Claims

[Scope of utility model registration request]

In a check valve in which a pivot is provided at the top of the valve case to suspend and pivot the valve body, and the valve hole is opened and closed by the rotation of the pivot, the center of the hinge that pivots the valve body is connected to the center of the valve body. A check valve equipped with a double-acting spring, which is located on the rear side, has a fractured part in the hinge, and a spring is inserted into a hinge pin that passes through the fractured part.
