Function:
The outdoor fire hydrant is for the fire brigade to connect the water source from the outside of the building, including the fire pool to supplement the water source for the fire truck. When a fire breaks out indoors, the fire pipe is prone to burst damage due to high temperature and cannot supply water normally, while the outdoor fire hydrant basically does not Affected by objective factors, the indoor fire hydrant cannot be shared with the outdoor fire hydrant. In order to prevent the fire water supply system from being paralyzed due to damage to a certain fire pipe, it is impossible to use the backup water source to extinguish the fire in time.
Maintainance:
1.The ground fire hydrant should be treated with anti-corrosion regularly to ensure the service life. Periodically check the drain operation of the external fire hydrants. On the other hand, the water distribution pipe network should also use fire hydrant drainage to improve and ensure the water quality of the pipe network. In the implementation of the fire hydrant drainage work, it is necessary to ensure the drainage quality and avoid secondary pollution of the pipe network. It is necessary to use hoses to drain water into rainwater wells. Drainage quality is detected by on-site water intake. It mainly measures water quality indicators such as turbidity and residual chlorine. During the measurement, the water pressure and parameters of the pipe network before drainage are also recorded. The use pressure of the pipe network is used as a parameter to facilitate the operation of the pipe network.
2.Fire hydrant shafts are the same as shafts of other facilities, but they cannot be piled up, blocked, buried, or squeezed. In addition to strengthening inspections, publicity and guidance on fire protection regulations must also be done. In particular, it is necessary to closely cooperate with the local fire department, relying on the law enforcement force of the fire department to maintain and manage fire facilities. The fire department implements regional management in fire fighting, and the maintenance and management of fire hydrants in water supply companies should also be organically combined with the regional management of the fire department to form a joint management to achieve twice the result with half the effort. Spray yellow paint on the fire hydrant cover as a warning to facilitate search and maintenance. The fire hydrant cover can be painted with fluorescent and reflective marks to make it easy to find at night.
