Embodiment Construction

[0019] This embodiment is a multi-shot material distribution device for tactical engine charging, including a material distribution nozzle 1, a pressing plate 4, a material distribution cone 5, a material distribution pipe 7 and 6 feeding pipes 9. Such as figure 1 shown. in:

[0020] The edge of the material distribution nozzle 1 is fixed on the upper surface of the pressing plate 4 by bolts, and a large gasket 3 is arranged between the material distribution nozzle and the pressing plate. The lower end of the distribution cone 5 is placed in the distribution nozzle and corresponds to the central hole of the pressing plate. A small sealing gasket 6 is placed between the material distribution cone and the pressing plate. There are 6 distributing pipes 7 evenly distributed on the lower surface of the pressing plate 4 . The upper end of each feeding pipe 9 is fixedly connected with the distribution pipe 7 respectively, and the lower end of each feeding pipe is respectively con...

Abstract

The invention provides a multi-shot feed divider for charging of a tactic engine. The multi-shot feed divider comprises a feed dividing sprayer, pressing plates, a feed dividing cone, feed dividing pipes and six discharging pipes. The edge of the feed dividing sprayer is fixed to the upper surfaces of the pressing plates. The lower end of the feed dividing cone is put in the feed dividing sprayer and corresponds to center holes of the pressing plates. The six discharging pipes are evenly distributed on the lower surfaces of the pressing plates. The upper ends of the discharging pipes are fixedly connected with the feed dividing pipes, and the lower ends of the discharging pipes are fixedly connected with all single-shot pouring sprayers. When an engine combustion chamber is poured, propellant medicine slurry enters all the feed dividing pipes through the feed dividing sprayer via discharging sleeves and then enters an engine shell, and it is achieved that the propellant medicine slurry can be divided into charging processes of multi-shot engines at a time. Pouring efficiency is improved by six times. The problems that during single-shot multi-pouring operation, the pouring total time is long, and the leveling property of the medicine slurry becomes poorer are avoided, multiple times of cleaning are reduced, and the production efficiency of the combustion chamber is improved.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motor charging, and relates to a multi-shot material distributing device in the solid rocket motor charging pouring process. Background technique [0002] Most solid rocket motor combustion chambers use single-shot vacuum intubation pouring molding technology, which consists of a primary hopper, a secondary hopper, a rubber hose valve, a blanking sleeve, a blanking nozzle and a vacuum pouring cylinder. Place the assembled solid rocket motor in the center of the vacuum pouring cylinder, and connect the feeding nozzle, pouring cylinder pressure retaining cover, blanking sleeve, secondary rubber hose valve and secondary hopper, secondary hopper pressure retaining cover and primary Hose valve and primary hopper, after the vacuum degree and water temperature of the secondary hopper and pouring cylinder meet the requirements, the slurry flows from the primary hopper through the hose valve and the d...
