Abstract
The utility model provides an impeller case, which comprises a case body, a cavity arranged in the middle and under the case body for arranging an impeller assembly, a plurality of beveled water inlets and a transverse air outlet arranged on the edge of the cavity, a core clamper arranged in the middle of upper part of the case body for standing the impeller assembly arranged in the cavity. The number of the beveled water inlets is even, and the water inlets are symmetrical each other along the flow line of the outlet. The utility model has the advantages of simple structure and good flow performance.
Description
Technical field: the utility model relates to the impeller box of using on a kind of water meter.
Technical background: existing water meter roughly has two types, a kind of is multithread speed water meter, this water meter is provided with impeller box, impeller box is upper and lower double-layer structure, water inlet below, water delivering orifice is up, flow performance is good, but structure is complicated, and the water meter volume of producing is bigger, and another kind is a single current speed water meter, this water meter does not have impeller box, impeller is directly installed on the watchcase, and this water meter volume is little, simple in structure, but because the water inlet design is unreasonable, cause complex process, impeller assembly discontinuity, lining weares and teares easily, and serviceable life is not long.
Summary of the invention: the purpose of this utility model just provides that a kind of flow performance is good, volume is little, the novel impeller box of long service life.Comprise box body, the middle part, below of box body is provided with the cavity that is used for installing impeller assembly, is provided with several inclined cutout water inlets and a horizontal water delivering orifice on the edge of cavity.In addition the box body upper center be provided with one top, be used to withstand the impeller assembly that is installed in cavity the inside.The number of described inclined cutout water inlet is an even number, and symmetrical each other according to the flow line of water delivering orifice.The utlity model has simple in structure, characteristics such as flow performance is good.
Description of drawings: Fig. 1, the utility model sectional view Fig. 2, the utility model upward view 1 box body 2 top 3 water inlets, 4 water delivering orifices, 5 cavitys
Embodiment: the utility model comprises box body 1, middle part, box body 1 below is provided with a cavity 5 that is used for installing impeller assembly, box body 1 upper center is provided with one and is used to withstand the top 2 of impeller assembly, and the edge of cavity 5 is provided with several inclined cutout water inlets 3 and a horizontal bigbore water delivering orifice 4.The number of described water inlet 3 is an even number, preferably 4 or 6, and water outlet flow line symmetry according to water delivering orifice, because the center of impeller assembly is on the flow line of water delivering orifice, therefore the current of going out from water inlet 3 impact impeller equably, avoided the single load bearing of impeller, the feed water flow of water inlet to water delivering orifice to go out current direction orthogonal.And water inlet and water delivering orifice are in uses a plane, and the volume of impeller box is greatly reduced.
Claims (2)
1. impeller box, comprise box body (1), middle part, box body (1) below is provided with the cavity (5) of laying impeller assembly, the upper center of box body (1) is provided with top (2), it is characterized in that on the edge of cavity (5), being provided with water inlet (3) and water delivering orifice (4), described water inlet (3) is laterally outlet for several inclined cutout inlets, water delivering orifice (4).
