Backflow prevention device
The invention discloses a backflow prevention device. The backflow prevention device comprises a backflow prevention body and a water leakage guide groove, the backflow prevention body comprises a groove body located in the middle, a water inlet end and a water outlet end, and the water inlet end and the water outlet end are located at the two ends of the groove body respectively;the groove body is in the shape of a square box body with an opening at the bottom, the water inlet end and the water outlet end are respectively positioned on the left side wall and the right side wall of the square box body, and a water flow channel is arranged in the water inlet end and the water outlet end and is connected into a cavity of the tank body; the water leakage guide groove is positioned at the bottom of the groove body of the backflow prevention body; the water flow channel of the water inlet end comprises a trumpet-shaped water inlet channel at the water inlet end and a flow stabilizing channel located behind the trumpet-shaped water inlet channel, and the flow stabilizing channel is a pipeline with the same front diameter and rear diameter. Water flow is more stable and not prone to splashing.
本发明公开了一种防回流装置，包括防回流本体和漏水导槽，其中：防回流本体包括位于中部的槽体、分别位于槽体两端的进水端头和出水端头；所述的槽体为底部开口的方形盒体形状，进水端头和出水端头分别位于方形盒体的左右侧壁且内部具有水流通道连接至槽体的空腔内；所述的漏水导槽位于防回流本体的槽体底部；进水端头的水流通道包括进水端的喇叭形的进水通道和位于喇叭口后的稳流通道，所述的稳流通道为前后直径一致的管道。本发明水流更稳，且不易飞溅。
