Fire hydrants for ships CCS fire hydrants

Marine fire hydrant, CCS fire hydrant, all copper fire hydrantUsed to control fire water supply, it is connected to water hoses, water guns, etc. to form an indoor fire extinguishing system. In addition to all the functions of common SN indoor fire hydrants, it also has the functions of freely rotating water outlets and pressure reduction and stabilization. Free rotation brings convenience to installation, and through pressure reduction and stabilization, the pressure after the initial bolt is maintained stable, ensuring safe and reliable use. It can simplify the design and calculation of the fire protection system, simplify the system, and make it an ideal fire extinguishing device in high-rise buildings.

A fire hydrant, officially known as a fire hydrant, is a fixed fire-fighting facility primarily used to control combustibles, isolate combustibles, and eliminate ignition sources. Divided into indoor fire hydrants and outdoor fire hydrants. The fire protection system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some may also have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system, etc. Fire hydrants are mainly used by fire trucks to extract water from municipal water supply networks or outdoor fire water supply networks for fire extinguishing. They can also be directly connected to water hoses or water guns for extinguishing fires. Therefore, indoor and outdoor fire hydrant systems are also one of the important fire-fighting facilities for extinguishing fires.

This series of products complies with the requirements of the "Fire Safety System Rules".
The indoor fire hydrant is an important part of the fire water system. It is installed in the indoor fire box. The general nominal diameter (mm) is DN50 and DN65, the nominal working pressure is 1.6MPa, the strength test pressure is 2.4MPa, and the applicable medium is clean water and foam mixture.
Indoor fire hydrants are fixed fire-fighting facilities for factories, warehouses, high-rise buildings, public buildings, and ships that supply water to the fire scene through indoor pipe networks. They are equipped with valve interfaces and are usually installed in fire hydrant boxes and used in conjunction with fire hoses, water guns, and other equipment.
Placement position:
1. Fire hydrants should be placed in public shared spaces such as corridors or halls, usually within the walls of these spaces. Regardless of the decoration, they must be prominently labeled (indicating 'fire hydrant') and no obstacles should be placed in front of them to avoid affecting the opening of the fire hydrant door.
2. Fire hydrants are isolated in rooms (such as private rooms), which does not comply with fire safety regulations and is not conducive to timely rescue by firefighters.

All interface products nowadays are forged without sand holes or air pockets.
Indoor fire hydrants can usually be divided into ordinary type, pressure reducing and stabilizing type, rotating type, etc. Their fire extinguishing method is to manually connect a water hose to the hydrant mouth for extinguishing the fire. In addition, there is a fire hydrant button inside the hydrant box, which can be pressed to remotely start the fire pump to replenish water to the hydrant.

Installation points:
Fire hydrant: a device connected to the fire water supply system or water supply system, equipped with a switch valve and one or more outlets used to supply water to the fire hose or fire truck. Fire hydrants are divided into indoor fire hydrants and outdoor fire hydrants.
When indoor and outdoor fire hydrants are directly supplied with water from municipal water supply pipes and an independent fire water supply system is used, backflow preventers should be installed at the interface with the municipal water supply network.
The filling time of the dry fire hydrant system should not exceed 3 minutes.
The number of outdoor fire hydrants should be determined based on the comprehensive calculation of the protection radius of the fire hydrant and the fire water consumption of the outdoor fire hydrant. The flow rate of each outdoor fire hydrant should be calculated at 15L/s. Municipal fire hydrants within a distance of 5-40m from the protected object can be included in the number of outdoor fire hydrants.
Outdoor fire hydrants should be evenly arranged around high-rise buildings and should not be concentrated on one side of the building. The number of outdoor fire hydrants on the firefighting surface of high-rise buildings should not be less than 2.
An outdoor fire hydrant should be installed in front of the backflow preventer on the inlet pipe of the municipal water supply network.
The fire water supply network should be divided into several independent sections using valves, and the number of fire hydrants in each section should not exceed 5.
The distance between the outdoor fire hydrant and the fire pump adapter should not be less than 15m or more than 40m.
