Description

一种高压氢气瓶安全释放阀
技术领域
本发明涉及安全阀技术领域，尤其涉及一种高压氢气瓶安全释放阀。
背景技术
随着人类对能源的需求量日益增长，化石燃料等不可再生能源即将面临着枯竭的危险，而且化石燃料对环境的影响也不能忽视，故而开发和利用新能源成为越来越迫切的要求，而氢气作为一种新能源，是世界公认的清洁能源，越来越受人们的关注。
同时，氢气是一种易燃易爆的气体，其与氟、氧、一氧化碳以及空气混合均有爆炸的危险，而氢气通常被压缩存储在特制的氢气瓶中，从而氢气瓶内的气压往往比较大，顾在氢气瓶存储和使用过程中，若受环境的影响使得氢气瓶内温度和气压过大时，就有可能造成爆炸，从而引发安全事故。
为此，现有也有设计一些氢气瓶安全阀，中国专利公告号CN109099311A，公告日2018年12月28日，公开了一种氢气瓶安全阀，包括接头、安全螺栓、引流罩和爆破片，接头上沿其上下端方向贯穿设有通孔，安全螺栓和引流罩均连接于接头的上端且安全螺栓的头部位于引流罩的内部，接头的上表面、安全螺栓的头部和引流罩的内壁之间形成有容纳腔，引流罩上设有连通于容纳腔的接口，安全螺栓上设有用于连通通孔和容纳腔的孔道，爆破片位于安全螺栓和接头之间用于将通孔和孔道隔开，孔道内填充有易熔合金。当氢气瓶内气压和温度分别达到爆破片的爆破压力和易熔合金的熔点后，该氢气瓶安全阀自动对氢气瓶内氢气进行泄压，得以提高氢气瓶使用的安全性，避免引发安全事故。
但此类氢气瓶安全阀的爆破压力限定，无法调节，适用范围小。
