[0035] In textile production, air jet looms are often used for weft insertion. During operation, compressed air creates frictional traction on the weft yarn, pulling it through the shed. This process requires high precision and responsiveness, so air jet looms often incorporate solenoid valves to control the opening and closing of compressed air flow to multiple auxiliary nozzles.

[0036] During actual production, the inventors discovered that when air-jet looms are producing narrow-width products, not all auxiliary nozzles need to be in operation. However, the solenoid valves in conventional air-jet looms lack the ability to control the airflow of individual auxiliary nozzles. Multiple auxiliary nozzles can only be opened or closed simultaneously. In this case, the redundant auxiliary nozzles outside the width of the loom remain in the airflow state and cannot be individually closed, resulting in a significant waste of compressed air.

[0037] To address these practical production challenges, the inventors designed an energy-saving air jet switch with a unique structure. This switch not only easily adjusts the flow of compressed air through the shutoff valve, but also maintains the connection orientation between existing devices and leaves ample space for subsequent connections.

[0038] In order to more clearly illustrate the structure of the energy-saving jet switch and the jet control valve, the energy-saving jet switch and the jet control valve will be introduced below with reference to the accompanying drawings.

[0039] See also Figure 1 , Figure 1 FIG1 is a schematic diagram of the structure of an energy-saving jet switch 10 in one embodiment of the present application. An embodiment of the present application provides an energy-saving jet switch 10. The energy-saving jet switch 10 includes a connector 110 and a shut-off valve 120.

[0040] See also Figure 2 , Figure 2 This is a schematic structural diagram of a connector 110 in one embodiment of the present application. The connector 110 is bent to form a first end 110A and a second end 110B. The first end 110A has a first connecting nozzle 111, and the connector can be connected to the solenoid valve of the air jet loom through the first connecting nozzle 111 of the first end 110A. The second end 110B has a second connecting nozzle 112. The first connecting nozzle 111 is internally connected to the second connecting nozzle 112. The auxiliary nozzles of the air jet loom are usually arranged compactly. If a linear connecting component is used, the shape of the components installed after the linear connecting component is more restricted. Therefore, the connector 110 of the present application has a bent first end 110A and a second end 110B, so that when multiple energy-saving air jet switches 10 need to be arranged compactly, each connector 110 can provide sufficient space for the subsequent connection of the shut-off valve 120 in a compact arrangement.

[0041] See also Figure 3 , Figure 3 This is a schematic structural diagram of a stop valve 120 in one embodiment of the present application. The stop valve 120 has a third connecting nozzle 121 and a fourth connecting nozzle 122 that are internally connected. The stop valve 120 is connected to the second connecting nozzle 112 of the connector 110 through the third connecting nozzle 121 and is internally connected. When the connector 110 is connected to the stop valve 120, the opening direction of the fourth connecting nozzle 122 will be consistent with the opening direction of the first connecting nozzle 111. A blocking member is also movably provided on the stop valve. The blocking member can adjust the opening of the communication channel between the first connecting nozzle 111 and the fourth connecting nozzle 122 by changing its position to control the fluid flow through the stop valve 110.

[0042] In some embodiments, the first end portion 110A and the second end portion 110B are both linear tubular structures to reduce resistance to the fluid.

[0043] In some embodiments, the second connection nozzle 112 and the third connection nozzle 121 both have a threaded structure, wherein the second connection nozzle 112 can be threadedly connected to the third connection nozzle 121 .

[0044] In some embodiments, the threads of the third connection nozzle 121 are external, while the threads of the second connection nozzle 112 are internal. Because the internal structure of the shut-off valve 120 includes a blocking member, the structure is more complex. Therefore, the threads of the third connection nozzle 121 of the shut-off valve 120 are external to avoid further increasing the complexity of the internal structure of the shut-off valve 120. In this case, to threadably connect with the third connection nozzle 112, the threads of the second connection nozzle 112 should be internal.

[0045] In some embodiments, the specification of the thread of the second connecting nozzle 112 is 3 / 8 thread, and the specification of the thread of the third connecting nozzle 121 is 3 / 8 thread.

[0046] In some embodiments, the first connecting nozzle 111 has an external thread. The surface of the electromagnetic valve of the air jet loom is usually internally threaded. Setting the thread of the first connecting nozzle 111 to an external thread can make the energy-saving air jet switch 10 adaptable to more electromagnetic valves.

