The utility model is further provided that one end of the threaded rod close to the discharge through hole is provided with a water discharge groove, the side surface of the threaded rod is provided with a water discharge hole communicated with the water discharge groove, and the water discharge hole is positioned in the middle of the threaded rod.

The utility model is further provided that the threaded rod is also sleeved with a sealing gasket, and the sealing gasket abuts against the cover body.

In conclusion, the utility model has the beneficial effects that:

1. the central handle that the spheroid upper and lower place is located same axis can be convenient installs the spheroid with the connection handle, and the reliability of installation is guaranteed in the center that the spheroid can be installed the spheroid to the central handle, and the discharge through-hole that sets up in the central handle can discharge the medium in the spheroid for when the valve body is in the closed condition, there is not the existence of medium in the spheroid, has reduced medium to spheroidal corruption, corrosion, has improved spheroidal life.

2. The sealing cover at the bottom of the central handle can control the discharge of media in the media channel, and the arrangement of the water drainage groove and the water drainage hole on the threaded rod can ensure that the sealing cover is still connected with the central handle while discharging the media, so that the loss of the sealing cover is avoided.

3. The roller of the periphery of the central handle can be mutually abutted with the valve body, so that the rotation of the ball body is more convenient, and meanwhile, the spring is arranged between the sliding block and the inner wall of the annular groove, so that the mutual abutting of the ball and the valve body is ensured, and the reliability in use is improved.
