Abstract
The utility model relates to a stabilized pressure pump sealing structure. The stabilized pressure pump sealing structure comprises piston pushing blocks, a diaphragm sheet and an eccentric wheel assembly which are fastened and connected together through fasteners. The piston pushing blocks are fixedly arranged in a piston moving area of the diaphragm sheet, and the piston pushing blocks are provided with through holes allowing the fasteners to penetrate through. Hollow two-way positioning convex rings are formed in the piston moving area. The hollow two-way positioning convex rings comprise the upper positioning convex ring which protrudes out of the top face of the diaphragm sheet and the lower positioning convex ring which protrudes out of the bottom face of the diaphragm sheet, the upper positioning convex ring is matched with the through holes in the piston pushing blocks, and the lower positioning convex ring is matched with a counter-sink hole sink table on the eccentric wheel assembly. A positioning rib is arranged on the peripheral face of the upper positioning convex ring, and a positioning groove which is in close fit with the positioning rib is formed around an eccentric hole. Due to the fact that the positioning rib and the positioning groove which are in close fit are additionally arranged, even though water pressure is large, gaps allowing water flow to pass through cannot be produced easily among the diaphragm sheet, the piston pushing blocks and the fasteners. A water hammer resistance test and a durability test prove that normal operation of a stabilized pressure pump can be effectively guaranteed through the structure.
