Beschreibung
Zusammenfassung:	The invention relates to a built-in hydraulic drive composite cooling high-temperature exhaust valve which comprises a valve seat. The sleeve is arranged outside the valve seat in a sliding manner; the valve core is fixed at the end part of the sleeve; the first cooling plate is arranged in the valve seat and forms a cooling channel with the inner wall of the valve seat; a plurality of first sweating cooling holes; the water inlet and the water outlet are formed in the end, away from the valve element, of the valve seat and communicate with the cooling channel. The sleeve is fixed to an outlet of a combustion chamber, the sleeve is arranged outside the valve seat in a sliding mode, the valve element is fixed to one end of the sleeve and axially moves along with the sleeve, the windward part is inserted into the other end of the sleeve, the first cooling plate is arranged in the sleeve, a cooling channel is formed between the first cooling plate and the sleeve, and first sweating cooling holes are formed in th
