Abstract

A six-way switching ball valve belongs to the switching valve, which solves the problem that the inlet and outlet of the existing six-way switching valve are all arranged on the same side, resulting in limited application occasions. The present invention consists of an upper three-way ball valve, a lower three-way ball valve and a drive conversion mechanism. The structure and components of the upper three-way ball valve and the lower three-way ball valve are exactly the same. Rotary shaft, thrust ring, flange gland, rotating block, steel wire retaining ring; the drive conversion mechanism includes handle, bevel gear, gearbox, input shaft, ball bearing, upper output shaft, lower output shaft, drive conversion The upper and lower output shafts of the mechanism are matched and connected with the rotating shafts of the upper and lower three-way ball valves respectively. The invention has the advantages of simple structure, small switching torque, different side arrangement of the inlet and outlet, and solves the problem of limited application occasions of the arrangement of the same side of the inlet and outlet. Strong performance, making the on-site pipeline layout more flexible.

Description

technical field

[0001] The invention belongs to switching valves, in particular to a six-way switching ball valve, the inlet and outlet of which are arranged on different sides. Background technique

[0002] As an important fluid pipeline reversing equipment, the six-way switching ball valve is widely used in petrochemical, metallurgical and other industries, while the switching device of the existing six-way switching ball valve is set on the top, the top drive shaft is connected to the upper ball, and the intermediate shaft Realize the connection of the upper and lower spheres to ensure the synchronous movement of the upper and lower spheres. The inlet and outlet are set on the same side, and a certain torque is applied to the drive shaft. The drive shaft drives the upper sphere to rotate, and then transmits the torque to the lower sphere through the intermediate shaft; This structure determines that the upper and lower spheres will rotate clockwise or counterclockwise at ...
