Description
(1) technical field
The utility model relates to a kind of measurement instrument of fluid, particularly a kind of utensil that can measure the fluid that drop flows.
(2) background technology
Present known water meter is to adorn a rotor blade in the enclosure, and the water impact rotor blade rotation of intake gauge drives speed gear speed change counting, and shows the flow by the water of water meter.Owing to rotor blade under this structural type water meter micrometeor of reason of structural principle can not rotate, can not measure.Now the KHM II type dry type digital water meter of producing with the Japanese Jinmen of recent introduction Co., Ltd. state-of-the-art technology is an example: the water meter of technological document specified diameter 25MM, flow are that 20L/H per hour is that the following water meter of drop flowing water 20KG can not measure.Calculate the nearly half ton water of miniflow every day with this, and water meter can not measure.Report the CCTV according in August, 2000: the water consumption loss that the annual drop in Shanghai can not measure is about 100,000,000 yuan, and as seen necessary technically improvement water meter structure reduces the initiating flow.
Because existing water meter can reverse when reverse, therefore give the water-robbery person in addition with opportunity.
(3) summary of the invention
[problem that will solve]
The utility model provides a kind of intelligent telemetering to control the measurement basis water meter that drips, and first problem that its solves is that rotor blade can not rotate under the existing water meter micrometeor, the problem that can not measure; Second problem that its solves is existing water meter reversible problem when reverse.
[technical scheme]
The utility model intelligent telemetering is controlled the measurement basis water meter that drips and is included watermeter shell 1, be arranged on watermeter shell 1 water inlet end watermeter shell 1 is divided into before and after chamber and permanent magnetism that can unidirectional unlatching under the impact of current isolate retaining valve 3, be arranged on the measuring apparatus that has rotor blade 2 in the back cavity, expansion standpipe 4 that is connected with watermeter shell 1 water delivering orifice or slip water storage cylinder 8/9 and outside its standpipe 4 suit two halves circles adjust pipe 5, adjust moisture storage capacity by adjusting bolt 6.
Its course of work is: utilize the pressure reduction principle in the leading chamber, front and back that forms of dripping, permanent magnetism is isolated retaining valve open the impact blade rotation fast, standpipe expansion water storage makes it to expand, behind the hydraulic balance of chamber, front and back, the unidirectional isolation valve of permanent magnetism returning quickly under the adhesive of magnetic force is closed, and makes it to form the independent water amount of being interrupted.Long-pending point drips to concentrate to discharge and promotes the purpose that the metering water meter blade rotation reaches metering.The thickness control expansion standpipe moisture storage capacity of adjusting two semicircles adjustment pipe simultaneously makes it accurate measurement.
Isolate retaining valve owing in watermeter shell, add permanent magnetism, therefore make water meter can not reversely cross water.
[beneficial effect]
The drip advantage of measurement basis water meter of the utility model intelligent telemetering control is: first has realized the metering of micrometeor, the simple dependable performance of small volume structure, and second guarantees irreversiblely to flowing water, has avoided the stolen water phenomenon.
