In the process of using the fluorine lined regulating valve, the fluorine lined regulating valve sometimes gets stuck or blocked due to the medium principle, and cannot work normally. At this time, it should be avoided or handled. The following methods of Lianggong valve manufacturer are for reference only: the welding slag, rust and slag in the pipeline are blocked or blocked in the throttle opening, guide part and balance hole of the lower valve cover, resulting in the surface of the valve core, the guide surface, the scratch, and the indentation on the sealing surface. This situation often occurs in the initial stage of transportation after the new transportation system and overhaul.

这是常见的故障。在这种情况下，必须拆卸和清洗，以去除渣类。如果密封面损坏，应打磨；同时打开底塞，冲洗掉从平衡孔落入下阀盖的渣类，冲洗管道。良工阀门厂家运输前，将氟化物调节阀完全打开，介质流动一段时间后再纳入正常运行。普通阀门调节一些容易沉淀、含有固体颗粒的介质时，往往会在节流口和导向处堵塞，气体和蒸汽可以在下阀盖底部的堵塞处外部冲洗。当阀门堵塞或卡住时，打开外部气体或蒸汽阀，即可完成冲洗工作，使阀门正常运行，无需移动氟调节阀。

This is a common fault. In this case, it must be disassembled and cleaned to remove slag. If the sealing surface is damaged, it shall be polished; At the same time, open the bottom plug, flush the slag that falls into the lower valve cover from the balance hole, and flush the pipeline. Before transportation, Lianggong valve manufacturer shall fully open the fluoride control valve, and bring the medium into normal operation after flowing for a period of time. When regulating some media that are easy to precipitate and contain solid particles, ordinary valves often block at the throttle and guide, and gas and steam can be flushed outside at the plug at the bottom of the lower valve cover. When the valve is blocked or jammed, open the external gas or steam valve to complete the flushing work and make the valve operate normally without moving the fluorine control valve.

对于小直径的氟化物调节阀，尤其是超小流量氟化物调节阀，其节流间隙极小，介质中不能有一点渣滓。如果堵塞，在阀门前管道上安装过滤器，以确保介质顺利通过。带定位器的氟化物调节阀是常见的故障，因为定位器工作不正常。因此，带定位器工作时，必须处理好气源。

For small diameter fluoride regulating valves, especially for ultra-small flow fluoride regulating valves, the throttling clearance is very small, and there should be no dross in the medium. If it is blocked, install a filter on the pipe in front of the valve to ensure the smooth passage of the medium. Fluoride regulating valve with positioner is a common fault because the positioner works abnormally. Therefore, when working with a positioner, the air source must be handled properly.

良工阀门厂家告诉你如果介质中的固体颗粒或管道中被冲走的焊渣和锈物因无法通过节流口而堵塞、堵塞等故障，可以改用节流间隙较大的节流部件——节流面积为开窗和开口阀芯和套筒。由于节流面积集中而不是圆周分布，故障可以很容易地排除。

The manufacturer of Lianggong valve tells you that if the solid particles in the medium or the welding slag and rust washed away in the pipeline are blocked and blocked due to the failure of passing through the throttle orifice, the throttle parts with large throttle clearance can be used instead - the throttle area is the opening and opening valve core and sleeve. Because the throttling area is concentrated rather than circularly distributed, the fault can be easily eliminated.
