The fire foam tank consists of a foam pressure tank with a capsule and a PHY pressure proportioner using the Venturi principle. When the water in the system pipe network passes through the proportional mixer pressure relief orifice plate, there will be a pressure difference before and after the orifice plate. Part of the high-pressure water enters the tank through the foam tank inlet pipe, squeezes the capsule, and the foaming agent in the capsule is squeezed through the foam tank pipe to the proportional mixer and mixed with water at low pressure to form a foam mixture, and the formed foam mixture is output to The production equipment is mixed with air to produce foam to extinguish the fire. Next, let's take a look at the foam extinguishing agent manufacturer to introduce the fire foam tank.

1. foam fire extinguishing agent manufacturer introduces the product composition of fire foam tank

Valve and pressure gauge are installed on each pipeline. The capsule is installed in the tank body, and its inner cavity is independent from the tank body cavity.

2. foam fire extinguishing agent manufacturers introduce the fire extinguishing principle of fire foam tank

It is used to store the foam fire extinguishing agent, and through the action of the pressure proportional mixer, the foam fire extinguishing agent is stored in the fire water supply replacement device, and mixed with the water supply device in a certain proportion to form a foam mixture. According to the structure of the storage tank, it can be divided into: horizontal proportional mixing device and vertical proportional mixing device; according to the number of batching mixers, it can be divided into: single batching mixer and multi-batching mixer (2 or 4 sets).

1. The mixing ratio of the foam tank is very stable, accurate and reliable, and can provide high-quality foam mixture.

2. The pressure drop loss of the foam tank is small, the energy of the sprayed foam extinguishing agent is large, and the penetrating ability is strong. Can quickly put out the fire.

3, save foam liquid, reduce the cost of fire fighting. Since the capsule of the foam tank divides the foam liquid from the water, the foam liquid can not be used up at one time and can be used again next time, and the mixing accuracy is stable and reliable.

3. foam fire extinguishing agent manufacturers introduced the scope of application of fire foam tanks

Both high, medium and low expansion foam fire extinguishing agents can be used. The foam proportioning unit of the foam automatic fire extinguishing system can use both foam spray heads and spray heads. It is widely used in oil storage tank area, chemical plant, aircraft hangar, oil field, oil power plant, boiler room, underground garage, dangerous goods warehouse, chemical warehouse and other places.

Water-soluble water-forming foam fire extinguishing agent has the performance of general water-forming foam fire extinguishing agent that can quickly extinguish oil fires, and can make the fire extinguishing agent form a layer of gel film on the surface of polar flammable liquids to protect the fire extinguishing foam from damage.

Fire foam consists of three parts: foam concentrate, water and air. The concentrate (proportionally) is mixed with water. A foam solution was formed. The foam solution is mixed with air (inhaled) to produce foam, which is very liquid and flows quickly to the surface of the liquid. The foam itself is many small, stable bubbles filled with air. Less dense than oil, gasoline or water.
