[0002] During the production and processing of gas pressure regulating stations, airtightness testing is a crucial step to ensure the safety and normal operation of the equipment. Gas pressure regulating stations are mainly used to regulate high-pressure natural gas to an appropriate low pressure for supply to users. Since natural gas is a flammable and explosive gas, any gas leakage may lead to serious safety hazards and even cause fire or explosion accidents;

[0003] The purpose of airtightness testing is to detect the sealing performance of the pressure regulating equipment and ensure that there are no leaks in its various connecting parts, pipelines, valves, pressure regulators and other components. By applying a certain pressure of gas and detecting whether the equipment maintains the pressure, potential leakage points can be found, and thus repair measures can be taken. Generally, gas or airtightness testing instruments are used during the testing process to ensure that the equipment of the pressure regulating station meets the safety standards before being put into use, avoid leakage during operation, and ensure the safety, stability and reliability of the gas supply system;

[0004] Therefore, airtightness testing is an indispensable part of the production and processing of gas pressure regulating stations to ensure that no safety accidents occur when they are put into actual use.

The cylinder is started to make the first sealing gasket descend to contact the opening of the upper pipeline for sealing.

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Example 1, as Figure 1 and Figure 2 shown, a gas pressure regulating station production and processing airtightness testing device includes a base 1. Triangular plates 2 are fixedly connected to both the left end and the right end of the base 1. Observation components 3 are rotatably installed together at the upper parts of the mutually approaching ends of the two triangular plates 2. By providing the observation components 3, the gas pressure regulating station can be detected in a closed manner, and during the detection process, the air leakage position can be visually observed;

[0034] A dust feeding component 5 is fixedly installed on the outer surface of the observation component 3. By providing the dust feeding component 5, dust can be conveyed into the gas pressure regulating station. After the dust enters the inner cavity of the gas pressure regulating station, the pressurizing device inside the observation component 3 can pressurize the inside of the gas pressure regulating station, so that the dust can be ejected from the air leakage position of the gas pressure regulating station and then adhere to the inner surface of the observation component 3. Then, by observing the position where the dust is ejected, the specific air leakage position of the gas pressure regulating station can be judged. Moreover, the dust feeding component 5 can also keep the air pressure consistent when conveying dust into the gas pressure regulating station, and during the use process, the dust can always be kept in a lifted state, so as to facilitate subsequent airtightness detection of the gas pressure regulating station.

[0035] Example 2, on the basis of Example 1, for the purpose of realizing the airtightness test of the gas pressure regulating station.

[0036] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、Figure 4 , Figure 5 and Figure 6 , the observation component 3 includes a first convex plate 31 and a second convex plate 32. At one end where the first convex plate 31 and the second convex plate 32 are close to each other, a first installation groove 33 is provided. At the inner surface of the two first installation grooves 33 near the outer edge, a first transparent observation plate 34 is fixedly connected. At the upper ends of the first convex plate 31 and the second convex plate 32 where they are far from each other, a second installation groove 35 is provided. At the inner surface of the two second installation grooves 35, a second transparent observation plate 36 is fixedly connected. At one end where the two second transparent observation plates 36 are close to each other, a third transparent observation plate 37 is fixedly connected. At the left and right ends of the first convex plate 31 and the second convex plate 32, an installation component 38 is fixedly installed. At the upper end of the third transparent observation plate 37 on the front side, a magnetic attraction block 7 is slidably connected.

[0037] Furthermore, the installation component 38 includes a connecting pipe 381 fixedly connected to the common left ends of the first convex plate 31 and the second convex plate 32. The connecting pipe 381 penetrates through the left ends of the first convex plate 31 and the second convex plate 32 and extends into the interior of the first transparent observation plate 34. At the inner surface of the connecting pipe 381, an inner sleeve 382 is fixedly connected. At the edge of the inner surface of the inner sleeve 382 located on the outer side, a curved pipe 383 is fixedly connected. At the left upper edge of the second convex plate 32, a fixed seat 384 is fixedly connected. At the upper end of the fixed seat 384, a spiral booster pump 385 is fixedly connected. The output end of the spiral booster pump 385 is fixedly connected to one end of the curved pipe 383. At the right upper edge of the second convex plate 32, a dust delivery component 5 is fixedly installed.

