Abstract
The invention discloses a jet needle for a water jet loom. The jet needle for the water jet loom comprises a jet needle body, the front of the jet needle body is provided with a streamline nozzle, the rear of the jet needle body is provided with a rear cover, and the middle of the jet needle body is provided with an O-shaped seal ring. The jet needle body is provided with an inner conical thread hole for thread to penetrate through, the streamline nozzle is provided with a thread, the front of the streamline nozzle is in threaded connection with a wear-resistant ceramic part, the rear cover is provided with a threaded hole, a wear-resistant ceramic ring is arranged in the threaded hole of the rear cover, the outer wall of the wear-resistant ceramic ring is provided with a thread, and the wear-resistant ceramic ring is provided with a hexagonal thread inlet hole. By means of the wear-resistant ceramic part and the wear-resistant ceramic ring, the service life of the jet needle is greatly prolonged. Further, since the wear-resistant ceramic part and the wear-resistant ceramic ring are both in threaded connection with the jet needle, and the wear-resistant ceramic ring is provided with the hexagonal thread inlet hole, mounting, demounting and replacement are facilitated, and the service life of the jet needle is further prolonged.
Description
Technical field
The present invention relates to a kind of water jet looms nozzle needle, particularly a kind of long service life, and can change the water jet looms nozzle needle of wear-resisting porcelain spare, belong to the Weaving device technical field.
Background technology
Weaving machine with water spraying is a kind of modern shuttle-free loom, and the instantaneous negative pressure that produces when it utilizes water to spray at a high speed makes the ejection of the silk thread of weaving cotton cloth (parallel) high-speed straight-line to replace traditional Weaving shuttle.Nozzle needle is one of critical component of weaving machine with water spraying, and the water spray cover of it and weaving machine with water spraying is worked in coordination and produced instantaneous negative pressure and make the silk thread high-speed straight-line ejection of passing nozzle needle and warp for no reason be woven into cloth.Nozzle needle of the prior art is conical, and the front portion is streamlined nozzle, and the rear portion has the bonnet that has entrance hole, and the middle part has the 0 shape sealing ring of working in coordination with water spray cover inwall, has the taper hole that is used to pass silk thread in the nozzle needle.Spray water in the cover and when nozzle needle nozzle front end sprayed at a high speed, wax was produced instantaneous negative pressure before nozzle when water advances the people, the silk thread of being worn in people's nozzle needle by back entrance hole promptly sprays from nozzle front end high-speed straight-line.Because the frequency and the speed of the logical cable-through hole of silk thread are all very high, the wearing and tearing of entrance hole and line hole front end are all very serious, influenced the service life of nozzle needle.In addition, if after in entrance hole and line hole, being provided with the jewel porcelain eye, owing to can not change, after the jewel porcelain eye damaged, nozzle needle also caused scrapping.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of long service life, and can change the water jet looms nozzle needle of wear-resisting porcelain spare.
Technical solution of the present invention is achieved in that a kind of nozzle needle of water jet looms, comprises the nozzle needle body; The front portion of said nozzle needle body is the cleanliness nozzle; The rear portion of said nozzle needle body is provided with bonnet; The middle part of said nozzle needle body has O-ring seals; Have the taper hole that is used to pass silk thread in the said nozzle needle body; Said cleanliness nozzle is provided with screw thread; Said cleanliness nozzle is preceding through the wear-resisting porcelain spare that is threaded; Said bonnet has screwed hole; Be provided with wear-resisting porcelain circle in the screwed hole of said bonnet: the outer wall of said wear-resisting porcelain circle is provided with screw thread; Said wear-resisting porcelain circle has the hexagon entrance hole.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The nozzle needle of water jet looms of the present invention owing to be provided with wear-resisting porcelain spare and wear-resisting porcelain circle, makes prolong greatly the service life of nozzle needle.Because wear-resisting porcelain spare and wear-resisting porcelain circle all are threaded with nozzle needle, wear-resisting porcelain circle has the hexagon entrance hole again again, and easy disassembly is changed, and has increased the service life of nozzle needle once more.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of the nozzle needle of water jet looms of the present invention;
Accompanying drawing 2 is the exploded view of the nozzle needle of water jet looms of the present invention;
Accompanying drawing 3 is the front section view of the nozzle needle of water jet looms of the present invention;
Wherein: 1, nozzle needle body; 2, cleanliness nozzle; 3, O-ring seals; 4, bonnet; 5, taper hole; 6, screw thread; 7, wear-resisting porcelain spare; 8, screwed hole; 9, wear-resisting porcelain circle; 10, hexagon entrance hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
The nozzle needle of a kind of water jet looms of the present invention shown in accompanying drawing 1-3 comprises nozzle needle body 1; The front portion of said nozzle needle body 1 is a cleanliness nozzle 2; The rear portion of said nozzle needle body 1 is provided with bonnet 4; The middle part of said nozzle needle body 1 has O-ring seals 3; Have the taper hole 5 that is used to pass silk thread in the said nozzle needle body 1; Said cleanliness nozzle 2 is provided with screw thread 6; Before the said cleanliness nozzle 2 through the wear-resisting porcelain spare 7 that is threaded; Said bonnet 4 has screwed hole 8; Be provided with wear-resisting porcelain circle 9 in the screwed hole 8 of said bonnet 4: the outer wall of said wear-resisting porcelain circle 9 is provided with screw thread 6; Said wear-resisting porcelain circle 9 has hexagon entrance hole 10.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The nozzle needle of water jet looms of the present invention owing to be provided with wear-resisting porcelain spare and wear-resisting porcelain circle, makes prolong greatly the service life of nozzle needle.Because wear-resisting porcelain spare and wear-resisting porcelain circle all are threaded with nozzle needle, wear-resisting porcelain circle has the hexagon entrance hole again again, and easy disassembly is changed, and has increased the service life of nozzle needle once more.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
