Abstract
Description
Technical Field
[0001] This application relates to the field of throttling devices, and more particularly to a pipeline throttling device. Background Technology
[0002] A throttle valve is a type of valve that regulates fluid flow and pressure by changing the cross-sectional area of the fluid passage. Traditional throttle valves typically have a throttling orifice inside the base to reduce the cross-sectional area of the fluid passage. Both ends of this type of throttle valve have threaded structures for connecting to pipes.
[0003] In actual installation, for this type of threaded connection structure, the throttle valve must first be installed on one end of the pipe, and then the other end of the pipe is rotated to connect it to the throttle valve. However, when the pipe dimensions at both ends of the throttle valve differ significantly, or when other branch pipes are connected to the pipes at both ends, the throttle valve is difficult to install directly between the two pipes. Utility Model Content
[0004] To simplify the installation process of throttling devices on pipelines and facilitate their installation on complex pipelines, this application provides a pipeline throttling device.
[0005] The pipeline throttling device provided in this application adopts the following technical solution:
[0006] A pipe throttling device includes a cylindrical body. A first connector and a second connector are interconnected within the cylindrical body. The first connector and the second connector are used for threaded connection to a target pipeline. A retaining ring is fixedly connected to the inner wall of one end of the cylindrical body. A protruding ridge for abutting the retaining ring is fixedly connected to the outer wall of the first connector. The second connector is threaded into the cylindrical body and abuts against the first connector. A throttling plate is provided between the first connector and the second connector within the cylindrical body, and a through hole is formed on the throttling plate.
[0007] By adopting the above technical solution, a first connector and a second connector are interconnected inside the cylinder. The first connector is initially positioned using the cooperation of a retaining ring and a convex ridge. The second connector is threaded into the cylinder and abuts against the first connector, ensuring the overall stability of the throttling device. A throttling plate with a through-hole is installed between the first and second connectors. Because the cross-sectional area of the through-hole is smaller than the cross-sectional area of the pipe, the fluid passing through the device is throttled, meeting the flow regulation requirements of the pipeline system. The first and second connectors are threaded onto their respective pipes without requiring rotation of the pipes at both ends of the cylinder, thus facilitating the operator's connection of the throttling valve between two complex pipes.
[0008] Optionally, both the first connector and the second connector have a sealing ring at the end facing the throttle plate.
[0009] By adopting the above technical solution, a sealing ring is set at the end of the first connector and the second connector facing the throttling plate, which can effectively prevent fluid from leaking from the gap between the connector and the throttling plate, improve the sealing performance of the device, ensure that the fluid flows in the device according to the predetermined path, guarantee the throttling effect and the normal operation of the pipeline system, and avoid energy loss and safety hazards caused by leakage.
[0010] Optionally, both the first connector and the second connector are provided with positioning grooves for limiting the sealing ring.
[0011] By adopting the above technical solution, limiting grooves are provided on the first and second connectors to limit the movement of the sealing ring, ensuring that the sealing ring will not shift during installation and use. This ensures that the sealing ring is always in the correct sealing position, further enhancing the reliability of the seal, extending the service life of the sealing ring, reducing the risk of leakage caused by sealing ring displacement, and improving the overall performance and stability of the device.
[0012] Optionally, the throttling plate has chamfers at both ends of the through hole.
[0013] By adopting the above technical solution, chamfering is provided at both ends of the through-hole of the throttling plate, which reduces the resistance of the fluid when passing through the through-hole. When the fluid encounters the chamfer during flow, the flow state is smoother, reducing eddies and energy loss caused by sudden changes in cross-section, and making the fluid flow more smoothly.
[0014] Optionally, a mounting groove is provided on one side of the throttle plate, and an adjustment seat is provided in the mounting groove. The first connector or the second connector limits the adjustment seat to be located in the mounting groove.
[0015] The adjusting seat is provided with an adjusting hole. The adjusting seat can be adjusted in position within the mounting groove and the overlapping area between the mounting groove and the adjusting hole can be adjusted. An adjusting component is provided between the adjusting seat and the throttle plate. The adjusting component is used to limit the relative position of the adjusting seat within the mounting groove.
