Intelligent Waterproofing Technology Combining sensors and IoT technology to monitor the waterproof state of plugs in real-time, potential issues can be and addressed promptly. New Material Application Develop higher-performance waterproof materials, such as nano-coatings or self-healing materials, to further improve the plug's performance. Modular Design Develop modular waterproof plugs for easy installation and maintenance, while also reducing production costs. Green and Environmentally Friendly Adopt environmentally friendly materials and to reduce the impact of waterproof design on the environment, in line with the trend of sustainable development. Wastewater Treatment Equipment In wastewater treatment plants, electromagnetic valve plugs exposed to damp environments for long periods, and waterproof design can effectively prevent moisture ingress, ensuring stable equipment operation. Agricultural Irrigation System In agricultural irrigation, valve plugs may be subjected to erosion from rainwater or irrigation water, and waterproof design can extend their service life. Marine Equipment In marine equipment, electromagnetic valve plugs to cope with seawater corrosion and high humidity environments, and waterproof design is key to ensuring their reliability. Structural Optimization Design a compact plug structure to reduce the path moisture ingress while ensuring the convenience of plugging and unplugging operations.
Material matching Select materials that are water-resistant and corrosion-resistant based on the application environment, and ensure compatibility between the materials and plug structure. Process control Strictly control the sealing and potting processes during manufacturing to ensure a uniform and defect-free waterproof layer. Testing validation Verify the performance of the plug through experiments such as water immersion tests and pressure tests, ensuring its reliability in actual applications. Sealed structure design Form a physical barrier at the points between the plug and socket through sealing elements such as O-rings and gaskets, preventing the intrusion of moisture and dust. Waterproof material selection Use with excellent waterproof performance, such as silicone, rubber, or engineering plastics, to enhance the plug's water resistance and corrosion resistance. Potting technology Fill the plug potting materials such as epoxy resin or polyurethane, which, after curing, form a waterproof layer to protect the internal circuits and contacts. IP protection level plugs that meet the IP protection level based on the application environment, such as IP67 (dust and water resistance) or IP68 (completely water-resistant) to ensure reliability in different environments. Environmental challenges Electromagnetic valves are often used in damp, dusty, or underwater environments, such as sewage treatment, agricultural irrigation, marine equipment. The intrusion of moisture and dust can cause short circuits, corrosion, or signal transmission interruptions inside the plug, severely affecting equipment operation. Performance guarantee Waterproof design not only extends the service life of the plug but also improves the overall reliability of the electromagnetic valve, reducing maintenance costs. Safety requirements In flammable and environments, moisture intrusion may cause short circuits or even fires, making waterproof design a necessary condition for safe operation.
