Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, and particularly relates to a copper-nickel sleeve for ships. Background Art

[0002] Since the use scenario of a ship is a water environment, the probability that the pipe fittings on the ship are adhered to and immersed in water is relatively high. In order to extend the service life of the pipe fittings, copper-nickel pipe fittings with high corrosion resistance are generally selected to reduce the corrosion and damage speed of the pipe fittings.

[0003] The shapes of traditional copper-nickel pipe fittings are fixed. When the pipes to be connected change, it is often difficult to adapt to the new installation requirements. Generally, the pipe fittings need to be removed and reinstalled, and additional new connectors are needed to connect the new pipes and the pipe fittings, resulting in difficulties in reducing the workload and cost of changing the pipeline of the pipe fittings. Content of the Utility Model

Sliders 10 corresponding to the linear chutes 8 are provided on the outer wall of the inner straight pipe 2. The sliders 10 are at the same height on the inner straight pipe 2. The sliders 10 can slide in the linear chutes 8 and the annular chute 9. The sliders 10 can enter and exit the linear chutes 8 from the openings at the lower ends of the linear chutes 8, and the sliders 10 can enter and exit the annular chute 9 from the communication points between the linear chutes 8 and the annular chute 9. Locking components 11 are evenly provided along the circumference at the top of the outer sleeve 1. The locking components 11 are used to control the ability of the inner straight pipe 2 to move relative to the outer sleeve 1.

[0023] Without completely reinstalling and disassembling and without additionally supplementing connecting parts, the height and orientation of the upper port of the connector 3 can be flexibly adjusted, enabling the upper port of the connector 3 to be specifically changed according to the changes of the pipe fittings to be connected, thus completing the diversion operation; when adjusting the position of the upper port of the connector 3, first adjust the orientation and then the height. By the combined use of the slider 10, the linear chute 8 and the annular chute 9, first let the slider 10 rise into the annular chute 9 along the linear chute 8, and then let the slider 10 slide along the annular chute 9 to rotate the inner straight pipe 2 around its central axis, thereby adjusting the orientation of the upper port of the connector 3 connected to the inner straight pipe 2. After the upper port of the connector 3 is turned to the correct orientation, lower the slider 10 into the correctly positioned linear annular groove, and then by the combined use of the slider 10 and the linear chute 8, let the slider 10 move along the linear chute 8, thereby adjusting the height of the inner straight pipe 2 and the upper port of the connected connector 3. After the position of the upper port of the connector 3 is adjusted, the inner straight pipe 2 and the connector 3 connected to the inner straight pipe 2 are fixed at the current position through the locking assembly 11. The outer sleeve 1, the inner straight pipe 2 and the connector 3 are convenient to assemble and disassemble, improving the installation efficiency of the staff; during assembly, the sealing ring A7 is installed in the installation groove 6 at the upper port of the outer sleeve 1, and then the inner straight pipe 2 is inserted into the outer sleeve 1 with the slider 10 aligned with the linear chute 8, so that the upper port of the inner straight pipe 2 extrudes from the inner ring of the sealing ring A7 out of the outer sleeve 1, fix the inner straight pipe 2 with the locking assembly 11, and connect the lower port of the connector 3 to the upper port of the inner straight pipe 2. When disassembling, first disconnect the connection between the connector 3 and the inner straight pipe 2, then unlock each locking assembly 11, and finally pull out the inner straight pipe 2 from the outer sleeve 1.

[0024] Further, the locking assembly 11 includes a fixing plate 12, a threaded rod 13 and a turning handle 14. The fixing plates 12 are evenly arranged along the circumference at the top of the outer sleeve 1.

[0025] When it is necessary to fix the position of the inner straight pipe 2, the staff holds the turning handle 14 and rotates the threaded rod 13 to screw the threaded rods 13 at each place into the opposite sockets 16. When it is necessary to move and rotate the inner straight pipe 2, pull out the threaded rod 13 from the socket 16. In order to avoid leakage problems at the gap between the sealing ring A7 and the inner straight pipe 2, the size of the socket 16 is smaller than the thickness of the sealing ring A7.

[0026] Further, an extension ring 17 is provided along the inner edge of the upper port of the inner straight pipe 2. Threaded holes 18 are evenly arranged along the circumference at the top of the extension ring 17. A groove 21 corresponding to the threaded hole 18 is provided on the side wall of the connecting head 3. A threaded through hole B19 corresponding to the threaded hole 18 is provided at the bottom of the groove 21. The detachable connection between the connecting head 3 and the inner straight pipe 2 is realized by screwing a fixing screw 22 into the overlapping threaded hole 18 and threaded through hole B19.

[0027] The inner straight pipe 2 and the connecting head 3 are connected by the fixing screw 22, with firm connection and convenient operation.

[0028] Further, the number of the straight chutes 8 is four.

[0030] The sealing performance between the upper port of the inner straight pipe 2 and the lower port of the connecting head 3 is improved through the sealing ring B20, reducing the leakage risk.

[0031] The working principle and usage process of the present utility model:

[0032] During the initial installation, first install the inner straight pipe 2 on the outer sleeve pipe 1, then install the connecting head 3 on the inner straight pipe 2, and finally connect the outer sleeve pipe 1 and the connecting head 3 to the ports of their respective corresponding pipes.

[0033] When the pipe to which the connecting head 3 needs to be connected changes, first separate the connecting head 3 from the original pipe, then unlock each locking component 11 to enable the inner straight pipe 2 to regain its moving ability. First, lift the inner straight pipe 2 to let the slider 10 enter the annular chute 9, then turn the upper port of the connecting head 3 to face the new pipe, then let the slider 10 fall into the corresponding straight chute 8, align the upper port of the connecting head 3 with the port of the new pipe, and finally close each locking component 11 again to fix the position of the inner straight pipe 2, and connect the upper port of the connecting head 3 to the port of the new pipe to complete the pipe changing operation.

[0034] The above is only a specific application example of the present utility model, which does not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the rights protection of the present utility model.
