[0032] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0033] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] Please see Figure 1-8Traditional butt joints, when connecting to a water distribution system, use threaded fixing to ensure the stability of the joint. However, threaded fixing is not convenient for disassembly and replacement of pipes, and there are no corresponding fixing measures at the pipe joint. Under high water pressure, gaps can easily appear, causing water leakage. Based on this, this embodiment provides a possible implementation method, specifically a secondary water distribution pipeline connection device, including a quick connector 1 for connecting pipes. One end of the quick connector 1 is provided with an anti-detachment component 2, which is used to assist in the stability of the pipe connection.

[0035] The quick connector 1 has an inlet 12 and an outlet 15 at its two ends, and the anti-detachment component 2 is located at the outlet 15.

[0036] The anti-detachment component 2 includes a base 21, one end of which is provided with a plug-in flange 22, which is adapted to the water outlet 15;

[0037] One or more fastening plates 24 are provided at the other end of the base 21. A buffer area 26 is maintained between every two fastening plates 24. The fastening plates 24 are arranged in a ring array to assist in fastening the pipe with the water outlet 15.

[0038] As the core component of the entire connection device, quick connector 1 is made of high-purity stainless steel (such as 316L stainless steel). This material is corrosion-resistant and does not release contaminants, meeting the cleanliness requirements of semiconductor production. The inner diameters of the inlet 12 and outlet 15 of quick connector 1 are precisely designed according to the actual pipe diameter being connected, generally with a certain tolerance range to ensure good compatibility. The inner walls of the inlet 12 and outlet 15 are finely polished, achieving an extremely low surface roughness, which reduces water flow resistance and the possibility of particulate matter adhesion.

[0039] The base 21 is also made of the same high-purity stainless steel as the quick connector 1 to ensure overall corrosion resistance and cleanliness. The outer diameter of the base 21 is slightly larger than the outer diameter of the outlet 15 of the quick connector 1, facilitating installation and positioning. The height of the insertion flange 22 is generally between 10-20mm, and the thickness is between 3-5mm. Its outer surface is equipped with a sealing rubber ring made of EPDM (ethylene propylene diene monomer rubber), which has good elasticity and chemical corrosion resistance, effectively preventing leakage.

[0040] The number of fastening plates 24 is usually determined based on the size of the pipe and the required tightening force, generally 3-6. The fastening plates 24 are made of thin stainless steel sheets with a certain degree of elasticity, with a thickness between 1-2 mm. The inner surface of each fastening plate 24 undergoes special treatment, such as knurling or frosting, to increase the friction with the pipe surface.

[0041] The buffer area 26 is designed to be 5-10mm wide, which ensures that the fastening plate 24 has enough deformation space when under force, so as to fasten the pipe without damaging the pipe due to excessive compression.

[0042] Installation process:

[0043] First, connect the inlet 12 of quick connector 1 to the main water supply pipeline that has been introduced into the workshop. A clamp connection can be used. Place the clamp on the connection between the inlet 12 of quick connector 1 and the main water supply pipeline, and then use a wrench to tighten the clamp bolts to ensure a tight connection and good seal.

[0044] Next, insert the insertion flange 22 of the anti-detachment component 2 into the outlet 15 of the quick connector 1. During insertion, ensure that the sealing rubber ring is correctly installed and free from twisting to guarantee a good seal.

[0045] Finally, insert the pipe that needs to be connected to the customer's equipment between the fastening plates 24 of the anti-detachment component 2. During insertion, due to the elasticity of the fastening plates 24, they will naturally open and tightly hold the pipe. The fastening plates 24 can be better fitted to the pipe surface by gently rotating the pipe, further enhancing the fastening effect.

[0046] Primarily used in cleanrooms for semiconductor manufacturing, this secondary water distribution pipeline connection device can be widely applied to various equipment connection scenarios requiring secondary water distribution. For example, in the cooling system of lithography equipment, ultrapure water needs to be accurately and stably delivered to the equipment. This connection device ensures the stability and sealing of the pipeline connection, preventing equipment failure and production interruptions due to leaks or loose connections. Similarly, in the water supply system of cleaning equipment, it ensures the smooth delivery of high-purity water, preventing impurities from entering the equipment and affecting the cleaning effect.

[0047] Compared to the existing quick connector 1, the anti-detachment component 2 provides additional fastening force for the pipe connection. In particular, the fastening plates 24 are arranged in a ring array, which can evenly grip the pipe and effectively prevent the pipe from loosening and falling off under the impact of water flow or vibration, thus ensuring the stable operation of the secondary water distribution system.

[0048] The use of quick-connect coupling 1 and specially designed anti-loosening component 2 makes installation and disassembly much simpler and faster compared to traditional threaded fixing methods. This significantly saves time and labor costs, and improves work efficiency when replacing pipes or performing equipment maintenance.

[0049] The anti-detachment component 2 has a mating flange 22 that matches the outlet 15 and is equipped with a sealing rubber ring to effectively prevent leakage. Even under high water pressure, it can ensure the sealing of the pipe joint, avoiding water waste and pollution of the production environment.

