Large diameter meter valve integrated water meter

Abstract

The present invention relates to the field of water meter devices, in particular to a water meter with integrated large-diameter meter and valve, which includes a water meter housing, a character wheel box is installed in the water meter housing, an impeller box is installed under the character wheel box, and the impeller The box is inserted into the impeller bracket, and the impeller bracket is inserted into the diaphragm switch. The water inlet is provided with an adjustment mechanism, and the adjustment mechanism includes an adjustment plate, a metering plate and a fixing plate, wherein two adjacent water flow baffles are provided There are support holes, and the fixing plate is provided on the impeller box corresponding to the support hole, and the fixing plate is respectively provided with a mounting hole and a fixing hole; one side of the metering plate is fixed with an adjustment shaft. The front end of the adjustment shaft is inserted into the support hole through the installation hole and the adjustment plate in turn. The rotation of the metering plate drives the adjustment plate to rotate, so that the water flow can be finely adjusted and the accuracy of the water meter can be controlled. After the adjustment is completed, the bolts are tightened, and the adjustment plate and the metering plate are tightly fixed.

Description

technical field [0001] The invention relates to the field of water meter devices, in particular to a large-diameter meter-valve integrated water meter. Background technique [0002] At present, most of the residential water meters use water to drive the impeller to rotate to measure the cumulative amount of residential water, that is, the rotor water meter. Water meters can be divided into volumetric type and rotor type. The volumetric type is equivalent measurement, while the rotor type is based on the speed of the water flow and the speed of the impeller to achieve indirect measurement. The rotor type water meter can be divided into dry type and wet type. The rotor type wet type water meter is connected to the water supply pipe. The casing and the gland on the upper part form a volume body. The connection between the fluid inlet and outlet is the casing, and the upper part is the counter. The lower part is the impeller box. There are impeller and bottom shaft in the impel...

AI Technical Summary

Problems solved by technology

The disadvantage of this structure is that the water inlet and outlet holes of the water meter are set on the side of the impeller box, and the baffle moves up and down at the water inlet. The gap between the baffle plate and the impeller box will be punched out, resulting in inaccurate measurement
