Description
Technical field
The utility model relates to a kind of air stream decetor, relates in particular to a kind of being applied in and is used for the on-the-spot air stream decetor that detects the pilot jet performance on the air-jet loom.
Technical field
Air-jet loom utilizes jet-stream wind as the wefting insertion carrier, and jet-stream wind is drawing weft yarn and leaping reed width, and the function of pilot jet is exactly to produce jet-stream wind under the pressure of regulation.The loom rotating speed is more and more higher, and the weft yarn flying speed also must improve, and the air-flow velocity that pilot jet sprays must be greater than the weft yarn flying speed.In the use of air-jet loom, the pilot jet inner chamber can part stop up, and air-flow is current not smooth; In the opening process, pilot jet is walked up and down at thread layer, and the tube wall of pilot jet spray-hole is because of wearing and tearing the tube wall attenuation with the long-term friction of warp thread, these all can reduce the air-flow velocity of injection, thereby it is happy wefting insertion to occur, reduces the wefting insertion quality, therefore, after using after a while, measurement to the jet performance of pilot jet is very necessary, in time replace new pilot jet with convenient, thereby the high-quality that guarantees wefting insertion carries out.
And to measure the jet performance of pilot jet effectively, best mode is to carry out in-site measurement, promptly the jet-stream wind size to pilot jet detects in the loom sley groove, because in reed groove (a plurality of special-shaped reed wire phase parallel arranged as shown in Figure 1, formation reed groove) flow velocity of interior jet-stream wind is greater than 100 meter per seconds, flow velocity is very high, and the existing detector that generally is used to measure airflow, its highest measurement speed has only 30 meter per seconds.Simultaneously, because the bore of reed groove only has several millimeters, therefore, need a kind of air stream decetor that can satisfy the requirement of high precision and high flow rate of design, effectively detect with the jet performance to pilot jet, the application just is being based on above-mentioned background and the development and Design of carrying out.
The utility model content
The utility model purpose provides a kind of air stream decetor that can carry out on-the-spot detection to the jet performance of pilot jet.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of air stream decetor that is used for in-site measurement pilot jet jet performance, it comprises detecting head, the other end is connected with reed wire detecting head is fixed on fixed head in the reed groove thereby an end is connected with detecting head, described detector head comprises that external diameter is slightly smaller than the body in reed notch footpath, be plugged in the body front end and parallel the air-flow probe of setting with reed groove bearing of trend, one end is plugged in the interior other end of body and draws this external gas piping, described air-flow probe has the air-flow through hole, described air-flow probe is connected with gas piping, described air-flow probe is gathered the jet-stream wind of pilot jet to be measured, and exports by gas piping.
In the mode according to enforcement that technique scheme is optimized, described fixed head upper end is buckled on the reed cap of reed wire.
The center line of described air-flow probe is 2.0～2.5mm to the distance of reed groove upper limb, and the center line of described air-flow probe to the distance of reed groove inwall is 1.5～2.0mm.
Described air-flow probe is the hollow stainless steel pipe that external diameter is less than or equal to 1.2mm.
Described detecting head also comprise be connected with body be positioned at the outer connector of reed groove, described connector and fixed head removably connect by bolt.
Described body and connector are one-body molded, and it adopts engineering plastics or copper material to make.
Owing to adopt technique scheme, the utlity model has following advantage: when carrying out in-site measurement, at first detector is installed on the reed, detecting head is positioned at the reed groove, and the air-flow probe is positioned at a side of pilot jet to be measured, and the structure of whole air stream decetor is less.The air-flow probe is gathered the air-flow of corresponding auxiliary nozzle ejection, this jet-stream wind is delivered to follow-up treatment circuit by gas piping, as transmitter etc., promptly can analyze the gas velocity of output, whether thereby can detect pilot jet injection flow velocity to this normally judges, when measurement result has differently, will change this pilot jet, thereby guarantee the wefting insertion quality.

Embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the utility model is described:
Air stream decetor as shown in Figures 2 and 3, it is installed on the special-shaped reed wire 20, a plurality of special-shaped reed wire 20 phase parallel arranged, form reed groove 10 between the breach, a plurality of pilot jet (not shown) are installed in the below of reed groove 10 at interval, when needs are measured pilot jet, air stream decetor is installed in the reed groove of pilot jet position one side correspondingly.
Particularly, the air stream decetor of present embodiment is made up of detecting head 1 and fixed head 2, wherein, detecting head 1 concrete structure as shown in Figure 4, it comprises, and external diameter is a bit larger tham the body 11 of reed groove 10 bores, the air-flow probe 12, the end that are plugged in body 11 front ends be plugged in ends in the body 11 stretch out gas piping 13 outside the body 11, with body 11 one connection and be positioned at the connector 14 of reed groove 10 outsides mutually.Air-flow probe 12 is a hollow stainless steel pipe, and its external diameter is less than or equal to 1.2mm, and its center line parallels with the bearing of trend of reed groove 10, and simultaneously, air-flow probe 12 is connected with gas piping 13.The front end of body 11 can be made into taper, and body 11 adopts engineering plastics or copper material to process with connector 14.
Fixed head 2 main bodys are a hang plate, and its lower end and connector 14 removably connect by bolt 21, and the upper end is buckled on the reed cap 201 of reed wire 20, specifically sees shown in Figure 3.
When air stream decetor is installed in the reed groove, in order to guarantee to receive effectively the jet-stream wind of pilot jet, the setting of air-flow probe 12 relative reed grooves 10 can be in the following way: air-flow probe 12 center lines are controlled in 2.0～2.5mm scope (referring to Fig. 5) to the upper limb size a of reed groove, and air-flow probe 12 is controlled at 1.5～2.0mm scope interior (referring to Fig. 6) to the size b of reed groove inwall.
