VALVE AND CONSTRUCTION MACHINE
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.
【課題】バルブが、開位置から閉位置に意図せずに、回動して閉鎖することを抑制する。【解決手段】ストップバルブは、円筒部材１１と流路孔１３と回転指示部材とボルトとを備える。円筒部材１１は、円筒軸を中心に回動可能な円筒形状から成り、円筒軸方向と流路管３の流路方向とが直交するように当該流路管３に挿入して取り付けられる。流路孔１３は、円筒軸方向に直交するように円筒部材１１の周面部を貫通する孔である。回転指示部材及びボルトは、流路管３の流路を閉鎖する閉位置から当該流路を開放する開位置に向かう方向ＲＤ１への円筒部材１１の回動を当該開位置で停止させる。開位置においては、流体の衝突に起因して方向ＲＤに円筒部材１１を回動させるように円筒部材１１の周面部Ｗの一部が前記流路管１３の流路に出現する。【選択図】図７
