Description

Technical Field

[0001] This utility model relates to the field of air valve technology, and in particular to an air valve regulating component that is easy to operate. Background Technology

[0002] Pneumatic control valves are key devices for regulating parameters such as gas flow and pressure in industrial automation process control. The regulating component of the pneumatic control valve is the core device for achieving precise flow control, which is mainly achieved by changing the flow cross-sectional area.

[0003] The throttle valve disclosed in Chinese patent CN203784314U includes a valve core, a valve body, a sealing nut, a screw plug, a spring, a ball, an adjusting nut, a locking nut, a second sealing ring, a fixing rod, a third sealing ring, and a first sealing ring. The upper part of the valve core is provided with an adjusting nut for adjusting the valve core, and the first threaded section of the valve core is provided with a locking nut for locking the valve core. The locking nut is threadedly connected to the first threaded section and is located between the sealing nut and the adjusting nut.

[0004] Before adjusting the throttle valve, the locking nut needs to be loosened before the regulating valve core can be turned. After the regulating valve core is adjusted to the correct position, the locking nut needs to be tightened again, which requires turning the locking nut multiple times, making the operation inconvenient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a convenient air valve regulating component with a reasonable structural design and easy operation.

[0006] The technical solution adopted by this utility model to solve its technical problem is a convenient-to-operate air valve adjustment assembly. The adjustment assembly is installed on the air valve body and includes a valve core, an adjustment rod, a torsion cap, and a connecting sleeve. A locking sleeve is fixedly provided at the top of the valve core. The adjustment rod is threadedly connected to the inner cavity of the locking sleeve. The lower end of the adjustment rod extends into the inner cavity of the valve core. The upper end of the adjustment rod is fixedly connected to the torsion cap. The upper end of the connecting sleeve is limited and fitted on the torsion cap. The lower end of the connecting sleeve can be limited and fitted on the locking sleeve. A support structure is also provided between the connecting sleeve and the locking sleeve. After the lower end of the connecting sleeve is released from the locking sleeve, the support structure allows the connecting sleeve to be rotatably supported on the locking sleeve.

[0007] The advantages of the above technical solution are as follows: When the adjusting rod needs to be turned, pulling the connecting sleeve upward releases the lower end of the connecting sleeve from the limiting position of the locking sleeve, allowing the connecting sleeve to rotate. Simultaneously, the upper end of the connecting sleeve forms a limiting engagement with the torsion cap, causing the torsion cap to rotate. The torsion cap then drives the adjusting rod to rotate, allowing for flow regulation. Furthermore, due to the support structure, the connecting sleeve is rotatably supported on the locking sleeve. At this time, the upper end of the connecting sleeve also maintains a limiting engagement with the torsion cap. Therefore, the operator does not need to pull the connecting sleeve during rotation. After adjustment, the operator applies force to the connecting sleeve again, releasing the support structure and causing the lower end of the connecting sleeve to re-establish a limiting engagement with the locking sleeve, preventing the connecting sleeve from rotating and thus locking the adjusting rod. Therefore, the overall structural design is reasonable and the operation is convenient.

[0008] Furthermore, the support structure includes a first convex ring and a second convex ring. The first convex ring is formed on the outer peripheral wall of the locking sleeve, and the second convex ring is formed on the inner peripheral wall of the connecting sleeve. The outer diameter of the first convex ring is not less than the inner diameter of the second convex ring.

[0009] The advantages of the above technical solution are as follows: During the upward pulling of the connecting sleeve, the second convex ring moves from the lower side of the first convex ring to the upper side of the first convex ring. After the connecting sleeve is released, the first convex ring can support the second convex ring, thereby enabling the connecting sleeve to be rotatably supported on the locking sleeve. The structural design is simple and reasonable.

[0010] Furthermore, the locking sleeve includes a first ring portion, wherein the first convex ring is formed on the outer peripheral wall surface of the first ring portion.

