A foreign object in a discharge path defined and formed in a valve case is effectively removed. A float type valve device (T) including a valve case (5) having, defined and formed in it, a valve chamber (2) and a discharge path (4), the valve chamber (2) allowing gas (A) and liquid (W) to flow into it through an inlet pipe (1), the discharge path (4) communicating with a discharge pipe (3); a valve opening (6a) for opening the discharge path (4) to the valve chamber (2); open/close means for opening and closing the valve opening (6a) by movement of a float member (7) floating on the liquid (W) having flown into the valve chamber (2); and a foreign object removal member (8) for removing, by moving forward to the valve opening (6a) side in the discharge path (4), a foreign object in the discharge path (4) and provided so that it can advance and retreat in the discharge path (4) by operation of the valve case (5) from the outside. The foreign object removal member (8) is constructed so that it penetrates through the valve opening (6a) when it is moved forward in the discharge path (4) by being screwed into a screw thread section (10a) formed in the valve case (5). |
