Description

Remote control's leading filter water gauge system of intelligence

Technical Field

The invention relates to the technical field of water meter devices, in particular to a remote control intelligent prefilter water meter system.

Background

The water meter is used for water meters, is a meter for measuring water flow, mostly is used for measuring the accumulated flow of water, generally is divided into a positive displacement water meter and a speed water meter, and originates from England, the development of the water meter has a history of nearly two hundred years, when the specification of the water meter is selected, the size and the flow range of the used flow under the normal condition are firstly estimated, and then the water meter with the specification of which the common flow is closest to the value is selected as the first choice.

The internal structure of the traditional water meter can be divided into a shell, a sleeve and an inner core from outside to inside. The housing is cast pig iron and water passes through the lower annular space of the housing after exiting the water inlet, herein called the "lower annulus". An upper ring chamber is arranged above the annular space and is communicated with a water outlet. The bottom of the sleeve is provided with a filter screen with small holes to filter out sundries in water. The side surface of the sleeve is provided with an upper row of round holes and a lower row of round holes, the positions of the holes are just opposite to the upper ring chamber and the lower ring chamber of the shell, obviously, the lower row is provided with a water inlet hole, and the upper row is provided with a water outlet hole. It is particularly noted that the rows of holes are inclined in the tangential direction of the circle. Note that the upper and lower rows of holes are in opposite directions. The water entering tangentially from the lower discharge hole tends to form a rotating stream of water, which is important to the operation of the meter. The inner core is divided into an upper layer, a middle layer and a lower layer, the upper layer is seen from the glass window, and only the pointer and the dial are arranged. The most critical is the lower layer, here a plastic wheel with many plastic blades on the edge, called impeller.

However, in view of the poor installation environment of some water meters and the damage to the internal structure of the water meter caused by the impurities in the water during long-term use, it is necessary to design a pre-filter installed in front of the water meter for filtering the water.
