Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, and in particular to a split-type pipe fitting for a large-diameter flexible composite high-pressure conveying pipe. Background Technology

[0002] High-pressure transmission pipe split-type pipe fittings are important equipment used to connect high-pressure transmission pipelines, commonly used in industries such as petroleum, natural gas, chemical, and power. Their main function is to connect two pipelines together, ensuring safe operation under high pressure, while facilitating pipeline maintenance and replacement. They are characterized by easy installation and disassembly. High-pressure transmission pipe split-type pipe fittings are crucial equipment for connecting high-pressure pipelines, designed with high sealing performance, easy disassembly and maintenance, and strong pressure resistance. They are widely used in industries such as petroleum, natural gas, chemical, and power, effectively ensuring the stable operation of pipeline systems and preventing leaks and accidents. Current split-type pipe fittings are generally designed to complete pipeline connection and installation, but various fixing methods exist. If threaded connections are used, the ease of assembly and disassembly cannot be achieved. However, current pipe fittings generally use threaded connections, flange connections, and compression fittings, which are not convenient for disassembly and assembly. Therefore, this utility model proposes a split-type pipe fitting that allows for unified control of disassembly and assembly in all directions, enabling rapid connection and disassembly of pipe fittings, eliminating tedious manual disassembly and assembly operations, and demonstrating strong practicality.

[0005] As a preferred embodiment, sealing rings are provided at both ends of the connecting body, and pipe one and pipe two are connected to the ends of the connecting body to achieve a seal.

[0006] As a preferred embodiment, the control mechanism includes a control gear rotatably mounted on the circumference of the connecting body, a control rod provided on the end face of the control gear, and a fixed shaft threadedly connected to both ends of the control rod, the fixed shaft being fixedly engaged with the outer side of the circumference of the connecting body.

Detailed Implementation

[0020] Example: Figures 1 to 6 As shown, the two ends of the connecting body 3 can be connected to pipe 1 and pipe 2, and connection holes are provided on the end faces of pipe 1 and pipe 2. Mounting shafts 5 are arranged in an array on the circumference of the connecting body 3, and the two ends of the mounting shafts 5 are locking mating ends 501. Locking mechanisms are also arranged in an array on the circumference of the connecting body 3. The locking mechanism includes mounting seats 8 fixedly set on the circumference of the connecting body 3. Locking plates 10 are telescopically set at both ends of the mounting seats 8. A flip seat 11 is rotatably set at one end of the locking plate 10. Locking holes 1101 are arranged on the flip seat 11. Pipe 1 and pipe 2 are respectively connected to the two ends of the connecting body 3, and the connection holes on pipe 1 and pipe 2 engage with the locking mating ends 501, so that the flip seat 11 is flipped and the position of the locking plate 10 is adjusted so that the locking holes 1101 engage with the locking mating ends 501, so as to lock and fix pipe 1 and pipe 2 to the two ends of the connecting body 3. A control mechanism is also provided on the circumference of the connecting body 3 for adjusting and controlling the locking mechanism.

[0021] Sealing rings 4 are provided at both ends of the connecting body 3. Pipe 1 and pipe 2 are connected to the ends of the connecting body 3 to achieve a seal.

[0022] The control mechanism includes a control gear 16 rotatably mounted on the circumference of the connecting body 3. A control rod 17 is provided on the end face of the control gear 16. The two ends of the control rod 17 are threadedly connected to a fixed shaft 18, which is fixedly engaged with the outer circumference of the connecting body 3. A fixing hole 301 is provided on the outer circumference of the connecting body 3, which engages with the fixed shaft 18 for fixation. The control mechanism also includes a limiting wheel 6 mounted on the mounting shaft 5. A control gear ring 7 is rotatably mounted on the limiting wheel 6, and the end face of the control gear 16 meshes with the control gear ring 7. The control gear ring 7 is used to drive the locking plate 10 on the locking mechanism to move.

[0023] The locking mechanism includes a telescopic shaft 9 and a telescopic screw 12 connected to the locking plate 10. The telescopic shaft 9 and the telescopic screw 12 are telescopically connected to the mounting base 8. A connecting gear 13 is rotatably mounted on the mounting base 8. The connecting gear 13 and the telescopic screw 12 form a helical pair. The connecting gear 13 meshes with the circumference of the control gear ring 7. A pressure plate 14 is slidably disposed on the end face of the connecting body 3 and on the locking mating end 501. A spring 15 is connected between the pressure plate 14 and the end face of the connecting body 3.

[0024] The operating principle is as follows: Pipe 1 and Pipe 2 are respectively connected to the two end faces of the connecting body 3, and the connecting holes on Pipe 1 and Pipe 2 mate with the locking end 501. At this time, the flipping seat 11 is in an upward flipped state, that is, the flipping seat 11 and the locking plate 10 are in a horizontal state. After Pipe 1 and Pipe 2 are connected to the end faces of the connecting body 3, the flipping seat 11 is flipped downward, so that the flipping seat 11 is in a vertical state. By rotating the control gear 16 and the control rod 17, under the gear transmission, the control gear... When ring 7 rotates, the connecting gear 13 rotates. Under the connection of the screw pair, the telescopic screw 12, telescopic shaft 9 and locking plate 10 move, causing the flip seat 11 to move. The locking hole 1101 engages with the locking mating end 501, so the flip seat 11 can restrict and fix pipe 1 and pipe 2 to the end face of the connecting body 3. Furthermore, the end faces of pipe 1 and pipe 2 contact the pressure plate 14. When pipe 1 and pipe 2 are pressed, the spring 15 is compressed, and the elastic force provided by the spring 15 can increase the locking force.

[0025] After locking is completed, the fixed shaft 18 can be inserted into the fixed hole 301 to form a fit, thereby restricting the rotational freedom of the control gear 16 and the control rod 17, and further restricting the freedom of the control gear ring 7 and the connecting gear 13 to achieve stability.

[0026] Furthermore, when pipe 1 and pipe 2 are in contact with the end face of the connecting body 3, the sealing ring 4 is located inside pipe 1 and pipe 2 to achieve a sealing operation; during disassembly, the locking plate 10 is adjusted by reversing the operation, that is, by adjusting the control gear 16 and the control rod 17, so that the flip seat 11 is disengaged from the locking engagement end 501, thereby releasing the restriction on pipe 1 and pipe 2 and completing the disassembly. The operation is convenient and efficient.
