Description

Technical Field

[0001] This utility model relates to the field of bimetallic composite pipes, and in particular to a novel corrosion-resistant bimetallic composite pipe. Background Technology

[0002] An existing patent (publication number: CN204647602U) proposes a pipe end connection structure for a bimetallic composite pipe, including a connecting sleeve with an inner diameter adapted to the outer diameter of the base pipe of the bimetallic composite pipe, and a sealing ring connected to the middle position inside the connecting sleeve; the two ends of the sealing ring are conical surfaces, the shape of which is consistent with the shape of the weld joint formed by the inner lining layer and the base pipe of the welded bimetallic composite pipe; the inner walls of the two ends of the connecting sleeve are provided with threads adapted to the outer wall of the base pipe of the bimetallic composite pipe at the connection point; the connecting sleeve and the composite pipe are connected by pipe threads to seal the weld joint at the pipe end with the sealing ring through the conical surface. However, in this device, the connecting sleeve is only fixedly connected to the composite pipe through the thread, and lacks a braking mechanism. As a result, when the threaded sleeve is accidentally touched or rotated due to other external forces, the composite pipes on both sides will loosen from it, affecting the stability and firmness of the connection between the pipes, which has drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a novel corrosion-resistant bimetallic composite pipe that is easy to operate. It allows for quick connection or disconnection of bimetallic composite pipes simply by rotating a turntable, eliminating the need for specialized tools or the individual disassembly and assembly of multiple bolts. This improves installation efficiency and facilitates subsequent maintenance. Furthermore, a braking component prevents the turntable from rotating due to accidental contact or other external forces, preventing loosening at the right flange threaded connection and ensuring the stability and firmness of the flange connection while maintaining good sealing to prevent leakage of the internal medium. Finally, an acrylic coating on the outside of the bimetallic composite pipe enhances its corrosion resistance and extends its service life.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel corrosion-resistant bimetallic composite pipe includes a bimetallic composite pipe, a sealing ring, a left flange, a right flange, a turntable, gear teeth, a locking sleeve, and threaded rods. The bimetallic composite pipe has an acrylic coating on the outside. The left end of the bimetallic composite pipe has a left flange, and the right end has a right flange. The left flange connects to the right flange to form a sealing groove, which is compatible with the sealing ring and connected to it. The left flange has multiple slots, and the right flange has multiple inserts, which are compatible with the slots and connected to them. The left flange has a mounting sleeve with a left baffle, and the right flange has a right baffle. The right baffle fits against the right side of the turntable, and the left side of the turntable fits against the left baffle. The right side of the turntable is threadedly connected to the right flange. The left side of the turntable has a rotating sleeve connected to the inside of an inner bearing, and the mounting sleeve is connected to the outside of the inner bearing.

[0006] The left baffle of this utility model has a fixed support plate, which is connected to the outside of the outer bearing. A threaded rod is connected inside the outer bearing. The upper end of the threaded rod has a knob, which fits into the fixed support plate. The lower end of the threaded rod is connected to a locking sleeve through a thread.

[0007] The lock sleeve of this utility model is attached to the outer side of the left baffle, and the gear disk is attached to the inner side of the left baffle. The gear disk has a shaft, which passes through the left baffle and the lock sleeve in sequence. The lock sleeve has a locking block, and the shaft has multiple locking grooves. The locking block is adapted to the locking grooves and is connected to the locking grooves. Beneficial effects

[0008] During installation of this utility model of bimetallic composite pipe, adjacent pipes are first placed concentrically, and the insert rod and right flange are respectively placed into the slot and turntable. Then, the turntable is rotated to tighten and fix it to the right flange through the thread until the right flange and left flange are tightly fitted. The sealing ring is embedded in the sealing groove to increase the sealing performance of the connection between the bimetallic composite pipes and prevent leakage of the medium transmitted in the pipe. Finally, the locking sleeve is moved by rotating the knob, and the locking block is embedded in the locking groove to lock the position of the shaft and gear disk. The turntable is braked and positioned by the meshing between the gear teeth and the tooth groove to prevent it from rotating due to accidental collision or other external forces, and to prevent it from loosening at the threaded connection with the right flange, thus ensuring the stability and firmness of the connection of the bimetallic composite pipe.

[0009] This utility model limits the assembly position of bimetallic composite pipes by inserting a plug into a slot, so that the right flange maintains linear displacement during the assembly and disassembly of the bimetallic composite pipe, avoiding its rotation due to the rotational force of the turntable, and also preventing axial rotation after the right flange contacts the left flange, thereby improving the stability of the connection between the right and left flanges and ensuring a tight fit between them.

