Description

Water spray head for fire control

Technical Field

The utility model belongs to the technical field of fire-fighting equipment, and particularly relates to a sprinkler head for fire protection.

Background

The water system fire extinguishing has the advantages of high efficiency and environmental protection, and plays an important role in fire control. One of the key parts in the water-based fire extinguishing system is a spray head, the water-based spray head can be divided into three types of spray heads, namely a water spray head, a water mist spray head and a fine water mist spray head according to the particle size of water drops, and the average particle size and the flow of water mist generated by the three types of spray heads are gradually decreased. In general, the sprinkler head and the water mist head have strong penetrating capability and are more effective for solid fires and fire with larger fire and long-distance spraying; the water mist spray head and the water mist spray head have small droplet diameter and are effective for liquid fire and fire or when the combustion objects are required to be protected. Because of the complexity of fire, the sprinkler head, the water mist head and the water mist head are generally required to be switched in the same fire. The existing sprinkler head needs to be replaced by manpower, the working efficiency is low, the sprinkler head is replaced temporarily, and the fire disaster is not easy to extinguish in time. In addition, the existing spray heads are generally only single spray heads, the protection radius is smaller, the fire extinguishing efficiency is lower, and the spray heads cannot be used in occasions with higher fireproof requirements.
