Heptafluoropropane foam fire extinguishing equipment-Xinxiang Jinsheng Fire Protection Technology Co., Ltd

Product Introduction

PQF series heptafluoropropane foam fire extinguishing equipment generates foam mixture through foam proportioning device. foam mixture forms heptafluoropropane foam mixture after passing through heptafluoropropane proportioning device, and heptafluoropropane foam mixture generates heptafluoropropane foam through heptafluoropropane foam generation device. Heptafluoropropane foam has the dual fire extinguishing effect of chemical inhibition and air isolation, and is suitable for extinguishing low boiling point flammable liquid fires with boiling point lower than 45 ℃ and mole percentage of C5 and below components not less than 30%. The system equipment was inspected in accordance with XF 1288-2016 Heptafluoropropane foam Fire Extinguishing System, and has a type inspection report issued by Tianjin Fire Research Institute of the Emergency Management Department.

Advantages and Features

Using heptafluoropropane fire extinguishing agent for foaming, the foam produced is uniform and dense, and its covering, isolation and fire resistance are significantly better than air foam;
The generated heptafluoropropane foam has the dual extinguishing effect of isolation coverage and chemical suppression, which can effectively and quickly extinguish fires.

1. Foam proportional mixing device

The foam proportional mixing device uses pressure proportional mixing device, balance proportional mixing device, mechanical pump proportional mixing device, etc. The foam proportional mixing device is a product that meets the requirements of GB20031-2005 standard.

2. Sevofluoropropane proportional mixing device

The SEvofluoropropane proportional mixing device proportionally mixes the sevofluoropropane agent in the sevofluoropropane storage device with the foam mixture to form the sevofluoropropane foam mixture. It mainly consists of SEvofluoropropane proportional mixer, control valve, pressure reducing valve, filter and so on.

3. Heptafluoropropane supply unit

Heptafluoropropane supply device shall meet the requirements of GB29572-2010 standard.

4. Sevofluoropropane foam producer

Sevofluoropropane foam generator can use sevofluoropropane and foam mixture to produce uniform dense foam. It has the dual effect of covering air isolation and chemical inhibition, which greatly improves the fire extinguishing efficiency. Sevofluoropropane generator is made of stainless steel.

5. Control system

Hfc-propane foam fire extinguishing device adopts automatic control system, which can realize remote one-click start and on-site manual start system.

Working principle

After receiving the fire signal, the central control room starts the fire pump and sends the start signal to the HFC-propane foam fire extinguishing system control cabinet. The control cabinet starts the foam proportional mixing device, HFC-propane supply device and HFC-propane foam proportional mixing device in sequence according to the set instructions. After the fire fighting pressure water passes through the foam proportional mixing device to form the foam mixture, the foam mixture is transported to the HFC-propane proportional mixing device, where the foam mixture of the HFC-propane proportional mixing device is mixed with HFC-propane to form HFC-propane foam mixture, and the HFC-propane foam mixture is generated by the HFC-propane foam generator to extinguish the fire.
