Abstract

The invention discloses an indoor full-automatic telescopic fire extinguishing nozzle. The fire extinguishing nozzle comprises a fire extinguishing nozzle body slidably mounted at the top of a wall. Awater pressure cavity and a thermal induction cavity are formed in the fire extinguishing nozzle body, a fire hose is slidably inserted in the upper end of the fire extinguishing nozzle body, the lower end of the fire hose extends into the water pressure cavity and is sleeved with a sealing sliding plug, and a limiting ring is mounted on the inner wall of a lower end opening of the fire hose. Thepressure difference is formed between the thermal expansion liquid pressure in the thermal induction cavity and the water pressure in the fire hose through the condensation, depressurization, evaporation and pressurization effects of thermal expansion liquid, a rubber ball can be removed from or seal the fire hose through a linkage rod and a piston based on the pressure difference, the functionsof automatic fire extinguishing and automatic recovery are achieved, water resources are saved, and repeated use is achieved.

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...
