Rõhuklapid

Rõhuklapid, also known as pressure relief valves or safety valves, are mechanical devices designed to control or limit pressure in a system. They are critical safety components used in a wide variety of industrial and domestic applications to prevent over-pressurization, which could lead to equipment damage or hazardous situations. The fundamental principle of a rõhuklapp is that it opens automatically when the system pressure exceeds a predetermined set point.

When the pressure inside a vessel or pipe reaches the set pressure, the force exerted on the valve disc overcomes the force of a spring or other counteracting mechanism. This allows the valve to open, releasing fluid or gas from the system. The released fluid or gas reduces the pressure. Once the pressure drops below the set point, the spring force reasserts itself, closing the valve and restoring normal operation.

Rõhuklapid are essential for protecting equipment like boilers, pressure vessels, pipelines, and hydraulic systems. They come in various designs, including spring-loaded, pilot-operated, and rupture disc types, each suited for different pressure ranges and applications. Regular testing and maintenance of rõhuklapid are crucial to ensure their reliable operation and the safety of the system they protect. Their presence is often mandated by safety regulations in many industries.
