The utility model discloses an imaging agent spraying device for solvent removing type penetrant testing. The imaging agent spraying device comprises two parallel base plates and spraying supports fixedly connected to the base plates, two directed idler wheels are installed on the lower portion of each base plate, the other ends of the two supports are both hinged to or fixedly connected with a pushing handle arranged at the ends of the two supports, an imaging agent spraying drum is connected with the lower portion of the pushing handle through a clamping sleeve, and the pushing handle is perpendicular to a plane formed by the two spraying supports on the two sides. The included angle between the mean line of the included angle of the spraying supports on the two sides and the horizontal plane is 35 degrees. The imaging agent spraying device is simple in structure and convenient to use, and the spraying angle of the imaging agent spraying drum and the distance between an imaging agent spraying nozzle and a tested face can be controlled according to requirements. Based on control over the two parameters including the imaging agent spraying angle and the distance between the imaging agent spraying nozzle and the tested face, standardization operation of the imaging agent spraying link of penetrant testing can be achieved, influences of manual factors are greatly reduced, and the detection sensitivity is stable and controllable.
