Fire hydrant use method, steps

How to use fire hydrants? Fire hydrants are the most common of all fire equipment. The concrete can be divided into indoor fire hydrant, outdoor fire hydrant, rotary fire hydrant, underground fire hydrant, ground fire hydrant, double port double valve fire hydrant, outdoor direct burial telescopic fire hydrant. The following Xiaji network Xiaobian share the steps and precautions for using the fire hydrant.

First, fire hydrant for medium

Indoor fire hydrant is an important part of the fire water system. It is installed in the indoor fire box. Generally, the nominal diameter (mm): DN50, DN65, nominal working pressure 1.6MPa, strength test pressure 2.4MPa, suitable medium: cleaning Water, foam mixture. Usually indoor fire hydrants can be divided into ordinary type, decompression regulator type, rotary type, etc. The fire extinguishing method of the fire hydrant is connected to the bolt by the artificial water belt. In addition, there is a fire hydrant button in the fire hydrant box. Press this button to start the fire pump remotely. Replenish the fire hydrant.

Second, the use of fire hydrant steps

(1) Open the fire hydrant door and press the internal fire alarm button (the button is for alarm and start the fire pump).

(2) One person connects the tip of the gun and the end of the hose to the fire.

(3) Another person connects the other end of the hose to the valve port of the fire hydrant.

(4) Rotate all the valves counterclockwise to open the valve and spray the water.

(5) After the fire is extinguished, the water belt should be washed and dried, placed in the box according to the coiling or folding method, and the water gun is caught in the gun holder, and the box door is closed.

Fire hydrant use precautions

1. Do not stack any items on the side of the fire box;

2. Do not use when not in a fire;

3. After the fire is extinguished, the water belt is dried and restored.

4, always pay attention to whether the indoor fire hydrant has lost its use function, because the fire hydrant is not used regularly, so there is no failure to know;

5. Some fire hydrants set up in the community to see if they are practical, because there is no water in the fire hydrant water pipes in some residential corridors, but it plays a hypothetical role;

6. When using the fire hydrant, notice that the water belt is not twisted, which will affect the water flow, and the fire extinguishing method is from near to far;

7. If it is caused by a fire such as gasoline or alcohol, it is impossible to directly spray water onto the liquid surface, so that the fire is more fierce;

8. If the appliance is on fire, be sure to cut off the power before extinguishing the fire.

Third, the type of fire hydrant and its application

1. Indoor fire hydrant

The indoor fire hydrant is an indoor pipe network that supplies water to the fire site. The interface with valves is an indoor fixed fire-fighting facility for factories, warehouses, high-rise buildings, public buildings and ships. It is usually installed in fire hydrant boxes, and fire hoses and water guns. Supporting the use of. A decompression type fire hydrant is one of them.

2, outdoor fire hydrant

The outdoor fire hydrant is a water supply facility installed on the fire water supply pipe network outside the building. It is mainly used for the fire truck to take water from the municipal water supply network or the outdoor fire water supply network to extinguish the fire. It can also directly connect the water belt and the water gun to extinguish the fire. Therefore, the outdoor fire hydrant system is also one of the important fire protection facilities for fire fighting.

3, rotating fire hydrant

The rotating fire hydrant is an indoor fire hydrant whose body can be rotated 360o horizontally with respect to the base connected to the water inlet pipe. It has the characteristics of relative rotation between the plug and the base, so it can be installed in the ultra-thin box, making it possible to thin the box. When the fire hydrant is not used, the plug water outlet can be rotated to be parallel with the wall to close the door; when in use, the plug outlet can be screwed out perpendicular to the wall to connect the water hose. operating.

4, underground fire hydrant

The underground fire hydrant is an outdoor ground fire water supply facility. It is used for water supply to fire trucks or directly connected to water hoses and water guns for fire fighting. It is a special facility for outdoor fire water supply. Installed in the ground, does not affect the city, the city. It consists of components such as body, elbow, valve seat, valve disc, drain valve, valve stem and interface. Underground fire hydrants are essential fire-fighting water supply devices for cities, factories, mines, power stations, warehouses, terminals, residential and public places. In particular, areas with less urban areas and fewer rivers need to be installed. The product has the same structure, reliable performance and convenient use.

5, the ground fire hydrant

The ground fire hydrant is an outdoor ground fire water supply facility. It is used for water supply to fire trucks or directly connected to water hoses and water guns for fire fighting. It is a special facility for outdoor fire water supply. Its upper part is exposed to the ground, the sign is obvious, and it is easy to use. It consists of components such as body, elbow, valve seat, valve disc, drain valve, valve stem and interface. Above-ground fire hydrants are a must-have fire-fighting equipment in the city, especially in areas with less urban areas and less rivers, to ensure fire and flood. All densely populated areas such as factories, mines, warehouses, yards, freight yards, high-rise buildings, and public places should be installed.

6, double valve double outlet fire hydrant

The indoor fire hydrant is a valved interface that is installed on the fire pipe network inside the building to provide water to the fire. It is an indoor fixed fire-fighting equipment such as factories, warehouses, high-rise buildings, and ships. It is used to extinguish fires in buildings. It is usually installed in fire hydrant boxes and used in conjunction with fire hoses and water guns.

The above is about the use of fire hydrants and precautions, etc., usually in the residential aisle and some shopping malls and corridors have installed striking fire hydrants, in order to make it work in the fire, regular maintenance should be regularly checked whether the fire hydrant is intact Whether there is rust phenomenon; the fire hydrant valve should be filled with lubricating oil; regularly check whether the reel, water gun, water hose is damaged, whether the valve and reel are flexible, whether the fire hydrant box door is damaged, etc. If the problem is found, it should be replaced in time. ,repair.
