SSFT100/65-1.6 SNFD above-ground outdoor fire hydrant, φ100m water outlet is exclusively for fire trucks to absorb water, φ65m double outlet is connected to the hose, and then discharges water for fire fighting.
1. Fire fighting: In the event of a fire, first use the special wrench of this product to fully open the 65 water outlet plugs at both ends, connect the spare hose and water gun (or other fire extinguishing device), and then use the special wrench clockwise Turn on the control lever at the top of this product, and the fire water can be used to extinguish the fire through the water gun (or other fire extinguishing device). Open the 100 water outlet to fill the fire truck.
2. Antifreeze: The opening method of this product is the lifting shaft opening, which is labor-saving and convenient when opening. After the fire is complete, use a special wrench to turn the operating rod counterclockwise to the end, and the water in the plug above the frozen layer will instantly drain to achieve the antifreeze function.
3. Anti-collision: After the fire hydrant receives a sudden impact from the outside, the anti-collision disc part will automatically detach due to the transverse shear force. The lower locking valve will automatically lock the water supply source after sensing the impact to ensure no water leakage. In order to prevent the pressure drop of the pipe network from affecting nearby fire fighting. It can be repaired by replacing the anti-collision disk. Shorten the repair time and reduce labor intensity.
4. Pressure regulation: The fire hydrant is designed to be opened in stages, and can be opened easily with one-hand operation under pressure. When opening, the connecting rod inside the fire hydrant moves vertically downwards, through the shut-off aperture of the water outlet area of the sliding pressure reducing and stabilizing device, More water is delivered to the water outlet of the fire hydrant, and the pressure gradually increases until the main valve of the fire hydrant is fully opened, thereby achieving the effect of pressure reduction, stabilization and pressure regulation of the fire hydrant. It can be used for low pressure canning and high pressure fire fighting.
5. Anti-theft: strong magnetic lock, special encryption wrench can be opened to prevent water theft. At the same time, the pressure drop of the surrounding fire piping system caused by water theft is avoided.

|Design work pressure||1.6MPa||1.0MPa|
|Specification and quantity of outlet||KWS65-2 pcs||KWS65-2 pcs|
|Outlet joint material||brass||Cast iron with copper plating|
|Flange standard||National standard||Non-standard|
|main material||The plug body is QT500-7 ductile iron with a tensile strength of 500MPa. The internal parts are brass and 304 stainless steel.||The bolt body is ordinary cast iron, with a tensile strength of 200MPa,|
|The internal parts are cast iron|
|Sealing method||Lift-up seal, three-stage opening||Down-pressure seal, one-stage opening|
|The sealing performance is stable.||If the seal is not tight, it is easy to damage and leak water.|
|Regulating performance||The pressure regulating plate is opened in three stages to realize the function of pressure reducing, stabilizing and regulating.||Without any pressure regulating function|
|Anti-collision performance||When hit by an external force, the anti-collision disk will automatically fall off, and the piston will automatically seal the water source without water leakage. The repair time is short and the repair is convenient, and the repair cost is reduced by 80%.||There is no anti-collision function, crushing rupture, difficult maintenance, long time and high maintenance cost. The water source cannot be closed, and a lot of water is lost.|
|Antifreeze function||Coaxial linkage, closed discharge synchronization structure, the remaining water in the ground plug is automatically emptied, the emptying time is less than 30 seconds, without any heat preservation, and it is not frozen at minus 50°C.||The glass ball of the plastic valve body leaks water and is easily broken under high pressure. The drain port is less than 3 mm, which is easy to block and fail, and the failure rate of the spring is very high.|
|Anti-theft function||Dedicated magnetic encryption switch anti-theft water||Ordinary disk, high failure rate|
|Service life||10 years||3-5 years|
