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:
The present invention relates to a kind of loom parts, particularly relate to a kind of high speed streamline auxiliary nozzle.
Background technology:
Along with development of technology, the field shuttleless loom of weaving full substitution fly-shuttle loom.And in gripper shuttle loom, water jet looms, Rapier looms and the air-jet loom, the excellent again performance of air-jet loom becomes development in future trend.Air-jet loom is finished the wefting insertion process by air-flow, generally adopts the mode of main burner+pilot jet+special-shaped reed at present.Nearly 75% be compressed-air actuated consumption in the energy consumption of air-jet loom according to statistics, therefore how reducing compressed-air actuated consumption reaches the focus that the air-jet loom purpose of energy saving becomes current research.
At present, research in this respect both at home and abroad mainly concentrates in the improvement of pilot jet jet pipe, such as its planform, surface treatment and Performance Detection etc., its purpose all is in order to improve the air flow jetting speed of pilot jet, thereby reduces compressed air consumption.But adopt these measures to reach when improving air flow jetting speed, tend to bring some other negative effect, the most direct is exactly the raising of jet pipe manufacture difficulty and cost of manufacture, and pilot jet service life often be not very long, thereby directly caused whole raising of weaving cost.
Pilot jet mainly is made up of jet pipe and round buss two parts, and wherein jet pipe is generally stainless steel material, and domestic manufacturing technique generally adopts Sheet Metal Forming Technology and the electric spark technology that fans the air, comparatively speaking the improvement of its manufacturing technique difficulty relatively.
The round buss inner chamber of tradition pilot jet all adopts cylindrical structural, is divided into three parts, and mid portion internal diameter minimum forms protruding step, is convenient to the installation of jet pipe, as shown in Figure 1.But, air-flow reflection and disorderly phenomenon that cylindrical structural is easy to generate.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of high speed streamline auxiliary nozzle, to solve the deficiencies in the prior art or defective, meets the demands of production and living.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of high speed streamline auxiliary nozzle, comprise jet pipe 1 and round buss 2, described round buss 2 comprises first section I, second section II, the 3rd section III, it is characterized in that: the inner chamber of the 3rd section III of described round buss 2 is coniform, first section I, the inner chamber of second section II is cylindric, in first section I, establish conical guide duct 3, the internal chamber wall of described the 3rd section III, the internal chamber wall of second section II, the seamless link successively of the wall of guide duct 3, the internal chamber wall of first section I and second section II internal chamber wall, the seamless link successively of the wall of guide duct 3.
As optimized technical scheme: each section junction of round buss inner chamber is a smooth excessiveness, forms a streamline structure.
The intracavity diameter a of 2 first sections I of round buss is 4 ± 0.01mm, the intracavity diameter b of 2 second sections II of round buss is 3.5mm, the inner chamber maximum gauge c of the 3rd section III of round buss 2 is 8-0.036mm, the minimum diameter d of guide duct 3 is 2.5 ± 0.5mm, the length e of first section I is 14.5 ± 0.05mm, the length f of second section II is 3.5mm, and the length of the 3rd section III is that g is 15-0.8mm.
The inner chamber of the 3rd section III of described round buss 2 is the normal cone shape; Guide duct 3 is a normal cone shape.
The invention has the beneficial effects as follows: the present invention helps the injection of air-flow, air-flow reflection and disorderly phenomenon can not occur.
