The opening and closing parts of the stop valve (Globe Valve) are plug-shaped clappers, the sealing surface is flat or conical, and the valve flap moves linearly along the center line of the fluid. Valve stem movement, (common name: dark bar), there are lifting rotary rod, (common name: Ming rod) globe valve is only applicable to fully open and fully closed, does not allow for regulation and throttling. Stainless steel globe valve is a forced sealed valve, so the valve is closed, the pressure must be applied to the valve flap to force the sealing surface does not leak. When the medium from below the valve into the valve, the operating force needed to overcome the resistance is the valve stem and packing friction and the thrust generated by the media pressure, off the valve force than the valve open, so the valve stem The diameter should be larger, otherwise it will happen valve stem bend. In recent years, since the self-sealing valve appears, the cut-off valve of the media flow to change over from the top of the valve into the valve cavity, then under medium pressure, the valve closing force is small, and open the valve force, the valve stem The diameter can be reduced accordingly. China's valve "three to" have provided that the flow of the valve, all from top to bottom. The valve to be installed at the same time, under the media, this form of valve is more stringent. When the stainless steel cut-off valve is opened, the opening height of the valve flap is 25% ~ 30% of the nominal diameter, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full-stop position of the valve, valve stroke should be determined.
