Problems solved by technology

[0002] At present, the stage interval control between each pulse of the multi-pulse gas generator is mostly realized by the control valve, and the opening and closing of the valve needs to be controlled by the hydraulic control system. Stability, high production cost, high multi-pulse gas generating device is not required for control accuracy, the use of control valve is undoubtedly a great waste of resources

Embodiment 1

[0022] A plug-type interlayer disclosed in this embodiment for a multi-pulse gas generator includes: a mounting sleeve 1 , a connecting screw 2 , a plug 3 , and a gasket 4 .

[0023] The plug 3 is shaped like a trapezoidal cylinder in cross section, the first half of which is a cylinder, and the second half of which is a cone.

[0024] The outer surface of the installation sleeve 1 is a cylinder, the first half of the inner surface is cylindrical, and the second half is conical, which matches the shape of the plug 3 . Threaded holes are formed on the side of the mounting sleeve 1 with a larger inner hole diameter, and the threaded holes are distributed symmetrically in the circumferential direction. The outer surface of the mounting sleeve 1 is threaded.

[0025] Connection relationship: the plug 3 is placed in the installation sleeve 1; the gasket 4 is placed on the plug 3 and the installation sleeve 1; the connecting screw 2 is fixed and installed in the threaded hole of th...

Abstract

The invention discloses a plugging-type interlayer for a multi-pulse fuel gas generation device, relates to a plugging-type interlayer, and belongs to the field of fuel gas generators. The plugging-type interlayer comprises an installation sleeve, a connection screw, a plug and a gasket. The plug is arranged inside the installation sleeve. The gasket is placed on the plug and the installation sleeve. The connection screw is fixedly installed inside a threaded hole of the installation sleeve through the gasket, so that the effect of fixing the gasket and the plug is achieved. The invention further discloses a using method of the plugging-type interlayer for the multi-pulse fuel gas generation device. According to the plugging-type interlayer, external threads are tapped on the outer surface of the installation sleeve, machining and installation are convenient, the replaceability is high, the plugging-type interlayer can be designed into different types according to different application occasions, meanwhile, axial one-way limiting of the structure of the plug is sufficiently utilized, it is ensured that the pulses in the multi-pulse fuel gas generation device can normally and independently work, the structure is simple and reliable, and the cost is low.

Description

technical field [0001] The invention relates to a plugging interlayer, in particular to a plugging interlayer used for a multi-pulse gas generator, and belongs to the field of gas generators. Background technique [0002] At present, the stage interval control between each pulse of the multi-pulse gas generator is mostly realized by the control valve, and the opening and closing of the valve needs to be controlled by the hydraulic control system. Stability, high production cost, and a multi-pulse gas generating device that does not require high control accuracy, the use of control valves is undoubtedly a great waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plugging interlayer for a multi-pulse gas generating device, which fully and skillfully utilizes the structural characteristics of the plugging itself to ensure that each pulse is independent of each other when the multi-pulse gas generat...
