Description

Technical Field

[0001] This utility model relates to the field of gas chromatograph leak detection technology, specifically a gas chromatograph leak detection device. Background Technology

[0002] A gas chromatograph is a chromatographic analysis instrument that uses gas as the mobile phase. Gas chromatographs are widely used in current experimental research. They are supplied with gas by a hydrogen generator. When checking for leaks in the gas chromatograph pipeline, soap solution is usually applied to the pipeline interface and the outer wall of the pipeline. After the gas is turned on, the presence of bubbles in the soap solution is observed to determine whether there is a leak.

[0003] A search revealed that patent publication number CN218916702U discloses a leak detection device for gas chromatographs. This device allows for back-and-forth movement of the detection unit, eliminating the need for operators to manually apply soap solution to the gas outlet tube. By using clamps, the gas outlet tube is clamped, and the soap solution is applied. The soap solution flows through a flexible tube to a sliding seat, then into the clamps. The soap solution then penetrates the sponge layer at the clamps, which wraps around the gas tube, thus applying the soap solution to the outlet tube. Operators can locate the leak by observing where bubbles appear, thus solving the problem of low leak detection efficiency in some existing gas chromatograph leak detection devices.

[0004] However, the applicant found that it was difficult to observe whether there were bubbles in the soap solution at the bottom of the vent pipe and on the outer wall of the rear side during actual use, and the clamp also blocked the observation of the vent pipe, thus affecting the efficiency of leak detection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a gas chromatograph leak detection device, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas chromatograph leakage detection device, comprising a hydrogen generator, a gas chromatograph, and an outlet pipe disposed between the hydrogen generator and the gas chromatograph, wherein a soap application mechanism is connected between the hydrogen generator and the gas chromatograph.

[0007] The soap application mechanism includes a soap tank located between a hydrogen generator and a gas chromatograph. The soap tank is equipped with an electric guide rail, and the output end of the electric guide rail is equipped with a mounting rod. Movable components are provided on both sides of the bottom of the mounting rod. Clamping blocks are provided on the movable components. The inside of the clamping blocks is equipped with a sponge layer that fits against the gas outlet pipe. The top of the clamping blocks is connected to a telescopic hose, and the top of the telescopic hose is connected to a pump connected to the soap tank.

[0008] A mirror is installed between the hydrogen generator and the gas chromatograph, located below the gas outlet pipe, and a second mirror is installed vertically at the rear end of the first mirror.

[0009] Preferably, the movable component includes an electric push rod mounted on a mounting rod, an installation block is provided on the output end of the electric push rod, an electric telescopic rod is provided on the mounting block, and the output end of the electric telescopic rod is connected to a clamping block.

[0010] Preferably, the first mirror is tilted downwards from back to front, and a collection tank is provided between the hydrogen generator and the gas chromatograph located below the first mirror.

[0014] Beneficial effects

[0015] This invention provides a leak detection device for a gas chromatograph. Compared with the prior art, it has the following advantages:

[0016] 1. The gas chromatograph uses a leak detection device. After the moving mechanism moves the clamp away from the gas outlet pipe, it moves above the gas outlet pipe so as not to obstruct the observation of the gas outlet pipe.

[0017] 2. The gas chromatograph uses a leak detection device, which allows for easy observation of the bottom of the gas outlet tube and the outer wall of the rear side through the reflection of mirror one and mirror two; by setting up a scraping mechanism, the soap liquid falling on mirror one can be scraped off, which is more conducive to the observation of the image reflected by mirror one.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A gas chromatograph leak detection device includes a hydrogen generator 1, a gas chromatograph 2 and an outlet pipe 3 disposed between the hydrogen generator 1 and the gas chromatograph 2, and a soap application mechanism is connected between the hydrogen generator 1 and the gas chromatograph 2.

