31 is used, so if the water pressure on the water conduit 1 side is always kept constant, which is usually the case, there will be no change in the velocity of the discharged flow, so the water will be mixed with air and generated. The range and foaming performance of the fire extinguishing foam will not be reduced.
すなわち、大放水量時と同一射程、同一発泡性能であり
ながら、放射される消火水泡の量のみ減少させることが
できるのである。In other words, it is possible to reduce the amount of fire extinguishing foam ejected while maintaining the same firing range and foaming performance as when a large amount of water is ejected.

もよい。In addition, in the above embodiment, the needle valve body is 30°31
A hydraulic cylinder 6 was used as the operating means for the fire extinguishing system, but this is because the fire extinguishing water reef is often installed near dangerous objects that humans cannot directly approach in the event of a fire, and the operation is performed remotely. This is based on the consideration that
In addition to the above, a manual operating lever using a lever may also be used.

を落さずに一本の砲身によって放射量を可変できる。As described above, the fire extinguishing water reef according to this invention is provided with a flow rate adjustment means consisting of needle valve bodies 30 and 31 between the water pipe 1 and the nozzle body 7, so that if the water pressure is the same, the nozzle will pass through. The flow rate remains the same, so the amount of radiation can be varied with a single gun barrel without compromising range or foaming performance.
これは、設備費を軽減でき、また設置工事をも簡素化で
きるので、防災上有用なものである。This is useful for disaster prevention because it can reduce equipment costs and simplify installation work.
