The vortex-like airflow chambers also help to increase the mixing between the air in the duct 23 and the surrounding medium, improving the efficiency and effectiveness of ventilation. By providing the swirl-shaped ventilation duct processing path on the outer circumferential wall surface of the duct 23, a curved path can be formed when the air blown in by the air pump through the ventilation hole passes through the ventilation duct, and eventually a swirl-shaped airflow chamber can be formed when the air is blown into the duct 23. This design makes ventilation effect more even, improves ventilation efficiency, provides important support for the normal operation of wind groove 23.
The working principle is that the device utilizes the combination of high-pressure water flow and abrasive to cut in the operation process. The high-pressure water flow is sprayed out through the spray head 1, and the water flow is converged through the design in the air groove 23, so that the cutting precision is improved. Wherein the abrasive is mixed with the high-speed vortex-like water flow in the abrasive mixing tank 24 and the abrasive is concentrated in the middle of the water flow due to the vortex effect, the high-speed vortex-like water flow ejected through the nozzle 1 can reduce the degree of water flow diffusion at the cutting end when cutting. The vortex-shaped water flow is formed by blowing four inclined air holes on the air groove 23 to the air groove 23, so that a vortex-shaped air flow is formed in the air groove 23, the water flow gradually rotates under the action of the vortex-shaped air flow after the water flow enters the air groove 23, finally the vortex sheets 63 rotate through the four vortex sheets 63 on the vortex piece 6, the water flow reversely acts on the water flow to enable the water flow to flow out from four holes formed by the vortex sheets 63 at a high speed, and the flowing four directions are mutually combined to form a vortex shape, so that the water flow finally rotates at a high speed in the spray head 1, and the water flow in the state can be greatly converged and is not diffused all around, thereby realizing more powerful cutting and higher-precision cutting.
In summary, compared with the nozzle adopted by the traditional water jet cutting, the device is provided with the vortex-shaped air groove 23 and the vortex piece, which can more intensively collect the high-pressure water flow, when the air groove 23 operates, the air groove 23 is communicated with four identical wind speeds in different directions, the inner cavity of the air groove 23 forms a low-pressure environment by matching with the high-pressure high-speed water flow flowing through the pressure nozzle 5, the water flow and the air flow are further concentrated to the center of the air groove 23, and finally form a wind groove cavity similar to a tornado, so that the water flow in the state flows through the vortex piece 6 at the contact end of the air groove 23 to drive the vortex piece 63 on the vortex piece to rotate further, the gaps among the four vortex pieces 63 can be continuously changed in a rotating way, the structure of the vortex piece 63 is similar to the curvature of the turbine piece to conform to the air flow, the water flow flows out of the gaps of the vortex piece 63 and then flows through the high-speed rotation and the driving of the curvature path on the vortex piece 63, and finally the vortex piece 63 reaches the mixed abrasive material 24 to form a complete vortex state;
the installation of vortex piece is through setting up spout and slider cooperation spring 64 use at vortex piece 6 support outer wall for thereby the triangle 62 that is connected with slider 65 upper end can draw in to the center when sliding reduces the excircle diameter of whole vortex piece 6, and in getting into the vortex inslot, the back is pulled back again to the triangle through spring 64 and is made triangle 62 joint in the vortex inslot, realizes the quick installation of vortex piece 6.
