It includes a mounting base with multiple grooves on its upper surface.

Description

Technical Field

[0001] This utility model relates to the field of vibration flow controller technology, specifically to a damping and shock absorption installation structure for an anti-vibration flow controller. Background Technology

[0002] Vibrations occur in many situations during industrial production, such as the operation of mechanical equipment and the pulsation of fluids in pipelines. As a key device for accurately controlling fluid flow, flow controllers have high requirements for the stability of the operating environment.

[0003] Traditional flow controllers are typically installed in a simple manner, directly fixed to the mounting base or pipe with bolts. This installation method cannot effectively isolate external vibrations, which can easily be transmitted to the flow controller's interior, affecting the normal operation of its precision components. Vibration can cause displacement or deformation of the flow controller's measuring elements, leading to increased measurement errors and affecting the accuracy of flow control. Long-term vibration can also cause loosening and wear of internal components of the flow controller, and even cause malfunctions, reducing the service life of the equipment. Utility Model Content

[0004] In view of the problems existing in the damping and vibration reduction installation structure of the above-mentioned anti-vibration flow controller, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a damping and vibration-damping installation structure for a vibration-resistant flow controller, solving the problem that the installation method of flow controllers is usually quite simple, directly fixing them to the mounting base or pipe with bolts. This installation method cannot effectively isolate external vibrations, causing vibrations to easily be transmitted to the inside of the flow controller, affecting the normal operation of its internal precision components.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A damping and shock-absorbing mounting structure for a vibration-resistant flow controller includes a mounting base. The upper surface of the mounting base has multiple grooves, and a shock-absorbing spring is fixedly connected to the upper surface of each groove. A fixing seat is fixedly connected to the upper surface of each shock-absorbing spring. The upper surface of the fixing seat also has a groove, and the flow controller body is fixedly intercepted inside each groove. First cavities are formed on both sides of the mounting groove, and fixing mechanisms are installed inside both first cavities. A second cavity is formed below each mounting groove, and a buffer mechanism is installed inside each cavity.

[0008] Preferably, the fixing mechanism includes two movable plates, two lead screws, two knobs, and multiple inserts. Each of the two first cavities has an internal threaded hole on one side. Each lead screw is disposed inside the corresponding internal threaded hole. Each knob is fixedly connected to one end of the corresponding lead screw. Each movable plate is slidably disposed inside the corresponding first cavity. The two lead screws are rotatably connected to one side of the corresponding movable plate. Each insert is fixedly connected to one side of the corresponding movable plate.

[0009] Preferably, the buffer mechanism includes a connecting rod and a piston. The piston is slidably and sealingly disposed inside the corresponding second cavity. A sealing hole is provided between each second cavity and the groove. Each connecting rod is slidably and sealingly disposed inside the corresponding sealing hole. Each connecting rod is fixedly connected to the upper surface of the corresponding piston. Each connecting rod is fixedly connected to the lower surface of the fixed seat. The surface of the piston is provided with multiple micropores.

[0010] Preferably, a rubber cushioning pad is fixedly connected to the upper surface of the mounting base.

[0011] Preferably, the lower surface of the mounting base is provided with an arc-shaped mounting plate, and both sides of the mounting base and the arc-shaped mounting plate are fixedly connected with fixing plates, and two bolts are provided between each pair of corresponding fixing plates.

[0012] Preferably, two slots are provided on both sides of the flow controller body, and the two slots are respectively matched with corresponding plugs.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model absorbs vibration energy through the elastic deformation of a shock-absorbing spring and attenuates high-frequency vibrations with a rubber buffer pad, forming the first shock-absorbing barrier. The buffer mechanism utilizes the gas damping effect when the piston slides in the second cavity to convert vibration kinetic energy into heat energy, thus delaying vibration transmission. The multi-stage shock-absorbing structure works synergistically to effectively isolate the transmission of external vibrations to the flow controller body, reducing displacement, deformation, and measurement errors of internal precision components caused by vibration, thereby improving the accuracy and stability of flow control.

[0015] 2. This utility model uses the threaded transmission of the lead screw and the insert block to firmly clamp the flow controller body in the groove of the fixed seat. The self-locking characteristic of the lead screw avoids the loosening problem of traditional bolt fixing, ensuring the stability of the controller in a vibration environment. The cooperation between the insert block and the slot provides a reliable rigid connection, preventing the controller from shifting or falling off due to vibration, and ensuring the reliability of the equipment's long-term operation.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a damping and vibration reduction installation structure for an anti-vibration flow controller.

