Description

Technical Field

[0001] This utility model belongs to the field of reaction bottle technology, and specifically relates to a reaction bottle device with high sealing performance. Background Technology

[0002] When determining carbon and oxygen isotopes in rocks using the dual-injection method, the rock sample needs to be converted into carbon dioxide gas. This requires a special reaction flask device with high sealing performance. Currently available reaction flask devices consist of three parts: a cap, a rubber gasket, and the flask body. The cap has a circular perforation at the top, and the rubber gasket, 3mm thick and sized to match the size of the flask body at the mouth, ensures a complete fit and seal.

[0003] The specific process of the reaction flask device participating in the detection is as follows: First, place an appropriate amount of rock sample into the reaction flask and tighten the cap to seal the reaction flask. Then, a vacuum operation is performed on the reaction flask device. A vacuum needle is inserted into the reaction flask device through the rubber pad to remove the air inside the flask, and then the vacuum needle is withdrawn. The acid needle is inserted into the rubber pad and then into the reaction flask to add acid. The acid needle is then removed and left until the rock and acid have completely reacted and converted into carbon dioxide gas (at least 4 hours). The vacuum needle is inserted into the middle of the rubber pad, and the needle tip is sealed by the rubber pad. After the air in the vacuum needle and connecting tube is evacuated, the vacuum needle continues to enter the reaction flask device, and carbon dioxide gas is introduced into the mass spectrometry detection device for measurement.

[0004] The following problems exist during actual operation, resulting in poor sealing of the reaction flask apparatus: Firstly, the rubber gasket at the top of the reaction flask was punctured by a needle. Although the rubber gasket could recover and seal through its own elastic deformation, the vacuum inside the flask caused a pressure difference between the inside and outside of the reaction flask. The rubber gasket deformed and dented downwards under atmospheric pressure, resulting in poor sealing performance. Actual testing revealed that the vacuum level inside the flask did not meet the standard requirements.

[0005] Secondly, if the rubber gasket of the reaction flask is pierced by multiple needles, the structure of the rubber gasket will be damaged, and the sealing performance will be deteriorated.

[0006] Third, the acid may affect the structure of the rubber gasket during the acid addition process in the reaction vessel, thus causing the sealing performance of the reaction vessel to deteriorate.

[0007] To ensure the normal operation of carbon and oxygen isotope determination in rocks and to guarantee that the reaction flask apparatus meets the standard requirements for sealing, a reaction flask apparatus with high sealing performance is anticipated. Utility Model Content

[0030] The lower cap 1-2 is used to seal the bottle body 3 and, together with the upper cap 1-1, forms a closed space to further enhance the sealing effect. A lower rubber gasket 2-2 is installed inside the top of the lower cap 1-2, and the top of the lower cap 1-2 is open to facilitate the insertion of a vacuum needle into the lower rubber gasket 2-2.

[0031] The lower rubber gasket 2-2 is used to seal the enclosed space formed by the lower bottle cap 1-2 and the bottle body 3, and also to seal the enclosed space formed by the upper bottle cap 1-1 and the lower bottle cap 1-2.

[0032] Bottle 3 is used to fill the rock sample, which is the place where the sample reacts with the acid and stores the carbon dioxide gas after the reaction.

[0034] The bottom inner wall of the lower bottle cap 1-2 is connected to the outer wall of the bottle mouth of the bottle body 3 by a threaded structure.

[0035] The upper cap 1-1, the lower cap 1-2, and the bottle body 3 together constitute a high-sealing reaction bottle device, used to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0036] Specific examples, The upper bottle cap 1-1, together with the lower bottle cap 1-2, forms a closed space and serves as a seal. The top of the upper bottle cap 1-1 is fitted with an upper rubber gasket 2-1, and the top of the upper bottle cap 1-1 is hollowed out to facilitate the insertion of a vacuum needle into the upper rubber gasket 2-1.

[0037] The outer diameter of the upper bottle cap 1-1 is 19mm, and the diameter of the hollow part at the top is 8mm. The material is polypropylene.

