Abstract

一种适用于海底管道修复的智能连接器，包括连接舱、顶紧法兰、锁紧环、顶紧环、内橡胶圈、外橡胶圈及注胶阀。连接舱作为智能连接器固定端与海洋软管连接，顶紧法兰通过螺栓与连接舱相连，同时压紧顶紧环，螺栓顶紧到位后，通过锁紧环使智能连接器固定在海洋软管上，螺栓拧紧后，顶紧法兰压紧顶紧环，顶紧环斜面与锁紧环接触，压紧锁紧环。内橡胶圈放置于顶紧环与锁紧环之间并靠近海洋软管一侧，外橡胶圈放置于顶紧环与锁紧环之间并靠近连接舱一侧。连接舱上均匀分布安置注胶阀，通过向注胶阀中打入胶体，在连接舱中形成密封。在永久维修海洋软管项目中，通过智能连接器可实现海洋软管不停输、水下免焊接作业，高效快速的实现海洋软管的修复。

Description

一种适用于海底管道修复的智能连接器
技术领域
本实用新型涉及一种海洋工程领域海底管道修复装置的创新。
背景技术
海底管道是海上油气田的生命线，海底管道泄漏不仅造成油气输送和生产中断，更会造成对海洋环境的污染，给企业和国家带来巨大的经济损失。海底管道损坏都是突发性的，对海底管道的维修因其自身参数不同，所述环境条件各异，采取的方法也有所不同。目前的海洋管道修复技术主要包括水上修复和水下修复。水上焊接修复先在水下将管道切断或切除破损段，然后将两管端吊出水面，焊接好修复短节部分，做好NDT检测和涂层后放回海底。常见的水下修复方法有水下干式高压焊接修复、水下机械连接器修复、水下机械式三通修复、法兰、外卡修复等，上述方法分别存在着修复作业时间长、费用高；修复后的海管耐用年限短，也修复不能保证原有管道的整体性；适用管道操作压力及安全等级较低的管道等缺陷。
发明内容：
本实用新型解决的技术问题是提供一种智能连接器，可以实现海底管道永久修复，同时海管修复不停输并且实现水下免焊接快速连接。
本实用新型技术内容为，一种适用于海底管道修复的智能连接器，包括连接舱、顶紧法兰、锁紧环、顶紧环、内橡胶圈、外橡胶圈及注胶阀。连接舱作为智能连接器固定端与海洋软管连接，顶紧法兰通过螺栓与连接舱相连，同时压紧顶紧环，螺栓顶紧到位后，通过锁紧环使智能连接器固定在海洋软管上，螺栓拧紧后，顶紧法兰压紧顶紧环，顶紧环斜面与锁紧环接触，压紧锁紧环。内、外橡胶圈均采用耐油性好，弹性低的丁腈橡胶，内橡胶圈放置于顶紧环与锁紧环之间并靠近海洋软管一侧，防止海洋软管输送的介质渗出，外橡胶圈放置于顶紧环与锁紧环之间并靠近连接舱一侧，防止海水渗入。连接舱上均匀分布安置注胶阀，通过向注胶阀中打入胶体，在连接舱中形成密封，防止管内介质渗入锁紧环。
    本实用新型的有益效果是，在永久维修海洋软管项目中，通过智能连接器可实现海洋软管不停输、水下免焊接作业，高效快速的实现海洋软管的修复。
附图说明
下面结合附图和实施例对本实用新型做进一步说明。
图1  为智能连接器剖面图；
图2  为智能连接器侧视图。
其中  1—连接舱；2—顶紧法兰；3—锁紧环；4—顶紧环；5—内橡胶圈；6—外橡胶圈；7—螺栓；8—注胶阀。
具体实施方式：
如图1所示，顶紧法兰2通过螺栓7与连接舱1紧密连接，顶紧法兰2压紧顶紧环4，顶紧环4斜面与锁紧环3斜面紧密接触，锁紧环3产生微变形，压紧需要连接的海底管道。
如图2所示，螺栓7拧紧到位后，由注胶阀8注入胶，形成完全密封。
潜水员通过水下指挥吊机将智能连接器吊至内管管端头处，并在水下安装智能连接器，智能连接器通过安装法兰盲板进行临时封堵。通过拧紧螺栓7，使锁紧环3作用，抱死内管，向注胶阀8内注胶，进一步紧固智能连接器，内橡胶圈5、外橡胶圈6，形成两道备用密封，在保证海底管道中介质不会渗入锁紧环3，腐蚀主要受力件的同时，阻止海水渗入智能连接器内部，避免形成腐蚀。
