Hydraulic valve sealing structure suitable for high water-based emulsion

The hydraulic valve sealing structure comprises a valve body, a first valve element is arranged in a valve cavity of the valve body, a first valve sleeve and a second valve sleeve are arranged in the valve body, a second spring seat and a first valve seat are arranged in the first valve sleeve, and a third spring seat and a second valve seat are arranged in the second valve sleeve. The valve element penetrates through the center of the first valve seat and the center of the second valve seat, the end faces, making contact with the valve element, of the first valve seat and the second valve seat are subjected to surface surfacing treatment, and the welding material is soft metal. The two ends of the first valve seat abut against the second spring seat and the valve element tightly at the same time, the first valve seat floats under the action of the second spring seat, it is ensured that the first valve seat and the end face of the valve element are squeezed together all the time, and the position of the valve