[0038] The upper rubber gasket 2-1 is used to seal the enclosed space formed by the upper cap 1-1 and the lower cap 1-2. Located at the top inside the upper cap 1-1, it ensures the upper cap 1-1 functions as a seal, while allowing the vacuum needle to penetrate the rubber gasket and enter the reaction vessel apparatus. The upper rubber gasket 2-1 has a diameter of 17mm and a thickness of 3mm, and is made of polytetrafluoroethylene butyl rubber, offering good sealing performance and acid resistance.

[0039] The lower cap 1-2 seals the bottle body 3 and, together with the upper cap 1-1, forms a closed space to further enhance the sealing effect.

[0041] Bottle 3 is used to fill the rock sample, serving as the site for the sample's reaction with the acid and storing the resulting carbon dioxide gas. Bottle 3 is 40mm high and made of quartz glass.

[0042] The upper cap 1-1, the lower cap 1-2, and the bottle body 3 together constitute a high-sealing reaction bottle device, used to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0043] The principle of the high-sealing reaction flask device is as follows: After the sample is placed in the high-sealing reaction flask apparatus, the vacuum needle is inserted into the upper rubber pad 2-1 into the closed space formed by the upper cap 1-1 and the lower cap 1-2, without inserting into the lower rubber pad 2-2. This creates a vacuum in the space between the two caps. The vacuum needle then continues downwards into the lower rubber pad 2-2 and into the body 3, creating a vacuum within the body 3. The vacuum needle is then withdrawn. At this point, because the closed spaces within the two caps (upper cap 1-1 and lower cap 1-2) and the space within the body 3 are both under vacuum, the pressure difference between the upper and lower sides of the lower rubber pad 2-2 is consistent, preventing deformation. The lower rubber pad 2-2 maintains a good seal, thus ensuring a high degree of sealing for the sample before and after the reaction.

[0044] Example 2 Combination Figures 3-4 As shown, the high-sealing reaction flask device of the second embodiment of this utility model includes: The bottle cap 1 is used to seal the bottle body 3. It has two rubber pads inside (upper rubber pad 2-1 and lower rubber pad 2-2). The top of the bottle cap 1 is hollowed out, which makes it easy for the vacuum needle to insert into the upper rubber pad 2-1 and the lower rubber pad 2-2 into the bottle body 3.

[0045] The upper rubber pad 2-1 is used to form a closed space with the lower rubber pad 2-2, and at the same time serves a sealing function.

[0046] The lower rubber gasket 2-2 is used to seal the bottle body 3 and the enclosed space formed by the upper rubber gasket 2-1.

[0047] Bottle 3 is used to fill the rock sample, which is the place where the sample reacts with the acid and stores the carbon dioxide gas after the reaction.

[0048] The cap 1 and the body 3 together form a high-sealing reaction bottle device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0049] Specific examples, Bottle cap 1 is used to seal bottle body 3. It contains two rubber gaskets (upper rubber gasket 2-1 and lower rubber gasket 2-2). The top of bottle cap 1 is perforated to facilitate the insertion of a vacuum needle into the upper rubber gasket 2-1 and lower rubber gasket 2-2 into the bottle body 3. Bottle cap 1 is a custom-made cap with a height of 18mm, capable of accommodating both upper and lower rubber gaskets 2-1 and 2-2. The outer diameter of bottle cap 1 is 17mm, the inner diameter is 15mm, and the diameter of the perforated portion at the top is 8mm. It is made of polypropylene.

[0050] The upper rubber gasket 2-1, together with the lower rubber gasket 2-2, forms a closed space and serves a sealing function. The upper rubber gasket 2-1 is a custom-made rubber gasket with a circular top and a ring-shaped cylinder at the bottom, located inside the top of the bottle cap. The circular top of the upper rubber gasket 2-1 has a diameter of 15mm and a thickness of 3mm. The ring-shaped cylinder has an outer diameter of 15mm, an inner diameter of 9mm, and a height of 3mm. It is made of polytetrafluoroethylene butyl rubber, offering good sealing performance and acid resistance.

