TECHNICAL FIELD
[0001] The present application relates to the technical field of chemical experiment equipment, in particular to an explosion-proof bottle cap for a reaction tube. BACKGROUND
[0002] The reaction tube is an indispensable core instrument in chemical experiments, which provides a closed and controllable environment for synthesis reactions, so that the reactants can be mixed, transformed and reacted under specific conditions, and therefore is frequently used in laboratories. When performing a synthesis reaction, a researcher usually places the weighed reactants in a reaction tube, then adds an appropriate amount of solvent to promote the dissolution and mixing of the reactants, and then covers the bottle cap, places the reaction tube in a heating module or a reaction kettle for reaction, so as to ensure that there is no interference from external substances during the reaction, and also provides a safe container for volatile substances that may be generated.
[0003] However, during the reaction, due to the generation of gas or the rise of high temperature in the reaction tube, the pressure in the reaction tube increases, and in such a closed environment, the change of pressure is easy to cause the reaction tube to burst under pressure, and even cause an explosion. Such a dangerous situation not only causes serious damage to experimental equipment, but more importantly, it brings great safety risks to the experimenter.
[0004] According to the related technology in the above, the inventors believe that there is a risk of explosion of the reaction tube when performing chemical experiments. CONTENT OF THE INVENTION
[0005] In order to improve the safety of experiments, the present application provides an explosion-proof bottle cap for a reaction tube.
[0006] The explosion-proof bottle cap for a reaction tube provided by the present application adopts the following technical solution:
[0007] An explosion-proof bottle cap for a reaction tube, comprising a cap body, a through hole is formed in the cap body, and a gas permeable gasket for sealing the cap body is embedded on the cap body.
[0008] Through the above technical solution, when the internal pressure of the reaction tube increases due to the generation of gas or the rise of temperature, the pressure in the reaction tube is discharged to the outside through the gas permeable gasket, thereby effectively avoiding the risk of explosion of the reaction tube due to excessive pressure; the use of the gas permeable gasket also realizes the sealing of the reaction tube, ensuring the smooth progress of the reaction; through the cooperation of the through hole and the gas permeable gasket, the internal pressure of the reaction tube is regulated and controlled, effectively avoiding the explosion accident caused by excessive pressure.
[0009] Preferably, the hole wall of the through hole gradually decreases from the inside to the outside.
[0010] By the technical scheme, the resistance of the gasket is reduced, when the pressure in the reaction tube is abnormally increased, the gas permeable gasket can be more easily flushed out along the gradually reduced hole wall under the action of the pressure, so that the pressure relief process is more rapid, thereby avoiding the risk of explosion of the reaction tube due to excessive pressure, providing higher safety for the experimenters, meanwhile, the gradually reduced hole wall from inside to outside avoids the impact and danger caused by the sudden outflow of a large amount of gas, ensuring the stability and safety of the pressure relief process.
[0011] Preferably, the gas permeable gasket comprises a body and an annular elastic member arranged on the circumferential side of the body.
[0012] By adopting the technical scheme, when the synthesis experiment is performed, the annular elastic member is tightly attached to the inner wall of the cover, thereby realizing the stable connection between the gas permeable gasket and the cover, when the pressure in the reaction tube is sharply increased, the annular elastic member is deformed by elastic force and no longer forms a sealed connection with the inner wall, thereby causing the entire gas permeable gasket to be rapidly flushed out of the cover, effectively releasing the pressure, thereby ensuring the safety of the experimenters.
[0013] Preferably, a pressure relief groove is arranged on the gas permeable gasket to facilitate pressure relief.
[0014] The pressure relief groove is in a closed state in a natural state, and when subjected to pressure, the pressure relief groove is bulged outward by expansion and contraction of the gas permeable gasket.
[0015] By adopting the technical scheme, in a natural state, the gas permeable gasket can be tightly closed to effectively isolate the internal and external environments of the reaction tube, when the pressure in the reaction tube is increased, the gas permeable gasket is bulged outward by expansion and contraction to drive the pressure relief groove to open, so that the pressure is discharged to the outside, thereby reducing the pressure in the bottle and avoiding the phenomenon of ejection of reactants due to a sharp increase in pressure, and also significantly relieving the risk of bottle explosion caused by excessively high pressure.
[0016] Preferably, the pressure relief groove is in a cross shape.
[0017] By adopting the technical scheme, the cross-shaped pressure relief groove can effectively disperse the pressure impact while ensuring smooth discharge of the gas, preventing the gas permeable gasket from being damaged due to excessive force on a single point, in addition, this design also enables the gas permeable gasket to expand more uniformly when subjected to pressure, further improving the pressure relief efficiency and safety thereof.
[0018] Preferably, the pressure relief groove is in a river shape.
[0019] By adopting the technical scheme, the high-pressure gas can be rapidly dispersed and discharged when passing through, thereby ensuring rapid reduction of the pressure in the reaction tube, and the river-shaped pressure relief groove can also effectively disperse the pressure on the gas permeable gasket, thereby avoiding damage to the gasket due to concentrated pressure, thereby improving the durability of the gas permeable gasket.
