Method of controlling hydraulic valve to be reversed through electric control system

[0030] Example 1

[0031] Such as Figure 1-Figure 3 As shown, a method for controlling the reversal of a hydraulic valve through an electronic control system of the present invention includes the following steps:

[0032] Step A Installation: Install the mounting block 3 on the end of the valve body 1 that is penetrated by the valve core 2, and install the screw 4 on the end of the valve core 2 that penetrates the valve body 1, and the screw 4 can perform relative to the valve core 2. Rotate independently, the end of the screw 4 away from the valve core 2 is matched with the threaded hole and located on the side of the threaded hole away from the valve body 1;

[0033] A comparison block 5 is installed on the side wall of the mounting block 3, and the end of the comparison block 5 far from the valve body 1 is suspended above the screw 4, and on the side wall of the comparison block 5 along the axis of the valve core 2 Set with scale line 6;

[0034] Step B Reversing: Trigger the input

[0037] Example 2

[0038] The present invention is based on Embodiment 1, and further illustrates the present invention.

[0039] Such as Figure 1-Figure 3 As shown, the present invention is a method for controlling the reversal of a hydraulic valve through an electronic control system, and the axis of the threaded hole coincides with the axis of the valve core 2.

[0040] Further, a connecting ring 7 is sleeved on the side of the screw 4 that is away from the valve core 2, and the outer wall of the connecting ring 7 is in contact with the end of the comparison block 5 close to the screw 4. The connecting ring 7 is in contact with the comparison block 5, which is convenient for the user to judge the moving distance of the screw 4 smoothly and accurately.

[0041] Further, the connecting ring 7 is clamped with the screw 4 through a spring stop ring 8. The connecting ring 7 can independently rotate relative to the screw 4, and a guide block 9 is provided on the outer wall of the connecti

[0042] Example 3

[0043] The present invention is based on Embodiment 1, and further illustrates the present invention.

[0044] Such as Figure 1-Figure 3 As shown, the present invention is a method for controlling the reversal of a hydraulic valve through an electronic control system. A connecting block 12 whose axis coincides with the axis of the valve core 2 is provided between the screw 4 and the valve core 2. The connecting block 12 The longitudinal section of is an I-shaped, one end is inserted into the screw 4, and the other end is inserted into the valve core 2. The screw 4 is rotatably connected with the valve core 2 through the connecting block 12.
