Problems solved by technology

Common nozzles (such as figure 1 As shown) mainly includes a nozzle body 10, a high-pressure liquid channel 20 is arranged inside the nozzle body 10, and the high-pressure liquid channel 20 includes a circular channel body 21, and the outer end of the circular channel body 21 is provided with a The inclined contraction channel 22' inclined in the direction of the line. During the cutting process of the nozzle with this structure, after the water is sprayed from the nozzle, it will diffuse in an umbrella shape, which will cause a slight inclination angle at the cutting edge, which will affect the cutting quality.

Embodiment 1

[0021] like figure 2 As shown, a concentrating nozzle includes a nozzle body 10, the nozzle body 10 is made of metal, and the nozzle body 10 is integrally formed or welded to effectively ensure that the channels in the nozzle body 10 are firmly connected. ,High pressure. The nozzle body 10 is provided with a high-pressure liquid channel 20 inside, the high-pressure liquid channel 20 includes a circular channel body 21, and the outer end of the circular channel body 21 is provided with a centerline for bending in the direction of the centerline of the circular channel body 21. In order to realize the circular arc channel 22 for primary flow concentration, the diameter of the outer end of the circular arc channel 22 is smaller than the diameter of the circular channel body 21 . The concentrating nozzle of the present invention mainly realizes the concentrating by changing the inclined constricted channel 24 at the outer end of the circular channel body 21 to the arc-shaped arc...

Embodiment 2

[0023] like image 3 As shown in the figure, the structure and principle of this embodiment are basically the same as those of the first embodiment. There is a straight channel 23 that maintains a concentric axis with the circular channel body 21 and is used to extend the converging flow, so that the high-pressure liquid or water flow after converging through the arc channel 22 extends for a period in the straight channel 23 and then ejects Nozzle, effectively ensure the concentration effect after the high-pressure water jet is ejected.

Embodiment 3

[0025] like Figure 4 As shown in the figure, the structure and principle of this embodiment are basically the same as those of the second embodiment. There is a constriction channel 24 inclined to the centerline of the circular channel body 21 for realizing secondary flow concentration. The channel 24 is sprayed out of the nozzle after the secondary flow gathering, which further ensures the flow gathering effect after the high-pressure liquid or water flow is sprayed out of the nozzle, and effectively ensures that the high-pressure liquid or water flow is sprayed through the nozzle and is sprayed to the tissue to be cut in a concentrated flow shape. This ensures cutting quality.

Abstract

The invention discloses a flow gathering nozzle. The flow gathering nozzle comprises a nozzle body; a high-pressure liquid channel is formed in the nozzle body, and includes a circular channel body; an arc channel bent in the center line direction of the circular channel body for realizing once flow gathering is arranged at the outer end part of the circular channel body; and the diameter of the outer end part of the arc channel is smaller than the diameter of the circular channel body. The flow gathering nozzle realizes flow gathering through changing an inclined shrinkage channel at the outer end part of the circular channel body as the arc channel, and has the advantages of simple structure, uniform stress and good flow gathering effect.

Description

technical field [0001] The invention relates to the technical field of nozzles, in particular to a converging nozzle. Background technique [0002] Using the principle of high-speed jet of water or liquid from a micro-hole nozzle, water or liquid can be used as a cutting tool. Common nozzles (such as figure 1 (shown) mainly includes a nozzle body 10, a high-pressure liquid channel 20 is provided inside the nozzle body 10, and the high-pressure liquid channel 20 includes a circular channel body 21. The inclined constriction channel 22' is inclined in the line direction. During the cutting process of the nozzle of this structure, after the water is sprayed from the nozzle, it will spread in an umbrella shape, which will cause a slight inclination angle of the cutting port, which will affect the cutting quality. . SUMMARY OF THE INVENTION [0003] The invention provides a simple structure, the high-pressure water flow has good force effect in the nozzle. After being spraye...
