DEVICE FOR FORCED GAS EXCHANGE IN SEALED CONTAINER Russian patent published in 2012 - IPC F17C13/02 

FIELD: machine building.

SUBSTANCE: device includes control unit formed as per the pre-set algorithm built using logic communication of electric parameters of automated system components, which comprises electric power supply, analogue-to-digital converter of information and power control signals in the form of interface conversion unit, sensors recording the parameters of automated system, switching devices of information and power control signals in the form of interface input-output unit, which are electrically connected to digital electronic computing device and connected to electric drive of adjustable actuating device; actuating device proper and electric drive of adjustable actuating device, and pneumatic line connecting the actuating mechanism to sealed container. As actuating device there used is electric pneumatic valve connected immediately to one of two outlets of sealed container and connected to pneumatic line with additional filter and micro pump at the outlet of pneumatic line, which are interconnected with environment. Oxygen sensor, as well as microprocessor, are installed immediately at the second outlet of sealed container. Oxygen sensor, micro pump, microprocessor and electric pneumatic valve have direct and return electric communications to the control unit via control and power supply chains. The algorithm, as per which the control unit is formed, is built based on logic connection of initial readings and results of current measurements of oxygen concentration from time period during which allowable oxygen consumption will occur in sealed container.

EFFECT: simpler device design and minimisation of dimension and weight characteristics.
