Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, specifically a gas meter sealing detection device. Background Technology
[0002] In the production and quality control of gas meters, sealing testing is a crucial step in ensuring their performance and safety. Traditional gas meter sealing testing devices, while capable of performing basic testing functions to some extent, have revealed significant shortcomings in practical operation, particularly the lack of an effective fixing mechanism. This deficiency directly affects the accuracy and reliability of the test results.
[0003] Specifically, traditional testing devices lack a dedicated fixing mechanism to ensure the stability and position of the gas meter during the testing process. This unstable connection method can lead to two problems. First, the connection between the gas meter and the delivery pipes (including the inlet and outlet pipes) may be weak, easily loosening or falling off during testing, thus affecting the accuracy of the sealing test. Second, because the gas meter is not effectively fixed, it may experience slight displacement due to vibration or external interference during testing, further affecting the reliability of the test results. Utility Model Content
[0004] The purpose of this invention is to provide a gas meter sealing test device to solve the problems of the test devices mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas meter sealing performance testing device, comprising a testing base and two support plates fixedly connected to the top of the testing base. A gas storage tank is fixedly connected to the top of the two support plates, a connecting pipe is fixedly connected to one side of the gas storage tank, and a gas pump is fixedly connected to one end of the connecting pipe.

[0007] Preferably, the top ends of the multiple gas supply pipes are arranged in a straight line on the bottom of the gas storage tank, and the top ends of the multiple gas supply pipes are all fixedly connected to the bottom of the gas storage tank.

