Abstract
The invention provides an air-jet loom spraying nozzle with a rectification air chamber. The air-jet loom spraying nozzle with the rectification air chamber comprises a spraying nozzle pipe body, a weft insertion channel and an annular air chamber formed between the inner wall of the spraying nozzle pipe body and the outer wall of the weft insertion channel, wherein the weft insertion channel is coaxial to the spraying nozzle pipe body and penetrates through the spraying nozzle pipe body from one end of the spraying nozzle pipe body to the other end of the spraying nozzle pipe body. The annular air chamber is communicated with an air inlet channel. The air-jet loom spraying nozzle with the rectification air chamber is characterized by further comprising the rectification air chamber arranged at the rear end of the annular air chamber in the weft insertion direction, the air inlet of the rectification air chamber is communicated with the annular air chamber, and the air outlet of the rectification air chamber is communicated with the weft insertion channel. Because an annular grid-shaped seam formed between an air current guide piece and the rectification air chamber is used for cutting rotational flow coming from the annular air chamber and the large-scale rotational flow is divided into much small-scale rotational flow, the velocity component, perpendicular to the advancing direction, of fluid is weakened, the velocity component in the advancing direction is strengthened, and accordingly the utilization rate of a jet air current is improved.
