Description

Technical Field

[0001] The utility model belongs to the technical field of ship valves, and particularly relates to a grinding device for ship valves. Background Art

[0002] Valves are essential control elements for fluid control in ship piping systems. For fluid control systems, valves play an important role in opening and closing the flow of media and controlling the flow, pressure and flow direction of the fluid.

[0003] After a valve has been used for a long time, its sealing surface is susceptible to water corrosion, causing the sealing surface to become uneven. The sealing surface is no longer flat, and the flatness of the valve sealing surface is damaged, which affects the subsequent use of the valve, for example, the valve may leak.

[0004] For the above problem, if the sealing surface of the valve is not seriously corroded, it can be repaired by grinding so that the flatness of the sealing surface meets the use requirements. If the sealing surface of the valve is seriously corroded, it is necessary to replace it with a new valve. After the new valve is replaced, it needs to be inlaid with a copper ring and then ground flat when used.

[0005] At present, at ship production sites, various types of ship valves that have been corroded by water are manually ground flat. The operator holds the valve and inserts different grinding heads into the sealing surface inside the valve according to requirements, and then manually rotates the grinding head to grind it flat. Although this method is simple to operate, it is labor-intensive and has low work efficiency. Utility Model Content
