Blade energy dissipation type stable liquid level adjustable water tank for pipeline transient flow

Abstract

The invention relates to a blade energy dissipation type stable liquid level adjustable water tank for pipeline transient flow, which comprises a circulating water tank, an overflow water tank and a water collecting pipe, and the top of the circulating water tank is connected with the bottom of the overflow water tank; the overflow water tank comprises an outer tank body and an inner tank body arranged in the outer tank body, the lower end of the outer tank body and the lower end of the inner tank body are sealed through a bottom face, the lower end of the inner tank body is in butt joint with the upper end of the circulating water tank, and the upper end of the inner tank body is lower than the upper end of the outer tank body; the water collecting pipe is arranged below the bottom of the overflow water tank, the water collecting pipe is arranged in the circumferential direction of the circulating water tank to form a loop, and the water collecting pipe communicates with the bottom surface between the outer tank body and the inner tank body through a plurality of connecting pipes; and the water collecting pipe is connected with an overflow pipe. The blade energy dissipation type stable liquid level adjustable water tank can achieve high-liquid-level overflow, and the liquid level is stable and small in 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 specifically to a blade energy-dissipating stable liquid-level adjustable water tank for pipeline transient flow. Background technique [0002] In modern hydraulic pipeline systems such as large-scale water transmission and transfer, heating pipe network, etc., it is necessary to transport fluid safely and reliably. Pressure water pipelines are an important part of these critical infrastructures. Misoperations such as suddenly stopping pumps and closing valves may cause transient cavitation flows in the pipelines accompanied by sharp changes in flow velocity and pressure. During transient cavitation flows The resulting low pressure and pressure fluctuations that are tens or even tens of times higher than the normal working pressure of the pipeline will have a major impact on the safe and stable operation o...

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
