Description

A kind of Intelligence Water Level Controller

Technical field

The utility model belongs to electrical control equipment manufacture field, more particularly, to a kind of Intelligence Water Level Controller.

Background technology

Water level controller is applied in the equipment such as boiler, water tank, for measuring water level height, realizes that low water level increase is entered Water, high water level stops the controller of water inlet.Current water level controller, come the more of controlling water level, typically has by float switch Two ways, it is a kind of be float switch with a big metal ball, buoyancy is big when soaking in water, can control two water levels, Water, which has expired ball float, can drive valve motion, close valve, stop water inlet；Water has lacked ball float descent tape movable valve opening, then Water inlet, so circulation.This mode accuracy is than relatively low, it is impossible to realize accurate control.Another way is that the lifting of ball float can To be converted into electric signal, and then the switch of water pump is controlled, but precision is not also high under this mode, it is impossible to excessive low water level protection is realized, is led Water pump during water shortage is caused to dally, energy consumption increase reduces the service life of water pump simultaneously.

Therefore, important function of the water level controller in actual production is taken into full account, the precision of level measuring is improved, it is ensured that Pump trip when can open pump, high water level automatically in low water level, and with excessive low water level protection function, prevent water pump from dallying, drop Low energy consumption, with reference to the service condition and operation principle of current water level controller, inventor have developed one with reference to experience Plant Intelligence Water Level Controller.

The content of the invention

The utility model purpose is in view of the deficienciess of the prior art, proposing a kind of reasonable in design, safe ready, survey Accuracy of measurement is high, the Intelligence Water Level Controller with low water level automatic start water pump, the function of high water level pump trip.

The purpose of this utility model can be realized by following technical proposal：

A kind of Intelligence Water Level Controller, the Intelligence Water Level Controller includes external shell, peace and turned in the metal spiral shell on housing Line interface and Intelligence Water Level Controller body, it is characterised in that：The Intelligence Water Level Controller body interior is additionally provided with defeated Enter to terminate at the pressure sensor of described metal threaded interface one end, the filter circuit of the connection pressure sensor output end, MCU microprocessors that input is connected with the filter circuit output end, input connect the MCU output end of microprocessor Indicating lamp module, the display of the connection MCU output end of microprocessor and the connection MCU microprocessor inputs Key-press module；

Wherein, alarm lamp and run indicator are additionally provided with inside the indicating lamp module.

The key-press module includes excessive low water level protection set key, stopping water level set key, priming level set key and operation On ＆ off switch.

The utility model has an advantageous effect in that：The Intelligence Water Level Controller is easy for installation, can carry out high-precision Level measuring, the function with low water level automatic start water pump and high water level pump trip, and can be prevented in water shortage Water pump dallies, and reduces energy consumption.
