Its structure is simple and reliable.
Description
The present invention relates to the flow metering field, mainly propose a kind of non-metering electronic digital type drop of micrometeor drop flowing water metering water meter of stopping.
Present known water meter is to adorn a rotor blade and gear counter in housing, and the water impact rotor blade rotation of intake gauge drives the numeration of speed gear speed change, and demonstrates the quantity of discharge, and current flow out from water delivering orifice and use for the people then.Because structural principle, rotor blade can not rotate under this structural type water meter micrometeor, can not measure.Now generally produce the rotor wet type A type water meter that uses and be example with China: the water meter of GB specified diameter 20MM, initiating flow be 60L/H promptly per hour the following water meter of drop flowing water 60Kg can not measure.Calculate with this, every day micrometeor more than one ton water meter do not measure.TV station of central authorities reports according in August, 2000: the water rate loss that the annual drop in Shanghai (micrometeor) can not measure is about 100,000,000 yuan.As seen improve water meter structure technically and eliminate the initiating flow, be very important.
In order to overcome the existing non-metering defective of water meter drop flowing water, the invention provides a kind of electronic digital type drop metering water meter.
The objective of the invention is by providing a kind of water meter to realize with following structure.This water meter comprises: the drop ponding device that housing, worm gear sensor, worm gear pulse signal generator, rechargable power supplies, counter master chip CPU, counter display and integration piston cylinder, edge permanent magnet ring piston are formed, and the envelope pin of edge permanent magnet ring piston, edge permanent magnet, the reverse stop valve of permanent magnetism formed by valve plug, integrator valve plug sealing ring.Having upper water that the intake tunnel that interconnects is arranged in housing on the described housing flows to turn 90 degrees down and bends from the parallel outflow of lower floor's exhalant canal.Housing left end (water inlet end) is the pipe shape, the two bearings bearing of edge bearing in put at the circle center; Supporting the wormwheel blade of rotating band central shaft between the diaxon bearing, its wormwheel blade top embedding pulse signal generator is aimed at the pipe shape housing of pulse signal generator and is disposed the pulsed signal device, and CPU connects with lead sum counter master chip.Rechargable power supplies is the register power supply, is communicated with lead and powers to counter master chip CPU.Counter number display screen sum counter master chip CPU connects with lead, and the quantity of calculating promptly shows on display screen.The Inlet and outlet water dividing plate is established at 90 degree turnings in described housing right side, and the flowing water circular hole is established at this plate center, and the vertical installation in its upper surface, hole is cylindric by valve plug, described plug lower step place edge sealing side circle, and the flowing water through hole is put at round vertically center.It on same axis of end face center hole, lays the Long Circle envelope pin that make for circle pinnacle shape non-magnet material edge permanent magnetic iron pole lower end, upper end beyond the Great Wall
The guiding spacer sleeve that pipe shape non-magnet material is made, coaxial cable are sleeved on the edge permanent magnet and seal outside the pin, and its cover internal diameter is edge permanent magnet envelope pin energy bob, and this cover bilateral and shell down connects together, and is the part of housing.Along guiding spacer sleeve longitudinal center line at the outer coaxial cable suit edge of its cover permanent magnet ring piston, piston lower end concentric mounted permanent magnet ring also and piston connect together.Its piston neighboring is at correct position dress O type sealing ring, and slipper seal is contained in the ponding piston cylinder.Dress knock-on spring between described edge permanent magnet ring piston upper surface and the ponding piston cylinder Nei Ding lower surface.Its ponding piston cylinder following peripheral and shell connect together, by water pipe bottom Inlet and outlet water in piston cylinder.
Electronic digital type drop flowing water metering water meter of the present invention, compared following advantage with the water meter of prior art: original water gauge does not measure (stipulate by GB as rotor 20A level water meter: the initiating flow is 60Kg/H per hour) when the initiating flow is following.Electronic digital type drop flowing water metering water meter of the present invention can amass drop flowing water when micrometeor, concentrate to discharge to flow out metering.When big flow, rotate by the worm gear sensor and to send the signal metering.
Embodiments of the present invention are described below with reference to accompanying drawings:
