Plates for dual plate check valves |
摘要 |
A metal plate 20 for a dual plate wafer check valve. A central portion 36 of the D shaped plate 20 is reinforced such as by means of a raised area 36 on either or both sides of the plate to resist deformation when subjected to reverse pressure in the valve closed position, while the D shaped edge portion 32 of the plate is made sufficiently flexible to maintain or improve sealing engagement with a valve seat even when the valve seat is distorted by the effect of reverse pressure in the valve closed position. |