[0050] The design of the quick connector 1's inlet 12, outlet 15, and anti-detachment component 2 can be customized according to different pipe diameters and connection requirements, and has strong versatility and adaptability, which can meet the diverse secondary water distribution needs in semiconductor production.

[0051] The entire connection device is made of high-purity stainless steel and clean-grade sealing materials, which can effectively prevent the introduction of particulate matter or contaminants, meet the strict requirements of semiconductor production for a high-cleanliness environment, and ensure the quality and performance stability of the product.

[0052] A positioning ring 25 is provided on the inner side of the base 21 near the insertion flange 22. The middle of the positioning ring 25 has an insertion channel 23, which is used to position the base 21 in conjunction with the water outlet 15.

[0053] A fastening ring 29 is provided at one end of the base 21 near the fastening plate 24, and the fastener is adapted to the outer side of the fastening plate 24.

[0054] The fastening plate 24 has a rough surface 27 on the side near the outlet 15, and the rough surface 27 is in contact with the outside of the pipe.

[0055] Each pair of fastening plates 24 has a receiving cavity 211 on the side that is close to each other, and a rotating shaft 210 is provided inside the receiving cavity 211.

[0056] An elastic cover 28 is wound around the outside of the rotating shaft 210 to cover the buffer area 26 between each pair of fasteners 24.

[0057] The positioning ring 25 and the base 21 are integrally molded and are also made of high-purity stainless steel to ensure overall corrosion resistance and cleanliness. The tolerance between its inner diameter and the outer diameter of the quick connector 1 outlet 15 is controlled within ±0.1mm to ensure a tight fit. The inner wall of the insertion channel 23 is finely polished to a surface roughness of Ra0.4μm or less to reduce friction with the outlet 15 and facilitate installation and disassembly.

[0058] Installation process: When installing the anti-detachment component 2 to the outlet 15 of the quick connector 1, first align the positioning ring 25 with the outlet 15. Since the insertion channel 23 in the middle of the positioning ring 25 is compatible with the outlet 15, you only need to push the base 21 gently to allow the insertion flange 22 to be smoothly inserted into the groove of the fastening connector 14 at the outlet 15. At the same time, the positioning ring 25 can ensure that the base 21 and the outlet 15 are precisely aligned to avoid misalignment during installation.

[0059] The inner diameter of the fastening ring 29 is slightly smaller than the outer diameter formed by the fastening plate 24 in its natural state. This allows the fastening ring 29 to exert a certain contractile force on the fastening plate 24 after installation, enhancing the tightening effect on the pipeline. The outer side of the fastening ring 29 is provided with anti-slip textures for easy manual tightening or loosening by operators.

[0060] Installation process: After the pipe is inserted between the fastening plates 24, the fastening ring 29 is placed on the outside of the fastening plates 24. The operator can manually rotate the fastening ring 29 to move it downwards along the outside of the fastening plates 24 until the fastening ring 29 is tightly fitted to the fastening plates 24. At this time, the fastening plates 24 will further tighten the pipe, achieving a more reliable connection.

[0061] The roughened surface 27 is formed through a special surface treatment process, such as electrical discharge machining or sandblasting. The surface roughness of the roughened surface 27 is controlled between Ra3.2 and Ra6.3 μm, which ensures sufficient friction with the outside of the pipe without scratching the pipe surface. The roughened surface 27 covers most of the area of ​​the fastening plate 24 near the outlet 15, generally accounting for 70%-80% of the area of ​​that side.

[0062] Working principle: When the pipe is inserted between the fastening plates 24, the rough surface 27 fits tightly against the outside of the pipe. Under conditions such as water flow impact or vibration, the rough surface 27 can increase the friction between the fastening plates 24 and the pipe, preventing the pipe from sliding relative to the fastening plates 24, thereby improving the stability of the connection.

[0063] The receiving cavity 211 is formed on the side where each pair of fastening plates 24 are close to each other. It is rectangular in shape, 5-8 mm deep, and its width matches the thickness of the elastic cover 28. The rotating shaft 210 is mounted inside the receiving cavity 211 and is made of stainless steel with a polished surface to reduce friction with the elastic cover 28. The elastic cover 28 is made of a rubber material with good elasticity and chemical resistance, such as EPDM rubber, and has a thickness of 1-2 mm.

[0064] Working process: During pipe installation, as the pipe is inserted between the fastening plates 24, the fastening plates 24 open, and the elastic cover 28 unfolds with the rotation of the rotating shaft 210, covering the buffer area 26 between every two fastening plates 24. After the pipe is installed, the elastic cover 28 can prevent impurities, dust, etc. from entering the buffer area 26, and also plays a certain role in sealing, reducing the risk of water leakage.

[0065] Compared to the existing quick connector 1, the positioning ring 25 ensures that the anti-detachment component 2 is precisely aligned when installed onto the outlet 15 of the quick connector 1, guaranteeing the accuracy and stability of the connection. This helps improve installation efficiency, avoids problems such as poor sealing or weak connection caused by installation misalignment, and ensures the normal operation of the secondary water distribution pipeline system.

