Technical Field

[0001] The utility model belongs to the technical field related to krypton gas storage, and particularly relates to a self-sealing inflation device for a krypton gas storage tank. Background Art

[0002] Krypton gas is an important industrial gas, which is widely used in many fields such as semiconductor manufacturing, metal processing, lighting equipment, etc. In these applications, krypton gas usually needs to be stored and transported under specific pressure and temperature conditions, which requires that the krypton gas storage tank must have high safety and reliability.

[0003] Traditional krypton gas storage tanks often have some problems. When storing krypton gas, the sealing degree is relatively low. When pumping and discharging gas, it is easy to leak and cannot perform self-sealing treatment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self-sealing inflation device for a krypton gas storage tank to solve the problems of relatively low sealing degree when storing krypton gas, easy leakage when pumping and discharging gas, and inability to perform self-sealing treatment mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A self-sealing inflation device for a krypton gas storage tank, comprising

[0007] A krypton gas storage tank body and reinforcing ribs arranged on the outer surface of the krypton gas storage tank body, and a support frame is arranged below the krypton gas storage tank body;

[0008] One end of the krypton gas storage tank body is provided with a self-sealing inflation port, and a self-sealing component is inserted into the self-sealing inflation port;

[0009] A normally closed sealing cap is sleeved outside the self-sealing component.

[0010] Preferably, the self-sealing component includes a threaded air inlet pipe column and a conical rubber air inlet pipe. The threaded air inlet pipe column is screwed into the self-sealing inflation port through external threads, and one end of the threaded air inlet pipe column is connected with a conical rubber air inlet pipe, and the conical rubber air inlet pipe is inserted into the krypton gas storage tank body.

[0011] Preferably, the conical rubber air inlet pipe is a conical air inlet hole structure made of flexible rubber material. The diameter of the connection end of the conical rubber air inlet pipe and the threaded air inlet pipe column is larger than the diameter of the other end, and the small-diameter end of the conical rubber air inlet pipe is in a closed state without external force.

[0012] Preferably, the general length of the threaded intake pipe column is inserted into the interior of the self-sealing inflation port for connection, and the other half of the length is connected to the normally closed sealing cap. The normally closed sealing cap is sleeved on the other half of the length of the threaded intake pipe column and is screwed and sealed using threads.

[0013] Preferably, at the connection between the lower part of the krypton gas storage tank body and the support frame, mounting studs are provided, and mounting nuts are sleeved on the mounting studs. The krypton gas storage tank body is fixedly connected to the support frame through the sleeving of the mounting studs and the mounting nuts.

[0014] Preferably, mounting holes are provided at the bottom of the support frame, and the support frame is connected to external equipment through the mounting holes.

[0015] Preferably, there are two support frames in total, and both support frames are triangular structures, which are successively installed at both ends of the lower part of the krypton gas storage tank body.

[0016] Compared with the prior art, the present utility model provides a self-sealing inflation device for a krypton gas storage tank, having the following beneficial effects:

[0017] Enhanced tank strength: By providing reinforcing ribs on the outer surface of the krypton gas storage tank body, the overall strength of the tank body is significantly improved. This can not only resist the large pressure of the internal krypton gas and prevent the tank body from bursting due to excessive pressure, but also play a buffering role when the tank body is impacted externally, protecting the tank body from damage, thereby reducing the risk of krypton gas leakage;

[0018] Optimized support structure: The two triangular support frames provided below the krypton gas storage tank body provide stable and firm support. This structural design can not only bear the weight of the tank body, but also keep the tank body stable during handling or transportation, avoiding tipping or sliding;

[0019] High-efficiency sealing performance: The design of the self-sealing inflation port and the self-sealing component ensures the sealing performance of the krypton gas storage tank during the inflation and deflation processes. The elastic deformation mechanism of the conical rubber intake pipe can open and close the sealed port during inflation and deflation. Even during frequent injection and extraction operations, krypton gas leakage can be effectively avoided, and the presence of the normally closed sealing cap ensures the airtightness of the system in the non-operating state. This design effectively avoids krypton gas leakage during the inflation and deflation processes and improves the use safety;

[0020] Convenient operation experience: The setting of the self-sealing component simplifies the inflation and deflation operation process. The user only needs to screw the normally closed sealing cap and insert the external connector to start injecting gas. Similarly, when extracting krypton gas, only need to slowly insert the extraction pipe and open the sealed port. This design makes the operation more intuitive and convenient, reducing the operation difficulty and the possibility of errors;

[0021] Good generality and adaptability: The krypton gas storage tank and the self-sealing inflation device described in this technical solution have good generality and adaptability. It can be applied to krypton gas storage scenarios of different scales and uses to meet the needs of different users. At the same time, due to its simple design and convenient manufacturing, it has high economic efficiency and market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0031] A self-sealing inflation device for a krypton gas storage tank, comprising

