Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage, and more specifically to a leak-proof chemical storage device. Background Art

[0002] In the chemical industry, safe storage and transportation of chemical gases are crucial. Gas cylinders, as a common storage and transportation device, are widely used in various industrial and laboratory environments. However, due to the special properties of gases and high-pressure storage conditions, gas cylinder leakage may cause serious safety risks and environmental pollution.

[0003] Most of the existing gas cylinders are only leak-proofed by gas valves. Once the internal seals of the gas valves are aged or damaged, the sealing will be reduced and leakage will occur. Moreover, such leakage cannot usually be discovered in time. If the gas is highly polluting, serious consequences will occur. Some gas cylinders are equipped with gas sensors or infrared detectors, but they can only serve as an alarm when gas leaks and cannot be stopped. In addition, the cost is high and it is inconvenient to put them into large-scale production.

[0004] Therefore, a leak-proof chemical storage device is proposed to address the above problems. Utility Model Content

This solution adds two other sealing measures on the basis of the gas valve. Through the multi-layer protection design, the sealing performance of the gas bottle can be effectively improved and the possibility of gas leakage can be reduced. The speaker setting can promptly sound an alarm when the gas leaks, and the spherical airbag can temporarily block the gas leakage, providing the user with valuable emergency time. The overall structure of the device is simple, the operation is convenient, and the cost is low. It is suitable for large-scale production and is conducive to improving economic benefits.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A leak-proof chemical storage device comprises a gas bottle, a gas valve is installed on the top of the gas bottle, a connecting ring is arranged on the outer side of the gas valve, the connecting ring is fixedly connected to the gas bottle, a sealing cover is threadedly connected to the connecting ring, and a monitoring component is arranged on the outer side of the connecting ring, the monitoring component comprises a mounting ring, an annular airbag is installed on the inner end of the mounting ring, and a connecting column is fixedly connected to the outer end of the mounting ring, and a spherical airbag is installed on the end of the connecting column away from the mounting ring.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution adds two other sealing measures on the basis of the gas valve. The first is to cover the gas valve with a sealing cover. If the gas valve leaks, the sealing cover can trap the gas inside to prevent gas leakage. The second is to form a closed space between the inner cavity of the mounting ring and the sealing cover through an annular air bag, which can avoid gas leakage caused by the sealing cover not being tightened. Through the multi-layer protection design, the sealing performance of the gas bottle can be effectively improved and the possibility of gas leakage can be reduced.

The expanded spherical airbag will trigger the speaker to sound an alarm, reminding the user to take timely remedial measures for the leakage. In the process, the spherical airbag can temporarily block the gas leakage, providing the user with valuable emergency time, thereby improving the practicality of the device.

[0035] In the chemical industry, safe storage and transportation of chemical gases are crucial. Gas cylinders, as a common storage and transportation device, are widely used in various industrial and laboratory environments. Most of the existing gas cylinders are only leak-proofed by gas valves. Once the internal seals of the gas valves are aged or damaged, the sealing will be reduced and cause leakage, and such leakage is usually not discovered in time. If the gas is highly polluting, it will cause serious consequences. Some gas cylinders are equipped with gas sensors or infrared detectors, but they can only serve as an alarm when gas leaks, and cannot be stopped. In addition, the cost is high, which is inconvenient for large-scale production.

[0036] In this solution, the user can inject chemical gas into the inner cavity of the gas bottle 1 through the gas valve 4. The gas valve 4 can be a ball valve, a butterfly valve or other types of valves. By rotating or pushing the operating rod of the valve, the opening and closing of the valve can be controlled to achieve gas injection or stop. The sealing parts used in the gas valve 4, such as O-rings or sealing gaskets, may age, harden or be damaged due to long-term use or improper storage conditions, resulting in reduced sealing and possible leakage. Therefore, this solution adds two other sealing measures on the basis of the gas valve 4. First, through the sealing cover 2 and the connecting ring 5, The threaded connection can cover the gas valve 4. If the gas valve 4 leaks, the gas can be trapped in it by the sealing cover 2 to prevent gas leakage. Secondly, the user can start the air pump 303 to expand the annular airbag 302, so that the outer end of the annular airbag 302 is tightly abutted against the outer end of the sealing cover 2, thereby achieving a seal between the inner cavity of the mounting ring 301 and the sealing cover 2. Such a setting can avoid gas leakage caused by the sealing cover 2 not being tightened. Through the setting of the sealing cover 2 and the annular airbag 302, the sealing performance of the gas bottle 1 can be effectively improved, and the possibility of gas leakage can be reduced.

[0037] See also Figure 4The outer end of the mounting ring 301 is fixedly connected to a bracket 304, a button 308 is installed at the inner end of the bracket 304, the button 308 and the spherical airbag 306 are at the same horizontal position, and a speaker 307 is installed at the outer end of the bracket 304, and the speaker 307 and the button 308 are electrically connected.

[0038] If gas leaks into the inner cavity of the mounting ring 301, as the gas spreads, the gas will enter the inner cavity of the spherical airbag 306 through the connecting column 305, thereby causing the spherical airbag 306 to expand. The expanded spherical airbag 306 will touch the button 308 and squeeze it. The triggered button 308 will control the speaker 307 to sound an alarm, reminding the user to make timely remedial measures for the leakage. In this process, the spherical airbag 306 can temporarily block the gas leakage, providing the user with precious emergency time. The overall structure of the device is simple, the cost is low, and it is suitable for large-scale production.

[0039] Working principle:

[0040] During use, the user can inject chemical gas into the inner cavity of the gas bottle 1 through the gas valve 4. After the injection is completed and the gas valve 4 is closed, the user can cover the gas valve 4 through the threaded connection between the sealing cover 2 and the connecting ring 5, and then start the air pump 303 to expand the annular airbag 302, so that the outer end of the annular airbag 302 is tightly abutted against the outer end of the sealing cover 2, so as to achieve the seal between the inner cavity of the mounting ring 301 and the sealing cover 2. With this arrangement, the gas valve 4 can be covered by the sealing cover 2. If the gas valve 4 leaks, the gas can be trapped in it through the sealing cover 2 to block the gas. The annular airbag 302 can prevent gas leakage caused by the sealing cover 2 not being tightened. If gas leaks into the inner cavity of the mounting ring 301, as the gas spreads, the gas will enter the inner cavity of the spherical airbag 306 through the connecting column 305, thereby expanding the spherical airbag 306. The expanded spherical airbag 306 will touch the button 308 and squeeze it. The triggered button 308 will control the speaker 307 to sound an alarm, reminding the user to make remedial measures for the leakage in time. In the process, the spherical airbag 306 can temporarily block the gas leakage.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
