Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as Figure 2 to Figure 4 As shown, a shell protection structure of an electro-hydraulic servo valve includes an upper cover 1, S-7 polysulfide rubber 2, a valve body 3, a cover plate 4, polyurethane sealant 5, screws 6, shielding wire 7, and sealant 8 . The shielding wire 7 enters through the threading hole on the side of the valve body 3 and passes upward through the outlet hole on the upper surface of the valve body 3, and is welded and connected with the lead wire of the motor coil. The threading hole is filled with polyurethane sealant 5, and the cover plate 4 is fixedly connected with fasteners; After high-temperature aging treatment, the protective structure of the entire electro-hydraulic servo valve shell is formed.
[0021] The processing method of the improved structure of the present invention is as follows:
[0022] Pass the ...