[0032] The krypton gas storage tank 5 and the reinforcing ribs 1 provided on the outer surface of the krypton gas storage tank 5 are used. With the arrangement of the reinforcing ribs 1, the overall strength of the krypton gas storage tank 5 is higher. On the one hand, it avoids the excessive internal krypton gas pressure in the krypton gas storage tank 5, increasing the pressure on the tank body. The arrangement of the reinforcing ribs 1 can improve the compressive capacity of the tank body. Secondly, the reinforcing ribs 1 are plate-like structures vertically arranged on the surface of the tank body and have a certain buffering effect themselves. If an external object hits the tank body, it will first touch the reinforcing ribs. At this time, the reinforcing ribs 1 will deform to a certain extent when being hit, thereby buffering the impact force on the tank body and protecting the tank body from being damaged by external impact and causing krypton gas leakage. And a support frame 7 is arranged below the krypton gas storage tank 5; at the connection between the lower part of the krypton gas storage tank 5 and the support frame 7, an installation stud 9 is provided, and an installation nut 8 is sleeved on the installation stud 9. The krypton gas storage tank 5 is fixedly connected to the support frame 7 through the sleeving of the installation stud 9 and the installation nut 8. An installation hole 6 is provided at the bottom of the support frame 7, and the support frame 7 is connected to external equipment through the installation hole 6; there are two support frames 7 in total, and both support frames 7 are triangular structures, which are successively installed at both ends of the lower part of the krypton gas storage tank 5. The two triangular structures can fix the krypton gas storage tank 5 from both ends, making it more firm. The two support frames 7 arranged successively support the krypton gas storage tank 5, and then the equipment is fixed at the designated position by using the installation hole 6 below, and a bolt or other structure is inserted for limit installation.

[0033] In this technical solution, preferably

[0034] One end of the krypton gas storage tank 5 is provided with a self-sealing inflation port 2, and a self-sealing component is inserted inside the self-sealing inflation port 2; a normally closed sealing cap 4 is sleeved outside the self-sealing component; the self-sealing component includes a threaded inlet gas pipe column 3 and a tapered rubber inlet gas pipe 10. The threaded inlet gas pipe column 3 is screwed into the inside of the self-sealing inflation port 2 through external threads, and one end of the threaded inlet gas pipe column 3 is connected to the tapered rubber inlet gas pipe 10, and the tapered rubber inlet gas pipe 10 is inserted into the krypton gas storage tank 5; the tapered rubber inlet gas pipe 10 is a tapered air inlet hole structure made of flexible rubber material. The diameter of the connection end of the tapered rubber inlet gas pipe 10 and the threaded inlet gas pipe column 3 is larger than the diameter of the other end, and the small-diameter end of the tapered rubber inlet gas pipe 10 is in a closed state without external force; generally, half of the length of the threaded inlet gas pipe column 3 is inserted into the self-sealing inflation port 2 for connection, and the other half of the length is connected to the normally closed sealing cap 4. The normally closed sealing cap 4 is sleeved on the other half of the length of the threaded inlet gas pipe column 3 and is screwed and sealed by using threads.

[0035] Due to the arrangement of the self-sealing component, the sealing performance of the krypton gas storage tank body 5 is better. When krypton gas needs to be stored in the krypton gas storage tank body 5, the normally closed sealing cap 4 is first screwed open to expose one end of the threaded air inlet column 3. Since the interior of the threaded air inlet column 3 is hollow and connected to the conical rubber air inlet pipe 10, the external air injection interface is inserted into the threaded air inlet column 3 to start air injection. The external gas enters the conical rubber air inlet pipe 10 through the threaded air inlet column 3 and is subjected to the pressure generated by the entry of external krypton gas. At this time, the end of the small diameter of the conical rubber air inlet pipe 10 begins to elastically deform, and the sealed opening opens, and the external krypton gas enters the interior of the krypton gas storage tank body 5. After the air injection is completed, due to the lack of external gas force, the end of the small diameter of the conical rubber air inlet pipe 10 begins to elastically reset, and the opening is sealed again. In addition, since a large amount of krypton gas is stored in the krypton gas storage tank body 5, the internal pressure increases, and the greater pressure will act on the conical rubber The air intake pipe 10 is deformed and bent, and after bending, the sealing degree of the conical rubber air intake pipe 10 is stronger, which further avoids the leakage of krypton gas. The setting of the self-sealing component strengthens the sealing of the krypton gas storage tank body 5 during the storage process, and during use, when the normally closed sealing cap 4 is screwed open, due to the setting of the self-sealing component, the krypton gas inside the tank body will not leak, so that there will be no leakage when injecting krypton gas again or extracting krypton gas. When injecting, it is only necessary to insert the external joint into the interior of the threaded air intake pipe column 3 again. When extracting, it is necessary to slowly insert the external extraction pipe into the end of the small diameter of the conical rubber air intake pipe 10, and then stretch it open, insert it into the krypton gas storage tank body 5 for extraction, and due to the rubber elastic force of the end of the small diameter of the conical rubber air intake pipe 10, it will cling to the outer wall of the inserted pipe, thereby avoiding the leakage of krypton gas. After the extraction is completed, the pipe is extracted, and the end of the small diameter of the conical rubber air intake pipe 10 will be elastically sealed again, self-sealing.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
