Relevant Weft insertion nozzle and the fluid jet type weaving machine that is used in as the fluid jet type weaving machine of water jet looms of the present invention.
Background technology
As this Weft insertion nozzle, there is so a kind of nozzle to be, to have at its outer peripheral face on the nozzle body of the endless groove that extends along the nozzle-axis direction, insertion has allows the pin of the through hole that weft yarn connects, both form the ring-type stream, make the outer peripheral face of nozzle body chimeric, at a plurality of entrance holes (special fair 4-18053 number) of nozzle body formation with the guiding of the high-pressure fluid in endless groove ring-type stream with nozzle connection with high-pressure fluid supply stream.
In this prior art, high-pressure fluid conflicts with the groove bottom of endless groove from supplying with stream, this right-angle steering along in the endless groove to the spray nozzle front end side shifting, be imported into the ring-type stream by entrance hole, the sinuous flow state that forms is suppressed by the commutator that is disposed at the ring-type stream and flows down, and sprays to Warp opening from the jet that is formed at downstream.
The stream field in ring-type stream downstream (spray nozzle front end side), being made into more downstream, its flow path cross sectional area of side reduces more.Thus, in the stream field of ring-type stream downstream hand hay cutter, its stream alms bowl of side flow is compressed more and quickens more downstream, obtains liberation at jet from compression, sprays to Warp opening.The weft yarn outstanding from the front end of pin contacts with the injection fluid that the blowing loophole sprays, by the conveyance of injection fluid, by picking to Warp opening.
Yet, Weft insertion nozzle in the past, because the inner peripheral surface at nozzle body forms the ring-type stream, having to be formed at the groove bottom diameter of the endless groove of nozzle body outer peripheral face does greatly, the difference in size of outer peripheral face and groove bottom radial direction reduces, thereby reduce the flow path cross sectional area of endless groove, the stream impedance of endless groove must not be constant big, and high-pressure fluid can not pass through at a high speed.Again, conflict with the groove bottom of endless groove from supplying with the high-pressure fluid that stream flows into endless groove, nozzle connection one side that rebounds back, the while becomes the fluid to the spray nozzle front end side at this right-angle steering, advances to entrance hole.Its result, in the Weft insertion nozzle in the past, high-pressure fluid becomes sinuous flow in endless groove, enters the ring-type stream from entrance hole under the sinuous flow state.
As mentioned above, if high-pressure fluid enters the ring-type stream under the sinuous flow state,, can not fully separate the sinuous flow state that disappears even at ring-type flow arrangement commutator.Therefore, in the Weft insertion nozzle in the past, high-pressure fluid can not be quickened in the ring-type stream fully, and simultaneously the injection fluid from jet spreads, and conflicts with warp thread and makes its damage.
The objective of the invention is to, suppress high-pressure fluid and under the sinuous flow state, pass through stream, try to achieve the high speed that sprays fluid.

The specific embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, Weft insertion nozzle 10 comprises: pin 12, coaxially take in the tubular nozzle body 14 of pin 12, coaxially be disposed at ring-type commutator 16 in the nozzle body 14, be assembled into the nozzle connection 18 of nozzle body 14 breakthrough status.
The leading section outer peripheral face of pin 12 has than the little diameter dimension of rearward end outer peripheral face diameter, forms the 1st stream 26 of ring-type again jointly with the inner peripheral surface of nozzle body 14.
The leading section outer peripheral face of the inner peripheral surface of commutator 16 and pin 12 forms the 2nd stream 38 that the past more downstream of flow path cross sectional area reduces more jointly, so that the high-pressure fluid compression is quickened.The 2nd stream 38 has the jet 40 that makes high-pressure fluid be liberated and spray in downstream from the compression of the 2nd stream 38.
Each rectification wall 34 is formed at the upstream side of the 2nd stream 38 of axis direction.The front end blowing loophole 40 of pin 12 is side-prominent downstream.1st, the 2nd stream 26 and 38 has as the compression high-pressure fluid and it is quickened and the effect of the ring-type stream 42 that sprays from jet 40.
Nozzle connection 18 has the supply stream 44 that is communicated with high-pressure fluid source, the outer side slot space 46 that the while has on the through-plane that nozzle body 14 connects and supply stream 44 is communicated with.Between pin 12 and the nozzle body 14, and nozzle body 14 and nozzle connection 18 between, dispose the O type ring 48 more than 1 respectively.
