Anti-backflow switching valve

An anti-backflow switching valve comprises a pipeline, a water inlet mechanism is installed at the front end of the pipeline, an anti-backflow mechanism for preventing liquid in the pipeline from flowing back is installed at the rear end of the pipeline, a water outlet mechanism is installed at the upper end of the pipeline, and a switching mechanism for adjusting the water flow outlet position of the water outlet mechanism is installed at the lower end of the pipeline. The anti-backflow flushing valve has the advantages that a single-way anti-backflow structure is adopted, the structure is compact, installation is convenient, the space utilization rate is greatly increased, the number of machining steps is small, reliability is high, and the yield is high. 一种防逆流切换阀，包括管道，所述管道前端安装有进水机构，所述管道后端安装有防止管道内液体逆流的防逆流机构，所述管道上端安装有出水机构，所述管道下端安装有调节出水机构水流出水位置的切换机构，本发明有益的效果是：本发明的防逆流冲水阀，采用单路防逆流结构，结构紧凑，安装方便，大大提高了空间利用率，且加工步骤少，可靠性高，良品率高。
