Description
Technical Field
[0001] The utility model relates to the technical field of chemical reaction containers, in particular to a safe reaction device suitable for trace reactions. Background Art
[0002] When conducting chemical reaction research experiments, it is generally necessary to use a certain reaction device to complete them. According to different types of chemical reactions, people have designed many types of reaction devices. When conducting different chemical experiments, the most suitable reaction device can be selected to ensure the smooth progress of related chemical reactions. At present, the reaction devices used for trace reactions are mostly simple in function and generally do not have the function of controlling pressure. Trace reactions, as the name suggests, refer to chemical reactions with very small amounts of reactants. Although such reactions are small in amount, their importance cannot be ignored. In scientific research, trace reactions are often used for preliminary analysis of samples, synthesis of new compounds, etc. However, due to the small amount of reactants, the control of reaction conditions becomes particularly important, especially some reactions need to be carried out in a closed environment. In the prior art, when performing certain trace reactions, the most commonly used reaction device is just an ordinary reaction tube (such as a test tube). When using an ordinary reaction tube for trace reactions, since the ordinary reaction tube does not have a pressure regulation function, it is easy to cause dangerous phenomena such as explosion of the reaction tube during use. These phenomena will not only bring danger to the experimenters, but also affect the experimental results, and may even cause the experiment to fail. Therefore, designing a reaction device that can meet trace reactions and has pressure regulation function is of great significance for scientific research. Utility Model Content
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and to provide a safe reaction device suitable for trace reactions, which has a simple structure and is easy to adjust and use.
[0004] The technical scheme of the utility model is: a safe reaction device suitable for trace reactions, comprising a reaction tube and a tube plug, wherein the tube plug is installed at the tube mouth of the reaction tube, and a pressure relief valve is integrally arranged on the tube plug. After the tube plug is installed, when the pressure in the reaction tube exceeds a certain range, the pressure relief valve automatically opens to adjust the pressure in the reaction tube.
[0005] Furthermore, a first thread is provided at the tube mouth of the reaction tube, and a second thread is provided on the tube plug. The first thread and the second thread cooperate with each other, so that when the tube plug is installed on the reaction tube, the inner cavity of the reaction tube forms a closed space.
[0006] Furthermore, a branch pipe is provided on the side wall of the reaction tube, the branch pipe is connected to the inner cavity of the reaction tube, and a switch is provided on the branch pipe, and the switch is used to control the connection state of the branch pipe with the outside world. When the switch is turned on, the reaction tube is connected to the outside world. Conversely, when the switch is closed, the inner cavity of the reaction tube is isolated from the outside world to form a closed system.
[0007] Furthermore, the pipe plug and the pressure relief valve may be detachably connected to facilitate maintenance and installation.
[0008] Furthermore, there are two pressure relief valves, and the exhaust directions of the two pressure relief valves are opposite, so that no matter whether the gas pressure in the reaction tube is too low or too high, the pressure in the tube can be adjusted through the pressure relief valve with the corresponding exhaust direction.
[0009] Furthermore, the pressure relief valve can directly adopt a two-way pressure relief valve, so that the air pressure in the pipe can be regulated by only one pressure relief valve.
[0010] Furthermore, the reaction tube is cylindrical or spherical.
[0011] Furthermore, the reaction tube is made of any one of glass, plastic or metal.
[0012] Furthermore, there are multiple branch pipes, and at least one branch pipe has a pressure observation mechanism at its external port, and the user can judge the pressure inside the reaction tube by the state of the pressure observation mechanism. The pressure observation mechanism can be a balloon, and the user can judge the pressure inside the reaction tube by observing the volume of the balloon.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the safety reaction device in the present application is equipped with a pressure relief valve on the pipe plug, which can adjust the pressure according to the pressure required for the reaction and the air pressure that the reaction tube can withstand. The pressure relief valve can achieve two-way pressure relief, that is, when the pressure in the reaction tube is within the set safety range, the pressure relief valve does not work; once the pressure exceeds the set value (whether the pressure is too high or too low), the pressure relief valve will automatically start to adjust the pressure, control the pressure in the reaction tube within a safe range, ensure the smooth completion of the trace reaction, and avoid the risk of the reaction tube bursting; at the same time, the entire safety reaction device in the present application is small in size and easy to operate.

