Description

一种储氢容器瓶口阀
技术领域
本发明涉及高压容器阀结构领域，尤其涉及一种储氢容器瓶口阀。
背景技术
随着化石能源的消耗，大气污染和温室效应的加剧，人们一直在不断的探索开发和利用清洁能源。氢能源是我国大力提倡的新能源，在能改善能源结构和降低污染排放方面优点突出。
而氢能源的运输和存放通常通过储氢容器存储。而现有储氢容器已开始逐步往非金属注塑内胆的形式发展，而储氢容器的瓶口阀座仍需采用金属阀座，因此如何设计储氢容器的瓶口阀结构，使内胆注塑时能更好的结合固定瓶口阀座，增加阀座和内胆抗拉强度和摩擦力，使两者粘接的更加牢固是该产业发展重要的研究课题。
而现有设计的储氢容器瓶口阀仍存在几个问题：
1、通常在阀体上加工密封槽，O型圈在放入密封槽的过程中都需要进行拉扯或热装，极易损坏O型圈，影响O型圈的密封效果，而挡圈在安装时也需要切口，在阀体拧紧过程中容易发生错位和变形。
2、现有储氢容器瓶口阀的塑料内胆瓶口在做压力试验到100MPa以上后发现瓶口处塑料容易发生不可复位的凹陷，影响瓶口的密封。
3、阀座的抗拉脱强度不足。
4、只考虑阀座的拉伸强度，未考虑阀座周向旋转影响牢固度。
发明内容
为解决上述技术问题，本发明设计了一种储氢容器瓶口阀。
本发明采用如下技术方案：
一种储氢容器瓶口阀，包括阀座、阀体和塑料内胆，阀座中心设置有阀口，阀口入口端设置有内螺纹，阀体的阀芯上对应设置有外螺纹，阀体和阀座通过螺纹连接，阀体的阀芯底端设置有台阶状柱面，台阶状柱面底端螺纹连接有螺母，台阶状柱面上螺母和阀芯间形成密封槽，密封槽内套入安装有挡圈和O型圈，塑料内胆的瓶口设置于阀座内，塑料内胆的瓶口端部设置有凸台，塑料内胆的瓶口外凸台内套接有外丝螺母，外丝螺母的外螺纹与阀座内设置的内螺纹连接。
作为优选，所述塑料内胆的瓶口外凸台内设置有筋板，外丝螺母由两半片组成，两半片外丝螺母夹紧筋板套接在塑料内胆的瓶口外凸台内。
作为优选，所述阀座底部设置有裙边固定套，阀座和塑料内胆外缠绕纤维缠绕层。方便将阀座紧固在纤维缠绕层和塑料内胆间。
作为优选，所述塑料内胆的瓶口、凸台和筋板一体注塑成型。
作为优选，所述裙边固定套与阀座一体成型。
本发明的有益效果是：（1）、本发明的阀座通过螺纹与外丝螺母紧固，塑料内胆的瓶口设置凸台卡住外丝螺母，可以给阀座提供拉力，协助纤维缠绕层紧固阀座；（2）、塑料内胆的瓶口外凸台内设置有筋板，固定外丝螺母的轴向转动；（3）、本发明设置外丝螺母通过阀座紧固，防止内部塑料内胆的瓶口发生变形；（4）、本发明阀体为组合件形式，设置有螺母，通过螺母和阀体的阀芯间形成密封槽，便于挡圈和O型圈套入，有效防止挡圈和O型圈在安装时遭到变形和损坏。
