Automatic valve device for extrusion discharging at bottom of mixing pot

Abstract

The invention belongs to the field of valve devices, and particularly discloses an automatic valve device for extrusion discharging at the bottom of a mixing pot. The automatic valve device comprises a valve element unit and a control locking unit, wherein the valve element unit comprises a pot body connecting shell, a plug, a lower plug shell and a central shaft, the plug and the lower plug shell are installed inside the pot body connecting shell, and the lower plug shell is partially nested in the plug; a sealing cover is arranged on the lower plug shell, so that a cavity is formed in the lower plug shell; one end of the central shaft is installed in the lower plug shell, the other end of the central shaft is fixed on the plug, a piston-shaped protrusion is arranged in the middle section of the central shaft, the piston-shaped protrusion divides the cavity in the lower plug shell into two parts, and the two parts of the cavity communicate with an external air source; and the control locking unit is used for fixing the valve element unit at the bottom of the mixing pot. According to the automatic valve device, automatic control over opening and closing of the plug and free disassembly of a valve element are realized, installation and cleaning are convenient, and automation and integration of the device are realized.

Description

technical field [0001] The invention belongs to the field of valve devices, and more specifically relates to an automatic valve device for extruding and discharging materials at the bottom of a mixing pot. Background technique [0002] At present, in the fields of aerospace, military weapons and other fields, there is a great demand for high-viscosity solid rocket propellants. It is mainly composed of oxidizers, combustion agents and a small amount of additives by chemical or physical methods. It has high viscosity and low fluidity. features. [0003] When preparing high-viscosity materials such as solid rocket propellants through a mixer, discharging from the mixing pot after mixing is a key step. At present, the way of discharging the mixing pot is mainly to turn the mixing pot at a certain angle through the turning device, and pour the material out of the mixing pot with manual assistance. However, the current discharge method is not only time-consuming and laborious, i...