[0038] Furthermore, two symmetrically distributed support rods 39 are slidably connected to the lower ends of the first convex plate 31 and the second convex plate 32. The lower ends of the two support rods 39 on the same side are in mutual contact with the upper end of the base 1.

[0039] Furthermore, a hollow pipe 61 is fixedly connected to the lower end of the second convex plate 32 on the side close to the first convex plate 31. A rotating rod 62 is rotatably connected to the inner surface of the hollow pipe 61. At the left and right ends of the rotating rod 62, limiting disks 63 are fixedly connected. The outer sides of one ends where the two limiting disks 63 are close to each other are fixedly connected to the left and right ends of the first convex plate 31 respectively. The outer sides of one ends where the two limiting disks 63 are far from each other are respectively rotatably connected to the triangular plates 2 on the same side.

[0040] First, place the gas pressure regulating station into the first installation groove 33 opened on the inner surface of the second convex plate 32. Then, connect the two ends of the gas pressure regulating station to the connecting pipes 381 on both sides respectively. Subsequently, fit the first convex plate 31 and the second convex plate 32 together. During the process of fitting the first convex plate 31 and the second convex plate 32, the first convex plate 31 drives the rotating rod 62 fixedly connected to it to rotate on the inner surface of the hollow tube 61 and rotates around the center point of the limiting disc 63. At the same time, the rotating rod 62 drives the two limiting discs 63 to rotate on the surface of the triangular plate 2 on the same side until the first convex plate 31 and the second convex plate 32 are fitted together;

[0041] After fitting, the support rods 39 can be slid into the lower ends of the first convex plate 31 and the second convex plate 32 in sequence to support the first convex plate 31 and the second convex plate 32;

[0042] When fitting the first convex plate 31 and the second convex plate 32 as described above, the buckle in the prior art can be added to make the fitting of the first convex plate 31 and the second convex plate 32 more stable. The buckle is a conventional design in the prior art. In this solution, it only needs to satisfy the clamping of the first convex plate 31 and the second convex plate 32. Its specific shape and installation position are both conventional designs in the prior art;

[0043] After the first convex plate 31 and the second convex plate 32 are fitted, at this time, the ash feeding assembly 5 can be controlled to make the dust stored inside the ash feeding assembly 5 enter the gas pressure regulating station. Then, start the spiral booster pump 385, so that the spiral booster pump 385 continuously applies air pressure to the inside of the gas pressure regulating station through the curved pipe 383 fixedly connected to its output end. If there is a leakage position in the gas pressure regulating station, the dust will be ejected from the leakage point and then sprayed on the surface of the first transparent observation plate 34, the second transparent observation plate 36 or the third transparent observation plate 37. Subsequently, the personnel can observe the surfaces of the first transparent observation plate 34, the second transparent observation plate 36 and the third transparent observation plate 37 to intuitively judge the position of the dust, thereby obtaining the leakage position of the gas pressure regulating station.

[0044] The above-mentioned spiral booster pump 385 is a conventional setting in the prior art. In this solution, it only needs to satisfy the pressurization of the inside of the gas pressure regulating station. Its specific working principle is as follows:

[0045] Power transmission: The spiral booster pump 385 is usually tightly connected to the crankshaft pulley of the engine through a belt. When the engine runs, the crankshaft rotates, drives the spiral blade shaft of the supercharger through the belt, thereby providing power for the supercharger and making the spiral blades start to rotate;

[0046] Air intake: When the spiral blades rotate, a negative pressure area is formed at the air inlet of the supercharger. Due to the pressure difference, the outside air is inhaled into the supercharger. The air enters along the axial direction of the spiral blades. During this process, the air flow rate is relatively low, and the air can enter the supercharger more smoothly.

