Description

Technical Field

[0001] The utility model relates to the technical field of water delivery pressure reducing valves, in particular to a force dissipation and pressure reducing device for a long-distance water delivery and regulation system. Background Art

[0002] During the water transmission process of long-distance pressurized water pipelines, when the terrain changes greatly from high to low, the huge height difference will increase the head pressure on the water pipeline. If no corresponding pressure reduction measures are taken, it is necessary to increase the pressure resistance level of the water pipeline itself, resulting in an increase in project costs and operation and maintenance costs. In order to avoid the problem of increased costs due to excessive pressure in the pipeline resulting in an excessively high pressure resistance level, a certain number of pressure reducing valves are usually set according to a certain height difference based on the actual situation of the project to reduce the pressure of the water pipeline.

[0003] Because the pressure reducing valve is installed on the water pipeline, with the head and tail ends connected to the water pipeline to ensure smooth water flow, traditional valve wells are usually buried. When the groundwater level is high or it rains, the water pipeline passing through the valve well wall may cause water seepage if the location is not properly handled. The water flow often carries a certain amount of solid particles such as mud and sand. If not properly handled, the service life of the pressure reducing valve will be greatly reduced. Therefore, a force-dissipating and pressure-reducing device is needed to solve this problem in long-distance water transmission and diversion systems. Utility Model Content
