Description
Technical field
The utility model relates to the water meter technical field, particularly a kind of impeller box of wide-range photoelectric direct-reading water meter.
Background technology
Photoelectric direct-reading water meter is a kind of directly reading, can realize again the water meter of remote meter reading, and this water meter reading is convenient, and reliable reading is accurate, and at present, the property plots, industrial and mining enterprises, school and public institution have brought into use photoelectric direct-reading water meter.This water meter structure comprises impeller metering section and counter portion, counter portion is the character wheel registration to be converted into photosignal through the internet or GPRS realization remote meter reading and control, the impeller metering section comprises impeller box, impeller, gearcase and the gear that is installed in the gearcase, impeller is installed in the cavity of impeller box by impeller shaft, the bottom of impeller box and top offer respectively water inlet and water delivering orifice, gearcase is installed on the top of impeller box, the part that the upper end of impeller shaft penetrates in the gearcase and impeller shaft penetrates gearcase is provided with the gear that is meshed with the gear installed in the gearcase, the gear of installing in the gearcase is connected with counter portion by drive disk assembly again, current are entered in the impeller box cavity by the water inlet of impeller box, promote the wheel rotation in the impeller box cavity, the water delivering orifice by the impeller box top flows out at last.During wheel rotation in the cavity, rotate by the digit wheel that the gear in the gearcase and drive disk assembly drive dial plate by the gear on the impeller shaft again, counter portion is that photosignal passes to control center through transport sector with signal with the character wheel registration by coder transitions.
The impeller box of existing water meter is typically provided with six inlet openings and six apopores, owing to the reason of water inlet hole shape and centre distance to making fluid little to the impulsive force of impeller, the low discharge of water meter can't measure, and causes low discharge reading out of true.Existing water meter Q3/Q1(flow/minimum flow commonly used) ratio can only reach 80 times.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of ratio that can measure low discharge, Q3/Q1 can reach the impeller box of the wide-range photoelectric direct-reading water meter more than 160 times.
The purpose of this utility model is achieved through the following technical solutions: a kind of impeller box of wide-range photoelectric direct-reading water meter, it comprises body, the middle part of body is provided with cavity, the bottom of body and top offer respectively water inlet and water delivering orifice, the bottom of body is provided with eight water inlets, and the top of body is provided with four water delivering orifices; The bottom surface of the cavity of body is provided with six～eight deceleration stems, and the deceleration stem is for radially extending, be arranged at raised line on the bottom surface along body.
Described deceleration stem circumferentially evenly distributes along body, and the height of deceleration stem is 3～4mm.
Described water inlet circumferentially evenly distributes along body, and the horizontal section of water inlet is rectangle, and the distance of water inlet distance body center line in parallel is 18～19mm.
Described water delivering orifice circumferentially evenly distributes along body, and the horizontal section of water delivering orifice is rectangle, and the distance of water delivering orifice distance body center line in parallel is 15～16mm.
The utlity model has following advantage: water inlet of the present utility model is set to rectangle, and the distance of the impeller box center line that the 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 measuring more low discharge; The bottom surface of impeller box cavity is provided with the deceleration stem, and the deceleration stem is adjusted wheel speed when impeller is rotated by water impact, realizes the accurate measurement of each flow point, thereby has improved the precision of water meter measurement, and the ratio of Q3/Q1 can reach more than 160; Fluid was more unobstructed when thereby the sectional area that four uniform designs of water delivering orifice have increased water delivering orifice had guaranteed large flow.
Description of drawings
Fig. 1 is structural representation of the present utility model
Fig. 2 is that Fig. 1 is along the cut-open view in B-B cross section
Fig. 3 is plan structure synoptic diagram of the present utility model
Among the figure, 1-body, 2-cavity, 3-water inlet, 4-water delivering orifice, 5-bottom surface, 6-deceleration stem, the distance of the body center line that d1-water inlet distance is in parallel, the distance of the body center line that d2-water delivering orifice distance is in parallel.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, protection domain of the present utility model is not limited to the following stated:
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of impeller box of wide-range photoelectric direct-reading water meter, it comprises body 1, the middle part of body 1 is provided with cavity 2, the bottom of body 1 and top offer respectively water inlet 3 and water delivering orifice 4, the bottom of body 1 is provided with eight water inlets 3, and the top of body 1 is provided with four water delivering orifices 4; The bottom surface 5 of the cavity 2 of body 1 is provided with six～eight deceleration stems 6, deceleration stem 6 for along body 1 radially extend, be arranged at raised line on the bottom surface 5, the best arranges eight deceleration stems 6 on the bottom surface 5 of cavity 2.
Such as Fig. 2, shown in Figure 3, described deceleration stem 6 circumferentially evenly distributes along body 1, and the height of deceleration stem 6 is 3～4mm, and its optimum height is 3.2mm or 3.5mm.
As shown in Figure 2, described water inlet 3 circumferentially evenly distributes along body 1, the horizontal section of water inlet 3 is rectangle, and the distance of water inlet 3 distance body 1 center line in parallel is 18～19mm, body 1 center line that water inlet 3 distances are in parallel be 18.5mm apart from d1 the best.
As shown in Figure 3, described water delivering orifice 4 circumferentially evenly distributes along body 1, the horizontal section of water delivering orifice 4 is rectangle, and the distance of water delivering orifice 4 distance body 1 center line in parallel is 15～16mm, body 1 center line that water delivering orifice 4 distances are in parallel be 15.1mm apart from d2.
Water meter is when work, fluid is rule by water inlet 3 after rectangular water inlet 3 shapings water column impacts the impeller in the impeller box, thereby rotate the realization metering by the gear driven counter in the gearcase in the time of vane rotary, simultaneously, the rotating speed of the 6 pairs of impellers of deceleration stem on the bottom surface 5 of cavity 2 is adjusted, thereby realizes the accurate measurement of each flow point.
