Abstract
The utility model discloses a large-diameter rotary-wing type digital liquid seal water meter. An impeller box, a gear box and a counter are arranged in the case of the water meter; an impeller inside the impeller box drives the counter, driven by a gear inside the gear box; wherein, the counter is arranged in a transparent liquid seal box filled of cleaning liquid; a seal piece is arranged on a kinematic pair position between the counter and the transparent liquid seal box. When in operation, no matter how big the water pressure outside the transparent liquid seal box is, the utility model can reliably isolate both the internal and the external of the counter so as to completely prevent the counter being polluted by the impurities in the water to ensure accurate measurement and clear reading.
Description
The utility model relates to a kind of water meter that measures discharge in the pipeline, and especially a kind of rotor water gauge belongs to the measuring instrument technical field.
At present, impeller box, gearcase sum counter are housed in the watchcase of known heavy caliber rotor water gauge.Wherein the impeller in the impeller box is driven by the current by pipeline, by the pointer in the drive of the gear drive in the gearcase counter, thus the reading of demonstration discharge.In actual applications, because impeller box, gearcase and reading box do not have reliable seal isolation each other, so the impurity in the water is easy to enter counter, influences measuring accuracy, inconvenient copy reading.Even more serious is that when resuming water supply after the maintenance of cutting off the water, moment, big current were easy to the dirt that is deposited in watchcase bottom and the pipeline is rushed in counter, and counter is polluted, and cannot see display disc, can't reading.In addition, owing to behind watch glasses of fetching boiling water, be easy to stir pointer, therefore steal the water incident and happen occasionally.
The purpose of this utility model is: the problem that exists in using at above-mentioned existing heavy caliber rotor water gauge proposes a kind of heavy caliber rotary wind type numeral liquid-sealing water meter that can avoid counter to pollute.
In order to achieve the above object, in the watchcase of the utility model heavy caliber rotary wind type numeral liquid-sealing water meter impeller box, gearcase sum counter are housed, impeller in the impeller box drives counter by the gear drive in the gearcase, wherein counter is contained in the transparent fluid-tight box that is filled with clean liquid, and seal is equipped with in the motion vice division chief between counter and transparent fluid-tight box.
Owing to be filled with clean liquid in the counter, and between counter and transparent fluid-tight box, seal is housed, therefore the utility model in use, no matter transparent fluid-tight box hydraulic pressure outward is much, all can reliably will isolate inside and outside the counter, thereby thoroughly avoid counter by the contaminating impurity in the water, guarantee accurate measurement, clear reading.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
Among Fig. 1: the 1st, watchcase, the 2nd, flange, the 3rd, gearcase, the 4th, counter, the 5th, cover, the 6th, glass, the 7th, transparent fluid-tight box, the 8th, character wheel, the 9th, O-ring seal, the 10th, impeller, the 11st, impeller box, the 12nd, water strainer.On the watchcase 1 of this heavy caliber rotary wind type numeral liquid-sealing water meter intake-outlet is arranged, impeller box 11, gearcase 3 and transparent fluid-tight box 7 wherein are housed.Be filled with cleaning glycerine in the transparent fluid-tight box 7, and the character wheel 8 of rotating shaft horizontal positioned is housed.Impeller 10 in the impeller box 11 is by the two-stage gear reduction transmission in the gearcase 3, drives the worm gear coaxial with character wheel 8 by final worm screw again, thereby drives the counting character wheel 8 in the transparent fluid-tight box 7.The O RunddichtringO is equipped with in motion vice division chief between the wheel shaft of transparent fluid-tight box 7 and character wheel 8.In addition, be with cover 5 outward on the transparent fluid-tight box 7 of this table, can play the effect of fixing transparent fluid-tight box 7 and glass 6.
When the heavy caliber rotary wind type numeral liquid-sealing water meter of present embodiment has current to pass through in pipeline, impeller 10 in the impeller box 11 is ordered about rotation by current, this rotation is rotated by the character wheel group that gear in the gearcase 3 and final worm screw, worm-drive drive in the transparent fluid-tight box 7, thereby shows the water yield reading that flows through water meter.Owing to be filled with glycerine in the transparent fluid-tight box 7, and the O RunddichtringO is equipped with in the motion vice division chief between transparent fluid-tight box 7 and the print wheel shaft, therefore can avoid into water, thereby guarantee character wheel 8 countings accurately, clear all the time.In addition, because character wheel 8 and drive mechanism with self-locking performance have guaranteed that reading is irreversible, thereby effectively prevented to steal the generation of water incident.This heavy caliber rotary wind type numeral liquid-sealing water meter will effectively overcome the deficiency that existing like product exists, good market prospects after applying.
