What are the purposes of these fire-fighting equipment?
Fire fighting equipment is the most direct fire extinguishing tool at the fire scene, and how to correctly master and use fire fighting equipment will play an irreplaceable role in reducing casualties and property losses in fire. What are the purposes of these fire-fighting equipment?
1. Fire hydrant box
In case of fire alarm, press the spring lock on the door according to the opening and closing mode of the box door, and the pin will automatically exit. After opening the box door, take out the water gun, pull the water hose tray, pull out the water hose, connect the water hose interface with the fire hydrant interface, press the fire hydrant alarm button in the box, unscrew the indoor fire hydrant handwheel in the open direction, and then spray water to extinguish the fire.
2. Fire hose
The fire hose is a hose used for water conveyance at the fire scene. Fire hose can be divided into lined fire hose and unlined fire hose according to materials. The unlined water hose has low pressure, large resistance, easy water leakage, easy mildew and corrosion, and short service life. It is suitable for fire site laying in buildings.
3. Water hose buckle
Water hose buckle: used to connect water hoses, fire engines, fire hydrants and water guns. So as to deliver water and foam mixture for fire extinguishing. The utility model is composed of a body, a seal ring seat, a rubber seal ring, a retainer ring and other components. The seal ring seat is provided with a groove for water binding. The utility model has the advantages of good sealing, fast connection and labor saving, and is not easy to fall off. Pipe thread interface: installed at the water inlet end of the water gun, and the internal thread fixed interface is installed at the fire hydrant. Water outlet of fire pump; They are composed of body and sealing ring, one end is pipe thread, and the other end is internal thread. They are used to connect water hoses.
4. Fire water gun
The fire water gun is a water jetting tool for fire fighting, which can spray dense and substantial water when connected with the water hose. It has the advantages of long range and large water volume. It is composed of main parts such as pipe tooth interface, gun body and nozzle. DC switch water gun is composed of DC water gun, ball valve switch and other components, which can control the water flow through the switch.
5. Indoor fire hydrant
The utility model relates to a fixed fire fighting tool. It is mainly used to control combustibles, isolate combustibles and eliminate ignition sources. Use mode of indoor fire hydrant:

6. Outdoor fire hydrant
The utility model relates to a fixed fire connection equipment installed outdoors, which includes outdoor ground type fire hydrant, outdoor underground type fire hydrant, and outdoor directly buried retractable type fire hydrant.
The ground type connects water on the ground, which is easy to operate, but easy to be collided and frozen; The underground anti freezing effect is good, but a large underground well chamber needs to be built, and firefighters need to collect water in the well when using, which is inconvenient to operate. The outdoor directly buried retractable fire hydrant is usually pressed back below the ground and pulled out of the ground for work. Compared with the ground type, it can avoid collision and has good antifreeze effect; It is easier to operate than the underground type, and the direct buried installation is simpler.
7. Water tank
The water tank is the storage tank connected with the fire pipeline, which is mainly used for the water supply equipment in the fire to better prevent the spread and extinguishment of the fire.
