Rõhuklapp

Rõhuklapp, often translated as pressure relief valve or safety valve, is a type of valve that protects a pressure vessel or system from overpressure. It is designed to open automatically when the pressure inside the vessel or system exceeds a predetermined limit. This release of pressure prevents potential damage to the equipment or a dangerous explosion.

The operation of a rõhuklapp is typically based on a spring-loaded mechanism. Inside the valve, a disc is held against a seat by a spring. When the internal pressure exceeds the force exerted by the spring, it pushes the disc away from the seat, opening a path for the overpressure to escape. Once the pressure drops back to a safe level, the spring forces the disc back into its seat, closing the valve.

Rõhuklappide are crucial safety devices used in a wide variety of applications. They are commonly found in boilers, pipelines, compressed air systems, steam systems, and refrigeration units. The specific design and set pressure of a rõhuklapp are determined by the requirements of the system it is protecting. Regular inspection and maintenance are essential to ensure that these safety devices function correctly when needed. Failure of a rõhuklapp can have severe consequences, highlighting their importance in industrial and domestic safety.
