Background technique
Along with the fast development of China's economy, the demand of the energy is also promoted rapidly, this just impels us to need to strengthen the exploitation of domestic petroleum resources, but, the growth rate of oil consumption is unable to catch up with in the production increase of crude oil in China far away, thus impel us to have to strengthen the import of crude oil, but, strengthen crude oil import just to need to take into account scale effect, the mammoth tanker of more than 25 tons need be adopted, for adapting to the mammoth tanker of more than 25 tons, then need to build large-scale fixed crude oil terminal, and build this large-scale fixed crude oil terminal not only costly, construction period is long, the coastline resource being becoming tight day and being difficult to regenerate also will be consumed in a large number in building course, unresolved the problems referred to above, those skilled in the art wish that oil transportation process is transferred to marine single point mooring system carries out, but, carry out oil transportation operation at sea and need overcome marine poor natural condition, to ensure oil transportation process safety and to carry out reliably.
Model utility content
The utility model aims to provide one and guarantees in the terminal of single point mooring system oil transportation at sea oil transportation process, the swivel joint that its feed line can rotate relatively with flow line, guarantee that this kind of swivel joint can adapt to marine rugged environment, ensure oil transportation process safety and carry out reliably.
A kind of single point mooring described in the utility model oil transportation terminal rotating joint, comprise upper cavity and lower chamber, upper cavity port and lower chamber port are respectively arranged with mounting flange, the mounting flange of upper cavity port and the mounting flange of lower chamber port are connected as one by the floating bearing arranged therebetween, upper cavity is provided with the upper pipeline being communicated with cavity, lower chamber is provided with the lower pipeline being communicated with cavity, upper pipeline is provided with the oil inlet pipe flange plate be connected with feed line, lower pipeline is provided with the oil outlet tube flange plate be connected with flow line, the mounting flange end face of upper cavity port arranges the first annular groove, or on the mounting flange end face of lower chamber port, the first annular groove is set, the first seal ring is provided with in the first annular groove.
A kind of single point mooring described in the utility model oil transportation terminal rotating joint, be connected with in-line by oil inlet pipe flange plate, be connected with outlet line by oil outlet tube flange plate, thus, oil product can flow into upper cavity by in-line, flow into lower chamber from upper cavity again, and flow out from the outlet line that lower chamber connects, because the mounting flange of upper cavity port and the mounting flange of lower chamber port are connected as one by the floating bearing arranged therebetween, namely upper cavity and lower chamber can relatively rotate, therefore, except meeting medium transport function, relative rotation between the in-line that swivel joint adaptation single-point weathercock effect also can be made to cause and outlet line, outlet line and in-line is avoided to produce moment of torsion at weathercock effect lower stress and damage, effective weaving oil product releases, guarantee oil transportation process safety and carry out reliably, in addition, the mounting flange end face of upper cavity port arranges the first annular groove, or on the mounting flange end face of lower chamber port, the first annular groove is set, seal ring is provided with in the first annular groove, for preventing carried oil product from flowing out from the connection gap of upper and lower cavity, guarantee oil transportation process safety further and reliable.
