　　Pressure type foam extinguishing device foam proportional mixing tank fire foam tank manufacturer

　　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 inlet pipe of the foam tank and is squeezed. The foam liquid in the tank is squeezed through the outlet pipe of the foam tank to the lower pressure than the mixer and mixed with water to form a foam mixture. The foam mixture formed is output to the foam generation equipment (medium, low and high expansion foam generators, foam guns, foam monitors, etc.) and mixed with air to produce foam for extinguishing.

　　The PHYM series pressure type proportioning device consists of a pressure tank, capsule, proportioning mixer, safety valve, exhaust valve, pressure gauge, one-way valve, various control valves and pipelines. The pressure water is supplied by the pump, and the foam liquid is replaced in a certain proportion and mixed with the pressure water to form foam liquid. Since * * * separates foam liquid from water, foam liquid is not used up at one time, and can be used again next time with stable and reliable mixing precision. The device is applicable to a wide range of flow and pressure, with small pressure loss, and has been widely used in various high, medium and low expansion foam fire extinguishing systems. According to the structural form, it can be divided into two types: horizontal and vertical.

　　Working principle When the pressure water flows through the proportional mixer, part of the pressure water (3%~6%) enters the foam liquid storage tank through the branch pipe
