Water closet system with 3 liters of water

Abstract

A water closet system with 3 liters of water comprises a low water seal water closet, a mechanical sealing valve and a drainage pipeline. As the depth of a water seal of a trap of the low water seal water closet can be greatly lower than that of the traditional water closet, the water flushing resistance is greatly reduced, thereby the water flushing amount of the water closet is greatly reduced and the water closet system with only 3 liters of water can reach the national standard requirements and has obvious water saving effect; and as the water closet system is simultaneously provided with the water seal of the trap and a mechanical seal of the mechanical sealing valve, the sealing effect is good, the phenomena of foul gas returning and rising and sewage back flow do not occur. In addition, the water closet system also has the characteristics of simple production, low cost and convenience in installation and use and the like.

Description

technical field [0001] The invention belongs to sanitary ware, in particular to a 3-liter water toilet system. Background technique [0002] Existing water flush toilet, the national standard stipulates that its water sealing depth must not be less than 50mm, because the water sealing depth is high, so flushing resistance is big, must use a large amount of water to just flush clean, 6 liters of water is close to the bottom line of flushing water volume. A toilet with a mechanical seal valve instead of a water trap, although the amount of flushing water is small, is often poorly sealed due to dirt or aging of materials at the mechanical part, and water leakage occurs, resulting in water in the toilet Too little or no, thus affecting the normal use of the toilet. A toilet with trap water seal and mechanical seal at the same time, such as "double anti-odor anti-backflow toilet" (CN2575191Y) only has anti-odor anti-backflow function and does not have water-saving performance, "...

AI Technical Summary

Problems solved by technology

A toilet with a mechanical seal valve instead of a water trap, although the amount of flushing water is small, is often poorly sealed due to dirt or aging of materials at the mechanical part, and water leakage occurs, resulting in water in the toilet Too little or no, thus affecting the normal use of the toilet

A toilet with trap water seal and mechanical seal at the same time, such as "double anti-odor anti-backflow toilet" (CN2575191Y) only has anti-odor anti-backflow function and does not have water-saving performance, "a double-sealed toilet" (CN101245607) Complex structure, troublesome to manufacture and use
