1.    The valve disc is connected with the stem by rhombic-heterotypic hole. It maintains the biggest intrinsic capacity of the stem without enlarging its diameter.
2.    In order to eliminate the disc displacing because of its self-weight, we take following measures:
A.    Threaded stem connects the upper stem and the lower stem through by the combined supporting set of the disc. This structure makes the two stems and disc a team.
B.    The hole of the lower stem has the structure like steps, and settled with combined supporting set to prop the disc.
C.    There is a check bearing between the stem and the back end cover, which can efficiently eliminate the friction aroused by the disc and the stem weight, and also can make up for the gap.
