Abstract
本发明公开了一种微流量高压液化气体的恒压恒流量注入装置,包括气体增压液化部分、气体输出部分、压力流量控制部分与压力流量反馈部分;气体增压液化部分包括气体增压泵;压力流量控制部分由直线往复运动机构、双作用缸以及组成桥路的四个换向电磁阀组成,直线往复运动机构带动双作用缸的活塞杆进行精密直线运动,使双作用缸与四个电磁阀、四个单向阀往复切换配合,进行气体连续输出控制;压力流量反馈部分由三个压力传感器组成,用于实现压力流量的五级反馈。本发明的气体注入装置能够将高压微流量气体方便、恒压恒流量地注入到待注容器或设备中,可广泛应用于如聚合物CO2超临界发泡、高压CO2萃取等对气体注入有严格要求的系统中
