Problems solved by technology

There are very few foreign inflatable nozzles that can meet the inflation pressure of the extrusion servo system. Even if there are products that can achieve it, the volume and weight cannot meet the requirements of spaceflight.
[0003] At present, the domestic inflation nozzle has a single function and low inflation pressure, which cannot meet the inflation pressure requirements of the existing extrusion servo system and has low reliability.

Abstract

The invention belongs to an extrusion type servo system and in particular relates to a novel high-pressure air charging nozzle. The invention provides a novel high-pressure air charging nozzle which is specially designed for an extrusion type servo system and has good sealing performance at the reverse blocked state and can ensure that no air leaks at the nozzle after air is charged. The invention adopts the technical scheme that the novel high-pressure air charging nozzle comprises a one-way valve, a spring, a one-way valve core, a shell, a plugging cap, a protective retainer ring, an O-shaped seal ring and a circlip for a hole, wherein the shell is a hollow tubular body; the plugging cap is arranged at the right end of the shell; a one-way valve support, the spring and the one-way valve core are disposed inside the shell; and the one-way valve support is connected with the one-way valve core through the spring.

Description

technical field [0001] The invention relates to an extrusion servo system, in particular to a novel high-pressure inflation nozzle. Background technique [0002] Foreign servo products have proposed a hydraulic servo system that simply relies on high-pressure gas to squeeze hydraulic oil to generate high-pressure oil to provide hydraulic energy for the servo actuator. According to the scheme of the squeeze servo system, the inflation nozzle is a high-pressure gas cylinder Valve to supply high pressure helium. The inflation nozzle is an important component in the extrusion energy. It not only requires that the high-strength gas cylinder can be filled with 60MPa high-pressure gas, but also that the gas must not leak back from the inflation nozzle after inflation, so as to ensure good reverse sealing. There are very few foreign inflatable nozzles that can meet the inflation pressure of the extrusion servo system. Even if there are products that can achieve it, the volume and w...
