Abstract

The invention disclose a high speed streamline aided injecting nozzle, comprising nozzle 1 and circle sleeving 2, which contains a first segment I, a second segment II and a third segment whose bore is taper. The bores of the first segment I and the second segment II are cylinder. Taper guide pipeline 3 is set in the first segment I. said bore walls of the third segment III, the second segment II and guide pipeline 3, which are seamless, are connected orderly, and the bore walls of the first segment I, the second segment and guide pipeline 3, which are seamless, are connected orderly. The invention is provided with favorable jetting for air flow, no air flow reflection and disorder phenomenon.

Description

Technical field: [0001] The invention relates to a loom component, in particular to a high-speed streamlined auxiliary nozzle. Background technique: [0002] With the advancement of technology, shuttleless looms have completely replaced shuttle looms in the field of weaving. Among projectile looms, water-jet looms, rapier looms and air-jet looms, the excellent performance of air-jet looms has become a future development trend. The air-jet loom completes the weft insertion process through airflow. Currently, the method of main nozzle + auxiliary nozzle + special-shaped reed is generally used. According to statistics, about 75% of the energy consumption of air-jet looms is the consumption of compressed air, so how to reduce the consumption of compressed air to achieve the purpose of energy-saving of air-jet looms has become a hot spot in current research. [0003] At present, domestic and foreign research in this area mainly focuses on the improvement of the auxiliary nozzle...
