Hydraulic valve is a vital control element in hydraulic system, its stable operation is directly related to the performance and safety of the whole system. In order to protect the hydraulic valve from damage and extend its service life, a series of protective measures need to be taken. First, the cleanliness of the hydraulic oil should be ensured, and the hydraulic oil should be replaced and filtered regularly to remove impurities and moisture and prevent them from blocking the spool or corroding the valve body. Secondly, the reasonable design of the hydraulic circuit to avoid hydraulic shock and high pressure peak directly acting on the hydraulic valve can be reduced by installing a buffer device or pressure limiting valve. In addition, it is also necessary to pay attention to the working temperature of the hydraulic valve to avoid overheating leading to the aging of the sealing material or the deformation of the valve body, which can be dealt with by the cooling system or the selection of high temperature resistant materials. Finally, regular inspection and maintenance of the hydraulic valve, including cleaning the valve body, checking the status of the seals, adjusting the position of the spool, etc., timely detection and treatment of potential problems, is the key to ensure the long-term stable operation of the hydraulic valve. In summary, by keeping the hydraulic oil clean, optimizing the hydraulic circuit design, controlling the operating temperature and regular maintenance inspections, the hydraulic valve can be effectively protected to ensure that it can still work reliably under complex and variable working conditions.
