Valve malfunction
阀门的故障原因和预防方法多样,以下是一些常见的情况:
There are various causes and prevention methods for valve failures, and the following are some common situations:
操作不当。技术人员用力过猛或操作不规范可能导致阀门失灵。
Improper operation. Excessive force or improper operation by technical personnel may cause valve failure.
阀门质量不合格或安装失误。使用劣质阀门或安装时出错,可能导致阀门故障。
Valve quality is unqualified or installation error occurs. Using inferior valves or making mistakes during installation may lead to valve failure.
阀门使用过频或维修不及时。高使用频率和缺乏及时维修可能导致部件受损加速。
Frequent use or untimely maintenance of valves. High frequency of use and lack of timely maintenance may lead to accelerated damage to components.
阀门填料失误。填料过多、填料压实程度过高或未压紧,都可能导致阀门故障。
Valve packing error. Excessive filling, excessive compaction or lack of compaction can all lead to valve failure.
密封面问题。密封面研磨不平、阀杆与关闭件连接处问题、阀杆弯曲或装配不正等都可能导致泄漏。
Sealing surface issue. Uneven grinding of the sealing surface, problems with the connection between the valve stem and the closing part, bending or improper assembly of the valve stem can all lead to leakage.
异物堵塞。阀门内部被异物或颗粒物堵塞,导致流体无法顺畅流通。
Foreign object blockage. The interior of the valve is blocked by foreign objects or particles, resulting in the inability of fluid to flow smoothly.
控制失效。传动部件损坏、阀门结构问题或其他意外情况可能导致控制失效。
Control failure. Damage to transmission components, valve structure issues, or other unexpected situations may lead to control failure.
对于这些故障,应采取相应的预防和措施,如正确安装和调整阀门、定期维护和检修、使用合适质量的阀门和填料、确保密封面平整等。此外,还应避免不当操作,保持阀门使用环境的清洁,及时处理泄漏和控制失效问题。
For these faults, corresponding prevention and solution measures should be taken, such as correctly installing and adjusting valves, regular maintenance and repair, using appropriate quality valves and packing, ensuring smooth sealing surfaces, etc. In addition, improper operation should be avoided, the valve usage environment should be kept clean, and leakage and control failure issues should be promptly addressed.
