An aviation fire extinguishing component

Abstract

The invention provides an aviation fire extinguishing assembly. The aviation fire extinguishing assembly comprises a valve body and a splash plate. A temperature sensing element is arranged between the splash plate and the valve body. A spray outlet is formed in the bottom of the valve body, and a plug body is arranged at the bottom of the spray outlet. The splash plate comprises an annular seat and an annular plate. A supporting component is inserted in the annular seat. The supporting component comprises a baffle, a column body and a fixing block. The column body is inserted into the annularseat and is in threaded connection with the annular seat. A first slot hole is formed in the top surface of the column body. A second slot hole is formed in the bottom of the first slot hole. An annular supporting seat is arranged in the first slot hole. One end of the temperature sensing element is abutted against the plug body, and the other end of the temperature sensing element is abutted against the supporting seat. An electric heating tube is arranged in the second slot hole. The top of the electric heating tube is abutted against the bottom of the temperature sensing element. The aviation fire extinguishing assembly is novel in structure, convenient to disassemble and assemble and good in sealing performance and facilitates installation or replacement operation of the temperature sensing element; and an automatic and manual double-opening method is adopted, and the success rate of opening fire extinguishing equipment in case of safety accidents is increased without affecting the normal spraying of an extinguishing agent.

Description

technical field [0001] The present invention relates to the field of fire extinguishing components, more specifically, to an aviation fire extinguishing component. Background technique [0002] In the field of large civil aviation aircraft, fire is one of the most dangerous threats to aircraft, no matter whether the aircraft is in flight or on the ground; therefore, fixed fire alarms are usually installed on the power plant and certain parts of the aircraft body. Detectors and fire extinguishing equipment to protect possible "fire areas"; however, most of the nozzles of some fixed-installed fire extinguishing equipment adopt a temperature-sensitive opening method, which will only start when the external temperature reaches the damage temperature of the temperature-sensing element; Or some use a striking opening method, setting a striking structure on the side of the temperature sensing element. When it needs to be activated, just open the striking structure, but this method ...

[0002] In the field of large civil aviation aircraft, fire is one of the most dangerous threats to aircraft, no matter whether the aircraft is in flight or on the ground; therefore, fixed fire alarms are usually installed on the power plant and certain parts of the aircraft body. Detectors and fire extinguishing equipment to protect possible "fire areas"; however, most of the nozzles of some fixed-installed fire extinguishing equipment adopt a temperature-sensitive opening method, which will only start when the external temperature reaches the damage temperature of the temperature-sensing element; Or some use a striking opening method, setting a striking structure on the side of the temperature sensing element. When it needs to be activated, just open the striking structure, but this method will affect the spraying of the fire extinguishing agent to a certain extent. Reduce the coverage area of ​​the fire extinguishing agent; and it is inconvenient to disassemble and assemble the components of the existing valve body, and it is troublesome to install or replace the temperature sensing element
