Abstract
The utility model provides a kind of water meter impeller box, comprise impeller box body, the periphery of described impeller box body offers multiple inlet opening, this inlet opening is relative to the radial skew of described impeller box body, the upper surface of described impeller box body offers multiple effluent trough, this effluent trough is relative to the radial skew of described impeller box body, and the vergence direction of described inlet opening and effluent trough is contrary.The utility model enough realizes the smooth flow of current in impeller box, is convenient to measure accurately, and the projection, step etc. that are arranged by impeller box body upper end are convenient to location and installation between support simultaneously, and good sealing effect.
Description
Technical field
The utility model relates to water meter technical field, particularly a kind of water meter impeller box.
Background technology
The principle of work of rotary wind type multistream water meter is substantially identical with single channel water meter, it is the distributional effects by impeller box, by the water inlet tangential impact impeller of multi beam current from impeller box, the axial impact force of current to impeller is balanced, decrease the wearing and tearing of impeller supporting part, and reducing water pump composite, fouling to the impact of water meter error from structure, overall performance is apparently higher than single channel water meter.Impeller box has three kinds of effects: one is gone out by water delivering orifice after water comes in impact impeller by inlet opening again; Two is protection wheel rotation; Three is regulate wheel speed.Traditional impeller box, because the design of inlet opening and water delivering orifice is reasonable not, and causes current in impeller box steady not, can affect metering.
Utility model content
The deficiencies in the prior art in view of the above, the purpose of this utility model is to provide a kind of water meter impeller box, makes turnover water flow stationary in impeller box, is convenient to metering.
For achieving the above object and other relevant objects, the utility model provides a kind of water meter impeller box, comprise impeller box body, the periphery of described impeller box body offers multiple inlet opening, this inlet opening is relative to the radial skew of described impeller box body, the upper surface of described impeller box body offers multiple effluent trough, and this effluent trough is relative to the radial skew of described impeller box body, and the vergence direction of described inlet opening and effluent trough is contrary.
Adopt said structure, because inlet opening and effluent trough form contrary vergence direction, and dislocation, impeller box is flowed at water, after promoting wheel rotation, just flow into effluent trough along original direction, there will not be the situation that turbulent flow or blocking cause current to have some setbacks, water flow stationary, makes metering more accurate.
Described inlet opening and effluent trough are rectangle, and described inlet opening is provided with blend stop near one end of impeller box inner body wall, and described blend stop is positioned at bottom, inlet opening.
Described impeller box body upper end outer wall is the up-small and down-big conical surface, and impeller box body upper end inwall is step-like, the impeller box inner body wall above this step is vertically provided with the projection of arc, and described impeller box body upper surface is provided with connecting hole.
Said structure, when fixing with support, by protruding accurate positioning, step-like being convenient to installs sealing.
The width L2 of described inlet opening is 3.5mm-4mm.
The width L1 of described effluent trough is 4.5mm-5mm.
Described inlet opening is 45 °-50 ° relative to the inclination angle beta of normal direction.
Described effluent trough is 45 °-55 ° relative to the tilt angle alpha of normal direction.
As mentioned above, the beneficial effects of the utility model are: this impeller box can realize the smooth flow of current in impeller box, be convenient to measure accurately, the projection, step etc. that are arranged by impeller box body upper end are convenient to location and installation between support simultaneously, and good sealing effect.

Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this instructions can understand other advantages of the present utility model and effect easily.
As shown in Figure 1 to Figure 3, the utility model provides a kind of water meter impeller box, comprise impeller box body 1, the periphery of impeller box body 1 offers multiple inlet opening 11, this inlet opening 11 is relative to the radial skew of impeller box body 1, the upper surface of impeller box body 1 offers multiple effluent trough 12, this effluent trough 12 is relative to the radial skew of impeller box body 1, and the vergence direction of inlet opening 11 and effluent trough 12 is contrary, inlet opening 11 and effluent trough 12 are rectangle, inlet opening 11 is provided with blend stop 13 near one end of impeller box body 1 inwall, blend stop 13 is positioned at bottom, inlet opening 11.
Impeller box body 1 upper end outer wall is the up-small and down-big conical surface, impeller box body 1 upper end inwall is step-like, impeller box body 1 inwall above this step 14 is vertically provided with the projection 15 of arc, upper surface is provided with connecting hole 16 to impeller box body 1, when fixing with support, by protruding 15 accurate positionings, step-like being convenient to installs sealing.
As shown in Figure 4 and Figure 5, the width L2 of inlet opening 11 is 3.5mm-4mm; The width L1 of effluent trough 12 is 4.5mm-5mm, and inlet opening 11 is 45 °-50 ° relative to the inclination angle beta of normal direction, is 48 ° in this example, and effluent trough 12 is 45 °-55 ° relative to the tilt angle alpha of normal direction, gets 50 ° in this example.
Because inlet opening 11 forms contrary vergence direction with effluent trough 12, and dislocation, flow into impeller box at water, after promoting wheel rotation, just flow into effluent trough 12 along original direction, there will not be the situation that turbulent flow or blocking cause current to have some setbacks, water flow stationary, makes metering more accurate.
Above-described embodiment is the principle of illustrative utility model and effect thereof only, but not for limiting the utility model, any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
