Description

Technical Field

[0001] This invention belongs to the field of airtightness testing technology, and more specifically, relates to an airtightness testing device for a gas pressure regulator. Background Technology

[0002] In modern gas transmission and distribution systems, gas pressure regulators are key components that play a decisive role in ensuring the stable and safe transmission of gas. If the gas pressure regulator is not airtight and gas leakage occurs, it can easily lead to serious safety accidents such as fires and explosions, which not only threaten the safety of people's lives and property, but may also cause large-scale gas outages. Therefore, conducting strict and efficient airtightness testing on gas pressure regulators is a crucial link in ensuring the safe operation of gas transmission and distribution systems and is of paramount importance in the gas industry.

[0003] However, the current gas pressure regulator air tightness test mostly relies on manual operation. It requires manual connection of equipment, inflation, and observation of bubbles by applying leak detection liquid to determine the leak. The operation is cumbersome and the detection speed is slow, making it difficult to adapt to large-scale production. The test results are greatly affected by human factors and are prone to missed or false detections due to uneven application of leak detection liquid or differences in observation.

[0004] In view of this, the present invention is proposed. Summary of the Invention

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] like Figures 1 to 8 As shown, a gas pressure regulator air tightness testing device includes a first support 1, a second support 2, and a sorting mechanism disposed above the first support 1 and the second support 2. Two rollers 3 are rotatably mounted on the first support 1 and the second support 2, and a conveyor belt 4 is mounted on the rollers 3. The sorting mechanism includes two sets of clamping assemblies for auxiliary fixing. A turntable 18 is mounted on the two sets of clamping assemblies. A telescopic shaft 22 and two electric telescopic rods 20 are mounted on the turntable 18. A connecting shaft 21 is slidably mounted on the telescopic shaft 22. A top plate 24 is mounted at the end of the two electric telescopic rods 20. A first bevel gear 32 is mounted on the connecting shaft 21. A second bevel gear 33 meshes with the first bevel gear 32. A drive shaft 34 is mounted in the second bevel gear 33. A connecting plate 35 is connected to the bottom of the top plate 24. The drive shaft 34 is rotatably mounted in the connecting plate 35. A second driven shaft 37 is connected to one end of the roller 3 on the second bracket 2. A second belt 36 is mounted on the second driven shaft 37 and the drive shaft 34. In this setup, the first support 1 and the second support 2 serve as the basic support structure of the device, bearing the transmission system and sorting mechanism to ensure overall stability. The roller 3 drives the conveyor belt 4 to rotate, realizing the horizontal transport of the placement blocks 5 and the pressure regulator. The placement blocks 5 are installed on the surface of the conveyor belt 4, carrying the pressure regulator and transporting it to the inspection station at a fixed pace. The sorting mechanism includes a turntable 18, clamping components, etc. The turntable 18 is equipped with two sets of clamping components, which can switch between the inspection and sorting stations by rotating 180° to realize the transfer of qualified and unqualified products. The clamping components help fix the pressure regulator and complete the clamping and releasing actions in conjunction with the inspection process. The telescopic shaft 22 can slide within the connecting shaft 21 to adapt to the spacing changes when the turntable 18 presses down, ensuring the clamping... The clamping assembly is aligned with the pressure regulator; the electric telescopic rod 20 drives the top plate 24 to move up and down, realizing the downward pressing and upward resetting of the clamping assembly. The first bevel gear 32, the second bevel gear 33, the transmission shaft 34, the second belt 36, and the second driven shaft 37 together form a transmission chain. The first motor 25 drives the connecting shaft 21 to rotate. Through the meshing transmission of the first bevel gear 32 and the second bevel gear 33, the transmission shaft 34 and the second belt 36 drive the roller 3 of the second support 2 to rotate, so that the conveyor belt 4 on the second support 2 drives the placement block 5 installed on it to move exactly one station, ensuring that the previous unqualified pressure regulator moves forward one station, so that the empty station behind reaches the required position, realizing the sorting and transfer of unqualified products.

