Cartridge Valve Block Set
The cartridge valve block group is a key component in the hydraulic system. It combines the functions of cartridge valves and valve blocks to achieve compact layout and efficient control of the hydraulic system through integrated design. The following is an introduction from the structure, characteristics, application, design points and development trends:
1. Structural composition
The plug-in valve block group is usually composed of plug-in valves, valve blocks (integrated blocks), control cover plates, seals and other parts:
Cartridge valve: As the core control element, functions are realized by inserting the valve block, including directional control valve, pressure control valve, flow control valve, etc.
Valve block: A carrier integrating multiple cartridge valves, with internal processing channels and oil passages, used to connect each cartridge valve and distribute hydraulic oil.
Control cover: Installed on the top of the valve block, it provides a pilot control oil circuit and electrical interface to control the opening and closing of the cartridge valve.
Seal: Ensure the seal between the valve block and the cartridge valve to prevent hydraulic oil leakage.
2. Technical characteristics
Modular design: Through the combination of cartridge valves, a variety of hydraulic functions can be flexibly realized, such as direction control, pressure adjustment, flow distribution, etc.
High degree of integration: Integrate multiple hydraulic valves into the valve block to reduce pipeline connections, reduce leakage risk, and improve system reliability.
Strong versatility: The cartridge valve block set can be adapted to cartridge valves of different specifications, which is convenient for system expansion and maintenance.
Excellent performance: The cartridge valve has fast response speed and high control accuracy, and is suitable for high-pressure and high-flow hydraulic systems.
III. Application areas
The cartridge valve block set is widely used in industrial hydraulic systems, such as:
Construction machinery: hydraulic control system for excavators, cranes, loaders and other equipment.
Metallurgical equipment: hydraulic transmission systems such as rolling mills, continuous casting machines.
Ship and marine engineering: hydraulic systems such as servo, anchor, freighter, etc.
Agricultural machinery: hydraulic drive systems such as tractors and harvesters.
Aerospace: Hydraulic control systems such as aircraft landing gear, flaps, etc.
4. Key points of design
Optimization of valve block layout: According to the hydraulic system schematic diagram, rationally plan the internal channels and oil circuits of valve blocks to reduce pressure losses and leakage risks.
Selection of cartridge valves: Select the appropriate cartridge valve model based on system flow, pressure and other parameters to ensure performance matching.
Sealing design: adopts a reliable sealing structure to prevent hydraulic oil leakage and improve system reliability.
Control logic design: The logic control of the cartridge valve is realized through the control cover plate to meet the system functional needs.
