Description

Technical Field

[0001] This utility model relates to the field of pipe connection and splicing technology, specifically to a carbon steel pipe with good splicing and sealing effect. Background Technology

[0002] Carbon steel pipes are a widely used type of pipe in industrial fields. Carbon steel has high strength and hardness, and can withstand greater pressure and tension. This makes carbon steel pipes perform well when transporting high-pressure fluids or bearing heavy loads. At the same time, carbon steel has good machinability and can be processed by welding, cutting, bending and other methods to meet different engineering requirements. In practical applications, the sealed splicing between two sections of carbon steel pipe can reduce pipeline leakage, improve fluid transportation efficiency, avoid energy loss and resource waste caused by leakage, and reduce operating costs. Therefore, carbon steel pipes with good splicing and sealing effects are required for use.

[0003] When using existing carbon steel pipelines, there are situations where two sections of carbon steel pipelines are connected. The precision of the splicing between the two sections of carbon steel pipelines will affect the pipeline's transportation efficiency. Traditional pipeline connection methods are not only inconvenient to operate, but also cannot guarantee the precision of the connection. They are not only inconvenient for installation, disassembly, and maintenance, but also pose a risk of resource leakage and economic losses. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a carbon steel pipe with good splicing and sealing effect, which can effectively solve the problems of inconvenient splicing operation and poor sealing performance after splicing in the existing technology.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: Refer to Figures 1 to 3 A carbon steel pipe with good splicing and sealing effect includes a No. 1 splicing pipe 1 and a No. 2 splicing pipe 2, and a splicing mechanism. The splicing mechanism includes a splicing component and two reinforcing components. The splicing component includes a No. 1 annular plate 3 fixedly connected to the side end of the No. 1 splicing pipe 1. The side wall of the No. 1 annular plate 3 near the No. 2 splicing pipe 2 is provided with an annular splicing groove 4. The end of the No. 2 splicing pipe 2 near the No. 1 annular plate 3 is fixedly connected to a No. 2 annular plate 5. The side wall of the No. 2 annular plate 5 near the No. 1 annular plate 3 is fixedly connected to an annular splicing buckle 6. The side wall of the No. 1 annular plate 1 and the No. 2 splicing pipe 2, the No. 1 annular plate 3 and the No. 2 annular plate 5 are all concentrically arranged to improve the convenience of splicing operation. The circumferential side wall of the No. 2 annular plate 5 fits against the inner wall of the shell 7 to improve the tightness of the carbon steel pipe after splicing.

[0023] The reinforcement assembly includes a bearing plate 8 fixedly connected to the side wall of the housing 7. A fixing plate 9 is fixedly connected to the bottom surface of the bearing plate 8. The side wall of the fixing plate 9 is provided with a threaded through hole 10. A threaded rod 11 is threadedly connected to the threaded through hole 10. An arc-shaped reinforcement plate 12 is rotatably connected to the end of the threaded rod 11 near the first annular plate 3 via a bearing. In each reinforcement assembly, two guide rods 13 are fixedly connected to the side wall of the arc-shaped reinforcement plate 12. Both guide rods 13 are slidably connected to the side wall of the fixing plate 9. The side walls of the two arc-shaped reinforcement plates 12 that are far apart are both in contact with the inner wall of the housing 7. A knob is fixedly connected to the end of the two threaded rods 11 that is far away from the first annular plate 3 for easy operation by the staff.

[0024] The working principle of this utility model is as follows: During splicing, first align the second annular plate 5 of the second splicing pipe 2 with the housing 7. The outer diameter of the second annular plate 5 is equal to the inner diameter of the housing 7. After alignment, insert the second annular plate 5 into the housing 7. At this time, the outer peripheral wall of the second annular plate 5 is tightly fitted with the inner wall of the housing 7. After the second annular plate 5 is inserted into the housing 7, it moves towards the first annular plate 3, which will insert the annular splicing buckle 6 into the annular splicing groove 4. The annular splicing buckle 6 and the annular splicing groove 4 have the same size. The side wall of the annular splicing buckle 6 is also tightly fitted with the inner wall of the annular splicing groove 4, thus achieving convenient operation and good splicing sealing.

[0025] After completing the above splicing, the tightness of the connection is further improved by using a reinforcement component. Taking a reinforcement component as an example, by rotating the threaded rod 11 with a knob, the threaded rod 11 will engage with the threaded through hole 10, and then move relative to the threaded through hole 10, thereby driving the arc-shaped reinforcement plate 12 to move towards the second annular plate 5, until the arc-shaped reinforcement plate 12 and the side wall of the second annular plate 5 are tightly fitted. Through the principle of thread self-locking, the first annular plate 3 and the second annular plate 5 can maintain a tight splicing state, thereby ensuring that the spliced ​​carbon steel pipe has a good sealing effect.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
