Technical Field

[0001] The utility model relates to the field of water outlet energy dissipation after a cone valve, in particular to a short-distance composite energy dissipation pool used after a cone valve. Background Art

[0002] In many engineering fields such as water conservancy and municipal engineering, the energy dissipation of water after the cone valve is involved. Some of the cone valves are behind existing rivers (or pipelines), and the water from the cone valve is easy to cause scouring, so an energy dissipation solution is needed to dissipate the energy of the water. Since it is difficult to acquire land for current projects, a short-distance energy dissipation solution is urgently needed. At the same time, it is necessary to consider the sediment deposition that is easy to cause after energy dissipation, which can improve the convenience of the operation period and reduce the operating cost.

[0010] The utility model provides a short-distance composite energy dissipation pool for use behind a cone valve, which has the following beneficial effects:

[0011] 1. After the water from the cone valve is initially dissipated through the energy dissipation block at the bottom, the overflow or splashing water is dissipated for the second time through the diversion effect of the diversion pier. After the energy dissipation pool is used many times, there will be sediment deposited at the bottom of the pool. Open the sand discharge hole and flap the door, and the water in the energy dissipation pool 1 will be discharged from the sand discharge hole, discharging part of the sediment and reducing sediment deposition.

[0012] 2. The water outlet direction of the cone valve can be easily adjusted by setting a water outlet adjustment cover.
