该阀门适用于高差压的蒸汽及高温热水，具较大的CV值，高幅度变化范围、低泄漏。
This valve is suitable for steam which is high differential pressure and high temperature hot water, with a large CV value, high rangeability and low leakage.
在高差压的工艺条件下，如果选型不当，控制阀往往出现冲蚀、汽蚀问题，尤其是在蒸汽系统和注水系统更为突出。
In high different pressure process condition, if the valve type selected were not correct, erosion and corrosion would occur in the trim, especially in steam systems and water spraying systems.
运用此项研究得出的一套注水井射孔完井参数预测的理论方法，为提高差油层的吸水能力、减轻油层超破压注水提供了新思路。
This injection well perforation parameter prediction theoretical method provides a new way to improve poor formation's water absorbing capability and mitigate over fracture pressure injection.
