Deepwater quick-opening device

Abstract

The invention relates to a deepwater quick-opening device which comprises a main body assembly, a sleeve assembly and a snapping mechanism. The main body assembly comprises a base, a first guide pipe and a first limiting mechanism; the base comprises a body and a sleeving part extending outwards from one end of the body, and a sleeving hole is formed in the base; a bypass hole of which the two ends are respectively communicated to the sleeving holes is formed in the body; a first opening is formed in the side wall of the first guide pipe, and the first guide pipe is inserted into the sleeving hole from the end part of the sleeving part; the sleeve assembly comprises a second guide pipe, a sleeve arranged outside the second guide pipe in a sleeving mode and a second limiting mechanism. A second opening is formed in the side wall of the second guide pipe; the snapping mechanism is connected to the inner end of the first guide pipe and the inner end of the second guide pipe, and after the snapping mechanism is disconnected, the first limiting mechanism limits the position where the first guide pipe moves towards the outside of the sleeving part, so that the first opening and the bypass hole are staggered, the second guide pipe is separated from the sleeving hole, and the second limiting mechanism limits the position where the second guide pipe is separated from the sleeve. The second opening is sleeved with the sleeve.

Description

technical field [0001] The invention relates to the fields of petroleum and chemical industry, and more specifically, relates to a deep-water quick-opening device. Background technique [0002] With the continuous development of the offshore oil industry, more and more deep-water oil and gas fields are being gradually developed, and safety issues in deep-sea construction are also receiving more and more attention. [0003] In the development of deep-water oil and gas fields, it is usually necessary to use hoses to transport oil and gas, chemicals, seawater, fresh water, etc. The hose connections are generally fixed connections. The risk of fixed connections is that it is difficult to disconnect them in case of emergency. The medium in the pipe will leak. [0004] In order to ensure the safety of using hoses to transfer media across storage carriers during offshore construction, it is necessary to use emergency disconnection devices like land chemical transfers, that is, to ...

AI Technical Summary

Problems solved by technology

[0007] 1) Disengagement by mistake: The sea conditions are complicated, which may easily lead to the situation of disconnection by mistake of traditional disconnection devices, which will affect the normal medium transmission work and delay the construction;

[0008] 2) Difficult to restore: it is inconvenient to dispatch offshore construction materials, and the requirements for the use of equipment are higher

It is generally difficult to restore the traditional disconnecting device after separation. Once a mistake occurs, the equipment will be lost and even affect the entire construction process.

[0009] 3) Not suitable for deep water: the traditional disconnecting device is difficult to withstand the deep water high-pressure working environment, and it is impossible to realize that the emergency disconnecting device can re-seal the medium in the pipe after disconnecting underwater