[0021] like Figures 1 to 8As shown, in a specific embodiment, the clamping assembly includes a first housing 9 and a second housing 10. A cylinder 11 is installed between the first housing 9 and the second housing 10. A connecting block 12 is connected to the end of the cylinder 11. A rotating shaft 13 is installed on the connecting block 12. Two rotating rods 14 are rotatably installed on the rotating shaft 13. A clamping arm 15 is hinged to the end of each of the two rotating rods 14. A rotating shaft 16 rotates in the clamping arm 15. The rotating shaft 16 is connected to the first housing 9. A caliper 17 is installed at the end of the clamping arm 15. In this configuration, the first outer shell 9 and the second outer shell 10 serve as the support frame for the clamping assembly. The first outer shell 9 and the second outer shell 10 are connected by bolts. The detachable design facilitates the maintenance and repair of the cylinder 11. When installed together, they ensure the stability of the internal component movement and also provide protection. The cylinder 11 and the rotating shaft 16 are fixed, providing a mechanical connection basis. The cylinder 11 serves as a power source, pushing the connecting block 12 through the extension and retraction of the piston rod, driving the clamping action. When extended, it pushes the clamping arm 15 to clamp the pressure regulator, and when retracted, it releases. The connecting block 12 transmits the power of the cylinder 11 to the rotating rod 14. The rotating shaft 13 serves as the hinge fulcrum of the rotating rod 14. The rotating rod 14 amplifies the cylinder thrust through the lever principle, causing the clamping arm 15 to swing. The clamping arm 15 rotates around the rotating shaft 16, and the end clamp 17 clamps the outer wall of the pressure regulator. The rotating shaft 16 fixes the rotation fulcrum of the clamping arm 15. The clamp 17 directly contacts the pressure regulator, achieving high-strength clamping through the lever structure, ensuring reliable sealing during testing.

[0022] like Figures 1 to 8 As shown, the turntable 18 is further provided with a guide groove 19, and rollers 23 are rotatably mounted at the ends of the two electric telescopic rods 20. The rollers 23 slide in engagement with the guide groove 19, and the guide groove 19 is arc-shaped to ensure that the turntable 18 can rotate. In this configuration, the arc-shaped guide groove 19 guides the rollers 23 at the ends of the electric telescopic rods 20 to slide, so that the clamping assembly swings synchronously with the rotation of the turntable 18, ensuring accurate transfer path. The sliding engagement of the rollers 23 with the guide groove 19 enables precise transfer of the pressure regulator.

[0023] like Figures 1 to 8 As shown, a second motor 29 is mounted on the first support 1, and an output shaft 28 is mounted on the second motor 29. A first driven shaft 26 is mounted on one end of the roller 3 on the first support 1, and a first belt 27 is mounted on the first driven shaft 26 and the output shaft 28. In this configuration, the second motor 29 serves as the power source for the first support 1, driving the first belt 27 through the output shaft 28. The first belt 27 connects the output shaft 28 and the first driven shaft 26, transmitting power to the roller 3 and driving the conveyor belt 4 to transport the pressure regulator.

