Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of impeller seat structures, in particular to a kind of impeller seat structure of zonal regulation of shunt type. BACKGROUND

[0002] Impeller is usually arranged in impeller seat, water flow impacts impeller after passing through the bottom of impeller seat, and drives impeller to rotate, and impeller is connected to water meter flow meter by impeller shaft, so as to achieve the effect of calculating flow.

[0003] However, the existing impeller seat structure is all without shunt regulation effect, whether in the place where water flow is large or small, all water will impact impeller, which will lead to inaccurate measurement in the place where water flow is small, and impeller may be damaged by impact in the place where water flow is large, resulting in unable to measure. UTILITY MODEL CONTENTS

[0004] The utility model aims at overcoming the defects of the prior art and provides an impeller seat structure of zonal regulation of shunt type.

[0005] The utility model can achieve the purpose by the following technical scheme.

[0006] An impeller seat structure of zonal regulation of shunt type, wherein the impeller seat structure comprises an impeller seat body; the impeller seat body is provided with an outer shunt groove and an inner impeller groove; a plurality of shunt baffles are uniformly arranged in the outer shunt groove; and an impeller assembly is arranged in the inner impeller groove.

[0007] Further, the impeller assembly comprises a magnet steel support, an impeller and a bushing assembly; the bushing assembly comprises an upper bushing structure assembled in the magnet steel support and a lower bushing structure assembled at the central position of the bottom of the impeller; and the magnet steel support and the impeller are fixed by interference fit through a pin shaft.

[0008] Further, the impeller comprises an impeller shaft and a plurality of impeller blades; each of the impeller blades is in spiral shape and is uniformly and vertically distributed at 360 degrees with the impeller shaft as the central axis.

[0009] Further, the magnet steel support is fixed at the top of the impeller; the top of the impeller is provided with a fixing hole; and the pin shaft is fixed in the fixing hole by injection molding process.

[0010] Further, the impeller seat structure is made of plastic material.

[0011] Compared with the prior art, the utility model has the following advantages.

[0012] (1) This utility model divides the impeller seat body into two areas: an outer diversion groove and an inner impeller groove. A diversion baffle is set in the outer diversion groove, which can realize the zonal adjustment of water flow and diversion. This prevents all the water from impacting the impeller assembly, thus sharing the impact force with the impeller assembly, preventing damage to the impeller assembly, and extending its service life.

[0013] (2) The number of diversion baffles of this utility model can be designed according to needs. When used in places with large water flow, a few diversion baffles can be reduced so that more water flows out from the outer diversion groove and the impeller pressure is reduced. When used in places with small water flow, a few more diversion baffles can be added so that the water is blocked and more flows through the inner impeller groove, thereby measuring the water flow. The application range is wider and the measurement is more accurate. Attached Figure Description
