To provide a jig for mounting/dismounting a valve body and mounting/dismounting method thereof which can be applied to a mounting/dismounting operation in an oblique direction according to a site.SOLUTION: When dismounting a valve body, the valve body is attached to a support device by aligning a jig base 30 with the drawing direction of the valve body with a spherical bearing 23, and the jig base 30 is moved by a slide plate 25 so as to cancel the movement in the XY direction for the valve body when lowering the support device with a lifting device 10 in order to come out of the tank, whereas, when mounting the valve body, the valve body is attached to the support device, and the jig base 30 is made to align with the drawing direction of the valve body by the spherical bearing 23 and the jig base 30 is moved by the slide plate 25 so as to cancel the movement in the XY direction when raising the support device with the lifting device 10 in order to insert the valve body into the tank.SELECTED DRAWING: Figure 1
【課題】現場に応じて斜め方向への脱着作業に対応できる弁体脱着冶具および弁体脱着方法を提供する。【解決手段】弁体の取り外し時には、球面軸受け23で冶具ベース30を前記弁体の引き抜き方向に一致させて支持装置に弁体を取り付け、昇降装置10で前記支持装置を下げる際に弁体がタンクから抜けるためのXY方向での移動分を打ち消すようにスライドプレート25で前記冶具ベース30を移動させ、弁体を取り付けるときは、支持装置に弁体を取り付けて前記球面軸受け23で前記冶具ベース30を前記弁体の引き抜き方向に一致させ、前記昇降装置10で前記支持装置を上げる際に弁体をタンクに挿入していくためにXY方向での移動分を打ち消すように前記スライドプレート25で前記冶具ベース30を移動させる。【選択図】図1
