The utility model provides a mechanical linkage three-way
ball valve, which relates to the technical field of ball valves, and comprises a three-way
ball valve body, a pipeline is inserted on the
peripheral side of a group of three-way
ball valve bodies, the group of three-way ball valve bodies are connected through the pipeline, a
valve seat is arranged at the top of the three-way ball valve bodies, a control box is arranged at the top of the
valve seat, and the control box is connected with the three-way ball valve body. A linkage control
assembly is arranged in the control box, a
rotating disc is arranged at the top of the control box, the control
assembly comprises a set of rotating shafts installed at the bottom of the control box, a rotating rod is arranged between the rotating shafts, and one end of each rotating shaft penetrates through the
valve seat and extends into the three-way valve ball valve body. The other end of the rotating shaft is sleeved with a first gear through a bearing seat, a set of grooves are formed in the side walls of the two sides of the control box, and T-shaped movable blocks are arranged in the set of grooves. The three-way ball valve solves the problems that when two sets of existing three-way ball valves work and the
water flow direction needs to be switched at the same time, synchronization of operation cannot be guaranteed, and efficiency is low.
