Abstract

The invention discloses an indoor fully automatic retractable fire extinguishing nozzle, which comprises a fire extinguishing nozzle slidably installed on the top of a wall. A water pressure chamber and a thermal induction chamber are provided inside the fire extinguishing nozzle. Water pipe, the lower end of the fire-fighting water pipe extends into the hydraulic chamber and is sleeved with a sealing slide plug, and the inner wall of the lower port of the fire-fighting water pipe is equipped with a limit ring. In the present invention, the pressure of the thermal expansion fluid in the thermal induction cavity and the water pressure in the fire-fighting water pipe form a pressure difference through the condensation, pressure-reduction, evaporation, and pressurization of the thermal-expansion liquid. The pressure difference realizes the opening and closing of the fire-fighting water pipe by the rubber ball through the linkage rod and the piston, and realizes automatic fire extinguishing , Automatic recovery function, saving water resources and can be reused.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to an indoor fully automatic retractable fire extinguishing nozzle. Background technique [0002] When buildings are constructed and used, they need to pass qualified fire inspections. The most common automatic fire extinguishing method for building fire protection is the fire extinguishing nozzle on the top of the wall. [0003] Existing fire extinguishing nozzles are broken by thermal induction expansion to open the fire-fighting water pipe, so that the water in the fire-fighting water pipe can be sprayed to extinguish the fire, but it cannot be restored after being broken. Water resources are consumed and cannot be reused. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the prior art that the water cannot be cut off directly after being broken, water resources are wasted and cannot be reused, and an indoor fully automatic retra...
