Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a split type sprinkler nozzle. Background Art

[0002] Fire sprinkler heads are used to discharge water at the end of the fire electrical sprinkler system. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. There are drooping sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads and split sprinkler heads, among which the split sprinkler heads separate the thermal sensitive element from the water outlet to avoid mutual interference.

[0003] At present, the existing split sprinkler nozzles lack a protective structure, are often damaged or even unusable due to collisions during transportation, and are not sufficiently wear-resistant, which reduces their service life. Therefore, we propose a split sprinkler nozzle. Utility Model Content
