Fire fighting water belt is a kind of curly carry, can pump the pressure water discharge to the fire fighting scene of the pipeline. The correct use and maintenance of the water belt has an important role in ensuring the success of fire fighting, so usually pay attention to maintenance, always in good condition.
Pick up the fire belt, throw the water belt, the water belt connector aligned with the hydrant, clockwise direction a turn connected, pick up the water gun head aligned with the connector also clockwise rotation connected, open the hydrant water, water gun aligned with the fire source, a left a right or shaking fire.
When using the water belt is strictly forbidden to zigzag to prevent local fractures, do not drag on the ground at will. In the fire to prevent flames and radiation heat, pay special attention not to make the water belt and high temperature contact, do not make the water belt stained with oil, acid and alkali substances, once stained, to be washed and dried in a timely manner. Climb high when laying water belt with water belt hook, through the road when laying water belt should be padded with water belt bridge guard, to prevent the water belt and hard objects with angles contact. When breaking buildings, do not throw boards, steel and other hard and heavy items to the water belt. Small holes in the water belt should be wrapped in a timely manner with a package of this wrapping, so as not to expand the small hole, and make a mark, and timely repair after use. Winter fires need to suspend the water supply, in order to prevent the water belt ice, should maintain a small amount of water through. When the water belt icing, pay attention to the volume received to prevent damage. After use should be cleaned and dried in time.
Hydrant water belt use method: water belt should be rolled vertical on the water belt frame, at least twice a year and exchange the folded edge once; usually there should be a person responsible for the management, and often check whether the joint deformation, there is no damage. Once found damaged, should be promptly repaired. Fire hose with, to empty the water belt in the leftover water, and hang in the ventilation sun dry, after the volume good into the fire box.
There are many kinds of fire extinguishing water guns, according to the different performance and use, commonly used water guns are mainly DC water guns, blooming DC water guns, atomized water guns, multi-purpose water guns and special-purpose force guns and other kinds.
DC water gun can be divided into DC blooming water gun and DC switch water gun two kinds. DC blossom water gun, rotate the front of the water gun to turn the circle, can spray DC water flow and umbrella blossom water flow separately and simultaneously. Among them, the umbrella flowering water flow plays a role in self-defense protection, DC water flow is mainly used for fire extinguishing. Water gun code for QZK, nozzle made of plastic, other major parts are aluminum alloy.
When operating DC water gun shooting water, the operator is vulnerable to the impact of reaction force, so, such as changing the direction of water injection, should be operated slowly, the best equipped to overcome the reaction force elbow-shaped interface. When using the switch water gun, the switch action should be slow, otherwise, it is easy to produce water hammer, causing harm to the water belt.
There are more types of atomized water gun, according to its function, can be divided into single-function water gun and multi-function water gun. According to its structure, can be divided into three major types of rotating centrifugal, impact and tangential waterway type. In these three types, the common is tangential waterway type. The structure of the atomization principle is: water under the action of water pressure, from the center of the water gun at high speed from the tangential waterway spray, due to the role of centrifugal force, the formation of high-speed rotational movement in the spray body, the nozzle sprayed by the formation of a rotating cone of water mist and air flow collision, mixing, so as to form a good atomization of water droplets.
When using spray water gun to put out electrical equipment fires, a certain safety distance should be maintained; when using spray water gun to put out oil fires, pay attention to the hazards of radiation heat to the operator.
Fire hydrant is a fixed fire-fighting water supply equipment connected to a fire source for fire engines or other mobile fire-fighting equipment to get water. According to the installation location, it can be divided into two kinds of indoor fire hydrants and outdoor fire hydrants.
