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.

這是常見的故障。在這種情況下，必須拆卸和清洗，以去除渣類。如果密封面損壞，應打磨；同時打開底塞，沖洗掉從平衡孔落入下閥蓋的渣類，沖洗管道。良工閥門廠家運輸前，將氟化物調節閥完全打開，介質流動一段時間后再納入正常運行。普通閥門調節一些容易沉淀、含有固體顆粒的介質時，往往會在節流口和導向處堵塞，氣體和蒸汽可以在下閥蓋底部的堵塞處外部沖洗。當閥門堵塞或卡住時，打開外部氣體或蒸汽閥，即可完成沖洗工作，使閥門正常運行，無需移動氟調節閥。

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.

對于小直徑的氟化物調節閥，尤其是超小流量氟化物調節閥，其節流間隙極小，介質中不能有一點渣滓。如果堵塞，在閥門前管道上安裝過濾器，以確保介質順利通過。帶定位器的氟化物調節閥是常見的故障，因為定位器工作不正常。因此，帶定位器工作時，必須處理好氣源。

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.

良工閥門廠家告訴你如果介質中的固體顆粒或管道中被沖走的焊渣和銹物因無法通過節流口而堵塞、堵塞等故障，可以改用節流間隙較大的節流部件——節流面積為開窗和開口閥芯和套筒。由于節流面積集中而不是圓周分布，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.