[0051] The lower rubber gasket 2-2 is used to seal the bottle body 3, sealing the enclosed space formed by the upper rubber gasket 2-1. The lower rubber gasket 2-2 has a diameter of 15mm and a thickness of 3mm, and is made of polytetrafluoroethylene butyl rubber, which has good sealing performance and acid resistance.

[0052] Bottle 3 is used to fill the rock sample, serving as the site for the sample's reaction with the acid and storing the resulting carbon dioxide gas. Bottle 3 is 40mm high and made of quartz glass.

[0053] The cap 1 and the body 3 together form a high-sealing reaction bottle device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0054] The principle of the high-sealing reaction flask device is as follows: After the sample is placed in the high-sealing reaction flask apparatus, the vacuum needle is inserted into the upper rubber pad 2-1, entering the sealed space formed by the upper rubber pad 2-1 and the lower rubber pad 2-2, without inserting into the lower rubber pad 2-2. The sealed space between the two rubber pads is then evacuated. The vacuum needle is then inserted further into the lower rubber pad 2-2 and into the flask body 3, evacuating the space inside the flask body 3 until it is completely evacuated. At this point, because both the sealed space between the two rubber pads and the space inside the flask body 3 are under vacuum, the pressure difference between the upper and lower sides of the lower rubber pad 2-2 is consistent, preventing deformation. The lower rubber pad 2-2 maintains a good seal, thus ensuring a high degree of sealing for the sample before and after the reaction.

[0055] Example 3 Combination Figures 5-6 As shown, the high-sealing reaction flask device of the third embodiment of this utility model includes: The bottle cap 1 is used to seal the bottle body 3. There is an upper rubber gasket 2-1 on the top inside. The top of the bottle cap 1 is hollowed out to facilitate the insertion of a vacuum needle into the upper rubber gasket 2-1.

[0056] The upper rubber gasket 2-1 is used to seal the enclosed space formed by the bottle cap 1 and the bottle body 3.

[0057] Bottle 3 is used to fill the rock sample, which is the place where the sample reacts with the acid and stores the carbon dioxide gas after the reaction.

[0058] A sealing device is used to seal the space below the bottle neck. The sealing device consists of a steel rod 5 and a lower rubber pad 2-2. The steel rod 5 is embedded and fixed inside the lower rubber pad 2-2, which moves the lower rubber pad 2-2 up and down.

[0059] The cap 1, body 3, and sealer together constitute a high-sealing reaction flask device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction flask device can maintain a vacuum state before the sample reaction and prevent air from entering the flask after the sample reaction.

[0060] Specific examples, Bottle cap 1 is used to seal bottle body 3. There is an upper rubber gasket 2-1 on the top inside the bottle cap 1.

The outer diameter of bottle cap 1 is 13mm, the inner diameter is 11mm, the diameter of the hollowed-out part at the top is 6mm, and the material is polypropylene.

[0061] The upper rubber gasket 2-1 is used to seal the enclosed space formed by the bottle cap 1 and the bottle body 3. The upper rubber gasket 2-1 has a diameter of 11mm and a thickness of 3mm, and is made of polytetrafluoroethylene butyl rubber, which has good sealing performance and acid resistance.

[0062] Bottle 3 is used to fill the rock sample, serving as the site for the sample's reaction with the acid and storing the resulting carbon dioxide gas. Bottle 3 is a custom-made glass bottle with a smaller diameter at the mouth and a larger diameter below the mouth. The inner diameter at the mouth of bottle 3 is 9mm, and the height is 8mm; the height of the bottle body excluding the mouth is 35mm, and the material is quartz glass.

[0063] The sealing device is used to seal the space below the bottle neck. It consists of a steel rod 5 and a lower rubber pad 2-2. The steel rod 5 is embedded and fixed within the rubber pad, causing the lower rubber pad 2-2 to move up and down. The steel rod 5 has a diameter of 1mm, is made of steel, and has an acid-resistant coating. The lower rubber pad 2-2 has a diameter of 9.2mm and a thickness of 3mm, and is made of polytetrafluoroethylene butyl rubber, providing good sealing and acid resistance.

