D. Open the valve counterclockwise and spray it out. Note: The electric fire must be determined to cut off the power.
Second, the type of fire hydrant
a. Indoor fire hydrant
Indoor fire hydrants are indoor pipe networks supplying water to fire sites, with interfaces for valves, fixed fire-fighting facilities for factories, warehouses, high-rise buildings, public buildings, and ships, usually installed in fire hydrant boxes, and fire hoses and guns. Supporting the use of. Decompression type fire hydrants are one of them.
b. outdoor fire hydrant
The outdoor fire hydrants are water supply facilities installed on the fire-fighting water supply pipe network outside the building, mainly for the fire-fighting vehicles to take water from the municipal water supply pipe network or the outdoor fire-fighting water supply pipe network to extinguish the fire, and can also directly connect the water hose and the water gun to extinguish the fire. Therefore, the outdoor fire hydrant system is also one of the important firefighting facilities for fighting fires.
c. Rotating fire hydrants
The rotating fire hydrant is an indoor fire hydrant in which the plug body can rotate 360Â° horizontally relative to the base connected to the water inlet pipe. It has the characteristics of relative rotation of the plug body and the base, so it can be installed in the ultra-thin case, making it possible to thin the case. When the fire hydrant is not in use, the outlet of the plug body can be rotated to a state parallel to the wall, and the box door can be closed. When the fire hydrant is used, the outlet of the plug body can be turned out perpendicular to the wall, and the water can be connected to the wall. operating.
d. Underground fire hydrant
Underground fire hydrant is an outdoor ground fire water supply facility. It is used for fire-fighting vehicles or directly connected with hoses and water guns for fire extinguishing. It is a special facility for outdoor fire-fighting water supply. Installed underground, it does not affect the appearance of the city and the city. It consists of body, elbow, valve seat, valve disc, drain valve, stem and interface. Underground fire hydrants are essential fire-fighting and water supply devices in cities, factories, mines, power stations, warehouses, docks, houses and public places. Especially in urban areas and areas where there are few rivers, they need to be installed. Product structure, reliable performance, easy to use.
e. Ground fire hydrant
The ground fire hydrant is an outdoor fire-fighting water supply facility. It is used for fire-fighting vehicles or directly connected with hoses and water guns for fire extinguishing. It is a special facility for outdoor fire-fighting water supply. The upper part is exposed on the ground, the sign is obvious, and it is easy to use. It consists of body, elbow, valve seat, valve disc, drain valve, stem and interface. The fire hydrant on the ground is an urban essential fire-fighting equipment, especially in areas with less urban areas and rivers. It needs to be installed to ensure the need for fireflood. All densely populated areas such as factories, mines, warehouses, yards, freight yards, high-rise buildings, and public places should be installed with conditions.
f. Double valve double exit fire hydrant
An indoor fire hydrant is a valved interface that is installed in a building's fire pipe network to provide water to the fire site. It is an indoor fixed fire-fighting equipment such as factories, warehouses, high-rise buildings, and ships. It is used to save fires in buildings. It is usually installed in fire hydrant boxes and used with fire hoses and water guns.
