PURPOSE: A bellows valve equipped with blocking part is provided to prevent a disc and hole junction, which is produced by collision of fluid, by using bellows. CONSTITUTION: A bellows valve equipped with blocking part comprises a valve body(100), a disc(200), a principal axis(300), a drive tool, a bellows(500), and a blocking part(600). The valve body comprises a fluid inlet, a fluid outlet, a blocking wall, and a hole. The disc ascends and descends in the inlet hole and opens and closes the hole. The principal axis is combined on the top of the disc. The drive tool elevates the principal axis. The bellows protects the outer surface of the principal axis in the inlet hole. The blocking part prevents the contact of bellows with fluid.
