The hard sealing structure of is as follows:
Hard seal high temperatureglobe valveIt consists of valve body, ball, valve stem, metal valve seat and flexible graphite seal ringform。The two valve seats are inserted into the valve body with the axis of the valve stem as the symmetrical center, and the valve seat slides in the insertion groove of the valve body. The sealing between the valve seat and the valve body is realized by the flexible graphite seal ring.Because the flexible graphite seal ring can be compressed and deformed, under the temperature conditions within the specified range, the high-temperature ball valve will not be stuck due to the thermal expansion of the ball, and its temperature cannot exceed 343 ℃.
