Abstract
The utility model discloses the quantity of a water metering controller, comprising a comparator, a counter, a driver, etc. Water drives a rotor or a worm wheel to rotate via a sensor, and thus continuous electrical pulse signals can be sensed via a hall device. Cumulative digits are output by a calculator in the mode of two paths; one path is sent to a digital display unit for carrying out the displaying of water quantity, and the other path is sent to the comparator and compares with the manual setting value of a digit given dial switch. The comparator send out signals to control an electronic switch for pushing the electromagnetic valve. The utility model adopts an electromechanical integral structure and has small size and light weight, and the utility model is suitable for portable use in industrial on site.
Description
The utility model relates to the quantitative controller of the water yield.
In building, industries such as food processing, medicine, light industry, chemical industry, pottery all need output is carried out on-line measurement and quantitatively control.Under present existence conditions, output is measured and quantitatively controlled all and need four parts form by flowmeter, flow integrator, controller and electronic or pneumatic valve as need.The water yield quantitative control system one of Zu Chenging is that complex structure, system are huge like this, all brings inconvenience for setter and user; The 2nd, the cost height.And building trade the more portable collection of active demand measure, show and be controlled in the quantitative controller of the online water yield of one.
The purpose of this utility model provides a kind of water yield quantitative controller.
Be illustrated below in conjunction with accompanying drawing.
Fig. 1 is the quantitative controller block diagram of the water yield;
Fig. 2 is the electrical schematic diagram of the quantitative controller of the water yield.
When current are flowed through sensor T by water inlet after, under the impact of current, drive rotor or turbine rotation, by little magnet steel is housed thereon, thereby induce continuously electric impulse signal at hall device, counter just carries out stored counts to this pulse signal, counter divides two-way output with cumulative number, and one the road delivers to digital display unit carries out water yield demonstration; Comparator and digital given unit dial switch K are delivered in another road1K
2On setting value compare, when setting value equated with water yield accumulated value, when namely comparator two ends numerical value was identical, comparator just sent signal controlling electronic switch S, closes electromagnetic valve V, finishes the requirement of quantitative water supply.
Circuit shown in Figure 2 is that the double figures code shows, such as need long number more, namely to the survey of the water yield, when the control area requirement is bigger, but cascade more the number of long number show.