[0026] The soap application mechanism includes a soap tank 5 located between the hydrogen generator 1 and the gas chromatograph 2. The soap tank 5 is equipped with a liquid inlet for adding prepared soap solution. The soap tank 5 is equipped with an electric guide rail 6. The output end of the electric guide rail 6 is equipped with a mounting rod 7, which can drive the mounting rod 7 to move laterally. The bottom sides of the mounting rod 7 are equipped with moving components. The moving components are equipped with clamping blocks 8. The inside of the clamping blocks 8 is equipped with a sponge layer 9 that fits against the gas outlet pipe 3. The top of the clamping blocks 8 is connected to a telescopic hose 10, and the top of the telescopic hose 10 is connected to a pump 11 connected to the soap tank 5.

[0027] A mirror 12 is installed between the hydrogen generator 1 and the gas chromatograph 2, located below the gas outlet pipe 3. A mirror 2 13 is vertically installed at the rear end of the mirror 12. Through the reflection of the mirror 12 and the mirror 2 13, the bottom and rear outer wall of the gas outlet pipe 3 can be observed without much effort.

[0028] The movable component includes an electric push rod 14 mounted on the mounting rod 7. A mounting block 15 is mounted on the output end of the electric push rod 14, which can drive the mounting block 15 to rise and fall. An electric telescopic rod 16 is mounted on the mounting block 15. The output end of the electric telescopic rod 16 is connected to the clamping block 8, which can drive the clamping block 8 to move back and forth.

[0029] Soap liquid will fall onto the mirror 12 on the gas outlet pipe 3 and the sponge layer 9, causing the mirror 12 to be tilted downwards from back to front, so that it can be easily washed away by gravity. A collection tank 17 is provided between the hydrogen generator 1 and the gas chromatograph 2, located below the mirror 12, to collect the falling soap liquid.

[0030] The mirror 12 is equipped with a scraping mechanism to remove soap residue adhering to it. The scraping mechanism includes a track 18 mounted on the hydrogen generator 1 and the gas chromatograph 2. The track 18 is slidably connected to a slide rod 19. A spring 20 is mounted at the bottom of the slide rod 19. A scraper 21 that fits against the mirror 12 is mounted at the bottom of the spring 20. A movable rod 22 that passes through the slide rod 19 is mounted at the top of the scraper 21 to guide it. A handle 23 is mounted on the front side of the scraper 21. By pulling the handle 23, the scraper 21 moves downward along the mirror 12 to scrape off the residual soap residue on the surface, ensuring the mirror 12 is smooth and thus facilitating observation.

[0031] The second implementation differs from the first implementation in that: mirror 12 and mirror 23 are respectively provided with mirror 3 24 and mirror 4 25 on both sides. Mirror 3 24 is connected to hydrogen generator 1, and mirror 4 25 is connected to gas chromatograph 2. This prevents soap solution from flowing to both sides of mirror 12 when the scraper 21 moves downward. Furthermore, the reflection from mirror 3 24 and mirror 4 25 facilitates further observation of the gas outlet pipe 3.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] In use, gas is supplied to the outlet pipe 3 through the hydrogen generator 1, while the sponge layer 9 moves back and forth laterally to apply soap solution to the outlet pipe 3. After application, the sponge layer is first moved away from the outlet pipe 3 by the electric telescopic rod 16, and then moved upward by the electric push rod 14, so that it is positioned above the outlet pipe 3. With the reflection of mirror 12 and mirror 23, the outside of the outlet pipe 3 can be fully observed. During observation, the handle 23 can be used to pull the scraper 21 to scrape off the soap solution on mirror 12. After scraping, if soap solution continues to drip, the slide rod 19 can be reinstalled along the track 18, and the scraper 21 can be lifted upward to compress the spring 20. This way, when the scraper 21 moves to the top rear end of mirror 12, the scraper 21 will not touch mirror 12, avoiding pushing the soap solution to the back. Through comprehensive observation of the outlet pipe 3 and cleaning of mirror 12, the leakage detection of the outlet pipe 3 is highly efficient and effective.