[0020] Preferably, the cover is provided with a notch, and the air permeable gasket is embedded in the upper end surface of the cover through the notch.
[0021] By adopting the above technical scheme, when the internal pressure of the reaction tube is too large, the air permeable gasket is arranged on the upper end surface of the cover, so that the air permeable gasket is more easily blown out by high-pressure gas, thereby releasing the internal pressure in time, avoiding the explosion accident caused by the high pressure of the reaction tube, and thus ensuring the safety of the experimenters.
[0022] Preferably, the edge portion of the notch is inwardly inclined.
[0023] By adopting the above technical scheme, the notch inwardly inclines and presses the air permeable gasket, so that the connection between the air permeable gasket and the cover is more closely and stably, thereby ensuring the good sealing performance of the reaction tube in the normal state. In addition, the design of the notch makes the installation and disassembly of the gasket more convenient, and improves the work efficiency.
[0024] Preferably, the outer wall of the cover is provided with anti-slip texture for increasing friction.
[0025] By adopting the above technical scheme, when it is necessary to twist or disassemble the cover, the force can be more easily applied, thereby effectively avoiding the accidental falling or damage caused by hand slipping, and improving the convenience and safety of the operation of the device.
[0026] Preferably, the inner wall of the cover is provided with a thread for sealing connection with the reaction tube.
[0027] By adopting the above technical scheme, the threaded connection of the cover and the reaction tube is ensured, the connection stability is improved, and the sealing performance of the reaction is enhanced, thereby preventing the leakage of gas or liquid during the reaction, and making the installation and disassembly process of the cover more convenient and fast.
[0028] In summary, the present application has the following at least one beneficial technical effect:
[0029] 1. The present application realizes the discharge of the internal pressure of the reaction tube by opening a through hole on the cover and embedding an air permeable gasket on the cover, avoids the explosion risk of the reaction tube caused by pressure accumulation, and ensures the safety and stability of the experimental process.
[0030] 2. The present application avoids the phenomenon that the reactants are sprayed due to the dramatic increase of pressure by arranging a pressure relief groove on the air permeable gasket, effectively disperses the pressure received by the air permeable gasket, thereby reducing the damage of the gasket caused by the concentration of pressure, and improving the pressure relief efficiency and safety.
[0031] 3. The application sets anti-skid texture and thread on the inner wall and outer wall of the cover body respectively, enhances the friction and connection stability between the cover body and the reaction tube, makes the installation and dismounting process of the cover body more convenient and efficient, and improves the overall sealing performance and use convenience of the equipment.

[0040] The application will be further described below in combination with the drawings. Figures 1-7 The application will be further described below in combination with the drawings.
[0041] The embodiment of the application discloses an explosion-proof bottle cover for a reaction tube.
[0042] Embodiment 1, referring to Figure 1 and Figure 2 , comprising a cover body 1, a through hole 2 and an air permeable gasket 3, the cover body 1 is a circular device matched with the mouth of the reaction tube, the through hole 2 is provided through the cover body 1, the air permeable gasket 3 is embedded in the cover body 1, and the air permeable gasket 3 is closely arranged with the through hole 2.
[0043] In the synthesis experiment, the raw materials and solvents are sequentially added into the reaction tube according to the operation steps, the air permeable gasket 3 is embedded into the cover 1, then the cover 1 is covered, and the reaction tube is placed in the heating module or the reaction kettle for reaction. When the internal pressure of the reaction tube increases during the reaction, the high-pressure gas in the reaction tube is discharged to the outside through the air permeable gasket 3, thereby reducing the pressure in the bottle and avoiding the risk of explosion of the reaction tube due to excessive internal pressure.
[0044] To further improve the practicability and use convenience of the cover 1, with reference to Figure 2 , the anti-slip texture 6 is arranged on the outer peripheral side of the cover 1, and the thread 7 is arranged on the inner wall peripheral side of the cover 1. In the synthesis experiment, the thread 7 is arranged to realize the threaded connection of the cover 1 and the reaction tube, thereby ensuring the sealing property during the reaction. After the reaction is completed, the system is cooled to room temperature, the cover 1 is unscrewed for post-treatment of the reaction liquid, and the anti-slip texture 6 arranged on the outer wall peripheral side of the cover 1 improves the friction when the cover 1 is held, so that the researcher can more efficiently and conveniently disassemble the cover 1.
[0045] The working process and implementation principle of the explosion-proof bottle cover in Example 1 are as follows: the through hole 2 is arranged on the cover 1, and the air permeable gasket 3 is used in cooperation with the through hole 2, which not only ensures good sealing property to enable the reaction to proceed smoothly, but also enables timely pressure relief when the internal pressure of the reaction tube is too high, thereby avoiding explosion of the reaction tube; the anti-slip texture 6 and the thread 7 are arranged on the inner and outer walls of the cover 1, respectively, which enhances the connection stability of the cover 1 and the reaction tube, and also makes the disassembly of the cover 1 more convenient, thereby improving the practicability and use convenience of the equipment.
