Description
Technical field
The utility model belongs to oblique vane water meter, and it relates to the water meter technical field.
Background technology
Be used at present the to supply water large-diameter water meter of usefulness, great majority are rotary wind type and two kinds of water meters of horizontal spiral type, rotor water gauge remolding sensitivity helical vane type water meter is good, but the pressure loss is big, volume is big, install and maintenance inconvenient.The pressure loss of horizontal helical vane type water meter is little, and volume is little, in light weight, but sensitivity is relatively poor.Though the various performances of vertical helical vane type water meter after this improves all are greatly improved, manufacturing cost is higher.
Summary of the invention
The utility model provides a kind of diagonal impeller direct reading water meter at the deficiency that existing large-diameter water meter exists, and it has improved technology, reaches to reduce production costs and improve purpose such as water meter measurement performance.
The technical solution of the utility model is as follows:
Realize described purpose diagonal impeller direct reading water meter, it includes watchcase, oblique impeller, rectifier, support, filter screen, counting mechanism, watch glasses etc.
Rectifier is installed in the watchcase by support, and screen cover is on rectifier, and tiltedly impeller is installed in the rectifier, tiltedly on the rachis of impeller annulus magnet is housed.The revolution of oblique impeller passes to counting mechanism by annulus magnet and measures, the photo-electronic directly reading sensor is housed in the counting mechanism, be used to read the water yield data on the dial plate, be convenient to realize the network checking meter by directly reading, make water supply department can monitor user's water yield information of water system in real time.
Blade on the described oblique impeller and rachis are for being in tilted layout, and blade is formed by 6～19, and the upstream face of blade and the angle of rachis are between 10 °～40 °.Described rectifier is the taper rectifier, and its rectiblock lower shape is taper, forms by 5～12.Be provided with the fixedly T-slot of adjusting gear in the bottom of taper rectifier.
The utility model has been improved oblique impeller and the rectifier that is used to measure, its Shooting Technique is good, mould is easily manufactured, improved the technology of water meter, reduced production cost, movement is a removable structure, convenient on-the-spot the installation, improved the metering performance of water meter, can realize the network checking meter by directly reading, made water supply department can monitor user's water yield information of water system in real time.
