Abstract
PURPOSE:To completely prevent the stagnation of a fluid flowing inside by forming a flow passage closing part and diameter-spreading flow passage parts on both sides of the closing part with a soft elastic material and opening/closing the flow passage with a slit formed on the flow passage closing part. CONSTITUTION:A flow passage closing part 12 is formed in the center and diameter spreading flow passage parts 13 in which the diameter of a flow passages is smoothly spread are formed on both sides of the closing part 12, of a valve body 11 made of a soft elastic material such as silicone rubber, etc. A slit is provided on the flow passage closing part 12. And, a pair of opening/closing plungers 21, 22 are provided on the outside of the flow passage closing part 12. When a valve closing force is given from up and down by means of the plungers 21, 22, the slit type passage 15 is securely closed. As the plungers 21, 22 are moved in mutually separating directions, the slit 15 is opened due to fluid pressure allowing a fluid to flow. Thereby, the sectional area of the fluid passage can be smoothly changed without fear of causing stagnation in the flow passage.
