Abstract

SISTEMA DE VáLVULA PILOTO CARREGADA POR PRESSãO PARA UMA VáLVULA REGULADORA, E, MéTODO PARA OPERAR O MESMO. é provido um sistema e método e válvula piloto carregada por pressão para uma válvula reguladora. O sistema inclui uma válvula reguladora conectando uma linha de entrada a uma linha de saída, um conjunto de válvulas de servo controle, e um conjunto de válvula piloto. Uma linha de suprimento é conectada à válvula de servo controle, e uma linha de pressão de carregamento piloto conecta a válvula de servo controle ao conjunto de válvula piloto. Uma linha de exaustão conecta a válvula de servo controle à linha de saída, evitando deste modo desperdício, poluição, etc., associado à purga de pressão piloto em excesso para a atmosfera.PILOT VALVE SYSTEM PRESSURED FOR A REGULATORY VALVE AND METHOD FOR OPERATING IT. A system and method is provided and a pressure-loaded pilot valve for a regulating valve. The system includes a throttle valve connecting an inlet line to an outlet line, a servo control valve assembly, and a pilot valve assembly. A supply line is connected to the servo control valve, and a pilot loading pressure line connects the servo control valve to the pilot valve assembly. An exhaust line connects the servo control valve to the outlet line, thereby avoiding waste, pollution, etc., associated with excess pilot pressure bleed into the atmosphere.
