Pressure type foam fire extinguisher manufacturer proportional mixing fire extinguishing equipment fire foam extinguishing device

Description :

　　The PHYM series pressure type proportional mixing device produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. is referred to as horizontal foam tank. It is produced in strict accordance with national standards, with advanced technology, mature technology, complete models and stable performance. The PHYM series pressure type proportional mixing device is applicable to all kinds of foam liquid with a mixing ratio of 3% or 6%.

　　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.

　　The pressure type proportional mixing device is mainly composed of a foam liquid pressure tank with and a PHY type pressure type proportional mixer made by using the Venturi principle. When the water flow in the system pipe network passes through the pressure reducing orifice plate of the proportional mixer, 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.

　　The product features are as follows:

　　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.