[0047] Air compression: The air entering the supercharger is pushed by the spiral blades and moves along the spiral trajectory towards the air outlet. During this process, the space between the spiral blades gradually becomes smaller, squeezing the air. The air is gradually compressed, and its pressure and density continuously increase. In the double - spiral - structure supercharger, the two spiral blades mesh with each other. During rotation, the gap between them also gradually becomes smaller, further compressing the air.

[0048] Air output: The compressed air with increased pressure and density is discharged from the air outlet of the supercharger.

[0049] Therefore, the specific installation method and circuit connection method of the spiral supercharger 385 are both conventional designs in the prior art, so they will not be elaborated in detail in this solution.

[0050] Embodiment 3: On the basis of Embodiment 2, this embodiment aims to achieve the purpose of scraping off the ejected dust and how to send the dust into the gas pressure regulating station for airtightness detection.

[0051] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , a dust - scraping ring 391 is slidably connected to the inner surface of the cavity jointly formed by the two transparent observation plates 34. A number of circular grooves 392 are annularly arranged on the inner surface of the dust - scraping ring 391, and ball bearings 393 are rotatably connected to the inner surfaces of the number of circular grooves 392.

[0052] Further, the ash delivery assembly 5 includes an ash storage box 51 fixedly connected to the upper right edge of the second convex plate 32. Limiting holes 52 are provided on the upper left and upper right sides of the outer surface of the ash storage box 51. L-shaped tubes 53 are fixedly connected to the inner surfaces of the two limiting holes 52. A filtering assembly 54 is fixedly installed at the common end of the two L-shaped tubes 53 close to each other. An installation hole 56 is provided on the front side of the right part of the outer surface of the ash storage box 51. A feeding pipe 57 is fixedly installed on the inner surface of the installation hole 56. A push plate 58 is slidably connected to the inner surface of the ash storage box 51. The middle part of the left end of the push plate 58 is fixedly connected to a push rod 59. The left side of the outer surface of the push rod 59 penetrates through the left end of the ash storage box 51 and extends to the outside. A rectangular plate 50 is fixedly connected to the left end of the push rod 59. The right end of the ash storage box 51 is fixedly connected to the other end of the curved tube 383 on the right side. The curved tube 383 communicates with the inner cavity of the ash storage box 51.

[0053] Further, installation grooves three 501 are provided on the lower part of the front side wall and the lower part of the rear side wall of the inner surface of the ash storage box 51. Rack bars 502 are fixedly connected to the bottom walls of the two installation grooves three 501. A hollow plate 503 is fixedly connected to the lower side of the middle part of the right end of the push plate 58. A driving rod 504 is rotatably connected to the inner surface of the hollow plate 503. Gears 505 are fixedly connected to the front end and the rear end of the driving rod 504. The two gears 505 are respectively engaged with the two rack bars 502. A plurality of springs 506 are fixedly connected in an annular array on the front part and the rear part of the outer surface of the driving rod 504. The other ends of the plurality of springs 506 are fixedly connected to rubber balls 507.

[0054] Further, the filtering assembly 54 includes a housing 541 fixedly connected to the common end of the two L-shaped tubes 53 close to each other. A filter element 542 is slidably connected to the inner surface of the housing 541. A baffle 543 is slidably connected to the inner surface of the housing 541. The baffle 543 is located behind the filter element 542. The two L-shaped tubes 53 both communicate with the inner cavity of the housing 541.

[0055] To achieve the above-mentioned spraying of dust into the gas pressure regulating station, the rectangular plate 50 can be pushed, so that the rectangular plate 50 drives the push rod 59 fixedly connected to it to slide into the inner cavity of the ash storage box 51. When the push rod 59 slides into the inner cavity of the ash storage box 51, the push plate 58 can be simultaneously pushed to slide in the inner cavity of the ash storage box 51. When the push plate 58 slides, the effect of pushing the gas in the inner cavity of the ash storage box 51 forward can be achieved;

[0056] The two L-shaped tubes 53 fixedly connected to the upper part of the outer surface of the ash storage box 51 can always keep the air pressure inside the ash storage box 51 consistent. When the push plate 58 is pushed forward, the dust in the inner cavity of the ash storage box 51 will be pushed from the ash storage box 51 into the curved tube 383 on the right side, and then enter the inner sleeve 382 from the curved tube 383 on the right side, and finally enter the inner cavity of the gas pressure regulating station through the connecting tube 381 on the right side;