[0011] The advantages of the above technical solution are: by setting a first ring portion on the locking sleeve and forming a first convex ring on the first ring portion, the forming position of the first convex ring is reasonable, which ensures the reliable use of the locking sleeve.

[0012] Furthermore, the twist cap is made of a deformable material, and the outer wall surface of the first convex ring is arc-shaped.

[0013] The advantages of the above technical solution are: the torsion cap made of deformable material has a certain deformation capacity, and the outer wall of the first convex ring is set in an arc shape, which facilitates the up and down movement of the connecting sleeve. Under the premise of ensuring reliable use, the operator's operation is less strenuous, the use effect is better, and the structural design is reasonable.

[0014] Furthermore, the adjustment assembly also includes an elastic element, the lower end of which is connected to the upper end of the second convex ring, and the upper end of which is connected to the lower end of the torsion cap.

[0015] The advantages of the above technical solution are: pulling the connecting sleeve will compress the elastic element under the action of the second convex ring, resulting in a good operating feel. After adjustment, the limiting fit between the lower end of the connecting sleeve and the locking sleeve will be more reliable under the action of the elastic element, and the structural design is reasonable.

[0016] Furthermore, the circumferential side of the twist cap is provided with a first connecting portion, and the upper inner wall of the connecting sleeve is provided with a corresponding first snap-fit ​​portion. The first snap-fit ​​portion is movably snapped onto the first connecting portion. The locking sleeve also includes a second ring portion. The circumferential side of the second ring portion is provided with a second connecting portion, and the lower inner wall of the connecting sleeve is provided with a corresponding second snap-fit ​​portion. The second snap-fit ​​portion is movably snapped onto the second connecting portion.

[0017] The advantages of the above technical solution are as follows: the connecting sleeve is positioned on the torsion cap by the cooperation of the first snap-fit ​​part and the first connecting part. When the connecting sleeve and the locking sleeve do not form a limiting cooperation, the rotation of the connecting sleeve will drive the torsion cap to rotate. The connecting sleeve is positioned on the locking sleeve by the cooperation of the second snap-fit ​​part and the second connecting part, thereby forming a rotation lock on the torsion cap.

[0018] Furthermore, the first connecting part is composed of several straight first protrusions, which are evenly distributed on the peripheral side of the twist cap. The surface of the first protrusion is arc-shaped. An arc-shaped first groove is formed between two adjacent first protrusions on the peripheral side of the twist cap. The first engaging part is composed of several straight first toothed posts, which are evenly distributed on the inner wall of the connecting sleeve. The first toothed posts are slidably engaged inside the first groove.

[0019] The advantages of the above technical solution are: the first connecting part and the first snap-fit ​​part will slide up and down in a limiting fit, and during the rotation of the connecting sleeve, the first connecting part and the first snap-fit ​​part are not prone to circumferential misalignment, and the fit is simple, reasonable and reliable.

[0020] Furthermore, the second connecting part is composed of several straight second protrusions, which are evenly distributed on the peripheral side surface of the second ring part. The surface of the second protrusion is arc-shaped. An arc-shaped second groove is provided on the peripheral side surface of the second ring part between two adjacent second protrusions. The second engaging part is composed of several straight second toothed posts, which are evenly distributed on the lower inner wall surface of the connecting sleeve. The second toothed posts are slidably engaged inside the second groove.

[0021] The advantages of the above technical solution are: the second connecting part and the second snap-fit ​​part will slide up and down in a limiting fit, and when the locking sleeve and the connecting sleeve form a limiting fit, the second connecting part and the second snap-fit ​​part are not prone to circumferential misalignment, and the fit is simple, reasonable and reliable.

[0022] Furthermore, the second ring portion is provided with a first conical surface, the second connecting portion is provided on the first conical surface, the lower end inner wall surface of the connecting sleeve is provided with a second conical surface, the second conical surface cooperates with the first conical surface, and the second snap-fit ​​portion is provided on the second conical surface.