[0010] This utility model is easy to operate. The bimetallic composite pipe can be quickly connected or disconnected by rotating the turntable without the need for special tools or disassembling and assembling multiple sets of bolts one by one. This improves the installation efficiency of the bimetallic composite pipe and facilitates disassembly and assembly work during later maintenance. By adding a braking component, the turntable is prevented from rotating due to accidental collision or other external forces, preventing it from loosening at the threaded connection with the right flange. This ensures the stability and firmness of the flange connection while providing good sealing performance to prevent leakage of the medium transmitted inside the pipe. Furthermore, the acrylic coating on the outside of the bimetallic composite pipe improves its corrosion resistance and extends its service life. Attached Figure Description

[0020] Example 1:

[0021] A novel corrosion-resistant bimetallic composite pipe includes a bimetallic composite pipe 01, a sealing ring 04, a left flange 07, a right flange 08, a turntable 11, a gear tooth 13, a locking sleeve 16, and a threaded rod 19. The bimetallic composite pipe 01 has an acrylic coating on its exterior. The left end of the bimetallic composite pipe 01 has a left flange 07, and the right end has a right flange 08. The left flange 07 connects to the right flange 08 to form a sealing groove 03, which is compatible with the sealing ring 04. The sealing groove 03 is connected to the sealing ring 04.

The inserts 05 are embedded in the slots 06 to protect the bimetallic composite pipe 01. The assembly position is limited so that when the bimetallic composite pipe 01 is disassembled and assembled, the right flange 08 maintains a linear displacement, avoiding its rotation due to the rotational force of the turntable 11, and also preventing axial rotation after the right flange 08 contacts the left flange 07, thus improving the stability of the connection between the right flange 08 and the left flange 07 and ensuring a tight fit between them. The left flange 07 has an installation sleeve 24 with a left baffle 23, and the right flange 08 has a right baffle 22. The right baffle 22 is attached to the right side of the turntable 11, and the left side of the turntable 11 is attached to the left baffle 23.

[0024] Example 3:

[0025] The locking sleeve 16 of this utility model fits against the outer side of the left baffle 23, and the gear disk 14 fits against the inner side of the left baffle 23. The gear disk 14 has a shaft 15, which passes through the left baffle 23 and the locking sleeve 16 in sequence. The locking sleeve 16 has a locking block 17, and the shaft 15 has multiple locking grooves 18. The locking block 17 is adapted to the locking grooves 18 and is connected to the locking grooves 18. When installing the bimetallic composite pipe 01, the adjacent pipes are first placed concentrically, and the insertion rod 05 and the right flange 08 are respectively placed into the slot 06 and the turntable 11. Then, the turntable 11 is rotated to tighten and fix it to the right flange 08 through the thread until the right flange 08 is tightened. 8 is tightly fitted with the left flange 07, and the sealing ring 04 is embedded in the sealing groove 03 to increase the sealing performance of the connection between the bimetallic composite pipes 01 and prevent leakage of the medium transmitted in the pipe. Finally, by rotating the knob 21, the locking sleeve 16 is moved to the position where the locking block 17 is embedded in the locking groove 18, locking the position of the shaft 15 and the gear disk 14. The gear teeth 13 mesh with the tooth groove 12 to brake and position the turntable 11, preventing it from rotating due to accidental contact or other external forces, and preventing it from loosening at the threaded connection with the right flange 08, thus ensuring the stability and firmness of the connection of the bimetallic composite pipes 01.

[0026] Example 4:

[0027] The gear disk 14 of this utility model fits onto the turntable 11. The turntable 11 has multiple toothed grooves 12, and the gear disk 14 has multiple gear teeth 13. The gear teeth 13 mesh with the toothed grooves 12 and connect to the toothed grooves 12. This device is easy to operate. By rotating the turntable 11, the bimetallic composite pipe 01 can be quickly connected or disconnected without the need for special tools or the need to disassemble and install multiple sets of bolts one by one. This improves the installation efficiency of the bimetallic composite pipe 01 and facilitates disassembly and assembly operations during later maintenance. By adding a braking component, the turntable 11 is prevented from rotating due to accidental contact or other external forces, preventing it from loosening at the threaded connection with the right flange 08. This ensures the stability and firmness of the flange connection while providing good sealing performance to prevent leakage of the medium transmitted inside the pipe. Furthermore, the acrylic coating on the outside of the bimetallic composite pipe 01 improves its corrosion resistance and extends its service life.
