Zusammenfassung:	The utility model discloses a valve body of a hot-end EGR valve. The valve body of the hot-end EGR valve comprises an EGR valve main body (1). A cooling liquid channel (1.1) is formed in a shell of the EGR valve main body (1) in the circumferential direction and performs cooling protection on the EGR valve main body (1). An exhaust pipe (3) is arranged at the position, close to a motor (2), of the wall of the EGR valve main body (1), used for exhausting gas to the outside and communicated with the cooling liquid channel (1.1). The valve body of the hot-end EGR valve is good in cooling effect, boiling bubbles of cooling liquid can be discharged in time, and working is more reliable.
