Abstract
The utility model discloses a high temperature ball valve that floats sealed firmly has mainly solved present high temperature ball valve that floats sealed firmly because thermal energy and arouse easily that rising of spheroid and disk seat dies under high temperature working condition, leads to the problem that the valve can't open. The utility model provides a high temperature ball valve that floats sealed firmly is equipped with sealed complex spheroid and disk seat in its valve body, be connected with the valve rod on the disk seat, still is equipped with sealing filler between disk seat circumference and the valve body, still include with valve body threaded connection's gland, the gland cover is established with disk seat circumference outer wall and is used for compressing tightly a sealing filler, still is equipped with the elastic component between disk seat axial and the disk seat. The metal ball valve that floats sealed has firmly adopted the loaded seal structure of elastic component, and the thermal energy of spare part can be absorbed by the elastic component under high temperature, so it is dead to guarantee that the valve can not risen under high temperature to can open and close in a flexible way under high temperature.
