Hope it works for you!!

The spacing requirements for indoor fire hydrants are: 1. The spacing of fire hydrants should not be greater than 30 meters for buildings arranged according to the two plumbing water columns of 2 fire water guns; 2. The fire hydrant is arranged according to a full water column of 1 fire water gun, and the spacing of the fire hydrant should not be greater than 50 meters. The specific requirements for the setting of indoor fire hydrants are: 1. In order to facilitate maintenance and management, the layout of water guns, faucet belts and indoor fire hydrants of the same specification should be used in the same building, and the required number of water column strands should reach any corner of the room at the same time, and there can be no dead ends; 2. Fire hydrants should be distributed in all floors of the building, arranged in a bright, often accessible and convenient place, generally arranged in the fire-resistant stairwell, corridor, hall and workshop entrances and exits.

The height of the central device of the fire hydrant valve is meters from the floor surface; 3. Fire hydrants and fire risers are uniformly surface-mounted in general buildings, in the case of higher requirements for buildings and narrow ground due to the impact of surface-mounted protrusions, the concealed installation method is adopted, and the bottom of the fire riser is provided with a ball valve, the valve is often opened, and there should be obvious opening and closing signs, and the water hose set in the fire box should be placed neatly at ordinary times, so as to quickly use it when extinguishing the fire.

The hydrant is between 0 and 120 meters away from the norm.

If the fire hydrant is installed indoors, the spacing is generally less than 30 meters, and if it is more than 30 meters, it cannot meet the needs of two water jets at the same time. If fire hydrants are installed outdoors, they should generally not be more than 120 meters apart. The specific spacing that needs to be maintained needs to be reasonably arranged according to the actual installation environment.

Specification requirements and precautions for the installation of fire hydrants.

1. Generally, indoor fire hydrants should be located in a place that is obviously easy to access. The height of the bolt mouth from the ground should be downwards or at an angle of 90° to the wall where the fire hydrant is arranged.

2. The indoor fire hydrant of the cold storage should be located in the hall or stairwell at room temperature. Avoid fire hydrants from bursting and becoming unusable due to low temperatures.

3. The spacing of indoor fire hydrants should be determined by calculation. The spacing of high-rise industrial buildings, elevated warehouses, Class A and B workshops, and indoor fire hydrants should not exceed 30m. The spacing of indoor fire hydrants in other single-storey and multi-storey buildings should not exceed 50m.

Fire hydrants, water cannons and hoses of uniform specifications should be used in the same building. The length of each hose should not exceed 25m.

4. For buildings with indoor fire hydrants, if they have flat roofs, fire hydrants for testing and inspection should be set on the flat roofs.

Precautions for installing fire hydrants:

1. Indoor fire hydrants should be located in a place that is obviously easy to access. The height of the bolt mouth from the ground should be downwards or at an angle of 90° to the wall where the fire hydrant is arranged. The indoor fire hydrant of the cold storage should be located in the hall or stairwell at room temperature.

2. The spacing of indoor fire hydrants should be determined by calculation. The spacing of indoor fire hydrants in high-rise industrial buildings, elevated warehouses, Class A and B workshops should not exceed 30m. The spacing of indoor fire hydrants in other single-storey and multi-storey buildings should not exceed 50m.

Fire hydrants, water cannons and hoses of uniform specifications should be used in the same building. The length of each hose should not exceed 25m.

3. For buildings with indoor fire hydrants, if they have flat roofs, fire hydrants for testing and inspection should be set up on the flat roofs.

4. High-rise industrial buildings and other buildings whose water tanks cannot meet the water pressure requirements of fire hydrants at the most unfavorable points should be set up at each indoor fire hydrant to directly start the fire pump, and the mountain should be closed with protection facilities. <>

The calculation formula of the installation distance of the outdoor fire hydrant is the design of the protection radius of the outdoor fire hydrant and the maximum arrangement spacing 1, the protection radius of the outdoor fire hydrant. The protection radius of outdoor low-pressure fire hydrant water supply is generally considered according to the fire truck series 9 hoses, the water gunner on the fire ground has a 10m mobile hose, if the hose is laid along the ground coefficient Xiang noise stall according to the calculation, then the fire truck water supply distance is (9 20-10). Therefore, the protection radius of outdoor low-pressure fire hydrants is 150m.

The protection radius of outdoor high-pressure fire hydrant water supply is considered according to the series of 6 water belts, and the protection radius is (6 20-10) in the same calculation. Therefore, the protection radius of outdoor high-pressure fire hydrants is the maximum arrangement spacing of outdoor fire hydrants. The principle of the spacing arrangement of outdoor fire hydrants is to ensure that any part of the urban area is between the protection radius of the two fire hydrants.

According to the construction of urban roads, the maximum layout spacing of municipal fire hydrants X = R2-(L Z)2, R is the maximum protection radius of fire hydrants, and L is the distance between the center lines of the streets, which is about 160m according to urban planning requirements. It is calculated that the spacing of outdoor low-pressure fire hydrants is x=127m, and the spacing of outdoor high-pressure fire hydrants is x=60m.

