Multifunctional intelligent nozzle structure

Abstract

The invention discloses a multifunctional intelligent nozzle structure used by a dry powder extinguisher. The multifunctional intelligent nozzle structure comprises a valve body, an inflation pressing valve, a pressure meter connecting head and a thermosensitive valve; a powder spraying pipe is arranged at the upper end of the valve body, and a connecting port is formed in the lower end of the valve body; a pressure meter joint is formed in one side of the valve body and an inflation pressing port is formed in the other side of the valve body; the pressure meter joint of the valve body is connected with a pressure meter through the pressure meter connecting head; the inflation pressing port of the valve body is connected with the inflation pressing valve; and the valve body is connected with an outlet of the dry powder extinguisher through a connecting port. The thermosensitive valve coats the powder spraying pipe, and is welded with the powder spraying pipe through tin soldering; and when the temperature of the thermosensitive valve reaches the melting temperature of tin soldering, the thermosensitive valve is deviated from the powder spraying pipe under the effect of pressure, and dry powder is sprayed out from the dry powder extinguisher for automatic fire extinguishing. The multifunctional intelligent nozzle structure is high in reliability without generating wrong control and control failure, prevents fire, can timely extinguish the fire, and prevents and reduces the fire loss.

Description

technical field [0001] The invention relates to a multifunctional intelligent nozzle structure used in a dry powder fire extinguisher. Background technique [0002] The structure of the control valve of the existing automatic control dry powder fire extinguisher is: a plug is plugged at the powder injection port, a glass bottle is set between the plug and the beam, the glass is filled with liquid, the glass bottle is adjusted against the plug, and the liquid in the glass bottle is heated. After expansion, when the liquid expands to a certain volume, the glass bottle breaks, and the glass bottle breaks away from the stopper. Under the internal pressure of the dry powder fire extinguisher, the stopper comes out from the powder injection port, and the dry powder is sprayed out from the dry powder fire extinguisher to automatically extinguish the fire. Its disadvantages are: the glass bottle is easy to be broken automatically, and the powder is automatically sprayed in the case ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the glass bottle is easy to be broken automatically, and the powder is automatically sprayed in the case of no fire; the tip of the glass bottle is prone to liquid leakage. At this time, the glass bottle will not be broken, and the dry powder fire extinguisher cannot automatically spray powder to extinguish the fire, which will cause great casualties and property losses.
