High temperature valve refers to the valve that works under high temperature conditions, which is mainly used in petroleum, chemical industry, metallurgy and other industries. Due to many challenges in the performance changes of materials, structural stability and sealing in high temperature environments, the manufacture of high temperature valves is difficult. This article will be from the high temperature valve manufacturing difficulties and technical requirements of two aspects of analysis.
First, manufacturing difficulties
1. Material selection: Under high temperature environment, the performance of the material is easy to change, such as oxidation resistance, wear resistance, strength and so on. Therefore, in the manufacture of high temperature valves, it is necessary to choose materials with excellent high temperature performance, such as superalloys, ceramics, composite materials, etc.
2. Structural design: The high-temperature valve works in a high-temperature environment, and its structural design needs to take into account the thermal expansion, thermal deformation and thermal stress and other factors of the material to ensure that the valve has good stability and sealing under high temperature conditions.
3. Sealing technology: under high temperature environment, the performance of sealing materials is easily affected, such as oxidation, wear and so on. Therefore, when manufacturing high temperature valves, it is necessary to use sealing materials with excellent high temperature sealing performance and adopt a reasonable sealing structure.
4. Manufacturing process: High temperature valve manufacturing process requirements, such as welding, machining, assembly and other processes need to be strictly controlled to ensure the quality and performance of the valve.
2. Technical requirements
1. High temperature strength: high temperature valves need to have sufficient high temperature strength to ensure that there will be no deformation or damage under high temperature conditions.
2. Oxidation resistance: high temperature valve materials need to have good oxidation resistance to resist oxidative corrosion in high temperature environments.
3. Wear resistance: High temperature valves need to have sufficient wear resistance to ensure that they will not fail due to wear under high temperature conditions.
4. Tightness: high temperature valves need to have good tightness to ensure that there will be no leakage in high temperature environments.
5. Stability: high temperature valves need to have good stability to ensure that they can work normally under high temperature conditions.
High temperature valve manufacturing has a certain difficulty, need to overcome the material selection, structural design, sealing technology, manufacturing process and other difficulties. At the same time, the high temperature valve needs to meet the technical requirements of high temperature strength, oxidation resistance, wear resistance, sealing, stability and so on in the manufacturing process to ensure the quality and performance of the valve.
