Abstract

The invention belongs to the field of ignition systems of combustion engines, and particularly relates to the design of a telescopic ignition plug. The telescopic ignition plug comprises a plug assembly, a front flange plate, a rear flange plate, an air cylinder, a spring, a limiting washer, a Sterling seal, a sealing ring and a sealing sleeve. By means of the telescopic ignition plug, ignition inthe no-load state of a combustion engine can be realized, pressure can be supplied through a gas pump under high-pressure high-temperature working conditions, and a plug part can extend into a combustion chamber for ignition again. The problem that the plug part is in a high-pressure high-temperature working environment for a long time can be fundamentally solved, so that the reliability of the ignition plug is improved.

Description

technical field [0001] The invention belongs to the field of gas turbine ignition systems, and in particular relates to a retractable ignition nozzle. Background technique [0002] The ignition system product is an important part of the gas turbine, in which the ignition nozzle is used to convert the high-voltage pulse electricity generated by the ignition device into an electric spark to ignite the fuel in the combustion chamber. The ignition nozzle is generally installed on the casing of the combustion chamber, and the front end of the ignition nozzle is in the combustion chamber. Therefore, the ignition nozzle is in a high-temperature and high-pressure working state for a long time, which seriously affects the product performance and life. Block damage, ignition voltage increase and airtight failure, etc. Contents of the invention [0003] In order to meet the characteristic requirements of high energy and long life of the gas turbine ignition system, the present inven...
