In hydraulic system design, the design of the integrated valve block is a critical task. The integrated valve block is a complex functional block which is used for installing various hydraulic elements and pipelines and realizing the communication of oil passages among the elements in the integrated valve block according to the requirement of a system principle, and the application of the integrated valve block ensures that the structure of a hydraulic system is more compact and the installation and debugging are more flexible and convenient.
The integrated valve block is used as a bearing carrier of various plate valves, cartridge valves and other accessories, and represents the complexity and the integration level of a hydraulic system. Due to the diversity and nonstandard of functions and components of a common open hydraulic system, the design and manufacture of the open hydraulic system are difficult to realize standardization and modularization. The structure and the function of the closed hydraulic system are relatively fixed, and the standardized and modularized layout is easy to realize.
However, at present, the concept of modular and standardized design is still not adopted for the integrated valve block of the closed hydraulic system in China.
