Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] Please see Figures 1-6As shown, the air path adjusting device comprises a base body 100, the base body 100 comprises a first channel 101, a second channel 102 and a third channel 103, the first channel 101 extends along a first direction and is arranged through the base body 100 to form a first opening 106 and a second opening 107, the second channel 102 extends along a second direction and is arranged through the base body 100 to form a third opening 108 and a fourth opening 109, the third channel 103 extends along a third direction and is arranged through the base body 100 to form a fifth opening 110 and a sixth opening 111; an adjusting rod, the adjusting rod comprises a rod body 300 and an adjusting part 400, the adjusting part 400 is located at the communication between the first channel 101 and the second channel 102, the rod body 300 is located in the first channel 101 and close to the side of the first opening 106, and at least part of the rod body 300 is exposed to the base body 100 at the first opening 106, the adjusting part 400 is provided with a fourth channel 104 and a fifth channel 105, the third channel 103 extends along the first direction and is arranged through the adjusting part 400 away from the side of the rod body 300, the fifth channel 105 extends along the second direction or the third direction and is arranged through one side of the adjusting part 400, and the third channel 103 communicates with the fourth channel 104; wherein any one of the first direction, the second direction and the third direction is perpendicular to the other two directions.

[0030] The base body 100 here is the basic structural member of the entire device, which bears the functions of constructing air path channels and accommodating other components. The design of the first channel 101, the second channel 102 and the third channel 103 perpendicular to each other enables the air path to be laid out and adjusted in three different spatial dimensions. The first opening 106, the second opening 107, the third opening 108, the fourth opening 109, the fifth opening 110 and the sixth opening 111 are respectively used as the entrances and exits of the respective channels connecting with the external air path. The rod body 300 of the adjusting rod is mainly used for the user to exert external force for adjustment operation, and it is exposed to the first opening 106 of the base body 100 for convenient operation. The adjusting part 400 is the key part for realizing the adjustment of the flow and pressure of the air path, and the existence of the fourth channel 104 and the fifth channel 105 and their communication relationship with the third channel 103 can change the flow passage area and the air flow direction of the air path through the rotation or displacement of the adjusting part 400, so as to realize the adjustment of the flow and pressure. For example, when the adjusting part 400 rotates, the overlapping area of the fourth channel 104 with the first channel 101 and the second channel 102 changes, thereby changing the resistance of the gas passing through, and realizing the adjustment of the flow and pressure.

[0031] The unique design of the multi-channel vertical layout and the adjusting rod enables the device to independently and accurately adjust multiple gas paths. Different direction channels can be connected to different gas sources or gas-using equipment. Through the operation of the adjusting rod, the flow and pressure of each channel can be accurately controlled according to actual needs, avoiding mutual interference between channels, improving the adjustment accuracy and stability of the gas path system, and being suitable for complex multi-gas path application scenarios, such as multi-gas mixing and conveying systems in large-scale chemical production or gas path supply systems for high-precision experimental instruments.

[0032] The gas path adjusting device further comprises connecting pieces 120, which are respectively threadedly connected to the second opening 107, the third opening 108, the fourth opening 109, the fifth opening 110, and the sixth opening 111. At least three connecting pieces 120 are provided with connecting pipelines 121 away from the base body 100 on one side, for connecting the gas paths.

[0033] The connecting pieces 120 serve as a bridge connecting the base body 100 and the external gas path. The threaded connection ensures the firmness and sealing of the connection. By providing connecting pipelines 121 on some connecting pieces 120, the device can be easily connected to the existing gas path system. For example, in the gas path of an industrial automated production line, the connecting pieces 120 can connect the device with gas sources, execution cylinders, and other equipment. According to the actual gas path layout requirements, the number and position of connecting pieces 120 with connecting pipelines 121 can be flexibly selected to make the gas path connection more convenient and efficient.

[0034] The design of the connecting pieces 120 greatly improves the versatility and installation convenience of the device. Threaded connection ensures the tightness of the connection, reducing the risk of gas leakage. The provision of connecting pipelines 121 enables the device to quickly and accurately interface with external gas paths, whether it is a newly built gas path system or a modification and upgrade of an existing system. This makes it easy to implement, reduces installation costs and time, and improves the construction efficiency of the gas path system.

[0035] The adjusting part 400 is in a spherical structure.

