Water Meter Shaft
The shell is made of cast iron. After water comes out from the
water inlet, it passes through the lower annular space of the
shell, which is called "lower ring chamber". On the top of the
annular space, there is a "upper ring chamber" connected with the
water outlet. The bottom of the sleeve has a filter screen with
small holes to filter out the impurities in the water.
There are two rows of round holes on the side of the sleeve. The
position of the holes is just opposite to the upper and lower ring
chambers of the shell. The inner core is divided into upper, middle
and lower layers. The upper layer can be seen from the glass
window, with only the pointer and dial.
There is a plastic wheel in the lower layer. There are many plastic
blades on the edge of the wheel, which is called "impeller".
The position of the impeller is just in the rotary flow formed by
the hole in the lower layer of the casing pipe. The water flow
impacts the blade around the wheel, and generates torque to make
the impeller rotate. The bigger the faucet is, the faster the flow
is, and the faster the impeller will turn.
Thus, the water meter shaft needs to be corrosion-resistant, non
rusting, water pressure resistant, relatively high hardness and no
deformation. Tungsten steel water meter shaft has these advantages
and perfectly replaced the steel shaft.
