Abstract
The invention discloses a deepwater multi-loop vertical connection terminal which comprises a male connector terminal and a female connector terminal, wherein the male connector terminal is connected with the female connector terminal through a z-direction coarse positioning device; an x-direction locking device is arranged at the part, facing the male connector terminal, of the female connector terminal. The deepwater multi-loop vertical connection terminal disclosed by the invention has the remarkable effects that the male connector terminal and the female connector terminal are preliminarily aligned through connection of the z-direction coarse positioning device when the male connector terminal and the female connector terminal are put into water, and the original longer-distance coarse alignment operation required to be carried out in the horizontal direction can be changed to be completed in the vertical direction; after coarse alignment, all needed is to carry out short-distance fine alignment and locking in the horizontal direction through the x-direction locking device, so that the mutual connection of the male connector and the female connector can be realized. With the adoption of the scheme, the horizontal telescopic distance between the male connector terminal and the female connector terminal is very short, so that the alignment difficulty is reduced and the male connector terminal and the female connector terminal are protected from being damaged.
Description
Technical field
The present invention relates to a kind of deepwater multi-loop bindiny mechanism, be specifically related to a kind of deepwater multi-loop and vertically connect terminal.
Background technology
In fluid pressure line, usually can run into the situation that pipeline is connected.In the connection of pipeline or the process of disconnection, how to ensure the seal degree of pipeline, and the connected mode optimizing jointing is a technical problem.Particularly marine environment very in, the technical difficulty of mud oil on ocean is more many greatly than land mud oil.For adapting to ocean specific work environments, have corresponding technical requirements to supporting oil drilling and extracting equipment, the most basic technical requirements has not allowed leakage.Many oil pipes can be used in oil exploitation and transportation, oil pipe arrangement is intricate, and generally length is longer, also have the place of many bendings, connect so the connection between oil pipe need use joint to reduce tubing length and floor space, jointing must have higher sealing and compressive property, and preferably can realize quick connection.
Existing fluid pressure line all adopts the mode of horizontal aligument to connect when mounted, and in order to not damage the pipeline in male and female joint terminal, joint, first male and female joint terminal needs to carry out coarse alignment in the horizontal direction, and then locks.And need male joint terminal and female joint terminal to have larger distance of stretch out and draw back in the horizontal direction with upper type.In certain circumstances, the scalable distance of the level between male joint terminal and female joint terminal is very little, cannot carry out coarse alignment; If skip coarse alignment operation and directly lock, not only difficulty increases, and easily damages male and female joint terminal.
Summary of the invention
For solving above technical problem, the invention provides a kind of deepwater multi-loop and vertically connecting terminal.
Technical scheme is as follows:
A kind of deepwater multi-loop vertically connects terminal, its main points are: comprise male joint terminal and female joint terminal, connected to rough positioning device by z between described male joint terminal and female joint terminal, described female joint terminal is provided with x to locking device towards described male joint terminal;
