Product Description
1. Product descriptionGlobe valve belongs to the forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from below the disc, the resistance to be overcome by the operating force is the friction between the valve rod and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve rod is larger, otherwise the valve rod will be bent. According to the connection mode, it can be divided into three types: flange connection, screw connection and welding connection.

5. Working principle of forged steel globe valve:The opening and closing parts of stop valve (globe valve) are plug-shaped disc, the sealing surface is flat or sea cone, and the disc moves in a straight line along the center line of the valve seat. The movement form of the valve rod (general name: dark rod) and the lifting and rotating rod type 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. Therefore, this type of shut-off valve is very suitable for cut-off or regulation and throttling. Because of the relatively short opening or closing stroke of the valve stem, and the very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for the flow regulation.
