Ground fire hydrant foam fire hydrant industrial chemical fire hydrant

Description :

　　1、 The installation design of fire hydrants should consider installing them in the intersection area of the street. They should be placed in a prominent location that does not affect pedestrians and vehicles, while also considering maintenance and convenient daily drainage and drainage. Like walking along the sidewalk. Beside the rainwater drainage outlet, on the side of the pedestrian walkway and trees. Some ground type fire hydrants, due to their initial installation and subsequent changes in road elevation, bury or block the water outlet of the hydrant with soil, resulting in changes in water quality inside the hydrant chamber and rusting of the screw rod, which affects the water quality of the pipe network and the service life of the hydrant. According to Article 7.2.2 of the "High Standard", "The number of outdoor fire hydrants should be determined by calculation based on water consumption." Practice has shown that when designing outdoor fire hydrants, the number of water pump couplings must be considered, with one outdoor fire hydrant corresponding to one water pump coupling. Some designers consider water pump couplings and add the number of indoor fire hydrants calculated based on outdoor fire water consumption to the required number of outdoor fire hydrants for the water pump couplings to design outdoor fire hydrants. The number of hydrants installed is too many, which is unrealistic and unreasonable. According to Article 7.3.6 of the High Standards, the number of outdoor fire hydrants shall be determined by calculation based on the water consumption of outdoor fire hydrants specified in Article 7.2.2 of the High Standards. The water consumption of each fire hydrant shall be between 10 L/s and 15 L/s. ”For the convenience of fire trucks, fire hydrants should be evenly arranged along the fire lane. If they can be placed on the side of the road near high-rise civil buildings, it can avoid the problem of fire trucks crushing water hoses and causing them to burst during firefighting. For the convenience of fire trucks directly taking water from the fire hydrant, the distance between the fire hydrant and the roadside should not be greater than 2 meters; there should be an operating area for firefighters around the fire hydrant, so the distance from the building exterior wall should not be less than 5 meters. At the same time, for ease of use, it is stipulated that the distance between the fire hydrant and the protected building should not exceed 40 meters.

　　2、 Installation design of underground fire hydrants. The design and installation of underground fire hydrants are located in underground well rooms, so the height and plane position of the fire hydrant outlet are crucial for the convenience of water intake. Considering the water intake connection from the fire department, the height of the outlet from the ground should be controlled at around 30cm, and for maintenance and use convenience, the plane position of the outlet should be adjacent to the wellhead. If the fire hydrant well is very deep and the connecting riser of the fire hydrant is too long, the riser should be fixed inside the well to ensure safety during use.

　　3、 For the design of outdoor fire hydrants near super high-rise buildings, consideration should be given to the distance between the hydrant and the pump adapter of the super high-rise building, so that in the event of a fire in the building, the fire department can draw water and add pump connections within a short distance.
