Fire fighting equipment must be equipped in high-rise buildings. Although it is usually overlooked, when a fire occurs, its fire extinguishing and fire prevention functions are fully reflected. So, what are the main uses of fire fighting equipment? What methods can be used to distinguish the authenticity of fire fighting equipment? Today, let's take a look at the fire extinguisher Testing Equipment of Zonsky Instrument.
Zonsky Instrument Fire Extinguisher Filling Equipment wants to tell everyone fire engineering company that fire fighting equipment in fire engineering design refers to the equipment used for fire extinguishing, fire prevention and fire accidents. Its scope of use is very wide, and its specific main uses are reflected in the following aspects:
1. Fire hydrant box
When there is a fire alarm, according to the opening method of the box door, press the spring lock on the door, and the pin will automatically withdraw. After opening the door, take down the water gun and turn the hose reel, pull out the hose, and connect the hose coupling with the fire hydrant interface at the same time, press the fire hydrant alarm button inside the box, and unscrew the indoor fire hydrant handwheel in the opening direction , that is, sprinkler fire can be carried out.
2. Fire hose
The fire water gun is a water jet tool for fire extinguishing. When it is connected with a hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. It consists of main components such as the pipe tooth interface, the gun body and the nozzle. The DC switch water gun is composed of a DC water gun with a ball valve switch and other components to control the water flow through the switch.
3. Hose buckle
Hose connection buckle: used for connection between hoses, fire trucks, fire hydrants, and water guns, so as to transport water and foam mixture for fire extinguishing. It consists of a body, a sealing ring seat, a rubber sealing ring, a retaining ring and other parts. There is a groove on the sealing ring seat for tying the water belt. It has the characteristics of good sealing, fast and labor-saving connection, and not easy to fall off.
Pipe tooth interface: Installed on the water inlet end of the water gun, and the internal thread fixed interface is installed on the fire hydrant. At the water outlet of the fire pump, they are all composed of a body and a sealing ring, one end is a pipe thread, and the other end is an inner buckle. They are both used to attach hoses.
4. Fire hose
The fire hose is a hose used for water delivery at the fire scene. According to the material, the fire hose can be divided into two types: lined fire hose and unlined fire hose. The unlined hose has low pressure, high resistance, easy to leak, mildew, and short life, and is suitable for laying in fire places in buildings. The lining hose can withstand high pressure, wear resistance, mildew resistance, not easy to leak, low resistance, durable, can also be bent and folded at will, moved at will, easy to use, suitable for laying on external fire sites.
What Zonsky Instrument fire extinguisher Testing Equipment wants to tell you is that the authenticity of fire-fighting equipment can be distinguished in these ways:
Appearance recognition:
The appearance marks of counterfeit and shoddy products are often blurred and rough, with incomplete content and not durable. For example, the trademark casting on the valve body of the counterfeit fire hydrant is unclear, there is no specification and model mark on the interface, and the fire hose is not marked with the word "fire protection", which is deliberately confused. The surface and packaging of regular fire protection products should have clear and durable marks, including product marks and quality inspection marks (certificate of conformity). The product logo shall include the name and address of the manufacturer, product name, product model (specification), main technical coefficients, product trademark, production date and product number, and the implementation standard code. Quality inspection marks should include inspectors and qualified marks.
Identify by material
In addition, the physical surface of fire protection products should use non-combustible materials or flame-retardant materials according to the standard requirements, but the use of flammable or flammable materials can be used as a basis for judging that it is a counterfeit and shoddy product, such as fire emergency lamps. The surface of the fire hydrant box should be made of flame retardant or non-combustible materials as required instead of plexiglass and other combustible materials.
The above situation will not occur with the fire hose inspection equipment produced by Zonsky Instruments. The fire hose testing equipment list includes fire hose wear test machine, fire hose extension torsion test apparatus, fire hose low temperature properties test equipment, fire hose physical and mechanical properties test instrument, fire hose bending test machine, fire hose water belt water pressure comprehensive testing equipment and so on.
