Main features: The sealing surface of the general type plug valve is connected to the plug using a guide rail structure. During the process of valve opening, first lift the plug to a certain height through the transmission mechanism. The two sliders gradually approach the center of the valve as the plug is lifted, detach from the sealing surface, and form a certain gap. Then, continue to rotate the plug and slider together to the open position through the transmission mechanism. Mainly used in the metering system, calibration system, multi branch mixed transportation system, tank root partition, storage and transportation of aviation fuel, airport refueling hydrants, frequent operation of feeding and unloading systems in civil aviation airport oil depots and port finished oil depots.
