Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic valves, and particularly relates to a hydraulic valve body assembly. Background Art

[0002] Hydraulic valves are components used to control the flow direction, pressure, and flow rate of liquids in hydraulic systems. They play a crucial role in many fields such as industrial machinery and construction equipment. When in use, the hydraulic valve body will be interfered by external forces, such as collisions. Moreover, the extension of the service time of the hydraulic valve will also lead to a decline in the sealing performance. Therefore, oil leakage may occur inside the hydraulic valve. This requires the use of corresponding components to suck and clean the leaked oil to prevent excessive oil leakage from affecting other components. Most of the pipe fittings used for suction are of soft structure. In most cases, the suction pipe fittings are in an idle state. However, the installation area of the hydraulic valve is mostly complex, and it will face collisions with foreign objects and the passing of rodents, etc. This may cause damage to the soft-structured suction pipe fittings. As a result, when subsequent use is required, the damaged suction pipe fittings cannot suck the leaked oil, affecting the normal suction operation, and it takes time to repair them.

[0003] In summary, the lack of protection for the soft suction pipe fittings in the leaked oil of the hydraulic valve body will cause some problems in use. Therefore, it is hoped to propose a new structure to solve the above technical problems. Summary of the Utility Model
