Description

Grinding device for polishing is used in stop valve production

Technical Field

Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the sealing surface not to leak. When a medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force between the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur, and the stop valve is one of the most important cutoff valves and plays an important role in the field of aerospace. As an important element of the aerospace equipment, the stop valve realizes the functions of medium conveying, stopping, adjusting and the like, and the sealing performance of the stop valve directly influences the safe and reliable operation of the aerospace equipment.
