Zusammenfassung:	The utility model provides a novel manual pressure release valve structure for a valve body. The novel manual pressure release valve structure for the valve body comprises the valve body and a stop structure installed on the valve body, a first channel, a second channel and a third channel are arranged in the valve body, the first channel and the second channel are communicated with the outside, the inner diameter of the second channel is smaller than that of the first channel, and the third channel is communicated with the second channel. A cavity defined by the inner surface of the valve body, the cavity wall of the first channel, the cavity wall of the second channel and the cavity wall of the third channel forms a liquid storage cavity, the third channel communicates with the liquid storage cavity, and the stop structure is installed in the first channel. The novel manual pressure release valve structure for the valve body plays a pressure release role in a hydraulic system, in addition, the manual pressu