Considering the needs of water supply at the fire site, the maximum spacing of outdoor low-pressure fire hydrants should not be greater than 120m, and the maximum spacing of high-pressure fire hydrants should not be greater than 60m. Construction and installation 1), construction and installation should be in accordance with the "Building Water Supply Drainage and Heating Engineering Construction Quality Acceptance Code" GB50242-2002 relevant standards, you can refer to the National Building Standard Design Atlas 01S201 "Outdoor Fire Hydrant Installation". 2) The system must be tested for hydraulic pressure, and the test pressure is times the working pressure, but it shall not be less than the position of the outdoor fire hydrant The sign should be obvious, and the position of the bolt mouth should be convenient for operation.

When the bolt is wall-type, if the design does not require, the central installation height of the inlet and outlet water plug mouth should be from the ground, and the above should be equipped with anti-falling object strike measures. 4), the installation dimensions of the outdoor fire hydrant and the fire pump adapter should meet the design requirements, the allowable deviation of the installation height of the bolt mouth is the distance between the top outlet of the underground fire hydrant and the bottom surface of the fire manhole cover shall not be greater than 400mm, and there should be enough operating space in the well, and a ladder should be provided. In cold areas, the well should be protected from freezing.

6) Before the completion of the fire pipeline, the pipeline must be flushed.

Summary. Hello, glad to answer for you. The distance left at the door of the indoor fire hydrant: the minimum spacing of the indoor fire hydrant is not specified in the specification, referring to the minimum distance between the building evacuation doors of 5 meters, we generally set the minimum distance between the indoor fire hydrants at 5 meters when designing.

The layout interval should not be greater than 120m, the distance from the edge of the road should not exceed 2m, the distance from the outer wall of the building should not be less than 5m, the distance from the external wall of high-rise buildings should not be greater than 40m, and the distance from the external wall of general buildings should not be greater than 150m. The sedan shouted.

Number of outdoor fire hydrants in the building. The number of outdoor fire hydrants should be determined according to the comprehensive calculation of its protection radius, flow rate and outdoor fire fighting volume, and each flow rate should be 10-15L s. For high-rise buildings, municipal fire hydrants within 40m can be included in the number of outdoor fire hydrants in the building; For multi-storey buildings, the municipal fire hydrant protection radius is within 150m, if the fire water consumption is not more than 15L s, the building can not be equipped with an outdoor fire hydrant.

We know that no matter what is installed, it must be in accordance with the requirements, so as to achieve the effect you want, fire hydrants believe that everyone will be familiar with it, so be sure to figure out its spacing when installing. Let's introduce to you what are the requirements for the spacing of outdoor fire hydrants.

1. If the width is more than 60 meters along the road, it is suitable to set up fire hydrants on both sides of the road, and it should be close to the intersection.

3. The spacing of outdoor fire hydrants should generally not exceed 120 meters.

4. The number of fire hydrants should be determined according to the water consumption of fire fighting, and each water consumption should be calculated according to 10 15L s.

What to pay attention to when installing fire pipes.

It is still necessary to be prepared when constructing, and you must choose the right construction materials.

1. First of all, it is necessary to ask for fire pipes, in fact, generally speaking, galvanized carbon steel pipes will be selected. This kind of pipe fittings are uniformly galvanized inside and outside, and there is no corrosion, so it can be said that the use of this pipe makes the life of the device longer.

2. Secondly, you should choose the right pipe. For fire hydrants, under normal circumstances, carbon steel pipes will be used, this kind of pipes, can not be bent when used, and are prone to unevenness, users can choose their own situation to determine, must meet the requirements.

3. The next step is the selection of alarm valves and control valves, as well as indicators and other components, and the accessories must be kept complete, and all kinds of accessories must meet the relevant standards.

4. It is necessary to choose a suitable sprinkler head, and its specifications and types must meet the design requirements, and its appearance must be regular and complete.

5. The fire hydrant box can not ignore a place, it must be kept square, and the accessories in the box must be complete, flexible to use, and have the relevant characteristics such as certificates.

Summary: What are the relevant contents of the requirements for the spacing of outdoor fire hydrants, and the spacing of outdoor fire hydrants generally cannot exceed 120 meters. If you want to know more about related knowledge, you can consult Qijia.com.

The spacing of indoor fire hydrants is as follows:

It should not be greater than 30m: high-rise factories (warehouses), high-bay warehouses and Class A and B workshops; High-rise civil buildings. should not be greater than 50m: the spacing of indoor fire hydrants in other single-storey and multi-storey buildings; Podium of high-rise civil buildings.

Indoor fire hydrant is the indoor pipe network to supply water to the fire site, with a valve interface, for factories, warehouses, high-rise buildings, public buildings and ships and other indoor fixed fire protection facilities, usually installed in the fire hydrant box, and fire hose and water gun and other equipment for use.