[0024] This utility model provides, for example Figure 1-3 The damping and shock absorption mounting structure of the vibration-resistant flow controller shown includes a mounting base 1. The upper surface of the mounting base 1 has multiple grooves. A shock-absorbing spring 2 is fixedly connected to the upper surface of each groove. A fixing seat 3 is fixedly connected to the upper surface of each shock-absorbing spring 2. The upper surface of the fixing seat 3 has grooves. The flow controller body 4 is fixedly intercepted inside the grooves. A first cavity is opened on both sides of the mounting groove. A fixing mechanism is set inside the two first cavities. A second cavity is opened below each mounting groove. A buffer mechanism is set inside each cavity. A rubber buffer pad 11 is fixedly connected to the upper surface of the mounting base 1.

[0025] Multiple shock-absorbing springs 2 on the mounting base 1 support the fixed seat 3. When external vibration is transmitted to the mounting base, the springs absorb the vibration energy through elastic deformation, reducing the transmission of vibration to the fixed seat. The rubber buffer pad 11 on the upper surface of the mounting base further attenuates high-frequency vibration through flexible material, forming the first shock-absorbing barrier and reducing the direct impact of vibration on the flow controller body 4.

[0026] To fix the flow controller body 4, such as Figure 1-3 As shown, the fixing mechanism includes two movable plates 5, two lead screws 6, two knobs 7, and multiple inserts 8. Each of the two first cavities has an internal threaded hole on one side. Each lead screw 6 is respectively set inside the corresponding internal threaded hole. Each knob 7 is respectively fixedly connected to one end of the corresponding lead screw 6. Each movable plate 5 is slidably set inside the corresponding first cavity. The two lead screws 6 are respectively rotatably connected to one side of the corresponding movable plate 5. Each insert 8 is respectively fixedly connected to one side of the corresponding movable plate 5. Two slots are opened on both sides of the flow controller body 4, and the two slots are respectively matched with the corresponding inserts 8.

[0027] Rotating knob 7 drives lead screw 6 to rotate, which in turn moves moving plate 5 and insert block 8, inserting the insert block into the slot of flow controller body 4. The threaded drive provides a stable clamping force, ensuring that the controller is rigidly fixed in the groove of the fixing seat 3. This rigid connection not only reduces vibration but also prevents the controller from shifting due to vibration. Combined with the self-locking characteristic of the lead screw, it avoids the loosening problems that may occur with traditional bolt fixing.

[0028] To further improve earthquake resistance, such as Figure 1-2 As shown, the buffer mechanism includes a connecting rod 9 and a piston 10. The piston 10 is slidably disposed inside the corresponding second cavity. A sealing hole is provided between each second cavity and the groove. Each connecting rod 9 is slidably disposed inside the corresponding sealing hole. Each connecting rod 9 is fixedly connected to the upper surface of the corresponding piston 10. Each connecting rod 9 is fixedly connected to the lower surface of the fixing seat 3. Multiple micropores are provided on the surface of the piston 10.

[0029] The fixed seat 3 is connected to the piston 10 via the connecting rod 9. When the fixed seat is vibrated, the connecting rod drives the piston to slide in the second cavity. The micropores on the piston surface cause a damping effect when the gas in the cavity passes through, converting the vibration kinetic energy into heat energy and slowing down the vibration transmission speed.

[0030] To facilitate the installation of this device, such as Figure 1-2 As shown, an arc-shaped mounting plate 12 is provided on the lower surface of the mounting base 1. Fixing plates 13 are fixedly connected to both sides of the mounting base 1 and the arc-shaped mounting plate 12, and two bolts 14 are provided between the two corresponding fixing plates 13.

[0031] The mounting base 1 is fixed to the equipment or pipeline by the arc-shaped mounting plate 12 and the fixing plate 13. The arc design can adapt to the mounting surface with different curvatures. The bolt 14 provides adjustable installation tension. This structure flexibly connects the mounting base to the pipeline, reduces the rigid transmission path, and allows for a certain angle of installation adjustment, thereby improving the applicability of the equipment.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
