A safety valve is an automatic valve mainly used in boilers, pressure vessels, and pipeline systems. When the system pressure exceeds the predetermined safety value, the safety valve will automatically release the pressure to protect the safety of equipment and personnel. Here are some basic product descriptions of safety valves:
1. Working principle: The safety valve remains closed under normal working pressure. When the pressure exceeds the set value, the valve disc automatically opens to discharge the medium to reduce the pressure and prevent equipment damage or explosion. After the pressure drops, the safety valve automatically closes to prevent the medium from continuing to be discharged.
2. * * Structural composition * *: The safety valve is mainly composed of components such as the valve body, valve cover, spring, valve seat, guide seat, and exhaust pipe. Valve bodies are usually made of metal materials with sufficient strength and corrosion resistance. Springs are used to provide the closing force of valves and maintain their sealing performance in normal working conditions.
3. * * Type * *: There are various types of safety valves, including spring type, lever type, pulse type, micro opening type, and full opening type. Spring type safety valves rely on spring force to balance the pressure of the valve disc and are suitable for most application scenarios. Full opening safety valves are suitable for gas media with large discharge capacity, while micro opening safety valves are suitable for liquid media to prevent large leakage of the medium.
4. * * Selection Guide * *: Choosing the appropriate safety valve requires consideration of working pressure, working temperature, medium characteristics, discharge capacity, installation conditions, and regulatory requirements. For example, the petrochemical industry may need to choose corrosion-resistant and high-temperature resistant safety valves, while the food processing industry may need to choose materials that are easy to clean and disinfect.
5. Installation and Maintenance: Safety valves should be installed vertically and ensure that their inlet and outlet ports are unobstructed. Special testing should be conducted before installation to check its sealing performance. Regular inspections should be conducted during use to ensure the proper functioning of the safety valve. The discharge pipe of the safety valve should avoid twists and sharp turns to reduce resistance.
6. Common faults: Safety valves may encounter problems such as leakage, failure to open or close when reaching the specified pressure, continued pressure rise after exhaust, valve disc frequency jumping or vibration, and failure to return to seat after discharge. These issues need to be resolved in a timely manner to ensure the effectiveness and service life of the safety valve.
7. * * Operating instructions * *: Keep the safety valve clean to prevent the valve body spring and other components from being filled with oil and dirt or corroded. Regularly inspect the safety valve during operation for any abnormal phenomena such as leaks, blockages, and corroded springs, and pay attention to observing whether the locking nuts of the adjusting screw sleeve and adjusting ring tightening screws are loose.
8. * * Model and Specification * *: The model representation of safety valves is usually based on the valve's structural type, material, pressure, sealing, connection method, etc. For example, models such as A40Y-16C, A40Y-40, and A40Y-64 correspond to different working pressures and applicable media.
