Technical Field
The utility model relates to a pipeline technical field, concretely relates to pressure water delivery pipeline and have its pressure water delivery system.
Background
The pressurized water conveying means that water is conveyed by a pressure-bearing pipeline in a pressure flow mode. The method is suitable for the conditions of low water plants (or water supply areas) in the terrain of water sources according to the specific conditions of terrain height difference, pipeline length, pipeline pressure bearing capacity and the like.
In order to meet the urban construction of cities, a long-distance pressurizing water delivery mode is adopted in many cities. In the operation of the long-distance pressurized water conveying pipeline, due to certain external reasons, such as sudden closing of a valve, sudden stopping of a water pump unit and the like, the flow rate of water is suddenly changed, and a very high negative pressure value can be generated in the pipeline instantly. When the valve is suddenly opened, the water flow is instantly fast, and high positive pressure can be generated in the pipeline. In order to meet the use requirement, the urban water conveying pipeline is a metal pipeline or a hard plastic pipeline, and the high negative pressure and the high positive pressure are both easy to cause the deformation and the damage of the pipeline and influence the whole water conveying system.