[0064] The cap 1, body 3, and sealer together constitute a high-sealing reaction flask device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction flask device can maintain a vacuum state before the sample reaction and prevent air from entering the flask after the sample reaction.

[0065] The principle of the high-sealing reaction flask device is as follows: After the sample is placed into the high-sealing reaction flask apparatus, the lower rubber pad 2-2 is moved downwards from the flask opening to the wider part of the flask body using the steel rod 5. Then, a vacuum needle is inserted into the upper rubber pad 2-1 and into the flask body 3 to create a vacuum inside the flask body 3. After the vacuum needle is removed, the lower rubber pad 2-2 is moved upwards to the flask opening to form a seal. Because the flask body 3 is in a vacuum state, the pressure difference between the upper and lower sides of the lower rubber pad 2-2 of the sealer is consistent, with no deformation effect. Furthermore, the lower rubber pad 2-2 has no pinholes, maintaining the original sealing structure. Therefore, it is ensured that the sample remains in a high-sealing state before and after the reaction. Example 4 Combination Figures 7-8 As shown, the high-sealing reaction flask device of the fourth embodiment of this utility model includes: Bottle cap 1 is used to seal bottle body 3. There is an upper rubber pad 2-1 inside the top of bottle cap 1. At the same time, the top of bottle cap 1 is hollowed out to facilitate the vacuum needle to insert into the upper rubber pad 2-1.

[0066] The upper rubber gasket 2-1 is used to seal the enclosed space formed by the bottle cap 1 and the bottle body 3.

[0067] Bottle 3 is used to fill the rock sample, which is the place where the sample reacts with the acid and stores the carbon dioxide gas after the reaction.

[0068] The secondary sealing assembly, used to enhance the sealing ability of bottle cap 1, consists of a lower rubber pad 2-2, a telescopic rod 4-1, a spring 4-2, and a guide rod cylinder 4-3.

[0069] The lower rubber pad 2-2 is used to directly act on the upper rubber pad 2-1, press against the upper rubber pad 2-1, reduce the deformation of the upper rubber pad 2-1 after vacuuming, and at the same time stick to the upper rubber pad 2-1 to block the pinhole.

[0070] The telescopic rod 4-1 is used to push the lower rubber pad 2-2 upwards to fit against the upper rubber pad 2-1, or to retract the lower rubber pad 2-2 downwards when the vacuum needle enters the bottle body 10. The telescopic rod 4-1 is fixedly connected to the lower rubber pad 2-2.

[0071] Spring 4-2 is used to extend telescopic rod 4-1 upwards, or to ensure that telescopic rod 4-1 retracts when vacuum needle enters bottle body 3.

[0072] The guide rod cylinder 4-3 is used to ensure that the telescopic rod 4-1 and the spring 4-2 are in a straight line when they are in action.

[0073] The cap 1, body 3, and secondary sealing assembly together constitute a high-sealing reaction bottle device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0074] Specific examples, Bottle cap 1 is used to seal bottle body 3. There is an upper rubber gasket 2-1 on the inner top. The top of bottle cap 1 is hollowed out to facilitate the insertion of a vacuum needle into the upper rubber gasket 2-1. The outer diameter of bottle cap 1 is 17mm, the inner diameter is 15mm, the diameter of the hollowed-out part at the top is 8mm, and the material is polypropylene.

[0075] The upper rubber gasket 2-1 is used to seal the enclosed space formed by the bottle cap 1 and the bottle body 3. The upper rubber gasket 2-1 has a diameter of 15mm and a thickness of 3mm, and is made of polytetrafluoroethylene butyl rubber, which has good sealing performance and acid resistance.

[0076] Bottle 3 is used to fill the rock sample, serving as the site for the sample's reaction with the acid and storing the resulting carbon dioxide gas. Bottle 3 is 40mm high and made of quartz glass.

