Description

Technical Field

[0001] This utility model relates to the field of sealing structures, and in particular to an argon gas combination pipe sealing structure. Background Technology

[0002] In modern industrial systems, argon, with its stable chemical inertness, has become an indispensable process gas in key areas such as metal welding, semiconductor manufacturing, and heat treatment. In these applications, argon delivery relies on combined pipe systems to accurately and safely deliver argon to designated process locations, which places stringent requirements on the sealing performance of the combined pipes.

[0003] Traditional argon gas combination pipe sealing methods have many drawbacks. Current sealing methods mainly use a single sealing ring for sealing. When faced with complex and ever-changing working conditions, it is difficult to guarantee the sealing effect. Under long-term gas pressure impact, the wrapped sealing tape will loosen and fall off, making it impossible to maintain a stable sealing state.

[0004] Therefore, we propose an argon gas combined pipe sealing structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Traditional argon gas combination pipe sealing methods have many drawbacks. Current sealing methods mainly use a single sealing ring, which is difficult to guarantee the sealing effect when facing complex and ever-changing working conditions. Under long-term gas pressure impact, the wrapped sealing tape will loosen and fall off, making it impossible to maintain a stable sealing state.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An argon gas combined pipe sealing structure includes a first combined pipe and a second combined pipe. A first sealing connector is provided on the outer side of the first combined pipe, and a second sealing connector is provided on the outer side of the second combined pipe. The first and second sealing connectors are interlocked to form a multi-layer seal. Flange connectors are installed on the outer sides of both the first and second sealing connectors. The two flange connectors are used to fix the first and second sealing connectors and reserve installation positions. A protective seal detection component is also provided between the two flange connectors. The protective seal detection component is used to protect the connection between the two flange connectors, the connection between the first and second sealing connectors, and the connection between the first and second combined pipes and to monitor for leakage.

[0008] As a preferred embodiment of this utility model, the first combined pipe has a pipe body connecting groove inside, and the second combined pipe has a pipe body connecting block on its inner side. The pipe body connecting block is inserted into the pipe body connecting groove to form a first seal.

[0009] As a preferred embodiment of the present invention, the first sealing connector includes a first connector body, a first sealing insertion groove is provided inside the first connector body near the inner side, a second sealing insertion groove is provided inside the first connector body near the outer side, and sealing gaskets are provided on both sides of the inner side wall of the second sealing insertion groove.

[0010] As a preferred embodiment of the present invention, the second sealing connector includes a second connector body, a first sealing plug-in block is provided on the inner side of the second connector body near the bottom, and a second sealing plug-in block is provided on the inner side of the second connector body near the top.

[0011] As a preferred embodiment of this utility model, the flange connector includes a flange body, the flange body has an installation sealing groove inside, the installation sealing groove is provided with a plurality of fixing bodies, and each of the plurality of fixing bodies is provided with a sealing bolt inside.

[0012] As a preferred embodiment of this utility model, the protective sealing detection assembly includes an annular plug-in protective body, an installation detection cavity is provided inside the annular plug-in protective body, a fitting groove is provided on the outer side of the installation detection cavity, and a pressure sensor is provided inside the installation detection cavity.

[0013] As a preferred embodiment of this utility model, the first sealing plug is inserted into the first sealing plug groove, the second sealing plug is inserted into the second sealing plug groove, and the two sealing gaskets are used to fit and compress the second sealing plug, thereby enhancing the seal.

[0014] In a preferred embodiment of this utility model, the two flange connectors are connected by sealing bolts. The fixing body is used to install the sealing bolts, the mounting sealing groove is used to insert the annular plug-in protective body, the fitting groove is used to fit the fixing body, and the annular plug-in protective body fits the inner wall of the mounting sealing groove. The annular plug-in protective body and the flange body are connected by bolts, thereby forming a seal between them. The air pressure sensor is used to detect the air pressure inside the annular plug-in protective body, thereby protecting the connection between the two flange connectors, the connection between the first sealing connector and the second sealing connector, and the connection between the first combined pipe and the second combined pipe, and monitoring for air leakage.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention abandons the traditional single-ring sealing method and innovatively adopts a multi-layer sealing structure in which the first and second sealing connectors interlock. Through the precise fit between the first sealing connector and the first sealing groove, and between the second sealing connector and the second sealing groove, as well as the close compression of the sealing gasket against the second sealing connector, a multi-layered, all-around sealing defense is formed. This design greatly improves the reliability of the seal, effectively prevents argon gas leakage, and compared to traditional single-ring sealing methods, it can better adapt to complex and changing working conditions, maintaining a stable sealing state even under long-term gas pressure impact.

[0017] The reinforced connection sealing involves the insertion of the pipe body connecting groove of the first combined pipe and the pipe body connecting block of the second combined pipe into each other, forming the first seal and laying the foundation for the entire sealing structure. In addition, the synergistic effect of the multi-layer sealing connectors provides multiple reinforced seals at the connection between the first and second combined pipes, effectively solving the problem of weak sealing at pipe connections in traditional sealing methods and ensuring that argon gas will not leak from the connection during transportation.

