Basic steps in hydraulic valve block design

Basic steps in the design of a hydraulic manifold:


The design of the hydraulic valve block is to properly place the various valves on all sides of the hydraulic valve block, and determine the communication of the relevant holes according to the hydraulic schematic. These two tasks are carried out in a cross-over manner. When considering the position of the valve, it is necessary to consider the problem of the communication of the holes, and when the arrangement of the holes is arranged, the position of the valve is changed. The hydraulic valve block should be properly arranged in the design of the hole, to minimize the deep hole, inclined hole and process hole, paying special attention to the through hole must have sufficient flow area. The design of the hydraulic valve block is cumbersome, time-consuming and error-prone. The following steps should be taken: (The pressure loss of the oil flowing through the oil passage hole in the block is related to the hole size, shape and smoothness of the oil passage hole. Small, curved, rough inner surface, pressure loss is large; oil passage hole is too large, pressure loss can be reduced, but will increase the shape of the block.)


1. Certification of hydraulic schematics


Before designing the schematic diagram of the hydraulic valve block, the schematic diagram should be carefully examined to ensure that the principle can meet the requirements of the working conditions, and the principle is optimized to minimize the number of components.


2, the choice of components


When selecting a hydraulic valve, be sure to see its pressure and flow range, and pay attention to its pressure and flow curve. If the selection is too small, the pressure loss will be too large, and the system will heat up. If the selection is too large, it will be Cause economic waste. The hydraulic valve is available in two sealing materials (nitrile rubber, fluoro rubber). It is chosen according to the medium actually used. It is best to test the performance of the valve when selecting components.


3, the choice of valve block material


When the working pressure is less than 6.3Mpa, the hydraulic valve block can be cast iron HT200 (good processing performance, especially for deep hole processing, but the strength is not good); working pressure ≥ 6.3Mpa, <21Mpa, hydraulic valve block can be aluminum alloy Forgings; for working pressure ≥ 21MPa, the hydraulic valve block can be selected from forged steel.


4, design


Before designing the schematic diagram of the hydraulic valve block, the schematic diagram should be carefully examined to ensure that the principle can meet the requirements of the working conditions, and the principle is optimized to minimize the number of components. When selecting a hydraulic valve, be sure to see its pressure and flow range, and pay attention to its pressure and flow curve. If the selection is too small, the pressure loss will be too large, and the system will heat up. If the selection is too large, it will be Cause economic waste. The hydraulic valve is available in two sealing materials (nitrile rubber, fluoro rubber). It is chosen according to the medium actually used. It is best to test the performance of the valve when selecting components.
