◎ Application scenarios: Liquefied natural gas (LNG) process systems, used for flow regulation and control of system pressure; chemical process
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
The slow-closing check valve opens and closes the valve disc automatically due to the flow of the medium, and is a type of automatic valve used to prevent the backflow of the medium. It is mainly used to prevent backflow of the medium, prevent the reverse rotation of pumps and drive electric motors, and release the medium in containers. The check valve can also be used in pipelines that supply supplementary pressure to auxiliary systems where the pressure may rise above the system pressure.
