Nozzle protecting blow-off cap insert

Abstract

Assembly and apparatus related to a fire suppression system are described herein. The nozzle cap and insert assembly includes a discharge nozzle, a cap insert, and a nozzle cap. The discharge nozzle includes an aperture on an elongated body such as a cylinder. The cap insert includes a plate and, in some implementations, a sidewall and a perforation. The nozzle cap incudes a cavity with a depth equal to a thickness of the plate of the cap insert and a length of the discharge nozzle. The diameter of the cap insert is structured to substantially or completely cover the top of the discharge nozzle and the thickness of the plate is structured to fit inside the cavity of the nozzle cap. The cap insert is made of a heat-resistive rigid material, similar or the same as the metal of the discharge nozzle.
