Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a high-pressure and low-frequency self-oscillating pulse gas-liquid jet nozzle. Background Art

[0002] The main application forms of high-pressure water jet nozzles are high-pressure abrasive water cutting nozzles, high-pressure pure water cutting nozzles and high-pressure cleaning nozzles. High-pressure water jet nozzles are precisely assembled from stainless steel nozzles and red and blue sapphire sheets. Because the gem material has high hardness and excellent wear resistance, it can extend the service life of the nozzle. At the same time, the gem material has good thermal conductivity and can protect the components from damage.

Since the external connection thread section and the self-excited oscillation cavity are staggered, it is ensured that the inner diameter of the self-excited oscillation cavity can be enlarged without increasing the wall thickness of the pulse jet nozzle, and a higher pulse effect is obtained compared with the traditional pulse nozzle. However, the patent is not convenient for adjusting the width of the liquid sprayed by the nozzle, which determines the thickness of the spray on the object. Therefore, in view of the above shortcomings, a high-pressure, low-frequency, self-oscillating pulse gas-liquid jet nozzle is proposed. Utility Model Content
