Abstract
The utility model discloses a wide-range household water meter, which comprises a case and is characterized in that a large flow metering mechanism and a small flow metering mechanism are arranged inside the case simultaneously and are connected with controlling valves, the controlling valves are connected with a flow value recognizing modules, and the flow value recognizing modules are used for collecting a water flow signal and controlling the controlling valves to open a proper metering mechanism according to the flow signal so as to achieve the alternating working of the large flow metering mechanism and the small flow metering mechanism. Compared with the prior art, the water meter adopts the controlling valves to open the proper metering mechanism, the flow value recognizing modules are used for collecting the water flow signal and controlling the controlling valves according to the flow signal, however, the open of the valves is not required to be achieved by a water flow impact force, the pressure loss is low in the switching process of the controlling valves, and a clamping situation never occurs.
Description
Technical field
The utility model relates to a kind of wide-range family and uses water meter, belongs to the technical field that fluid flow detects.
Background technology
In short supply day by day along with global freshwater resources seems particularly important to the accurate metering and the management of water consumption.Water meter is as the important measurement instrument of water consumption; Its metering accuracy, measurement range degree, dependability, life-span and function and manufacturing cost etc. all are related to it in water metering and water rate clearing, and the use value of aspects such as control water, using water wisely and management of the use of water.But existing water meter only just can measure when the pressure differential of Inlet and outlet water reaches certain numerical value, when the part resident adopts crack water valve, steals water through dripping, and causes great lot of water resources by use without compensation, brings about great losses to country.
In order to change above-mentioned situation, there is the people this to be made improvement, adopt the form of primary and secondary table to make water meter can realize that the metering of big flow also can realize the metering of low discharge.It like application number 200510015777.6 Chinese utility model patent; It discloses a kind of device for preventing water burglary of drip, and it comprises the big water meter of wet type rotary wind type, uniaxial pressure stop valve, the little water meter of wet type rotary wind type, and little water meter is identical with big water meter structure; The water pipe two ends that string is provided with little water meter are attempted by the water pipe two ends that are connected in series through pipe adapter by uniaxial pressure stop valve and big water meter respectively; The uniaxial pressure stop valve has upper and lower two chambers, and valve seat is fixed in upper chamber, and the valve rod front end that is socketed with pressure spring in the valve seat is connected with spool; The central lines of through hole between the center line of spool and upper and lower two chambers, the water inlet port of little water pipe is bonded with screen pack.
Secondly but also there is following shortcoming in above-mentioned mechanical type primary-secondary type water meter: the pressure loss is big in the use, and the more situation lower valve of impurity blocks easily in current, makes that water meter in use for some time can't operate as normal, influences the metering of water meter.
Summary of the invention
The utility model is to deficiency of the prior art, the no pressure loss in a kind of simple and reasonable, use is provided and water meter is used at the wide-range family that is difficult for blocking.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: water meter is used at a kind of wide-range family; Comprise housing; It is characterized in that: be provided with large capacity meter measuring mechanism and small flowmeter measuring mechanism in the said housing simultaneously; Said large capacity meter measuring mechanism and small flowmeter measuring mechanism are connected with operation valve, and said operation valve is connected with the flow value identification module, and said flow value identification module is used to collect water flow signal and controls said operation valve according to this flow signal and open suitable metering mechanism to realize said large capacity meter measuring mechanism and the alternation of small flowmeter measuring mechanism.
Compared with prior art; The utility model adopts operation valve to open suitable metering mechanism; Owing to be to collect water flow signal and control said operation valve according to this flow signal through the flow value identification module; Do not need to rely on water flow impact pressure to open valve like prior art, operation valve pressure loss in transfer process is little, and the situation that can not occur blocking.
As a kind of attainable scheme, above-mentioned large capacity meter measuring mechanism and small flowmeter measuring mechanism are two kinds of different types of metering mechanisms.
As preferably, above-mentioned large capacity meter measuring mechanism and small flowmeter measuring mechanism are respectively Ultrasonic water meter and jet stream water meter.
The utility model compared with prior art; Have following beneficial effect: the utility model adopts operation valve to open suitable metering mechanism; Owing to be to collect water flow signal and control said operation valve according to this flow signal through the flow value identification module; Do not need to rely on water flow impact pressure to open valve like prior art, operation valve pressure loss in transfer process is little, and the situation that can not occur blocking.
