The utility model discloses an advantage and beneficial effect:

1. the utility model provides a split type valve grinder can satisfy the grinding to the lower sealed face of import valve and case respectively through two kinds of equipment modes of grinding pole, grinding stabilizer and grinding head, makes it reach the qualification standard, and it has good result of use to leaking in the restoration valve. The utility model discloses labour saving and time saving proves in the working practice, uses the utility model discloses a split type valve grinder can shorten the restoration grinding time of import valve and be 1-2 hours.

2. The utility model discloses an adopt screw thread turn-buckle swivelling joint between T type grinding rod and the grinding head, have easy and simple to handle, safe and reliable, can greatly improve work efficiency, and when grinding down sealed face clockwise, make it be difficult to drop.

3. The utility model discloses a grinding head concave surface, convex surface all adopt carbide to grind cladding material, have greatly strengthened grinding head hardness, greatly improve the grinding quality.

4. The utility model discloses when using, can receive even grinding for sealed face under guaranteeing, designed and ground the stabilizer, its simple structure can make the grinding head can keep concentric the rotation through the principle of bottle plug, makes the grinding head at valve body internal motion process and speed relatively stable, reaches even grinding.

5. The utility model discloses a grind pole, grind stabilizer and grinding head has adopted split type structure, and pluggable grinds all can be at any time quick assembly disassembly such as stabilizer, improves the convenience of device greatly, convenient to use, carries and keeps.

6. The utility model discloses grinding head up when grinding the case uses inboard grinding coating to grind, and the valve rod can accord with human engineering principle, labour saving and time saving as the atress fulcrum.