[0023] The advantages of the above technical solution are: by setting the second connecting part on the first conical surface and the second snap-fit ​​part on the second conical surface, the second connecting part and the second snap-fit ​​part can achieve accurate, reliable and fast limiting fit through the setting of the first conical surface and the second conical surface, and the structural design is reasonable.

Detailed Implementation

[0033] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0034] Please see Figures 1 to 8As shown, a convenient-to-operate air valve regulating assembly is mounted on an air valve body 1. The regulating assembly includes a valve core 2, an regulating rod 3, a torsion cap 4, and a connecting sleeve 5. The air valve body 1 has an air outlet, and the valve core 2 has an air inlet. A vent hole is formed in the middle of the valve core 2, which mates with the air outlet and communicates with the inner cavity of the air valve body 1. A gap exists between the outer surface of the valve core 2 where the vent hole is located and the inner wall of the air valve body 1 to facilitate communication between the inner cavity of the air valve body 1 and the inner cavity of the valve core 2 through the vent hole. A locking sleeve 6 is fixedly installed at the top of the valve core 2. The adjusting rod 3 is threadedly connected to the inner cavity of the locking sleeve 6. The lower end of the adjusting rod 3 extends into the inner cavity of the valve core 2. The lower end of the adjusting rod 3 is tapered, so that when the adjusting rod 3 extends into the air inlet, the gas passage between the adjusting rod 3 and the inner wall of the air inlet gradually decreases, thus slowing down the gas flow rate. The upper end of the adjusting rod 3 is fixedly connected to the torsion cap 4. The upper end of the connecting sleeve 5 is limited and fitted onto the torsion cap 4, thereby driving the torsion cap 4 to rotate through the connecting sleeve 5. The lower end of the connecting sleeve 5 can be limited and fitted onto the locking sleeve 6, thereby restricting the rotation of the connecting sleeve 5. There is also a connection between the connecting sleeve 5 and the locking sleeve 6. The support structure, after the lower end of the connecting sleeve 5 is released from the limiting position of the locking sleeve 6, allows the connecting sleeve 5 to be rotatably supported on the locking sleeve 6. In this structure, when it is necessary to turn the adjusting rod 3, the connecting sleeve 5 is pulled upward, releasing the limiting position of the lower end of the connecting sleeve 5 from the locking sleeve 6, allowing the connecting sleeve 5 to rotate. At the same time, the upper end of the connecting sleeve 5 forms a limiting engagement with the torsion cap 4, thereby driving the torsion cap 4 to rotate. In turn, the torsion cap 4 drives the adjusting rod 3 to rotate, allowing the adjusting rod 3 to adjust the flow rate. Furthermore, due to the setting of the support structure, the connecting sleeve 5 is also rotatably supported on the locking sleeve 6. The purpose of locking sleeve 6, more specifically, is that after the support structure is engaged, the lower end of connecting sleeve 5 will not form a limiting engagement with locking sleeve 6. However, the upper end of connecting sleeve 5 will maintain a limiting engagement with torsion cap 4. Therefore, the operator does not need to pull on connecting sleeve 5 during the rotation process. After adjustment, the operator applies the connecting sleeve 5 again to release the support structure engagement, and the lower end of connecting sleeve 5 and locking sleeve 6 will form a limiting engagement again, thus preventing the connecting sleeve 5 from rotating and achieving the adjustment and locking of adjusting rod 3. Therefore, the overall structure design is reasonable and the operation is convenient.

