Installation requirements:
1. The installation of water pump adapter shall be carried out in the order of interface, body, connecting pipe, check valve, safety valve, exhaust pipe and control valve. The installation direction of the check valve should enable the fire water to enter the system from the fire pump adapter, and the installation of the integral fire pump adapter should be carried out according to its installation instructions.
2. The water pump adapter should be located in an outdoor place convenient for fire engines to pass, and the distance from the outdoor fire hydrant or fire pool should not be less than 15m and not more than 40m.
3. The permanent fixed sign of the fire pump adapter should be able to identify its corresponding fire water supply system or water extinguishing system, and there should be a zoning sign when there is zoning.
4. The underground fire pump adapter shall be marked with "fire pump adapter", and a permanent fixed sign shall be set nearby to indicate its position.
5. The installation of the wall fire pump adapter should meet the design requirements. When the design has no requirements, the installation height should be 0.7m from the ground; The clear distance from doors, windows, holes and holes on the wall should not be less than 2.0m, and should not be installed below the glass curtain wall.
6. The installation of the underground fire pump adapter should make the distance from the water inlet to the bottom of the manhole cover not more than 0.4m and not less than the radius of the manhole cover.
7. There should be no obstacles between the hydrant water pump adapter and the fire escape that hinder the pressurized water supply of the fire truck.
8. Waterproof and drainage measures should be taken for the masonry of underground fire pump adapter well.
Extended data:
According to the provisions of the "High Code", each partition within the water supply pressure range of fire engines needs to be equipped with a separate water pump adapter. Previously, it was thought that some fire engines with a building height of more than 50 m could not be rescued, so it may be considered not to set up a water pump adapter.
However, with the update and development of fire fighting technology and equipment, many cities have been equipped with high-power fire engines, and the water supply for fire fighting has far exceeded 50m, so 50m should no longer be used as the boundary for setting up water pump adapters.
