Capillary viscometer for liquid filling and auxiliary heating

The utility model discloses a capillary viscometer for liquid filling and auxiliary heating. The capillary viscometer comprises a capillary viscometer body, wherein the capillary viscometer body is arranged in a transparent insulating and heating casing in a sealed manner; a liquid inlet pipe connector and a liquid outlet pipe connector are respectively arranged in upper and lower side walls of the transparent insulating and heating casing; upper openings of a liquid filling pipe, a capillary pipe and an exhaust pipe are sealed and extend out of the top wall of the transparent insulating and heating casing; the upper opening of the liquid filling pipe is of a flared structure, and the lower opening of the liquid filling pipe is provided with a cylindrical liquid accommodating cavity; the first opening of a U-shaped conduit is communicated with the bottom of the cylindrical liquid accommodating cavity, and the second opening of the U-shaped conduit is communicated with the lower openings of the capillary pipe and the exhaust pipe by a communicating cavity. The capillary viscometer has the advantages that the problems of deficiency and liquid filling difficulty caused by mating of a constant-temperature water bath tank when an existing capillary viscometer is used for detecting viscosity can be solved by improving the structure of the existing capillary viscometer, and the capillary viscometer has an especially remarkable effect when used for detected liquid having relatively large viscosity.
