Description

Technical Field

[0001] This utility model relates to the field of servo valve technology, and in particular to a novel electro-hydraulic servo valve. Background Technology

[0002] In hydraulic systems, servo valves are key control components, and their performance directly affects the stability and accuracy of the entire system. Traditional hydraulic servo valves have some shortcomings in their structural design, particularly in terms of disassembly, cleaning, and structural connections. These issues limit their application range and efficiency.

[0003] Traditional servo valves have a complex structure and numerous parts, making disassembly and assembly cumbersome. This process is not only time-consuming and labor-intensive, but also prone to damaging components during disassembly and assembly, affecting the valve's performance and service life. Due to their compact structure and complex internal channels, traditional servo valves are difficult to thoroughly clean during cleaning. Long-term accumulation can lead to a decline in valve performance and even cause malfunctions.

[0004] Therefore, we propose a novel electro-hydraulic servo valve. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a new type of electro-hydraulic servo valve.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel electro-hydraulic servo valve, comprising an electro-hydraulic servo valve body, an oil tank disposed below the electro-hydraulic servo valve body, four connecting posts disposed between the bottom of the electro-hydraulic servo valve body and the top of the oil tank, each connecting post having a connector fixedly connected to its top and bottom, each connector having a through-hole mounting screw hole on its outer wall, the bottom of the electro-hydraulic servo valve body and the top of the oil tank having connecting holes near the four corners, each connector being slidably installed in its corresponding connecting hole, threaded mounting holes being provided on the left and right sides of the electro-hydraulic servo valve body near the two lower corners and on the left and right sides of the oil tank near the two upper corners, each threaded mounting hole having a fastening bolt threadedly installed in its threaded mounting hole, the end of each fastening bolt being threadedly connected to its corresponding mounting screw hole, and auxiliary handles fixedly installed in the middle of the left and right sides of the electro-hydraulic servo valve body.

[0007] Furthermore, two oil pipes are provided between the bottom of the main body of the electro-hydraulic servo valve and the top of the oil tank. Connecting threaded heads are fixedly installed at the top and bottom of the two oil pipes, and sealing rubber rings are respectively fitted on the outer walls of the two connecting threaded heads.

[0008] Furthermore, the bottom of the electro-hydraulic servo valve body and the top left and right ends of the oil tank are respectively provided with connecting screw holes, and each connecting thread head is threaded into the corresponding connecting screw hole.

[0009] Furthermore, a drive motor is fixedly installed at the top center of the oil tank.

[0010] Furthermore, mounting rings are fixedly installed inside the two oil pipes.

[0011] Furthermore, filter screens are respectively inserted and installed on the top of the two mounting rings.

[0012] Furthermore, auxiliary pull rings are fixedly installed at the top center of each of the two filter screens.

[0013] This utility model provides a novel electro-hydraulic servo valve. It has the following beneficial effects:

[0014] 1. This new type of electro-hydraulic servo valve, during use, utilizes the interplay between its components, including the valve body, oil tank, connecting column, fastening bolts, auxiliary handle, connector, oil pipe, threaded connector, and sealing ring. When disassembly is required, the operator first loosens all the fastening bolts, then rotates the oil pipe to unscrew the threaded connector from the threaded hole. This allows the valve body and oil tank to be separated, and all connecting columns and oil pipes can be disassembled before proceeding with subsequent operations. The quick disassembly and assembly mechanism simplifies the process, significantly improving work efficiency.

[0015] 2. This new type of electro-hydraulic servo valve, through the cooperation of components such as oil pipes, filter screens, auxiliary pull rings, and mounting rings, effectively prevents impurities in the hydraulic oil from entering the main body of the electro-hydraulic servo valve and affecting the service life of the device. At the same time, the auxiliary pull rings facilitate the removal of the filter screens for cleaning, thus improving practicality.

[0016] 3. This new type of electro-hydraulic servo valve, through the cooperation between its main body, oil tank, auxiliary handle, and other components, allows workers to easily lift and move the device when it needs to be moved, thus improving work efficiency. Attached Figure Description
