Water drainage and toilet flushing system with U-shaped pipe set and sight glass

Abstract

The invention discloses a water drainage and toilet flushing system with a U-shaped pipe set and sight glass, and belongs to the technical field of environment-friendly water treatment. The U-shaped pipe set comprises a three-way four-way joint, a 90-degree elbow, a gas blocking plate, a view lens, a 45-degree elbow and a short pipe; the technical defects that in the prior art, a P-shaped pipeline trap of a cross-layer drainage toilet flushing system is small in water seal volume, difficult in increment and prone to pollution are overcome, and the technical scheme that the U-shaped pipe set is arranged, and the P-shaped pipeline trap is omitted is provided; a longitudinal water seal is horizontally hoisted by the U-shaped pipe set, the volume is doubled, and water storage and excrement storage are carried out fully; the U-shaped pipe set is a primary large water seal assembly and is horizontally connected with an indoor and outdoor drainage main pipe to serve as a protection barrier for drainage and odor isolation of the system, secondary water seal of each indoor sanitary appliance synchronously reduces load and configuration cost, stored excrement of the U-shaped pipe set is flushed away through cross-layer drainage, therefore the common problem that a kitchen and bath drainage system pollutes the interior of a room is eradicated with low manufacturing cost, and the sight glass is arranged to provide accurate operation.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, in particular to a kitchen and bathroom drainage system for houses and other civil buildings. Background technique [0002] A drainage system that replaces reclaimed water by cross-layer utilization of potential energy water (ZL200620001920.6) and a cross-layer drainage and flushing system (ZL201220008603.2) are the patent documents closest to the present invention. For details, see the international retrieval of (ZL201220008603.2) Report: PCT / CN2012 / 086418. [0003] As an existing technology, the cross-layer drainage and flushing system taps the potential functions of the kitchen and bathroom drainage system, adopts the method of cross-layer and horizontal connection of washing water to obtain two kinds of gravity heads of 3 meters and 1 meter, and realizes washing water layer by layer. Household drainage for toilet flushing, clean water flushing toilet reductio...

Problems solved by technology

However, the system pays too much attention to the water-saving effect, and there is no serious and reliable technical solution for the possible pollution caused by the system

[0004] The technical defect of the cross-layer drainage and flushing system is: the P-type pipe trap configured in this system is a commercial pipe fitting with a volume of 1.5 liters. When the system is running, it is used as a primary water seal to take into account the functions of water seal and storage of stool. Not easy to use for a long time

What's more important is that its water seal structure has no longitudinal depth, and it is easy to leak air when water, feces, and objects are mixed, and the air leak will cause odor to rise up, destroying the secondary water seal and polluting the room.