Inner side slot space 30 and outer side slot space 46 are not in the same position on the nozzle-axis direction respectively, and be eccentric and extend on the axis direction of nozzle coaxially, is interconnected under continuous state.
Inner side slot space 30 is by upwardly extending inner side slot bottom surface 50, spray nozzle front end side end face 52 and reversed nozzle front end face 54 form in nozzle-axis side.Spray nozzle front end side end face 52 is inclined to nozzle-axis and converges to reversed nozzle leading section form.
Outer side slot space 46 is by upwardly extending outer side slot bottom surface 56, spray nozzle front end side end face 58 and reversed nozzle front end face 60 form jointly in nozzle-axis side.Supply with stream 44 at outer side slot bottom surface 56 openings.
In the illustrated example, two spray nozzle front end side end faces 52 and 58 are in same position on the nozzle-axis direction, and two reversed nozzle front end face 54 and 60 are in same position on the nozzle-axis direction.Each entrance hole 32 extends to the state with the spray nozzle front end side end face orthogonal in inner side slot space 30, the spray nozzle front end side end opening in inner side slot space 30.
On axis direction, the positions relation that two spray nozzle front end side end faces 52 and 58 form should be: the spray nozzle front end side end face 58 in outer side slot space 46 be in consistent with the spray nozzle front end side end face 52 in inner side slot space 30 local or than it more to the place of reversed nozzle front.
In Weft insertion nozzle 10, high-pressure fluid enters outer side slot space 46 and inner side slot space 30 from the supply stream 44 of high-pressure fluid source through nozzle connection 18.In the Weft insertion nozzle 10, inside and outside two slot spaces 30,46 form the concentrated flow road with big flow path cross sectional area.Compare with Weft insertion nozzle in the past, such concentrated flow road with big flow path cross sectional area, the stream impedance is little, and the pressure loss on its concentrated flow road reduces.Therefore, enter the high-pressure fluid on this concentrated flow road at a high speed by the concentrated flow road.
Again, from supplying with the high-pressure fluid that stream 44 enters two slot spaces 30,46, conflict with the inner side slot bottom surface 50 in inner side slot space 30, nozzle connection one side rebounds back.Yet, owing in Weft insertion nozzle 10, be formed with outer side slot bottom surface 56, and the spaced apart segment distance in two sides, therefore the high-pressure fluid that rebounds back slightly contacts with nozzle connection 18, thereby can not rebound go back to inner side slot bottom surface 50 once more.Therefore, high-pressure fluid can not become sinuous flow in inside and outside slot space 30,46.The high-pressure fluid that conflicts with inner side slot bottom surface 50 enters from supplying with stream 44, and all going up to spray nozzle front end side right-angle steering advanced along axis direction, advances to entrance hole 32 1 sides in inside and outside slot space 30,46.Because entrance hole 32 openings are formed at the spray nozzle front end side end face 52 of the part of inner side slot space 30 spray nozzle front end side ends, high-pressure fluid is directed to spray nozzle front end side end face 52, easily is directed to entrance hole 32.
The part of high-pressure fluid is conflicted with the spray nozzle front end side end face 58 in outer side slot space 46.Yet, in Weft insertion nozzle 10, because the position of two spray nozzle front end side end faces 52 on axis direction and 58 relation is configured to: make the spray nozzle front end side end face 58 in outer side slot space 46 be in consistent with the spray nozzle front end side end face 52 in inner side slot space 30 local or than it more to the place of reversed nozzle front, add that entrance hole 32 is opened on the spray nozzle front end side end in inner side slot space 30, with the high-pressure fluid after the spray nozzle front end side end face 58 in outer side slot space 46 conflicts, can not flow to the anti-front of nozzle, and can flow to entrance hole 32 at once.Therefore, can prevent because of near the 46 spray nozzle front end side ends of outer side slot space, fluid that flows to the spray nozzle front end side and the stream stream that the flows to anti-front sinuous flow that conflicts and take place.
