This choke valve, during cold engine starting, starts fuel to flow through the main system prematurely.
在冷启动时，阻风门使燃油提早进入主供油装置。
Due to the complication and variety in the hole especially the time that is needed to transmit pressure it is very inconvenient to use choke valve to control standpipe pressure.
但井下情况复杂多变，尤其是压力传递需要时间，给调节节流阀控制立压带来不便。
The yield of a natural gas well in an oilfield dropped suddenly, which was due to the piston sheath of the choke valve breaking into three parts with two pairs of fractures after inspection.
某油田一天然气井的产量突然下降，经检查发现该井采气装置中的节流阀柱塞套断裂为三截，形成了两对断口。
