product description:
Above-ground fire hydrant is a type of fire hydrant, and above-ground fire hydrant is an outdoor above-ground fire water supply facility. It is used to supply water to fire trucks or directly connect with hoses and water guns for fire fighting. It is a special facility for outdoor fire fighting water supply. , Its upper part is exposed on the ground, with obvious signs and easy to use. It is composed of valve body, elbow, valve seat, valve clack, drain valve, valve stem and interface. The ground fire hydrant is a kind of necessary fire fighting equipment in cities, especially in urban areas and areas with few rivers, to ensure the fire water supply needs. All factories, mines, warehouses, docks, freight yards, high-rise buildings, public places and other densely accessible areas should be installed if conditions permit.
Technical Parameters:
Nominal diameter: DN100~ DN150mm
Use medium: raw water, clean water
Operating temperature: ≤65℃
Drive mode: manual
Design standards: design and manufacturing standards GB4452-2011, "General Technical Requirements for Outdoor Fire Hydrants", flange connection standards GBT17241.6, "Integral cast iron flanges"
Features:
1. Anti-theft function: Fire hydrant itself should have anti-theft function, anti-theft structure bolt cap design, all fire interface should be anti-theft treatment;
2. Reliable residual water discharge valve: When the main valve flap of the fire hydrant is fully open, regardless of the water pressure in the inner cavity, the residual water discharge valve should be closed tightly, without leakage. When the main valve is closed, the residual water discharge valve should drain smoothly, and the drainage volume is not affected by the water level in the internal cavity of the plug;
3. The miniature suction valve that echoes the residual water discharge valve. When the fire hydrant is in normal use, the suction valve should not leak. When the main valve flap is closed, the suction valve opens quickly, breaking the vacuum of the inner cavity, and cooperating with the drainage action of the residual water exhaust valve. The remaining water is drained in the shortest time, so as to avoid the remaining water cannot be discharged when the weather is cold, causing the fire hydrant to be frozen and cracked.