[0077] The secondary sealing assembly, used to enhance the sealing ability of bottle cap 1, consists of a lower rubber pad 2-2, a telescopic rod 4-1, a spring 4-2, and a guide rod cylinder 4-3. The spring 4-2 of the secondary sealing assembly is in a semi-compressed, energy-storing state. The guide rod cylinder 4-3 ensures that the telescopic rod 4-1 generates a vertically upward force, resulting in a pressure of approximately 0.9 atmospheres exerted by the lower rubber pad 2-2 on the upper rubber pad 2-1.

[0078] The lower rubber pad 2-2 acts directly against the upper rubber pad 2-1, supporting it and reducing its deformation under vacuum. It also seals the upper rubber pad 2-1 to block the pinhole. The lower rubber pad 2-2 has a diameter of 8mm and a thickness of 2mm, and is made of polytetrafluoroethylene butyl rubber, offering good sealing and acid resistance.

[0079] Telescopic rod 4-1 is used to push the lower rubber pad 2-2 upwards to fit it against the upper rubber pad 2-1, or to retract the lower rubber pad 2-2 downwards when the vacuum needle enters the bottle body 10. Telescopic rod 4-1 is fixedly connected to the lower rubber pad 2-2. Telescopic rod 4-1 is 25mm long and 5mm in diameter, made of polytetrafluoroethylene (PTFE), and has good acid resistance.

[0080] Spring 4-2 is used to extend the telescopic rod 4-1 upwards, or to ensure that the telescopic rod 4-1 retracts when the vacuum needle enters the bottle body 3. Spring 4-2 is 20mm long in its normal state, made of steel, and has an acid-resistant coating. In a semi-compressed state, it can generate approximately 0.9 atmospheres of pressure on the rubber pad 13-1.

[0081] The guide rod cylinder 4-3 is used to ensure that the telescopic rod 4-1 and the spring 4-2 are in a straight line when they are in action. The guide rod cylinder 4-3 has an outer diameter of 6mm, an inner diameter of 5.5mm, and a height of 30mm. The base has a diameter of 10mm and a height of 2mm. The entire structure is made of polytetrafluoroethylene, which has good acid resistance.

[0082] The cap 1, body 3, and secondary sealing assembly together constitute a high-sealing reaction bottle device to ensure that the sample is in a highly sealed state before and after the reaction. As a high-sealing system, the high-sealing reaction bottle device can maintain a vacuum state before the sample reaction and prevent air from entering the bottle after the sample reaction.

[0083] The principle of the high-sealing reaction flask device is as follows: When the sample is placed into the high-sealing reaction flask, the vacuum needle penetrates the upper rubber pad 2-1 and enters the flask body 3. The vacuum needle acts on the lower rubber pad 2-2 of the secondary sealing component. Since the spring 4-2 is in a semi-compressed state, it can be further compressed, and the vacuum needle fully enters the flask body 3, creating a vacuum inside the flask body 3. After completion, the vacuum needle withdraws, and the spring rebounds and the telescopic rod 4-1 adheres to and presses against the upper rubber pad 2-1. At this time, the pressure difference between the upper and lower sides of the upper rubber pad 2-1 is inconsistent, and it will deform downward under atmospheric pressure. Because the lower rubber pad 2-2 generates 0.9 atmospheres of pressure on the upper rubber pad 2-1 under the action of the spring 4-2 and the telescopic rod 4-1, it greatly reduces the downward deformation of the upper rubber pad 2-1, almost maintaining the original sealing state of the upper rubber pad 2-1, ensuring that the sample can be in a high-sealing state before and after the reaction.

[0084] The four high-sealing reaction bottle devices proposed in this invention for determining stable carbon and oxygen isotopes in rocks using a dual-injection system maintain a consistent pressure difference on both sides of the rubber gasket or significantly reduce the deformation of the sealing rubber gasket using mechanical principles, thereby ensuring that the rubber gasket maintains its original sealing state and that no air enters during the experiment, thus guaranteeing the accuracy of the experimental results.
