🖊 شیر گلوب برای تنظیم فشار جریان در یک خط لوله استفاده می شود؛ وقتی شیر در خلاف جهت عقربه‌های ساعت چرخانده شود، بخار و سوپاپ در جهت بالا در طول خط جریان سیال حرکت می کنند و شیر باز شده و جریان سیال را از طریق دریچه عبور می‌کند.
📌 این نوع شیرها برای کنترل و تنظیم جریان سیال کاربرد دارند، الگوی جریان سیال در شیر گلوب دچار تغییر جهت می‌شود و در نتیجه مقاومت بیشتری در برابر جریان ایجاد می شود و باعث افزایش افت فشار می‌شود.
🔰در انتخاب شیرهای گلوب باید به نکات زیر توجه شود:
🔸محدودیت سایز (۱ اینچ تا ۲۴ اینچ) 🔸محدودیت ظرفیت در مقایسه با Ball Valve و Butterfly 🔸قیمت بالا 🔸در سایزهای بالا، محدودیت در کلاس نشتی (leakage class)

"We're seeing really dramatic moves, and it's all really tied to Ukraine right now, and in a secondary way, in terms of interest rates," Octavio Marenzi, CEO of Opimas, told Yahoo Finance Live on Thursday. "This war in Ukraine is going to give the Fed the ammunition, the cover that it needs, to not raise interest rates too quickly. And I think Jay Powell is a very tepid sort of inflation fighter and he's not going to do as much as he needs to do to get that under control. And this seems like an excuse to kick the can further down the road still and not do too much too soon." At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows.
