Description

Technical Field

[0001] This utility model relates to the field of boiler instruments, and in particular to a vibration-damping instrument. Background Technology

[0002] During boiler operation, instrument readings are often inaccurate or structurally loosened due to equipment vibration, affecting monitoring accuracy and safety. Existing instrument vibration damping structures mostly use rubber pads or springs for cushioning, but these are prone to aging and failure after long-term use, resulting in unstable vibration damping effects. In addition, resonance still exists between the instrument casing and internal components under complex operating conditions, further reducing its service life.

[0003] Therefore, there is an urgent need for a vibration-resistant instrument with a reliable structure and durable vibration reduction performance to improve its working stability and measurement accuracy in high-vibration environments. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a vibration damping instrument that can: 1. By utilizing the damping effect of the resistance fluid on the display pointer, the swing amplitude of the display pointer is significantly suppressed when the instrument is subjected to vibration, thus avoiding problems such as blurred readings or pointer breakage caused by violent shaking. 2. The vibration-resistant instrument achieves synergistic enhancement of technical effect through a multi-level protection mechanism: the resistance fluid directly suppresses pointer vibration, the pressurized medium buffers volume changes caused by temperature, the release port responds to sudden pressure anomalies, and the flexible body compensates for long-term wear and tear.

[0005] To achieve the above objectives, this utility model provides a vibration damping instrument, comprising: a body having a display chamber in which a display pointer is movably mounted; a resistance fluid filling the display chamber, the resistance fluid providing resistance to the display pointer to buffer the swing of the display pointer when subjected to vibration; the resistance fluid being transparent; and a pressurized medium filling the display chamber to absorb the pressure after the resistance fluid expands.

[0006] According to the vibration-damping instrument of this utility model, the pressurized medium is air.

[0007] According to the vibration-damping instrument of this utility model, the instrument body is provided with a release port, one end of which extends to the display chamber, and the other end is detachably fitted with a sealing component.

[0009] According to the vibration damping instrument of this utility model, a portion of the sidewall of the display chamber is a flexible body, which is deformed by a compression component to apply pressure to the interior of the display chamber; The extrusion component includes a pressure block that is directed toward the flexible body to extrude it.

[0010] According to the vibration-damping instrument of this utility model, the flexible body is the bottom sidewall of the display chamber.

[0011] According to the vibration damping instrument of this utility model, one end of the release port is connected to the area of ​​the pressurized medium in the display chamber.

[0012] According to the vibration damping instrument of this utility model, the instrument body is provided with a movable groove, and one end of the pressure block is connected to a connecting rod, which extends into the movable groove.

[0013] This invention provides a vibration-damping instrument, comprising: a body having a display chamber and a working chamber, wherein a display pointer is movably mounted in the display chamber; a pressure sensing unit and an elastic metal component are installed in the working chamber, the pressure sensing unit being a wave lamp or a sensing diaphragm, connected to the semi-annular elastic metal component, the elastic metal component being connected to the display pointer via a gear structure. During pressure changes, the pressure is sensed by the wave lamp or sensing diaphragm and transmitted to the semi-annular elastic metal component, causing deformation of the elastic metal component and driving the display pointer to swing through the gear structure.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0020] See Figure 1 , Figure 2 This utility model provides a vibration damping instrument, which includes: The gauge body 1 has a display chamber 12 and a working chamber. A display pointer 11 is movably mounted in the display chamber. A pressure sensing unit and an elastic metal component are installed in the working chamber. The pressure sensing unit can be a wave lamp or a sensing diaphragm, and it is connected to the semi-annular elastic metal component. The elastic metal component is connected to the display pointer 11 via a gear structure. It should be noted that the driving structure of the display pointer 11 in the pressure gauge adopts a currently existing structure, which is unrelated to the innovation of this application and is only briefly described here.

[0021] The pressure gauge senses the pressure change process. The pressure is sensed by the wave lamp or sensing diaphragm and transmitted to the semi-circular elastic metal part. The elastic metal part deforms and drives the display pointer 11 to swing through the gear structure.

[0022] The resistance liquid 2 is filled inside the display chamber 12. The resistance liquid 2 provides resistance to the display pointer 11 to buffer the swing of the display pointer 11 when it is vibrated. The resistance liquid 2 is transparent and preferably a colorless and transparent liquid. Combining the above characteristics, the resistance liquid 2 is selected as a glycerol solution or a silicone oil solution.

[0023] By utilizing the damping effect of the resistance fluid on the display pointer, the swing amplitude of the pointer is significantly suppressed when the instrument is subjected to vibration, avoiding problems such as blurred readings or pointer breakage caused by severe shaking. Simultaneously, the light-transmitting design ensures that the resistance fluid does not obstruct the operator's view of the pointer position through the display chamber, balancing vibration damping function with reading clarity. Compared to traditional rubber pads or spring-buffered structures, this design eliminates the need for frequent replacement of wear parts, and the resistance fluid maintains stable performance, ensuring consistent vibration damping even after long-term use.

[0024] In some embodiments of this application, the display chamber 12 is filled with a pressurized medium 13 to absorb the pressure after the resistance fluid 2 expands. The pressurized medium 13 filling the display chamber 12 further optimizes the adaptability of the instrument. When changes in ambient temperature cause the resistance fluid to expand, the pressurized medium absorbs the excess pressure through compression or expansion, preventing the display chamber from cracking due to excessive internal pressure. In the display chamber 12, the ratio (volume ratio) of the pressurized medium 13 to the resistance fluid 2 is 1:9 or 2:8, etc., that is, the amount of pressurized medium 13 does not need to be too large.

