　　Key points for selection

　　1) Previously, underground fire hydrants were used in cold regions, while above ground fire hydrants were preferred in non cold regions. If conditions permit, anti-collision fire hydrants can be used for above ground fire hydrants. When using underground fire hydrants, there should be clear markings. Now, with the emergence of outdoor direct buried telescopic fire hydrants, their functions are better than above ground ones in terms of collision avoidance and anti freezing effect; Compared with the underground type, there is no need to build an underground well, direct burial installation is simpler, and operation on the ground is more convenient and fast. The interface of the outdoor buried telescopic fire hydrant can rotate 360 °.

　　2) Outdoor above ground fire hydrants should have one diameter of 150mm or 100mm and two outlets with a diameter of 65mm. Outdoor underground fire hydrants should have one nozzle with a diameter of 100 and one with a diameter of 65mm.

　　3) The protection radius of outdoor fire hydrants should not exceed 150m, and the spacing should not exceed 120m.

　　4) Outdoor fire hydrants should not be more than 2 meters away from the roadside and should not be less than 5 meters away from the exterior wall of the house.

　　5) When the building is within a 150m radius of municipal fire hydrant protection and the fire water consumption does not exceed 15L/s, outdoor fire hydrants may not be installed.

　　6) Outdoor fire hydrants should be evenly arranged around high-rise buildings and should not be concentrated on one side of the building.

　　7) The distance between the outdoor fire hydrant of civil air defense engineering and the entrance of civil air defense engineering should not be less than 5m.

　　8) The outdoor fire hydrant in the parking lot should be installed along the perimeter of the parking lot, and the distance from the nearest row of cars should not be less than 7m, and the distance from the gas station or garage should not be less than 15m.

　　9) Outdoor fire hydrants should be installed in locations that are convenient for fire trucks to use.

　　Foam fire hydrant is one of the important devices in the foam fire extinguishing system, especially suitable for the production, storage and use of large areas of flammable liquids and flammable liquids with fire hazards. Foam fire hydrant is mainly composed of flange, cylinder, ball valve, internal connection, fire pipe thread and end cover.

　　Features of foam fire hydrant: quick opening and closing, light weight, which is a new creative improvement and enhancement based on the traditional fire hydrant. With the valve plate seal, you can rely on the pressure seal of the medium itself. The higher the pressure, the better the seal. Especially suitable for foam fire lines, a good lubrication chamber is designed: the main components are made of highly corrosion-resistant materials, and the main components are located in the oil tank, which can always be fully lubricated. Long term use and maintenance will not rust or get stuck. Its foam mixture switch adopts stainless steel ball valve to ensure free opening.

　　Foam fire hydrants are suitable for petrochemical enterprises, refineries, oil storage tank farms, aircraft hangars and other important places. It is a special fire-fighting equipment installed on the foam mixture pipe to supply foam mixture to the foam spraying equipment.
