Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] As shown in Fig. 1 and Fig. 2, the present invention includes at least one joint unit A, and each joint unit A includes a connecting cylinder 1, and a cylindrical fixed ring 2 is fixedly connected to the top of the connecting cylinder 1 by bolts, and the fixed ring 2 A moving ring 5 is rotatably connected to the outside of the fixed ring 2 through a bearing 3 and a sealing ring 4, and an annular cavity 6 is formed between the fixed ring 2 and the moving ring 5 after connection. A fixed pipe joint 7 connected to the annular cavity 6 is provided on the inner wall of the fixed ring 2. The outlet end of the fixed pipe joint 7 is downwardly inserted into the connecting cylinder 1, and a flange 8 is provided at its end for connecting Piping in static spaces. For the convenience of connection, one or more operation ports 9 are opened on the wall surf...

Abstract

The present invention relates to a liquid swivel adapter device. It is characterized by that it includes at least one adapter unit, every adapter unit includes a connecting barrel, the top portion of the described connecting barrel is connected with a barrel-shaped fixed ring, the exterior of the described fixed ring is turnably connected with a moving ring by means of bearing and sealing ring, between the described moving ring and the described fixed ring a circular hollow cavity is formed, in the wall surface of the described fixed ring a fixed pipe adapter communicated with the described circular hollow cavity is set, the outlet end of the described fixed pipe adapter is downwards inserted into the described connecting barrel interior, and outside of wall surface of the described moving ring a turning pipe adopter is set, said turning pipe adapter is communicated with the described circular hollow cavity and is used for connecting with single-point mooring system pipeline.

Description

technical field [0001] The invention relates to a joint device, in particular to a liquid rotary joint device used in offshore oil fields, refineries, onshore oil and gas treatment plants and the like. Background technique [0002] At present, my country's offshore oil development is not only continuing to develop large and medium-sized oil and gas fields, but also actively developing offshore oilfields. Research and development of various equipment for offshore oilfield production facilities is also one of the important contents, such as: a large number of single-point mooring devices , its core technology - liquid rotary joint device. The liquid rotary joint device can continuously and safely transport liquid media (such as well flow or water injection) from static places in the system (such as submarine pipelines, wellhead platforms) to places that can rotate 360 ​​degrees (such as floating production and storage) It can also continuously and safely transport crude oil or...
