The invention relates to an energy reducing machine for a drainage system of a house building. The energy reducing machine for the drainage system of the house building comprises a main body, an inletpipe arranged on the upper side of the main body and an outlet pipe arranged on the lower side of the main body. The inlet pipe is provided with a spiral part, and the spiral part can adjust the pitch between spirals according to a first pitch adjustment structure on the outer side of the inlet pipe to adjust the distance from an outlet of the spiral part to the spiral center. At least one fan-blade-shaped structure is arranged at the position, close to the body, of the lower side of the outlet of the spiral part, and the fan-blade-shaped structures can control the rotation resistance. According to the energy reducing machine for the drainage system of the house building, by controlling the water flow speed in a drainage pipe, the pressure on a pipeline can be reduced, the service life ofthe pipeline can be prolonged, and the sound of the water flow can be reduced.
Description
technical field [0001] The invention belongs to the technical field of building water conservancy, and in particular relates to an energy absorber for a building drainage system. Background technique [0002] In the urban underground drainage system, a large amount of sewage flows into the sewage pool through the drainage pipes, and the bottom of the pool will be damaged by the long-term impact of the water flow. Especially in the case of large drainage, the bottom of the pool will bear huge hydraulic impact; , the number of high-rise buildings and ultra-high-rise buildings continues to increase, and the energy-dissipating drainage and sewage pipes in the original design specifications continue to crack and fall off during the current use process. The reason is that almost all high-rise buildings in the original specifications are within 20 floors, while Almost all high-rise buildings now have more than 30 floors. Because the drainage and sewage pipes cannot withstand the p...
