Therefore, the utility model/invention adopts the following technical proposal:
a water spray fire-fighting system suitable for cold areas comprises a deluge valve water inlet pipe, a deluge valve water outlet pipe and a deluge valve group, wherein the deluge valve water inlet pipe is provided with a deluge valve front valve, a filter and a deluge valve front pressure gauge, and the deluge valve water outlet pipe is provided with a deluge valve rear pressure gauge and a pressure switch; the water spray fire-fighting system is characterized by further comprising an anti-freezing drain pipe, an anti-freezing drain pipe valve is arranged on the anti-freezing drain pipe, one end of the anti-freezing drain pipe is connected with the water outlet pipe of the deluge valve, the other end of the anti-freezing drain pipe is connected with the water leakage pipe of the deluge valve, and the deluge valve group, the front valve of the deluge valve, the filter, the front pressure gauge of the deluge valve, the rear pressure gauge of the deluge valve, the pressure switch, the anti-freezing drain pipe and the anti-freezing drain pipe valve are arranged in a room with a heating device.
On the basis of adopting above-mentioned technical scheme, the utility model discloses still can adopt following further technical scheme, or to these further technical scheme combined use:
the heating device adopts an electric heater.
The room is a brickwork room.
The anti-freezing drain pipe is connected to the water leakage pipe of the deluge valve through a tee joint and is connected by welding.
The water leakage pipe of the deluge valve is connected with the accident oil discharge main pipe and is connected in a welding mode, and therefore the problem of field water discharge is solved.
The accident oil discharge main pipe is a hidden project and is buried underground or arranged in a pipe ditch.
The inlet of the anti-freezing water pipe is positioned at the lowest part of the water outlet pipe of the deluge valve; the height of the water discharge pipe is lower than that of the bottom ring pipe of the water spray pipe network.
The valve of the anti-freezing drain pipe adopts a manual ball valve, and the opening of the manual ball valve can be adjusted to control the drainage flow.
The utility model relates to a simple reliable has improved water spray fire extinguishing systems's security and reliability, and maneuverability is strong, and the investment accounts for than not big, and the outdoor severe cold area of specially adapted has fine application prospect in water and electricity, new forms of energy, petrochemical field.
