Reducing water pipe steam mixing super-cavitation pipeline explosion leakage inhibiting device

Abstract

The invention relates to a novel reducing water pipe steam mixing super-cavitation pipeline explosion leakage inhibiting device. The device is characterized in that steam with high pressure in small pipe diameters in a reducing water pipe is introduced to a pipe diameter change outlet of a reducing water pipe through a bypass pipe, so that steam mixing is carried out on water containing cavitation bubble groups and air bags at the pipe diameter change outlet, the local pressure of a steam mixing area is improved, the cavitation number is effectively reduced, the pressure during collapse of the cavitation bubbles and the air bags is remarkably reduced, the super-cavitation state is formed, the water hammer blocking and closing phenomenon is greatly reduced, and therefore the water pipe burst problem is reduced. Water vapor in the bypass pipe converges with supplied water and then flows back into the water pipe, so that urban pipe network water supply circulation is completed. Compared with a traditional water pipe anti-explosion and water leakage reducing device, the device has the advantages of being simple in structure, convenient to machine and install, low in later maintenance cost and the like. The device is not only suitable for common urban water transportation and distribution pipelines, but also can be adopted for water supply pipelines in the fields of machinery, chemical engineering, artificial environment and the like.

Description

technical field [0001] The present invention relates to the technical field of urban pipe network water supply, in particular to a new type of steam-mixed supercavitation suppressing pipe explosion leakage device for water pipes with different diameters. A water pipe layout method in which water pipes of different diameters are connected. The steam-mixed supercavitation suppressing pipe leakage device of the different-diameter water pipe is a water vapor with a relatively high pressure in the small-diameter water pipe of the different-diameter water pipe that is introduced into the At the outlet of the diameter change of the water pipe with different diameters, the water containing cavitation groups and air pockets at the outlet of the diameter change can be mixed with steam to increase the local pressure in the steam mixing area, effectively reduce the number of cavitation, and significantly reduce the collapse of cavitation and air pockets The pressure at the time of extingu...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to design a water pump that does not affect its water flow transmission in view of the technical problems of the existing urban water supply pipe network, such as pipe bursts and serious water leakage, and the difficulty of installing exhaust valves in traditional different-diameter pipes. Effective, and easy to implement, it can effectively reduce the breakage of different-diameter water pipes and bridge the water hammer phenomenon, thereby improving the water resource utilization rate of the entire urban water supply network, reducing the maintenance cost of water pipes and ensuring the normal operation of the water supply system.
