Abstract:
Multi-position valve and a multi-position valve skid. The multi-position valve comprises an upper valve body, a lower valve body, and a rotary valve core that includes a valve core body and a protruding part and has an oil-directing passageway through the protruding part and the valve core body. The lower valve body has oil inlet passageways through lower end and upper ends. The oil outlet of the oil inlet passageway is on a circle having a radius of the distance from the oil inlet of the oil-directing passageway to its axis, the center of the circle being the axis of the valve core body. When the valve core body rotates, the oil-directing passageway can abut any of the oil inlet passageways. The oil inlet passageways in the multi-position valve run to the lower end of the lower valve body, such that after being connected.
