Surveühendus

Surveühendus, often translated as "pressure connection" or "pressure coupling," refers to a component or system designed to create and maintain a sealed connection for conveying pressurized fluids or gases. These connections are critical in a wide range of applications, from industrial machinery and automotive systems to plumbing and medical equipment. The primary function of a surveühendus is to prevent leaks, ensure the integrity of the system under pressure, and allow for reliable transfer of the medium.

The design of a surveühendus can vary significantly depending on the specific requirements of the application. Common types include threaded fittings, compression fittings, flare fittings, and quick-connect couplings. Threaded fittings rely on the interlocking of helical threads to create a seal, often augmented by sealing materials like PTFE tape or thread sealant. Compression fittings use a nut and ferrule to compress onto a tube, creating a mechanical seal. Flare fittings involve deforming the end of a tube into a conical shape that mates with a corresponding fitting. Quick-connect couplings offer rapid assembly and disassembly without the need for tools, utilizing O-rings or other sealing mechanisms for a secure connection.

The materials used in surveühendused are chosen based on factors such as the pressure, temperature, and chemical compatibility of the fluid or gas being handled. Common materials include various metals like brass, stainless steel, and aluminum, as well as polymers and specialized elastomers for seals. Proper installation and maintenance are crucial for ensuring the long-term effectiveness and safety of any surveühendus.
