Description

Technical Field

[0001] This invention relates to the field of gas pressure regulating device technology, specifically a gas pressure regulating device with sound insulation and noise reduction functions. Background Technology

[0002] Gas pressure regulators are key equipment in gas transmission and distribution systems, used to stabilize and control gas pressure to ensure safe and stable delivery of gas to users. A gas pressure regulator consists of a measuring element, a transmission element, and a regulating valve. When gas flows out and causes a drop in outlet pressure, the force below the diaphragm exceeds the force of the spring above, causing the diaphragm and valve stem to rise, opening the valve and increasing the gas flow until it stabilizes at the set pressure.

[0003] The main function of a gas regulator is to reduce the high-pressure gas from the pipeline to a stable low pressure suitable for household gas appliances. When the high-pressure gas passes through a narrow valve in the regulator, the flow rate increases sharply, forming turbulence, similar to the principle of whistling, thus producing a high-frequency "hissing" or whistling sound. Furthermore, if the regulator itself or the pipeline connected to it is not installed securely, its natural frequency may coincide with the excitation frequency of the airflow, producing a strong resonance and a loud roaring sound.

[0004] Continuous noise can cause irritability and anxiety, affecting rest and sleep. This is especially true when the regulator is installed on a wall near the bedroom or living area. After long-term use, the seals are prone to aging, wear, or corrosion, thus losing their sealing performance. Leaks can occur in the gap between the upper and lower valve bodies. When the regulator itself is constantly noisy, the slight hissing sound of the leak can be masked and not easily detected, which can easily cause serious safety hazards.

[0005] Therefore, it is essential to design a gas pressure regulating device that offers high sound insulation, noise reduction, and safety. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. The upper and lower positioning blocks are connected by bolts. This not only reduces the connection gap between the lower and upper sound insulation shells by adjusting the bolts, thus enhancing the sound insulation effect, but also facilitates the normal disassembly of the lower and upper sound insulation shells by tightening and loosening the bolts, making subsequent maintenance easier. Furthermore, the elastic deformation of the first spring absorbs vibration energy, significantly reducing the vibration amplitude of the gas pressure regulator. The vibration damping mechanism isolates the gas pressure regulator from the vibration coupling of surrounding pipes and supports, preventing vibration from being transmitted to other components and causing secondary noise, thus significantly reducing the mechanical noise of the gas pressure regulator during operation.

[0017] 2. By installing acoustic sensors around the upper and lower valve bodies, the sound of gas leaks can be quickly and effectively detected. This effectively prevents the sound of leaks from being blocked by the soundproof cover, thus preventing nearby personnel from hearing the gas leak immediately and avoiding safety hazards. Simultaneously, the leaking gas flows counter-clockwise through the guide plate, causing the acoustic sensors to slide counter-clockwise. As they slide, they gradually approach the leak point and monitor the sound of the leaking gas in real time. When close to the leak point, the sensors can capture stronger and purer sound pressure signals, improving the sensitivity and accuracy of monitoring. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-8 The present invention provides a technical solution: a gas pressure regulating device with sound insulation and noise reduction function, including a base 2, a lower sound insulation shell 3 fixedly connected to the upper side of the base 2, an alarm 1 provided on one side of the lower sound insulation shell 3 and the alarm 1 fixedly connected to the base 2, an upper sound insulation shell 5 provided on the upper side of the lower sound insulation shell 3, a locking mechanism 4 provided on the outer side of the lower sound insulation shell 3 and the upper sound insulation shell 5, and four sets of damping mechanisms 7 provided on the inner side of the locking mechanism 4 to prevent the gas regulator from vibrating and emitting sound. The gas regulator includes an upper valve mechanism 6 and a lower valve mechanism 9. A gas leakage monitoring mechanism 8 for real-time monitoring of gas leakage is provided on one side of the damping mechanism 7, and the upper valve mechanism 6 and the lower valve mechanism 9 are located inside the gas leakage monitoring mechanism 8.

