    摘要: In a liquid drip prevention valve, an input port is formed in the upper face of a flow passage block, and an output port is formed in the lower face, which opposes the upper face of the flow passage block. In addition, a valve chamber is formed on a side face of the flow passage block, and an air block abuts the side face. Furthermore, a diaphragm valve makes contact with a valve seat when pressure is applied with respect to a back side chamber of the diaphragm valve and separates from the valve seat when the back side chamber is brought to negative pressure, thus forming the liquid drip prevention valve.