[0024] like Figures 1 to 8As shown, further, several equidistant placement blocks 5 are installed on the conveyor belt 4. Each placement block 5 is connected to the conveyor belt 4 by two sets of bolts 7 and nuts 8, which are arranged in a straight line. The placement block 5 is provided with a first slot 38 and a second slot 39. A gas pressure regulator 6 is placed on the placement block 5 on the first support 1. The first slot 38 is used to block the gas outlet of the gas pressure regulator 6, and the inner walls of the first slot 38 and the second slot 39 are provided with elastic buffer pads. In this setup, the placement block 5 is fixed to the conveyor belt 4 by bolts 7 and nuts 8, supporting the gas pressure regulator 6. Bolts 7 and nuts 8 ensure a firm connection between the placement block 5 and the conveyor belt 4, arranged in a straight line for even force distribution, and guarantee the normal operation of the conveyor belt 4. The placement block 5 can be disassembled by removing bolts 7 and nuts 8. By replacing different placement blocks 5, the device can be adapted to different gas pressure regulators 6. The protrusion in the first slot 38 of the placement block 5 matches the shape of the gas outlet of the gas pressure regulator 6, and works with the elastic buffer pad to achieve a seal through contact. The second slot 39 matches the shape of the gas pressure regulator 6, and works with the elastic buffer pad on its inner wall to flexibly position the gas pressure regulator 6, ensuring the stability of the gas pressure regulator 6 during movement.

[0025] like Figures 1 to 8 As shown, a first motor 25 is mounted on the top plate 24, and a connecting shaft 21 passes through the top plate 24 and is mounted on the first motor 25. A column 30 is connected to the top plate 24, and a controller 31 is mounted on the top plate 24. In this configuration, the first motor 25 drives the connecting shaft 21 to rotate, which in turn drives the conveyor belt 4 of the second support 2 to rotate through bevel gear transmission. At the same time, it controls the rotation of the turntable 18. The connecting shaft 21 transmits the power of the first motor to the first bevel gear 32. The column 30 supports the top plate 24 to ensure structural stability. The controller 31, as the core of the system, precisely controls the timing of the actions of each component through a preset program.

[0026] like Figures 1 to 8 As shown, furthermore, a pressure sensor 40 for detecting the airtightness data of the gas regulator 6 is installed at the bottom of the second housing 10. An air inlet pipe is provided in the second housing 10, connected to an external gas source, and a solenoid valve is installed on the air inlet pipe. In this configuration, the pressure sensor 40 detects the internal pressure change of the gas regulator 6 in real time, acquires airtightness data, and feeds it back to the controller 31, causing the controller 31 to issue commands for subsequent actions. The air inlet pipe is connected to an external gas source, introducing detection gas into the gas regulator 6. The solenoid valve, controlled by the controller 31, opens or closes the air inlet passage, realizing automated control of the filling process.

[0027] like Figures 1 to 8As shown, the first support 1 and the second support 2 are arranged parallel to each other and spaced apart, with two sets of clamping components located above the first support 1 and the second support 2 respectively. In this configuration, the first support 1 and the second support 2 are arranged parallel to each other to support the transmission system and the sorting mechanism, ensuring overall stability. The two sets of clamping components are located on the first support 1 and the second support 2 respectively. One set of clamping components is used to clamp the gas pressure regulator 6 to be tested, while the other set of clamping components is used to transfer the unqualified gas pressure regulator 6. This allows the testing of the gas pressure regulator 6 to be tested and the placement and transfer of the unqualified gas pressure regulator 6 to be carried out simultaneously, improving testing efficiency.

[0028] like Figures 1 to 8 As shown, furthermore, the spacing of the placement blocks 5 on the conveyor belt 4 is matched with the detection cycle of the gas pressure regulator 6. When the turntable 18 rotates 180°, the conveyor belt 4 on the second support 2 moves exactly one station. In this setup, the spacing of the placement blocks 5 on the conveyor belt 4 matches the detection cycle, ensuring that the gas pressure regulator 6 arrives at the detection station at a fixed rhythm. When the turntable 18 rotates 180°, the conveyor belt 4 on the second support 2 causes the placement blocks 5 installed on it to move exactly one station, ensuring that the previous unqualified gas pressure regulator 6 moves forward one station, allowing the empty station behind to reach the required position, realizing the sorting and transfer of unqualified products, and ensuring that the detection and sorting actions can be accurately synchronized.

