High Speed Water Mist Nozzle

High Velocity Water Spray Nozzles are internal swirl plate type open nozzles designed for use in fixed water spray or deluge system for the fire protection application.
These nozzles produce solid uniform and dense core of high velocity water spray to effect fire control. Nozzles are normally used to cool the surface as well as for extinguishment. Nozzles are typically used for Deluge protection of special hazards such as oil filled transformers, switch-gear, chemical process equipment, conveyor system and flammable liquid storage areas. The minimum desirable pressure to achieve a reasonable spray pattern is 3.5 Kg./sq.cm. (50 psi).

KEY POINTS

Function: HVWS nozzles are used to disperse water in a high-velocity spray pattern to cool and extinguish fires in high-risk areas.   They are commonly used in applications such as flammable liquid storage areas, transformer vaults, aircraft hangars, and some industrial processes.

Characteristics: High Velocity Water Spray nozzles typically feature a unique design with a specialized orifice, internal baffles, and flow straightening vanes.   These components work together to create a pressurized water jet with a narrow spray pattern and high momentum, which helps in penetrating flames and delivering efficient fire suppression.

Fire Protection: HVWS systems are designed to provide rapid cooling and control of fires.   The high-velocity water spray can quickly absorb heat from flames, lower the temperature of the surrounding area, and create a barrier of cooling water.

Nozzle Placement: The placement of HVWS nozzles is critical to their effectiveness.   They are strategically installed to provide coverage over the protected area, typically in overhead positions.   The spacing and arrangement of nozzles should be based on the specific fire hazards and requirements of the installation.

Activation: HVWS systems can be activated in several ways, depending on the fire detection system used.   They may be connected to a fire alarm panel, heat or smoke detectors, or manual release stations.   When a fire is detected, the system activates, and water is discharged through the HVWS nozzles.

Design Considerations: The design of a HVWS system should consider factors such as the type and size of the protected area, fire hazards, flow rates, water supply requirements, and local fire protection codes and regulations.
