The mechanical water meter accurate to meter is simple in structure, small in using errors and capable of accurately metering passing water, so that economic loss is reduced and needs of people's production life are met.
Description
Technical field
The present invention relates to a kind of water meter, especially relate to the accurate mechanical water meter of a kind of counting, belong to life mechanical field.
Background technology
Water meter is the instrument of measuring discharge.The integrated flow that is mostly water is measured.Generally be divided into volumetric water meter and velocity type water meter two classes.The former accuracy is high compared with the latter, but high to water quality requirement, easily blocked when impure in water.Record the instrument of tap water water consumption, be contained on water pipe, when user discharges water, on table, the water yield of passing through is pointed out in pointer or character wheel rotation.
Since having invented the balance pot type water meter really with instrument feature from the Ke Lusi of Britain in 1825, the existing nearly bicentenary history of the development of water meter.The water meter of China uses and production is started late.1879, Li Hung-chang, for making arrangements of naval, created China first hand water factory at Lvshun mouth.Within 1883, English colonialist has set up second water factory in Shanghai, and water meter starts to enter China.Along with water factory is built in some coastal cities in succession, to 20 generations in centurial year, Shanghai brilliance machine works at that time (now Guanghua Instrument and Meter Plant predecessor) etc. produces water meter from external inlet part part.In considerable time, the water meter of the country such as Great Britain and France's day moral is always in occupation of Chinese water meter industry, these different cultivars, the water meter that specification is numerous and diverse, because standard differs, part can not exchange, brought very large difficulty to the water meter maintenance of later Running-water Company.1949 after liberation, and along with the development of urban water supply cause, the water meter industry of China also correspondingly grows up.From nineteen fifty-five, the city tap-water companies such as Shanghai, Beijing, Tianjin, Nanjing, Wuhan, Guangzhou successively start to produce water meter.Early 1980s, water meter industry is under Shanghai City industrial automation instrument research institute of Ministry of Machine-Building Industry tissue, according to the requirement of water meter international standard ISO4046 at that time, small diameter watermeter has been released again to the water meter of the national Uniting of eight bit pointers, integral wheel.The plastic of Uniting and water meter parts, for organizing specialized production of water meter to create favourable condition, promotes Chinese water meter industrial progress and development greatly, has met growing town and country tap water industrial expansion demand.Mechanical water meter on market, due to the complex structure of its design, has caused error large now, inaccurate to the measurement of the water yield.
Summary of the invention
The object of the invention is to overcome the complex structure of existing water meter, caused error large, to the inaccurate problem of the measurement of the water yield, designed the accurate mechanical water meter of a kind of counting, this water meter simple in structure, use error is little, can accurately measure the water yield of passing through, reduce economic loss, met the needs of people's productive life.
Object of the present invention is achieved through the following technical solutions: the accurate mechanical water meter of a kind of counting, the housing that comprises inner hollow and an end opening, described enclosure interior is provided with scale, scale be arranged on openend under, scale below is provided with several intermeshing reduction gearing, reduction gearing below is provided with turning axle, the top of turning axle is passed one of them reduction gearing and is fixed with this reduction gearing, on the outer wall of turning axle, be fixed with several impellers, impeller is uniformly distributed around the axial line of turning axle.
Further, the two ends of described housing are provided with water inlet pipe and rising pipe, and water inlet pipe and rising pipe are communicated with enclosure interior respectively.
Further, described reduction gearing, turning axle and impeller are all arranged on enclosure interior.
Further, on described scale, be provided with water flow meter, water flow meter is connected with turning axle.
Further, be provided with several counters on described scale, and counter is evenly distributed on the surrounding of water flow meter, each counter is all connected with reduction gearing.
Further, the openend inside of described housing is provided with division board, and the surrounding of division board and the openend of housing are tightly connected; The openend top of housing is provided with case, and case is fixed on housing by bearing pin, and case can rotate around bearing pin.
In sum, the invention has the beneficial effects as follows: this water meter simple in structure, use error is little, can accurately measure the water yield of passing through, and has reduced economic loss, meets the needs of people's productive life.
