Problems solved by technology

[0002] There are two types of commonly used water meters, wet type and dry type. The wet type gear is in the water, and the measurement accuracy is affected by the resistance of the water. The impurities and rust in the water affect the gear rotation, resulting in inaccurate measurement. Affect the rotation of the impeller under the micro-flow, the friction resistance of each wheel shaft of the mechanical counter, and the micro-flow meter often does not work, resulting in stealing and wasting water

Abstract

A water meter of drop-proof and reverse-proof as well as detachable-proof type is forming check valve mechanism by shell, check valve base, spring, etc; forming double metering impeller driving mechanism by water-proof isolation plate, driving wheel magnetic ring, impeller shaft, etc; forming independent sealed meter cavity isolated to mechanism water meter counter by detachable proof interlock ring, magnetic proof isolation plate, base plate, etc. It features that magnetic force driving between said impeller and said counter is provided by magnetic rings of metering impeller shaft and synchronous driving shaft.

Description

technical field [0001] The invention relates to a water meter which is anti-drip, anti-reversal and anti-disassembly. Background technique [0002] There are two types of commonly used water meters, wet type and dry type. The wet type gear is in the water, and the measurement accuracy is affected by the resistance of the water. The impurities and rust in the water affect the gear rotation, resulting in inaccurate measurement. It affects the rotation of the impeller under the micro-flow, the friction resistance of each wheel shaft of the mechanical counter, and the micro-flow meter often does not work, resulting in stealing and wasting water. Contents of the invention [0003] The object of the present invention is to overcome the above defects and provide a water meter that is anti-drip, anti-reversal, and anti-disassembly. [0004] The technical solution of the present invention is, a water meter that is anti-drip, anti-reversal, and anti-disassembly, including a check v...