[0036] The spherical structure of the adjusting part 400 is because the sphere has good geometric properties. During the gas path adjustment process, the spherical adjusting part 400 can achieve relatively uniform stress in all directions. When rotating or displacing, the contact area and angle between the spherical adjusting part 400 and the channel wall change relatively smoothly. For example, when changing the communication cross-sectional area of the fourth channel 104 with other channels, the spherical adjusting part 400 can achieve precise adjustment with relatively small resistance. No matter from which angle the adjusting operation is performed, its influence on the gas path is relatively stable and predictable. Compared with other shapes of adjusting parts 400, it can provide more accurate and flexible gas path adjustment effect.

[0037] The application of the spherical adjustment part 400 significantly improves the accuracy and flexibility of the adjustment. Its uniform stress characteristics make the adjustment process more stable, reducing the gas path fluctuations caused by the adjustment part 400 piece jam or sudden changes. In scenarios that require frequent adjustment of gas path parameters, such as gas supply control in semiconductor manufacturing processes, the spherical adjustment part 400 can quickly respond and accurately adjust, improving the stability of the production process and product quality.

[0038] The gas path adjustment device also includes a fastener 130, which is located near the inner end of the connecting piece 120 in the base body 100, and the fastener 130 also abuts the side wall of the adjustment part 400, so as to improve the stability of the adjustment part 400.

[0039] The fastener 130 is mainly used to enhance the stability of the adjustment part 400 during work. In the gas path, the flow of gas will generate a certain pressure and impact force, which may cause the adjustment part 400 to displace or sway. The fastener 130 can limit unnecessary movement of the adjustment part 400 by abutting on the side wall of the adjustment part 400. For example, when the gas path pressure changes suddenly, the fastener 130 can prevent the adjustment part 400 from deviating from the predetermined adjustment position due to uneven stress, ensuring that the adjustment part 400 is always in a stable working state, ensuring the accuracy and reliability of the gas path adjustment.

[0040] The presence of the fastener 130 effectively improves the stability of the adjustment part 400. In long-term operation or complex gas path environment, it can reduce the accumulation of adjustment errors caused by the instability of the adjustment part 400. This is particularly important for applications that require high-precision gas path control, such as gas simulation systems in aerospace experiments, which can ensure stable output of gas path parameters, improve the accuracy and reliability of experimental data, and also prolong the service life of the device.

[0041] The side of the fastener 130 that is in contact with the adjustment part 400 is arc-shaped.

[0042] The side of the fastener 130 that is in contact with the adjustment part 400 is designed to be arc-shaped, in order to better adapt to the spherical adjustment part 400. The arc-shaped structure can increase the contact area between the fastener 130 and the adjustment part 400, making the force distribution between them more uniform. When the adjustment part 400 is subjected to gas pressure or external force, the arc-shaped fastener 130 can better withstand and distribute these forces, avoiding damage to the adjustment part 400 or affecting its stability due to local stress concentration. For example, in high-pressure gas path systems, the arc-shaped fastener 130 can effectively fix the adjustment part 400 in the predetermined position without damaging the surface of the adjustment part 400, ensuring the normal operation and service life of the adjustment part 400.

[0043] The arc-shaped fastener 130 further enhances the stability of the adjustment section 400 and the reliability of the device. The uniform force distribution reduces the risk of component wear and damage, enabling stable operation even in high-pressure, high-flow-rate gas environments. In industrial gas delivery and distribution systems, this design reduces maintenance costs and downtime, improving the overall efficiency of the gas system.

[0044] An assembly cylinder 140 extending in the first direction is provided on the side of the first channel 101 near the first opening 106. The side wall of the rod 300 abuts against the inner wall of the assembly cylinder 140, and a sealing ring 141 is provided between the side wall of the rod 300 and the inner wall of the assembly cylinder 140.

[0045] The assembly sleeve 140 provides positioning and support for the rod 300 within the first channel 101. The rod 300 abuts against the inner wall of the assembly sleeve 140, ensuring the straightness and stability of the rod 300 during rotation or movement. The sealing ring 141 is designed to prevent gas leakage from the gap between the rod 300 and the assembly sleeve 140. For example, under high gas pressure conditions, the sealing ring 141 effectively prevents gas leakage, ensuring the airtightness of the gas system. The sealing ring 141 can be made of materials with good sealing properties, such as rubber or polytetrafluoroethylene, and can be selected according to different gas pressures and media requirements.

