Description

Technical Field

[0001] This utility model relates to the field of integrated air valves, and in particular to an integrated air valve structure for an air supply system. Background Technology

[0002] In garment printing and embossing processes, the gas supply system has a significant impact on production quality and efficiency. Currently, traditional gas supply systems use multiple single-function valves to control gas flow and pressure separately. These valves are installed in a dispersed manner, which not only occupies a lot of space but also complicates pipeline connections, increasing the risk of gas leaks and the difficulty of installation and maintenance. Each connection node is a potential risk point; once a gas leak occurs, it not only wastes resources but also affects the stability of the gas supply, thereby interfering with the accuracy of printing and embossing. Moreover, the dispersed valve layout makes the overall system appear chaotic. Whether it is spending a lot of time planning pipeline routes and connecting valves during installation or checking the status of each valve individually during subsequent maintenance, it greatly increases labor and time costs. Therefore, an integrated gas valve structure for the gas supply system is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] like Figure 1-5As shown, an integrated gas valve structure for a gas supply system includes a valve body 1. Inside the valve body 1, a flow regulating valve seat 4 and a pressure regulating valve seat 5 are sequentially arranged, as well as an air passage 6 connecting the flow regulating valve seat 4 and the pressure regulating valve seat 5. An air inlet 2 and an air outlet 3 connected to the air passage 6 are respectively arranged on the front and rear sides of the valve body 1. The air inlet 2 is used for gas inflow, and the air outlet 3 is used for gas outflow after regulation. The connection method between the air inlet 2 and the air outlet 3 and the gas supply pipeline can be a standard threaded connection, flange connection, or quick connection interface to facilitate connection with an external gas supply pipeline. The valve body 1 also has a flow regulating chamber 7 and a pressure regulating chamber 8 located above the flow regulating valve seat 4 and the pressure regulating valve seat 5, respectively, thereby forming a space for integrated installation of the flow regulating valve core 12 or the pressure regulating valve core 13, and achieving the effect of simultaneously regulating flow and pressure in the same valve body 1.

[0023] A valve cover 11 is provided on the top of the valve body 1. A flow regulating valve core 12 and a pressure regulating valve core 13 are respectively inserted into the flow regulating chamber 7 and the pressure regulating chamber 8 on the valve cover 11, providing space for the flow regulating valve core and the pressure regulating valve core to be installed and moved. The flow regulating valve core 12 and the pressure regulating valve core 13 are connected by transmission. A drive mechanism 14 is provided on the side of the valve body 1, which is connected by transmission to the flow regulating valve core 12 or the pressure regulating valve core 13.

[0024] With this design, flow and pressure can be regulated in the same valve body 1 through the flow regulating valve core 12 and the pressure regulating valve core 13. At the same time, through the transmission connection between the two, dynamic balance regulation can be achieved through the drive mechanism 14, ensuring that the system always maintains the best performance under different operating conditions.

[0025] It should be noted that the valve body 1 and the valve cover 11 are integrally formed from high-strength aluminum alloy and are fixed together by screws. At the same time, when connecting, a sealing structure, such as a sealing groove and a sealing ring, is set on the contact surface between the valve cover 1 and the valve body 11 to further enhance the sealing performance of the air valve.

[0026] In the preferred embodiment, two opposing first lifting grooves 9 are provided on the inner wall surface of the flow regulating cavity 7. The top of the first lifting groove 9 is open and can be closed by the valve cover 1. This design facilitates the installation of the flow regulating valve core 12.

[0027] The flow regulating valve core 12 includes a first mounting hole 120 on the valve body 1, a first bearing 121 in the first mounting hole 120, a first internal threaded shaft 123 rotatably mounted in the first bearing 121, a first transmission gear 124 fixedly mounted on the top of the first internal threaded shaft 123, and power can be transmitted between the two. A valve stem 125 is inserted into the internal thread of the first internal threaded shaft 123, and a regulating valve head 127 that cooperates with the flow regulating valve seat 4 is mounted on the bottom of the valve stem 125. A first limiting slider 128 that slides with two first lifting slide grooves 9 is mounted on the outside of the valve stem 125. The rotation of the first internal threaded shaft 123 can be converted into the up and down movement of the valve stem 125 through the threaded connection.

[0028] With this design, the first internal threaded shaft 123 can be rotated in the first mounting hole 120 by the first bearing 121 through the first transmission gear 124. At the same time, through the sliding cooperation between the first limit slider 128 and the first lifting slide groove 9, the valve stem 125 can drive the regulating valve head 127 to rise and fall in the flow regulating valve seat 4, thereby realizing the regulation of flow.

[0029] In this embodiment, the regulating valve head 127 is a conical valve head, which has a high fitting accuracy with the flow regulating valve seat 4. The gas flow rate is adjusted by changing the gap between the valve head and the valve seat.

