Flow distributor assembly, valve box and plunger pump

Abstract

This disclosure describes a diverter assembly, a valve box, and a plunger pump. The diverter assembly includes a diverter, a first valve body, a second valve body, first valve rubber, and second valve rubber. The diverter includes liquid drainage and inlet holes. The liquid drainage hole is communicated with first and second end surfaces facing away from each other in an axial direction of the diverter, and the liquid inlet hole is communicated with a side surface and the first end surface. The first valve body is configured to block the liquid inlet hole and to communicate a communication hole and the liquid drainage hole. The second valve body is configured to block the liquid drainage hole. The first and second valve rubber is configured to hermetically connect the first valve body and the first end surface, and to seal the second valve body and the second end surface, respectively.
