Función de las 6 superficies de los bloques de distribución hidráulica

Conventional hydraulic manifold blocks, generally a hexahedron, that is, the existence of six surfaces, we today according to the general valve block design method to see the role of the six surfaces of the valve block.

Manifold blocks top and bottom surfaces

The valve block mainly has superimposed joint surfaces on its top and bottom. The surfaces feature a common pressure oil port (P), a common return port (T), a leakage oil port (L), and four fixed bolt holes.

Manifold blocks right side

Generally, one often needs to adjust the components installed on the right side. For instance, within the category of pressure control valves are relief valves, pressure reducing valves, and sequence valves. Similarly, within the flow control valve category are throttle valves and speed control valves. These valves require frequent adjustments during hydraulic system operations. Therefore, we position these components on the right side of the panel to facilitate easier adjustment with the right hand, considering that left-handed individuals are less common.

Manifold blocks front side

When there are many pressure control valves and flow control valves, arranging them all on the right side becomes impractical. Therefore, we arrange some of these valves that need frequent adjustment on the front side as well, as the front side is more convenient to operate.

rear side

We designate the rear side, which is the least accessible, for solenoid valves, check valves, and other valves that do not require manual adjustment.

left side

We usually set the output port for connecting the actuator on the left side.
In addition, we know that we can combine not only hydraulic valves but also accessories like accumulators, pressure gauges, and filters with the integrated block. Therefore, we leave some external pressure ports, accumulator connection ports, and pressure relay ports on the left side of the spare oil port.
Generally, the reserved pressure measurement port will be equipped with a pressure measurement connector, whose thread is usually M14X1.5 or G1/4 pipe thread. In fact, the more pressure measurement points, for troubleshooting is very helpful, but the processing cost will inevitably increase. Therefore, if we use the same specification of threaded plugs for the process holes on the same valve block, we can open fewer pressure measurement ports. When needed, we can use the process holes directly as pressure measurement ports.

summarize

Of course, the layout described above are in the shape, size are not limited to the ideal situation to say. When it comes to the actual design process, I believe many people won’t adhere strictly to the above methods for layout. This is primarily due to various size limitations that prevent the use of unified layout rules to definitively finalize component arrangements. The practical design process often necessitates constant adjustments.When you’re a novice, you may not grasp layout concepts immediately. However, you can attempt to follow the recommended surface layout initially.
