一种车载瓶气压测试密封装置
本技术涉及车用瓶领域,具体涉及一种车载瓶气压测试密封装置。
技术介绍
LNG车用瓶属低温压力容器,用于存储液化天然气。作为存储低温液体的压力容器,内胆必须要进行压力试验,压力试验又分为气压和水压试验,而采用气压试验为本领域常用试压手段,试压的目的在于:1、检查焊缝是否存在漏点2、检查焊缝受到压力时是否存在异常现象。3、消除焊接组织应力,确保焊缝受力均匀。气瓶内胆一端设有分配器,分配器为管路集中引出部分,周边和端面孔数量多,在进行气压试验时,必须将其上除压缩空气入口外其余各孔全部封堵,传统方法分为逐一封堵法和法兰盘螺栓固定法。以上两种方法都存在装卸非常繁琐、易磨损、难密封等问题,并且存在安全隐患。
技术实现思路
针对现有的车载瓶气压试验时,存在的易磨损、难密封的问题,本技术提供了一种车载瓶气压测试密封装置。本技术采用以下的技术方案:一种车载瓶气压测试密封装置,车载瓶包括分配器,分配器上罩有密封盖,密封盖内设置有第一密封圈和第二密封圈,密封盖的下端螺纹连接有密封螺母,密封盖与密封螺母连接处设置有密封垫,密封垫上设置有环形的凹槽,凹槽内设置有第三密封圈;在密封螺母的前部的两侧均开有前通孔,在密封螺母的后部的两侧均开有后通孔,前通孔与后通孔一一竖直对应,在对应的前通孔和后通孔中插有保险插销;所述密封盖的顶部开口,开口处焊接有充气接头,充气接头为分配器充气。优选地,所述密封盖的下部设置有外螺纹,密封螺母的内上部设置有内螺纹,外螺纹和内螺 ...
