[0018] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] like Figures 1-2 As shown, a bulging exhaust gas release and collection device includes a gas collection device, a control valve 200, and a valve nozzle 300 with an internal valve core, all detachably connected in sequence. A needle tube 400 for inserting into a storage bag is fixedly connected to the bottom end of the valve nozzle 300. When exhaust gas is generated inside the storage bag, causing a bulge, the needle tube 400 is inserted into the bulging storage bag, the control valve is opened, and the storage bag is collected into the gas collection device. When the gas collection device is full, it can be removed, and the remaining exhaust gas in the storage bag can be directly vented. The collected gas is then analyzed to determine its composition. This bulging exhaust gas release and collection device has a simple structure, reasonable design, is convenient to use, and easy to operate, enabling rapid collection and release of exhaust gas from the storage bag.

[0021] In this embodiment, in order to ensure the airtightness between the syringe and the storage bag, the syringe 400 and the storage bag 800 are sealed and fixedly connected by adhesive or tape. After the gas collection box is released, the syringe 400 can remain on the storage bag. Since the syringe 400 is connected to the valve 300, the valve core inside the valve 300 can automatically close, ensuring the airtightness of the storage bag 800.

[0022] In this embodiment, the gas collection device is a gas sampling bag; in specific implementation, a gas collection bottle, gas collection tank, etc., may also be used.

[0023] In this embodiment, in order to achieve quick assembly and disassembly, one port of the control valve 200 is connected to the valve body via the inflation clamp 500, and the other port of the control valve 200 is connected to the gas sampling bag via the quick connector 600 and the connecting pipe.

[0024] In this embodiment, the gas sampling bag 100 is provided with a valve 110, and the valve nozzle is connected to the connecting pipe 700.

[0025] In this embodiment, the gas sampling bag 100 is an aluminum foil gas sampling bag.

[0026] In this embodiment, the control valve 200 is a manual valve, specifically a lever-type manual valve, and the model can be TAC-3V.

[0027] In this embodiment, the inflation clamp 500 is a self-locking inflation clamp with a normally closed structure. One end of the self-locking inflation clamp is a circular self-locking head, which is used to connect the valve body. The valve body is inserted into the inflation clamp to achieve the connection. The other end is an internal thread, which is used to connect to the control valve interface.

[0028] In this embodiment, the quick-connect connector 600 is a PC threaded straight connector, with one end being a PC interface for connecting to the connecting pipe and the other end being a threaded port for connecting to the control valve interface.

[0029] The specific working process of this bulging exhaust gas release and collection device is as follows: Connect the nozzle of the valve with the needle to the inflation clamp, and connect the gas collection bag to the connecting tank. When exhaust gas is generated inside the storage bag and bulges, insert the needle into the bulging storage bag, and seal and fix the needle and storage bag with adhesive or tape. Open the control valve, and the storage bag collects the gas into the gas collection bag. When the gas collection bag is full, if the amount of gas collected is insufficient, the control valve can be closed and the gas collection bag replaced to continue collecting. If the amount of gas collected is sufficient, the gas collection bag can be removed, and the remaining exhaust gas in the storage bag can be directly vented through the connecting pipe. The collected gas is then analyzed to determine its composition. After the gas collection and emission work is completed, the nozzle is separated from the inflation clamp, and the nozzle and needle can remain on the storage bag for the next collection and emission operation.

[0030] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0031] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0032] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0033] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