[0046] The combined design of the assembly cylinder 140 and the sealing ring 141 significantly improves the sealing performance of the device. Good sealing performance not only ensures stable pressure in the gas circuit system, preventing pressure drops and flow changes caused by gas leaks, but also enhances the safety of the device. In gas circuit systems involving toxic, flammable, or explosive gases, improved sealing performance is particularly important, effectively preventing safety accidents caused by gas leaks and ensuring the safety of personnel and equipment.

[0047] The base 100 has a snap-fit ​​ring 160 and a rotating ring 150 arranged along the first direction near the first opening 106. The snap-fit ​​ring 160 snaps onto the side wall at the first opening 106, and the rotating ring 150 snaps onto the rod 300. The rotating ring 150 rotates with the rotation of the rod 300. The rotating ring 150 has at least one first positioning protrusion 151 on the side near the snap-fit ​​ring 160, and the snap-fit ​​ring 160 has at least one second positioning protrusion 161 corresponding to the positioning protrusion. When the rod 300 rotates, any one of the first positioning protrusions 151 can snap onto the second positioning protrusion 161.

[0048] The design of the clamping ring 160 and the rotating ring 150 is mainly used to accurately control the rotation angle of the rod body 300. The clamping ring 160 is fixed on the side wall of the first opening 106 of the base body 100, which plays a stable positioning role. The rotating ring 150 is sleeved on the rod body 300 and can rotate with the rotation of the rod body 300. The first positioning protrusions 151 on the upper surface of the rotating ring 150 and the second positioning protrusions 161 on the clamping ring 160 cooperate with each other. When the rod body 300 is rotated to a certain angle, the first positioning protrusions 151 will be clamped into the second positioning protrusions 161, realizing accurate locking of the rotation angle of the rod body 300. For example, when it is necessary to adjust the gas flow or pressure to a specific value, the rod body 300 can be rotated. When the clamping sound of the first positioning protrusions 151 and the second positioning protrusions 161 is heard, it is known that the predetermined adjustment position has been reached. This design makes the adjustment process more accurate and repeatable.

[0049] The structure of the clamping ring 160 and the rotating ring 150 effectively improves the accuracy and repeatability of the adjustment. In industrial production, the accurate control of the gas path parameters is required. This design can ensure that each adjustment can achieve the same effect, reducing the product quality fluctuations caused by human operation errors. In the automatic production line, accurate gas path adjustment helps to improve production efficiency and product consistency, and reduce the scrap rate.

[0050] The side wall of the base body 100 near the first opening 106 is provided with a positioning groove 170 arranged in the first direction, and the clamping ring 160 is provided with a positioning block 171 clamped in the positioning groove 170, which is used to limit the rotation of the clamping ring 160 around the rod body 300.

[0051] The cooperation of the positioning groove 170 and the positioning block 171 further enhances the stability of the clamping ring 160. The clamping ring 160 needs to maintain a fixed position during the gas path adjustment process. The positioning block 171 clamped in the positioning groove 170 can effectively prevent the clamping ring 160 from rotating due to the impact force of the gas or other external forces. For example, in the high-pressure and high-speed gas flow gas path, the impact force of the gas on the adjustment part 400 is large. The design of the positioning groove 170 and the positioning block 171 can ensure the stability of the clamping ring 160, thereby ensuring the normal operation of the entire adjustment mechanism and avoiding the decrease of adjustment accuracy caused by the displacement of the clamping ring 160.

[0052] This design improves the stability of the clamping ring 160, and further improves the reliability of the entire adjustment device. In a complex and harsh gas path environment, it can ensure the stable operation of the adjustment mechanism and reduce the probability of failure caused by loose or displacement of parts. In a long-term continuous operation gas path system, such as a gas supply system of a large power plant, it can reduce maintenance cost and downtime, and improve the overall operation efficiency of the system.

[0053] The elastic member 180 is arranged in the base body 100 and abuts between the clamping ring 160 and the inner wall of the base body 100. The base body 100 is provided with an annular groove near the first opening 106, and the rotating ring 150 is clamped in the annular groove to improve the tightness of the assembly of the clamping ring 160 in the first direction.

[0054] The elastic member 180 provides a pre-tightening force between the clamping ring 160 and the base body 100. During the operation of the gas circuit, vibrations or pressure fluctuations may occur. The elastic member 180 can absorb these energies to prevent the clamping ring 160 from loosening due to vibrations. The annular groove provides a stable mounting position for the rotating ring 150, which can better cooperate with the clamping ring 160 in the first direction. For example, when the gas circuit system starts or stops, a large pressure impact will occur. The elastic member 180 can buffer this impact to ensure that the clamping ring 160 is always tightly attached to the base body 100, and the rotating ring 150 can stably work in the annular groove to ensure the normal operation of the adjusting device.

