Description
Technical field
The present invention relates to textile machine technical equipment field, specifically, relate to a kind of jet loom for drawing weft yarn Weft selector.
Background technology
At present carrying out during wefting insertion selects latitude, needing to rely on electromagnetic valve is that air-flow commutates.And gas flow temperature out is higher from air pump, pressure is bigger.Airflow function is after the spool of electromagnetic valve, and spring within electromagnetic valve and coil are damaged at short notice because of the High Temperature High Pressure of air-flow, and for different parallels, it needs multiple electromagnetic valves to control air-flow size respectively and whether air-flow turns on.And the damage of electromagnetic valve causes production cost to reduce further.
For these reasons, how to design a kind of new wefting insertion weft selecting mechanism, be those skilled in the art's problems of needing solution badly.
Summary of the invention
It is an object of the invention to as overcoming above-mentioned the deficiencies in the prior art, it is provided that a kind of jet loom for drawing weft yarn Weft selector.This device is by designing brand-new structure, it is simple to different weft yarns select latitude and wefting insertion.
In order to reach above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of jet loom for drawing weft yarn Weft selector, including:
Source of the gas, source of the gas is connected with main outlet pipe；
Described main outlet pipe is connected with pressure-relief valve, pressure-relief valve, reversal valve, pressure-relief valve and normal air jet pipe respectively；
Described reversal valve is connected with the first main jet trachea and the second main jet trachea respectively；
First main jet trachea is connected by having pressure-relief valve and the first escape pipe；
Second main jet trachea is connected by pressure-relief valve and the second escape pipe；
Described pressure-relief valve and the second escape pipe are connected；
Described normal air jet pipe is connected by pressure-relief valve and the first escape pipe；
Gases at high pressure one tunnel that source of the gas produces becomes low-pressure gas after pressure-relief valve release and flows out from the second escape pipe, and another road gas becomes low-pressure gas after pressure-relief valve and flows out from the first escape pipe；
Reversal valve controls the pressure change of the first outlet pipe and the second escape pipe；
Over-pressure gas in main outlet pipe flows out from pressure-relief valve and pressure-relief valve.
Preferably, described source of the gas is air pump.
Preferably, described reversal valve is bidirectional rotary rotary valve.
Preferably, the spool of described reversal valve is ceramic material.
Preferably, described reversal valve is rotary valve.
The invention has the beneficial effects as follows:
By arranging multiple pressure-relief valve so that different pipelines is provided with different pressure.Different tube fit reversal valve so that the first escape pipe or giving vent to anger of the second escape pipe are controlled, just can select the weft yarn of different colours by controlling different escape pipes.Reversal valve is common rotary valve, so its spool has good high temperature resistant, high pressure and oil resistivity, cheap, service life is long.Rely on overall new construction and the existence of pressure-relief valve so that this device can obtain the air-flow of expecting pressure, greatly reduces production cost simultaneously.

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 connected with main outlet pipe 2；
Described main outlet pipe 2 is connected with pressure-relief valve 3, pressure-relief valve 4, reversal valve 5, pressure-relief valve 13 and normal air jet pipe 10 respectively；
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 there being pressure-relief valve 7；
Second main jet trachea 14 is connected with the second escape pipe 11 by pressure-relief valve 12；
Described 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 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, pressure-air after pressure-relief valve 3 and pressure-relief valve 4 release, one tunnel enters reversal valve 5, under main frame electrical control, pressure-air is sprayed by the first main jet trachea 6 or the second main jet trachea 14, then passing through pressure-relief valve 7 or pressure-relief valve 12 carries out secondary blood pressure lowering, 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 low-pressure air that the gases at high pressure of air pump generation are after pressure-relief valve 13 release 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 low pressure always.
When needing the first escape pipe 8 wefting insertion under main frame electrical control, the Spool rotating of reversal valve 5 connects the first main jet trachea 6, simultaneously closes 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, the Spool rotating of reversal valve 5 connects the second main jet trachea 14, simultaneously closes off and the connection of the first main jet trachea 6.Complete to select the function of color.
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 the existence 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, it is also possible to by changing the model of reversal valve 5, and revise relevant pipeline and complete.The spool of reversal valve 5 is preferably pottery, the advantage with 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, and generic principles defined herein can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
