　　Fixed foam fire extinguishing system

　　PHYML24/10 vertical pressure proportional mixing device

　　【working principle】

　　The pressure type foam proportioning device is mainly composed of a foam liquid pressure storage tank and a PHY type pressure type proportioner made by using the Venturi principle. When the water flow in the system pipe network passes through the pressure reducing orifice plate of the proportioner, a pressure difference will be formed before and after the orifice plate. Part of the water (3% or 6%) at the high pressure enters the foam tank through the water inlet pipe of the foam tank and is squeezed. The foam liquid in the tank is squeezed through the liquid outlet pipe of the foam tank to the low pressure of the proportioner and mixed with water to form foam mixture. The formed foam mixture is output to the foam production equipment and mixed with air to produce foam.

　　【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 and usage instructions

　　【 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.

　　Introduction

　　Mobile foam truck and PY mobile (truck) foam fire extinguishing device are portable and flexible wheeled fire extinguishing equipment. It adopts PHF pipeline (negative pressure) proportional mixer, which can form low, medium and high expansion foam fire extinguishing system with foam gun and foam generator. When the pressure water passes through the mixer, the water is mixed with foam liquid in a certain proportion, and foam is sprayed through the foam gun and foam generator to extinguish the fire. It is composed of cart, atmospheric foam tank, negative pressure proportioner, spraying equipment, water hose, safety valve, control valve and some auxiliary parts.

　　Application scenarios

　　Mobile foam fire extinguishing device is quick, simple and reliable. Used to extinguish Class A, B, and C non water soluble liquid fires. Widely used in municipal residential areas, factories and mines, oil depots, chemical departments, heat treatment workshops, gas stations and other places.

　　working principle

　　When the mobile foam fire extinguishing device extinguishes the fire, the pipe tooth interfaces at both ends of the pipeline proportional mixer are connected with the fire hose, and the pressure water source is connected. When there is water with a pressure of not less than 0.6MPa flowing through the nozzle of the proportional mixer at a high speed, due to the diffusion effect of the transverse movement of the jet particles, a vacuum (negative pressure) is formed in the room of the proportional mixer, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under the pressure of the atmosphere, mixes with the pressure water, and finally reaches a certain proportion of the mixed liquid, and sprays foam through the foam gun and the foam generator to extinguish the fire.
