Technical Field
[0001] This utility model relates to the technical field of water pipe welding components, specifically a corrosion-resistant water pipe welding component. Background Technology
[0002] In various water pipe connection applications, welded components have always been key components for achieving stable connection of pipeline systems. Traditional water pipe welded components can meet the pipeline connection requirements well under normal water quality and conventional environment. The water pipe and the connector are fixed by welding process, and liquid leakage is prevented by simple sealing measures. However, with the increasing complexity of industrial production and the continuous expansion of application scenarios, many occasions have put forward higher requirements for water pipe systems.
[0003] In many industrial sectors such as chemical, metallurgical, and food processing, production processes require the transportation of large quantities of liquids containing corrosive substances such as acids, alkalis, and salts. In these environments, traditional welded water pipe components face severe corrosion problems. Under long-term erosion by corrosive liquids, the surface of ordinary metal welded components gradually undergoes chemical reactions, resulting in rusting, perforation, and other phenomena. This not only reduces the structural strength of the welded components, making them prone to pipeline leaks, but also leads to waste of production materials, environmental pollution, and even potential safety accidents. Furthermore, the frequent occurrence of corrosion problems necessitates frequent maintenance and replacement of parts in the pipeline system, significantly increasing operating costs and reducing production efficiency. In some special geographical environments, such as desalination plants in coastal areas and irrigation systems near saline-alkali land, water pipes also face corrosive environments with high salinity and high humidity. Traditional welded components cannot withstand the long-term effects of such environments, and their sealing performance gradually fails due to corrosion, leading to leaks at pipe connections and affecting the normal operation of the entire system.
[0004] To address the numerous problems faced by water pipe welded components in corrosive environments, it is imperative to develop a corrosion-resistant water pipe welded component to ensure stable and reliable connections even in complex corrosive environments, thereby guaranteeing the safe and efficient operation of the water pipe system. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a corrosion-resistant water pipe weldment, which solves the aforementioned problems.
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a corrosion-resistant water pipe welding component, comprising a water pipe one and a water pipe two, wherein a connector is fixedly connected to the outer end of one end of the water pipe one, and a sealing gasket is fixedly installed on the outer end of one end of the water pipe two, and a snap-fit groove is formed on the inner surface of the sealing gasket, wherein the sealing gasket is correspondingly fitted inside the connector.
[0007] Preferably, the connector has flexible hooks on its inner four sides, and the front ends of the flexible hooks are respectively fitted into the locking grooves opened on the inner side of the sealing gasket.
[0008] Preferably, a sealing sleeve is fixedly installed on the bottom surface of the connector, and a second sealing ring is fixedly installed on the inner wall of the front end of the sealing sleeve. The second sealing ring is tightly fitted to the outer end surface of the second water pipe. A fixing cylinder is fixedly connected to the upper surface of the front end of the sealing sleeve, and bolts are threaded inside the fixing cylinder. The upper ends of the bolts extend through the inside of the connector to the outer end of the connector.
[0009] Preferably, a sealing ring is fixedly installed on the inner wall of the front end of the connector, and the lower surface of the sealing ring is tightly attached to the outer surface of the water pipe, wherein a clamp is fixedly sleeved on the outer end of the front end of the connector.
[0010] Preferably, the clamp is provided with connecting cylinders at both ends, and a screw is sleeved through the center of the two connecting cylinders. The screw extends to the outer end of the connecting cylinder at both ends, and a nut is threaded onto both ends of the screw.
[0011] Preferably, the connection between the flexible hook and the connector, as well as the threaded connection between the screw and the nut, are coated with corrosion-resistant sealant.
[0012] Compared with the prior art, this utility model provides a corrosion-resistant water pipe weldment with the following advantages:
[0013] Superior corrosion resistance ensures long-term stable operation: During the design and manufacturing process, this corrosion-resistant water pipe welded fitting utilizes corrosion-resistant materials throughout and treats key components for corrosion resistance. Whether it's the pipe material, connectors, or sealing and fastening parts, all effectively resist the erosion of corrosive substances in the transported liquid. When transporting corrosive liquids (such as industrial wastewater or brine in seawater desalination systems) for extended periods, the components will not suffer structural damage, seal failure, or loosening due to corrosion. This not only ensures the continuous and stable operation of the water pipe system, avoiding problems such as liquid leakage and water outages caused by pipeline malfunctions, but also significantly extends the service life of the entire welded fitting, reducing the high costs and time losses associated with frequent replacement of pipe components. It provides a reliable pipeline connection solution for various industrial production and domestic water use scenarios.
