一种便携式减压充氮设备的设计与应用

Design and Application of Portable Pressure Reducing Nitrogen Filling Equipment

针对充氮设备输入压力小、充气效率低和不便于携带的问题,设计了一种便携式减压充氮设备。通过对内场和外场气源压力范围及发射筒输入口结构的分析,确定了充氮设备的整体设计方案,并对发射筒专用充气接头进行了详细设计。采用三级减压设计,实现了高压降至低压后输出压力和流量的稳定;设计四路输出阀和输出接口,实现了多个产品同时充气的功能;采用便携式机箱设计,方便了充氮设备的搬运。该设备已投入实际生产使用,应用结果表明:该设备结构紧凑、便于携带,实用性强,性能稳定,提高了工作效率。

Aiming at the problems of low input pressure, low inflation efficiency and unportability of nitrogen filling equipment, a portable pressure reducing nitrogen filling equipment was designed. Through the analysis of the pressure range of the inner and outer field air source and the structure of the input port of the launcher, the over all scheme of nitrogen filling equipment is determined, and the special inflatable joint of the launcher is designed in detail. The three-level pressure-relief design is adopted to realize the stability of output pressure and flow after the high pressure drops to the low pressure. The four-way output valve and output interface are designed to realize the function of inflation of multiple products at the same time. Portable case design facilitates the handing of nitrogen-filled equipment. The equipment has been put into practical use, and the application results show that the equipment has compact structure, easy to carry, strong practicability, stable performance and improved work efficiency.
