Dry Fire Sprinkler Head

A dry sprinkler head (referred to as a dry sprinkler head) is composed of a nozzle frame, a splash tray, a thermosensitive element (glass ball), a ball seat, a spray pipe, an inner pipe, a spring, an outer pipe, a bracket, a sealing element, etc; A dry nozzle can also be understood as a sprinkler head with its own short pipe or water distribution branch, which is a dry pipe that does not allow water to enter when in use.
Dry nozzles are suitable for dry systems and pre action systems where there is a risk of freezing or the ambient temperature may exceed 70 ℃, causing water to vaporize and increase pressure in the pipeline; It can also be applied to wet systems. Similar to regular sprinklers, dry sprinklers are used to detect fires and control and extinguish them through automatic spraying.
