Description

Technical Field

[0001] The utility model relates to a joint device for connecting pipelines for offshore oil, water and gas transportation, in particular to a quick joint conversion tool. Background Art

[0002] During the production process, offshore oil and gas production facilities usually need to take and use factory air, instrument air, reclaimed water, fresh water, seawater and diesel. In particular, the taking and use of reclaimed water, fresh water and factory air are more common. However, due to various reasons, the supply points of the above media are generally far away. In order to facilitate the taking, it is necessary to set up a public station as a transfer station for pipeline connection or transfer. When connecting or transferring pipelines, joints are needed. Joints are intermediate connection tools for pipeline connection or transfer. The intermediate connection tools can realize quick connection or disassembly between pipelines. Joints can be divided into male joints and female joints. Only when the male joint and the female joint are paired with each other and the specifications and dimensions between the two are completely consistent, can the pipeline be quickly and firmly connected, thereby ensuring the normal circulation of the above media in the pipeline.

[0003] In previous pipeline connection or transfer operations, it is common to encounter situations where the connectors of the connecting pipelines do not match. For example, the output end of the connecting pipeline at the public station is a male connector, while the input end of the connecting pipeline that needs to be connected to the offshore oil and gas production device is also a male connector. Because the connecting pipeline connected to the offshore oil and gas production device is sometimes taken out for use when needed temporarily, if it is not known in advance that the output end of the pipeline at the public station is also a male connector, it cannot be successfully connected together for use. Conversely, if there are female connectors on both the output and input ends, the pipelines cannot be successfully connected. Even if the output and input ends are male connectors and female connectors that match each other, they cannot be successfully connected because their size specifications do not match or match, which adds trouble to the work. In order to solve this troublesome problem, one of the two unmatched male connectors must be replaced with a female connector, or one of the two female connectors must be replaced with a male connector, and the specifications and dimensions of the interconnected male connector and female connector must be kept consistent, so that a quick and stable connection can be achieved.

[0004] If the work situation is urgent, and it is discovered temporarily that a pair of connectors are not matched with each other and / or the specifications and sizes are inconsistent, or if this situation occurs every time, then not only is it necessary to find a suitable connector for replacement, but the suitable connector must also be disassembled before it can be installed on the pipeline that needs to be connected. After use, the connector must be disassembled and installed back on the original pipeline. This is not only time-consuming and labor-intensive, but may also cause damage to the pipeline when disassembling and installing the connector, and even affect the normal development of oil and gas production. Utility Model Content

[0005] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a quick connector conversion tool, which can quickly pair a male head and / or a female head, and can quickly match a male head and / or a female head with matching specifications and dimensions. It has a simple structure, convenient operation, and saves time and effort, making the pipeline connection or transfer flexible and stable, thereby ensuring the normal operation of offshore oil and gas production.

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

[0007] A quick connector conversion tool comprises a male head, a female head and an intermediate connector. The intermediate connector is a hollow structure. The male head and the female head are both connected to the intermediate connector and communicate with the hollow structure of the intermediate connector. A pressure gauge is installed in the middle of the intermediate connector.

[0008] Furthermore, the upper and lower surfaces of the intermediate connector are both planes, and the two planes are parallel to each other. The intermediate connector is in a drum shape, and the male head and the female head are respectively arranged on the circular ring surfaces of the drum shape.

[0009] Furthermore, four male and female heads are provided respectively, and are fixedly arranged on the intermediate connector, and adjacent male and female heads, and / or adjacent male and male heads, and adjacent female heads are spaced at an angle of 45°.

[0010] Furthermore, the male head and the female head can be connected to the conversion head respectively to make the flow opening of the joint smaller.

[0011] Furthermore, both the male head and the female head are provided with stop valves.

[0012] Furthermore, the male head has two sizes, one is 1" and the other is 3 / 4". There are two 1" male heads, which are symmetrically arranged, and there are two 3 / 4" male heads, which are symmetrically arranged.

[0013] Furthermore, the female head has two sizes, one is 1" and the other is 3 / 4". There are two 1" female heads, which are symmetrically arranged, and there are two 3 / 4" female heads, which are symmetrically arranged.

[0014] Furthermore, the conversion heads are provided with two, one of which is a 1" female to 1 / 2" male head, and the inlet and outlet of the fluid medium entering and exiting the intermediate connector are changed by connecting the 1" female to 1 / 2" male head to the 1" male head, so that the outlet or inlet is reduced by half;

[0015] Another conversion head is 1" male to 1 / 2" female. Connect the 1" male to 1 / 2" female to the 1" female. By connecting the 1" male to 1 / 2" female, the inlet and outlet of the fluid medium in and out of the intermediate connector can be changed, reducing the outlet or inlet by half.

