    • PURPOSE: A throttle device is provided to enable the pressure of a plurality of parallel pipe rows to be changed. CONSTITUTION: A throttle device includes fluid collectors (10) and a control element (20). The fluid collector includes a fluid inlet (11) and a plurality of fluid outlets (12). The control element is mounted in an inner chamber of the fluid collector to be partially displaced and includes a plurality of orifices (21, 22). The orifices and the outlets are arranged on the control element so that the cross sections of a plurality of fluid connecting routes between the inner chamber of the fluid collector and the outlets of the fluid collectors can be changed by the relative movement of the control element. The control element is a sleeve, and the orifices are arranged on the sleeve to be corresponded to the outlets of the fluid collectors. A seal is provided between the fluid collectors so that the fluid connection between the orifices of the sleeve is not generate in a region between the inner surface (13) covering the inner chamber of the fluid collector and the outer surface (24) of the sleeve.
    • 目的:提供一种节流装置,以使得可以改变多个平行管排的压力。 构成:节流装置包括流体收集器(10)和控制元件(20)。 流体收集器包括流体入口(11)和多个流体出口(12)。 所述控制元件安装在所述流体收集器的内部腔室中,以被部分地移位并且包括多个孔口(21,22)。 孔口和出口布置在控制元件上,使得可以通过控制元件的相对运动来改变流体收集器的内腔和流体收集器的出口之间的多个流体连接路径的横截面。 控制元件是套筒,并且孔口布置在套筒上以对应于流体收集器的出口。 在流体收集器之间设置有密封件,使得在覆盖流体收集器的内部腔室的内表面(13)与套管的外表面(24)之间的区域内不会产生套管的孔口之间的流体连接 。