[0035] In this embodiment, the support structure includes a first convex ring 7 and a second convex ring 8. The first convex ring 7 is formed on the outer peripheral wall of the locking sleeve 6, and the second convex ring 8 is formed on the inner peripheral wall of the connecting sleeve 5. The outer diameter of the first convex ring 7 is not smaller than the inner diameter of the second convex ring 8. In the above structure, during the upward pulling of the connecting sleeve 5, the second convex ring 8 moves from the lower side relative to the first convex ring 7 to the upper side of the first convex ring 7. After the connecting sleeve 5 is released, because the outer diameter of the pressing convex ring 7 is larger, the first convex ring 7 can provide support for the second convex ring 8, thereby enabling the connection... The sleeve 5 is rotatably supported on the locking sleeve 6. The structure is simple and reasonable. It needs to be explained that after the adjustment is completed, the connecting sleeve 5 is pressed down, and the second convex ring 8 moves from the upper side relative to the first convex ring 7 to the lower side of the first convex ring 7. After the connecting sleeve 5 and the locking sleeve 6 form a limiting fit, the connecting sleeve 5 is released, and the adjustment is completed. Alternatively, by designing the position of the second convex ring 8, when the second convex ring 8 is located on the lower side of the first convex ring 7, the first convex ring 7 can abut against the second convex ring 8, thereby ensuring that the connecting sleeve 5 and the locking sleeve 6 maintain a reliable limiting fit.

[0036] In this embodiment, the locking sleeve 6 includes a first ring portion 9 and a first protruding ring 7 formed on the outer peripheral wall surface of the first ring portion 9. In the above structure, by providing the first ring portion 9 on the locking sleeve 6 and forming the first protruding ring 7 on the first ring portion 9, the forming position of the first protruding ring 7 is reasonable, ensuring the reliable use of the locking sleeve 6.

[0037] In this embodiment, the twist cap 4 is made of a deformable material, and the outer wall of the first convex ring 7 is arc-shaped. More specifically, the twist cap 4 can be made of plastic. In the above structure, the twist cap 4 made of deformable material has a certain deformation capability. Thus, during the movement, under the action of the first convex ring 7, the second convex ring 8 can be stretched and deformed. After moving into place, the twist cap 4 recovers its deformation, and the outer wall of the first convex ring 7 is also arc-shaped. The movement of the twist cap 4 will be smoother, thereby facilitating the up and down movement of the connecting sleeve 5. Under the premise of ensuring reliable use, the operator's operation is less strenuous, the use effect is better, and the structural design is reasonable.

[0038] In another embodiment, the adjustment assembly further includes an elastic element 10. The lower end of the elastic element 10 is connected to the upper end of the second convex ring 8, and the upper end of the elastic element 10 is connected to the lower end of the torsion cap 4. The elastic element 10 can be a spring. In the above structure, pulling the connecting sleeve 5 will compress the elastic element 10 under the action of the second convex ring 8, resulting in a good operating feel. After adjustment, under the action of the elastic element 10, the limiting fit between the lower end of the connecting sleeve 5 and the locking sleeve 6 will be more reliable, and the structural design is reasonable.

[0039] In the above embodiment, the circumferential side of the twist cap 4 is provided with a first connecting part 11, and the upper inner wall of the connecting sleeve 5 is provided with a corresponding first snap-fit ​​part 12. The first snap-fit ​​part 12 is movably snapped onto the first connecting part 11. The locking sleeve 6 also includes a second ring part 13, which is arranged below the first ring part 9. The circumferential side of the second ring part 13 is provided with a second connecting part 14, and the lower inner wall of the connecting sleeve 5 is provided with a corresponding second snap-fit ​​part 15. The second snap-fit ​​part 15 is movably snapped onto the second connecting part 14. In the above structure, the connecting sleeve 5 is positioned on the twist cap 4 by the cooperation of the first snap-fit ​​part 12 and the first connecting part 11. When the connecting sleeve 5 and the locking sleeve 6 do not form a limiting cooperation, the twist cap 4 will rotate when the connecting sleeve 5 rotates. The connecting sleeve 5 is positioned on the locking sleeve 6 by the cooperation of the second snap-fit ​​part 15 and the second connecting part 14, thereby forming a rotational lock on the twist cap 4 (the locking sleeve 6 is fixed on the valve core 2).

