The floater type one-way valve comprises a retarder shell, a floater, an air release valve body, a metal filter screen, an oil absorption felt and a dustproof blanking cap. The floater is of a hemispherical structure and installed in a cavity of the retarder shell, and the bottom of the retarder shell is communicated with the retarder working cavity. A floater positioning conical surface is arranged in the cavity of the retarder shell and is used for positioning the bottom of the floater; the vent valve body is mounted at the top of the floater and is hermetically connected with the inner wall of the retarder shell; a matching surface of the inner wall of the vent valve body and the top of the floater is a floater positioning inclined surface for limiting the top of the floater; a metal filter screen is arranged outside the vent valve body, and an oil absorption felt covers the metal filter screen; the dustproof blanking cap is fixed to the outermost portion, and vent holes are formed in the side direction of the dustproof blanking cap. The floater is accurate in positioning, good in oil-gas separation effect and convenient to install and maintain.
