摘要： An improved pressure balanced choke valve with a reversible cage style trim suitable for installation in production flowlines where it may be desired to later reverse the flow direction and use the well for water injection. The valve body (4) has end connections machined thereon and a central bore (22) for sealingly receiving a reversible cartridge assembly (6) containing the cage style trim. The cartridge assembly (6) is sealed against the valve body cavity by metal-to-metal seals and is easily removed for flow reversal by removal of a simple retainer cap (38). The cap cartridge assembly uses an inner sleeve (36) movable within a cage type trim to control the flow. The cartridge is surmounted by a bonnet assembly utilizing a handwheel operated travelling nut assembly to control movement of the inner sleeve.

摘要翻译： 一种改进的压力平衡节流阀，具有可逆的笼式装饰，适用于安装在生产流水线中，可能需要稍后反向流动方向并使用井进行注水。 阀体（4）具有加工在其上的端部连接件和用于密封地容纳包含笼式装饰件的可逆筒组件（6）的中心孔（22）。 墨盒组件（6）通过金属对金属密封件被密封抵靠阀体腔，并且通过移除简单的保持盖（38）而容易地移除用于流动反转。 盖盒组件使用可在笼式装饰件内移动的内套筒（36）来控制流动。 该盒由一个使用手轮操作的行进螺母组件的发动机盖组件来克服，以控制内套筒的运动。
