A tolózárak a csővezeték-rendszerek alapvető alkotóelemei, used to control the flow of fluid by opening or closing a gate mechanism. Among the various types of gate valves available, the two most common are the OS&Y (Külső csavar és járom) gate valve and the NRS (Non-Rising Stem) tolózár. While both valves serve the same purpose, they differ significantly in their design, Építkezés, and application. In this article, we will explore the differences between OS&Y and NRS gate valves in detail.
Az automatizált termelés végül megszünteti a munkaerőt, mint a szelepeknél, és más termelő iparágak. We will eventually free our hands.
This is actually a good thing in the long run, and there may be worker unemployment in the short term. But in the long run, efficient production capacity will lead to higher social output and building capacity. Thus allowing everyone to be more productive with less work.
Butterfly valve structure is a type of quarter-turn valve that uses a disc-shaped closure element, a pillangókorongot, to control the flow of fluid. The butterfly disc is mounted on a shaft and is positioned in the center of the valve body, which is a round or oval-shaped pipe. The disc rotates around the shaft to regulate the flow of fluid through the valve.
One-way valves also called ellenőrizd a szelepeket or non-return valves. It is a valve where the fluid can only flow along the inlet and the medium at the outlet cannot flow back.
It use in hydraulic systems to prevent the reverse flow of oil, or in pneumatic systems to prevent the reverse flow of compressed air. They play a crucial role in various industries by ensuring the unidirectional flow of substances in pipelines, systems, and equipment, thereby enhancing safety, efficiency, and performance.
According to the global industrial statistics of developed countries, the gross product of valves is the sum of compressors, fans and pumps, accounting for about 5% of the output value of the entire machinery industry. Egy időben, mint … Olvass tovább
