Characteristics of pressure type foam fire extinguisher Compounded foam fire extinguishing device

Description :

　　The PHYM series pressure type proportional mixing device (i.e. horizontal foam fire extinguisher) produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. is composed of foam liquid storage tank, pressure type proportional mixer, safety valve, control valve and some auxiliary parts. When the fire pressure water flows through the equipment, the proportional mixer divides its proportion, and a small part of the water flows into the interlayer of the foam liquid storage tank. The replaced foam liquid is mixed with the fire water of the other main pipes to form a certain proportion of foam liquid mixture, which is delivered to the foam generating equipment. PHYM series pressure type proportional mixing device is applicable to all kinds of foam liquid with mixing ratio of 3% and 6%.

　　The pressure type foam proportioning device is used to store foam extinguishing agent and replace foam extinguishing agent through the pressure type foam proportioner using the water supply of the pump set, and mix with the water supply in a certain proportion to form foam mixture.

　　The pressure type foam proportional mixing device is a common foam extinguishing equipment at present. The pressure type foam proportioning device is easy to install, use and maintain, with excellent built-in corrosion resistance, relatively economical cost, stable and reliable performance, and is especially suitable for medium and small flow foam fire extinguishing systems. Mainly applicable to places where flammable or combustible liquids are produced, stored, transported, and used; Fire hazard areas such as petrochemical enterprises, oil depots, loading and unloading docks, ship docks, oil extraction platforms, aircraft hangars, and automobile garages.

　　Product Features

　　1. The foam mixing ratio is accurate and reliable, the sprayed foam liquid has strong penetration ability and high fire extinguishing efficiency.

　　2. The unused foam liquid can be used continuously to save foam liquid and reduce costs.

　　3. It has a wide scope of application, and can be used for high, medium and low expansion foam extinguishing agents.

　　Installation of the device

　　The direction of pressure water flow during installation should be consistent with the direction indicated by the arrow on the proportional mixer on the device. Pressure gauges, one-way valves, control valves, pipeline filters, etc. should be installed before the proportioning mixer; The foam tank shall be fixed with the ground foundation.

　　Filling method of foam concentrate

　　Close all valves, open two exhaust valves, fill 1/3 to 1/2 of the tank water between the tank and the tank through the water inlet pipe and the drain port, then open the liquid filling port, insert an inch rubber pipe from the liquid filling port to the tank bottom, inject foam extinguishing agent into the tank through the crossover pipe, open the drain valve after water is discharged from the exhaust port, and drain water at a flow similar to the flow of foam liquid filling until the foam liquid is fully filled. After filling is completed, close the filling port and drainage valve, open the inlet valve, and slowly fill the space between the tank and the tank with water until water flows out from the exhaust port. Close the exhaust valve and inlet valve, and then rinse the scattered fire extinguishing agent outside the device with clean water.
