The utility model discloses a spiral type water-splashing-preventing exhaust valve which aims at solving the problems that after an exhaust valve exhausts air, liquid is prone to rising or splashing in a small range under the action of pressure, and in some special application scenes, splashed liquid may bring serious consequences. The device comprises an outer shell and a spiral pipeline, the outer shell is of a big-end-up two-section type hollow columnar structure, the upper end of the outer shell is an outer shell cavity, and the lower section of the outer shell is an exhaust inlet. And the spiral pipeline is arranged in the cavity of the outer shell. Liquid is dredged through the spiral pipeline, a liquid moving space is provided, the water hammer effect is reduced, the liquid splashing risk is effectively reduced, and personal safety is protected. 本实用新型公开了一种螺旋型防水喷溅式排气阀，以解决排气阀在排空气体后，液体容易在压力的作用下小幅度上涨或喷溅，在一些特殊应用场景之下溅出的液体可能会带来严重的后果的问题；本实用新型包括外壳体和螺旋管道；所述外壳体为上大下小两段式中空柱状结构，上端为外壳体腔室，下段为排气进口；所述螺旋管道设于外壳体腔室中。利用螺旋管道
