<p>A foreign object in a discharge path defined and formed in a valve case i s 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 pa th (4), the valve chamber (2) allowing gas (A) and liquid (W) to flow into i t through an inlet pipe (1), the discharge path (4) communicating with a dis charge 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 op ening (6a) by movement of a float member (7) floating on the liquid (W) havi ng 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 disch arge path (4), a foreign object in the discharge path (4) and provided so th at 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 co nstructed so that it penetrates through the valve opening (6a) when it is mo ved forward in the discharge path (4) by being screwed into a screw thread s ection (10a) formed in the valve case (5).</p> |
