Vane-dissipated stabilized level-adjustable water tank for transient flow in pipelines

Abstract

The invention relates to a blade energy-dissipating stable liquid-level adjustable water tank for pipeline transient flow, comprising a circulating water tank, an overflow water tank and a water collection pipe, the top of the circulating water tank is connected to the bottom of the overflow water tank; The overflow water tank includes an outer box and an inner box arranged in the outer box, the lower end of the outer box and the lower end of the inner box are closed by a bottom surface, and the inner box The lower end is docked with the upper end of the circulating water tank, and the upper end of the inner box is lower than the upper end of the outer box; the water collecting pipe is arranged below the bottom of the overflow water tank, and the water collecting pipe wraps around the The circulating water tank is arranged circumferentially and forms a loop. The water collecting pipe communicates with the bottom surface between the outer box and the inner box through several connecting pipes; an overflow pipe is connected to the water collecting pipe. The invention can overflow at a high liquid level with stable liquid level and little disturbance.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a pressurized pipeline water supply device, and more particularly to a blade energy dissipation type stable liquid level adjustable water tank for pipeline transient flow. Background technique [0002] In modern hydraulic pipeline systems such as large-scale water transfer and heating pipe networks, safe and reliable fluid transport is required. Pressure water pipelines are an important part of these key infrastructures. Due to sudden pump stop, valve closure and other misoperations, transient cavitation flow accompanied by rapid changes in flow rate and pressure may be generated in the pipeline. During the transient cavitation flow process. The resulting low pressure and pressure fluctuations dozens or even dozens of times higher than the normal working pressure of the pipeline will have a significant impact on the safe and stable operation of the pipeline ...

AI Technical Summary

Problems solved by technology

The existing overflow water tank has either unstable flow, strong disturbance, or insufficient liquid level, and cannot adjust the liquid level of the water tank according to the demand, so there are still great shortcomings
