[0002] The hydraulic valve seat refers to the valve block, which is a very common and very important component in the hydraulic system. It has the characteristics of compact structure, convenient maintenance, installation, adjustment and replacement of hydraulic components. The arc surface of the hydraulic valve seat is generally connected to the surface of the cylinder by welding, and then connected to the hydraulic valve through the mounting hole on one side of the valve seat.

[0003] When the valve seat is not in use, or after the hydraulic valve is removed, the connection holes and threaded mounting holes on the valve seat are exposed to the outside, and a large amount of dust will accumulate over a long period of time. When exposed to the outside, water may enter. In severe cases, the connection holes and threaded mounting holes may be oxidized. Therefore, the protection is poor. For this reason, we propose a hydraulic valve seat assembly with a positioning ear block to solve the above problems. Utility Model Content
