Six-way switching ball valve

Abstract

The invention discloses a six-way switching ball valve, and belongs to switching valves. The ball valve solves the problem that an inlet and an outlet of an existing six-way switching valve are located on the same side, and consequently an application occasion is limited. The six-way switching ball valve is composed of an upper three-way ball valve, a lower three-way ball valve and a driving conversion mechanism; the structure and component parts of the upper three-way ball valve and the structure and component parts of the lower three-way ball valve are completely the same; each of the upper three-way ball valve and the lower three-way ball valve is composed of a valve body, a ball body, a sealing gasket ring, a sealing check ring, a rotating shaft, a thrust ring, a flange gland, a rotating check block and a steel wire check ring; the driving conversion mechanism comprises a handle, a conical gear, a gearbox, an input shaft, a ball bearing, an upper output shaft and a lower output shaft; the upper output shaft and the lower output shaft of the driving conversion mechanism are connected with the rotating shaft of the upper three-way ball valve and the rotating shaft of the lower three-way ball valve respectively in a matched mode. The six-way switching ball valve is simple in structure and small in switching torque; an inlet and an outlet of the six-way switching ball valve are arranged on the different sides; the problem that the inlet and the outlet are arranged on the same side, and the application occasion is limited is solved; and when the driving conversion mechanism is replaced by a sleeve, the valve can adapt to the occasion in which the oil inlet and the oil outlet are arranged on the same side, the interchangeability is high, and field pipelines are more flexibly arranged.

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 ...