[0055] The design of the elastic member 180 and the annular groove enhances the anti-vibration performance of the device and the tightness of the assembly between components. In actual application, the gas circuit system is often subject to various external disturbances. This design can make the device maintain stable performance under these disturbances. In the gas circuit system of a transportation tool, such as the brake gas circuit of a car or the air conditioning gas circuit of an airplane, the reliability and safety of the system can be improved, and the damage and failure of components caused by vibrations can be reduced.

[0056] The rod body 300 is further sleeved with a limiting plate 200, which is sleeved on the rod body 300 and located on the side of the rotating ring 150 away from the clamping ring 160. When the limiting plate 200 rotates, it abuts against the side wall at the first opening 106 to limit the rotation range of the adjusting member.

[0057] In summary, first, the rod body 300 of the adjusting rod is inserted into the first channel 101 of the base 100, and the adjusting part 400 is located at the communication between the first channel 101 and the second channel 102. The base 100 serves as the core framework of the entire device, and the first channel 101 thereof is carefully designed to extend along a first direction and pass through to form a first opening 106 and a second opening 107, the second channel 102 extends along a second direction and passes through to form a third opening 108 and a fourth opening 109, the third channel 103 extends along a third direction and passes through to form a fifth opening 110 and a sixth opening 111, and the three directions are perpendicular to each other. This unique layout is like building a precise gas transportation hub, providing a high-efficiency and orderly transmission path for gases of different sources and destinations without interference. For example, in some complex industrial automation production processes, it may be necessary to control the flow and pressure of multiple gases of different properties, such as oxygen, nitrogen, and hydrogen, at the same time. The structure of the base 100 can ensure stable transmission of each gas in its own independent channel, avoiding adjustment confusion caused by channel intersection or gas flow interaction, and greatly improving the adaptability and precise control ability of the gas path system to complex working conditions.

[0058] The assembly cylinder 140 is installed in the first channel 101 near the first opening 106, and a sealing ring 141 is installed between the side wall of the rod body 300 and the inner wall of the assembly cylinder 140 to ensure sealing performance. The assembly cylinder 140 not only provides precise positioning and guidance for the rod body 300, allowing it to move smoothly along the predetermined trajectory in the first channel 101, but also plays a crucial role between the inner wall of the assembly cylinder 140 and the side wall of the rod body 300. The sealing ring 141 is made of special rubber material with good elasticity and corrosion resistance, which can tightly fit the small gap between the rod body 300 and the assembly cylinder 140, forming a reliable gas barrier. In high-pressure gas delivery scenarios, such as high-pressure gas reaction devices in the petrochemical industry, even extremely small gas leaks can cause serious safety accidents, and the combined design of the assembly cylinder 140 and the sealing ring 141 in the device can effectively prevent such situations from occurring, ensuring that the pressure in the gas path system is stable and maintained at the preset level, and ensuring the safety and continuity of the entire production process.

[0059] Then, the clamping ring 160 is clamped in the positioning groove 170 of the sidewall of the base body 100 near the first opening 106 through the positioning block 171, and then the rotating ring 150 is clamped and sleeved on the rod body 300, and the rotating ring 150 is located in the annular groove, and at the same time, the elastic member 180 is installed between the clamping ring 160 and the inner wall of the base body 100. The clamping ring 160 is precisely matched with the positioning groove 170 through the positioning block 171, like a key node firmly anchored on the base body 100, which provides a stable reference position for the whole adjusting mechanism. The rotating ring 150 is tightly sleeved on the rod body 300, and the matching precision between the two is extremely high. When the rod body 300 rotates, the rotating ring 150 can follow the rotation like a shadow. The first positioning protruding strip 151 on the rotating ring 150 cooperates with the second positioning protruding strip 161 on the clamping ring 160, like a precise lock and key. Whenever the rod body 300 rotates to a certain angle, the first positioning protruding strip 151 accurately clamps into the second positioning protruding strip 161, realizing micron-level accurate control of the rotating angle of the rod body 300. The elastic member 180 can be a high-strength spring installed between the clamping ring 160 and the inner wall of the base body 100, continuously applying appropriate pre-tightening force to the clamping ring 160. During the operation of the gas path system, it is inevitably disturbed by various vibrations and pressure fluctuations, such as in the pneumatic control system of large mechanical equipment, the start-stop and mechanical vibration during operation of the equipment will be transmitted to the gas path, and the elastic member 180 can effectively absorb and buffer these energies, prevent the clamping ring 160 from being displaced or loosened due to external impact, and at the same time ensure that the rotating ring 150 always works stably in the annular groove, ensuring the reliability and stability of the whole adjusting device, so that the adjustment of the gas path parameters can always be accurate and consistent.