[0016] Furthermore, by arranging a diversion structure in the hollow of the intermediate connector, the diversion structure is composed of multiple diversion pipes, each of which is individually connected to an inlet joint and an outlet joint, and a pressure gauge is added to each diversion pipe, and the pressure gauges are all located on the same drum-shaped surface of the intermediate connector. Different types of fluid media can be connected at the same time through the diversion structure for circulation.

[0017] Furthermore, the inlet connector may be a male connector or a female connector, and the outlet connector may be a male connector or a female connector.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] The intermediate connector is set as a hollow structure, and the fluid medium is collected in the hollow structure of the intermediate connector, which makes it easier to divert the multiple male and female connectors connected to the connector to the downstream pipeline.

[0020] The upper and lower surfaces of the intermediate connector are set to a flat structure, similar to a hollow drum. When placed on the ground, the contact area with the ground can be increased, the stability is stronger, and it is not easy to tip over.

[0021] A pressure gauge is set on the intermediate connector. The pressure gauge is connected to the hollow space of the intermediate connector and can be used to monitor the pressure in the pipeline. When the pipeline needs to be disassembled, it can be judged whether it is safe to disassemble the pipeline by observing the indication of the pressure gauge to avoid disassembly under pressure and cause personal injury.

[0022] The stop valves are respectively set on the male and female ends, and the pressure and flow can be controlled by switching the stop valves.

[0023] The stop valve can be used to isolate the joint and adjust the flow rate. When the downstream user does not need such a large flow rate, the flow rate can be controlled by switching the stop valve.

[0024] The utility model solves the problem of temporarily finding a suitable joint when the joints are not paired or the sizes do not match during the pipeline connection or transfer process, thereby avoiding the problem of pipeline damage and personal injury during repeated disassembly and installation of the joints.

[0025] When connecting pipelines, operators only need to use the quick connector conversion tool of the utility model at the public station to meet the pipeline connection requirements of all public stations at the offshore oil field. Therefore, the quick connector conversion tool of the utility model has the characteristic of strong versatility.

[0026] The utility model has the advantages of simple structure, stability, strong versatility, easy connection and storage, and can avoid accidents of injury to people. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0039] like Figure 1 , Figure 2 As shown, a quick connector conversion tool includes a male head, a female head, and an intermediate connector 1. The intermediate connector 1 is a hollow structure. The male head and the female head are both connected to the intermediate connector 1 and communicate with the hollow structure of the intermediate connector 1. A pressure gauge 2 is installed in the middle of the intermediate connector 1. The pressure gauge 2 is used to monitor the pressure in the intermediate connector 1.

[0040] The upper and lower surfaces of the intermediate connector 1 are both planes, and the two planes are parallel to each other, and the side surface thereof is a circular ring structure.

[0041] The intermediate connector 1 is in a drum shape, and the male connector and the female connector are respectively arranged on the circular ring surface of the drum shape.

[0042] There are four male and female connectors, respectively, which are fixedly mounted on the intermediate connector 1. Adjacent male and female connectors, and / or adjacent male and male connectors, and adjacent female and female connectors are spaced at an angle of 45°.

[0043] The male head and the female head can be connected to the conversion head respectively to make the flow opening of the joint smaller.

[0044] A measuring range of the pressure gauge 2 is 10 kg.

[0045] The male and female ends are both provided with stop valves 9 .

[0046] The male head has two sizes, one is 1" and the other is 3 / 4". There are two 1" male heads 3, which are symmetrically arranged, and there are two 3 / 4" male heads 6, which are symmetrically arranged.

[0047] The female head has two sizes, one is 1" and the other is 3 / 4". There are two 1" female heads 5, which are symmetrically arranged. There are also two 3 / 4" female heads 4, which are symmetrically arranged.

[0048] The conversion heads are provided with two, one of which is a 1" female to 1 / 2" male 7. By connecting the 1" female to 1 / 2" male 7 to the 1" male 3, the inlet and outlet of the fluid medium in and out of the intermediate connector 1 can be changed by connecting the 1" female to 1 / 2" male 7, so that the outlet or inlet is reduced by half, and the flow rate of the fluid medium is reduced to suit the use requirements.

[0049] Another conversion head is a 1" male to 1 / 2" female 8. The 1" male 3 to 1 / 2" female is connected to the 1" female 5. The inlet and outlet of the fluid medium entering and exiting the intermediate connector 1 can be changed by connecting the 1" male to 1 / 2" female 8, so that the outlet or inlet is reduced by half, and the flow rate of the fluid medium is reduced to suit the use requirements.

[0050] The female head is provided with a buckle 10, which is movable and used to connect and lock with a male head of corresponding size. That is, the female head is connected with the male head through the buckle 10. It is only necessary to insert the male head of corresponding size into the female head and then tighten the clip on the female head. The connection between the female head and the male head through the buckle 10 described in the utility model belongs to common knowledge in the technical field and will not be repeated here.

