Description
Technical Field
The utility model belongs to the technical field of the water gauge flow test technique and specifically relates to indicate a novel water gauge impeller box.
Background
The metering mechanism of the water meter on the market at present mainly comprises an impeller box, an impeller shaft and a regulating valve, wherein the principle of flow regulation is as follows: the water meter core wear-resistant performance is greatly reduced, meanwhile, the water outlet adjusting hole on the side wall of the adjusting valve is a large rectangular hole, because the rectangular area is too large, the size of the opening is not easy to control in the process of rotating and adjusting through a tool, and the sensitivity of adjusting the water meter core is improved.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a novel water gauge impeller box, the design is simple reasonable, not only promotes the stability of water gauge flow performance and the stand wear and tear performance of water gauge, can effectively reduce the sensitivity that the water gauge core was adjusted moreover, promotes the qualification rate of once adjusting the flow check-up to promote production efficiency. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a novel water gauge impeller box, includes impeller box body and governing valve, the governing valve is the closed siphonozooid of one end, be equipped with the recess of the instrument rotation regulation of being convenient for on the closed one end terminal surface of governing valve, the symmetry formula is equipped with a plurality of mounting holes that are used for installing the governing valve on the impeller box body lateral wall, be equipped with the play water regulation hole of a plurality of cascaded play water regulation holes or even interval formula on the governing valve lateral wall.
Further, the groove is a straight groove or a cross groove.
Further, the number of the mounting holes is 2.
(III) advantageous effects
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a symmetrical formula sets up the governing valve, and then promotes the stability of water gauge flow performance and the stand wear and tear performance of water gauge, through improving to adjusting the apopore structure, can effectively reduce the sensitivity that the water gauge core was adjusted, promotes the qualification rate of regulation flow check-up once to promote production efficiency.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1, a novel water meter impeller box comprises an impeller box body 1 and an adjusting valve 2, wherein the adjusting valve 2 is a tubular body with a closed end, a water inlet 23 is arranged at the bottom of the adjusting valve 2, a groove 21 convenient for tool rotation adjustment is arranged on the closed end face of the adjusting valve 2, the groove 21 is a straight groove or a cross groove, a plurality of mounting holes 11 used for mounting the adjusting valve 2 are symmetrically arranged on the side wall of the impeller box body 1, the number of the mounting holes is 2 for manufacturing, and a plurality of stepped water outlet adjusting holes 22 or water outlet adjusting holes 22 with even interval are arranged on the side wall of the adjusting valve 2.
Referring to the first embodiment of fig. 2, the water outlet adjusting holes 22 may be designed as small vertical rectangular holes with stepped intervals, and the smallest rectangular hole is close to the inner side of the rotating portion, so that the size of the water outlet adjusting holes 22 is gradually reduced during rotation.
Referring to fig. 3, the second embodiment shows that the water outlet adjusting hole 22 may be designed to be triangular, and the angle of the triangle is close to the inner side of the rotating portion, so as to gradually reduce the size of the water outlet adjusting hole during rotation.
Referring to the third embodiment shown in fig. 4 and the fourth embodiment shown in fig. 5, the water outlet adjusting holes 22 may be square or circular holes with uniform spacing, so as to gradually reduce the size of the water outlet adjusting holes during rotation.
The utility model discloses a symmetrical formula sets up the governing valve, and then the stability of promotion water gauge flow performance and the stand wear and tear performance of water gauge through improving to adjusting the apopore structure, can effectively reduce the sensitivity that the water gauge core was adjusted, promotes the qualification rate of once adjusting the flow check-up to promote production efficiency.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
