Title:
THREE-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2013/032186
Kind Code:
A1
Abstract:
The present invention relates to a three-way valve which minimizes a pressure variation between the front and rear sides of a plunger when a fluid supply path is switched, thereby preventing noise and vibration caused by water hammering. To this end, the three-way valve comprises: a valve body (210) having an inlet (201), a first outlet (202), and a second outlet (203); a rotor (270) coupled to a driving shaft (291) of a driving part (290) and rotated at a fixed height; and a vertical movement hole (260) through which one end of the shaft (240) coupled to the plunger (250) passes, wherein the vertical movement hole receives the rotational force of the rotor (270) to be vertically reciprocated together with the shaft (240) and the plunger (250). The plunger (250) may be vertically reciprocated between a first valve sheet (211) formed in the first outlet (202) and a second valve sheet (231) horizontally installed between the inlet (201) and the second outlet (203). Here, when the plunger is moved toward the first valve sheet (211), the movement speed of the plunger may be gradually decreased, and when the plunger is moved toward the second valve sheet (231), the movement speed of the plunger may be gradually increased.
