Abstract
The utility model relates to an ultrahigh pressure pipeline connecting device, which is mainly suitable for connecting petroleum drilling and logging equipment and a pipeline, and can ensure sealing and bear ultrahigh pressure in the drilling and logging process when connecting the equipment and the pipeline. The device is characterized in that the device shell is connected with the connecting pup joint through metric threads, an O-shaped ring and a check ring in a sealing groove of the connecting pup joint are matched with a reamed hole in the device shell to form sealing, and the other end of the connecting pup joint is connected in a connection mode matched with an ultrahigh-pressure pipeline. The ultrahigh-pressure pipeline connector has the advantages that the metric threaded connection mode solves the problem that NPT threads cannot be used for ultrahigh-pressure pipeline connection, and meanwhile the O-shaped ring and the check ring are adopted to solve the sealing problem of ultrahigh-pressure pipeline connection; the connecting device is simple in overall structure and good in sealing performance; the connection form is simple, operation is convenient, and installation is easy; processing and manufacturing are easy.
