DISPOSITIVO AUTOMATICO PARA A DRENAGEM DE ESPACOS QUE RECEBEM CONTENTORES DE CARGA OU OUTRAS CARGAS

摘要

The drain comprises a cylindrical outer housing (2) with open ends between which is a bridge-piece (12) containing a through-passage (13). A buoyant closure element (18) closes the through-passage and is positioned on the top of the bridge-piece. A second buoyant closure element (19) for the through-passage is situated on the underside of the bridge-piece. The bridge-piece is connected to a valve cage (11) removably inserted into the outer housing. The bridge-piece divides the valve cage into a top and bottom chambers (14,15). The bridge-piece has a top (16) and bottom(17) valve seating. The outer housing's top end (8) has a fixture flange (9) tightly fixed to the underside of an inner plate facing the storage compartment. The underside (5) of the outer housing is positioned in a beaker-shaped holder fixed to an outer plate of the multi-layered container base (1).
