Description

一种卧式低温容器防过量充装装置 技术领域
本发明涉及低温压力容器设备技术领域，具体涉及一种卧式低温容器防过量充装装置。
背景技术
随着低温技术的普及，低温液体从最早的高端技术应用逐步向工业生产和民用生活领域内渗透。低温液体适用领域的拓展也带动了低温容器的设计及制造向着多元化方向改进。低温绝热气瓶发展而成的适合工业生产及民用的一种中小型低温储运设备。
低温压力容器目前开始应用于汽车、医用、LNG燃料、航天科技和国民经济各领域，取代传统的高压气瓶用以提供工业气体。在卧式低温容器使用过程中，若是充装人员过量充装，会造成巨大的安全隐患。

图3为本发明的一种卧式低温容器防过量充装装置的引流管安装示意图；

其中：1-预留筒节、2-小封头、3-封头加强筋、4-引流管、5-内后封头、 6-加强筋板、7-流通孔、8-气瓶内胆、9-进液管。
具体实施方式
参见图1-图4，本发明涉及一种卧式低温容器防过量充装装置，包括预留筒节1、小封头2、引流管4、内后封头5及气瓶内胆8，所述预留筒节1两端开口，所述小封头2焊装在预留筒节1的一端，所述预留筒节1的另一端与气瓶内胆8的内后封头5焊接固定，所述预留筒节1、小封头2和内后封头5组焊后形成了预留腔体，预留筒节1底部固定有一根插入其内部的引流管4，引流管4的另一端通向气瓶内胆8的顶部，所述气瓶内胆8的内前封头上设有进液管9。
其中，引流管4插入预留腔体外侧底部后，引流管的端面应不超过预留腔体的内壁表面。
所述预留腔体和气瓶内胆8同心组对后焊接，保证气瓶内胆受力均匀。
所述引流管4的流通直径小于进液管8的流通直径。
封头加强筋3焊装在小封头2的内部，所述预留筒节1的内壁上焊装有加强筋板6，且加强筋板6与预留筒节1内壁的连接处开设有流通孔7。在预留腔体的内壁组焊了封头加强筋3和加强筋板6后，在较高的充装压力下，可以防止受外压变形。若预留腔体具备足够的厚度能够承受相应的充装压力也可不设置封头加强筋3和加强筋板6。
所述流通孔7为半圆形，可以确保预留腔体内的液位一致。
由于引流管4出气口设置在气瓶内胆8的最顶部，当液体通过进液管9充满气瓶内胆8后，这时预留腔体中也具备了一定的压力，且引流管的流通直径远小于充装管的流通直径，气瓶内胆8内的压力会迅速升高，压力信号 立刻反馈到充装系统就停止充液。停止充液后气瓶内胆的部分液体会通过引流管4缓慢进入预留腔体，来平衡预留腔体与气瓶内胆8的压力。在内胆液位的任何状态下，都能保证低温容器的充装量为气瓶内胆8的几何容积减去预留腔体的容积，起到了防过量充装的功能。
因为气瓶内胆8的压力会随着气瓶使用而降低，这时预留腔体内的压力则会大于气瓶内胆8的压力，并且引流管4一端与预留腔体的底部连接，预留腔体内储存的介质就会通过底部的孔经过引流管4被压回气瓶内胆8，这样当气瓶内的介质用完时，也不会出现预留腔体内有液体残留的现象。
此外，因为在充装液体时，瞬间的充装压力较高，引流管4的流通直径远小于进液管9的流通直径，气瓶内胆8中的压力会随着瓶内液体的增加而逐渐升高，而此时预留腔体内还未有足够压力进入，预留筒节1和小封头2就会受到气瓶内胆8内的外压而导致变形破坏。所以在预留筒节1和小封头2内部分别增加加强筋板6和封头加强筋3，可有效防止此类情况的发生，并且加强筋板6底部开有直径25mm的流通孔7，使其不会阻碍液体在内部的流通。若预留腔体具备足够的厚度能够承受相应的充装压力也可不设置封头加强筋3和加强筋板6。
除上述实施例外，本发明还包括有其他实施方式，凡采用等同变换或者等效替换方式形成的技术方案，均应落入本发明权利要求的保护范围之内。
