The invention provides a detector for a pulser control valve. The detector comprises a pedestal, an elastic force application part, a position detection part and a pressure detection part; the pedestal includes an accommodation part; the elastic force application part is used to apply a preset pressure to the pulser control valve; the position detection part is arranged between the elastic force application part and the pulser control valve, and used to detect the position of the pulser control valve; and the pressure detection part is connected with the position detection part, arranged between the elastic force application part and the pulser control valve, and used to detect a thrust of the pulser control valve. Via technical scheme of the invention, the problem that whether the pulsercontrol valve works normal cannot be determined rapidly and simply by a detector in the prior art is solved.
