Problems solved by technology

In the construction of underwater pipelines, due to the difficulties of underwater measurement and construction, the size deviation of the prefabrication and installation of underwater pipelines is relatively large, which brings a lot of difficulties to the connection of underwater pipelines, and causes the external stress of underwater flanges on pipeline deviations. Under the action, there is a problem of poor sealing, which is prone to leakage. After such an accident, it will cause oil leakage on the seabed, damage the marine environment and even endanger the personal safety of personnel on site, causing national property losses.
The angle deviation in the underwater pipeline connection not only makes the flange connection unreliable, but also makes the underwater construction complicated

Abstract

The invention discloses a small-angle adjustable spherical connector of subsea pipelines. The small-angle adjustable spherical connector comprises a sphere, a spherical flange, a locating flange, a rotary flange assembly, a stud and an adjusting bolt. The rotary flange assembly comprises a rotary flange ring and a rotary flange hub. The front end of the outwards-convex spherical surface of a spherical section of the sphere is in fit with the inwards-concave spherical surface of the inner surface of the spherical flange to form metal seal. The rear end of the outwards-convex spherical surface of the spherical section of the sphere is in fit with the inwards-concave spherical surface of the inner surface of the locating flange. The rotary flange ring and the rotary flange hub are assembled together. The rotary flange ring, the spherical flange and the locating flange are connected together through the cooperation of the stud, a first nut and a second nut. The adjusting bolt penetrates through threaded holes in the locating flange and the spherical flange and is sleeved with a spring. The small-angle adjustable spherical connector is adjustable in angle, high in reliability, easy and fast to install, compact and simple in structure, low in manufacturing cost, convenient to operate, and suitable for ordinary working conditions, acidity working conditions with H2S and CO2 and severe working conditions with sand and the like.

Description

technical field [0001] The invention relates to the technical field of submarine pipeline installation, in particular to a small-angle adjustable ball-type marine pipeline connector. Background technique [0002] Sea pipe connectors are important components of offshore platforms and underwater production systems, and are used for the connection of seabed and underwater pipelines. In the construction of underwater pipelines, due to the difficulties of underwater measurement and construction, the size deviation of the prefabrication and installation of underwater pipelines is relatively large, which brings a lot of difficulties to the connection of underwater pipelines, and causes the external stress of underwater flanges on pipeline deviations. Under the action, there is a problem of poor sealing, which is prone to leakage. After such an accident, it will cause oil leakage on the seabed, damage the marine environment and even endanger the personal safety of personnel on site,...
