What Types Of Fire Hydrants Are There?Aug 03, 2019
1. Indoor fire hydrant
The indoor fire hydrant is an indoor pipe network that supplies water to the fire field. 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-regulated 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 carry out fire fighting. 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 in which the plug body can be rotated 360 degrees 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 outlet can be rotated parallel to 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 underground 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 underground, does not affect the city appearance, traffic. It consists of valve 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 reasonable structure, reliable performance and convenient use. When using underground fire hydrants, there should be obvious signs. Underground fire hydrants are more common in cold areas.
5. 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 valve 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 fewer rivers to ensure the need for fire water supply. The densely populated areas such as mines, warehouses, docks, freight yards, high-rise buildings, and public places should be installed.
6. Double port double valve fire hydrant
One type of indoor fire hydrant, “Code for Fire Protection Design of High-rise Civil Buildings” stipulates that: In the following cases, when two fire-fighting risers are difficult, a vertical pipe may be provided, but a double-valve double-outlet type fire hydrant must be used. 1, 18-story and 18-story residential units; 2 18-story and 18-story, no more than 8 households per floor, with a building area of no more than 650 m2.
7. Outdoor direct buried telescopic fire hydrant
The outdoor direct-buried telescopic fire hydrant is a fire hydrant with the characteristics that the fire hydrant shrinks below the ground and is pulled out of the ground during use. Compared with the ground type, the collision is avoided and the anti-freezing effect is good; compared with the underground type, it is not required. The underground well room is built and connected above the ground, which is convenient for work. And the interface direction of the outdoor direct-buried telescopic fire hydrant can be rotated 360° according to the water receiving needs, which is more convenient to use.
