Detailed Description
The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.
As shown in fig. 1-5, a valve group control device for a wind turbine generator gearbox lubricating system comprises a valve group jacket 1, a valve sleeve 2, a valve core 3 and an end cover 4, wherein the valve group jacket 1 is coaxially provided with a through hole 5 and one end of the through hole 5 is provided with an internal thread, the valve core 3 is arranged in the valve group jacket 1, one end of the valve sleeve 2 is provided with an external thread and is in threaded connection with the valve group jacket 1, one end of the end cover 4 is provided with a spring 6, the spring 6 penetrates through the valve sleeve 2 to be abutted against the valve core 3, and the end cover 4 is connected with the valve sleeve 2.
As a modification, one end of the valve core 3 far away from the spring 6 is in a conical surface shape.
