Description

Technical Field

[0001] The invention relates to the technical field of valves, and more particularly to a novel pressure-resistant electric stop valve. Background Art

[0002] When the stop valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the friction between 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, so the diameter of the valve stem must be larger, otherwise the valve stem will bend. When the existing traditional stop valve is used in pipelines such as cross-ways, it usually has a single operation and the slurry of the previous liquid will remain at the stop point.
