<p>A throttle manifold for drilling simulator is composed of throttle pipes and valves arranged thereon, and the horizontal pipes and the vertical pipes of the throttle pipes are intersected vertically. Many plate valves are provided on the horizontal pipes and the vertical pipes. The horizontal pipes include an upper horizontal pipe (2) and a lower horizontal pipe (3). Both ends of the upper horizontal pipe (2) are fixed on the frame (1). One end of the upper horizontal pipe (2) is provided with a separator outlet (4), and the other end thereof is provided with a spare outlet (5). The vertical pipes include an overflow feeding pipe (6), a hydraulically operated throttle pipe (7) and a manually operated throttle pipe (8). The lower ends of the overflow feeding pipe (6), the hydraulically operated throttle pipe (7) and the manually operated throttle pipe (8) are provided with an overflow inlet (9), a hydraulically operated throttle valve (11) and a manually operated throttle valve (12) respectively. The upper end of the overflow feeding pipe (6) is fixed on the frame (1). The invention has the following advantages: achieving the vivid simulation of the throttle manifold on the drilling field, enhancing the training effect, and reducing the training cost.</p> |
