China Safety Valves Lapping Machine, Find details about China Safety Valve, Valve from Safety Valves Lapping Machine
| Advantages: This kind of lapping machine adoptes the combined dynamic grinding methods of dynamic grinding for | ||||||||
| valve seat, of multi direction & multi track grinding for valve clack. Equipped with hard alloy grinding plate with large | ||||||||
| diameter, grinding quality guaranteed. Easy to operate and large scope application; Efficient and reducing labor | ||||||||
| strength of workers, grinding effect guaranteed. |
| Principle of Operation and Design Features: | ||||||||
| 1. Enjoy the advantages of good grinding effect by pure manual grinding and of time-saving & labor-saving by mechanical | ||||||||
| grinding. | ||||||||
| 2. Featured with threefold grinding trajectory, thus sealing surfaces of the safety valves can get multi-faceted, efficient and comprehensive | ||||||||
| repair. Equipped with large diameter hard alloy grinding plate with φ450mm, thus can grind a variety of valve clacks with different | ||||||||
| specifications. | ||||||||
| 3. Introduction to threefold grinding trajectory: | ||||||||
| (1) Outer-ring grinding plate enjoys counterclockwise rotation; | ||||||||
| (2) Central-ring enjoys clockwise elliptical rotation through eccentric wheel linkage. | ||||||||
| (3) The impact rod bring along the porous plate rotates counterclockwise in the outer ring. |
| Technical Parameters: | ||||||||
| 1. Test scope of DN: | DN32~150mm; | |||||||
| 2. Drive: | AC 220V; | |||||||
| 3. Structure: | Valve seat & valve clack, the double location rotational structure. | |||||||
| 4. The imported components can adjust the frequency control. | ||||||||
| Accessories: | ||||||||
| Hard alloy grinding head: | Nine grades of grinding heads with DN 20, 25, 32, 40, 50, 65, 80, 100, 150mm; | |||||||
| Cast-iron grinding plate : | One piece, used for coarse grinding badly worn valve clacks with φ300mm by hand; | |||||||
| Hard alloy Grinding plate: | One piece, used for precision grinding valve spool with φ300mm; | |||||||
| Grinding paste: | Each 2 boxes for Coarse Grinding, Medium Grinding, Fine Grinding, Extra-fine Grinding; | |||||||
| Remark: Coarse & medium grinding paste is only used for rough grinding by hand. | ||||||||
