[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-Figure 4 A multi-way reversing valve for a hydraulic system comprises a valve body 1, a pressure relief valve 2 is arranged on the side of the valve body 1, an inlet 3 and an outlet 4 are arranged on the top of the valve body 1, an operating rod 5 is connected to the surface of the valve body 1, and an adjusting assembly is arranged on the surface of the operating rod 5; the interior of the adjusting assembly comprises a connecting pipe 6 and an annular plate 7 movably arranged on the surface of the operating rod 5; fixed plates 8 are connected to the two sides of the annular plate 7 respectively, a movable shaft 9 is arranged between the two fixed plates 8, and an adjusting rod 10 is connected to the surface of the movable shaft 9, the adjusting rod 10 can be driven to move on the surface of the operating rod 5 through the connecting pipe 6 and the annular plate 7, so as to adjust the height of the adjusting rod 10, and the adjusting rod 10 can be rotated through the movable shaft 9, so as to adjust the angle of the adjusting rod 10, so as to facilitate use by different personnel.

[0029] Furthermore, a reel 11 for labeling is provided on the surface of the adjusting rod 10, which is convenient for sticking corresponding operation labels on the surface of the reel 11 on the corresponding adjusting rod 10, so as to facilitate operation by novices and avoid operational errors by novices.

[0030] Furthermore, the connecting tube 6 and the annular plate 7 are fixedly connected, and the connecting tube 6 and the operating rod 5 are connected by bolts, which is convenient for adjusting the position of the adjusting rod 10 by moving the connecting tube 6 and the annular plate 7, so as to facilitate the use of different personnel. Of course, the height adjustment distance of the adjusting rod 10 is limited. The surfaces of the connecting tube 6, the annular plate 7 and the operating rod 5 are slidably connected, and the surface of the operating rod 5 is equidistantly provided with threaded holes. After moving the connecting tube 6, the annular plate 7 and the adjusting rod 10 to the specified position, the connecting tube 6 and the corresponding threaded holes on the operating rod 5 can be connected by bolts passing through the connecting tube 6, so as to limit the position.

[0031] Furthermore, positioning holes 801 are equidistantly arranged in an annular manner on the surface of the fixing plate 8, grooves 1001 are provided on both sides of the adjusting rod 10, and springs 1002 are arranged inside the grooves 1001, and a positioning rod 1003 is connected to one side of the spring 1002.