[0040] In the above embodiment, the first connecting part 11 is composed of several straight first protrusions, which are evenly distributed on the peripheral side of the twist cap 4. The surface of the first protrusion is arc-shaped. An arc-shaped first groove 16 is provided between two adjacent first protrusions on the peripheral side of the twist cap 4. The first engaging part 12 is composed of several straight first toothed posts, which are evenly distributed on the inner wall of the connecting sleeve 5. The first toothed posts slide and engage inside the first groove 16. In the above structure, the first connecting part 11 and the first engaging part 12 will slide and limit each other in an up-and-down sliding fit. During the rotation of the connecting sleeve 5, the first connecting part 11 and the first engaging part 12 are not prone to circumferential misalignment. The fit is simple, reasonable and reliable. It should be noted that the first engaging part 12 is always located on the first connecting part 11 during the entire adjustment process.

[0041] In the above embodiment, the second connecting part 14 is composed of a plurality of straight second protrusions, which are evenly distributed on the peripheral side surface of the second ring part 13. The surface of the second protrusion is arc-shaped. An arc-shaped second groove 17 is provided between two adjacent second protrusions on the peripheral side surface of the second ring part 13. The second engaging part 15 is composed of a plurality of straight second toothed posts, which are evenly distributed on the lower inner wall surface of the connecting sleeve 5. The second toothed posts slide and engage inside the second groove 17. In the above structure, the second connecting part 14 and the second engaging part 15 will slide and limit each other in an up-and-down sliding fit. When the locking sleeve 6 and the connecting sleeve 5 form a limit fit, the second connecting part 14 and the second engaging part 15 are not prone to circumferential misalignment. The fit is simple, reasonable and reliable.

[0042] In the above implementation, the second ring portion 13 is provided with a first conical surface 18, the second connecting portion 14 is provided on the first conical surface 18, the lower end inner wall surface of the connecting sleeve 5 is provided with a second conical surface 19, the second conical surface 19 cooperates with the first conical surface 18, and the second snap-fit ​​portion 15 is provided on the second conical surface 19. In the above structure, the second connecting portion 14 is provided on the first conical surface 18, and the second snap-fit ​​portion 15 is provided on the second conical surface 19. Through the provision of the first conical surface 18 and the second conical surface 19, the second connecting portion 14 and the second snap-fit ​​portion 15 can achieve accurate, reliable, and fast limiting cooperation, and the structural design is reasonable.

[0043] In the above embodiment, the locking sleeve 6 is fixed to the top of the valve core 2 by riveting. The locking sleeve 6 also includes a third ring 20, which is positioned below the second ring 13. A riveting boss 21 is provided on the outer periphery of the third ring 20. Third toothed columns can be evenly arranged on the outer peripheral wall of the riveting boss 21. A riveting ring edge 22 is provided at the upper end of the valve core 2. The riveting ring edge 22 forms a riveting cavity around the valve core 2. The third ring 20 cooperates with the riveting cavity. The riveting ring edge 22 is squeezed by an external riveting tool, causing the top of the riveting ring edge 22 to deform, thereby fixing the riveting ring edge 22 to the riveting boss 21.

[0044] In another embodiment, the valve core 2 and the locking sleeve 6 are integrally formed. The locking sleeve 6 is only provided with a first ring 9 and a second ring 13. The integral forming shortens the assembly period of the parts and improves the overall strength and durability of the parts.

[0045] In another embodiment, the connection between each second protrusion and the outer surface of the locking sleeve 6 consists of two inclined straight lines, and the two straight lines on each second protrusion approach each other from one end near the valve body 1 to the other end, so that the two sides of each second groove are also inclined straight lines. The shape of the second toothed post is adapted to the shape of the second groove. In the above structure, when the second snap-fit ​​part 15 slides onto the second connecting part 14, since the sides of the second toothed post and the second groove are both inclined, the second groove automatically guides the second toothed post so that the second toothed post can automatically align on the second groove.

[0046] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
