What is the function of the heat collecting plate?

Improve the reaction sensitivity of the nozzle.

The heat collecting plate, also called the heat collecting hood, is used to collect heat at the nozzle. The main purpose of setting the heat collecting cover is to improve the reaction sensitivity of the nozzle and respond to the nozzle action in advance. In order to facilitate heat collection, the periphery of the heat collection baffle is required to be bent downward, and the height of the bent edge should be flush with the splash plate of the nozzle.

The standard clause "Heat-collecting water baffle" stipulates that the sprinkler in the shelf is located below the closed layered partition that can block smoke, and it is required to install a heat-collecting water baffle that can block smoke, collect heat and block water above the sprinkler.
