WIPO Patent Application WO/2015/125236
Kind Code:

Abstract:
A vapor valve comprises: a valve main body (70) having therein a flow passage through which vapor flows, the flow passage having a part at which a valve seat (72) is formed; a valve body (73) coming into contact with the valve seat (72) to close the flow passage and moving away from the valve seat (72) to open the flow passage; a valve rod (74) connected to the valve body (73) and extending upward therefrom, the valve rod (74) moving vertically to thereby bring the valve body (73) into contact with the valve seat (72) and move the valve body (73) away from the valve seat (72); a hydraulic drive section (50) disposed, when viewed from above, at a position which is located at a horizontal distance from the valve main body (70) and at which the hydraulic drive section (50) does not overlap the valve main body (70), the hydraulic drive section (50) having a driven rod (52) hydraulically driven forward and backward; a first link section (10) for connecting the driven rod (52) and the valve rod (74) and transmitting the forwardly and backwardly driven movement of the driven rod (52) to the valve rod (74), thereby vertically moving the valve rod (74); a second link section (20) connected to the valve main body (70); and a connection section (30) for connecting the second link section (20) and the first link section (10) and transmitting the horizontal movement of the valve main body (70) to the first link section (10) through the second link section (20).
