Description

Technical Field

[0001] The utility model relates to a pipeline docking head, in particular to a two-way pipeline docking head. Background Art

[0002] Pipeline docking refers to connecting two sections of pipelines in a specific way to form a continuous pipeline system, ensuring the smooth flow of fluids (such as water, gas, oil, etc.) or solid materials (such as powders, granules). There are various pipeline docking methods, mainly depending on factors such as the material, diameter, working pressure, medium characteristics of the pipeline, and on-site construction conditions.

[0003] Chinese Patent CN220910721U discloses a pipeline docking head adjusting mechanism, including an outer pipe and an inner pipe. The inner diameter of the outer pipe is larger than the outer diameter of the inner pipe. Fixed cylinders are fixedly installed at the opposite ends of the outer pipe and the inner pipe. Fixed components are fixedly installed on both side surfaces of the two fixed cylinders. The fixed component includes an airbag fixedly installed on the inner wall of the fixed cylinder. One side surface of the airbag is connected to an air inlet pipe extending outside the fixed cylinder, and a gas valve is fixedly installed on the air inlet pipe. With this pipeline docking head adjusting mechanism, by setting the fixed component, when the staff installs the pipeline docking head, the pipeline can be fixed during installation, facilitating the staff to install it. However, when the outer pipe and the inner pipe of this patent are connected, it is achieved through the thread between the inner pipe and the outer pipe. This also means that during pipeline docking, one of the outer pipe and the inner pipe or both need to be rotated simultaneously. However, when any end of the outer pipe or the inner pipe is already connected to the pipeline system, it is difficult to achieve docking by rotation. Moreover, when the diameter of the outer pipe or the inner pipe is relatively large, rotation is very laborious and troublesome. Summary of the Utility Model

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the technical problem of the utility model is: to provide a two-way pipeline docking head to overcome the above-mentioned shortcomings of the prior art.

[0005] Technical solution: A two-way pipe connector includes pipe I, pipe II and a connecting ring. Pipe I and pipe II are connected through the connecting ring. A connector I is connected to the left end of pipe I. The inner diameter of connector I is the same as that of pipe I, and the outer diameter of connector I is smaller than that of pipe I. Wedge-shaped grooves I are evenly spaced on the outer side surface of connector I. A connector II is connected to the right end face of pipe II. The inner diameter of connector II is the same as that of pipe II, and the outer diameter of connector II is smaller than that of pipe II. Wedge-shaped grooves II are evenly spaced on the outer side surface of connector II. The wedge-shaped grooves I and the wedge-shaped grooves II are symmetrically arranged with respect to the docking surface of pipe I and pipe II. Wedge-shaped blocks I are evenly spaced and installed on the right side of the inner wall of the connecting ring, and wedge-shaped blocks II are evenly spaced and installed on the left side of the inner wall of the connecting ring. The inner diameter of the connecting ring is the same as the outer diameter of connector I. Sealing rings are sleeved on connector I and connector II through grooves. Pipe I is inserted into the connecting ring through connector I, and the wedge-shaped blocks I in the connecting ring are stuck in the wedge-shaped grooves I. Pipe II is inserted into the connecting ring through connector II, and the wedge-shaped blocks II in the connecting ring are stuck in the wedge-shaped grooves II.

[0006] In the present utility model, due to the arrangement of the wedge-shaped blocks I and the wedge-shaped blocks II in the connecting ring, in cooperation with the wedge-shaped grooves I and the wedge-shaped grooves II opened in pipe I and pipe II, it is not only convenient for docking but also can prevent pipe I and pipe II from separating. The sealing ring can prevent liquid from flowing out through the gap when flowing through pipe I and pipe II. Brief description of the drawings

Detailed description of the specific implementation

[0011] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the drawings.

[0012] Embodiment: A two-way pipe connector, as Figures 1 - 3As shown in the figure, it includes pipeline Ⅰ1, pipeline Ⅱ2 and connecting ring 3. Pipeline Ⅰ1 and pipeline Ⅱ2 are connected by connecting ring 3. The left end of pipeline Ⅰ1 is connected with connector Ⅰ1a. The inner diameter of connector Ⅰ1a is the same as that of pipeline Ⅰ1, and the outer diameter of connector Ⅰ1a is smaller than that of pipeline Ⅰ1. Wedge-shaped grooves Ⅰ1b are evenly spaced on the outer side surface of connector Ⅰ1a. The right end face of pipeline Ⅱ2 is connected with connector Ⅱ2a. The inner diameter of connector Ⅱ2a is the same as that of pipeline Ⅱ2, and the outer diameter of connector Ⅱ2a is smaller than that of pipeline Ⅱ2. Wedge-shaped grooves Ⅱ2b are evenly spaced on the outer side surface of connector Ⅱ2a. Wedge-shaped grooves Ⅰ1b and wedge-shaped grooves Ⅱ2b are symmetrically arranged with respect to the docking surface of pipeline Ⅰ1 and pipeline Ⅱ2. Wedge-shaped blocks Ⅰ3a are evenly spaced and installed on the right side inner wall of connecting ring 3, and wedge-shaped blocks Ⅱ3b are evenly spaced and installed on the left side inner wall of connecting ring 3. The inner diameter of connecting ring 3 is the same as the outer diameter of connector Ⅰ1a. A sealing ring 4 is sleeved on connector Ⅰ1a and connector Ⅱ2a through grooves. Pipeline Ⅰ1 is inserted into connecting ring 3 through connector Ⅰ1a, and wedge-shaped blocks Ⅰ3a in connecting ring 3 are stuck in wedge-shaped grooves Ⅰ1b. Pipeline Ⅱ2 is inserted into connecting ring 3 through connector Ⅱ2a, and wedge-shaped blocks Ⅱ3b in connecting ring 3 are stuck in wedge-shaped grooves Ⅱ2b.

[0013] When it is necessary to dock pipeline Ⅰ1 and pipeline Ⅱ2, first, sleeve sealing ring 4 on connector Ⅰ1a and connector Ⅱ2a, and then insert the ends of pipeline Ⅰ1 and pipeline Ⅱ2 with connector Ⅰ1a and connector Ⅱ2a into connecting ring 3. Wedge-shaped blocks Ⅰ3a and wedge-shaped blocks Ⅱ3b on connecting ring 3 are stuck in wedge-shaped grooves Ⅰ1b and wedge-shaped grooves Ⅱ2b on connector Ⅰ1a and connector Ⅱ2a. At the same time, because the left side of wedge-shaped block Ⅰ3a is a right-angle surface and the right side is an inclined surface, it can assist pipeline Ⅰ1 to be inserted into connecting ring 3. The left side of wedge-shaped groove Ⅰ1b is a right-angle surface and the right side is an inclined surface. After connector Ⅰ1a is inserted, wedge-shaped block Ⅰ3a is stuck in wedge-shaped groove Ⅰ1b, making pipeline Ⅰ1 unable to be pulled out. At the same time, because the left side of wedge-shaped block Ⅱ3b is an inclined surface and the right side is a right-angle surface, it can assist pipeline Ⅱ2 to be inserted into connecting ring 3. The left side of wedge-shaped groove Ⅱ2b is an inclined surface and the right side is a right-angle surface. After connector Ⅱ2a is inserted, wedge-shaped block Ⅱ3b is stuck in wedge-shaped groove Ⅱ2b, making pipeline Ⅱ2 unable to be pulled out. Sealing ring 4 can prevent liquid from flowing out through the gap when flowing through pipeline Ⅰ1 and pipeline Ⅱ2.
