Abstract: The balance valve was the core component in the hydraulic lifting system of construction machinery, which had a significant impact on the stability of the system.A numerical simulation study was carried out for a certain type of balance valve, which caused the deformation of the valve core due to the throttling temperature rise. Firstly, the 3D models of the valve with different opening degrees were established using SolidWorks software. Then ICEM was used to mesh the balance valve.Finally, the ANSYS Workbench platform was used to simulate the balance valve under different working conditions, and the fluid velocity, temperature change and valve core deformation in the flow field of the balance valve under different opening degrees and different inlet and outlet pressure differences were analyzed.The research results show that the temperature in the area close to the orifice is higher, and the temperature in the area away from the orifice is lower.When the valve opening and pressure difference are different, the temperature of the fluid in the valve changes obviously, up to 429K. The temperature distribution of the valve core and the fluid in the valve is uneven, and the valve core has a large local deformation under the influence of temperature, and the maximum deformation amount is 2.28μm, which may lead to the occurrence of the valve core stuck phenomenon.
Key words: hydraulic lifting system; flow control valve; internal flow field analysis; fluid temperature rise; thermal deformation of valve core; stuck of valve core
