Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, and more specifically, particularly relates to a mechanical linkage three-way ball valve. Background Art

[0002] The working principle of the three-way ball valve is to make the valve open or closed by rotating the valve core. The ball valve is light and small in size, can be made into a large diameter, has reliable sealing, simple structure, and is easy to maintain. The sealing surface and the ball surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries.

[0003] Based on the above, the inventors have found the following problems: when two groups of three-way ball valves need to switch the direction of water flow at the same time, the two groups of three-way ball valves are usually rotated separately. This operation method cannot ensure synchronization and has low efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a mechanical linkage three-way ball valve is provided to achieve a more practical purpose. Utility Model Content

[0007] A mechanical linkage three-way ball valve comprises a three-way ball valve body, a group of three-way ball valve bodies are inserted with pipelines on the circumference of the three-way ball valve bodies, and the three-way ball valve bodies are connected by pipelines, a valve seat is provided on the top of the three-way ball valve body, a control box is provided on the top of the valve seat, a linkage control component is provided inside the control box, a turntable is provided on the top of the control box, the control component comprises a group of rotating shafts installed at the bottom of the control box, a rotating rod is provided between the rotating shafts, and one end of the rotating shaft passes through the valve seat and extends to the inside of the three-way valve ball valve body, a gear 1 is provided on the other end of the rotating shaft through a bearing seat, a group of grooves are opened on the side walls of both sides of the control box, a T-shaped movable block is provided in one group of the grooves, a rack is provided on one side of the T-shaped movable block, a ball valve core is provided inside the three-way ball valve body, the top of the ball valve core is connected to the rotating shaft, a gear 2 is provided on the rotating rod through the bearing seat, and the other end of the rotating rod passes through the top of the box and is connected to the turntable.

[0008] Furthermore, the gear 1 is meshed with the rack, and the gear 2 is meshed with the rack.

[0009] Furthermore, the control box is mounted on the top of the valve seat by bolts.

[0010] Furthermore, sealants are provided at the connection between the pipeline and the three-way ball valve body, and at the connection between the rotating shaft and the valve seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The turntable rotates to control gear 2, which drives the racks on both sides to move, thereby driving gear 1 to rotate, achieving synchronous rotation of the two gears and ensuring synchronous operation.

[0013] 2. The other end of the shaft passes through the valve seat and extends to the inside of the three-way ball valve body, and is connected to the ball valve core. The rotation of the shaft can directly control the rotation of the ball valve core, thereby changing the direction of the water flow path of the three-way ball valve body, which is convenient and quick.