[0046] In Example 2, with reference to Figure 3 and Figure 4 , the difference between this embodiment and Example 1 is that it is suitable for violent chemical reactions: the inner wall of the through hole 2 gradually decreases from the inside to the outside, the air permeable gasket 3 includes a gasket body 31 and an annular elastic member 32, the gasket body 31 is arranged in cooperation with the through hole 2, and the annular elastic member 32 is arranged on the peripheral side of the body 31 and abuts against the inner wall end face of the cover 1; in the synthesis experiment, the researcher embeds the air permeable gasket 3 into the cover 1, and uses the annular elastic member 32 to tightly adhere to the inner wall of the cover 1. When the internal pressure of the reaction tube is too high, the high-pressure gas in the tube first impacts the body 31, drives the annular elastic member 32 to deform in elasticity and no longer sealingly connects with the cover 1, and then makes the entire air permeable gasket 3 quickly rush out of the cover 1, thereby effectively releasing the pressure and protecting the safety of the experimenter.
[0047] The working process and implementation principle of the explosion-proof bottle cap in embodiment 2 are as follows: the annular elastic member 32 is tightly attached to the inner wall of the cap body 1, thereby realizing the stable connection between the air permeable gasket 3 and the cap body 1; when the pressure in the reaction tube is too high, the annular elastic member 32 is elastically deformed by the body 31, thereby realizing rapid pressure relief and ensuring personnel safety.
[0048] Embodiment 3, refer to Figure 5 The difference between this embodiment and embodiment 1 is that it is suitable for severe chemical reactions: the air permeable gasket 3 is provided with a pressure relief groove 4, and the pressure relief groove 4 is in the shape of a cross; during the synthesis experiment, the pressure relief groove 4 is first in a closed state, and when the pressure in the reaction tube rises, the air permeable gasket 3 expands to drive the pressure relief groove 4 to open, so that the pressure is promptly discharged through the cross-shaped pressure relief groove 4, thereby relieving the risk of bottle explosion caused by excessive pressure. At the same time, the cross-shaped pressure relief groove 4 can effectively disperse the pressure impact, so that the air permeable gasket 3 can expand more uniformly when subjected to pressure, thereby further improving its pressure relief efficiency and safety.
[0049] The working process and implementation principle of the explosion-proof bottle cap in embodiment 3 are as follows: by providing the air permeable gasket 3 with a pressure relief groove 4 and setting the pressure relief groove 4 in the shape of a cross, the pressure is dispersed, so that the air permeable gasket 3 can expand uniformly, thereby further improving the pressure relief efficiency.
[0050] Embodiment 4, refer to Figure 6 The difference between this embodiment and embodiment 3 is that the pressure relief groove 4 is in the shape of a river; when the pressure in the reaction tube is too high, the river-shaped pressure relief groove 4 can effectively disperse the pressure on the air permeable gasket 3, so that the high-pressure gas can be quickly dispersed and discharged when passing through, thereby ensuring the rapid reduction of the pressure in the reaction tube and avoiding the phenomenon of reactant spraying, and further relieving the risk of bottle explosion caused by excessive pressure.
[0051] The working process and implementation principle of the explosion-proof bottle cap in embodiment 4 are as follows: by providing the air permeable gasket 3 with a pressure relief groove 4 and setting the pressure relief groove 4 in the shape of a river, it is ensured that the pressure in the reaction tube can be discharged, the phenomenon of reactant spraying is avoided, and the safety of the experiment is improved.
[0052] Embodiment 5, refer to Figure 7 The difference between this embodiment and embodiment 1 is that it is suitable for severe chemical reactions: the cap body 1 is provided with a notch 5, the notch 5 is inwardly inclined and arranged on the upper end surface of the cap body 1, and the notch 5 and the upper end surface of the cap body 1 form a gap for placing the air permeable gasket 3; during the synthesis experiment, the researcher first embeds the air permeable gasket 3 into the upper end surface of the cap body 1, applies a pressing force to the air permeable gasket 3 through the edge of the notch 5, so that the air permeable gasket 3 is tightly attached to the through hole 2, thereby ensuring the sealing property of the reaction tube and ensuring the smooth progress of the experiment.
[0053] The working process and implementation principle of the explosion-proof bottle cap in Embodiment 5 are as follows: the air permeable gasket 3 is embedded in the upper end face of the cap body 1 through the notch 5, which ensures the stability of the installation of the air permeable gasket 3 and also enables the air permeable gasket 3 to be more easily and quickly blown open by high-pressure gas when the pressure in the reaction tube abnormally increases, so as to realize timely pressure relief and ensure the safe performance of the experiment.
[0054] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
