Sewage backflow prevention water tank drainage assembly
The invention discloses a sewage backflow prevention water tank drainage assembly which comprises a filter basket and a shell. The lower end of the shell is connected with a drainage pipe, the upper end of the drainage pipe is sleeved with a pressure sleeve, the pressure sleeve is in threaded connection with the lower end of the shell, the upper end of the drainage pipe is tightly pressed at the lower end of the shell through the pressure sleeve, and a second sealing ring is embedded between the upper end of the drainage pipe and the lower end of the shell; the lower end of the drainage pipe is inserted into a blow-off pipe, the lower end of the drainage pipe is sleeved with a rubber ring, the inner peripheral wall of the rubber ring is in interference fit with the outer peripheral wall ofthe drainage pipe, the lower end of the rubber ring is inserted into the blow-off pipe, the upper end of the rubber ring is provided with an annular bending edge, a plurality of annular convex ribs distributed from top to bottom are integrally formed on the outer peripheral wall of the rubber ring positioned inside the blow-off pipe, and the outer edge of each annular convex rib is in close fit with the inner peripheral wall of the blow-off pipe. The assembly can prevent sewage from flowing back out of a gap between the drainage pipe and the blow-off pipe, thereby avoiding bringing inconvenience to users.
本发明揭示一种防污水反涌的水槽排水组件，包括过滤篮和壳体，壳体的下端连接有排水管，排水管上端的外部套装有压套，压套与壳体的下端螺纹连接，排水管的上端通过压套压紧在壳体的下端，排水管上端与壳体的下端之间嵌装有第二密封圈；排水管的下端插入在排污管中，排水管下端的外部套装有橡胶圈，橡胶圈的内周壁与排水管的外周壁过盈配合，橡胶圈的下端插入在排污管中，橡胶圈的上端设置有环形折弯边，位于排污管内部的橡胶圈的外周壁上一体成型有若干道由上至下分布的环形凸筋，每道环形凸筋的外边缘均与排污管的内周壁紧配合；本发明能够避免污水从排水管与排污管之间的空隙反涌出来，从而能够避免给用户带来不便。
