    The foam sprinkler is a foam sprinkler element used in foam spray and closed automatic water spray foam sprinkler system. According to the type of foam liquid used, the foam sprinkler can be selected from suction type nozzle and non-suction type nozzle.

    PT type foam nozzle overview :

    The foam sprinkler is a foam sprinkler element used in foam spray and closed automatic water spray foam sprinkler system. According to the type of foam liquid used, the foam sprinkler can be selected from suction type nozzle and non-suction type nozzle.

    PT type foam nozzle working principle :

    When the foam mixture is transported to the foam nozzle by the pipeline, it is centrifugally atomized by the vortex, and then hit by the splash plate, inhaled and passed through multiple foaming nets to form fine air foam, which is scattered downward in the form of an umbrella-shaped bubble cloud, uniform It covers the surface of the burning material to form a continuous foam covering layer, and extinguishes the fire under the functions of blocking, suffocating and cooling.

    PT type foam nozzle features :

    1. It is composed of a body, a vortex, a splash plate, a connecting rod and multiple foaming nets. Material : stainless steel, copper alloy.

    2. It is suitable for aqueous film-forming foam liquid and fluoroprotein foam liquid. It can extinguish Class A solid fire, Class B oil pool fire, and Class B flowing fire ; it can also spray water alone to extinguish fire.

    3. The foam nozzle is an open nozzle, and the installation method is to install it vertically downward.
