Water-saving water supply and drainage system for building

Abstract

The invention relates to a water-saving water supply and drainage system for a building, belonging to the technical field of building construction engineering. The water-saving water supply and drainage system comprises a main drainage pipe, a floor drain and a connecting pipe, wherein the floor drain comprises a floor drain body and a cover plate; the floor drain body is provided with a mountinggroove in a vertical direction; the cover plate is provided with a filter hole and is slidably arranged in the mounting groove; the opening of the mounting groove is provided with a limiting member; aclearing rod is arranged, opposite to the filter hole, in the mounting groove; an elastic return member for driving the cover plate to abut against the limiting member is arranged in the mounting groove. A user only needs to press down the cover plate by hand, and the cover plate moves downward along the mounting groove and compresses the elastic return member; during the downward movement of thecover plate, the clearing rod is gradually inserted into the filter hole and pokes out garbage which is blocked in the filter hole, the clearing is completed, then the pressing of the cover plate isreleased, and the cover plate is automatically reset to the state of abutting against the limiting member under the action of the elastic return member. The floor drain is convenient to clean, so thatthe floor drain drains water smoothly.

Description

technical field [0001] The invention relates to the technical field of house construction engineering, in particular to a water-saving building water supply and drainage system. Background technique [0002] Building water supply and drainage design is an important part of architectural design. Building water supply and drainage mainly involves building water supply and sewage treatment. Whether the design is reasonable or not has a very important impact on subsequent building construction and the normal use of residents. [0003] Floor drain is a key point in architectural design. Floor drains are designed and installed on the kitchen and bathroom floors of the living room of the building to discharge sewage and prevent odor from rising. Existing floor drains generally consist of a floor drain main body, a retaining screen, a sealing bowl and a floor drain cover; the lower port of the floor drain and floor drain main body is equipped with a short pipe, which can be connecte...

AI Technical Summary

Problems solved by technology

[0004] The distance between the plane where the sieve is located in the main body of the floor drain and the plane of the floor drain cover is very small, so as long as a little dirt accumulates on the sieve, it will be easily blocked, resulting in poor drainage. Therefore, the sieve needs to be cleaned frequently, but the space above the sieve The cavity is narrow, it is difficult to reach in and take out the sieve, and it is very inconvenient to clean
