Horizontal one-way pipeline valve preventing returned water from flowing backwards

Abstract

A horizontal one-way pipeline valve preventing returned water from flowing backwards is mounted between an in-building main pipeline and each single household pipeline and is mounted on all water outlet pipes, leading to a sewer, a covered drain, a river and the like, of rooms of a factory, a garage, a private house and the like. According to the purposes, the phenomenon that due to blockage of amain pipeline on a certain segment in a building, output water of an upper resident flows backwards to enter a lower resident to cause troubles, and the life is affected is avoided; the phenomenon that due to the fact that water levels in the river, the covered drain and the sewer suddenly rise and flow to the room backwards, and property losses are caused is avoided; a pipeline valve shell (1) isin a cylindrical shape, a water inlet (1-1) and a water outlet (1-2) are connected with the two ends of the pipeline valve shell (2), the inner diameter of the water inlet (1-1) and the water outlet(1-2) is the same with the outer diameter of the pipeline valve shell, similarly, an outer connection pipe and water flow marks (1-3) of a common pipeline are designed on the top, the arrow type is achieved, horizontal marks (1-4) are designed on the left side and the right side of the pipeline valve shell (1), the arrows are upward, a valve (2) is mounted in the pipeline valve shell (1), one faceis perpendicular, the other face is designed to be a slope (2-1), and a water passing hole (2-2) is formed in the middle of the valve body (2).

Description

technical field [0001] The invention relates to "a horizontal one-way pipeline valve for preventing backwater backflow". It looks like the outer junction of ordinary pipes, and can be directly connected to common pipes. It is installed between the main pipe and household pipes in the building. Its purpose is to prevent a certain section of the main pipe from being blocked. Leakage from toilets, floor drains, and washbasin sewer pipes will have an impact on indoor safety. Background technique [0002] At present, the water pipes of the toilets of the residents living in the upper floor are directly connected to the vertical main pipe. Once a certain section of the main pipe is blocked, the water from the upper households will flow back into the lower households and come out from the mouth of the toilet, floor drain, and washbasin. The normal life of the residents; in addition, the internal outlet pipes of the bottom-floor residents, ordinary houses, warehouses, factories, et...

AI Technical Summary

Problems solved by technology

[0002] At present, the water pipes of the toilets of the residents living in the upper floor are directly connected to the vertical main pipeline. Once a certain section of the main pipeline is blocked, the water from the upper households will flow back into the lower households and come out of the toilets, floor drains, and washbasins. The normal life of the residents; in addition, the internal water outlet pipes of the ground floor residents, ordinary houses, warehouses, factories, etc. lead to sewers, gutters, and river drainage. , The sewer pipe of the washbasin emerges, which will completely affect the internal safety of the room, garage, and factory
