Abstract
本实用新型属于虹吸式自记雨量记的玻璃虹吸
管，其特征在于虹吸管的弯曲段的上顶有一倾斜平
面，该平面能将进入弯曲段的水很快引发虹吸，以消
除现有虹吸式自记雨量记存在的记录线“平顶”现象，
提高雨量资料的质量。
Description
本实用新型涉及一种倒空计量容器的流源容器，特别是自记雨量计浮筒上的玻璃虹吸管。
虹吸式自记雨量计是水文、气象及农业部门观测降水量的仪器，其结构原理是在集水浮筒侧壁装一玻璃虹吸管，当浮筒内水位升高到一定高度时，水就通过虹吸管排出。浮筒里的浮子与记录笔相连，随水位高低记录降水量。由于水与玻璃有浸润性，当浮筒里的水位升高，水在虹吸管倾斜段内呈U形面上升。当水面升至弯曲段时，由于水的重力作用，下浸润边超前上浸润边。当水到达虹吸管顶时，下浸润边就可能产生滴水或溢水。如滴水，则锯齿形记录线即出现“平顶”；如溢水、记录线则出现波浪状。这种现象已严重影响雨量资料的质量和使用价值。
本实用新型的目的就是对虹吸管加以改进，以消除上述“平顶”现象，提高雨量资料的质量。
本实用新型的任务是以下述方式完成的，即将玻璃虹吸管的弯曲段上顶压一向垂直段倾斜的平面，形成一下降坡，使水的上浸润边进入下降坡能很快引发虹吸，使下浸润边不发生滴水，从而消除“平顶”现象。
以下结合附图描述本实用新型。
图1为本实用新型压顶形玻璃虹吸管示意图。
如图1所示，玻璃虹吸管1的弯曲段4上顶有一平面3，平面3与虹吸管1的垂直段2的夹角大于90°，小于140°。当水沿虹吸管1的倾斜段5上升到弯曲段4时，水的上浸润边沿平面3下流，能很快引发虹吸，以消除“平顶”现象。
这种压顶虹吸管不受气温影响，性能稳定，寿命长，能有效地消除“平顶”现象，保证雨量记录质量。