[0036] The following is a supplementary explanation based on the above structure: both the lower soundproof shell 3 and the upper soundproof shell 5 are made of special soundproof materials. The locking mechanism 4 is used to clamp the lower soundproof shell 3 and the upper soundproof shell 5, thereby reducing the connection gap between the lower soundproof shell 3 and the upper soundproof shell 5, so that the soundproof effect of the lower soundproof shell 3 and the upper soundproof shell 5 is better.

[0037] The locking mechanism 4 includes an upper positioning ring 44 fixedly connected to the outside of the upper soundproof shell 5, a lower positioning ring 45 fixedly connected to the outside of the lower soundproof shell 3, an upper positioning block 41 fixedly connected to the outside of the upper positioning ring 44, a lower positioning block 42 fixedly connected to the outside of the lower positioning ring 45, the upper positioning block 41 and the lower positioning block 42 being bolted together, and two connecting blocks 43 fixedly connected to the outside of the lower soundproof shell 3.

[0038] The following is a supplementary explanation based on the above structure: the upper positioning block 41 and the lower positioning block 42 are connected by bolts. This not only reduces the connection gap between the lower sound insulation shell 3 and the upper sound insulation shell 5 by adjusting the bolts, thus enhancing the sound insulation effect, but also facilitates the normal disassembly of the lower sound insulation shell 3 and the upper sound insulation shell 5 by tightening or loosening the bolts, making it convenient for subsequent maintenance.

[0039] The shock absorption mechanism 7 includes a lower fixed plate 73 fixedly connected to one side of the upper positioning ring 44 and the lower positioning ring 45. Four connecting rods 72 are hinged to the upper side of the lower fixed plate 73. The other end of each connecting rod 72 is hinged to the upper fixed plate 71. A support plate 78 is hinged to the upper side of the lower fixed plate 73. A positioning post 77 is fixedly connected to the upper side of the support plate 78. A telescopic rod 75 is slidably connected inside the positioning post 77. A connecting plate 74 is fixedly connected to the other end of the telescopic rod 75. The connecting plate 74 is hinged to the upper fixed plate 71. A first spring 76 is provided on the outside of the positioning post 77. One end of the first spring 76 is fixedly connected to the connecting plate 74 and the other end of the first spring 76 is fixedly connected to the support plate 78.

[0040] The following is a supplementary explanation based on the above structure: During the throttling process of the medium in the valve, it will be subject to friction, resistance and disturbance, forming vortices. When the frequency of vortex shedding is close to or consistent with the structural frequency of the regulator and its auxiliary devices, resonance will occur, causing the entire gas regulator to vibrate. Vibration may not only cause the seals to loosen or be damaged, leading to leakage, but also be accompanied by noise, affecting the surrounding environment and the health of the operators.

[0041] When the gas regulator is subjected to vibration or impact, the first spring 76 in the damping mechanism 7 will undergo elastic deformation to absorb and store vibration or impact energy. This elastic deformation can effectively slow down the transmission of vibration or impact and reduce its impact on the gas regulator.

[0042] The shock absorption mechanism 7 converts vibration and impact energy into the elastic energy of the first spring 76 and stores it. When the external force disappears, the first spring 76 will gradually release the stored energy, so that the gas regulator returns to its original state, thereby reducing the impact of vibration and impact.

[0043] The vibration damping mechanism 7 effectively reduces the vibration of the gas pressure regulator, reducing noise generation at the source. It absorbs vibration energy through the elastic deformation of the first spring 76, greatly reducing the vibration amplitude of the pressure regulator. At the same time, the vibration damping mechanism 7 isolates the gas pressure regulator from the vibration coupling of surrounding pipes and supports, preventing vibration from being transmitted to other components and causing secondary noise, thus significantly reducing the mechanical noise of the pressure regulator during operation.