[0018] With reliable protection and real-time monitoring functions, the annular plug-in protective body not only provides physical protection for the connection of the two flange connectors, the connection of the first sealing connector and the second sealing connector, and the connection of the first combined pipe and the second combined pipe, preventing external impurities from affecting the sealing effect, but also has a built-in pressure sensor that can monitor the pressure changes inside the annular plug-in protective body in real time. Once an argon leak occurs, the pressure sensor can quickly detect it and send a signal, making it easy for staff to discover and deal with the problem in a timely manner, effectively avoiding increased production costs and safety risks caused by argon leaks.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model are given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0033] like Figure 1-9 As shown, this utility model provides a technical solution: In this utility model, the traditional single sealing ring sealing method is abandoned, and a multi-layer sealing structure in which the first sealing connector and the second sealing connector are interlocked is innovatively adopted. The traditional single sealing ring sealing method relies on a single sealing element to block gas leakage. Its sealing effect is greatly affected by the sealing ring material, installation process and working conditions. In complex industrial environments, such as high temperature, high pressure and high vibration, the single sealing ring is prone to aging, deformation or wear, which leads to sealing failure.

[0034] This structure, through the precise fit between the first sealing plug 601 and the first sealing plug groove 201, the second sealing plug 602 and the second sealing plug groove 202, and the close compression of the sealing gasket 203 against the second sealing plug 602, forms a multi-layered, all-round sealing barrier. The tight fit between the first sealing plug 601 and the first sealing plug groove 201, using the interference or transition fit between the two, prevents gas from leaking from the inner gap. The second sealing plug 602 and the second sealing plug groove 202 further strengthen the seal. The presence of the sealing gasket 203 increases the contact area and friction. When the second sealing plug 602 is inserted into the second sealing plug groove 202, the sealing gasket 203 is compressed and deformed, filling any possible tiny gaps, thus forming another effective sealing barrier.

[0035] This design greatly improves the reliability of the seal and effectively prevents argon leakage. In actual operation, argon will generate a certain pressure when it flows in the pipeline. The multi-layer sealing structure can withstand and disperse the pressure in turn. Compared with the traditional single sealing method, it can better adapt to complex and changing working conditions. Even under long-term gas pressure impact, the various sealing links in the multi-layer sealing structure cooperate with each other to always maintain a stable sealing state.

[0036] During installation, the first sealing plug 601 on the second sealing connector is accurately inserted into the first sealing plug groove 201 of the first sealing connector. Then, the second sealing plug 602 is inserted into the second sealing plug groove 202. The sealing gasket 203 is compressed during insertion and begins to perform a sealing function. After installation, when argon gas flows in the pipeline and generates pressure, the pressure first acts on the sealing point between the innermost first sealing plug 601 and the first sealing plug groove 201. This point blocks part of the pressure, and the remaining pressure continues to be transmitted outward. The sealing structure composed of the second sealing plug 602, the second sealing plug groove 202, and the sealing gasket 203 further blocks the pressure, thereby achieving effective sealing of the argon gas.

[0037] The reinforced connection sealing is achieved by interlocking the pipe body connecting groove 101 of the first combined pipe 1 with the pipe body connecting block 501 of the second combined pipe 5 to form the first seal, which lays the foundation for the entire sealing structure. The design of the pipe body connecting groove 101 and the pipe body connecting block 501 utilizes the interlocking principle in mechanical structures. By tightly inserting the pipe body connecting block 501 into the pipe body connecting groove 101, a tight contact is formed between the two, reducing the gap at the pipe connection and fundamentally reducing the possibility of argon leakage.

[0038] In addition, the multi-layer sealing connectors work together to reinforce the seal at the connection between the first combined pipe 1 and the second combined pipe 5. The multi-layer sealing connectors further enhance the seal on the outside of the pipe connection. When argon gas attempts to leak from the pipe connection, it will first encounter the first barrier formed by the pipe body connecting groove 101 and the pipe body connecting block 501, which reduces the leakage. The remaining small amount of leaked gas will be blocked by the multi-layer sealing connectors during its outward diffusion, further ensuring the sealing effect.

[0039] This design effectively solves the problem of weak sealing at pipe joints in traditional sealing methods, ensuring that argon gas will not leak from the joints during transportation. Traditional sealing methods often only focus on sealing the outside of the pipe, while neglecting the gap problem inside the pipe joint. This design forms a complete sealing system by simultaneously sealing the inside and outside of the pipe, which greatly improves the sealing performance of the pipe joint.

