ZSTWB inner wire high-speed water mist nozzle, water mist nozzle national standard

.Inner wire high-speed water mist nozzles
. Internal wire high-speed water mist nozzles are also called centrifugal water mist nozzles. They are usually used in dry deluge systems, ammonia tank dilution, fire dry systems, warehouses, and liquefied gas. Tanks, oil tanks, ships, distribution boxes, machine rooms, transformers, warehouses, shopping malls, and other special places, it can also be used in cooling, dust removal, isolation, and fire extinguishing environments.
. Internal wire high-speed water mist nozzle
.Principle
. This series of water mist nozzles decomposes the water flow of a certain pressure into two streams, one of which moves along the inner wall and has a centrifugal speed. Rotating water flow. The other stream is a straight stream with axial velocity. The two streams of water merge at the nozzle of the nozzle. They are ejected from the nozzle at their combined speed to form atomization. The sprayed water mist is relatively uniform and uniform according to a certain atomization angle. Ground spray onto the outer surface of the protected object to achieve cooling and suffocation, control fires and extinguish fires. Centrifugal atomizing core
. High-speed inner wire
. The main internal parts of the water mist nozzle are divided into two-hole cross type and four-hole rotating type. The flow rate and the diameter of the atomized water droplets are different. The cross-hole type divides the water into two paths at right angles, reflects the impact and then sprays out, while the four-hole rotation type divides the water into four paths, impacts them together when rotating to the bottom, and then sprays out.
