摘要： A device for determining the composition of a mixture of fluids that flow along a pipe includes: a radiation source for illuminating the mixture with radiation; a detector for detecting radiation that has been attenuated by the mixture; and a device for monitoring the flow rate of fluid along the pipe and outputting a signal indicative of the flow rate. The device for determining further includes a device for adjusting the intensity of radiation emitting by the radiation source in response to the signal indicative of the flow rate so that the intensity of the radiation source is reduced if the flow rate reduces.

摘要： A method for monitoring a device for regulating the flow of a gas, the device having a flow conduit and a shutter assembly that defines a restriction in the flow conduit. The method includes: causing the transit of gas through the flow conduit; defining a sequence of time intervals (Z1 . . . Zn) of corresponding durations (t1 . . . tn); during each time interval, determining a value of density and a value of velocity of the gas at the restriction; calculating the product of the value of density, of the value of velocity, of the duration of the time interval and of a correction coefficient to obtain a corresponding value of equivalent wear; for each time interval, adding all the values of equivalent wear calculated for the current time interval and for the preceding time intervals to obtain a cumulative value; comparing the cumulative values with a predefined limit value, corresponding to a condition of maximum wear allowable for the shutter assembly, to obtain an indication of the condition of efficiency of the shutter assembly.

摘要： A gas regulator includes: an inlet section fluidically connected to a gas inlet in the regulator, an outlet section fluidically connected to at least one gas outlet from the regulator; a shutter assembly which is movable so as to define at least one opening position in which the gas passes from the inlet section to the outlet section through a restriction, thus generating a pressure drop of the gas, and therefore of a temperature, such as to cause the precipitation/solidification of some substances, in particular the fractions of sulfur and/or its derivative compounds, present in the gas; and an outlet filter with mechanical action which is positioned downstream of the restriction, inside said regulator, to thus retain any solid particles deriving from the precipitation/solidification. The at least one outlet of the gas from the regulator is fluidically connected with a portion downstream of the outlet filter.

摘要： A pressure reduction plant including two or more valve assemblies arranged in parallel and including: pressure reducers for fuel gas from the supply pressure to the delivery pressure; pilot valves to transmit a control pressure to the pressure reducers when the delivery pressure reaches the calibration value of the pilot valves; derivation conduits to transmit the delivery pressure to the pressure reducers, the pilot valves and the pressure reducer devices; command lines to transmit the control pressure from the pilot valves to the pressure reducers. One of the pilot valves is configured with a calibration value greater than the calibration value of all the remaining pilot valves and each command line is configured to communicate with a control line.

摘要： A device for determining the composition of a mixture of fluids by spectral absorption, comprises: a radiation source; a detector for detecting radiation that has been attenuated by the mixture; and a device for separating the radiation into a wavelength band corresponding to an absorption band of one of the fluids, a wavelength band corresponding to an absorption band of another of the fluids, and at least one reference wavelength band substantially adjacent to each of the absorption bands, and especially adjacent to each side of the absorption band or group of absorption bands. The device may be used to determine the composition of mixtures of oil, water and gaseous hydrocarbons in oil wells where there is a very large degree of time varying scattering e.g. Rayleigh and Mie scattering due to turbulence.

摘要： The invention is a gas vent valve (10) for a gas pressure regulator (1), comprising: a tubular body (11) developed between two opposite openings (11a, 11b); a shutter body (12) biased towards a position in which a first opening (11a) of the tubular body (11) is closed and movable from the closed position towards an open position for opening the first opening (11a) due to the effect of a pressure acting from the outside of the tubular body (11) through the first opening (11a); constraining means (13) configured so as to prevent the movement of the shutter body (12) from the closed position towards the open position when the ambient temperature exceeds a predefined value.
