Technical field
This utility model belongs to measuring instrument technical field, more particularly, to a kind of water meter movement.
Background technology
Water meter movement is the water metering mechanism of water meter, is the most important parts of traditional mechanical water meter, typically by counting
Device assembly, gear case assembly and impeller case assembly composition.The difference of mode of soaking by counter assembly, water meter movement can be divided into wet
Formula movement, fluid-tight movement and dry-type cassette mechanism.
The counter assembly of wet type movement and impeller case assembly adopt gear drive, therefore it is completely submerged in water, flow
Stable performance.Deficiency is the readability that can affect meter reading using the quality of water quality after a period of time.
Fluid-tight movement is by the counter assembly part cleaning liquid-packing in wet type movement, so that meter reading is not
By water quality impact, shortcoming is its complex structure, and installation and removal are difficult.
The counter assembly of dry-type cassette mechanism and tested water isolation, therefore do not affected by suspended impurity in water, so that it is guaranteed that meter
Count the normal work of device assembly and the clear of reading, also will not cause glass because of table internal-external temperature difference as wet type movement simultaneously
Hazing or condense globule etc. below glass affects the phenomenon of water meter copy reading.
The impeller of dry-type cassette mechanism is separated with central gear, and impeller upper end is by magneticss (square or sector electromagnet, column
Magnet ring, is referred to as magnet steel) it is coupled with the magneticss of central gear lower end.When water jet propulsion impeller rotates, by impeller
The magnet steel at end is attracted or repelled with the magnet steel of central gear lower end, drives central gear synchronous rotary, and is counted by center driving
Device record flows through the water yield of water meter.But in water meter high-speed rotation, such as cross current-carrying capacity q4Or peak-peak flow q5When, impeller is permissible
Reach tens revolution per seconds, impeller easily occurs in the motionless de- magnetic phenomenon of high-speed rotation central gear.Water meter takes off magnetic to be meaned
There is deviation in water meter indicated value and actual used water amount, water measurement can therefore and by leakage be counted, and directly affects management of the use of water unit
Income, is likely to encourage the waste of water resource simultaneously.
Water meter movement typically carries the mechanism of regulating flow quantity performance, but the rough regulation side of traditional u-shaped hole or big hole
Formula is easily restricted by working experience.
