High-pressure water drainage control method and high-pressure fire water monitor

Abstract

The invention discloses a high-pressure water drainage control method and a high-pressure fire water monitor. In the control method, a water guide pipeline with the polygonal cross section and sectional area reduced gradually is adopted for preparing the high-pressure fire water monitor. The end with the smaller cross sectional area of the water guide pipeline is a water outlet, the water outlet is provided with a control head capable of adjusting the opening of a water drainage channel, an edge slot in the water guide pipeline with the polygonal cross section can guide water to flow towards the water outlet, water flow vortex formed in the pipeline are reduced, friction between the water flow and the inner wall of the water guide pipeline is reduced, energy loss of water flow end flow isreduced, water drainage energy is improved, water drainage pressure or amount is further controlled by means of adjustment of the control head to the opening of the water drainage channel, and the high-pressure water jet range is increased.

Description

technical field [0001] The invention relates to fire-fighting consumables, in particular to a high-pressure water outlet control method and a high-pressure fire-fighting water cannon obtained based on the above-mentioned method. Background technique [0002] The fire water cannon is an important part of fire extinguishing. It is installed at the outlet end of the fire hose to adjust the water flow in the hose to spray water at a high speed, thereby increasing the fire extinguishing range of the fire hose. At present, the aqueducts of fire water monitors in the market are mostly cylindrical structures with tapered cross-sections. The tapered cross-section can effectively increase the speed of water flow in the aqueducts. At the same time, serious turbulence phenomenon also occurs. Specifically, when the water flow flows in the water pipe, a vortex will be formed, and the formation of turbulent flow will consume a certain amount of energy of the water flow, which will make the...

At present, the aqueducts of fire water monitors in the market are mostly cylindrical structures with tapered cross-sections. The tapered cross-section can effectively increase the speed of water flow in the aqueducts. At the same time, serious turbulence phenomenon also occurs. Specifically, when the water flow flows in the water guide pipe, a vortex will be formed, and the formation of turbulence will consume a certain amount of energy of the water flow, which will make the water cannon insufficient energy and high-speed radial spraying, which will affect the high-pressure water spraying. range, the existing fire water cannons need to be improved
