Description

Technical Field

[0001] This utility model belongs to the field of fire hose technology, specifically a piercing demolition hose device. Background Technology

[0002] Fire hoses are the core water-spraying tools in fire-fighting water supply systems. By connecting with equipment such as fire hoses and fire pump sets, they transform pressurized water flow into a specific jet shape for extinguishing fires, cooling and protecting, diluting toxic gases, or dispersing smoke. They are indispensable key equipment in fire fighting. Their design must meet four core requirements: high pressure resistance, adjustable flow rate, stable jet, and convenient operation. Their working principle is that the pressurized water provided by the fire pump is delivered to the hose interface of the hose. After being depressurized / stabilized by the flow channel inside the hose, the water flow is transformed into a direct stream, spray, water curtain, or other forms by the nozzle. The kinetic energy of the jet impacts the flames, isolates oxygen, or dilutes flammable media to achieve the purpose of extinguishing the fire.
