Abstract
The utility model discloses an improved water meter impeller box which comprises a cavity which is a cylindrical entirety and an impeller with a plurality of blades, wherein, the bottom and the top of the cavity are provided with a water inlet and a water outlet; the impeller is arranged in the middle of the cavity; the surface of each blade is an inclined spiral surface. Because the surface of each blade is an inclined spiral surface, after entering into the cavity from the water inlet, water flow first touches the inclined blade surface on the bottom right side of each blade, and then rotates and is jetted from a water outlet from the inclined blade surface on the top left side. Even if the water flowing speed is slow or the water pressure is low, after touching the inclined blade surface on the bottom right side of the blade, the water also easily pushes the blade to rotate as pushing a floating plate, so as to improve the measuring precision of the impeller.
Description
Technical field:
The utility model relates to the water meter technical field that each tap water user's water consumption is monitored, and especially relates to the impeller box of water meter.
Background technology:
Tap water is the main source of each city domestic water almost, for tap water user's water consumption is monitored, all water meter need be installed on each user's the running water pipe, so that the water service merchant checks meter and charges.The dial plate of water meter is fixed on the impeller box, see illustrated in figures 1 and 2: existing impeller box has one and totally is cavity 01 cylindraceous and an impeller 02 that is arranged at cavity 01 middle part, blade 02 has a plurality of blades 021, the bottom of cavity 01 and top offer water inlet 011 and water delivering orifice 012 respectively, current are entered in the cavity 01 by water inlet 011, at first be sprayed onto on the blade 021 of impeller 02 vertical again water delivering orifice 012 ejection from cavity 01 top.After current promoted impeller 02 rotation, impeller 02 rotated by the digit wheel of drive disk assemblies drive dial plates in the middle of some again, thereby water consumption is counted.From Fig. 1 and Fig. 2, can see, the blade face of existing its blade 021 of impeller box is perpendicular to impeller 02 central axis, if it is slow or hydraulic pressure is lower to enter water velocity in the cavity 01 from water inlet, current will slip over the blade face of blade 021 and spray from water delivering orifice 012, can't promote blade 021 and impeller 02 rotation, cause water meter measurement inaccurate, the merchant brings economic loss to water service.
The utility model content:
The purpose of this utility model provides a kind of water meter turbine box of improvement with regard to being the weak point that exists at prior art, even also can accurately count under the situation that it is slow in water velocity or hydraulic pressure is lower.
For achieving the above object, the utility model includes an integral body and is cavity cylindraceous and the impeller with a plurality of blades, and wherein, the bottom of cavity and top offer water inlet and water delivering orifice respectively, impeller is arranged at the cavity middle part, the helicoid of the blade face of described blade for tilting.
Described water inlet is inner small and outside big angle.
Water inlet is uniformly distributed in cavity bottom, and tangent with the circumferencial direction of cavity bottom.
The two side of described water inlet is all one section arc-shaped surface.
Described cavity integral body is cylindric, and water delivering orifice is uniformly distributed in the cavity top.
Described water inlet lower end also is provided with the weather board that imports current.
Described water inlet outer also is provided with the water guiding ring that imports current.
After current enter in the cavity from water inlet, at first run into the bottom-right inclination of blade blade face, again by inclination blade face, upper left side rotation ejection freeing port.Even water velocity is slow or hydraulic pressure is low, after water is run into the bottom-right inclination blade face of blade, also will promotes blade rotation easily, thereby improve the counting precision of impeller as promoting kickboard.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is the cut-open view of existing impeller box;
Accompanying drawing 2 is the water inlet structure synoptic diagram of existing impeller box;
Accompanying drawing 3 is the three-dimensional exploded view of the utility model embodiment one;
Accompanying drawing 4 is the cut-open view after the utility model combination;
Accompanying drawing 5 is a water inlet structure synoptic diagram of the present utility model;
Accompanying drawing 6 is the three-dimensional exploded view of the utility model embodiment two.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See that accompanying drawing 3 is to shown in the accompanying drawing 5: the utility model includes an integral body and is cavity 10 cylindraceous and the impeller 20 with a plurality of blades 21, wherein, the bottom of cavity 10 and top offer water inlet 11 and water delivering orifice 12 respectively, impeller 20 is arranged at cavity 10 middle parts, the helicoid of the blade face of blade 21 for tilting.Current are at first run into blade 21 bottom-right inclination blade faces after entering in the cavity 10 from water inlet 11, again by inclination blade face, upper left side rotation ejection water delivering orifice 12.Like this,, after water is run into the bottom-right inclination blade face of blade 21, also will promote blade 21 as promoting kickboard easily and rotate even water velocity is slow or hydraulic pressure is low, thus the counting precision of raising impeller.
The utility model water delivering orifice 12 is uniformly distributed in cavity 10 tops, water inlet 11 is uniformly distributed in cavity 10 bottoms, and it is tangent with the circumferencial direction of cavity 10 bottoms, like this, the inflow that enters cavity 10 from all angles equates, water inlet 11 is inner small and outside big horn-like angle, and its two side is all the curved surface of one section circular arc.Such structure makes discharge hour, and water (flow) direction can not change yet, and directly enters in the cavity, promotes the wheel rotation in the cavity, thereby improves the precision of water meter counting greatly.Current, make also can promote wheel rotation when current are very little, thereby improve the precision that water meter is counted greatly by evenly distribution rotation outflow of water delivering orifice 12 through cavity 10 inwalls.In addition, water inlet 11 lower ends also can install the weather board 30 that is used to import current additional, import in the cavity 10 via water inlet 11 with the current that flow velocity is lower, and stationary flow, eliminate and reflux and turbulent phenomenon, further improve measuring accuracy.
See shown in Figure 6: the utility model also can add the water guiding ring 40 of sleeved shape, and what they were different with the impeller box that installs weather board 30 additional is: install the impeller box of weather board 30 additional, current are entered in the cavity 10 by the side of water inlet 11; And having installed the impeller box of water guiding ring 40 additional, current then are that the bottom by water inlet 11 enters in the cavity 10.
