Autoregulation valve for controlling the gas flow in high pressure systems

摘要

A valve autoregulation (16) for controlling a gas flow in high pressure systems, comprising laválvula (16): a valve body (24) having a gas inlet (44) and a gas outlet (46); a slidable plug (26) housed in the valve body (24), the slidable plug (26) having a primerextremo and a second end, and being slidable between a first position and a second position, a primary flowpath (64) connecting the gas inlet (44) and the gas outlet (46), increasing the flow pasoprimario (64) with the linear movement of the sliding plug (26); a valve seat tapered (52) to close the primary flow passage (64) when the tapóndeslizable (26) is in the first position and to open the primary flow passage (64) when the tapóndeslizable moves to the second position wherein the sliding cap (26) further comprises uncuerpo tapered (58) to engage the valve seat tapered (52) when the sliding plug (26) is in the first position; a first chamber (40) located adjacent the first end of the slidable plug (26); a second chamber (42) located adjacent the second end of the slidable plug (26); a first spring (28) for applying a first spring force to the slidable spool (26) toward segundaposición; a second spring (30) for applying a second spring force to the slidable spool (26) toward primeraposición; a first passage (72) connecting the gas inlet (44) and the first chamber (40); a second passage (74) connecting the gas inlet (44) and the second chamber (42); and a valve actuator (32) to actuate the valve (16), opening the first step (72) to make the tapóndeslizable (26) approaches the second position
