Ball valve with square bore and quarter turn component

摘要

The invention relates to a turned regulating ball valve, which comprises a ball valve body, a ball and a stem mechanically fixed with the ball, the ball can be rotated by 90 degrees in the ball valve body using the stem as an axis, a first side and a second side of the ball valve body are respectively provided with an inlet seat and an outlet seat, the ball valve body and the inlet seat are provided with an inlet fluid passage, the ball valve body and the outlet seat are provided with an outlet fluid passage, the ball is placed between the inlet seat and the outlet seat, a first part of the ball, which is close to the inlet seat, is provided with a control assembly, and a second side of the ball, which is close to the outlet seat, is provided with a plurality of hole fluid channels which communicate with the control assembly. The turned regulating ball valve has the advantages that are: enlarging a fluid flow area at an entrance of the ball; enabling accurate regulations; allowing regulations under a high pressure differential.
