légzárás

Légzárás is a Hungarian term that translates to "airlock" or "air seal" in English. It refers to a system or mechanism designed to prevent or control the passage of air between two different environments or spaces. The primary function of légzárás is to maintain a pressure differential, separate atmospheres, or prevent the exchange of contaminants.

In various applications, légzárás systems can be found. In industrial settings, they might be used in cleanrooms or hazardous material containment areas to ensure that air from one zone does not mix with the air in another. This is crucial for maintaining the integrity of sensitive processes or protecting workers from harmful substances. Similarly, in some food processing facilities, légzárás can help maintain sterile conditions.

Another common application is in spacecraft and submarines, where légzárás is essential for life support. Airlocks allow astronauts or submariners to transition between the controlled internal atmosphere and the external environment (space vacuum or underwater) without compromising the integrity of the main cabin. These spaces are typically equipped with mechanisms to equalize pressure and safely open and close doors.

The design of a légzárás system can vary greatly depending on its purpose. It might involve simple sealing techniques, such as gaskets and weatherstripping, or more complex pressurized chambers with multiple doors. Regardless of the complexity, the underlying principle is to create a barrier that effectively stops or significantly limits air movement.
