Abstract

PURPOSE: To obtain a check valve which is simple in mechanism but operates with sureness, by inserting between a main body, which is made of a plate provided with numerous holes and a holding ring, a flexible and stable plate such as a notched rubber, etc.
CONSTITUTION: A valve body 1 is provided with slitlike holes C, and a valve made of a flexible plate such as rubber sheet which is notched to form a torque-like valve plate, is provided in such a positions as to plug said holes C, and said valve is held by a holding ring 3. For a flow passing upward through the holes C of the valve, the valve 2 is opend as depicted in the sketch to let the fluid flow with less resistance, and for the flow in the opposite direction, the holes C are plugged to stop the back-flowing fluid. With less mechanical rotation and sliding section, this operates with sureness and less trouble.
