Compared with other types of valves, the advantages of using ball valves mainly include the following aspects:
Fast opening and closing: The ball valve adopts rotary operation, which can quickly realize the opening and closing action, the time required is short, and the response speed is fast.
Low fluid resistance: The fluid channel of the ball valve is smooth inside, and the resistance to flow when the valve is opened is small, which is conducive to the smooth passage of the fluid.
Good sealing performance: The ball valve adopts a sealing ring made of elastic materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing force increases with the increase of medium pressure. It has a two-way sealing function and is suitable for a variety of corrosive medium environments.
Long service life: Since materials such as polytetrafluoroethylene have good self-lubrication and small friction loss with the ball, the service life of the ball valve is long.
Anti-static function: A spring is set between the ball, the valve stem, and the valve body to guide the static electricity generated during the switching process to ensure the safety of the system.
Fireproof and explosion-proof: The fireproof ball valve adopts a high platform structure, full-diameter or reduced-diameter design, and has an automatic pressure relief function to ensure the safe operation of the valve under high temperature or abnormal pressure conditions.
Applicable scenarios and industry applications of ball valves:
Ball valves are suitable for a variety of industrial fields, including electricity, petroleum, chemical industry, gas, etc. They perform particularly well in environments containing chloride ions and can replace some high-alloy austenitic stainless steel ball valves and corrosion-resistant alloy ball valves. In addition, pneumatic ball valves are often used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.
