Abstract
182,791. Gomand, G. July 6, 1921, (Convention date]. Tapered plug lift and wedge valves; valves fitted with independently-actuated supplementary valves. - Relates to sluice valves provided with two opposed closure surfaces on which the fluid pressure acts in order to balance the valve. The valve member B, Figs. 2 and 3, is provided with bronze closure surfaces F; working on corresponding bronze seats E. The fluid is diverted by a streamline member R into two streams C, D and the valve member is balanced by the opposed pressures. The valve spindle I is provided with a collar N which prevents axial movement, and the valve is moved vertically by means of a nut M through which the spindle passes. A cover Y may be provided at the bottom to remove sediment. An additional stuffing box may be provided at the bottom through which the spindle projects, so that the pressures on the two ends of the valve may be balanced. In another modification, Fig. 8, the valve member is extended downwards, the extension having a horizontal cross-section B, so that impact of the fluid from the passages C, D is avoided. In the construction shown in Fig. 12, an additional sliding valve R is provided, which, when the main valve is raised, is balanced by the fluid pressures and may be raised to provide a larger area for the fluid flow. The additional valve may be a butterfly valve instead of a sliding valve. In the case of high fluid velocity, the valve may be of larger size and connected to the service pipes by connecting portions of gradually increasing diameter.
