阀门是用来控制管道中介质流量的装置,值得注意的是,“跑、冒、滴、漏”的现象多发生在阀门上,由质量低劣的阀门造成的能源浪费、设备腐蚀、物料消耗增加、停产事故已不少见。因此要求管工除应该具备处理阀门故障的应急能力外,还应该掌握阀门质量检验的方法。 The valve is used to control the medium flow in the pipeline. It is worth noting that the “running, running, driping, and leaking” phenomenon mostly occurs on the valve. The energy waste, equipment corrosion, and material consumption caused by poor quality valves increase. It is not uncommon for production cuts to stop. Therefore, it is required that the supervisor should not only have the emergency capability to deal with valve faults, but also master the method of valve quality inspection.
