Abstract
The utility model relates to an impeller case driven by liquid, which comprises an impeller case body which respectively has a plurality of tangential water outlets communicated with meter body water outlet holes and a plurality of tangential water inlets communicated with meter body inlet holes, and an impeller is placed in the impeller case body. The utility model is characterized in that the bias-cutting directions of the tangential water inlets and the tangential water outlets are the same. The utility model has the advantages that when the impeller case is used, no matter the meter body is installed in a forward direction or a reverse direction, an indicating needle of a water meter always rotates along a correct direction to effectively prevent water stealing.
Description
The utility model relates to a kind of gauging table annex of tracer liquid flow, particularly a kind of liquid driven impeller box that is applied in the water meter.
Be widely used in its liquid driven impeller box of metering water meter on the water supply pipe at present and mainly comprise the impeller box body of a plurality of tangential water inlets of a plurality of tangential water delivering orifice that has connection table body apopore up and down respectively and connection table body inlet opening, drive the impeller that indicator of water gauge rotates and place in this box body.The maximum deficiency of its existence is that the direction of cutting sth. askew of a plurality of tangential water inlets and a plurality of tangential water delivering orifices is opposite.Like this when the user oppositely installs water meter, the inlet opening that is about to show body and impeller box body top with a plurality of tangential water delivering orifice be connected, apopore and the impeller box body bottom of table body with a plurality of tangential water inlets be connected, make the indicator of water gauge backward rotation, giving surreptitiously, the water person provides convenience.
At the deficiency of above-mentioned prior art existence, but the purpose of this utility model provides a kind of liquid driven impeller box of water-stealing-preventing.
The purpose of this utility model is achieved in that it comprises that impeller box body, the impeller of a plurality of tangential water inlets of a plurality of tangential water delivering orifice that has connection table body apopore respectively and connection table body inlet opening place in this box body, and it is characterized in that: the direction of cutting sth. askew of a plurality of tangential water inlets and a plurality of tangential water delivering orifices is identical.
The utility model has the advantages that using this impeller box no matter to show body is that forward is installed or oppositely installed, the pointer of water meter always rotates along a correct direction, can effectively prevent surreptitiously water.
Below in conjunction with accompanying drawing the utility model is explained.
Fig. 1 is the utility model structural representation.
Fig. 2 be among Fig. 1 K to view.
Fig. 3 is an A-A view among Fig. 1.
With reference to the accompanying drawings, the utility model mainly comprises impeller box body 3 and places the interior impeller 2 of this box body, wherein impeller box body 3 upper side be equipped with can connection table body apopore a plurality of tangential water delivering orifice 3-1, the lower side of impeller box body 3 have can connection table body inlet opening a plurality of tangential water inlet 3-2, the direction of cutting sth. askew of a plurality of tangential water inlet 3-2 and a plurality of tangential water delivering orifice 3-1 is consistent, no matter water enters from tangential water inlet, still enter from tangential water delivering orifice, impeller 2 sense of rotation unanimities, thereby effectively prevent surreptitiously water, sequence number 1 among the figure is the impeller lid, and impeller shaft passes this lid and is convenient to drive the driven wheel of indicator of water gauge and links to each other.
