Abstract
The invention discloses a concrete pump reversing valve. The concrete pump reversing valve comprises a valve canister. A top cover and a bottom cover are respectively connected with two ends of the valve canister. A revolving shaft is installed inside and outside the center of the top cover in a communicating mode. A revolving valve core of clearance fit of the valve canister is installed at the inner end of the revolving shaft. An installing connecting sleeve is arranged at the outer end of the revolving shaft. A straight line crossing oil groove is arranged from the center to the inner side of a side wall in the bottom surface of the valve core. A C-shaped oil groove around the straight line crossing oil groove is arranged in bottom surface of the valve core. An oil supply hole corresponding to the inner end of the straight line oil groove is arranged in the center of the bottom cover. An oil return hole corresponding to the outer end of the straight line oil groove is arranged in the bottom cover. Two symmetrical oil-taking conversion holes corresponding to the two ends of the C-shaped oil groove are arranged in the bottom cover. At least three bolts are arranged symmetrically from the top cover to the bottom cover through a valve canister wall in a screw joint mode. By means of the concrete pump reversing valve, a hydraulic pressure manipulating mechanism controlled by electricity is replaced by a machinery reversing valve. The concrete pump reversing valve has the advantages of being simple in structure, low in cost, safe and reliable in use.