[0016] By adopting the above technical solution, an installation groove is set on one side of the throttling plate, and an adjusting seat is set in the installation groove. The adjusting seat is confined within the installation groove by a first connector or a second connector. The adjusting seat is provided with an adjusting hole, and the position of the adjusting seat can be adjusted within the installation groove, thereby changing the overlapping area between the installation groove and the adjusting hole. This design allows the operator to flexibly adjust the throttling area according to actual working conditions, thereby adjusting the throttling effect, meeting the fluid flow control requirements in different scenarios, and improving the versatility and adaptability of the device.
[0017] Optionally, the adjusting seat is disposed in the mounting groove, and the adjusting seat is rotatably disposed in the mounting groove. The adjusting component includes a limiting block, which is mounted on one of the two components, the throttle plate and the adjusting seat. The other component is provided with a plurality of limiting grooves for matching the limiting block. By rotating the adjusting seat, the limiting block is inserted into different limiting grooves, so as to adjust the overlapping area between the mounting groove and the adjusting hole.
[0018] By adopting the above technical solution, the adjusting seat is configured to rotate within the mounting groove, and its relative position within the mounting groove is limited by adjusting components, namely, the limiting block and the limiting groove. Rotating the adjusting seat allows the limiting block to engage with different limiting grooves, thereby adjusting the overlapping area between the mounting groove and the adjusting hole. This adjustment method is simple and convenient to operate, enabling quick and accurate adjustment of the throttling area, improving the operability and adjustment precision of the device, and allowing operators to more easily control the throttling effect.
[0019] Optionally, a plurality of through holes are provided on the bottom wall of the mounting groove, and when the adjusting seat is adjusted relative to the mounting groove, the adjusting hole can be controlled to coincide with one or more of the through holes.
[0020] By adopting the above technical solution, several through holes are set on the bottom wall of the mounting groove, and when the adjusting seat is adjusted relative to the mounting groove, the adjusting hole can be controlled to coincide with one or more through holes. Since each through hole is the same size and has the same cross-sectional area for gas flow, the operator can precisely control the number of overlapping adjusting holes with through holes to achieve fine adjustment of the airflow area passing through the throttling device. This design further enhances the adjustability of the throttling effect, better meets the precise flow and pressure control requirements of different pipeline systems, and improves the performance and application range of the throttling device.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The first connector is inserted into the sleeve, and the second connector is threaded into the sleeve and presses the throttle plate against the first connector. Both the first connector and the second connector are connected to the corresponding pipeline by means of threaded connection. This connection method does not require rotating the pipeline at both ends of the cylinder, thus making it convenient for the operator to connect the throttle valve between two complex pipelines.
[0023] 2. By setting an adjustable seat, the overlapping area between the mounting groove and the adjustment hole can be easily adjusted, thereby realizing flexible adjustment of the fluid flow rate in the pipeline and meeting the flow requirements under different working conditions;
[0024] 3. By setting multiple through holes and enabling the regulating seat to control the overlap of the regulating hole with different numbers of through holes, more precise flow regulation can be achieved, improving the accuracy of flow control. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail. Example 1
[0036] This application discloses a pipeline throttling device. For example... Figure 1-3 The pipe throttling device includes a cylindrical body 1, inside which are a first connector 11 and a second connector 12 connected to each other. A retaining ring 13 is fixedly connected to the inner wall of one end of the cylindrical body 1. A protruding rib 14 for abutting against the retaining ring 13 is fixedly connected to the outer wall of the first connector 11. The abutting between the protruding rib 14 and the retaining ring 13 achieves the initial positioning of the first connector 11 at one end of the cylindrical body 1. The second connector 12 is threaded into the cylindrical body 1 and abuts against the first connector 11, thereby firmly fixing the first connector 11 and the second connector 12 inside the cylindrical body 1. The first connector 11 and the second connector 12 are provided with threads for connecting to the pipe.