[0044] The air leakage detection mechanism 8 includes a sealing ring 82 fixedly connected to one side of the upper fixed plate 71. Two sealing rings 81 are fixedly connected to the inner side of the sealing ring 82. A T-shaped groove 86 is provided inside the sealing ring 82. A T-shaped slider 85 is slidably connected inside the T-shaped groove 86. An acoustic sensor 84 is fixedly connected to one side of the T-shaped slider 85. An airflow groove is provided on one side of the T-shaped groove 86. Several air guide plates 83 are evenly fixedly connected inside the airflow groove. The air guide plates 83 are all installed at an angle.

[0045] The following is a supplementary explanation based on the above structure: the T-shaped slider 85 is used to drive the acoustic sensor 84 to slide along the T-shaped groove 86. The T-shaped groove 86 is circular and surrounds the outer side of the upper valve body 63 and the lower valve body 98. The airflow groove is used to store the gas that leaks out between the upper valve body 63 and the lower valve body 98 for the first time. The two sealing rings 81 are used to prevent the gas inside the airflow groove from leaking out again and entering the interior of the lower soundproof shell 3 and the upper soundproof shell 5.

[0046] The acoustic sensor 84 can be a sound pressure sensor. When a gas leak occurs, the gas flow parameters at the leak point change, and the resulting leak sound wave signal is transmitted to the sound pressure sensor along with the background noise under normal operating conditions. By extracting the feature value of the sound wave signal, the feature value when no leak occurs is used as a threshold and compared with the feature value obtained when the pipeline is running to determine the leak.

[0047] In a quiet environment, a slight gas leak will produce a very faint hissing sound. This is an important auditory clue for users or maintenance personnel to detect leaks early. If the regulator is soundproofed (such as by installing a soundproof cover), the cover will block the hissing sound from the leak point from spreading outwards, thus rendering the method of identifying leaks by sound ineffective.

[0048] Therefore, when a leak occurs at a connection between the upper valve body 63 and the lower valve body 98, gas leaks. The leaking gas flows counterclockwise in the same direction, guided by the gas guide plate 83. Since the friction between the T-shaped slider 85 and the T-shaped groove 86 is less than the thrust of the leaking gas, the acoustic sensor 84 is driven to slide counterclockwise. During the sliding process, it gradually approaches the leak point and monitors the sound of the leaking gas in real time. The closer to the leak point, the more accurate the sound pressure sensor monitoring is usually. This is because the sound pressure intensity decreases with increasing distance. When it is close to the leak point, the sensor can capture a stronger and purer sound pressure signal, which helps to improve the sensitivity and accuracy of monitoring. When a strong sound wave signal is detected, the feature value of the sound wave signal is extracted. The feature value when no leak occurs is used as a threshold and compared with the feature value obtained when the pipeline is running to determine the leak. When the acoustic sensor 84 determines that a gas leak has occurred, it will send a signal to the alarm 1. At this time, the alarm 1 will sound an alarm to remind the surrounding personnel that a gas leak has occurred and that the main gas valve should be closed in time.

[0049] The upper valve mechanism 6 includes an upper valve body 63 fixedly connected to the inner side of the sealing ring 82, and the lower valve mechanism 9 includes a lower valve body 98 fixedly connected to the inner side of the sealing ring 82. The upper valve body 63 and the lower valve body 98 are bolted together. The upper valve body 63 has an upper air chamber inside, and the lower valve body 98 has a lower air chamber inside. A diaphragm 64 is fixedly connected between the upper valve body 63 and the lower valve body 98.

[0050] The upper valve body 63 has a threaded groove 631 on its upper side. A sealing cover 62 is threadedly connected inside the threaded groove 631. A flat plate 621 is provided on the lower side of the sealing cover 62 and is threadedly connected to the threaded groove 631. A second spring 65 is fixedly connected to the lower side of the flat plate 621. A pressure plate 68 is fixedly connected to the lower end of the second spring 65. An upper cover plate 66 is provided inside the second spring 65. A connecting shaft is fixedly connected to the lower side of the upper cover plate 66. The other end of the connecting shaft passes through the pressure plate 68 and the diaphragm 64 and is fixedly connected to the lower cover plate 69. The diaphragm 64 is located between the lower cover plate 69 and the pressure plate 68. The diaphragm 64 is fixedly connected to the outer side of the connecting shaft and fits tightly. A third spring 67 is provided on the outer side of the connecting shaft. One end of the third spring 67 is fixedly connected to the upper cover plate 66 and the other end is fixedly connected to the pressure plate 68.

