Indoor Fire Hydrant System Valve Set Basic Principle

             A fixed firefighting tool. The main function is to control combustible materials, isolate the combustion-supporting material and eliminate the ignition source. Fire system includes outdoor hydrant system, indoor hydrant system, fire extinguisher system, and some will have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire probing system, mist system, etc.Fire Hydrant Valves

             Fire hydrant, officially called the fire hydrant, a fixed type of firefighting facilities, the main role is to control combustible materials, isolate the combustion, eliminate the fire source. Indoor fire hydrant and outdoor fire hydrant. Fire system includes outdoor hydrant system, indoor hydrant system, fire extinguisher system, and some will have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire probing system, mist system, etc. Fire hydrant is mainly used to fire extinguishing water from municipal water supply pipe network or outdoor fire-fighting water supply pipe network, and it can also directly connect water belt and fire-gun outlet. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities. The general valve uses the clear rod flange gate valve.Fire Hydrant Valves

               Indoor hydrant system valve Set Basic principles: 1, indoor fire water piping should be divided into several separate valves. 2, the horizontal annular pipe network, for the single storey construction, the garage, the overhaul stop use fire hydrant should not surpass 5. 3, for multi-storey civil buildings and other plant (warehouse), should ensure that the maintenance of the pipe closed when the vertical pipe does not exceed 1, but the set of vertical pipe more than 3 root, can be closed 2. 4, for high-rise civil building, should ensure that the maintenance of the pipe closed when the vertical pipe does not exceed 1, but the set of vertical tube more than 4 root, you can close the adjacent 2. 5, the valve shall be set up at the upper and lower ends of each riser and the dry pipe of the water supply; 6, the horizontal annular pipe network should be installed according to the fire zoning valve, and the number of fire hydrant in the same layer is not more than 5 (not including the two ends of the valve with a closed connection of the hydrant); 7, in any case, the valve should be closed to each fireproof zone at least a hydrants can be used normally.Fire Hydrant Valves
