Abstract
Disclosed herein is a distribution valve for concrete transport pump including: a valve body, rocker arm, end covers, a left rotary valve and a right rotary valve. The end covers are disposed on two ends of the valve body. The internal space of the valve body is divided into a left valve chamber and a right valve chamber, with the left rotary valve and the right rotary valve being accommodated respectively in the left valve chamber and the right valve chamber. Inlet ports, intake ports and discharge ports are correspondingly provided in the left valve chamber and the right valve chamber of the valve body respectively. The left rotary valve and the right rotary valve are respectively connected with the rocker arm provided outside of two ends of the valve body through a rotary shaft. Both the left rotary valve and the right rotary valve have a cylindrical shape. Through holes, which communicate the inlet ports to the intake ports or communicate the intake ports to the discharge ports, are provided respectively on the cylindrical surfaces of the left rotary valve and the right rotary valve. The distribution valve for concrete transport pump has a superior intake performance and may achieve a high pressure pumping.
