Anti-freezing drainage downpipe
The invention relates to the technical field of pipelines, in particular to an anti-freezing drainage downpipe. The anti-freezing drainage downpipe comprises a downpipe body and a drainage pipe drain, the downpipe body is fixedly installed on the outer wall face through a pipe clamp, the downpipe body at the corner of the wall face is connected through a bent pipe, and the drainage pipe drain is installed on the downpipe body at the top of the wall face. According to the anti-freezing drainage downpipe, a PVC base pipe is coated with an RTV anti-pollution flashover coating layer, so that damp and dirty water is effectively prevented from entering the PVC base pipe, and it is guaranteed that the PVC base pipe is not prone to corrosion; meshing teeth on a flame-retardant fiber sleeve have the anti-gnawing effect on rodents, and therefore damage of the rodents is effectively resisted; and a buffer piece is additionally arranged, so that the hidden danger of threaded connection failure caused by vibration of a buffer pipe and a filter pipe can be eliminated in the structural form, the sealing effect between the buffer pipe and the filter pipe and the long-term sealing effect are also ensured, and meanwhile, the downpipe body is also protected.
本发明涉及管道技术领域，尤其涉及一种防冻排水落水管。所述防冻排水落水管包括落水管体和排水管漏，所述落水管体通过管卡固定安装在外墙面上去，且墙面拐角处的落水管体通过弯管连接，所述排水管漏安装在墙面顶部的落水管体上。本发明提供的防冻排水落水管在PVC基管上涂覆的RTV防污闪涂料层有效阻隔潮湿脏污的水液进入到PVC基管中，保证了PVC基管不易腐化，在阻燃纤维套上的啮合齿对啮齿类动物起到防啃噬作用，因此有效抵御啮齿类动物的破坏，而增设缓冲件可以在结构形式上消除了因为缓冲管和过滤管的振动造成螺纹连接失效的隐患，也保证了缓冲管和过滤管之间的密封效果和密封的长效性，同时也保护了落水管体。