[0008] Preferably, the interior of the detection base is hollow, and the front of the detection base is made of transparent glass. Multiple partitions are fixedly connected inside the detection base, and the multiple partitions divide the internal space of the detection base into multiple detection spaces. The multiple detection spaces are filled with water, and one end of each of the multiple air outlets is located inside the multiple detection spaces.
[0009] Preferably, the clamping device includes a fixed plate, a threaded rod, a handle, a movable plate, a top rod, and a clamping plate. The top of the detection base is fixedly connected to the fixed plate, the top of the fixed plate is threadedly connected to the threaded rod, one end of the threaded rod is fixedly connected to the handle, and the other end of the threaded rod is fixedly connected to the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This device, through its design of a placement block containing multiple placement slots and corresponding gas supply and outlet pipes, enables simultaneous testing of multiple gas meters. This design not only significantly reduces the testing time for a single gas meter but also ensures the entire testing process is efficient and orderly. It is particularly suitable for the factory testing needs of large-scale production lines, significantly improving testing efficiency and reducing production costs.
[0014] 2. The clamping device employs a precise fit of components such as a threaded rod, a moving plate, a top rod, and a clamping plate to ensure the gas meter is securely held during testing. This design effectively prevents problems such as interface detachment or poor sealing caused by gas meter shaking, thereby ensuring the accuracy and stability of the test results and improving the reliability of the test data.
[0015] 3. By filling the test base with water and using a transparent glass front design, inspectors can directly observe the air bubbles produced at the gas outlet of each gas meter.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figure 1-4 This utility model provides a gas meter sealing test device, including a test base 1 and two support plates 2 fixedly connected to the top of the test base 1. A gas storage tank 3 is fixedly connected to the top of the two support plates 2. A connecting pipe 4 is fixedly connected to one side of the gas storage tank 3. A gas pump 5 is fixedly connected to one end of the connecting pipe 4. A placement block 9 is fixedly connected between the two support plates 2 on the top of the test base 1. Multiple gas meters 8 are movably connected to the top of the placement block 9. A gas supply pipe 6 is movably connected to the gas inlet end of each of the multiple gas meters 8, and a gas outlet pipe 7 is movably connected to the gas outlet end of each of the multiple gas meters 8. A clamping device for quickly fixing the multiple gas meters 8 is provided on the top of the test base 1.
[0023] Furthermore, the top of the placement block 9 is provided with multiple placement slots 10, and the multiple placement slots 10 are arranged in a straight line on the top of the placement slots 10, and the bottoms of the multiple gas meters 8 are respectively placed inside the multiple placement slots 10.
[0024] Furthermore, the top ends of multiple gas supply pipes 6 are arranged in a straight line on the bottom of the gas storage tank 3, and the top ends of multiple gas supply pipes 6 are all fixedly connected to the bottom of the gas storage tank 3. One end of multiple gas outlet pipes 7 is arranged in a straight line on one side of the detection base 1, and one end of multiple gas outlet pipes 7 is fixedly connected to one side of the detection base 1.
[0025] Furthermore, the interior of the detection base 1 is hollow, and the front of the detection base 1 is made of transparent glass. Multiple partition plates 11 are fixedly connected inside the detection base 1, and the multiple partition plates 11 divide the internal space of the detection base 1 into multiple detection spaces. The multiple detection spaces are filled with water, and one end of each of the multiple air outlet pipes 7 is located inside the multiple detection spaces.
[0026] Furthermore, the clamping device includes a fixed plate 12, a threaded rod 13, a handle 14, a movable plate 15, a push rod 16, and a clamping plate 18. The top of the detection base 1 is fixedly connected to the fixed plate 12, the top of the fixed plate 12 is threadedly connected to the threaded rod 13, one end of the threaded rod 13 is fixedly connected to the handle 14, and the other end of the threaded rod 13 is fixedly connected to the movable plate 15. One side of the movable plate 15 is fixedly connected to a plurality of push rods 16, and one end of each of the plurality of push rods 16 is fixedly connected to a clamping plate 18.
[0027] Furthermore, multiple clamping plates 18 are located inside multiple placement slots 10, and one end of multiple push rods 16 passes through the placement block 9 and is fixedly connected to one side of the multiple clamping plates 18.
[0028] Furthermore, multiple buffer springs 17 are fixedly connected between the placement block 9 and the moving plate 15, and the outer surfaces of the multiple push rods 16 are respectively located inside the multiple buffer springs 17.
[0029] In this embodiment, when a gas meter 8 needs to be tested for air tightness, multiple gas meters 8 are first placed into the placement slot 10 in sequence. Then, by turning the handle 14, the threaded rod 13 is rotated. Utilizing the threaded connection between the threaded rod 13 and the fixing plate 12, the threaded rod 13 pushes the moving plate 15 closer to the placement block 9. The moving plate 15 then moves multiple clamping plates 18 via multiple push rods 16, allowing the clamping plates 18 to fix and hold the gas meters 8 within the placement slots 10, ensuring stability during the gas meter air tightness test. During the movement of the moving plate 15 towards the placement block 9, multiple buffer springs 17 are compressed to prevent excessive pressure on the gas meters 8 caused by the moving plate 15 driving the clamping plates 18 via the push rods 16, thus preventing damage to the surface of the gas meters 8. Then, multiple gas supply pipes 6 are installed on the gas inlet ends of multiple gas meters 8 through connectors. Similarly, one end of multiple gas outlet pipes 7 is installed on the gas outlet ends of multiple gas meters 8 through interfaces. The multiple gas meters 8 are fixed by the clamping device, which can reduce the shaking of multiple gas meters 8 during the test, which could cause the interfaces between multiple gas supply pipes 6 and multiple gas outlet pipes 7 and multiple gas meters 8 to fall off, resulting in inaccurate air tightness. Then, the gas is transported to the inside of the gas storage tank 3 through the gas pump 5 via the connecting pipe 4. Then, the gas enters the inside of multiple gas meters 8 through multiple gas supply pipes 6. Then, the gas enters the water inside the test base 1 through multiple gas outlet pipes 7. The generation of bubbles can be observed through one side of the glass, thereby judging the air tightness of each gas meter 8 (no bubbles or a small number of bubbles indicate that the air tightness of the gas meter 8 is poor).

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