[0025] For example, under high-temperature conditions, the resistance fluid expands due to heat, while the pressurized medium (such as air) is compressed to balance the pressure; in low-temperature environments, the resistance fluid contracts, and the pressurized medium releases pressure to prevent chamber collapse. This dynamic pressure regulation mechanism significantly improves the reliability of the instrument under extreme temperature conditions. In this embodiment, the pressurized medium is air.

[0026] See Figure 2 and Figure 3In some embodiments of this application, the instrument body 1 is provided with a release port 3, one end of which extends into the display chamber 12, and the other end is detachably fitted with a sealing component 4. The release port 3 and the sealing component 4 provided on the instrument body 1 constitute a pressure emergency release system. If the pressure in the display chamber increases suddenly due to abnormal operating conditions (such as the rapid decomposition of the resistance fluid to generate gas), the release port can be opened manually or automatically, and the pressure can be quickly released by removing the sealing component (such as a threaded plug) to prevent the instrument from bursting.

[0027] In some embodiments of this application, a portion of the sidewall of the display chamber 12 is a flexible body 6. The flexible body is deformed by a squeezing component to apply pressure to the interior of the display chamber 12. The flexible body 6 has a certain elasticity and can self-reset after the pressure is lost. The squeezing component includes a pressure block 5, which faces the flexible body to squeeze it. The combination design of the flexible body 6 and the pressure block 5 provides an active pressure adjustment function: by moving the pressure block to squeeze the flexible body (the flexible body is made of rubber or deformable metal, etc.), the pressure inside the chamber can be finely adjusted to compensate for the loss of resistance fluid or leakage of pressurized medium caused by long-term use, thereby extending the service life of the instrument.

[0028] Simultaneously, the pressure block 5 compresses the flexible body 6 to change the pressure inside the display chamber 12, which, in conjunction with the release port 3, optimizes the reading accuracy of the pressure gauge. This is because the pressurized medium 13 does not buffer the swing error of the display pointer 11 caused by vibration. When the display pointer 11 enters the area covered by the pressurized medium 13, in this embodiment, if the pressurized medium 13 is air, the area covered by the pressurized medium 13 is the upper position, and the swing error of the display pointer 11 caused by vibration will increase. In this example, the flexible body is the bottom sidewall of the display chamber.

[0029] At this point (when the display pointer 11 enters the area covered by the pressurized medium 13), for accurate readings, the sealing member 4 can be opened, and the pressure block 5 can be used to compress the flexible body 6, increasing the pressure inside the display chamber 12. Air (pressurized medium 13) is then released through the release port 3. It should be noted that one end of the release port needs to be connected to the area of ​​the pressurized medium within the display chamber.

[0030] After the reading is completed, the pressure block 5 is reset, the flexible body 6 is reset, the pressure in the display chamber 12 is reset, the air flows back to the display chamber 12, and the sealing component 4 is reinstalled.

[0031] In this embodiment, the connecting structure of the pressure block 5 includes a movable groove 51 inside the watch body, and a connecting rod 52 connected to one end of the pressure block, extending into the movable groove. As shown in the figure, the connecting rod 52 extends from the lower end of the watch body 1. When driving, the connecting rod 52 can be held and pushed upwards to facilitate driving the pressure block 5 to move upwards. When resetting, the pressure block 5 will descend due to its own weight.

[0032] The vibration damping instrument achieves synergistic enhancement of technical effectiveness through a multi-layered protection mechanism: the resistance fluid directly suppresses pointer vibration, the pressurized medium buffers volume changes caused by temperature, the release port handles sudden pressure anomalies, and the flexible body compensates for long-term wear and tear. This structure not only solves the problems of easy aging and frequent resonance phenomena in existing vibration damping structures, but also reduces maintenance costs through modular design, making it particularly suitable for pressure monitoring scenarios in high-vibration, wide-temperature-range industrial equipment such as boilers and compressors.

[0033] In summary, this utility model provides a vibration-damping instrument, comprising: a body having a display chamber and a working chamber, wherein a display pointer is movably mounted in the display chamber; a pressure sensing unit and an elastic metal component are installed in the working chamber, the pressure sensing unit being a wave lamp or a sensing diaphragm, connected to the semi-annular elastic metal component, the elastic metal component being connected to the display pointer via a gear structure. During the pressure gauge's sensing of pressure changes, the pressure is sensed by the wave lamp or sensing diaphragm and transmitted to the semi-annular elastic metal component, causing deformation of the elastic metal component and driving the display pointer to swing through the gear structure. A resistance fluid, filling the display chamber, provides resistance to the display pointer, buffering its swing when subjected to vibration; the resistance fluid is transparent and colorless; considering the above characteristics, a glycerol solution or silicone oil solution is selected as the resistance fluid. By utilizing the damping effect of the resistance fluid on the display pointer, the swing amplitude of the display pointer is significantly suppressed when the instrument is subjected to vibration, avoiding problems such as blurred readings or pointer breakage caused by severe shaking. Meanwhile, the translucent design ensures that the resistance fluid will not obstruct the operator's view of the pointer position through the display chamber, balancing vibration damping and reading clarity. Compared to traditional rubber pads or spring buffer structures, this design eliminates the need for frequent replacement of wear parts, and the resistance fluid maintains stable performance, ensuring consistent vibration damping even after long-term use.

[0034] This utility model can: 1. By utilizing the damping effect of the resistance fluid on the display pointer, the swing amplitude of the display pointer is significantly suppressed when the instrument is subjected to vibration, thus avoiding problems such as blurred readings or pointer breakage caused by violent shaking. 2. The vibration-resistant instrument achieves synergistic enhancement of technical effect through a multi-level protection mechanism: the resistance fluid directly suppresses pointer vibration, the pressurized medium buffers volume changes caused by temperature, the release port responds to sudden pressure anomalies, and the flexible body compensates for long-term wear and tear.
