    The fire pump adapter is the interface for the fire brigade to use the fire truck to draw water from the outdoor water source and supply water to the indoor pipe network. Its function is: when the building encounters a large fire and fire-fighting water is insufficient, the water can be sent to the indoor fire-fighting water supply pipe network through it to supplement the shortage of fire-fighting water; When the indoor fire pump fails, the fire truck takes water from the outdoor fire hydrant and sends the water to the indoor fire water supply network through it; When the indoor fire-fighting water is insufficient, and the fire pump is working normally, the water can be sent to the fire-fighting pool located in the building through it; When the pressure of the indoor fire pump is insufficient, the water can be sent to the indoor fire water supply network through it.

    There are three types of water pump adapters: above-ground, underground, and wall-based. Above-ground water pump adapters, which are generally used, are obviously easy to use; Underground water pump adapter, suitable for cold areas and when there are aesthetic requirements, installed under the road surface, do not occupy space; Wall-mounted water pump adapters are rarely used, and should be installed on solid walls when used.

    Design requirements. Low-rise buildings with a building height of no more than 24m, when the building volume exceeds 1000m

    1. Fire pump adapter: When the indoor fire pump fails or the indoor fire water supply is insufficient, the fire truck will be sent to the indoor fire water supply website through the pump adapter for water extraction and pressurization

    2. Setting requirements:

    1. The number of fire pump adapters should be calculated according to each 10-15L s.

    2 When a temporary high-pressure fire water supply system supplies water to multiple buildings, the fire pump adapter should be installed near each building.

    3 The water supply range of the fire pump adapter should be determined according to the water supply flow and pressure of the local fire truck.

    4. When the fire water supply is supplied to the vertical zone, the fire pump adapter should be set up separately within the water supply pressure range of the fire truck.

    5. When the height of the building exceeds the water supply height of the fire truck, the suction and pressurization interface of the hand pump or mobile pump relay water supply should be set up in the equipment floor and other convenient operation places.

    6. The water pump adapter should be located in a place that is convenient for fire trucks to be used outdoors, and the distance from the outdoor fire hydrant or fire pool should not be less than 15m and should not be greater than 40m.

    7. The installation height of the wall-type water pump adapter should be based on the ground, and the net distance from the door and window holes on the wall should not be less than 2m, and it should not be installed under the glass curtain wall.

    8 A permanent marking nameplate shall be set at the water pump adapter, and shall indicate the water supply system, water supply range and rated pressure.

    This question does not meet the setting requirement (a) of the pump combiner

    a.High-rise civil buildings and factories and warehouses with more than 5 floors, high-rise industrial buildings, residential buildings with indoor fire water supply pipes and other civil buildings with more than 9 floors should be equipped with water pump adapters;

    b.The location of the pump adapter should be within 15m-40m from the outdoor fire hydrant or fire pool;

    c.The flow rate of each pump adapter section is calculated according to 10-15L s, and the number of pump adapters is calculated and determined according to the water consumption of indoor fire hydrants;

    d.A check valve should be set on the pipe section connected to the pump adapter, and a gate valve and a drain valve for maintenance should also be provided.

    The water pump adapter is the equipment used with the water pump in the fire fighting, when a fire occurs, the water pump of the fire truck can be quickly and conveniently connected with the anti-counterfeiting equipment in the building through the interface of the coupling Shanqin, and send water to pressurize, so that the indoor fire-fighting equipment can get sufficient pressure water source, in order to extinguish the fire on different floors, and effectively solve the situation that after the fire occurs in the building, the fire truck is difficult to extinguish or the fire-fighting equipment in the room cannot be extinguished because of the insufficient pressure water source.

    According to the installation type, the fire pump adapter can be divided into: above-ground type, underground type, wall type and multi-purpose type.

    The nominal diameter of the connector outlet can be divided into two types: 100mm and 150mm.

    The nominal pressure of the adapter can be divided into and so on.

    The connector connection method can be divided into flange type and threaded type.
