Sprinkler

摘要

The sprinkler has a sprinkler head including a nozzle holder (DA) below a cover plate (DP) and demountable nozzle bodies (DK) in the holder. The cover plate is demounted and the nozzle bodies are exchanged by the demounted cover plate. An extension part (HF) is formed on the nozzle bodies and operates the nozzle bodies during insertion and releasing of the nozzle bodies. The holder is designed such that the nozzle bodies are tilted around a tipping axis horizontally running perpendicular to radiation emitting direction by operating the extension part, and moved from the holder.