[0029] like Figures 1 to 8 As shown, the solenoid valve and pressure sensor 40 are both electrically connected to the controller 31, the electric telescopic rod 20 is electrically connected to the controller 31, and the first motor 25 and the second motor 29 are electrically connected to the controller 31. In this configuration, the solenoid valve, pressure sensor 40, electric telescopic rod 20, first motor 25, and second motor 29 are all electrically connected to the controller 31, achieving automated control through circuit signal transmission and ensuring that each component works collaboratively according to preset logic.

[0030] The implementation principle of a gas pressure regulator airtightness detection device in this embodiment is as follows: The second motor 29 drives the roller 3 on the first bracket 1 to rotate through the first belt 27, so that the conveyor belt 4 drives the placement blocks 5 with equidistant distribution on the surface to transport the gas pressure regulator 6. The protrusion in the first card slot 38 of the placement block 5 is adapted to the shape of the outlet of the pressure regulator, and the elastic buffer pad is used to achieve sealing and plugging through abutment. The elastic buffer pad on the inner wall of the second card slot 39 flexibly positions the gas pressure regulator 6. The station spacing of the conveyor belt 4 is synchronized with the detection rhythm to ensure that the gas pressure regulator 6 is accurately positioned at the detection station with the placement block 5. When the gas pressure regulator 6 reaches the detection area, the electric telescopic rod 20 acts first, pushing the turntable 18 downward. The telescopic shaft 22 slides in the connecting shaft 21 to adapt to the change in the distance between components, so that the air inlet sealing ring at the bottom of the second housing 10 is accurately aligned with the air inlet of the gas pressure regulator 6. Subsequently, the cylinder 11 is started, and the connecting block 12 is used to drive the rotating shaft 13 and the rotating rod 14 to swing, driving the clamping arm 15 to rotate around the rotating shaft 16, so that the caliper 17 uses the lever principle to clamp the outer wall of the gas pressure regulator 6 to form a stable sealing structure. At this time, the solenoid valve on the air inlet pipe is opened under the instruction of the controller 31, and a constant pressure gas is introduced into the gas pressure regulator 6. The pressure sensor 40 collects the pressure data in real time and feeds it back to the controller 31 for analysis and determination. If the pressure drop is within the allowable range, it is judged as qualified. The cylinder 11 releases the clamping arm 15, and the electric telescopic rod 20 drives the turntable 18 to move up and reset. The second motor 29 drives the conveyor belt 4 to convey the qualified gas pressure regulator 6 backward, and the next gas pressure regulator 6 to be inspected enters the station with the placement block 5; if the pressure drop exceeds the threshold value, it is judged as unqualified. The cylinder 11 maintains the clamping state. After the electric telescopic rod 20 moves up, the first motor 25 drives the connecting shaft 21 to rotate. Through the meshing transmission of the first bevel gear 32 and the second bevel gear 33, the roller 3 on the second bracket 2 is driven to operate through the transmission shaft 34 and the second belt 36, so that the conveyor belt 4 on the second bracket 2 drives the placement block 5 installed thereon to just move one station, ensuring that the previous unqualified gas pressure regulator 6 moves forward one station, so that the empty station behind reaches the required position, realizing the sorting and transfer of unqualified products. At the same time, the turntable 18 rotates 180°. The roller 23 at the end of the electric telescopic rod 20 slides along the guide groove 19, and the unqualified gas pressure regulator 6 is transferred to the placement block 5 on the second bracket 2. Another set of clamping components is synchronously aligned with the new gas pressure regulator 6 to be inspected, and enters the next round of detection process. The controller 31, as the core of the system, precisely controls the action timing of each component through a preset program, realizing the full-process automation of the airtightness detection of the gas pressure regulator 6. The qualified products continue to flow into the subsequent processes through the conveyor belt 4 on the first bracket 1, and the unqualified products are transferred to the sorting area through the conveyor belt 4 on the second bracket 2, effectively improving the detection efficiency and accuracy, reducing the labor cost, and ensuring the continuity and reliability of the production line at the same time.
