[0002] Magnetic particle testing utilizes the fact that after ferromagnetic materials are magnetized, the presence of discontinuities causes local distortion of the magnetic lines of force on and near the workpiece surface, generating a leakage magnetic field (i.e., the magnetic field formed when the magnetic induction lines leave and enter the surface). This magnetic field attracts the magnetic powder applied to the workpiece surface, forming magnetic marks that are visually visible under appropriate lighting, thereby showing the location, shape, and size of the discontinuity. A spray device is required to spray the magnetic powder.

[0003] Patent document CN216900359U discloses a spray mechanism of a magnetic particle inspection machine, which discloses that "the arched spray pipe is provided with two rows of spray holes, each arched spray pipe will form a spray belt, the spray area is increased, and each workpiece takes about 4 seconds, saving the spraying operation time."

[0004] However, the spray mechanism of the above-mentioned public document mainly considers how to save working time. However, the spray mechanism is equipped with multiple nozzles. If the workpiece is small, it will cause waste of magnetic powder and cannot be accurately applied to workpieces of different sizes.

[0005] In view of this, it is necessary to develop a spray device for a three-way magnetic particle flaw detector, which can change the number of nozzles used according to the size of the workpiece to avoid wasting magnetic powder. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, since the mounting tube is connected to the fixed tube, the magnetic powder in the fixed tube is finally sprayed onto the workpiece through the nozzle. Since each mounting tube is equipped with a solenoid valve, and each solenoid valve is independently connected to the controller, the controller can individually control the switch of each solenoid valve, so that the magnetic powder can be sprayed from which nozzle according to needs. When processing a small workpiece, it is only necessary to open the nozzle corresponding to the top of the workpiece, thereby effectively avoiding the waste of magnetic powder.

[0026] The mounting frame 6 provides a location for the installation of the spray assembly.

At the same time, the bottom of the mounting shell 15 can slide inside the movable groove 20 through the limiting slider 18, thereby changing the use position of the spray assembly, so that the spray assembly can be installed on the flaw detector for more flexible use. The two sides of the limiting slider 18 are limited by connecting with the limiting groove 22, and the front and back are limited by the rotation of the limiting screw 23. When fixed, one end of the limiting screw 23 will enter the fixing hole 19 to ensure the stability of the limiting slider 18.
