description The utility model relates to a novel valve oil seal which comprises a rubber body, a framework is vulcanized in the rubber body to form the valve oil seal, a spring groove is formed in an outer shaftneck at the upper end of the valve oil seal, and an oil seal spring is installed in the spring groove. A sealing lip is arranged on the inner side of the upper end of the valve oil seal, and a pressure reducing and temperature reducing lip is arranged on the lower section of the sealing lip to form two lips. Wherein the pressure-reducing and temperature-reducing lip is provided with a recess in the circumferential direction to form an oil storage tank; an automatic centering lip is arranged on the inner side of the rubber body between the sealing lip and the pressure and temperature reducing lip, and a plurality of salient points are uniformly arranged on the automatic centering lip in the circumferential direction, so that the automatic centering lip forms a salient point lip; a bottom seal is arranged on the end