[0047] In some embodiments, the specification of the thread of the first connection nozzle 111 is 3 / 8 thread.

[0048] In some embodiments, the fourth connection nozzle 122 has internal threads. The fourth connection nozzle 122 is the end of the energy-saving air jet switch 10 that is used to connect to other textile equipment. This internal thread not only facilitates connection between devices but also effectively prevents deterioration of the thread structure of the fourth connection nozzle 122 when the energy-saving air jet switch is not used for an extended period of time.

[0049] In some embodiments, the specification of the thread of the fourth connection nozzle 122 is M10 thread.

[0050] In some embodiments, the stop valve 120 includes a rotary handle 123. By rotating the rotary handle 123, the opening and closing of the blocking member can be controlled, thereby controlling the on / off state of the stop valve 120.

[0051] In some embodiments, the connecting member 110 is bent at a right angle, that is, the axis of the first end 110A and the axis of the second end 110B are perpendicular to each other.

[0052] In some embodiments, the opening direction of the fourth connection nozzle 122 is aligned with the opening direction of the first connection nozzle 111. For example, when the connector 110 is bent at a right angle, in order to ensure that the opening direction of the fourth connection nozzle 122 of the energy-saving air switch 10 is aligned with the opening direction of the first connection nozzle 111, the opening directions of the third connection nozzle 121 and the fourth connection nozzle 122 are perpendicular to each other. This arrangement allows the energy-saving air switch to maintain the original flow direction of the compressed air.

[0053] In some embodiments, the shutoff valve 120 is an angle valve. This valve has a right-angled internal communication channel, with the opening directions of the third connection nozzle 121 and the fourth connection nozzle 122 being perpendicular to each other. In this case, the rotary handle 123 is a rotary switch with a 90-degree limit. Rotating the rotary handle 123 90 degrees switches the angle valve open or closed.

[0054] In some embodiments, the rotary handle 123 is a flat handle. When the flat handle's "-" orientation is perpendicular to the opening direction of the fourth connection nozzle 122, the angle valve is in a closed state; when the flat handle's "-" orientation is parallel to the opening direction of the fourth connection nozzle 122, the angle valve is in a flow-through state. With this arrangement, the angle valve's open / closed state can be determined by observing the orientation of the flat handle.

[0055] In some embodiments, the present application further provides an injection control valve.

[0056] See also Figure 4 , Figure 4This is a schematic diagram of the structure of an air jet control valve in one embodiment of the present application. The air jet control valve includes the aforementioned energy-saving air jet switch 10 and a solenoid valve 20. The energy-saving air jet switch 10 is connected to the solenoid valve 20 via a first connecting nozzle 111. The solenoid valve 20 is capable of connecting to an auxiliary nozzle of an air jet loom and conducting airflow from the auxiliary nozzle. The air jet control valve can be used to control the airflow from the auxiliary nozzle on and off.

[0057] In some embodiments, the solenoid valve 20 has a plurality of air nozzles 210 arranged in a matrix. The arrangement of the plurality of air nozzles 210 is adapted to the auxiliary nozzles of the air jet loom.

[0058] In some embodiments, the solenoid valve 20 has four air nozzles 210 arranged in a matrix. The arrangement of the four air nozzles 210 is compatible with the auxiliary nozzles of the Toyota 710 air jet loom or the Toyota 810 air jet loom.

[0059] In some embodiments, the gas nozzle 210 has an internal thread. The energy-saving air jet switch 10 can be threadedly connected to the gas nozzle 210 through the first connecting nozzle 111 having an external thread.

[0060] In some embodiments, the thread specification of the air nozzle 210 of the solenoid valve 20 is 3 / 8 thread.

[0061] In some embodiments, the solenoid valve 20 can simultaneously open or close multiple air nozzles 210. The air jet control valve includes multiple energy-saving air jet switches 10, each of which is connected to a different air nozzle 210. When the solenoid valve 20 opens the multiple air nozzles 210, the energy-saving air jet switches 10 connected to each air nozzle 210 can independently control whether each air nozzle 210 is connected to the outside world, thereby achieving the effect of independently controlling the airflow of the auxiliary nozzle.

[0062] The above-described embodiments merely represent several embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
