管路中的流量调节装置
摘要：
本实用新型提供了一种管路中的流量调节装置，包括：至少一节流板外板，其上开设外板通孔；一节流板内板，其上开设与所述外板通孔重合的内板通孔，且所述节流板内板的外缘开设插入孔，所述节流板内板与所述节流板外板相贴合；调节手柄，其与所述插入孔相适配；通过插入所述插入孔的调节手柄的旋转带动所述节流板内板，改变所述节流板内板中内板通孔与所述节流板外板中外板通孔之间的重合面，以调节所在管路的流量。采用本实用新型不需要反复拆卸节流板，极大降低调试劳动且提高工作效率。
摘要（英）：

The utility model provides a flow regulation device in a pipeline. The flow regulation device in the pipeline comprises one or more outer plates of a throttle plate, an inner plate of the throttle plate and a regulation handle. A through hole of the outer plates is formed in the outer plates of the throttle plate. A through hole of the inner plate which is coincident with the through hole of the outer plates is formed in the inner plate of the throttle plate, inserting holes are formed in the outer edge of the inner plate of the throttle plate, the inner plate of the throttle plate fits with the outer plates of the throttle plate, and the regulation handle is matched with the inserting holes. The rotation of the regulation handle inserting into the inserting holes drives the inner plate of the throttle plate to change the coincident face between the through hole of the inner plate in the inner plate of the throttle plate and the through holes of the outer plates in the outer plate of the throttle plate, and thereby the flow in the pipeline is regulated. Through the adoption of the flow regulation device in the pipeline, disassembling the throttle plate repeatedly is not needed, the debugging labor is reduced greatly, and the working efficiency is improved.