[0030] In the preferred embodiment, the pressure regulating valve core 13 includes a pre-tightening adjustment mechanism disposed on the valve body 1, and a pressure core mechanism disposed in the pressure regulating chamber 8 and cooperating with the pressure regulating valve seat 5. The pre-tightening adjustment mechanism is connected to the first transmission gear 124 of the flow regulating valve core 12. This design allows the pressure to be regulated by adjusting the pre-tightening force of the pressure core mechanism through the pre-tightening adjustment mechanism.

[0031] The inner wall of the pressure regulating chamber 8 is provided with two opposing second lifting slide grooves 10. The top of the second lifting slide groove 10 is open, just like the first lifting slide groove 9. It can be closed by the valve cover 1. This design facilitates the installation of the pressure regulating valve core 13.

[0032] The preload adjustment mechanism includes a second mounting hole 130 on the valve body 1, a second bearing 131 disposed in the second mounting hole 130, a second internal threaded shaft 132 rotatably disposed in the second bearing 131, and a second transmission gear 133 fixedly disposed on the top of the second internal threaded shaft 132, enabling power transmission between the two. The second transmission gear 133 meshes with the first transmission gear 124, thereby realizing the transmission connection between the flow regulating valve core 12 and the pressure regulating valve core 8. A pre-tightening rod 134 is inserted into the internal thread of the 132. The pre-tightening rod 134 has a reserved cavity 135 with an open lower end. A second limiting slider 136 that cooperates with two second lifting slides 10 is provided on the outer side of the bottom of the pre-tightening rod 134. A pressure ring 138 is rotatably connected to the lower end. Through the threaded connection and the sliding cooperation between the second limiting slider 136 and the second lifting slide 10, the rotation of the second internal thread shaft 132 can drive the pre-tightening rod 134 and the pressure ring 138 to move up and down.

[0033] The specific connection method is as follows: the top of the pressure ring 138 is provided with a rotating connecting groove 139, and the bottom of the pretension rod 134 is provided with a rotating connecting ring 137 that cooperates with the rotating connecting groove 139. The cross-sections of the rotating connecting groove 139 and the rotating connecting ring 137 are convex. This design allows the pretension rod 134 and the pressure ring 138 to rotate relative to each other while maintaining the stability of the connection.

[0034] In a preferred embodiment, the pressure core mechanism includes a pressure rod 1310. The top end of the pressure rod 1310 extends through the pressure ring 138 into the reserved cavity 135 of the pre-tightening rod 134. An abutment ring 1311 is provided on the outside of the pressure rod 1310. A stabilizing slider 1312 is provided on the outside of the abutment ring 1311, which slides in cooperation with the two second lifting slide grooves 10. A pre-tightening spring 1314 is fitted on the outside of the pressure rod 1310, located between the abutment ring 1311 and the pressure ring 138. The two ends of the pre-tightening spring 1314 are in contact with the abutment ring 1311 and the pressure ring 138, respectively. The position of the pressure rod is adjusted by the elastic force of the pre-tightening spring 1314. A pressure head 1313 is provided at the bottom of the pressure rod 1310, which cooperates with the pressure regulating valve seat 5. The cooperation between the pressure head 1313 and the pressure regulating valve seat 5 is precisely designed to achieve effective regulation of gas pressure.

[0035] With this design, the pressure rod 1310 can be inserted into the reserved cavity 135 at the top when the pretension rod 134 and the pressure ring 138 are pressed down, thereby adjusting the pretension force of the pretension spring 1314 using the pressure ring 138.

[0036] In a preferred embodiment, the drive mechanism 14 includes a drive device 140 disposed on the side of the valve body 1. A drive gear 141 is disposed on the output shaft of the drive device 140. The drive gear 141 meshes with a first transmission gear 124 or a second transmission gear 133. In this embodiment, the drive gear 141 cooperates with the first transmission gear 124. Through this meshing connection, the drive device can transmit power to the flow regulating valve core 12 or the pressure regulating valve core 13, thereby realizing the driving and regulation of the air valve.

[0037] This design achieves an effective coordination mechanism between flow rate and pressure, allowing for precise and real-time adjustment of gas parameters according to actual process requirements. During the embossing and printing process, it can respond quickly and achieve precise control as needed, improving the stability and reliability of the gas supply system and avoiding problems such as blurred printed patterns and uneven embossing depth.

[0038] It should be noted that the drive mechanism 14 is a drive motor.

[0039] Working principle: The drive mechanism 14 drives the first transmission gear 124 to rotate through the drive gear 141, which in turn drives the first internal thread shaft 123 to rotate, causing the valve stem 125 to move up and down to adjust the flow rate. At the same time, the first transmission gear 124 drives the second transmission gear 133 to rotate, which drives the second internal thread shaft 132 to rotate, pushing the preload rod 134 and the pressure rod 1310 in the pressure core mechanism to move, thereby adjusting the pressure output and realizing the linkage adjustment of flow rate and pressure.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
