description	The utility model discloses a grinding machine for the portable check valve, belonging to a special-purpose tool which is used to grind the valve seating sealing face of the check valve and the sealing face of the valve flap. In the utility model, an inner cavity is arranged in the lower clutch, the upper part of the clutch is provided with a limiting opening, and the position of the aligning seat ball face approaching to a transmission rod is provided with a limitator. When the limitator is butted to the limiting opening, the complete appliance can be raised from the valve body. Contrary, the aligning ball face of the transmission rod is butted to the base plane of the inner cavity of the lower clutch. The structure of the utility model is compact and reasonable, and therefore, the utility model is especially suitable for the grinding machine manufacturing various minitype check valves with high, middle or low voltage. The grinding head and the sand paper can be replaced at any time, the grinding efficiency is improved more than five times than the manual grinding, and the power head is added to form a power grinding machine.
