The present invention relates to an air and hydraulic breaker type valve structure. More specifically, the present invention relates to an air and hydraulic type breaker valve structure installed in a valve room (VR) to convert the flow direction of fluid, wherein the air and hydraulic type breaker valve structure comprises: a valve sleeve inserted and installed in the valve room (VR), wherein both sides of the valve sleeve are opened; a valve spool installed to be movable while being in surface contact with the inside of the valve sleeve (100), wherein both sides of the valve spool are opened; and a valve plug connected to the end of the other side of the valve sleeve. According to the present invention, since the both sides of the valve spool are completely opened, upper and lower operations of the valve are fast and smooth, thereby lowering the hydraulic pulsation due to such a fast valve operating rate. Further, the hydraulic pressure that is put into the valve sleeve is relatively uniformly operated through each stepped face, so that the high-pressure hydraulic pressure applied to the external circumference of the valve spool is relatively symmetrically operated based on the central axis of the valve spool, resulting in reduction in the friction between the external circumferential surface of the valve spool and the inner circumferential surface of the valve sleeve, thereby allowing a smooth sliding motion and reducing wear or scratch due to the friction. |
