Title:
VALVE BODY CONTROLLING FLUID FLOW DIRECTION AT ROTATIONAL ANGLE POSITION
Document Type and Number:
Japanese Patent JP2016211733
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a valve body controlling bidirectional fluid flows with a simple structure.SOLUTION: Both sides inside an internal passage 20 communicate with a first connection part 26 and a second connection part 28, and inside the internal passage, formed is a check ball fixation part 24 to which a check ball 18 is fixed. The internal passage 20 is inclined by rotation of a rotational shaft 16, and thereby the check ball 18 is closely contacted, by sedimentation force or buoyancy, to the check ball fixation part 24 positioned downward, thereby to restrict flow of fluid from the internal passage 20 to any of the first connection part 26 and the second connection part 28.SELECTED DRAWING: Figure 1
