The invention relates to the technical field of space application equipment, in particular to a vacuum chamber for an on-orbit standard experiment, which comprises a square vacuum chamber and a circular vacuum chamber, and is characterized in that the circular vacuum chamber comprises an upper chamber, a middle chamber and a lower chamber which are connected in sequence; the middle chamber and the lower chamber are fixed on the mounting bracket; the square vacuum chamber is fixed at the top of the upper chamber; a plurality of valves and a valve body controller are arranged on the outer wall of the middle cavity; an electric connector is arranged on the outer wall of the lower cavity. According to the invention, through the combination of the square vacuum chamber and the circular vacuum chamber, a vacuum environment is provided in an on-orbit standard experiment process, and through various valves and interfaces arranged on the outer wall of the chamber, the functions of standard power supply, gas supply and feed liquid cooling of mechanisms in the chamber are realized. On-track mounting and dismounting are simple, convenient and reliable, and connecting screws cannot be disengaged.

    本申请涉及空间应用设备技术领域,具体而言,涉及一种在轨标准实验用真空腔室,包括方形真空室和圆形真空室,其中:圆形真空室包括依次连接的上腔室、中腔室以及下腔室;中腔室和下腔室固定在安装支架上;方形真空室固定在上腔室的顶部;中腔室的外壁上设置有多种阀门以及阀体控制器;下腔室的外壁上设置有电连接器。本申请通过设置方形真空室和圆形真空室组合设置的形式,实现了在轨标准实验过程中真空环境的提供,通过设置在腔室外壁上的各种阀门和接口,实现了对腔室内机构的标准供电、供气以及供液冷却的功能,在轨安装与拆卸简单方便可靠,连接螺钉不会脱出。
