The object of the invention is to overcome the shortcoming of prior art, provide a kind of and can measure the photoelectric direct-reading water meter that the ratio of low discharge, Q3/Q1 more can reach 160 times of above wide-ranges.
Object of the present invention is achieved through the following technical solutions: a kind of photoelectric direct-reading water meter of wide-range, it comprises counter, gearcase, impeller and impeller box, the middle part of impeller box is provided with cavity, gearcase is installed on the top of impeller box, the bottom surface A of gearcase is positioned at the cavity of impeller box, the bottom of impeller box and top offer respectively water inlet and water delivering orifice, and the bottom of impeller box is provided with eight water inlets, and the top of impeller box is provided with four water delivering orifices; The bottom surface A of gearcase is provided with four～six roots of sensation deceleration stem A, deceleration stem A is for radially extending, be arranged at the raised line on the A of bottom surface along gearcase, the bottom surface B of the cavity of impeller box is provided with six～eight deceleration stem B, and deceleration stem B is for radially extending, be arranged at the raised line on the B of bottom surface along impeller box.
Described deceleration stem A is circumferentially uniformly distributed along gearcase, and the height of deceleration stem A is 3～4mm.
Described deceleration stem B is circumferentially uniformly distributed along impeller box, and the height of deceleration stem B is 3～4mm.
Described water inlet is circumferentially uniformly distributed along impeller box, and the horizontal section of water inlet is rectangle, and the distance of water inlet distance impeller box center line in parallel is 18～19mm.
Described water delivering orifice is circumferentially uniformly distributed along impeller box, and the horizontal section of water delivering orifice is rectangle, and the distance of water delivering orifice distance impeller box center line in parallel is 15～16mm.
The present invention has the following advantages: water inlet of the present invention is set to rectangle, and the distance of the impeller box center line that water inlet distance is in parallel is 18～19mm, increased the impulsive force of fluid to impeller, in the time of can guaranteeing that even discharge is very little, current also can directly enter cavity and promote wheel rotation, thereby realize, measure more low discharge; On the bottom surface B of impeller box cavity and gearcase bottom surface A, be respectively equipped with deceleration stem B and deceleration stem A, slow down when impeller is rotated by water impact stem B and deceleration stem A adjusts wheel speed, realize the accurate measurement of each flow point, thereby improved the precision of water meter measurement, the ratio of Q3/Q1 can reach more than 160; When thereby the sectional area that four uniform designs of water delivering orifice have increased water delivering orifice has guaranteed large flow, fluid is more unobstructed.