[0017] The present invention will be further described in detail below in conjunction with specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention.
[0018] Example 1
[0019] like Figure 1 As shown, this embodiment is a safe reaction device suitable for micro-reaction, including a reaction tube 1 and a tube plug 2, the tube plug 2 is installed at the tube mouth of the reaction tube 1, and a pressure relief valve 3 is integrated on the tube plug 2. After the tube plug 2 is installed, when the pressure in the reaction tube 1 exceeds a certain range, the pressure relief valve 3 automatically opens to adjust the pressure in the reaction tube 1. A first thread is provided at the inner wall of the tube mouth of the reaction tube 1, and a second thread is provided on the outer surface of the tube plug 2. The first thread is an external thread, and the second thread is an internal thread. The first thread and the second thread cooperate with each other, so that when the tube plug 2 is installed on the reaction tube 1, the inner cavity of the reaction tube 1 forms a closed space. In this embodiment, the reaction tube 1 is cylindrical, and the reaction tube is made of glass.
[0020] When the reaction device in this embodiment is in use, the reactants can be placed in the reaction tube, and then the tube plug is installed. Then, the reaction tube can be heated and other treatments can be performed to allow the reactants to undergo a chemical reaction. If the pressure in the tube exceeds the preset value of the pressure relief valve 3 during the chemical reaction, the pressure relief valve 3 will automatically open to allow part of the gas inside the reaction tube 1 to be discharged through the pressure relief valve 3, thereby ensuring that the gas pressure inside the reaction tube 1 is stable and preventing the reaction tube 1 from bursting.
[0021] Example 2
[0022] like Figure 2 As shown, the difference between the safety reaction device in this embodiment and the embodiment 1 is that: in this embodiment, a branch pipe 4 is also provided on the side wall of the reaction tube 1, and the branch pipe 4 is connected to the inner cavity of the reaction tube 1, and a switch 5 is provided on the branch pipe 4, and the switch 5 can be used to control the connection state between the branch pipe 4 and the outside world. When the switch 5 is turned on, the reaction tube 1 is connected to the outside world, and vice versa, when the switch 5 is closed, the inner cavity of the reaction tube 1 is isolated from the outside world to form a closed system. The advantage of the reaction device in this embodiment compared with the embodiment 1 is that: using the reaction device in this embodiment, in addition to automatically adjusting the pressure in the tube through the pressure relief valve 3, the user can also manually adjust the pressure in the reaction tube 1 by opening or closing the switch 5 on the branch pipe 4. In addition, the branch pipe can also be used to add reaction materials, that is, when the switch is turned on, the reaction materials can be sent from the branch pipe to the reaction tube.
[0023] In some other embodiments, the reaction tube 1 may also be conical or spherical, two pressure relief valves 3 may be provided, and the exhaust directions of the two pressure relief valves 3 are opposite, or a two-way pressure relief valve 3 may be used, so that no matter whether the air pressure in the reaction tube 1 is too low or too high, the pressure in the tube can be adjusted by the pressure relief valve 3, and there are multiple branch pipes, at least one of which is connected to a balloon, so that the user can judge the pressure situation inside the reaction tube more intuitively according to the volume of the balloon.
[0024] The above are only some embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have combinations and modifications of the aforementioned technical features. Without departing from the spirit and scope of the present invention, those skilled in the art may improve, modify, or replace the present invention with equivalents, or apply the structure or method of the present invention to other fields to achieve the same effect, which all fall within the scope of protection of the present invention.