[0040] When installing the first combined pipe 1 and the second combined pipe 5, first insert the pipe body connecting block 501 of the second combined pipe 5 into the pipe body connecting groove 101 of the first combined pipe 1 to complete the first sealing installation. Then install the first sealing connector and the second sealing connector so that they are interlocked. During the argon gas transportation process, the argon gas pressure acts on the pipe connection. The pipe body connecting groove 101 and the pipe body connecting block 501 first prevent argon gas from leaking from the inside. If a small amount of argon gas bypasses this point, the multi-layer sealing connector will continue to block it, thereby ensuring the seal at the connection.

[0041] With reliable protection and real-time monitoring functions, the annular plug-in protective body 4 not only provides physical protection for the connection of the two flange connectors, the connection of the first sealing connector and the second sealing connector, and the connection of the first combined pipe 1 and the second combined pipe 5, preventing external impurities from intruding and affecting the sealing effect, but also adopts a tight-fitting installation method, surrounding the outside of each connection to form a closed protective space. External impurities such as dust and particles cannot enter the sealing connection after contacting the annular plug-in protective body 4, avoiding wear and corrosion of the seals by impurities, thereby extending the service life of the sealing structure.

[0042] The built-in pressure sensor 403 can monitor the pressure changes inside the annular plug-in protective body 4 in real time. Once an argon leak occurs, the pressure sensor 403 can quickly detect it and send a signal. The principle is based on the effect of gas pressure changes on the sensor element. When argon leaks into the annular plug-in protective body 4, the internal pressure will change. The sensitive element in the pressure sensor 403 will generate a corresponding electrical signal change due to the pressure change. Through circuit transmission and processing, this change is converted into a recognizable signal output, which makes it easier for staff to detect and deal with the problem in a timely manner.

[0043] The fixing body 302 is used to install the sealing bolt 303, the mounting sealing groove 301 is used to insert the annular insertion protective body 4, the fitting groove 402 is used to fit the fixing body 302, the annular insertion protective body 4 fits the inner wall of the mounting sealing groove 301, and the annular insertion protective body 4 and the flange body 3 are connected by bolts, thereby forming a seal between the two.

[0044] This design effectively avoids increased production costs and safety risks caused by argon gas leaks. Argon gas leaks not only waste gas resources and increase production costs, but may also cause safety accidents in certain environments. Through real-time monitoring and timely alarms, staff can quickly take measures, such as repairing leak points and replacing seals, to prevent the leak from worsening.

[0045] After the entire sealing structure is installed, the annular plug-in protective body 4 is installed between the two flange connectors, so that it fits tightly against the inner wall of the sealing groove 301, and is fixed to the flange body 3 with bolts to form a sealed space. The pressure sensor 403 starts to monitor the pressure inside the annular plug-in protective body 4 in real time. If a leak occurs at a certain connection during the argon gas transportation process, argon gas enters the annular plug-in protective body 4, causing a change in internal pressure. After the pressure sensor 403 detects the change, it sends a signal. After receiving the signal, the staff will take appropriate action.

[0046] Work process summary

[0047] Pipe connection: The pipe body connecting block 501 of the second combined pipe 5 is precisely inserted into the pipe body connecting groove 101 of the first combined pipe 1. By using the mechanical insertion and mating principle, a tight contact is formed to form the first seal, reducing the internal gap at the pipe connection and reducing the risk of argon gas leakage.

[0048] Sealing connector installation: The first sealing plug 601 on the second sealing connector is accurately embedded into the first sealing plug groove 201 of the first sealing connector, and then the second sealing plug 602 is inserted into the second sealing plug groove 202. During this process, the sealing gasket 203 is compressed and deformed, filling the tiny gaps and building a multi-layer sealing defense line, which greatly improves the sealing reliability.

[0049] Protective body installation: Install the annular plug-in protective body 4 between the two flange connectors, ensuring it fits tightly against the inner wall of the sealing groove 301. Secure it to the flange body 3 with bolts to form a closed protective space, preventing external impurities from intruding and affecting the sealing effect.

[0050] Sealing function: Argon gas flows in the pipeline and generates pressure. The pressure first acts on the innermost sealing point formed by the first sealing plug 601 and the first sealing plug groove 201, blocking part of the pressure. The remaining pressure is transmitted outward and blocked by the sealing structure formed by the second sealing plug 602, the second sealing plug groove 202 and the sealing gasket 203. At the same time, the pipe body connecting groove 101 and the pipe body connecting block 501 continuously prevent argon gas from leaking from the inside of the pipeline connection. The multi-layer sealing connection works together to ensure that argon gas will not leak from the connection during transportation.

[0051] The pressure sensor 403 monitors the pressure inside the annular plug-in protective body 4 in real time. If a leak occurs at a certain connection during argon gas delivery, argon gas enters the annular plug-in protective body 4, causing a change in internal pressure. The pressure sensor 403 quickly senses the change and sends a signal.

[0052] After receiving the signal from the pressure sensor 403, the staff immediately inspected the sealing structure to determine the location and cause of the leak. For specific problems, they took measures such as repairing the leak point and replacing the seal to prevent the leak from worsening and ensure the continuous normal operation of the sealing structure.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
