The hydraulic valve block is a thicker mounting plate for hydraulic components. The plate hydraulic components are installed on the front of the hydraulic block with thread ,On each side (keep the bottom surface or one surface as the mounting and fixing surface), the corresponding holes on the front are connected with the holes of the hydraulic valve

According to the path requirements of the hydraulic system schematic diagram, longitudinal and transverse holes are drilled inside the oil circuit board, and threads are opened at the holes for installation

The hydraulic fitting is used for connecting pipes.

In order to avoid too long and too many holes that are not easy to process, the number of components installed on an oil circuit board is generally not more than

10-12. The side length of the oil circuit board should not be greater than 400mm.

When the number of holes in the oil passage plate is large and intersects with each other, in order to facilitate the design and manufacture and reduce the process holes

The thickness of the road plate is divided into three layers. The first layer is the channel (L layer) for oil leakage and oil hole control, with a small hole diameter; The second layer is

Pressure oil hole channel (layer P); The third layer is the oil return hole channel (layer O).

If the number of components is not large, arrange the pressure oil hole channel and return oil hole channel in the same layer as far as possible to reduce oil.