[0051] An exhaust pipe 61 is fixedly connected to the upper side of the upper valve body 63. A filter disc 611 is fixedly connected inside the exhaust pipe 61. An exhaust hole 612 is provided on the lower side of the exhaust pipe 61 and the exhaust hole 612 is connected to the upper air chamber.

[0052] The lower valve body 98 has an air inlet groove 93 and an air outlet groove 97 on its lower sides. The air inlet groove 93 is connected to one of the connecting blocks 43, and the air outlet groove 97 is connected to the other connecting block 43. One end of the air inlet groove 93 is connected to an air inlet hole 92, and the other end of the air inlet hole 92 is connected to the lower air chamber. The air outlet groove 97 is connected to the lower air chamber. A pressure column 91 is provided on the upper side of the air inlet hole 92. A rotating plate 96 is fixedly connected to the upper side of the pressure column 91. The other end of the rotating plate 96 is fixedly connected to a connecting shaft. Side plates 94 are fixedly connected to both sides of the rotating plate 96. A fixing block 95 is provided in the middle of the two side plates 94. The fixing block 95 is fixedly connected to the lower air chamber and is hinged to the side plates 94.

[0053] The following is a supplementary explanation based on the above structure: the gas passes through the connecting block 43 and the pipeline to the inlet slot 93, and then enters the interior of the inlet hole 92 through the inlet slot 93. When the gas consumption after the outlet increases or the inlet pressure decreases, the outlet pressure decreases. The pressure makes the force acting on the lower side of the diaphragm 64 less than the force of the spring on the diaphragm 64, causing the diaphragm 64 to descend, driving the connecting shaft to descend, and driving the rotating plate 96 to rotate, causing the pressure column 91 to rise, increasing the gas flow rate, and restoring the outlet pressure to the set value. Conversely, when the gas consumption after the outlet decreases or the inlet pressure increases, the pressure column 91 descends, the flow rate decreases, and the outlet pressure can still be restored. The outlet pressure value can be given by adjusting the spring force, thereby stably converting the high-pressure gas into low-pressure gas suitable for user use, ensuring that the gas pressure is stably and safely delivered to the user end.

[0054] The upper positioning block 41 and the lower positioning block 42 are connected by bolts. This not only reduces the connection gap between the lower sound insulation shell 3 and the upper sound insulation shell 5 by adjusting the bolts, thus enhancing the sound insulation effect, but also facilitates the normal disassembly of the lower sound insulation shell 3 and the upper sound insulation shell 5 by tightening and loosening the bolts, making subsequent maintenance easier. Furthermore, the elastic deformation of the first spring 76 absorbs vibration energy, significantly reducing the vibration amplitude of the gas pressure regulator. The vibration damping mechanism 7 isolates the gas pressure regulator from the vibration coupling of surrounding pipes and supports, preventing vibration from being transmitted to other components and causing secondary noise, thus significantly reducing the mechanical noise of the gas pressure regulator during operation.

[0055] By installing acoustic sensors 84 around the upper valve body 63 and the lower valve body 98, the sound of gas leakage can be quickly and effectively detected. This effectively prevents the sound of leakage from the leak point from being blocked by the soundproof cover and unable to propagate outward, thus preventing people in the vicinity from hearing the sound of gas leakage in time and causing safety hazards. At the same time as monitoring, the leaking gas is guided by the gas guide plate 83 and flows counterclockwise, thereby driving the acoustic sensor 84 to slide counterclockwise. During the sliding process, it gradually approaches the leak point and monitors the sound of the leaking gas in real time. When it gets close to the leak point, the sensor can capture a stronger and purer sound pressure signal, which helps to improve the sensitivity and accuracy of monitoring.
