Abstract This paper investigates the sealing performance of high-pressure, high-flow ball valves. Traditional sealing design methods often prove inadequate for...
Abstract When designing ball valves—especially trunnion-mounted ball valves—disc springs play a critical role in determining overall performance. Disc...
This paper presents the detailed structural design of a nuclear-grade bonnetless bellows globe valve. Design verifications—including flow characteristics,...
Abstract: Driven by the “dual carbon” goals, the demand for natural gas and the LNG import market are expanding, making the stable and efficient...
Abstract: Microcracks in the stems of globe valves used in nuclear power plants are often caused by substandard stem materials, improper heat treatment, stress...
Abstract: This study presents the structural optimization of a cryogenic globe valve for liquid helium and liquid hydrogen applications using epoxy fiberglass...
Abstract: With the rapid development of central heating systems, valves—an essential component—are receiving increasing attention when it comes to selection. This...
Abstract: Wax oil is a gas-phase product generated by the hydrogenation unit. Before entering the cold high-pressure separator, it is injected with a 1:1 mixture...
4.1 Ball Valve The ball valve evolved from the plug valve through design optimization. Its opening and closing components use a spherical sealing structure, allowing...
Abstract: Valves are essential control components widely used across various industrial sectors to accurately regulate fluid flow, pressure, and direction....
