Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a multifunctional regulating valve. Background Technology

[0002] A multi-functional control valve is a type of valve that integrates multiple control functions, enabling precise control of parameters such as flow rate, pressure, and temperature of fluid media. This type of valve typically consists of a valve body, valve disc, valve stem, pneumatic actuator, and control system. By receiving external input signals (such as compressed air or electrical signals), it drives the valve disc to actuate, thereby changing the flow area between the valve disc and the valve seat, thus regulating the flow rate of the medium.

[0003] Control valves are connected to pipelines primarily through flange connections, threaded connections, and welding. Flange connections are commonly used for large-diameter pipelines, secured with bolts to ensure reliable sealing; threaded connections are suitable for small-diameter or temporary connections, offering easy installation; welding is used in special operating conditions such as high temperature and high pressure, providing high strength and sealing performance.

[0004] In the existing technology, the installation process of control valves when connected to pipelines is complicated and demanding. It is necessary to ensure that the connection is firm and the seal is reliable, otherwise leakage or vibration problems may occur. Furthermore, when the connection is temporarily disconnected, not only must one end be removed, but the other end must also be blocked in time to prevent leakage. Therefore, a multi-functional control valve is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-functional regulating valve, which aims to improve the problems of complex and demanding installation of regulating valves when connecting to pipelines, the need to ensure a firm connection, and the need to promptly block the other end when the connection is temporarily disconnected.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-functional regulating valve includes a control valve and a connecting pipe. The inner wall of the connecting pipe is fixedly connected to one end of the control valve. A spring is fixedly connected to the inner wall of the connecting pipe. A fixed pipe is fixedly connected to the outside of the connecting pipe. An intermediate pipe is slidably connected to the inner wall of the fixed pipe. A threaded pipe is slidably connected to the outside of the intermediate pipe. A delivery pipe is fixedly connected to the inner wall of the threaded pipe. A small ball is movably connected to the inner wall of the threaded pipe. A spring is fixedly connected to the inner wall of the delivery pipe. The outside of the small ball is in contact with the other end of the spring. A fastening assembly for securing the pipe connection is fixedly connected to the other end of the control valve.

[0008] As a further description of the above technical solution:

[0009] The fastening assembly includes a fixing box, and two sliders are slidably connected to the inner wall of the fixing box. The other end of each slider is fixedly connected to a connecting block.

[0010] As a further description of the above technical solution:

[0011] A rotating tube is slidably connected to the outside of the fixed tube, and the inner wall of the rotating tube is threadedly connected to the outside of the threaded tube.

[0012] As a further description of the above technical solution:

[0013] A small ball is movably connected to the inner wall of the fixed tube, and the outside of the small ball is in contact with the other end of the spring.

[0014] As a further description of the above technical solution:

[0015] An intermediate block is fixedly connected to the outside of the intermediate tube, and the other end of the intermediate tube is slidably connected to the inner wall of the fixed tube.

[0016] As a further description of the above technical solution:

[0017] Both connecting blocks have bolts threaded to their inner walls, and the external threads of the two bolts are connected to the inside of the fixing box.

[0018] As a further description of the above technical solution:

[0019] A fastening ring is fixedly connected to the bottom of one of the connecting blocks, and a movable ring is fixedly connected to the bottom of the other connecting block.

[0020] As a further description of the above technical solution:

[0021] The fastening ring is rotatably connected to a connecting rod, the other end of which is fixedly connected to a connecting plate, and the other end of which is fixedly connected to a clamping plate. The clamping plate is externally coupled to the inner wall of the moving ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the reset of spring two causes ball two to make close contact with the outside of the intermediate tube, thereby forming a passage between ball two, intermediate tube, and ball one, allowing liquid or gas to flow. Twisting the rotating tube stabilizes its positional relationship. Removing the threaded tube causes spring one to push ball one to make close contact with the inner wall of the fixed tube, so that the internal substances will not be lost when not connected to the outside.

[0024] 2. In this utility model, the change in the position of the two connecting blocks causes the fastening ring and the moving ring to move closer to each other, thereby strengthening the connection after the pipe is connected. Furthermore, rotating the connecting rod causes the position of the connecting plate to move, which in turn causes the connecting plate to engage with the slot of the moving ring, making the connection more stable. Strengthening the pipe connection of the control valve can significantly improve the stability and sealing of the system, preventing leakage and loosening. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 2This utility model provides an embodiment of a multi-functional regulating valve, including a control valve 1 and a connecting pipe 2. The inner wall of the connecting pipe 2 is fixedly connected to one end of the control valve 1, and a spring 12 is fixedly connected to the inner wall of the connecting pipe 2. To improve sealing and durability, the connecting pipe 2 is made of high-strength stainless steel, ensuring that it can maintain stability and corrosion resistance under high pressure. A fixing pipe 3 is fixedly connected to the outside of the connecting pipe 2, and an intermediate pipe 9 is slidably connected to the inner wall of the fixing pipe 3. When the intermediate pipe 9 slides close to the fixing pipe 3, it connects the interior of the fixing pipe 3 and the threaded pipe 5.

