Survetõke

Survetõke is an Estonian term that translates to "pressure barrier" or "pressure relief" in English. It refers to a system or component designed to prevent excessive pressure buildup in a confined space or a fluid system. These barriers are crucial for safety and operational integrity in various engineering applications.

In mechanical systems, a survetõke might take the form of a safety valve, rupture disc, or a relief port. A safety valve is designed to open automatically when a predetermined pressure is reached, releasing the excess pressure and then resealing when the pressure drops to a safe level. A rupture disc, on the other hand, is a sacrificial component that bursts at a specific pressure, providing a one-time pressure relief. Relief ports are typically openings that allow pressure to escape, often used in less critical applications.

The principle behind a survetõke is to maintain system pressure within safe operating limits, preventing damage to equipment, leaks, or potentially catastrophic failures. They are commonly found in boilers, pipelines, hydraulic systems, pneumatic systems, and storage tanks. The design and type of survetõke used depend on the specific application, the fluid being managed, the expected pressure range, and the required response time. Regular inspection and maintenance of survetõke components are vital to ensure their reliable operation.
