可调式节流阀(手动、液动)：
adjustable chokevalve(manual、hydraulic):
可调式节流阀按调节方式可分为：针形可调式、筒型可调式、孔板式设计特点
adjustablechoke valve is classified into needle-typeadjustable, barrel-type adjustable and orifice feature indesign
阀针和阀芯采用硬质合金制造，具有耐磨损、耐冲刷、抗腐蚀的性能
valve needle and valvecore are made of hard alloy steel with some properties of erosionresistance and corrosion resistance
可起到调节流量、压力和关闭的重要作用
take the effect ofadjustment of flow-rate and pressure and opening/closing the chokevalve.
针型结构主要用于采油树设备，筒型结构主要用于节流管汇
needle structure is usedfor x’mas tree assembly, and barrel forchoke manifold.