[0034] A threaded pipe 5 is slidably connected to the outside of the intermediate pipe 9. A conveying pipe 6 is fixedly connected to the inner wall of the threaded pipe 5. The position change of the threaded pipe 5 causes the position change of the conveying pipe 6. A small ball 7 (as shown in the attached figure) is movably connected to the inner wall of the threaded pipe 5. Figure 2 The position change of the intermediate tube 9 pushes the position of the small ball 7 backward. A spring 8 is fixedly connected to the inner wall of the conveying tube 6. The outer end of the small ball 7 contacts the other end of the spring 8. The small ball 7 compresses the spring 8, and the spring 8 resets, causing the small ball 7 to form a connection with the intermediate tube 9. A rotating tube 4 is slidably connected to the outside of the fixed tube 3. The inner wall of the rotating tube 4 is threadedly connected to the outside of the threaded tube 5. Twisting the rotating tube 4 causes it to spiral together with the threaded tube 5, thus fixing the docking position.

[0035] A small ball 11 is movably connected to the inner wall of the fixed tube 3, and the outside of the small ball 11 is in contact with the other end of the spring 12 (as shown in the attached figure). Figure 2 The intermediate tube 9 pushes the small ball 11 to change position, and the small ball 11 causes the spring 12 to deform. The return of the spring 12 pushes the small ball 11 to form a channel between the intermediate tube 9 and the small ball 11. An intermediate block 10 is fixedly connected to the outside of the intermediate tube 9 to maintain its intermediate position and prevent it from moving to one side. The other end of the intermediate tube 9 is slidably connected to the inner wall of the fixed tube 3. In order to reduce friction and wear, the surface of the intermediate tube 9 is hardened to increase its wear resistance and extend its service life.

[0036] Reference Figures 3 to 5 The other end of the control valve 1 is fixedly connected to a fastening assembly for securing the pipe connection. Bolts 18 are threaded onto the inner walls of both connecting blocks 17, and the external threads of the two bolts 18 are connected to the inside of the fixing box 15. Tightening the two bolts 18 causes their positions to shift, moving the two connecting blocks 17 closer together or further apart. A fastening ring 13 (as shown in the attached image) is fixedly connected to the bottom of each connecting block 17. Figure 4Another connecting block 17 has a movable ring 14 fixedly connected to its bottom. The movement of the two connecting blocks 17 causes the fastening ring 13 and the movable ring 14 to move closer to each other. To enhance the sealing effect, a high-temperature resistant silicone gasket is used between the fastening ring 13 and the movable ring 14. This material not only has good sealing performance, but can also withstand high temperature changes, preventing leakage problems caused by thermal expansion and contraction.

[0037] A connecting rod 19 is rotatably connected to the outside of the fastening ring 13. The connecting rod 19 is made of titanium alloy, which is both lightweight and sturdy, capable of withstanding large torques without deformation, ensuring operational stability and reliability. A connecting plate 20 is fixedly connected to the other end of the connecting rod 19. Rotating the connecting rod 19 causes the connecting plate 20 to move. A retaining plate 21 is fixedly connected to the other end of the connecting plate 20. The retaining plate 21 is externally coupled to the inner wall of the moving ring 14. The connecting plate 20 causes the retaining plate 21 to engage with the retaining groove of the moving ring 14 (as shown in the attached diagram). Figure 5 This makes the connection more stable.

[0038] Working principle: Moving the position of the threaded tube 5 causes the position of the conveying tube 6 to change. The change in the position of the threaded tube 5 causes the position of the intermediate tube 9 to change. The intermediate tube 9 pushes the position of the small ball 11 to change. The change in the position of the small ball 11 causes the spring 12 to deform. The return of the spring 12 pushes the other end of the small ball 11 to make full contact with the outside of the intermediate tube 9, which in turn pushes the position of the intermediate tube 9 to change. This allows the intermediate tube 9 to push the position of the small ball 7 to change. The change in the position of the small ball 7 causes the spring 28 to deform. The return of the spring 28 causes the small ball 7 to make tight contact with the outside of the intermediate tube 9, thus forming a passage between the small ball 7, the intermediate tube 9, and the small ball 11, allowing liquid or gas to flow. Twisting the rotating tube 4 stabilizes its positional relationship. Removing the threaded tube 5 allows the spring 12 to push the small ball 11 to make tight contact with the inner wall of the fixed tube 3, so that the internal substances will not be lost when not connected to the outside.

[0039] Tightening the two bolts 18 causes their positions to shift, moving the two connecting blocks 17 closer together or further apart. When they move closer, the two sliders 16 slide against the inner wall of the fixed box 15. The shift in position of the connecting blocks 17 also causes the fastening ring 13 and the moving ring 14 to move closer together, reinforcing the pipe connection. Rotating the connecting rod 19 moves the connecting plate 20, causing the clamping plate 21 to engage with the groove of the moving ring 14, making the connection more secure. Reinforcing the pipe connection of the control valve significantly improves the system's stability and sealing, preventing leaks and loosening. The reinforced connection can withstand higher pressure and mechanical stress, reducing the risk of failure due to vibration or temperature changes, thus extending the equipment's service life and ensuring the safety and reliability of fluid transmission.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