[0051] To prevent loss, the 1" female to 1 / 2" male 7 is usually connected to the 1" male 3. At the same time, the 1" male to 1 / 2" female 8 is also usually connected to the 1" female 5. When in use, they can be disassembled or connected according to usage requirements.

[0052] For ease of use, sometimes the 1" female to 1 / 2" male 7 and the 1" male to 1 / 2" female 8 are connected to the two 1" male and female heads in the form of an anti-drop rope.

[0053] The material used in the utility model is stainless steel, which is corrosion-resistant and particularly suitable for a humid environment such as the sea. Moreover, the material is inexpensive and easily available.

[0054] At present, a large number of engineering projects on oil field sites need to use the quick connector conversion tool. Because the quick connector conversion tool is small in size, it can be made with only some engineering leftovers, and has the characteristic of low production cost.

[0055] The 1" male connector 3, 3 / 4" male connector 6, 1" female connector 5, 3 / 4" male connector 6, 1" male connector to 1 / 2" female connector 8 and 1" female connector to 1 / 2" male connector 7 have covered all pipeline connectors of the utility stations currently on the offshore oil field. When the pipeline needs to be connected, no matter how big the connector size between the utility station and the pipeline is, quick connection can be achieved by connecting the quick connector conversion tool.

[0056] The male and female heads provided on the intermediate connector 1 can be connected to the fluid medium by using any four connectors, and the remaining four connectors are used to divert the fluid medium. The other two conversion heads are used for male or female connection according to the needs of use to reduce the diversion outlet to meet the use requirements.

[0057] There are a total of 10 male connectors, female connectors and conversion connectors mentioned above. Theoretically, when the upstream flow is large enough, connecting the quick connector can achieve a one-to-many split form, which can divide up to 8 pipelines, one of which is the access pipeline and the other seven are the outgoing pipelines. Compared with the ordinary public station 1-to-1 connection form, there are 7 more users invisibly.

[0058] The quick connector conversion tool of the utility model can be placed at a public station for storage and ready for use, which greatly facilitates the next use.

[0059] The utility model can also set a diversion structure (figure omitted) in the hollow of the intermediate connector 1. The diversion structure is composed of multiple diversion pipes, each of which is separately connected to an inlet joint and an outlet joint, and a pressure gauge is added to each diversion pipe. The pressure gauges are all located on the same plane of the intermediate connector 1. Different types of fluids can be connected through the diversion structure. For example, when a water transport test is required, factory air and fresh water can be connected at the same time to simulate oil and gas operation. According to actual needs, fresh water, seawater, factory air, instrument air, diesel and other media can be introduced at the same time. At the same time, in order to facilitate clear knowledge of the pressure gauge corresponding to each diversion pipe, the same digital label can be marked on the inlet joint and outlet joint of each diversion pipe and the corresponding pressure gauge. The digital label is placed in a conspicuous position so that it is easy to see during use to avoid confusion or misuse during use.

[0060] Here’s how to use it:

[0061] 1. At the utility station, match the connector on the quick connector conversion tool with the connector of the medium supplied at the utility station and connect them according to the type of medium to be used. For example, if fresh water is needed, you first need to find the fresh water pipeline at the utility station, and then match the connector on the quick connector conversion tool according to the type and size of the fresh water pipeline connector;

[0062] 2. According to the size and type of the required connecting pipeline, match it with the connector at the outlet of the quick connector conversion tool and connect it;

[0063] 3. Close the stop valves 9 of all vacant joints except the connecting pipelines, and then open the pressure gauge 2 on the intermediate connector 1;

[0064] 4. Open the isolation valve of the supply medium pipeline at the utility station, and open the stop valve 9 of the quick connector conversion tool (the one located upstream is also called the inlet valve), and then slowly adjust the stop valve 9 of the quick connector conversion tool (the one located downstream is also called the outlet valve) according to user needs to control the flow;

[0065] 5. After the operation is completed, first close the isolation valve at the utility station, and use pressure gauge 2 to determine that there is no pressure in the pipeline. That is, after the pointer of pressure gauge 2 returns to zero, remove the quick connector conversion tool and the downstream pipeline;

[0066] 6. When the quick connector conversion tool is needed to separate multiple pipelines, several pipelines can be connected downstream of the quick connector conversion tool as needed, up to 7 downstream pipelines, and then steps 3-5 can be repeated.

[0067] Many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore, they should not be construed as limiting the scope of protection of the present invention.

[0068] In summary, although the present invention lists the above-mentioned preferred embodiments, it should be noted that although technicians in this field can make various changes and modifications, unless such changes and modifications deviate from the scope of the present invention, they should be included in the protection scope of the present invention.