[0060] Then, the fastener 130 is installed at the end of the connecting piece 120 close to the base 100, the connecting piece 120 is respectively screwed to the second opening 107, the third opening 108, the fourth opening 109, the fifth opening 110 and the sixth opening 111 of the base 100, and the connecting pipe 121 for connecting the gas path is connected to the at least three connecting pieces 120 away from the base 100. The connecting piece 120 is made of high-strength metal material, and the screwing mode has very high connection strength and sealing performance, like a solid bridge, which tightly connects the base 100 and the external gas path together. The fastener 130 is the faithful assistant of the adjusting part 400, which is installed at the end of the connecting piece 120 close to the base 100 and abuts against the side wall of the adjusting part 400. The side of the fastener 130 close to the adjusting part 400 is carefully designed as an arc structure, which perfectly fits the outer surface of the spherical adjusting part 400, can maximize the contact area between them, and can evenly distribute the force applied by the fastener 130 to the surface of the adjusting part 400, avoiding damage to the adjusting part 400 caused by local stress concentration. In some fields with very high requirements for gas path stability, such as ultra-pure gas supply system in semiconductor manufacturing process, even extremely small shaking or displacement of the adjusting part 400 can cause fluctuations in gas flow and pressure, and then affect the manufacturing quality of semiconductor chips. The ingenious design of the fastener 130 and the adjusting part 400 and the reliable connection of the connecting piece 120 in the device can ensure that the adjusting part 400 always remains stable in the complex and changeable gas flow environment, providing highly stable and reliable gas path guarantee for semiconductor manufacturing, greatly improving the yield of chips.

[0061] Adjusting operation: the user rotates the rod 300 exposed at the first opening 106 of the base 100, which drives the rotating ring 150 to rotate, and when the first positioning convex strip 151 on the rotating ring 150 is clamped with the second positioning convex strip 161 on the clamping ring 160, the rotation angle of the rod 300 is accurately controlled, thereby driving the adjusting part 400 to rotate. The spherical structure of the adjusting part 400 changes the communication cross-sectional size of the fourth channel 104, the fifth channel 105 and the channels of the base 100, thereby realizing the adjustment of the gas flow and pressure. During the adjustment process, the fastener 130 always abuts against the side wall of the adjusting part 400, thereby ensuring the stability of the adjusting part 400, the connecting piece 120 stably connects the base 100 and the external gas path, and the whole device works cooperatively to realize the accurate and stable adjustment of the gas flow and pressure. The spherical adjusting part 400 has excellent performance in adjusting the gas path due to its smooth appearance and unique structural characteristics. When it is necessary to increase the gas flow, the user rotates the rod 300, which drives the spherical adjusting part 400 to rotate, so that the overlapping area of the fourth channel 104 and the fifth channel 105 and the channels of the base 100 increases, the resistance of the gas passing through decreases, and the flow increases; conversely, when it is necessary to reduce the flow, the adjusting part 400 is rotated to reduce the overlapping area of the channels, thereby reducing the flow. In the gas supply system of a medical laboratory, the flow and pressure of oxygen, carbon dioxide and other gases may need to be accurately controlled for different experimental steps. The spherical adjusting part 400 can realize accurate flow and pressure changes with a small adjustment step, meet the stringent requirements of experiments on the gas environment, and provide accurate and reliable data support for medical research. At the same time, the cooperative action of the components of the whole device ensures that the gas path system can still operate stably under long-time and high-frequency adjustment operations. For example, in the paint spraying workshop of the automobile manufacturing industry, the pneumatic spray gun needs to be frequently adjusted in terms of gas pressure and flow to ensure the uniformity and quality stability of the paint spraying effect. The close cooperation of the components of the device can effectively reduce the accumulation of adjustment errors caused by component wear or performance degradation, prolong the service life of the device, reduce the maintenance cost and downtime of the equipment, and improve the production efficiency.

[0062] The gas path adjusting device provided in the embodiments of the present application can make the gas paths connected at the two openings communicate by rotating adjustment, select and adjust different two gas paths to be connected by rotating the adjusting part, and improve the versatility and convenience of the gas path adjusting device.

[0063] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, and therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
