Abstract

The invention relates to a diaphragm assembly. The diaphragm assembly comprises a rupture diaphragm, a gasket and a grate. The outer diameter of the gasket is smaller than that of the grate. The gasket is designed with a blind hole. The rupture diaphragm is designed with a protrusion block. When the diaphragm assembly is assembled, the protrusion block on the rupture diaphragm is embedded into the blind hole of the gasket, and one side provided with a nick, of the rupture diaphragm is fitted to the grate. When the diaphragm assembly is mounted, the grate is connected to a flange on the upstream side of the air flow. The diaphragm assembly is made of a pure copper diaphragm and accordingly has good compatibility with high-temperature and high-speed oxygen. The fail-proof design is used for ensuring that the rupture diaphragm is not mounted reversely when the diaphragm assembly is assembled and the diaphragm assembly is not reversely mounted in a pipe.

Description

[0001] technical field [0002] The invention relates to a diaphragm assembly, in particular to a diaphragm assembly used for self-generated pressurization of a liquid oxygen storage tank of a launch vehicle. [0003] Background technique [0004] The diaphragm assembly is an important stand-alone unit used in the pressurized delivery system of the launch vehicle. Its function is to separate the liquid oxygen storage tank from the pressurization system by means of the diaphragm assembly before the engine starts. The disc ruptures, pressurizing the tank. [0005] In the known diaphragm assembly used in the existing pressurized conveying system, the material of the ruptured diaphragm in the diaphragm assembly is pure aluminum plate, and there are hidden dangers of sparks and deflagration in the pure aluminum diaphragm under high temperature and high speed oxygen scour. [0006] In the diaphragm assembly, the side of the grille and gasket in contact with the ruptured diaph...
