Description
Technical field
This utility model relates to intellectual water meter, particularly relates to a kind of highly sensitive anti-rotation remote transmitting water meter.
Background technology
Highly sensitive water gauge in the market, is made up of two water channels, when low discharge, under movement, inlet valve is closed, and current are flowed into by water strainer and impeller box water channel, and current are directly got excited impeller, make wheel rotation reach the purpose to tiny flow quantity metering, thus improve water meter measurement sensitivity.When big flow, bottom valve gap is opened by bourn acting force, and current have drainage screen bottom to intake, to meet big flow water.
The problem that this kind of highly sensitive water gauge exists is mainly manifested in the use of market, owing to environment is different, application scenario is different, water meter is widely present the water meter rotation phenomenon without water, the reason causing water meter rotation has: there is gas in water supply network or because of water heater, solar water heater hot water return causes, but it is unstable that main cause is pressure of supply water, pressure of supply water fluctuates, owing to water meter measurement is highly sensitive, it is very sensitive to the pressure oscillation in water supply network, particularly high-rise building second pressure water supply, in water supply line, owing to pipeline pressure is higher, water meter reveals certain compressibility.When pressure oscillation change in pipe network, causing volumetric expansion and the compression of water, when pressure raises, after table, the water volume in pipe can be compressed because pressure raises, and the most just has a small amount of water by water meter, generation rotation；When pressure decreases, discharged by the compression water yield, have a small amount of water equally and pass through water meter, as long as thus water pressure fluctuations is once, water meter will dally once, although one time water pressure fluctuations water meter will not dally how many, but water pressure fluctuations can cause user's water meter to dally in a large number frequently, and the water consumption error of metering will be bigger.Therefore, cause user's suspection to water meter measurement, cause dispute, produce client and refuse to hand over the new problems such as water rate, bring difficulty to administration section.
The method solving water meter reversing at present is to install check-valves, and the method installing check-valves is: installs check-valves before table, stops current backflow after table, thus solve water meter rotation, in real operation, there is rebuilding construction difficulty, the problems such as improvement cost is high.Another kind of method is installation check-valves in connecting pipe of water meter, this kind of method is simple to operate, but have a problem that, owing to being mounted in connecting pipe of water meter, cause supply channel necking down, supply channel area is made to reduce, thus in connecting pipe of water meter, produce the pressure loss, before making table, pressure of supply water reduces, and affects user's discharge, when pressure of supply water is too low, cause user cannot use water.
Utility model content
The purpose of this utility model is to be to overcome the deficiency in above-mentioned prior art, and provides a kind of simple and reasonable, prevents the highly sensitive anti-rotation remote transmitting water meter of water meter rotation
nullHighly sensitive anti-rotation remote transmitting water meter of the present utility model，Including: the integrated shell body of water meter valve、Highly sensitive anti-rotation water meter movement、Valve drives reducing motor、Flow transducer、Electronic module、Battery and M-BUS，Highly sensitive anti-rotation water meter movement record water consumption，The machinery water yield is converted to the signal of telecommunication and is transferred to electronic module by flow transducer，Calculated by CPU、Storage、Display water consumption，And timing uploads to management of the use of water terminal，Described highly sensitive anti-rotation water meter movement includes: impeller box、Piston sheet、Filter cartridge，Piston sheet is arranged on filter cartridge inner bottom part and has one-way conduction function，Impeller box is divided into、In、Lower three parts，Top is provided with outlet，Bottom is provided with water inlet，Mid portion is upper and lower two bulge loops，Upper bulge loop lower wall fits with described filter cartridge mouth upper surface，Lower convex ring four perisporium fits with described filter cartridge inwall，The box wall of impeller box bottom is provided with pod apertures，Check-valves placing chamber it is provided with in pod apertures duct，In check-valves placing chamber, check-valves is installed，Described check-valves includes spring and non-return valve plug，Spring one end is fixed on check-valves beyond the Great Wall，The other end of spring is fixed on the end of check-valves placing chamber one end，Corresponding with non-return valve plug，When the hydraulic pressure in impeller box is more than or equal to the hydraulic pressure outside impeller box，Non-return valve plug blocks the water conservancy diversion aperture of impeller box outer wall one end，When the hydraulic pressure outside impeller box is more than the hydraulic pressure in impeller box，Non-return valve plug is opened water conservancy diversion aperture because spring is compressed，Water flows into impeller box.
The one end in described non-return valve plug contact water conservancy diversion aperture is sphere.
Experiment shows: as the spring constant K=637.76g/mm of check-valves, and when diameter, length, line footpath are respectively 4.5mm, 5mm, 0.5mm, effect is best.
The chip of described electronic module is MSP430F413/TSS721A.
The model of described battery is CR17450.
Described highly sensitive anti-rotation water meter movement also includes gearcase, is provided with multiple aperture bottom gearcase, it is simple to the water of residual in water meter after getting rid of water meter verification or checking.
It is groove type drainage screen in the middle of bottom described filter cartridge, the filtration network interface periphery of filter cartridge bottom interior surface has been evenly arranged 25 leads, the breach being formed around coordinating with lead of piston sheet, the bottom of described impeller box props up the top of lead, so that piston sheet has one-way conduction function well.
Water meter of the present utility model is made up of two water supply loops, one is: when user opens faucet tiny flow quantity water, water supply loop non-return valve plug is opened, current flow into impeller box by pod apertures, apply power, wheel rotation to impeller, driven gear rotates, thus realizing water metering so that water meter measurement is highly sensitive, plays drip-proof effect.Two are: when user's Open valve enlargement discharge, and current pass through drainage screen, open valve gap and enter impeller box, impeller, gear drive, it is achieved water metering.
When in user's unused penstock closed mode, if in pipeline, water pressure fluctuations increases before occurring table first, current are first turned on non-return valve plug, current flow into impeller box, water meter can dally, when hydraulic pressure reduces, piston sheet in hydraulic pressure and acting force of the spring are applied concurrently to non-return valve plug and impeller box in water meter, make non-return valve plug, piston sheet is closed and applies certain pressure, in making table body and after table, in pipeline, current cannot reflux, so that water gauge body is interior and after table, supply channel remains water supply loop maximum pressure, if in pipeline, water pressure fluctuations increases before again there is table, because of its pressure balance or less than pressure in table body, do not result in non-return valve plug and piston sheet secondary is opened, current will not enter in table, water meter would not dally again, thus keep water meter stability.When user's generation water, in table body and circuit pressure release after table, water meter recovers normal operating conditions.
Experiment shows: the present invention both can guarantee that the sensitivity of water meter, can prevent again water meter from dallying, and in water meter working pressure range, metered pressure loss, less than 0.063MPa, meets GB GB/T 778.1 standard-required.And, simple in construction, original production equipment only need to simply be transformed by Producer just can produce the impeller box with check-valves of the present utility model, and input cost is low.
