Dilatation type drainage converging device for building balcony

Abstract

The invention relates to a building drainage converging device, in particular to a dilatation type drainage converging device for a building balcony. The dilatation type drainage converging device is composed of a vertical pipe drainage section (1), a transverse pipe drainage converging section (2) and a water seal component (3). A guide vane (6) is arranged in a dilatation section of the vertical pipe drainage section (1). A transverse section (9) and a lower inner wall of the transverse pipe drainage converging section (2) are planes or approximate to planes or arc surfaces. The maximum distance of a transverse opening (15) of a converging section top end channel (13) on the transverse pipe drainage converging section (2) which is communicated with the vertical pipe drainage section (1) is larger than that of a vertical opening (16) of the converging section top end channel (13). The distance L between the inner wall edge of the hollow portion of a transverse surface opening (17) on the transverse section (9) of the transverse pipe drainage converging section and the outer wall of the portion, close to the transverse surface opening, of the vertical pipe drainage section ranges from 40 mm to 450 mm. The water seal component (3) can be separated from the transverse surface opening (17). A floor drain cover (23) is arranged on the upper portion (18). By the adoption of the dilatation type drainage converging device for the building balcony, when drainage of the same floor of the building is conducted, under the condition that a floor drain is arranged in the balcony, a floor descent plate and a slight descent plate are not needed.

Description

technical field [0001] The invention relates to a capacity-expanding drainage collector for building balconies, in particular to a drainage collector for toilets, balconies and kitchens. Background technique [0002] At present, when the drainage balcony on the same floor of the building is equipped with floor drains, it is necessary to lower the floor or partially lower the floor. The pipes under the drainage appliances are easy to block and difficult to overhaul, and the water seal of the floor drain is easy to dry up. The odor and harmful gases in the drainage pipes , small insects, etc. are easy to run into the room and affect the living and hygienic environment. Contents of the invention [0003] The purpose of the present invention is to overcome the existing technical defects, to provide a balcony that does not need any lowering floor or micro-lowering board when the floor drain is set in the same floor drainage of the building, the pipeline under the drainage devic...
