When it comes to maintaining your silk quilt, it's important to take care of the inner tube properly. It should never be washed or dry-cleaned, and it must be kept away from harsh chemicals. On a sunny day, you can place it on the balcony for fresh air, but avoid direct sunlight exposure. Drying time should be limited—about an hour is sufficient. Also, make sure not to store mothballs or insect repellents inside the silk quilt, as they can damage the delicate fabric over time. Over time, especially after regular use, the inner tube may develop a slight yellow tint and lose some of its fluffiness. This is completely normal and does not affect the quality or performance of the quilt. Just remember to keep it out of direct sunlight to maintain its softness and longevity. The quilt itself consists of three layers: the silk filling, the inner sleeve, and the outer quilt cover. The combination of the silk and inner sleeve is considered the core, and this part should not be washed (unless it's specifically labeled as washable). However, the quilt cover is removable and can be laundered regularly, which helps keep the inner layers clean and fresh. Silk is naturally resistant to static electricity, so it doesn't attract dust or dirt as easily as synthetic fibers or wool. This means your quilt can stay clean for years without needing frequent washing. You don’t need to worry about it getting dirty quickly, even after long-term use. If the core becomes stained accidentally, you can gently spot-clean it with a neutral detergent in a cool, shaded area. If the stain is stubborn, it’s best to consult a professional dry cleaner for local treatment. With proper care, a high-quality silk quilt can last up to 10 years or more, making it a valuable and comfortable addition to your bedroom.
Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.
