Fluid e.g. gas or liquid, flow control valve e.g. solenoid valve, for e.g. allowing fluid flow, has blower that detects leakage of fluid downstream movable valve and associated to chamber and bypass, where blower is integrated to valve

摘要

The valve has a blower (4) that detects leakage of a fluid downstream a movable valve (1) and associated to a chamber (C) and a bypass (5). The blower is integrated to the valve. The bypass has a core (51) engaged inside a solenoid (52) and is sensible to a field induced by the solenoid when it is supplied. A detection unit (6) detects a preset position of the core of the bypass and a stopper (54) that are inside the solenoid. A trigger or control signal is sent to the solenoid, for displacing the core inside the solenoid towards the top, when the core attains the preset position.
