Valve rod of acting valve

A valve rod of an acting valve comprises a valve rod body, one end face of the valve rod body is provided with an oil duct in the axial direction, two or more combined angle oil-passing holes communicating with the outside are connected to an outlet of the oil duct, a first included angle is formed between the axes of the combined angle oil-passing holes and the axis of the oil duct in the Y direction, and a second included angle is formed between the axes of the combined angle oil-passing holes and the axis of the oil duct in the X direction. When the acting valve performs the separating/combining action, the valve rod body moves in the axial direction under the differential pressure action, fluid passes through the combined angle oil-passing holes under the action of pressure, angular component force is generated for the valve rod body, and then the valve rod body can move forwards spirally. Meanwhile, the fluid passing through the combined angle oil-passing holes forms a vortex, andturbulence is avoided. The speed and stability of the axial motion process of the valve rod body can be improved under the combined action of rotation of the valve rod body and the fluid vortex. Onlythe non-fit dimension of the valve rod body is changed, neither the assembly relation nor other components are affected, and the valve rod of the acting valve is small in design difficulty, simple instructure, easy to machine and free of maintenance.
