Description

Technical Field

[0001] This utility model relates to the technical field of sealing devices for oil and gas pipeline joints, and in particular to a sealing device for oil and gas pipeline joints. Background Technology

[0002] Oil and gas pipeline joints are components used to connect different pipes or fittings in an oil and gas pipeline system. They ensure the continuous transportation of oil and gas and play a vital role in the pipeline system.

[0003] Existing small oil and gas pipeline joints are used in conjunction with rubber hoses for transmitting oil and gas. The rubber hose is fitted onto the oil and gas pipeline joint and fixed with clamps. Since the seal between the rubber hose and the oil and gas pipeline joint relies on the fixing of the clamps and the deformation of the rubber hose, its sealing stability is poor. The clamps are prone to slippage, and the rubber hose will also change its deformation state. Therefore, existing oil and gas pipeline joints that lack a sealing and fixing structure are inconvenient to use. To address this, we provide an oil and gas pipeline joint sealing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing oil and gas pipeline joints that lack a sealing and fixing structure, and to provide an oil and gas pipeline joint sealing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing device for an oil and gas pipeline joint, comprising: a conveying mechanism, the conveying mechanism including a conveying pipe, a sealing mechanism provided on the outer side of the conveying pipe, the sealing mechanism including a sleeve, the sleeve being sleeved on the outer surface of the conveying pipe, the sleeve being fixedly connected to the conveying pipe, a spring piece provided at one end of the sleeve, the spring piece being fixedly connected to the sleeve, a compression block provided at one end of the spring piece, the compression block being fixedly connected to the spring piece, a threaded ring sleeved on the outer surface of the sleeve, the threaded ring being threadedly connected to the sleeve, and an injection hole provided on the sleeve.

[0006] In a preferred embodiment, the threaded ring has an extrusion groove, the sleeve has a threaded groove that matches the threaded ring, and the outer surface of the threaded ring has a rectangular groove.

[0007] In a preferred embodiment, a cross screw is fitted inside the sleeve, and the cross screw is threadedly connected to the sleeve.

[0008] In a preferred embodiment, one end of the conveying pipe is provided with a tapered tube, which is fixedly connected to the conveying pipe.

[0009] In a preferred embodiment, the tapered tube has an annular groove, and one end of the conveying tube has an output tube.

[0010] In a preferred embodiment, the output pipe is fixedly connected to the delivery pipe.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention, through the provision of a sealing mechanism, enhances the sealing effect of the oil and gas pipeline joint when it is fitted with a rubber hose, preventing leakage. Simultaneously, the rubber hose remains stable with the joint, preventing slippage and maintaining a tight seal. A threaded ring is incorporated, capable of rotating on the outer surface of the delivery pipe. This allows the threaded ring to approach the spring and the compression block, ultimately squeezing the compression block and pushing it into the annular groove. This compresses and fixes the rubber hose fitted onto the outer surfaces of the delivery pipe and the tapered pipe, ensuring stability. Furthermore, an injection hole allows for the injection of adhesive into the sleeve after the rubber hose and delivery pipe are fitted together, filling the relevant areas of the rubber hose, sleeve, and delivery pipe to achieve a seal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a sealing device for an oil and gas pipeline joint, comprising: a conveying mechanism 1, the conveying mechanism 1 including a conveying pipe 11, a sealing mechanism 2 provided on the outside of the conveying pipe 11, the sealing mechanism 2 including a sleeve 21, the sleeve 21 being sleeved on the outer surface of the conveying pipe 11, the sleeve 21 being fixedly connected to the conveying pipe 11, a spring piece 22 provided at one end of the sleeve 21, the spring piece 22 being fixedly connected to the sleeve 21, a pressing block 23 provided at one end of the spring piece 22, the pressing block 23 being fixedly connected to the spring piece 22, a threaded ring 24 sleeved on the outer surface of the sleeve 21, the threaded ring 24 being threadedly connected to the sleeve 21, an injection hole 27 being provided on the sleeve 21, a cross screw 28 being sleeved inside the sleeve 21, a pressing groove 25 being provided on the threaded ring 24, a threaded groove 26 being provided on the sleeve 21 that matches the threaded ring 24, the cross screw 28 being threadedly connected to the sleeve 21, and a rectangular groove 29 being provided on the outer surface of the threaded ring 24.

[0024] In this embodiment, a sleeve 21 is provided, and a threaded groove 26 is provided on the sleeve 21. The threaded groove 26 can be used in conjunction with a threaded ring 24, allowing the threaded ring 24 to rotate and move on the sleeve 21. When the threaded ring 24 does not squeeze the spring piece 22 and the extrusion block 23, the rubber tube can be smoothly fitted onto the outer surface of the conveying pipe 11 and the tapered pipe 12. When the threaded ring 24 squeezes the spring piece 22 and the extrusion block 23, the extrusion block 23 can gradually bring the rubber tube closer to it and finally fit it, thereby squeezing the rubber tube into the annular groove 13 opened on the tapered pipe 12, so that the rubber tube is in a stable state and will not slip. This is to cooperate with the rubber seal of the rubber tube and the conveying pipe 11, so that the seal will not be damaged, thus maintaining the sealed connection between the rubber tube and the conveying pipe 11.

[0025] Example 2

[0026] like Figures 1-4 As shown, one end of the conveying pipe 11 is provided with a tapered pipe 12, which is fixedly connected to the conveying pipe 11. An annular groove 13 is provided on the tapered pipe 12. One end of the conveying pipe 11 is provided with an output pipe 14, which is fixedly connected to the conveying pipe 11.

[0027] In this embodiment, by opening an injection hole 27 on the sleeve 21, the rubber tube can be sealed by injection after being sleeved inside the sleeve 21, resulting in a better sealing effect between the rubber tube and the oil and gas pipeline joint. At the same time, a tapered tube 12 is provided, and the tapered tube 12 is tapered, so that the tapered tube 12 can be more easily sleeved inside the rubber tube, making it easier for the rubber tube to be sleeved on the outer surface of the tapered tube 12 and the delivery pipe 11.

[0028] Working principle:

[0029] like Figures 1-4 As shown, in use, the oil and gas pipeline connector can be first connected to the rubber hose for transporting oil and gas. Then, the tapered tube 12 is inserted into the rubber hose, and the conveying pipe 11 and the tapered tube 12 are continuously squeezed, causing the rubber hose to gradually enter the sleeve 21 until it can no longer slide. Afterward, the rubber hose is fixed. The rectangular groove 29 is used to rotate the threaded ring 24. The threaded ring 24, with the cooperation of the threaded groove 26 on the sleeve 21, can rotate and move until it gradually approaches the spring piece 22 and the extrusion block 23. When the spring piece 22 first enters the extrusion groove 25 on the threaded ring 24, the spring piece 22 can be squeezed by the threaded ring 24. 4. After compression deformation, the threaded ring 24 can completely compress the spring 22 and the extrusion block 23, causing them to enter the annular groove 13 opened on the tapered tube 12. Thus, the spring 22 and the extrusion block 23 can compress and fix the rubber tube under the action of the threaded ring 24, making the rubber tube in a stable state. Then, sealant can be used to fill and seal the joint between the rubber tube and the delivery pipe 11 and the sleeve 21. At this time, the sealant is injected into the sleeve 21 through the injection hole 27 opened on the sleeve 21, and the sealant is evenly injected. Finally, the cross screw 28 is threaded to the sleeve 21 to block the injection hole 27. Thus, the rubber tube can be in a sealed connection with the oil and gas pipeline joint.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
