Prohibit 1 Hydraulic test shall be carried out under Negative temperature during winter construction. Consequence: Due to the rapid freezing inside the pipe during the hydraulic test, the pipe freezes out. Measures: Try to conduct a water pressure test before winter construction, and after the test, blow the water clean, especially the water inside the valve must be removed completely, otherwise t...

Ball valve structure There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flo...

Compared with other types of valves, pneumatic ball valves have advantages such as angular stroke output torque, fast opening speed, stability and reliability, and wide application： 1. The thrust bearing reduces the Friction torque of the valve stem, which can make the valve stem run smoothly and flexibly for a long time. 2. Anti static function: There is a spring installed between the ball, valve...
