Fixed foam fire extinguishing equipment Horizontal foam fire extinguisher Pressure proportional foam fire extinguishing device

Description :

　　The pressure type foam proportioning device can be divided into horizontal, vertical, single proportioning mixer, double proportioning mixer, etc. according to the structure type, and users can choose according to the actual configuration needs and the location of the installation space.

　　The pressure type foam proportional mixing device mainly consists of tank body, proportional mixing body, water inlet pipe, liquid outlet pipe, drain valve, drain valve, safety valve and pressure gauge. Each pipeline is equipped with a valve, and a pressure gauge is installed on the inlet pipeline, which is installed inside the tank. Its inner cavity and tank cavity are independent of each other.

　　Force type foam proportioning device is mainly composed of foam liquid pressure storage tank and PHY type pressure proportioner made by 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.

　　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.

　　After the installation and acceptance of the device, there should be full-time or part-time firefighters to inspect, maintain and upkeep the device:

　　1. Regularly inspect the storage tank and proportioner every month to ensure that there are no leaks, rust, mechanical damage, etc;

　　2. Test the foam liquid in the tank every half a year to ensure that the chemical composition and performance of foam liquid meet the standard requirements;

　　3. Open the ball valve of the level gauge to observe the level of foam. After observation, close the ball valve of the level gauge in time.
