求翻译：该装置由气缸、电磁换向阀及信号控测元件等组成，主要作用是打开操纵阀杆，使充气阀和灌装阀在逆压的状态下打开对容器进行充气灌装。是什么意思？

The device consists of a cylinder, solenoid valve and signal control and testing components such as the composition of the main role is open to manipulation of the valve stem, pneumatic valves and filling valves to inflatable filling state of inverse pressure to open the container.

The installation comprises cylinder, solenoid valve, and signal detection control devices, and other major role, composition is open to manipulation, filling valves and valve stem filling valve in reverse pressure under the condition of container open filling bottling.

This equipment by the air cylinder, the electromagnetism cross valve and the signal controls measured the part and so on composes, the main function is opens operates the valve lever, causes the charge valve and fills installs the valve to open in under the counter pressure condition to the vessel c

By air cylinder, solenoid valve in the unit and signal controlled logging components, and other components, main role is to open the control valve, pneumatic valves and filling valves are opened for adverse pressure on gas filling the container.
