# Durability testing apparatus for water drainage flap, and testing method using the durability testing apparatus for water drainage flap

## Abstract

A durability testing apparatus for a water drainage flap to test the durability of the water drainage flap. The water drainage flap comprises a flap column, a water drainage plate arranged inside the flap column and a water drainage rotation shaft connected with the water drainage plate. The durability testing apparatus for the water drainage flap comprises: a vibration table for providing vertical reciprocal vibration and a water inlet flange disc fixed on the vibration table for supplying water to the water drainage flap, wherein the water inlet flange disc comprises a base fixed to the vibration table and a water inlet column arranged on the base and facing the water drainage flap, a water inlet is provided in the water inlet column, the water inlet column and the flap column enclose a water inlet chamber, and the water inlet communicates with the water inlet chamber.
