The utility model discloses a check valve with an anti-misoperation limiting structure, which comprises a valve body, a valve core is arranged in the valve body, an end cover is fixedly connected to the outer wall of the top of the valve body, a valve rod is rotatably connected to the inner ring of the end cover, a connecting rod is movably sleeved on the outer ring of the valve rod, a rotating handle is fixed at the upper end part of the connecting rod, and the valve core is fixedly connected with the valve rod. The device further comprises a synchronizing mechanism. And the outer ring of the connecting rod is fixedly sleeved with a disc, and the lower end of the disc is fixedly connected with a limiting rod. By loosening the rotating handle, the self-bearing force of the rotating handle and the connecting rod is reduced, so that the magnetic block II in the connecting rod and the magnetic block I at the top of the valve rod attract each other, the limiting rod is ensured to be clamped in the limiting clampi
