One-way exhaust valve with drainage function
The invention relates to the technical field of water conservancy projects, in particular to a one-way exhaust valve with a drainage function. The one-way valve comprises an upper vertical pipe and a one-way valve body arranged at the top of the upper vertical pipe, an upper flange abutting against an impermeable film is arranged at the bottom of the upper vertical pipe, a lower vertical pipe is arranged below the impermeable film corresponding to the position of the upper vertical pipe, a lower flange is arranged at the top of the lower vertical pipe, and the upper flange is connected with the lower flange through a plurality of bolts. The device is reasonable in structural design, and can carry out a precipitation process during the construction period of the impermeable membrane of the plain reservoir, so that the underground water level is reduced to be below the impermeable membrane, and smooth construction of a leveling layer, a membrane paving layer and a ballasting layer is ensured; after the precipitation process is completed, the precipitation equipment can be easily taken out, the repeated utilization rate of the precipitation equipment is increased, the anti-seepage film cannot be damaged, potential hazards caused by deep burying underground to the anti-seepage film are avoided, and the problems existing in the prior art are solved.
本发明涉及水利工程技术领域，尤其涉及一种具有排水功能的单向排气阀。它包括上立管和设置在上立管顶部的单向阀本体，在上立管底部设有抵接在防渗膜上的上法兰，在对应上立管位置的防渗膜下方设有下立管，在下立管顶部设有下法兰，上法兰通过若干个螺栓与下法兰相连。它结构设计合理，可在平原水库防渗膜施工期间进行降水工序，使地下水位降低到防渗膜下方，从而保证整平层、铺膜、压重层的顺利施工；待降水工序完成后，不仅可以轻松对将降水设备取出，提高其重复利用率，还不会破坏防渗膜，并解决了深埋地下对防渗膜造成的潜在隐患，解决了现有技术中存在的问题。
