Fire Hydrant System

Fire hydrant is a fixed fire-fighting facility. Its main function is to control combustible materials, isolate combustion-supporting materials, and eliminate sources of ignition. Divided into indoor fire hydrants and outdoor fire hydrants. Classified as indoor fire hydrant, outdoor fire hydrant, above ground fire hydrant, underground fire hydrant, dry fire hydrant, wet fire hydrant. By country, commonly use British fire hydrant, Russian fire hydrant and French fire hydrant.

Operation:

1. Use a wrench to open the water bag connection switch of the underground fire hydrant.

2. Connect the fire hose.

3. Use a wrench to open the outlet valve switch of the underground fire hydrant.

4. Connect the hose mouth and the water nozzle head.

5. At least two or more people should hold the heads of water spray guns and spray water on the fire source until the fire is extinguished.

Fire hoses are hoses used to transport high-pressure water or fire-retardant liquids such as foam. Traditional fire hoses are lined with rubber and wrapped with a braided linen outer surface. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or a nozzle to increase the liquid spray pressure.

Fire hoses are divided into two categories: lined fire hoses and leaking fire hoses. Lined fire hoses include rubber fire hoses, TPU fire hoses, polyester glue-filled hoses, and hemp plastic-coated hoses. According to the working pressure, it is divided into four categories: 0.8MPa, 1.0MPa, 1.3MPa and 1.6MPa. According to the diameter, it is divided into four categories: 50, 65, 80 or 75, 90 mm. According to the weaving method, it is divided into two categories: plain weave water belt and twill water belt. The length of each water belt is generally 20 meters. 

The fire jet spray nozzle is the main equipment used by firefighters when extinguishing fires. It can convert the high-pressure water flow in the hose into a high-speed jet of the water gun.

It is used to direct water flow from a fire hose. It is typically attached to the end of a hose and is designed to divide the water flow into multiple directions, allowing firefighters to extinguish a fire from various angles.

Branch pipes come in different sizes and shapes, depending on their intended use and the volume of water flow required. They are made of durable materials that can withstand high pressure and extreme temperatures, ensuring that they perform effectively during emergency situations.

Fire hose reel and assembly used in the hydrant system includes angle hose valve, hose reel, reel nozzle, and kinds couplings and adaptors. They are matched with each other and play an important role in the field of fire protection.
