The invention discloses a spherical sealing valve which comprises a lining, a plunger, a spherical valve and a valve seat, wherein the plunger is located in the left side of the lining and slidably connected with the lining, a hemispherical groove is formed in the center of the right end surface of the plunger, a separation layer is arranged in the lining and located on the right side of the plunger, a sliding through hole is formed in the separation layer in an axis direction, the spherical valve is slidably connected into the sliding through hole, the left side end of the spherical valve is matched with the hemispherical groove, the valve seat is connected into the right side of the lining and located on the right side of the separation layer, a concentric groove coaxial with the sliding through hole is formed in the left side end surface of the valve seat, and a concentric hole is formed in the bottom of the concentric groove. For the spherical sealing valve structure designed by the invention, by adopting the spherical valve, the sealing surface is distributed all over the whole spherical cambered surface, even if a partial damage is caused, a good sealing effect can still be achieved, and abnormal sealing is avoided.
