Problems solved by technology

For example, when the wellhead is connected, the installation and disassembly are generally realized through the flange. It is required to be able to realize the two actions of clamping the upper flange and the lower flange together and releasing the clamped upper flange and the lower flange to meet the needs of the site. In use, this traditional connection method is a flange-type symmetrical flange connection. The flange is fixed by manually tightening the bolts in the flange installation, and the installation is time-consuming, the bolt torque is large, and the installation force is too large to easily cause slippage. Phenomenon, when the bolts are locked, the labor intensity of the operator is high, and at the same time it is time-consuming and inefficient, and it will be rusted if used in a corrosive environment for a long time. It is very inconvenient, and the entire bolt will be damaged if the force is too large, resulting in failure to use normally, so it can only be cut, and then replaced with a new bolt to fix it

Embodiment 1

[0030] Such as figure 1 Shown, the overall structure installation sectional view of the present invention.

[0031] A quick connection device for an integral wellhead, comprising a first connecting body 1, a second connecting body 2, and a pressing part 3 connecting the first connecting body 1 and the second connecting body 2, the pressing part 3 is used for When pushing the second connection body 2 to move relative to the first connection body 1, and press and fix the second connection body 2 and the first connection body 1, the first connection body 1 A locking part 5 is provided to push the pressing part 3 to move, and the moving direction of the pressing part 3 is perpendicular to the moving direction of the second connecting body 2 .

[0032] Wherein the first connecting body and the second connecting body have a circular structure as a whole, the second connecting body is inserted into the groove of the first connecting body, and a mounting groove is provided at the con...

Embodiment 2

[0060] Install the quick connection device on the upper part of the integral wellhead, and by locking the main body, where the main body of the locking part can be a locking screw, push the pressing block to activate the sealing gasket. On-site pressure tests were carried out from multiple test holes, and the test results all met the requirements. The locking screw excitation torque meets the requirements of the design specification, and the installation time is shortened by 50% compared with the conventional flange connection; the tightening torque is shortened by 50%-70% compared with the bolt torque of the traditional flange connection.

Abstract

The invention discloses a rapid connection device for an integrated well mouth. The rapid connection device for the integrated well mouth comprises a first connection body, a second connection body, and a compression part connecting the first connection body with the second connection body, wherein the compression part is used for pushing the second connection body to move relative to the direction of the first connection body, and compressing and fixing the second connection body and the first connection body; a locking part pushing the compression part to move is arranged on the first connection body; the movement direction of the compression part and the movement direction of the second connection body are mutually vertical; a connection groove is formed in a connection end of the firstconnection body; and a connection end of the second connection body is arranged in a manner of being inserted into the connection groove of the first connection body. Rapid integral installation canbe realized, time and effort are saved, the damage of parts, which is caused in an installation process, is reduced, and stable connection is achieved; and moreover, a small torque is achieved and thelabor is saved during installation, and the connection components are arranged inside, so that environment corrosion is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a connection device in a wellhead device, which is used for a quick connection device of an integral wellhead. Background technique [0002] Currently in the market, when land platforms and offshore platforms are connected to drilling and production equipment, API flanges or clamp connectors are used for connection. For example, when the wellhead is connected, the installation and disassembly are generally realized through the flange. It is required to be able to realize the two actions of clamping the upper flange and the lower flange together and releasing the clamped upper flange and the lower flange to meet the needs of the site. In use, this traditional connection method is a flange-type symmetrical flange connection. The flange is fixed by manually tightening the bolts in the flange installation, and the installation is time-consuming, the bolt torque is large, ...
