PURPOSE: A diaphragm valve is provided to prevent clogging due to thick particles by increasing the diameters of an inlet hole and an outlet hole. CONSTITUTION: A diaphragm valve comprises a casing(10), a central member(20), bellows members(32,34), and an operating unit(100). The central member is installed on the central hole of the casing to be able to reciprocate in a straight line. The bellows members are connected between both sides of the casing and the central member to temporarily store or externally push fluid according to the movement of the central member. The operating unit reciprocates in a straight line and induces the temporary storage or discharge of the fluid.
