VALVE AND CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP2015140810
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restrict a valve from being rotated unintentionally from its opened position to its closed position and being closed.SOLUTION: A stop valve comprises a cylindrical member 11, a flow passage hole 13, a rotation indicating member and a bolt. The cylindrical member 11 is formed into a cylindrical shape that can be rotated around a cylindrical shaft and the cylindrical member is inserted into a flow passage pipe 3 and fixed in such a manner as one in which a cylindrical shaft direction and a flow passage direction of the flow passage pipe 3 are crossed at a right angle. The rotation indicating member and the bolt stop a rotation of the cylindrical member 11 in a direction RD1 where the flow passage of the flow passage pipe 3 head from a closing position toward an opened position for releasing the flow passage. At the opened position, a part of a circumferential surface part W of the cylindrical member 11 appears in the flow passage of the flow passage pipe 13 so as to cause the cylindrical member 11 to be turned in a direction RD due to fluid impingement.
