WATER PRESSURE CONTROL TYPE WATER METER DEVICE

摘要

PURPOSE: A water pressure control type meter device is provided to allow for uniform supply of water and prevent no-load operation of the water meter by maintaining water pressure constant. CONSTITUTION: A water meter device comprises a case(1); a water meter(10) embedded in an outlet port of the case; and a pressure reduction valve(30) embedded in an inlet port of the case, and which controls the pressure of the water flowing toward the water meter constant. The water meter includes a water meter casing arranged at the outlet port side of the case and communicated to the inlet port and the outlet port of the case; an upper cover(14) screw-coupled to the top of the water meter casing; an upper case(16) mounted in the inner upper portion of the water meter casing; a lower case(18) mounted in the inner lower portion of the water meter casing, and which has a plurality of fluid outlets(13) and inlets and a support shaft arranged at the center of the inner bottom surface of the lower case; an impeller(20) having a driving gear mounted on the upper portion of the impeller, and which is supported by the support shaft in such a manner that the impeller is rotatable; and an integrating indicator(24) for integrating flow of fluid through a plurality of metering gears engaged with the driving gear of the impeller.
