The cutting that described abrasive material mixes in the rifle body dual-purpose spray gun of putting out a fire is characterized in that: high pressure nozzle 1 adopts the silicon sulfide material, embeds in the nozzle holder 2.
The cutting that described abrasive material mixes in the rifle body dual-purpose spray gun of putting out a fire is characterized in that: abrasive material fluidisation nozzle 5 adopts the skewed slot forms, mixes at annular fluidization regions a inner high voltage water and abrasive material.
The cutting that described abrasive material mixes in the rifle body dual-purpose spray gun of putting out a fire is characterized in that: the dismantled and assembled property of the portability of abrasive can, rule of thumb the small design abrasive can convenient and reliable operation that is.
The cutting that described abrasive material mixes in the rifle body dual-purpose spray gun of putting out a fire is characterized in that: trigger 10 control small valve core b, small valve core b promotes big valve core c through control and easily opens high-pressure stop valve 9.
Than other similar High Pressure Guns, its advantage is simple for structure, and volume is little in light weight, and the cutting fire-fighting efficiency is high, and is easy to manufacture, reduces particularly that sand grains is to the fretting wear of control valve in the like product, and cost is low, and it is convenient etc. to maintain.
