The core of a cast steel ball valve is like a metal ball with a hole, which controls the flow of liquid\/gas by rotating it 90 degrees. This type of valve is very suitable for high pressure and high temperature resistance.
\nThe key components are the steel ball and the valve stem. The steel ball, which is a solid metal ball, has a hole dug in the middle. The hole is aligned with the pipeline for flow, and when it is turned horizontally, it is cut off; The valve stem connects the handle and the ball, and turning the handle drives the ball to rotate. In addition, there is a soft seal that acts to prevent leakage.
\nThis type of cast steel ball valve is mainly used in the following tough character scenarios:
\n1. Oilfield oil pipeline: carrying crude oil under high pressure and hydrogen sulfide corrosion (preventing leakage and ensuring safety).
\n2. Power plant steam pipe: easy to handle 425 \u2103 high-temperature steam (ordinary valves have already become soft).
\n3. Chemical plant reaction tank: switch corrosive liquid (chromium steel alloy protective body).
\n4. Slag conveying pipe: The sphere is coated with hard chromium, and the particles and impurities cannot be scraped off.
\nLow pressure scenarios like water plants do not require cast steel ball valves, there is no need.<\/p>\n
