Toilet drainage system combining siphon and gravity

Abstract

The invention provides a siphon and gravity combined bathroom water discharge system. The siphon and gravity combined bathroom water discharge system comprises domestic sewage pipelines, domestic waste water pipelines, vertical water discharge pipes, vertical ventilating pipes and H pipes. One domestic sewage pipeline and one domestic waste water pipeline are arranged in each house. One end of each domestic sewage pipeline is connected with a toilet / squatting pan in the corresponding house. The other end of each domestic sewage pipeline is connected with the corresponding vertical water discharge pipe directly. The domestic waste water pipelines are connected into a looped network. The looped network is connected with the vertical water discharge pipelines directly. The lower ends of the vertical ventilating pipes are connected with the vertical water discharge pipes, and the upper ends of the vertical ventilating pipes extend out of roofs. The vertical water discharge pipes are connected with the vertical ventilating pipes through the H pipes. The connection positions of the H pipes and the vertical water discharge pipes corresponding to the houses in each floor are higher than the connection positions of the domestic sewage pipelines, the domestic waste water pipelines and the vertical water discharge pipes corresponding to the houses in each floor. By the siphon and gravity combined bathroom water discharge system, the problems of story height needed by bathroom pipeline mounting, deodorization function loss caused by water seal loss and long water discharge time of sanitary appliances are solved.

Description

technical field [0001] The invention relates to the technical field of building drainage, in particular to a toilet drainage system combining siphon and gravity. Background technique [0002] With the rapid development of the construction industry, people have higher and higher requirements for the accommodation environment, especially for bathroom drainage, deodorization, drainage efficiency and other functions. [0003] At present, almost all toilet drainage in China is carried out in the form of gravity drainage system, and the pipe materials are different. However, there are the following concentrated disadvantages in terms of the form of the gravity drainage system: [0004] First, all drainage pipes need to be set with a slope. The slope of all pipes must be along the direction of water flow, and different pipe materials and pipe radii have different slope requirements. This is the requirement for the local settlement height of the same-layer drainage ground and diffe...

Problems solved by technology

[0008] The purpose of the present invention is to provide a bathroom drainage system combining siphon and gravity to solve the problem of the need to reserve enough space for the installation of drainage pipelines in the prior art, the water seal will gradually disappear, the system will lose the anti-odor function, and the drainage time of sanitary ware is relatively long. long question
