Hunan meter meter factory / water company dedicated water / anti-drip meter / price LXSF water-saving drip water meter characteristics: (1) the smaller the initial flow: the initial flow rate is less than 0.5L / h; (2) adaptability to water quality : anti-drip water bodies will not be less than 4mm magazine is clogged or stuck; (3) anti-slip performance: soft diaphragm and anti-drip seal, to offset water hammer pressure, with good anti-slip performance; (4 ) Measurement accuracy: in 0.5L / h ~ 8L / h of the micro-flow state for the intermittent measurement, and this error is smaller trace range. The internal structure of traditional water meter can be divided from the outside shell, sleeve, inner core Big Three. Housing is cast iron, after coming out of the water from the inlet through the lower portion of the casing annular space, here called the "lower ring chamber." In the annular space above the "Sheung Wan room" and outlet connected. Bottom of the sleeve has a filter with holes, debris in the water filtered. There are two rows of the upper and lower sides of the sleeve hole, the hole position coincided with the upper and lower casing annulus chamber facing, obviously, the next row is a water hole, the upper row is the water hole. Of particular note is that the two rows of holes are at an angle in the tangential direction along a circular play. Note that the upper and lower two rows of holes in the opposite direction. Water from the lower row of holes flow into the tangential direction, is bound to a swirling flow, which for water is very important work. The inner core is divided into upper, middle and lower layer, seen from the upper windows, only pointers and dials. Actually, the most critical is lower, and there are two plastic wheels, there are many plastic blade edge, called "impeller impeller location right in the hole formed by the lower casing rotating flow, the current rush week vane wheel produce torque, the impeller spin. faucet open the bigger, the more urgent the water, the impeller to turn faster. impeller shaft vertically upward to reach the middle, there is a small gear shaft above, use it and the "decimal gear" engagement, to achieve the purpose of the cumulative number of revolutions. "Decimal gear" role is to turn every ten laps gear digits, ten-digit gear on the revolution in other words, the single digits gears turn around, ten is the number of gears to turn around. gears are active one digit, tens digit sufficient to drive the gear. virtually every level decimal completion of two pairs of gears to the rotating direction, one of the drive ratio is 9:30 from 10:30 another pair of the two pairs in series, the total transmission ratio is the product of these two, namely 0.099999, can be approximated as 0.1. According to this calculation, you need to read seven number (before the decimal point is read four black mark, after the decimal point is read three red scale), you have to use 12 pairs of gears coupled with some other purpose, in this small space to squeeze the middle axis and 18 34 gears, can also be regarded as high-density installation. With its simple and inexpensive type of water meter can be used in wet environments without the need for long-term maintenance, and do not supply, power does not affect the work of the advantages will still be long term.
