Abstract
The utility model relates to the technical field of valves, particularly to a high-speed heavy-duty straight-line reciprocating-operation buffering reversing valve, which comprises a valve seat and a valve core, wherein an oil cylinder cavity is formed in the valve seat; the valve core is arranged in the oil cylinder cavity in a sliding manner; and through oil grooves are formed on the surface of the valve core; buffering angle inclined surfaces are formed on two sides of each through oil groove respectively. The through oil grooves are in smooth transition with the surface of the valve core through the buffering angle inclined surfaces; the percussive action of the high-pressure liquid on a working and moving body when the high-speed switching of the valve core is interrupted instantly can be reduced during the direction changing process of the valve through the buffering angle inclined surfaces on the two sides of the through oil grooves, so that the buffering angle inclined surfaces play roles of buffering and damping in the high-speed reciprocating direction changing for the working and moving body, and avoid the shock of the working and moving body; and the direction change is smooth, the performance is reliable, and the stability and the service life of the valve as well as each working and moving body are improved.
