Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a flared clamp type pipeline connector. Background Art

[0002] The flared pipe fitting is also called a flared fitting. The end of the pipe is flared to form an inverted cone-shaped fitting. When connecting, the flared part is directly inserted into the connection port of another pipe or fitting and fixed with fasteners. Flared pipe fittings are usually used for the transmission of low and medium pressure liquids or gases. They have good sealing and connection strength. Flared pipe fittings are widely used in high-pressure pipeline applications in the industrial field, such as ships, offshore oil, metal processing and mining, etc.

[0003] The flared joint is made of forgeable cast iron or ductile iron as the main material, and consists of an inner liner pipe body (bushing), nuts or bolts, threaded rings or flared flanges, and sealing rubber rings. The sealing rubber rings are compressed by tightening the nuts or flanges to achieve an oblique side seal between the inner surface of the pipe and the sealing rubber ring on the inner liner pipe body. It is a simple metal pipe connection.

[0004] Conventional pipe connectors need to be sleeved on one end of the pipe connection during use. Due to the split structure during docking installation, the assembly installation process is relatively time-consuming and labor-intensive, affecting the installation efficiency. At the same time, the connection structure of the pipe connector is simple and is easily deformed due to external forces, which poses a risk of leakage to a certain extent.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a flared clamp type pipe connector is proposed. Utility Model Content

[0015] The utility model provides a flared clamp type pipe connector, which has the following beneficial effects:

[0016] 1. The utility model, by installing docking frames on the middle sections of the first connecting pipe and the second connecting pipe respectively, and utilizing the structure of the docking plug and the external sleeve, the pipes can be installed in two ways during docking installation. When the diameter of the pipe is smaller than the docking plug, it can be inserted into the interior of the docking plug by horizontal insertion, so as to facilitate subsequent pipe docking. When the pipe is larger than the outer diameter of the docking plug and smaller than the inner diameter of the external sleeve, the pipe can be inserted between the docking plug and the external sleeve along the horizontal direction to perform pipe docking. By utilizing the above structure, the entire structural member can have good flexibility in use to a certain extent. In addition, a cross-shaped groove is provided on the top of the fastening bolt used to connect and fix the first connecting pipe and the second connecting pipe, so that when the fastening bolt is screwed, different tools can be selected for screwing and fixing according to the installation operation, thereby improving the flexibility and convenience of the device structure combination.

In addition, adjusting bolts are threadedly penetrated around the external sleeve, and a sealing gasket with an arc structure is connected to the end of the adjusting bolt. By screwing the adjusting bolt, the sealing gasket connected to it is pressed against the outer wall surface of the pipe, so that the pipe sleeved on the outer wall of the docking plug and located in the external sleeve can be clamped and fixed around. Under the action of the sealing ring, the sealing and structural firmness of the pipe connection structure can be further achieved at the same time, so as to avoid the problem of structural loosening and leakage. The use of the fastening ring can effectively ensure the stability and tightness of the connection between the main frame and the expanded clamping pipe structure, and further avoid the occurrence of structural loosening.

[0018] 3.

By using the above structure, on the one hand, the structural disassembly and assembly of the first connecting tube and the second connecting tube can have structural stability in the horizontal direction, which is convenient for the disassembly and assembly of the structure, so that the efficiency of structural docking can be effectively improved, and structural dislocation during the docking process can be avoided to affect the installation efficiency. On the other hand, the use of the above structure can provide effective structural reinforcement around the connection between the first connecting tube and the second connecting tube to form a frame structure, which can avoid structural deformation of the connection between the first connecting tube and the second connecting tube due to external force to a certain extent, thereby causing leakage problems, so that the stability and safety of the entire structure are effectively improved.

The sealing ring 404 is arranged in a quarter arc structure. The second connecting pipe 2 and the first connecting pipe 1 adopt the same structural arrangement, and the fastening bolt 3 is threadedly connected to the second connecting pipe 2 and the first connecting pipe 1, and a cross groove structure is provided on the top of the fastening bolt 3. By using the structure of the docking plug 103 and the external sleeve 402, there are two installation methods for the pipeline during docking installation. When the diameter of the pipeline is smaller than the docking plug 103, it can be inserted into the interior of the docking plug 103 by horizontal insertion to facilitate subsequent pipeline docking. When the pipeline is larger than the outer diameter of the docking plug 103 and smaller than the inner diameter of the external sleeve 402, the pipeline can be docked by inserting the pipeline horizontally between the docking plug 103 and the external sleeve 402.

[0026] like Figures 1 to 4 As shown, the first connecting pipe 1 includes a flared clamping tube 101, a docking flange 102, a docking plug 103 and a sealing gasket 104. The docking flange 102 is provided at one end of the flared clamping tube 101, and the docking plug 103 is provided at the end of the docking flange 102 away from the docking flange 102, and the surface of the docking plug 103 is covered with a sealing gasket 104. The flared clamping tube 101, the docking flange 102 and the docking plug 103 are arranged in an integrated structure, and the sealing gasket 104 covers the inner and outer surfaces of the docking plug 103. The adjusting bolts 403 are threadedly penetrated around the external sleeve 402, and the sealing gasket 104 with an arc structure is connected to the end of the adjusting bolt 403.

[0027] like Figures 1 to 4As shown, the fastening ring 405, the sealing ring 404 and the sealing gasket 104 are all made of the same material, and the fastening ring 405 is arranged at the junction of the main frame 401 and the flared clamping tube 101 with an interference structure, the guide bracket 5 slides through the upper and lower sides of the main frame 401, and the two-way worm 6 is threadedly connected to the main frame 401, the guide bracket 5 and the two-way worm 6 are parallel to each other, and the guide bracket 5 and the two-way worm 6 are respectively arranged at the four diagonals of the main frame 401, and the guide bracket 5 and the two-way worm 6 are arranged on the upper and lower sides of the docking frame 4, so that the left and right symmetrically arranged docking frame 4 has good structural integrity under the structural connection of the guide bracket 5 and the two-way worm 6, and when the two-way worm 6 is rotated horizontally axially, the left and right docking frames 4 can simultaneously perform left and right translation adjustment in the horizontal direction along the surfaces of the guide bracket 5 and the two-way worm 6.

[0029] Then, the connection method between the pipeline and the first connecting pipe 1 and the second connecting pipe 2 is selected according to the use needs. When the diameter of the pipeline is smaller than the docking plug 103, it can be inserted into the interior of the docking plug 103 by horizontal insertion to facilitate the subsequent pipeline docking. When the pipeline is larger than the outer diameter of the docking plug 103 and smaller than the inner diameter of the external sleeve 402, the pipeline can be docked by inserting the pipeline between the docking plug 103 and the external sleeve 402 in the horizontal direction. In this process, no matter which docking method is used, the sealing gasket 104 provides good structural sealing and insertion firmness between the pipeline and the docking plug 103. In addition, when the second connection method is selected, it is only necessary to screw the adjusting bolt 403 set on the outside of the external sleeve 402 and press the sealing ring 404 connected to its structure against the surface of the pipeline.

[0030] Then, by rotating the bidirectional worm gear 6, the first connecting pipe 1 and the second connecting pipe 2 with the pipes inserted will be translated in the horizontal direction toward the vertical central axis position of the guide bracket 5 until the structure is docked. Finally, it is only necessary to use the fastening bolts 3 to horizontally screw into the docking flanges 102 in the first connecting pipe 1 and the second connecting pipe 2 to complete the installation and fixation of the structure.
