What are the components of Fire Hydrant System?
A fire hydrant is a conspicuous connection point built in specific areas to allow firemen to access a water supply. Fire hydrants with a link to a water supply network must be installed in all buildings, parking lots, roadside areas, mines, and industrial zones, among other places.
They’re made to supply firefighters with the water they need to attack and extinguish a fire quickly. Underground fire hydrants were utilized until the 18th century. Above-ground pillar-type fire hydrants became popular and widely employed from the 19th century onwards. A fire hydrant system is just a pipe with a valve that allows water to flow from a water main to extinguish a fire.
Fire Hydrant Purpose and Applications
The primary function of fire hydrants is to deliver water to the fire suppression system. They can, however, be used for a variety of secondary applications, including:
Flushing the Lines
Fire hydrants can be used to flush main distribution system lines because of their high flow capabilities and ease of operation.
System for Testing
Fire hydrants can be used to assess the hydraulic capacity of the distribution system.
Common applications
Fire hydrants are also commonly used for commercial construction work, sewer cleaning, roadway construction, and street cleaning, among other things.
Fire Hydrant Types
There are two kinds of fire hydrants: wet hydrants and dry hydrants.
Wet Hydrant
Wet hydrants are commonly utilized in areas where freezing is not an issue. The water in the main supplies the hydrant close to the surface in these sorts of fire hydrant systems. As a result, it is sensitive to freezing in cold temperatures.
Dry Hydrant
A dry hydrant system stores water beneath the earth. The temperature of the Earth is frequently greater than the temperature of the frigid surroundings in cold locations. As a result, this design eliminates the danger of freezing. When using the dry hydrant system, firefighters open a valve on top of the hydrant and insert their hoses into it. This causes the drain valve within the hydrant to open. This permits water to enter, which the firemen use to extinguish the fire.
