globe type control valve,
cryogenic control valve
The opening and closing part of the angle-type cut-off valve is a plug-shaped valve disc, the sealing surface of which is flat or conical, and the valve disc moves linearly along the center line of the fluid. There are lifting rod types for valve stem movement (the valve rod is raised and
lowered, and the hand wheel does not rise and fall), and there are also lifting and rotating lever types (the hand wheel and the valve stem are
rotated and raised together, and the nut is provided on the valve body). Corrugated globe valve is only suitable for full open and full close, and it is not allowed to adjust and throttle.
The insulation cut-off valve is a compulsory sealed valve, so when the valve is closed, pressure must be applied to the disc to force the sealing
surface to not leak. When the medium enters the valve 6 from below the valve disc, the resistance to be overcome by the operating force is the
frictional force of the valve stem 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. The diameter of the stem must be large, otherwise the failure of the valve top bend will occur. After the self-
sealing valve appeared, the medium flow direction of the shut-off valve changed from above the valve disc into the valve cavity. At this time, under
the action of the medium pressure, the force to close the valve is small, and the force to open the valve is large, and the diameter of the stem can
be corresponding To reduce. At the same time, this type of valve is also tight under the action of the medium. China's valve "Sanhua" has
stipulated that the flow direction of the shut-off valve will be used from top to bottom.
