The fire pool on the door of the indoor fire hydrant system, the fire water supply is not applied, and the fire hydrant box is composed.

Kiss Glad to answer for you: Indoor fire hydrant system door fire pool, fire water supply is not applied, what fire hydrant box and other components Answer: Kiss Composition of indoor fire hydrant system:

Water guns, hoses, fire hydrants, fire pipes, fire pools, high water tanks, water pump adapters, booster water pumps. 1. Outside the equipment floor where there are no combustibles, the building with indoor fire hydrants should be equipped with fire hydrants on each floor. 2. An internal fire hydrant should be set up in the front room of the fire elevator.

3. The indoor fire hydrant should be located in a place that is obviously easy to access, the height of the bolt mouth from the ground is meters, and the direction of the water outlet should be downward or at an angle of 90 ° with the wall where the fire hydrant is set. 4. The indoor fire hydrant of the cold storage should be located in the hall or stairwell at room temperature. 5. Fire hydrants, water guns and water bags of uniform specifications should be used in the same building for ease of use.

6. Permanent signs should be set up at the indoor fire hydrants and valves of the building. 7. Outdoor fire hydrants should be set along the road. When the width of Qingxun road is greater than 60 meters, it is advisable to set up small tiger bolts on both sides of the road, and it is advisable to be close to the back of the crossroads.

8. The spacing of outdoor fire hydrants should not be greater than 120 meters.

Dear, hello, the use of sprinkler fire hydrant is as follows: 1. Open the fire hydrant door and press the internal pump alarm button (the button is to start the fire pump and alarm). 2. One person picks up the gun head and water hose and runs to the ** point.

3. The other person connects the other end of the hose to the aluminum mouth of the bolt. 4. Open the valve counterclockwise and spray out the water. Note:

Electricity** to make sure to cut off the power supply. The fire protection system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguishing system, automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system, etc. The fire hydrant set is generally composed of a fire box + fire hose + water gun + buckle + bolt + clip, etc., the fire hydrant is mainly used by fire trucks to take water from the municipal water supply pipe network or outdoor fire protection to pat the water pipe network to extinguish the fire, and can also be directly connected to the hose and water gun to extinguish the fire.

Hello, I am glad to answer for you, the principle of outdoor fire hydrant water is as follows: Outdoor fire hydrant is provided with automatic water outlet, and the water outlet is laid with pebbles for water seepage, the principle is that after the connecting gate valve of the outdoor fire hydrant is closed, the pressure in the hydrant is lost, and the water outlet will be automatically opened, and the water in the water in the empty hydrant is emptied, so as to ensure that the fire hydrant will not be frozen. How the outdoor fire hydrant system works:

1) Atmospheric high-pressure fire-fighting water supply system: Maintain sufficient pressure and fire-fighting water consumption in the pipe network of the atmospheric high-pressure fire-fighting water supply system. When a fire breaks out, the personnel on the scene can take out the hose and water gun from the fire hydrant box set up nearby, connect the hose with the fire hydrant mouth, connect the water gun, and open the valve of the fire hydrant. Directly out of the water to extinguish the fire.

2) Temporary high-pressure fire water supply systemIn the temporary high-pressure fire water supply system, the system is equipped with a fire pump, and the pressure in the pipe network is usually low. When the fire breaks out, the personnel on the scene can take out the hose and water gun from the fire hydrant box set up nearby, connect the hose with the fire hydrant mouth, connect the water gun, open the valve of the fire hydrant, and notify the water pump room to start the fire pump, so that the pressure in the pipe network can meet the water pressure requirements of the high-pressure water supply system, so that the fire hydrant can be put into use. (3) The pressure in the pipe network of the low-pressure fire water supply system of the low-pressure fire water supply system is low, when the fire breaks out, the firefighters open the nearest outdoor fire hydrant, connect the fire truck with the outdoor fire hydrant, and add water from the outdoor pipe network to the fire truck, and then use the fire truck to directly pressurize the fire extinguisher, or the fire truck pressurizes the water supply to the indoor pipe network through the water pump adapter.

The working principle of the indoor fire hydrant water supply system: The working principle of the indoor fire hydrant water supply system is related to the water supply mode of the system. It is usually for the fire water supply system of the building, and the temporary high-pressure fire water supply system is used.

In the temporary high-pressure fire water supply system, the system is equipped with a fire pump and a high-level fire water tank. When the fire breaks out, the personnel on the scene can open the fire hydrant box, connect the hose with the fire hydrant mouth, open the valve of the fire hydrant, and press the start button in the fire hydrant box, so that the fire hydrant can be put into use. The button in the hydrant box directly starts the hydrant pump and alarms the fire control center.

In the initial stage of water supply, the initial water supply is supplied by a high fire water tank (storing the amount of fire fighting water in lomin) due to the activation of the fire hydrant pump for a certain period of time. For the start of the fire hydrant pump, it can also be started by the fire pump site and the fire control center, and the fire hydrant pump shall not automatically stop the pump once it is started, and the pump can only be manually controlled by the site.

1. The water in the sprinkler system and fire hydrant generally comes from the fire pool.

2. The pipes of these systems are usually filled with water, after a fire, the sprinkler is turned on, or the fire hydrant is opened, and the water flows out, but the follow-up water lacks sufficient power, and the fire pump must be turned on to pressurize, so that the water in the pool can be continuously replenished to the pipeline, which can form fire extinguishing water.

3. The pump is usually closed, but it should be set in an automatic state (that is, once the system loses water, the fire pump will be automatically turned on for water supply), if it is set in a manual state, the pump room should be on duty, once the system is out of water, the attendant should immediately judge whether there is a fire alarm, and manually start the fire pump water supply.

4. Always check whether the water in the fire pool is at the specified water level.

It is connected to the main water pipe and is kept at all times.
