What should I do if the sprinkler head is damaged? Urgent!

Broken sprinklers are reported to the flow indicator and pressure switch, but the regulator pump does not need to be turned off when the signal butterfly valve is closed. The pressure stabilizing pump usually replenishes the pressurized water to the fire pipeline, and the pipeline connection is cut off after the corresponding signal butterfly valve is closed, so it is not necessary to close the pressurized water.

After the pressure switch alarms, the electric fire pump will be started in linkage, so after confirming that it is not a real fire, it is the electric fire pump that needs to be turned off.

If you want to study the materials, since the fire protection industry belongs to the industry of national compulsory testing, it is recommended that you study more books on national norms. Including: fire alarm system design specifications and construction acceptance specifications, automatic sprinkler system design specifications and construction acceptance specifications, gas fire extinguishing system design and construction acceptance specifications, etc., but also familiar with the basic principles of the fire protection law.

In this way, we can do a good job of firefighting.

The damage of the sprinkler head reports the water flow indicator and pressure switch, and the pressure regulator pump needs to be turned off, otherwise the sprinkler head will be replenished with water on the water side, but it will be busy.

If the sprinkler head breaks, you will need to turn off the (or fire zone) water flow indicator on this level. If there is no water, the heavy pipe will come in and it will be fine, and then go to the end of the waterproof handle, but now it is estimated that it is already a vast ocean

Sprinkler head blasting, sprinkler fire extinguishing - water flow through the water flow indicator action electrical signal sent to the alarm controller - because the sprinkler head continues to sprinkle water alarm valve completely rise, the electrical signal is sent to the alarm controller - the water flow will enter the delay through the wet alarm valve, in 30-60s full of the delayer - flow to the hydraulic alarm bell to send an alarm - at the same time the pressure switch starts - send an electrical signal input alarm control box to send an alarm signal, and then start the fire pump. In order to prevent damage or maintenance needs, each partition will have a maintenance valve and end discharge, when the sprinkler sprinkles water in time to close the maintenance valve in this area, it will prevent the future associated alarm action, so there is no need to close the pressure stabilizer pump (the pressure stabilizer pump is the fire pipe network to supplement the pressure water, a regional maintenance, can the fire pump be stopped?) It is a reason) on-site treatment to find the end of the water to drain the water, and at the same time use the fire hose to divert the flow, and sandbags and other items can be used to prevent the ground water flow area from being too large and entering the dangerous area.

Hehe, you really can't learn in this class, unless you have done it in the installation team for a while!

The sprinkler head was found to be bursting. The on-duty personnel of the engineering department and the security department confirmed on the spot.

Is there a fire?

In the absence of fire:

1) Close the regional water supply valve.

2) Open the drain valve at the end of the system, (3) Replace the sprinkler head.

4) Restore the sprinkler system's water supply system.

In case of fire:

1) Immediately notify the fire control room, and take fire extinguishers and hydrants to extinguish the fire, and the personnel on duty in the fire control room immediately start the hotel fire emergency plan.

2) After extinguishing the fire, comprehensively inspect the on-site equipment, make records, take pictures, and protect the scene.

3) Replace and repair damaged equipment.

4) If the fire cannot be extinguished, the manager on duty shall immediately notify the Public Security Fire Bureau 119.

5) The personnel on duty in the fire control room immediately turn on the fire broadcast to prevent the public from entering and evacuate the public in the hotel. Turn on the alarm bell.

6) Assist the public security fire to extinguish the fire.

7) Accident report submitted by the manager of the security department.

The sprinkler head is accidentally broken, and the treatment process is as follows:

1. Close the signal valve of the area to block the water **, 2. Open the valve of the water test device at the end of the area to achieve controlled drainage 3, clean and control the wastewater sprayed by the ruptured sprinkler to reduce the loss, 4, replace the sprinkler head or install the plug at zero o'clock for repair.

It is best to do 1 and 2 of the above at the same time, in no particular order.

When the regional signal valve fails, it is advisable to close the water supply valve of the wet report valve in the area and discharge water from the wet report valve.
