Manual fire nozzles, normal pressure, shut-off ROCNIK NA ZASUN and ROCNIK NA ZASUN S PLASTICNO CEVJO are designed to form and direct a solid or spray stream when extinguishing a fire.
The barrels are equipped with a nozzle with a diameter of 12 mm. The shut-off valve is made in the form of a ball, in which a turbulator is built in, by means of which a spray jet is formed. Figures 1 and 2 show the barrels ROCNIK NA ZASUN with a pipe made of aluminum alloy and ROCNIK NA ZASUN S PLASTICNO CEVJO with a pipe made of plastic, respectively.
The aluminum alloy pipe has a heat-insulating coating of colored corrugated plastic on the outside.
Main indicators and characteristics:
| Name of the indicator | Value of the indicator |
| Working pressure, MPa | 0.4-0.7 |
| Continuous jet flow rate, l . s -1 | 3.0 |
| Range of continuous jet, m | 30 |
| Spray flow rate, l . s -1 | 2.0 |
| Spray range, m | 11 |
| Effective range of spray jet, m | 5 |
| Average intensity of spray jet irrigation, l . s -1. m 2 | 0.09 |
| Spray jet angle, degrees | 37 |
Note : the water supply performance indicators are given at a working pressure in front of the barrel of 0.4 (+0.05) MPa.
The barrel is manufactured in the UHL climate version, category 1.1 according to GOST 15150. The total service life is 10 years.
