清洁要求
Cleaning requirements
经常保持阀门外部和活动部位的清洁，保护阀门油漆的完整。阀门上的灰尘用压缩空气吹扫，阀门上残留的油和介质用蒸汽吹扫干净。疏水阀应定期拆卸冲洗，防止堵塞。
Always keep the outside and moving parts of the valve clean and protect the integrity of the valve paint. The dust on the valve shall be purged with compressed air, and the residual oil and medium on the valve shall be purged with steam. The drain valve shall be dismantled and flushed regularly to prevent blockage.
定期润滑
Regular lubrication
阀门梯形螺纹、螺母及啮合部位和配合活动部位，应经常保持良好的润滑，防止锈蚀及卡死。露在外部的润滑部位，如螺纹等应注入二硫化钼润滑，既不污染灰尘，又能很好润滑;对于旋塞阀等，应定期加注润滑油，防止磨损及泄漏。
The trapezoidal threads, nuts, engagement parts and mating moving parts of the valve should always be well lubricated to prevent rust and seizure. Molybdenum disulfide shall be injected into the exposed lubricating parts, such as threads, for lubrication, which will not pollute dust, but also provide good lubrication; For plug valves, etc., lubricating oil shall be filled regularly to prevent wear and leakage.
定期维护
Regular maintenance
阀体要完好，阀件应齐全、完好，螺纹、螺母应拧紧防止松动，填料压件应及时拧紧，缺失零件应及时更换。补齐。此外，阀门不允许敲打、放置重物或站人，以免损坏阀门。
The valve body shall be intact, the valve parts shall be complete and intact, the threads and nuts shall be tightened to prevent loosening, the packing pressure parts shall be tightened in time, and the missing parts shall be replaced in time. Complete. In addition, it is not allowed to knock, place heavy objects or stand on the valve to avoid damaging the valve.
驱动装置灵活
Flexible driving device
驱动装置应外面清洁;密封良好，密封部位应严密无泄漏;传动部位应定期润滑，放置锈蚀或卡死;确保驱动装置工作正常自如，执行操作准确无误。
The driving device shall be clean outside; The seal shall be good and the sealing part shall be tight without leakage; The transmission part shall be lubricated regularly to prevent rusting or jamming; Make sure that the driving device works normally and freely, and the operation is accurate.
阀门常见问题处理
Treatment of common problems of valves
在实际生产装置中，一般阀门的泄漏情况有以下几种情况：
In the actual production unit, the leakage of general valves can be classified as follows:
阀板变形所引起的介质泄漏，呈渗流或小流量连续排放
The medium leakage caused by the deformation of the valve plate is continuously discharged in the form of seepage or small flow
阀体内有杂物，关闭不严所引起的介质泄漏，往往呈小流量泄漏
There are sundries in the valve body, and the medium leakage caused by untight closing is often small flow leakage
密封面操作造成密封不严所引起的介质泄漏，往往呈渗漏状泄漏
The medium leakage caused by loose sealing caused by the operation of sealing surface is often leaky
阀杆卡死致使阀门无法关闭所造成的介质泄漏，这样的泄漏往往在一定时间内造成相当程度的泄漏和污染
The medium leakage caused by the valve stem stuck and the valve could not be closed often causes considerable leakage and pollution within a certain period of time
密封填料不严密所造成的介质泄漏，一般表现为渗漏，但量较小
The medium leakage caused by the loose sealing packing is generally manifested as leakage, but the amount is small
阀体有砂眼所造成的介质泄漏，一般也是表现为渗漏，量较小
The medium leakage caused by sand holes in the valve body is also generally manifested as leakage, with a small amount
制造工艺上的问题所引起阀门泄漏，多为渗漏型。
The valve leakage caused by manufacturing process problems is mostly leakage type.
