Abstract

PURPOSE:To enhance rigidity of a valve body and reduce fluid friction loss with a simple construction by providing a rib perpendicular to a main plate in the central portion of a sub-plate mounted angularly on the main plate. CONSTITUTION:A sub-plate 2 is slantwise mounted on a main plate 1. The main plate 1 and sub-plate 2 are interconnected with a rib 3 in the central portion of the main plate 1 and the other ends of the main plate 1 and sub-plate 2 are connected with each other. Thus, since a valve body is constructed to have a truss roof to endure large stress, the number of the ribs 3 can be reduced. Hence, since area contacting fluid is reduced, the fluid friction loss can be reduced.
