Abstract

本发明公开了一种液货舱防泄漏装置。其主要原理就是通过装置中的不锈钢空心浮球在浮力作用下封堵液货舱,使其承载的危险体不能溢出。装置中存放浮球的上端设计为锥度型式,其目的也是为了能够更好的引导液体流入浮球槽中使浮球工作起到封堵作用。使得浮球能够在液货舱浸水的早期就能够起到封堵作用。

Description

液货舱防泄漏装置
发明内容
本发明所要解决的技术问题是:提供一种在液货舱进水时候,防止被承载的液体从液货舱透气阀处溢出的液货舱防泄漏装置。
本发明解决技术问题所采取的技术方案是:
利用防泄漏装置壳体2内腔锥体滑道与垂直方向管道连通的构造和不锈钢空心浮球3的浮力作用;在正常情况下,壳体2的垂直方向管道为开通状态,浮球3置于壳体2内腔30°滑道下端槽内;当意外情况发生时,无论是液货舱开始浸水,还是从透气阀开始进水,或已经浸满水的状态,不锈钢空心浮球3都会沿壳体2上下二个方向的30°锥体滑道移动至垂直方向管道内,或者从上端透气阀法兰1处,或者从下端液货舱连接管道5处进行封堵,从而防止液货舱内的危险载体溢出。
壳体2存放不锈钢空心浮球3滑道槽的下端装有放泄螺塞4及其可拆卸式底板,以便于清洗维护。(见图1所示)
本发明解决技术问题所取得的积极效果是:本装置可与高速透气阀形成配套产品,由于一般泄漏时液货都是经过透气阀处溢出,所以本装置是安装在透气阀的下方,平时不妨碍液货舱的透气,一旦发生沉船时,可以自动封堵液货舱与透气阀连接的管道,防止被承载液体从液货舱透气阀处溢出,保护海洋环境免受有害液货的污染。
附图说明
图1为液货舱防泄漏装置图示,其中:
1、透气阀法兰  2、防泄漏装置壳体  3、不锈钢空心浮球
具体实施方式
1、当海水从透气阀法兰1处进入时,大部分海水会从顺着防泄漏装置壳体2的管道壁向下经过开通的液货舱连接管道5流入液货舱内,同时由于壳体2存放不锈钢浮球3槽的上方设计了一定高度的上下二个方向30°倾斜的锥体滑道,且滑道与壳体2垂直方向管道连通,所以会有部分海水沿着斜壁流入到浮球3的存放槽中。当水的液位超过存放槽的储水极限时,水就会溢出并向下流淌,而浮球3在浮力的作用下迅速漂浮升起,并在水流的冲击力以及海水下泄的引力作用下会滚入到液货舱连接管道5处。由于浮球3直径与液货舱管道直径一致,在浮球的自重和海水冲击的压力下浮球3会滚到一个平衡位置并被卡紧,从而起到了封堵液货舱管道的作用。
2、假设由于一定的原因,如果浮球3没有滚入到液货舱连接管道5处起到封堵液货舱的作用,那么当液货舱内进水使液货向上溢出时,整个装置壳体2内将迅速充满液体,此时浮球3在浮力作用下,就会随着液货上溢方向移动,当浮球3移动到透气阀法兰1时候,因为透气阀的进口处直径比浮球小,并且是加工成圆角达到一定精度的表面粗糙度,所以浮球3就会封堵在透气阀的进口处,从而起到了防止液货通过透气阀向外溢出的作用。
3、考虑到装置中的压力存在,并且经常有气流通过,所以在壳体2存放浮球3的滑道槽下端设计了放泄螺塞4及其可拆卸式底板,以便清洗维护。
