description The utility model discloses a low-temperature eccentric hemisphere ball valve which mainly solves the problems that the existing low-temperature ball valves are poor in tightness, complicated in structure and poor in safety performance when used. The centre line of a flow pass and the centre line of an upper valve rod are eccentric and the spherical centre of a valve element and the centre line of the upper valve rod are eccentric. The low-temperature eccentric hemisphere ball valve has the advantages of being simple in structure, convenient to operate, good in sealing performance, and long in service life.
