Fire Hose Landing Valve is an important part of the fire extinguishing system and is used to provide fire extinguishing water source.
Identify Valve Locations: Determine the location of landing valves, typically they are installed in stairwells, hallways, or other easily accessible areas of the building. The valve is usually located at the bottom of the valve body and has a handle or knob that controls the opening and closing of the valve.
Check status: Before using the landing valve, make sure the valve is closed. This can be confirmed by checking the position of the handle or handle.
To open the valve: Turn the handle or knob counterclockwise to open the valve. This will allow water from the building's water system to flow into the fire hose.
Connect the hose: Insert the connector of the fire hose into the interface of the landing valve. Typically, the joint rotates or locks in place to ensure a secure connection.
Turn on the hose: Open the valve on the fire hose, which is usually a handle or knob. This allows water to flow through the landing valve and be supplied via a hose to the nozzle or gun.
Use fire-fighting equipment: Point a nozzle or spray gun at the source of the fire and use water to extinguish the fire. Pay attention to using the correct water spray method, such as cone spray, to increase the fire extinguishing effect.
Close the valve: After the fire extinguishing task is completed, close the valve on the fire extinguishing hose. Then, turn the landing valve handle or knob counterclockwise to close the landing valve valve.
Check valve status: After closing the valve, make sure the handle or handle has returned to the closed position to prevent unnecessary water flow.
The above steps provide general guidelines for using the Fire Hose Landing Valve, but please note that specific usage may vary by manufacturer and model. In all cases, specific instructions provided by the manufacturer should be followed and the user must have basic knowledge of the operation of the fire extinguishing equipment. In addition, it is recommended that professional fire fighting work be performed by trained fire fighters.
