Problems solved by technology

[0004] However, since the two-position five-way electromagnetic directional valve is connected to the outer wall of the valve body, when the two-position five-way electromagnetic directional valve is assembled on the valve body, not only the relationship between the two-position five-way electromagnetic directional valve and the valve body needs to be considered. At the same time, the connection relationship between the oil passage in the two-position five-way electromagnetic reversing valve and the oil passage inside the valve body should also be considered, which will make the assembly of the hydraulic control device of the electro-hydraulic ball valve cumbersome.

Abstract

The invention provides a hydraulic control device of an electro-hydraulic ball valve, and belongs to the field of ball valve control. The hydraulic control device comprises a switching valve and a two-position four-way reversing valve, the switching valve comprises a valve body and a core body, the core body is rotatably located in the valve body, the axial direction of a rotating shaft of the core body is the length direction of the core body, and the core body is configured to rotate between a first position and a second position; the two-position four-way reversing valve is mounted on the valve body, and two working oil ports of the two-position four-way reversing valve are respectively communicated with an oil inlet and an oil outlet of the driving component; the first oil supply channel, the second oil supply channel and the third oil supply channel are isolated from one another. According to the hydraulic control device, the structure of the hydraulic control device can be simplified.

Description

technical field [0001] The disclosure belongs to the field of ball valve control, in particular to a hydraulic control device for an electro-hydraulic ball valve. Background technique [0002] The electro-hydraulic ball valve is a valve driven by the valve stem and rotates around the axis of the ball valve. It is suitable for straight-through switching elements in water, gas and oil circuits. The electro-hydraulic ball valve has three operating modes: electric operation, hydraulic manual operation and emergency manual operation. The electro-hydraulic ball valve has a hydraulic control device that can switch the working mode of the electro-hydraulic ball valve. [0003] In the related art, the hydraulic control device includes a two-position four-way reversing valve, a two-position five-way reversing valve and a valve body. The two-position four-way reversing valve and the two-position five-way reversing valve are respectively connected with the outer wall of the valve body...
