    摘要： An auto-drain unit for a compressed gas supply system, comprising: a first, main chamber (24) including a liquid collection reservoir (27); a second, reference chamber (25); a discharge valve (35) actuatable to discharge collected liquid from the liquid collection reservoir (27); a trigger mechanism (37) for actuating the discharge valve (35); a diaphragm (23) at least in part defining the liquid collection reservoir (27) and the reference chamber (25), the diaphragm (23) being configured to be movable under the weight of liquid collected in the liquid collection reservoir (27) and operate trigger mechanism (37) when the weight of collected liquid exceeds a predetermined threshold; and a fluid conduit (41) fluidly connecting the reference chamber (25) to a location in the main chamber (24) above the maximum possible liquid level therein.

    摘要： A pipeline (12) for the transportation of a process fluid comprises an autonomous shut-off valve system comprises a shut-off valve (1) including a fluid powered valve actuator (2) moveable between a closed and an open position by means of pressure generated by the process fluid, a pressure tapping (3) in the pipeline upstream of the shut-off valve, a fluid connection to the pressure tapping arranged to deliver process fluid to power opening of the said shut-off valve, at least one pressure sensor (16) arranged in a hydraulic line extending from the pressure tapping, at least one control valve (8A, 8B, 8C) operable to permit or prevent flow of pressurised fluid to the shut-off valve actuator; and a controller (15) arranged to open and close the control valve. The control valve is commanded to open and close when pressure thresholds are reached, the pressure thresholds being detected by the pressure sensor and the control valve being commanded to close by the controller.

    摘要： Vorrichtung zur Verhinderung des Mitmessens gasförmiger Beimengungen bei der Abgabe von Flüssigkeiten aus einem ersten in einen zweiten Behälter über eine Förderleitung, in der ein Mengenzähler und eine Absperrarmatur angeordnet sind, dadurch gekennzeichnet, daß eine Druckmeßvorrichtung den Druck in der Förderleitung mißt, die Absperrarmatur in ihrem wirksamen Querschnitt regelbar ist und eine Regelvorrichtung eine variable Drosselung der Absperrarmatur bewirkt derart, daß bei einem ersten positiven Druckwert die Drosselung einsetzt und bei einem zweiten niedrigeren positiven Druckwert die Absperrarmatur geschlossen wird.
