The invention relates to an ultrahigh-pressure exhaust valve comprising a main valve and a trace exhaust valve group. The lower end of the main valve communicates with a pipeline, the main valve is used for achieving large-amount low-pressure exhaust and large-amount air suction, and the main valve comprises a main valve body, a main valve deck installed on the top of the main valve body and provided with a first exhaust hole, a main valve floating ball assembly installed in the main valve body and a throttling exhaust assembly installed on the upper portion of the main valve deck. The trace exhaust valve group is connected with the main valve and is used for achieving high-pressure automatic exhaust. The trace exhaust valve group comprises a trace exhaust valve group valve body, a trace exhaust valve group valve deck, a sealing base and a floating ball lever assembly. The bottom of the trace exhaust valve group valve body communicates with the lower part of the main valve body, and the upper part of the trace exhaust valve group valve body is fixedly connected with the main valve body. The trace exhaust valve group valve deck is arranged on the top of the trace exhaust valve group valve body. The sealing base is arranged on the trace exhaust valve group valve deck and is used for achieving trace exhaust. The floating ball lever assembly is fixed to the trace exhaust valve group valve deck and is used for achieving opening and closing of the sealing base. Compared with the prior art, the ultrahigh-pressure exhaust valve has the advantages of being high in strength, good in sealing performance, capable of preventing overcompression and capable of achieving rapid and stable opening through the eccentric fit lever principle.
