Abstract

PURPOSE: To constitute a whole pressure cylinder simply without including a hydraulic equipment and its controller by redesigning the structure of the pressure cylinder which drives an emergency unit.
CONSTITUTION: A projection end from a valve case 5 of a valve rod 4 provided with a valve body 3 is connected with an arm 6 and a pressure cylinder 8 is jointed with the arm 6 via a link 8 to shut off the valve body 3 at an emergency. A mechanism 9 operates the cylinder 8 on a detection of abnormal increase in velocity of flow is connected with said cylinder 8. The emergency shut-off valve 2 provided in a transportation pipe 1 is so constituted. The cylinder 8 contains a bomb 10 on the lower side of the container 8a and the bomb is airtightly filled with compressive gas. When the sensor 14 of said mechanism 9 feels an abnormal increase in velocity of flow, a connecting element 16a becomes out, that results in a turn of a hammer 19 in the direction an arrow to give an impact on a needle A. Said bomb 10 is therefore opened to close the valve body 3.
