Product Characteristics
Appearance and Structure
It is generally composed of main components such as a fire hydrant box, a fire hose nozzle, a fire hose, and a fire hydrant valve. The whole is installed on the interior walls and other locations for easy access. The fire hydrant box is usually red with the words "Fire Hydrant" clearly marked on the surface, making it easy to identify.
The materials of the box door are diverse, including aluminum alloy, glass, etc. It is equipped with a door lock or a push - type opening device, which can be quickly opened.
Material Performance
Key components such as the fire hydrant valve and pipeline interfaces are generally made of copper or stainless steel, which have good corrosion resistance and pressure resistance. This ensures that normal functions will not be affected by problems such as rust and corrosion during long - term use.
Fire hose nozzles are usually made of high - strength plastic or metal, which can withstand a certain pressure and ensure the water spray range and spraying effect. Fire hoses are generally made of materials such as rubber and nylon, which have good flexibility, wear resistance, and water resistance. They can be quickly deployed and convey a large amount of water flow.
Operational Performance
It is simple and convenient to operate. When a fire occurs, just open the fire hydrant box door, press the fire button to start the fire pump, then take out the fire hose nozzle and the hose. Connect one end of the hose to the fire hydrant valve, and the other end to the nozzle. Open the fire hydrant valve to spray water for fire extinguishing.
The opening and closing of the fire hydrant valve are flexible, with a small rotation torque, which is convenient for firefighters to operate quickly in an emergency.
Specifications
Fire Hydrant Valve
- Nominal Diameter: Commonly, there are two specifications, DN65 and DN50. The DN65 fire hydrant valve is suitable for large - flow fire water demand and is generally used in large - scale buildings, industrial plants, and other places. The DN50 fire hydrant valve is suitable for some small - scale buildings or places with relatively small fire water demand.
- Working Pressure: Generally, there are different pressure levels such as 1.0 MPa and 1.6 MPa to meet the pressure requirements of different building heights and fire protection systems.
Fire Hose Nozzle
- Nozzle Diameter: Commonly used specifications are 16 mm and 19 mm. The 16 - mm nozzle is suitable for extinguishing fires in general buildings, with a relatively moderate water flow range and flow rate. The 19 - mm nozzle has a larger flow rate and a farther range, which is suitable for extinguishing larger - area or higher - position fires.
- Material and Length: The materials include plastic, aluminum alloy, etc. The length is generally between 300 mm and 600 mm, which is convenient for firefighters to hold and operate.
Fire Hose
- Nominal Diameter: Mainly DN65 and DN50, which match the specifications of the fire hydrant valve and the nozzle.
- Length: Common length specifications are 20 m, 25 m, 30 m, etc. The 20 - m and 25 - m hoses are more commonly used. The appropriate length can be selected according to the building layout and actual needs.
- Working Pressure: Generally, there are different pressure levels such as 0.8 MPa, 1.0 MPa, and 1.3 MPa to adapt to the pressure of different fire protection systems and fire - extinguishing requirements.
Indoor fire hydrant products produced by different manufacturers may have certain differences in specific dimensions and materials, but overall, they should comply with relevant national standards and industry specifications.
