The opening and closing part of the Globe Valve is a plug-shaped valve disc, the sealing surface is flat or sea-cone, and the valve disc moves linearly along the centerline of the valve seat. The movement form of the valve stem also has a lifting and rotating rod type, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Thus, this type of cut-off valve is veritably suitable for cutting or regulating, and throttling. Because the opening or ending stroke of the stopcock stem of this type of stopcock is fairly short, and it has a veritably dependable cut-off function, and because the change of the stopcock seat opening is commensurable to the stroke of the stopcock slice, its veritably suitable for inflow adaptation. Next, let's take a look at the conservation of Globe Valve.
