Abstract:
Disclosed are a valve capable of preventing a vortex and a core used therefor. The plastic valve comprises: a body made of plastic; a core formed inside the body; and an opening/closing portion. A fluid transfer hole is formed in the inner space of the core such that a fluid moves therethrough. The opening/closing portion contacts one end of the core through a hole of the body, when the valve is closed, thereby blocking the movement of the fluid. At least a part of the portion of the inner surface of the core, which corresponds to the fluid transfer hole, adjacent to the hole of the body, or at least a part of the portion of the core, which contacts the opening/closing portion, has a curved shape.
