Fire detection tube type extinguishing device

      The fire detection tube automatic fire extinguishing device does not need any power supply, no special smoke, temperature detector, no complex equipment and pipelines, using its own pressure storage, relying on a pressurized fire detection tube and a set of fire detection bottle group can quickly, accurately and effectively detect and extinguish the fire source.

Design of fire detection tube type temperature sensing self-starting fire extinguishing device.

1. Protective area

      The fire tube type temperature sensing self-starting fire extinguishing device takes the relatively closed and small volume equipment in the space with small volume or the place with large space as the protection area.

     When the direct temperature sensing self-starting fire extinguishing device is used, the volume of the protection area should not be greater than 10m3; When the indirect fire tube temperature sensing self-starting fire extinguishing device is used, the volume of the protection area should not be greater than 100m 3.

2. System design

     The direct fire pipe extinguishing device should be designed by volume method. The indirect fire pipe extinguishing device can be designed by volume method or area method. The design dosage of fire extinguishing agent for fire detection tube type temperature sensing self-starting fire extinguishing device should be calculated according to the following formula:

M=Q×V

Type:

M------- Design dosage of fire extinguishing agent for fire tube type temperature sensing self-starting fire extinguishing device (kg)

Q------- Minimum amount of extinguishing agent required per unit volume (kg/m3)

V------- Volume of protection area (m3)

3. The actual amount of carbon dioxide extinguishing agent should be calculated according to the following formula:

G =P×N

Where: G----- Actual dosage of fire extinguishing agent (kg)

P----- Filling of fire extinguishing agent in storage container of a single fire detection tube type automatic fire detection and extinguishing device (kg)

N----- Number of storage containers for fire detection tube type automatic fire detection and extinguishing device

Carbon dioxide fire extinguishing agent should meet the current national standard GB4066 provisions.

4.The protection area protected by the fire pipe extinguishing device

      The protection area or protected object protected by a set of fire detection tube fire extinguishing device should not be more than 6; The fire detection tube fire extinguishing device set in one protection area should not exceed 4 sets, and should be able to start at the same time, and the action response time difference should not be greater than 2s.

5. Explore the layout of the fire tube

     The location of the fire detection tube should not exceed 1 meter from the protected place and the distance between the fire detection tube. See the following diagram for fire detection tube layout requirements.
