A NON-RETURN VALVE ASSEMBLY OF THE PIVOTING FLAP TYPE, TYPICALLY FOR INSERTION IN FLOOR DRAINS |
摘要 |
A valve assembly (10) is to be used in conjunction with a tubular member having an internal surface surrounding a passage into which the valve assembly is to be sealingly inserted. The valve assembly includes a tubular body (25) having a longitudinal passage and an outer surface to be located adjacent the internal surface. A seal (29) is mounted on the outer surface to engage the internal surface to sealingly connect the tubular body with the tubular member. A movable valve member (33) is movable between an open position providing for the flow of water from an upstream end to a downstream end of the passage of the tubular body and a closed position closing the passage. Resilient means, such as a spring (34) urges the valve member to the closed position. The resilient means is configured to provide for displacement of the valve member toward the open position when pressure beyond a predetermined pressure is applied upon the movable valve member. |
