摘要

A check valve has a valve body (2), valve seats, and a hinge pin which extends across the body.

A pair of semi-circular plates (14,16), with hinge lugs (56,58), are mounted on the hinge pin, by means of the hinge lugs, so as to allow rotation of the plates from closed positions, in which valve faces engage their respective valve seats in the open position. In the open position, the valve faces are separated from their respective valve seats.

USE/ADVANTAGE -The valve plates of this check valve are very much cheaper to produce than plates in known existing designs, which are usually cast and then machined. The plates of the present design are also lighter in comparision, and should therefore improve the efficiency of the valve by reducing pressure losses and closing time.
