Industrial fire-fighting equipment manufacturer vertical foam fire extinguisher pressure type proportioning device

Description :

　　Water is a commonly used fire extinguishing agent, with convenient application, abundant sources, and low price. Therefore, it has been widely used in fire scenes.

　　Water cannot extinguish fires caused by the following substances and equipment: fires caused by alkali metals, fires caused by carbonization, hydrogenation, and yellowing; Sulfuric acid, nitric acid, and hydrochloric acid should not be extinguished with strong water; Light and insoluble in flammable liquids (excluding oil and heavy oil); Molten iron and steel; When there is a fire in high-voltage electrical equipment without good grounding equipment or without cutting off the current.

　　Foam is a group of bubbles with small volume and surrounded by liquid on the surface, which only fights fires caused by flammable liquid and gas. The foam used in China includes chemical foam and air mechanical foam (air foam for short).

　　The main principle of foam fire extinguishing is that foam is lighter than flammable and combustible liquids, and it covers the liquid surface on fire to prevent liquid vapor from entering the combustion area, prevent air from contacting the burning surface, prevent heat from conduction to the liquid surface, and absorb certain heat, thus stopping combustion.

　　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 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 PHYM (L) series products produced by Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. have the following characteristics compared to other types of products:

　　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.
