英文摘要	The invention relates to a hydraulic valve in the field of hydraulic transmission and control technology, and particularly to a compact type external controlled direct relief valve. The compact type external controlled direct relief valve comprises a valve body, a sealing plug, a valve core, a spring and a block; the valve body is an outer shell of the external controlled direct relief valve, and multiple connecting channels interconnected with an executing element are arranged on the valve body along the axial direction; a hole way is arranged in the valve body, the sealing plug and the block are respectively in sealing connection to both ends of the valve body; the valve core is held in the hole way, and abutted the inner wall of the hole way in the manner of sealing; the hole way between the block and the valve core is a P cavity, a T cavity is arranged on the valve core, an A cavity is arranged on the sealing plug, and three cavities are respectively corresponding to the connecting channels; the spring is arranged in the P cavity, both ends of the spring are respectively abutted to one end of each of the block and the valve core, and the other end of the valve core is abutted with the sealing plug in the manner of sealing; the valve body can be glided along the axial direction of the hole way, so that the middle between the A cavity and the T cavity can be closed or interconnected. The compact type external controlled direct relief valve is stable in performance, compact in structure, low in cost, and easy to realize, and so on.
