Anti-backflow sewage transportation pipeline
The invention discloses an anti-backflow sewage transportation pipeline. The anti-backflow sewage transportation pipeline comprises a sewage transportation pipe body and a mounting pipe connected to the sewage transportation pipe body, wherein an anti-backflow device is detachably mounted on the inner side wall of one end of the mounting pipe, the anti-backflow device comprises a telescopic rod main rod fixedly mounted in the mounting pipe, a telescopic rod auxiliary rod is movably inserted into one end of the telescopic rod main rod, a sealing ball is fixedly installed at one end of the telescopic rod auxiliary rod, first springs are evenly wound around the outer side wall of the telescopic rod auxiliary rod, and the two ends of each first spring are fixedly installed on the telescopic rod main rod and the sealing ball correspondingly. According to the anti-backflow sewage transportation pipeline, the anti-backflow device can be fixedly mounted in the mounting pipe or dismounted fromthe mounting pipe conveniently, so that the anti-backflow device can be replaced conveniently after the elasticity of the springs become poor, the situation that the anti-backflow effect of the sewagetransportation pipeline is sharply reduced due to the fact that the elasticity of the springs become poor can be avoided, the design is reasonable, and the practical effect is good.
本发明公开了一种防回流的污水运输管道，包括污水运输管和连接在污水运输管上的安装管，安装管一端的内侧壁上拆卸安装有防回流装置，防回流装置包括固定安装在安装管内的伸缩杆母杆，伸缩杆母杆的一端活动插设有伸缩杆子杆，伸缩杆子杆的一端固定安装有密封球，伸缩杆子杆的外侧壁上均匀绕设有第一弹簧，且第一弹簧的两端分别固定安装在伸缩杆母杆和密封球上。本发明中可以方便的将防回流装置固定安装至安装管内或从安装管内拆出，因此当弹簧的弹性变差后可以方便的对防回流装置进行更换，从而能避免由于弹簧弹性变差而导致污水运输管道的防回流效果急剧下降，设计合理，实用效果好。
