Introduction of Foam Fire Extinguishing Device of Fire Alarm Controller

Foam fire extinguishing equipment is an important part of the foam fire extinguishing system. The main products of foam fire extinguishing equipment are: foam proportion mixer (ring pump foam proportion mixer, pressure proportion mixer, negative pressure proportion mixer, balanced proportion mixer), foam generator (low multiple air foam generator, low multiple air foam generator, medium multiple air foam generator, high multiple air foam generator, foam nozzle, foam nozzle), non-pipeline foam fire extinguishing device (normal pressure box fire extinguishing device, outdoor foam fire hydrant, foam spray fire extinguishing device, foam spray fire extinguishing device, semi-fixed foam fire extinguishing device), other foam fire extinguishing equipment (kitchen fire extinguishing cylinder cabinet, closed foam-water sprinkler system, foam-water dual-purpose cannon, foam-water dual-purpose cannon, tunnel-specific foam spray control valve group, large space detector), pressure storage tank (fixed pressure storage tank, mobile pressure storage tank, fixed negative pressure storage tank, mobile negative pressure storage tank).

1. Foam proportion mixer

1. Ring pump foam proportion mixer

PH series foam proportion mixer is installed on the water pump and matched with the water pump. According to the requirements of the foam mixed liquid amount of the foam spraying equipment, the foam liquid is sucked in proportion and sent to the water inlet pipe of the water pump to mix with water to form a foam mixed liquid fire fighting equipment

Mixing ratio: 6%~7%;

Inlet pressure (MPa): 0.6~1.4 (pressure at the water outlet of the water pump);

Outlet back pressure (MPa): <0.03 (pressure at the water inlet of the water pump);

2. Pressure proportion mixer

1. The mixing ratio of the mixed liquid of the device is adjustable, and the mixing ratio is stable and not affected by pressure changes. 2. The resistance drop value of the pressure proportion mixer is small.

3. The water source can be directly taken from the pressure water pipe network or fire truck.

4. Since the pressure water and foam liquid are separated by the diaphragm bag in the tank, the foam liquid is stored in a closed manner, not easy to corrupt and deteriorate, and is suitable for spraying detection at any time.

5. The foam system of this device is always ready for fire fighting.

6. This device is suitable for high, medium and low multiple foam fire extinguishing systems.

7. This device can be equipped with multi-proportion mixers with different mixing ratios in the same tank. 8. The tank of this device can be made of carbon steel plate, stainless steel plate or stainless steel-carbon steel composite steel plate. 3. Negative pressure proportion mixer

PHF series negative pressure proportion mixer can automatically absorb foam liquid of different proportions. It is a supporting equipment for mobile or local application high multiple foam fire extinguishing system. When pressure passes through the equipment, water and foam liquid can be mixed in a ratio of 3% or 6%, and supplied to high multiple foam generator to produce foam to extinguish Class A or Class B fires.