Enter the high-pressure fluid in outer side slot space 46 and inner side slot space 30, enter ring-type stream 42, be imported into the 1st stream 26, be imported into the 2nd stream 38 from the 1st stream 26 from inner side slot space 30 through a plurality of introducing ports 34.Import the high-pressure fluid of the 2nd stream 38, in the 2nd stream 38 that flow path cross sectional area reduces more toward the downstream more, be compressed and quicken, at jet 40 places that are formed at downstream, from the compression of the 2nd stream 38, obtain liberation, and spray from jet 40 as spraying fluid.
Aforesaid result adopts Weft insertion nozzle 10, compares technology in the past, and the high-pressure spray physical efficiency sinuous flow state does not take place and enters ring-type stream 42 at a high speed, becomes high speed and have the well injection fluid of bringing together property in ring-type stream 42.
With reference to Fig. 4, in the Weft insertion nozzle 60, nozzle body 14 is assembled in nozzle connection 62, and the inner side slot space 30 of outer side slot space 64 relative nozzle bodies 14 that makes nozzle connection 62 is to supplying with the stream 44 lateral deviation hearts.
Outer side slot space 46 is formed jointly by the outer side slot bottom surface 66 of extending to the nozzle-axis direction and spray nozzle front end side end face 68 and reversed nozzle front end face 70.
Outer side slot space 46 is in same position with inner side slot space 30 on the nozzle-axis direction, inner side slot space 30 to supplying with the stream 44 lateral deviation hearts, is extended along the nozzle-axis direction, is communicated with inner side slot space 30.
In another Weft insertion nozzle 60, high-pressure fluid enters inside and outside slot space 30,64 from supplying with stream 44.Inside and outside slot space 30,64 is compared with conventional art, because form the concentrated flow road with big flow path cross sectional area jointly, thereby the pressure loss that the stream impedance on its concentrated flow road reduces on its concentrated flow road reduces.Its as a result high-pressure fluid at a high speed by inside and outside slot space 30,64.
From supplying with the high-pressure fluid that stream 44 enters inside and outside slot space 30,46, conflict with the inner side slot bottom surface 50 in inner side slot space 30, nozzle connection 62 sides rebound back.Yet, because in Weft insertion nozzle 60, outer side slot bottom surface 66 relative inner slot spaces 50 are to supplying with the stream 44 lateral deviation hearts, inside and outside groove bottom 30,66 separates a bigger segment distance at the supply flow trackside, so the high-pressure fluid that rebounds back slightly contacts with outer side slot bottom surface 66, thereby can not rebound go back to inner side slot bottom surface 50 once more.Therefore, high-pressure fluid can not become sinuous flow in inside and outside slot space 30,46, in inside and outside slot space 30,64, enter ring-type stream 42.
Its result adopts Weft insertion nozzle 10, compares technology in the past, and high-pressure fluid also the sinuous flow state can not take place and enter ring-type stream 42 at a high speed, becomes high speed and has the well injection fluid of bringing together property.
With reference to Fig. 5 and Fig. 6, fluid jet type weaving machine 80 is the frames (not shown) that a plurality of Weft insertion nozzles 60 are assembled in loom by nozzle holder 82, common nozzle bracket 84 and screw part 86.Each Weft insertion nozzle 60 is that a kind of outer side slot bottom surface 66 relative inner slot spaces 50 are to the nozzle shown in Figure 4 of supplying with the stream 44 lateral deviation hearts.Each is supplied with stream 44 and is connected in high-pressure fluid source by flexible pipe 88.
Two Weft insertion nozzles 60 do not make the eccentric direction unanimity of outer side slot bottom surface 66 relative inner slot spaces 50, but it is configured to nozzle-axis state near each other, the supply stream 44 of the Weft insertion nozzle 60 of one of them is stretched along the vertical direction, and the supply stream 44 that makes another Weft insertion nozzle 60 along about the stretching, extension of (front and back of loom promptly) direction.
As mentioned above, make outer side slot bottom surface 66 relative inner slot spaces 50 in the loom 80 of a plurality of nozzles 60 of supplying with the stream 44 lateral deviation hearts having, except supplying with stream 44 sides, nozzle connection 82 is little because of imaginary radius of a circle direction size around the nozzle-axis, the position of Weft insertion nozzle 60 mutual chien shih supply flow roads 44 sides by adjacency forms different directions, a plurality of Weft insertion nozzles 60 that have outer side slot space 64 on the nozzle connection 62 can be configured to state near each other.
