VALVE FOR PRESSURIZED FLUID CYLINDER AND CORRESPONDING CYLINDER

摘要

The invention relates to a pressurized fluid cylinder, a member (7) for acquiring, storing and processing data, and at least one data-display device (8). The valve (1) comprises a sensor (9) which detects the position of a manual control member (5) for controlling a regulating member (4), and a pressure sensor (10) for measuring the pressure inside the storage space of a fluid cylinder (2). The data-acquisition, -storage and -processing member (7) is designed to: calculate an actual value for the amount of fluid remaining and/or drawn off on the basis of the pressure measurement performed by the pressure sensor (10); calculate a theoretical value for the amount of fluid remaining and/or drawn off on the basis of the regulation performed by the regulating member (4) and measured by the position of the control member (5); compare the actual value based on the measurement of the pressure sensor (10) with the theoretical value imposed by the regulating member (4); and generate a warning signal if the difference between these actual and theoretical values is greater than a specific safety threshold.
