A technical solution is provided to address the common industry problem of winter freezing,blockage,and damage to facilities such as urban and rural water supply networks,valves,nozzles,and water meters in cold regions,which causes inconvenience to people's lives and results in a large amount of waste of insulation materials and freshwater resources.By optimizing the internal control of valves and utilizing fluid mechanics theory,comprehensive factors such as flow environment,flow rate,flow velocity,and pressure are effectively utilized.The dynamic design of the internal flow field structure of the valve is adopted to achieve the accumulation,explosion,and ejection of liquid bubbles,generating superimposed secondary forces.Through forward pressure increase and reverse vacuum negative pressure antifreeze,the fluid inside the valve forms a vortex siphon to release air and prevent freezing in low-temperature environments,providing safety guarantees for water use by residents in severe cold and cold areas.Reducing the application of insulation materials and electric heating strips,reducing the probability of pipe valve freezing and blockage,and reducing the waste of water resources and related materials caused by pipeline freezing and cracking,is of great practical significance for the development of energy-saving and anti-freezing technology for building water supply and drainage pipelines.
