Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: a kind of jet loom for drawing weft yarn Weft selector, its structure is as it is shown in figure 1, include: source of the gas 1, and source of the gas 1 is with main
Outlet pipe 2 is connected；
Described main outlet pipe 2 respectively with first pressure-relief valve the 3, second pressure-relief valve 4, reversal valve the 5, the 4th pressure-relief valve 13 and often
Air jet pipe 10 is connected；
Described reversal valve 5 is connected with the first main jet trachea 6 and the second main jet trachea 7 respectively；
First main jet trachea 6 is connected with the first escape pipe 8 by the 5th pressure-relief valve 7；
Second main jet trachea 14 is connected with the second escape pipe 11 by the 3rd pressure-relief valve 12；
Described 4th pressure-relief valve 13 is connected with the second escape pipe 11；
Described normal air jet pipe 10 is connected with the first escape pipe 8 by pressure-relief valve 9.
Described source of the gas 1 is air pump.
Described reversal valve 5 is bidirectional rotary rotary valve.
The spool of described reversal valve 5 is ceramic material.
Wherein, described first pressure-relief valve 3 is total relief valve.
The principle of the present invention is:
Airflow direction is as shown by arrows in FIG..The gases at high pressure that air pump produces are through main outlet pipe 2, at the first pressure-relief valve
3 and second pressure-airs after pressure-relief valve 4 release, a road enters reversal valve 5, and under main frame electrical control, pressure-air is by the
One main jet trachea 6 or the second main jet trachea 14 spray, and then pass through the 5th pressure-relief valve 7 or the 3rd pressure-relief valve 12 carries out secondary fall
Pressure, the air-flow after release enters the first escape pipe 8 or the second escape pipe 11, carries out wefting insertion.
Because there being the existence of multiple pressure-relief valve, so the gases at high pressure that air pump produces are after the 4th pressure-relief valve 13 release
Low-pressure air enters the second escape pipe 11, to keep low pressure always.
The gases at high pressure that air pump produces low-pressure air after pressure-relief valve 9 release enters the first escape pipe 8, also keeps one
Straight low pressure.
When needing the first escape pipe 8 wefting insertion under main frame electrical control, the Spool rotating of reversal valve 5 is the first main jet trachea
6 connect, and simultaneously close off and the connection of the second main jet trachea 14.When needing the first main jet trachea 6 wefting insertion under main frame electrical control,
The Spool rotating of reversal valve 5 connects the first escape pipe 8.When needing the second escape pipe 11 wefting insertion under main frame electrical control, change
To the Spool rotating of valve 5, second main jet trachea 14 is connected, simultaneously close off and the connection of the first main jet trachea 6.Complete to select color
Function.
In brief, whether which root main jet trachea of the decision of reversal valve 5 ventilates.
In the case of reversal valve 5 is failure to actuate, the first escape pipe 8 and the second escape pipe 11 have depositing of low-pressure air current all the time
, so carrying out wefting insertion very easily.
In the present invention, if desired three sprays and three sprays can increase the respective numbers of reversal valve 5 time above and complete to select latitude function,
By changing the model of reversal valve 5, and relevant pipeline can also be revised complete.The spool of reversal valve 5 is preferably pottery, tool
The advantage having oil-resistant high-temperature abrasion-resistant life-span length.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