[0037] A throttling plate 15 is provided between the first connector 11 and the second connector 12. The throttling plate 15 has a through hole 16. When fluid passes through the through hole 16, the cross-sectional area of the through hole 16 is smaller than that of the pipe, thus achieving a throttling effect. To enhance sealing performance, a sealing ring 17 is provided at the end of both the first connector 11 and the second connector 12 facing the throttling plate 15. The sealing ring 17 effectively prevents fluid leakage from the gap between the connector and the throttling plate 15. Simultaneously, both the first connector 11 and the second connector 12 are provided with positioning grooves 18 to limit the position of the sealing ring 17, ensuring that the sealing ring 17 will not shift during installation and use, thus guaranteeing the reliability of the seal.
[0038] In addition, the throttling plate 15 has chamfers at both ends of the through hole 16. The chamfers can reduce the resistance of the fluid when passing through the through hole 16, making the fluid flow smoother and reducing energy loss.
[0039] The implementation principle of this embodiment is as follows: In practical applications, the pipe throttling device is installed in a pipeline system. Fluid enters from one end of the cylinder 1, passes through the first connector 11, and then is throttled through the through hole 16 on the throttling plate 15, finally flowing out from the second connector 12. The presence of the sealing ring 17 ensures the sealing of the fluid within the device, preventing leakage; the chamfer optimizes the fluid flow state and improves the operating efficiency of the throttling device. Example 2
[0040] Reference Figure 4-6The difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the throttle plate 15 has a mounting groove 2 on one side, and an adjusting seat 21 is provided in the mounting groove 2. A first connector 11 or a second connector 12 confines the adjusting seat 21 within the mounting groove 2. In this embodiment, the mounting groove 2 on the throttle plate 15 faces the first connector 11, which confines the adjusting seat 21 within the mounting groove 2. The adjusting seat 21 has an adjusting hole 22, allowing its position to be adjusted within the mounting groove 2, thereby adjusting the overlapping area between the mounting groove 2 and the adjusting hole 22. To limit the relative position of the adjusting seat 21 within the mounting groove 2, an adjusting assembly is provided between the adjusting seat 21 and the throttle plate 15.
[0041] Specifically, the adjusting seat 21 is rotatably disposed within the mounting slot 2. The adjusting assembly includes a limiting block 23, which is mounted on one of the two components, the limiting block 23 and the throttle plate 15. The other component is provided with several limiting slots 24 for the limiting block 23 to be inserted into.
[0042] In this embodiment, the limiting block 23 is installed on the throttle plate 15, and several limiting grooves 24 are provided on the adjusting seat 21. By rotating the adjusting seat 21, the limiting block 23 is inserted into different limiting grooves 24, thereby adjusting the overlapping area between the mounting groove 2 and the adjusting hole 22. Example 3
[0043] Reference Figure 7-9 The difference between Embodiment 3 and Embodiment 2 is that several through holes 16 of the same size are evenly distributed on the bottom wall of the mounting groove 2, and the cross-sectional area of each through hole 16 for gas flow is the same. When the position of the adjusting seat 21 relative to the mounting groove 2 is adjusted, the number of overlaps between the adjusting hole 22 and the through hole 16 can be precisely controlled.
[0044] For example, when a piping system requires a greater throttling effect, the operator can rotate the regulating seat 21 to a specific position so that the regulating orifice 22 overlaps with only a small number of through holes 16. This significantly reduces the cross-sectional area through which the fluid passes, increases the flow velocity, and lowers the pressure, thereby effectively enhancing the throttling effect.
[0045] Conversely, when the piping system requires a smaller throttling effect, i.e., when it is desired that the fluid can pass through more smoothly, the operator can rotate the regulating seat 21 to a position where the regulating hole 22 coincides with a larger number of through holes 16. At this time, the cross-sectional area through which the fluid passes increases, the flow velocity relatively slows down, the pressure loss decreases, and the throttling effect is correspondingly weakened.
[0046] With this adjustment method, the operator can flexibly control the number of overlaps between the adjustment hole 22 and the through hole 16 according to the actual working conditions, thereby adjusting the area through which the airflow passes through the throttling device, achieving precise control over the throttling effect, and meeting the usage requirements in different scenarios.
[0047] In actual use, depending on the different fluid flow requirements of the pipeline system, the operator can rotate the adjusting seat 21 to change the overlap between the adjusting hole 22 and the through hole 16, so as to flexibly adjust the throttling effect and meet the usage requirements under different working conditions.
[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
