When the filter element is to be used for both filtering and connecting purposes, for example, in a lower outlet unit, the first and second end caps 3 and 3 of the filter element are removed to facilitate passage of the second tube 5 of the upper outlet unit through the filter element.
In this embodiment, the lower end of the second pipe 5 of the upper drain opening unit is located 10cm above the filter member of the lower drain opening unit, i.e., the distance between the lower end of the second pipe 5 of the upper drain opening unit and the first filter cover 1 of the lower drain opening unit is 10 cm. This arrangement is provided to make the structure of the combined body of the two drain port units more stable.
In this embodiment, the first filter cover 1 of the upper outlet unit is fitted into the first pipe 4 of the lower outlet unit to be fixed, the second extension plate 7 of the upper outlet unit is supported, and the filter member of the lower outlet unit is connected to the second pipe 5 of the upper outlet unit to be fixed.
In this embodiment, a drain annulus is formed between the second body 5 of the lower drain opening unit and the first body 4 of the upper drain opening unit extending therein. The water draining ring cavity is a water draining channel of the lower water draining outlet unit, and the water filtered by the filtering part of the lower water draining outlet unit flows downwards through the water draining ring cavity and is finally drained out of the water draining outlet unit through the lower end of the second pipe body 5 of the lower water draining outlet unit.
In the roof drainage port assembly of the present embodiment, the drainage pipe of the lower drainage port unit is installed at a water drop port pre-opened in the roof concrete structure layer and embedded in the roof concrete structure, and the first extension plate 6 is tightly connected to the roof concrete structure through a waterproof sealing material (usually, weather-resistant sealant). So set up, ponding in the roofing heat preservation just can be through the drainage outlet unit discharge roofing heat preservation under.
