摘要

PURPOSE: An air pressured water supply apparatus based on a hydraulic air supply type is provided to expand applications of the water supplying apparatus, and to ease maintenance and usage of the same. CONSTITUTION: The air pressured water supplying apparatus based on a hydraulic air supply type includes a manhole(11) at the center of the rear side of a pneumatic water supply tank(10), and the front lower side of the tank(10) is a gas control pipe(12) connected to a gas supply pipe on the top of a buoyance drainage check valve(22). A gas reducing valve(13) and a combination valve(14) are installed at the front center of the tank(10). An electric contact point manometer(19), a gate valve(110), and a gas safety valve(111) are installed at the top of the tank(10), where the gas reducing valve(13) and the gas safety valve(111) are connected through a gas control pipe(12).