[0057] During the process of pushing the push plate 58, the push plate 58 will drive the hollow plate 503 fixedly connected thereto to move. As described above, the driving rod 504 is rotatably connected to the inner surface of the hollow plate 503, and the gears 505 fixedly connected to the front end and the rear end of the driving rod 504 are respectively engaged with the racks 502 on the same side. The two racks 502 are respectively fixedly connected to the bottom walls of the third mounting grooves 501 on the same side. Therefore, while the hollow plate 503 moves, it can drive the driving rod 504 to rotate. When the driving rod 504 rotates, a plurality of springs 506 and rubber balls 507 fixedly connected to its surface can continuously strike the bottom wall of the ash storage box 51, so that the dust in the inner cavity of the ash storage box 51 is always in a lifted state, facilitating the subsequent addition of dust into the inner cavity of the gas pressure regulating station for airtightness detection;

[0058] During the process of pulling the push plate 58 back to its original position, at this time, the dust in the inner cavity of the ash storage box 51 will enter the inner cavity of the housing 541 from the L-shaped pipe 53 on the right side. The filter element 542 slidably installed in the inner cavity of the housing 541 plays a role of one-way filtration. Therefore, the dust can only be isolated in the L-shaped pipe 53 on the right side by the filter element 542 until the push plate 58 is pushed again, and the dust in the inner cavity of the L-shaped pipe 53 on the right side can be pushed into the ash storage box 51 again for subsequent airtightness detection;

[0059] When the filter element 542 needs to be replaced and dust needs to be added, only the baffle 543 needs to be pulled out from the housing 541, and then the filter element 542 can be replaced. When adding dust, only by opening the feeding pipe 57, the dust can be added into the ash storage box 51 from the feeding pipe 57, and the operation is simple and easy to master;

[0060] After the subsequent airtightness detection is completed, only the magnetic attraction block 7 needs to be pulled, so that the magnetic attraction block 7 adsorbs the ash scraping ring 391 and drives the ash scraping ring 391 to slide on the outer surface of the gas pressure regulating station. During the sliding process, a plurality of balls 393 roll on the surface of the gas pressure regulating station. The magnetic attraction block 7 is set with strong magnetism, and only the ash scraping ring 391 is made of an adsorbable material. Therefore, while the magnetic attraction block 7 adsorbs the ash scraping ring 391 and moves on the surface of the gas pressure regulating station, the dust on the surfaces of the transparent observation plate one 34, the transparent observation plate two 36 or the transparent observation plate three 37 can be scraped off for subsequent airtightness detection;

[0061] The magnetic attraction block 7 described above is a conventional setting in the prior art. In this solution, it only needs to satisfy the adsorption of the ash scraping ring 391 and drive the ash scraping ring 391 to slide. Therefore, the magnetic attraction block 7 is a conventional design in the prior art, and this solution will not be elaborated in detail.

[0062] The filter element 542 described above is a conventional setting in the prior art, and its working principle is as follows:

[0063] Definition of the filtration direction: The interior of the filter element 542 has a special channel structure or valve mechanism. These channels or valves are designed to allow fluid to enter from a specific side only and flow out to the other side, while preventing reverse flow. For example, the filter element 542 adopts a structure similar to a valve. When the fluid flows in the permitted direction, the valve opens to allow the fluid to pass through; when the fluid attempts to flow in the reverse direction, the valve closes to prevent the fluid from passing through.

[0064] Therefore, the filter element 542 is a conventional design in the prior art, and thus this solution will not be elaborated in detail herein.

[0065] It should be specifically noted that the specific installation method, circuit connection method, and control method of the spiral booster pump 385 adopted in the present invention are all conventional designs, and thus will not be elaborated in detail in the present invention.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all such changes and improvements fall within the scope of the present invention as claimed. The scope of the present invention as claimed is defined by the appended claims and their equivalents.
