The utility model discloses a low damping formula disk seat, it includes rectangle cavity body (1), the rectangle hollow tube is internal to be offered about rectangle cavity body symmetrical upper shed groove (2) and under shed groove (3) in horizontal axis, upper shed groove and under shed inslot adaptation respectively have along pressure spring (4) of rectangle cavity pipe length direction distribution, the adaptation has blotter (5) between the inner wall in pressure spring and upper shed groove and under shed groove, pressure spring outside centre gripping has a plurality of balls (6). The beneficial effects of the utility model are that having provided buffer space when guaranteeing disk seat and valve rod contact, can having carried out the distance between self -adaptation adjustment valve rod and the disk seat according to the operating mode, realized rolling friction through the ball between valve rod and the disk seat, resistance coefficient is little, safeguards the convenience.