[0014] The combination of multiple seals and corrosion resistance achieves efficient leak prevention and convenient maintenance: This welded component uses a multi-layered sealing structure, including gaskets, sealing rings, and clamps, along with corrosion-resistant sealant applied to the connection points, to create an extremely reliable sealing system. On the one hand, it can effectively prevent liquid leakage under various complex working conditions, ensuring the efficiency and safety of the transportation process. On the other hand, due to the corrosion-resistant properties of each component and the use of corrosion-resistant sealant at key locations such as threaded connections, maintenance and disassembly can still be easily performed after long-term use. For example, when the pipeline system needs to be inspected or modified, connecting components such as screws and nuts will not seize due to corrosion, facilitating quick disassembly and reassembly, greatly improving the efficiency of maintenance work, reducing maintenance difficulty and cost, and also reducing the risk of premature failure of the pipeline system due to maintenance difficulties.

[0040] Instructions for use
[0041] This corrosion-resistant water pipe welding fitting mainly consists of water pipe 1 and water pipe 2 connected by connector 3. One end of water pipe 1 is fixedly connected to connector 3, while one end of water pipe 2 is fitted with a sealing gasket 9, which is fitted inside connector 3. Flexible hooks 10 are arranged around the inside of connector 3, with their front ends corresponding to the locking grooves on the inner side of the sealing gasket 9. The flexible hooks 10 not only provide a mechanical clamping effect, ensuring a tight fit between the sealing gasket 9 and connector 3 and preventing water pipe 2 from loosening or detaching under water flow impact, but also, by applying corrosion-resistant sealant to the connection between the flexible hooks 10 and connector 3, the sealing performance of the connection is enhanced, preventing water leakage. Furthermore, the corrosion-resistant sealant effectively resists water leakage. To prevent water from corroding the metal materials at the connection points and extend the service life of the welded parts, a sealing sleeve 11 is installed on the bottom surface inside the connector 3. The sealing ring 12 on the inner wall of its front end fits tightly against the outer surface of the water pipe 2, forming an important sealing barrier. The sealing ring 12 effectively prevents water leakage from the gap between the connector 3 and the water pipe 2. Simultaneously, the fixing sleeves 13 around the upper surface of the front end of the sealing sleeve 11, connected by threaded bolts 14, further secure the connector 3 to the water pipe 2. The bolts 14 extend through the connector 3 to the outer perimeter. Tightening the bolts 14 allows the sealing sleeve 11 to fit more tightly against the water pipe 2, enhancing the sealing effect. During this process, since the entire welded part is used for conveying… Since the liquid is being transported, it may encounter a corrosive environment. Therefore, corrosion-resistant materials are selected to manufacture components such as the sealing sleeve 11, sealing ring 12, fixing cylinder 13, and bolts 14. Furthermore, the surfaces of metal components such as bolts 14 undergo corresponding corrosion-resistant treatment to ensure that corrosion will not affect the sealing performance and connection strength during long-term use. The sealing ring 5 on the inner wall of the front end of connector 3 has its lower surface tightly fitted to the outer surface of water pipe 2, further enhancing the sealing effect. In addition, the clamp 4, which is fixedly sleeved at the outer end of the front end of connector 3, reinforces and assists in sealing the connection between water pipe 2 and connector 3. The connecting cylinders 6 at both ends of clamp 4 are secured by through-sleeved screws 7 and threaded nuts 8 at both ends. Applying corrosion-resistant sealant to the threaded connection of pipe 8 not only prevents the threads from seizing due to corrosion, facilitating later maintenance and disassembly, but also further improves the sealing performance of the connection, preventing the intrusion of external corrosive substances. Throughout the operation of the entire water pipe welded component, whether it is the pipe material (water pipe 1 and water pipe 2), the connector 3, or various sealing components (sealing gasket 9, sealing sleeve 11, sealing ring 15, sealing ring 2 12) and connecting fastening components (flexible hook 10, fixing sleeve 13, bolt 14, clamp 4, connecting sleeve 6, screw 7, nut 8), all are made of corrosion-resistant materials or have undergone corrosion-resistant treatment. This ensures that when the welded component is transporting corrosive liquids, the components will not suffer structural damage, sealing failure, or loosening due to corrosion.
