Description

Technical Field

[0001] The utility model relates to the technical field of assembly connection, in particular to an assembly structure of tertiary oil and gas recovery and processing equipment. Background Art

[0002] Tertiary oil and gas recovery and processing equipment refers to the separation of oil and gas through technical means such as condensation or membrane separation for high-pressure saturated oil and gas in oil storage tanks, and the conversion of gaseous oil into liquid for recovery.

[0003] Connectors are used to install cables for sensor probes in pressure vessels and to connect pipes in tertiary oil and gas recovery equipment. However, most connectors have rigid connections at both ends, such as between two pipe sections. During disassembly, after unscrewing one end of the connector, the pipe ends must be bent and offset to dislocate the two pipes, making the connector difficult to remove.

[0004] To this end, the utility model provides an assembly structure of a tertiary oil and gas recovery and processing device to improve the convenience of assembly and disassembly. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose an assembly structure for tertiary oil and gas recovery and processing equipment.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An assembly structure for tertiary oil and gas recovery and processing equipment includes two axially sliding threaded joints and a deformable connecting pipe arranged between the two sets of threaded joints. A pressure relief pipe is connected to the side of the connecting pipe. The two threaded joints are connected to the connecting pipe at one end with a polygonal convex eaves.

[0008] Preferably, an external cover is fixed to one opposite end of the two threaded joints, one external cover is provided with a guide column, and the other external cover is provided with a shaft sleeve sleeved on the guide column.

[0009] Preferably, a notch is provided on the side of the external cover.

[0010] Preferably, the connecting tube is any one of a flexible tube and a telescopic tube.

[0011] Preferably, the external cover is fixed on the end face of the polygonal convex eaves, and the polygonal convex eaves is threadedly connected to the threaded joint.

[0012] Preferably, a connecting column is fixed on the side of the shaft sleeve, and a mounting column is provided on the end face of the external cover matched with the shaft sleeve, and the mounting column is universally connected to the connecting column.

[0013] Compared with the prior art, the present invention provides an assembly structure for a tertiary oil and gas recovery and processing device, which has the following beneficial effects:

[0014] During removal, a wrench is placed on the polygonal convex flange and twisted, causing the two threaded connectors to rotate synchronously and move closer together, separating them from the two pipe ports simultaneously and achieving simultaneous removal of the two ports. The two threaded connectors move closer together and contract, eliminating the need to bend the pipes during removal, reducing installation difficulty and hassle while also avoiding damage to the pipes caused by bending or twisting.

[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on an examination of the following; or may be taught from the practice of the present invention to some extent.

[0021] The following is a combination of the appended examples of the present invention Figure 1-4 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1. In order to solve the problems existing in the prior art, this embodiment provides an assembly structure of a tertiary oil and gas recovery and processing equipment, including two axially sliding threaded joints 1 and a deformable connecting pipe 8 arranged between the two groups of threaded joints 1. The connecting pipe 8 is connected to a pressure relief pipe 9 on the side, and the two threaded joints 1 are connected to the connecting pipe 8 at one end with a polygonal convex eaves 2.

[0023] According to the above technical solution, there are two usage states:

[0024] The first is the connection between hard pipes:

[0025] During use, the two threaded connectors 1 are screwed into the two pipe ports, creating a through-connection between the two pipes. To remove the connector, simply tighten a wrench onto the polygonal flange 2 and twist it, causing the two threaded connectors 1 to rotate synchronously and approach each other. During this process, the two threaded connectors 1 simultaneously separate from the two pipe ports, allowing for simultaneous removal of the two connections. The two threaded connectors 1 shrink as they move closer together, eliminating the need to bend the pipes during removal. This reduces installation complexity and hassle while also preventing potential damage from twisting and twisting the pipes.

[0026] The pressure relief pipe 9 on the side wall of the connecting pipe 8 is connected to the oil tank storing oil and gas through an electric control valve. When the oil and gas flow pressure in the pipeline is too high, it opens, allowing part of the oil and gas to flow along the pressure relief pipe 9 into the oil tank again, thereby reducing the internal pressure at the pipeline connection.

[0027] The second type is that the cable of the sensor probe in the pressure vessel is connected to the control box through a protective sleeve:

[0028] During use, one end of the two threaded connectors 1 is connected to the connector at the pressure vessel cable inlet, and the other end is connected to the casing. Oil and gas that have seeped into the casing can be discharged through the pressure relief pipe 9, preventing them from entering other electronic equipment along the casing and causing explosions or other safety hazards, such as entering a control box.

[0029] In this embodiment, the connecting tube 8 is any one of a flexible tube or a telescopic tube, such as a corrugated tube or a rubber tube, to achieve a deformable connection of the connecting tube 8.

[0030] In this embodiment, an external cover 3 is fixed to the opposite end of the two threaded joints 1. One external cover 3 is provided with a plurality of guide posts 4, and the other external cover 3 is provided with a shaft sleeve 5 sleeved on the guide posts 4. Thus, the two threaded joints 1 are axially slidingly matched.

[0031] In a further embodiment of this solution, a notch 10 is provided on the side of the external cover 3. If an external tool such as a wrench is unavailable for use with the polygonal convex rim 2, a rod-shaped tool such as a screwdriver or a metal post can be inserted directly into the notch 10 to pry the external cover 3 as a whole, thus reducing the tool requirements for removal.

[0032] In Example 3, the external cover 3 is fixed to the end face of the polygonal convex eave 2, which is threadedly connected to the threaded connector 1. This allows the spacing between the two threaded connectors 1 to be adjustable, so as to be suitable for connecting pipe ports with different spacings within a certain range.

[0033] Example 4, in a further embodiment of the present invention, a connecting column 6 is fixed to the side of the shaft sleeve 5 , and a mounting column 7 is provided on the end face of the external cover 3 matching the shaft sleeve 5 , and the mounting column 7 is universally connected to the connecting column 6 .

[0034] According to the above technical solution:

[0035] A universal joint effect is formed between the guide column 4, the shaft sleeve 5, the connecting column 6 and the mounting column 7. The two threaded joints 1 can deflect within a certain range to be suitable for connecting pipes with uneven ports.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
