    摘要: A fluid passage is emergently-closed in a short time without causing a water hammer by an extremely simple device and operation. A water hammerless closing device includes an actuator operated valve provided in a fluid passage, an electro-pneumatic conversion device for supplying a 2-step actuator operating pressure Pa to an actuator operated-type valve, a vibration sensor removably secured to the pipe passage on the upstream side of the actuator operated-type valve, and a tuning box receiving a vibration detection signal Pr from the vibration sensor and delivering a control signal Sc to the electro-pneumatic conversion device for controlling the step operating pressure Ps′ of the 2-step actuator operating pressure Pa so that, with the control signal Sc being regulated, the electro-pneumatic conversion device outputs the 2-step actuator operating pressure Pa with the step operating pressure Ps′ capable of bringing the vibration detection signal Pr substantially to zero.

    摘要: A pressure type flow rate control device provides flow rate control for gas at 100-500° C. with an error not more than 1.0% F.S. The pressure type flow rate control device includes a valve body with a fluid passage, a valve portion interposed in the passage, a valve drive unit driving the valve portion to open/close the passage, a restriction mechanism on the downstream side of the valve portion in the passage, a temperature detector detecting gas temperature between the valve portion and restriction mechanism, a pressure detector detecting gas pressure between the valve portion and restriction mechanism, and an arithmetic control device controlling flow rate of gas in the restriction mechanism based on values detected by the temperature detector and the pressure detector, wherein the temperature detector is inserted in an attachment hole of the valve body at a position just above an outlet side fluid passage.
