Technical field
The utility model belongs to water flow measurement technical field, more particularly to a kind of multistream water meter.
Background technology
Water meter is the instrument for measuring water-carrying capacity.Water meter is generally divided into single channel table and more water stream tables, single channel water meter
Operation principle is：Current are allowed to rotate from watchcase water inlet tangential impact impeller, are then continuously recorded by gear reduction
The revolution of impeller, so as to record the integrated flux for flowing through water meter.The operation principle of multistream water meter and the basic phase of single channel water meter
Together, it is the distributional effects by impeller box, the water inlet tangential impact impeller by multi beam current from impeller box, makes current to leaf
The axial impact force of wheel is balanced, and reduces the abrasion of impeller supporting part, and water pump composite, fouling pair are reduced from structure
The influence of water meter error, overall performance is apparently higher than single channel water meter.
Following defect be present in existing more water stream tables：
（1）More general small volumes of water stream table, watchcase cavity diminish, when water meter operates in big flow, due to cavity
Diminish, cause the water for flowing through housing to be easier that turbulent phenomenon occurs, not only influence the rotation of impeller box intra vane, and current exist
Intracavitary aggregation is not easy to discharge, and directly affects the reading intensive reading of dial plate；
（2）More water flow velocity tables employ the design of impeller box, and blade design is also more complicated, therefore higher to water quality requirement,
Be not suitable for the more area containing impurity such as dirts to use.
