 7 near switch 6 or low-water level, and then the switch of control electromagnetic valve 9.
In the container 1 of the electric device of water level control water is housed, when water level raise, metal hollow ball float 5 was along with rising, when ball float 5 was raised to setting high-order, high water stage was sensed ball float 5 near switch 6, and high water stage is near switch 6 actions, solenoid valve 9 cuts out, and stops moisturizing, and water flows out along rising pipe 10; When water level was reduced to the low level of setting, ball float 5 was along with decline of water table, sense ball float 5 after, low-water level makes circuit working near switch 7 actions, solenoid valve 9 is opened, and continues moisturizing.
Circuit control principle of the present utility model is:
Selector switch SSA is provided with manually and automatic two gears.
When manually control added water, SSA moved manual gear to selector switch, as shown in Figure 2, presses manual actuation of button SB, then contactor K get electric, probe of contactor action, i.e. K1, K3 closure, K2 disconnects, D1 is bright for the moisturizing pilot lamp, and solenoid valve 9 gets electric opening, the beginning moisturizing.When metal hollow ball float 5 rises to high water stage near the height of switch 6 with water level, stop moisturizing K switch 12 and disconnect, contactor K dead electricity, then K1, K3 disconnect, the K2 closure, it is bright to stop moisturizing pilot lamp D2, and solenoid valve 9 dead electricity are closed, and stop moisturizing.
When control adds water automatically, move selector switch SSA to automatic gear, as shown in Figure 2, when water level dropped to low-water level, low-water level was moved near switch 7, moisturizing K switch 11 closures, and contactor K gets electric, and K4 is from mending, and solenoid valve 9 is opened, the beginning moisturizing; When water level water level raising during, K12 action near switch 6 positions, the K dead electricity, solenoid valve 9 cuts out, and when water level reduces by the time, carries out next round-robin work.
