LARGE CAPACITY AIR PRESSURE REGULATING SYSTEM WITH ON/OFF VALVE ARRAY

摘要

PURPOSE: A large capacity air pressure regulating system using parallel arrangement of an ON/OFF valve is provided to regulate pressure of large capacity flow with one pressure regulator and to reduce costs of a pressure regulating system. CONSTITUTION: A large capacity air pressure regulating system using parallel arrangement of an ON/OFF valve comprises a upstream pipe(11), a downstream pipe(12), multiple branch pipes(13), opening and closing valves(15), orifices(14), and a pressure regulator(16). Multiple branch pipes connect the upstream pipe and the downstream pipe and are parallelly connected. The opening and closing valves are arranged in each branch pipe to open and close each branch pipe. The orifices are arranged in each branch pipe. The pressure regulator is arranged in one of the branch pipes. Each branch is successively opened according to pressure drop of the upstream pipe.
