Drainage adapter pipe fitting

Abstract

The invention discloses a drainage adapter pipe fitting which comprises an adapter pipe body, the adapter pipe body is provided with at least two water inlets and a water outlet, at least two drainage channels communicated with the water outlet and different water inlets are arranged in the adapter pipe body, and at least one drainage channel is provided with a non-return mechanism. According to the drainage adapter pipe fitting provided by the invention, the non-return mechanism is mounted on at least one drainage channel, so that reverse flow of water can be prevented; the adapter body is provided with at least two drainage channels, so that unsmooth drainage of each drainage pipe caused by mutual influence of water flow can be avoided when a plurality of drainage pipes connected to a plurality of water inlets respectively drain water at the same time, and unsmooth drainage of each drainage pipe caused by mutual influence of water flow can be avoided when a plurality of drainage pipes connected to a plurality of water inlets respectively drain water independently; and water can be prevented from flowing back into other drainage pipes.

Description

technical field [0001] The invention belongs to the field of drainage, and in particular relates to a drainage adapter. Background technique [0002] In the existing drainage adapter with a three-way function, multiple water inlets and drains are connected to each other. When the multiple drains connected to the multiple water inlets are drained simultaneously, they are easily affected by the mutual interaction of the water flow. It will cause the drainage of each drainage pipe to be poor; when multiple drainage pipes connected to multiple water inlets are separately drained, it is easy to make the water flow back into other drainage pipes. When the discharged water is sewage, it is easy to It causes pollution of other drainage pipes; and the drainage port of the existing drainage transfer pipe is not provided with a backflow prevention mechanism, which is prone to the phenomenon of water backflow. [0003] For example, the Chinese patent with the application number of 2019...