[0066] The combined use of the fastening ring 29 and the fastening plate 24 further enhances the tightening force on the pipeline. Through the contraction of the fastening ring 29, the fastening plate 24 can more tightly grip the pipeline, effectively preventing the pipeline from loosening and falling off under high-pressure water flow or vibration environment, thus improving the reliability and safety of the connection.

[0067] Meanwhile, the design of the rough surface 27 increases the friction between the fastening plate 24 and the pipe, which can better resist the tendency of the pipe to slide. In semiconductor manufacturing, when the water flow pressure is unstable or the equipment vibrates, it can ensure the stability of the pipe connection, reduce the risk of water leakage and contamination caused by pipe loosening, and ensure the continuity of the production process and product quality.

[0068] Furthermore, the combination of the receiving cavity 211 and the elastic cover 28 provides protection and sealing for the buffer area 26. The elastic cover 28 prevents impurities from entering the buffer area 26, avoiding the accumulation of impurities that could affect the elasticity and fastening effect of the fastening plate 24. At the same time, it also provides a certain degree of sealing, reducing the possibility of water leakage and maintaining the cleanliness of the secondary water distribution pipeline system, which meets the stringent requirements of semiconductor manufacturing for a high-cleanliness environment.

[0069] The quick connector 1 includes a body 13, a grip 11 is provided on the outer side of the body 13, and a fastening fastener 14 is provided at one end of the grip 11, with the fastener located near the end of the outlet 15.

[0070] A threaded groove is provided on one side of the fastening connector 14, and the threaded groove is adapted to the insertion flange 22 that makes up the anti-detachment component 2.

[0071] The inner side of the main body 13 is provided with a water passage 16, which is used for water flow.

[0072] The body 13 of the quick connector 1 is made of high-strength, corrosion-resistant engineering plastics (such as polyetheretherketone, PEEK) or high-quality stainless steel (such as 316L stainless steel) to meet the cleanliness and durability requirements of semiconductor manufacturing. The body 13 is cylindrical in shape, with an outer diameter designed according to the actual application scenario, generally between 50-100mm. The grip 11 is located on the outer side of the body 13, featuring an ergonomic design and a non-slip textured surface, such as a knurled pattern to facilitate handheld operation. Its length is approximately 30-50mm, and its width is adjusted appropriately according to the outer diameter of the body 13 to ensure a comfortable grip.

[0073] The body 13 and the grip 11 are manufactured by precision injection molding (if made of plastic) or machining (if made of stainless steel) to ensure dimensional accuracy and surface finish. After molding, the surface is polished and passivated (for stainless steel) to improve corrosion resistance and cleanliness.

[0074] The fastening connector 14 is a ring-shaped structure, integrally formed with the body 13 or fixed to the body 13 by welding (stainless steel) or hot-melt connection (plastic). A threaded groove is formed on one side of the fastening connector 14, and its thread specification is determined according to the size of the anti-loosening component 2's insertion flange 22, for example, using a metric fine thread M30×1.5, to ensure a tight fit with the insertion flange 22. The depth of the threaded groove is generally 10-20mm to ensure sufficient connection strength.

[0075] When installing the anti-detachment component 2, align the insertion flange 22 of the anti-detachment component 2 with the threaded groove, and then rotate the anti-detachment component 2 to connect it to the fastening mating component 14 via threads. To ensure a sealing effect, an appropriate amount of sealant (such as fluororubber sealant) can be applied to the insertion flange 22.

[0076] The water passage 16 is located inside the body 13, and its inner wall is finely polished to reduce water flow resistance and particle adhesion.

[0077] To further improve the stability of the water flow, the water passage 16 can be designed as a gradually changing streamlined structure, transitioning gradually from the inlet 12 to the outlet 15.

[0078] The ergonomic design and anti-slip texture of the grip 11 make it easier and more secure for operators to hold the quick connector 1 when installing and removing it, reducing the difficulty of operation and improving work efficiency. Especially in environments with high requirements for operational precision, such as cleanrooms, this design can reduce connection problems caused by operational errors.

[0079] The threaded connection between the fastening fitting 14 and the anti-detachment fitting 2 provides a more reliable connection strength than traditional connection methods. The threaded connection has a self-locking function, effectively preventing the anti-detachment fitting 2 from separating from the quick connector 1 under conditions of water flow impact and vibration, ensuring the stability and safety of the secondary water distribution pipeline connection. Simultaneously, the precise fit between the threaded groove and the insertion flange 22, along with the use of sealant, further improves the connection's sealing performance and reduces the risk of leakage.

[0080] The meticulously designed and polished water passage 16, along with fluid dynamics optimization measures, significantly reduces water flow resistance, ensuring uniform and stable water flow within the quick connector 1. This helps maintain stable pressure in the water distribution system, providing a stable water supply for semiconductor manufacturing equipment, thereby improving the stability of the production process and product quality.

[0081] The quick connector 1 utilizes corrosion-resistant materials and a refined surface treatment process, effectively preventing the generation of contaminants during use. Simultaneously, the smooth inner wall of the water passage 16 reduces the possibility of particulate matter adhesion, helping to maintain the cleanliness of the water distribution system and meeting the stringent requirements of semiconductor manufacturing for a highly clean environment.

[0082] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
