Abstract
The utility model relates to a boiler water circulating pump, in particular to a boiler water circulating pump with a valve rod upper portion retention mechanism. The boiler water circulating pump comprises a support, wherein a valve rod is arranged in the support, a valve rod nut is sleeved on the upper end of the valve rod, the lower end of the valve rod nut is clamped with an inner wall of the support through a lower bearing, and the upper end of the valve rod nut is clamped with an inner wall of the support through an upper bearing. Seal plates are arranged among the upper portion of the upper bearing, the bottom of the lower bearing and the valve rod nut respectively, the outer edges of the seal plates are provided with seal rings sealed with the inner wall of the support, and the seal rings are in embedded connection with the seal plates. The boiler water circulating pump with the valve rod upper portion retention mechanism is simple in structure and remarkable in using effect.
