What measures should be taken for fire sprinkler spraying

If the fire sprinkler is sprayed by mistake, you are not afraid of anything.

The regulations on the spraying of the fire sprinkler include: the shape of the upper sprinkler is the parabolic shape, and 80 100% of the total water volume is sprayed downward, and at the same time, a part of the spray is sprayed to the ceiling, which is suitable for installation in places with more moving objects and is prone to impact, such as warehouses, and can also be concealed in the roof of the room ceiling mezzanine to protect the boron of the ceiling with more flammable materials.

Legal basis: Fire Protection Law of the People's Republic of China

Article 8 Local people at all levels shall include fire protection planning, including fire safety layout, fire stations, fire water supply, fire communications, fire truck access, fire fighting equipment, etc., into urban and rural planning, and be responsible for organizing the implementation.

If the urban and rural fire safety layout does not meet the fire safety requirements, it shall be adjusted and improved; If the public fire-fighting facilities and fire-fighting equipment are insufficient or do not meet the actual needs, they shall be added, reconstructed, configured or technologically transformed.

Article 9 The fire protection design and construction of construction projects must conform to the national technical standards for fire protection in engineering construction. Construction, design, construction, engineering supervision and other units shall be responsible for the fire protection design and construction quality of construction projects in accordance with the law.

Article 52 The local people's departments at all levels shall implement the responsibility system for fire protection work, and supervise and inspect the performance of fire safety duties by the relevant departments of the people's governments at the same level.

The relevant departments of the local people's ** at or above the county level shall, according to the characteristics of the system, carry out targeted fire safety inspections, and promptly supervise and rectify fire hazards.

The accidental explosion of the fire sprinkler head shall immediately close the regional water supply valve and open the drain valve at the end of the system.

Fire sprinkler is used in the fire sprinkler system, when a fire occurs, the water is sprinkled out through the sprinkler splash tray to extinguish the fire, which is currently divided into drooping sprinkler head, vertical sprinkler head, ordinary sprinkler head, side wall type sprinkler head, etc.

The spray lid is welded to the thread with fusible metal, and the melting point is 57 degrees. Therefore, in the event of a fire, the lid falls off when the temperature rises, and when the temperature rises to 68 degrees Celsius (a typical sprinkler head), the glass tube bursts and water jets out.

Close the signal valve under the wet alarm valve, replace the false explosion nozzle with a substitute nozzle, and restore all valves to working condition after replacement.

First turn off the valve in the area where you burst the sprinkler, and then open the drain valve in that area, most of which are installed in the bathroom.

If you can find the copper plug that bursts the nozzle, it is best to use it to block it first (it can be blocked in the state of low pressure) and replace the new nozzle when the drain valve is almost leaked, and it is best to open the closed valve, and the system will return to normal.

Immediately close the branch pipe valve, open the end of the water discharge device to discharge water, empty the water in the faulty pipe as soon as possible, replace the damaged sprinkler head, open the branch valve after completion, observe whether the replaced sprinkler head has water leakage, no water leakage to complete the maintenance work, if it is a large pipe network, do exhaust work.

The height of the space on the ceiling is not more than 800mm, and the lower sprinkler can be used directly.

In accordance with the relevant regulations. It's okay to do that.
