FLOW PATH CONVERSION VALVE

摘要

The present invention pertains to a flow path conversion valve, which comprises: a tubular body (3) having at least one or more inlets (13) for supplying fluid to the inside, two or more outlets (15, 16) for the selective crossover discharge of the internal fluid, drain holes (17, 18) respectively formed for draining the fluid which is not discharged via the outlets (15, 16) but remains in the inside and securing sections (19) respectively protruded on the inner peripheral surface at each said inlet (13), said outlets (15, 16) and said drain holes (17, 18); an operation rod (5) concentrically mounted in the tubular body (3), having a plurality of holding sections (21-1, 21-2, 21-3, 21-4) protruded on the outer peripheral surface to be spaced apart from each other, and connected to an operation means at one side end, which is exposed to the outside in a fluid-sealing state, so that the operation rod (5) reciprocates back and forth by the operation means in the tubular body (3) in the axial direction; and a plurality of movable valve bodies (7-1, 7-2, 7-3, 7-4) movably mounted on the outer peripheral surface of the operation rod (5) and disposed between each of the holding sections 21-1, 21-2, 21-3, 21-4) so as to individually correspond to each of the securing sections (19).
