Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] EMBODIMENT
[0027] As Figures 1-4 shown in the utility model one embodiment presents multifunctional metal pipeline connecting device, including connecting piece 1, opposite pipeline 2 is inserted and welded fixedly in connecting piece 1, insertion hole 3 is set up on connecting piece 1, and fastening screw 4 is installed in insertion hole 3, mounting piece 5 is threadedly connected on fastening screw 4, cushion block 6 is installed on fastening screw 4, fastening nut 7 is installed on cushion block 6, the bottom of connecting piece 1 is circular, and sawtooth groove 8 is arranged on the circular, and the sawtooth grooves 8 on the two connecting pieces 1 are engaged with each other.
[0028] Connecting piece 1 is in a specific shape as a whole, and is used for accommodating opposite pipeline 2 inside, and the bottom is circular and has sawtooth groove 8, and insertion hole 3 is set up on the top.
[0029] It is the main structure of the whole connecting device, provides the installation basis of each component, and the sawtooth grooves 8 on the bottom are engaged with each other, so that the stability and positioning accuracy when the two connecting pieces 1 are connected can be enhanced, and the overall structure after connection is ensured to be firm; the internal space is used for fixing opposite pipeline 2, so that the pipeline connection is more stable; insertion hole 3 provides a position for the installation of fastening screw 4, so as to realize further fastening and sealing functions.
[0030] Opposite pipeline 2 is a pipeline made of metal material, which can be fixed with connecting piece 1 in a certain mode.
[0031] It is a channel for conveying fluid, which is placed at any angle in connecting piece 1 and connected, so that the communication of pipelines in different directions is realized, the complex pipeline layout requirements are met, and the transmission of fluid between different pipelines is ensured.
[0032] Insertion hole 3 is set up on connecting piece 1, and the shape and size are matched with fastening screw 4.
[0033] The installation of the fastening screw 4 provides a channel, so that the fastening screw 4 can pass through the connecting piece 1, cooperate with other components to realize the fastening of the connecting piece 1 and the opposite pipe 2, and is also a key part for the sealing function of the mounting piece 5.
[0034] The fastening screw 4 is an elongated rod with threads, which passes through the insertion hole 3 of the connecting piece 1.
[0035] As the main fastening component, the fastening screw 4 is connected with the mounting piece 5 through threads and cooperates with the fastening nut 7 to apply a fastening force to the connecting piece 1 and the opposite pipe 2 to prevent the pipe from loosening; the length and diameter design can meet the requirements of fastening degree under different working conditions, and ensure the stability of the pipe connection under the condition of bearing fluid pressure.
[0036] The mounting piece 5 has the same diameter as the insertion hole 3 and has a thread structure matched with the fastening screw 4.
[0037] The mounting piece 5 is installed on the fastening screw 4 and located at the insertion hole 3 of the connecting piece 1, and seals the insertion hole 3 through the same diameter as the insertion hole 3 to prevent fluid leakage from the insertion hole 3 and ensure the sealing of the pipe system; at the same time, the threaded connection facilitates cooperation with the fastening screw 4, and plays a role in adjusting the sealing degree and fastening force during the fastening process.
[0038] The pad 6 is shaped to fit the connecting piece 1 and is installed on the fastening screw 4 between the connecting piece 1 and the fastening nut 7.
[0039] During the fastening process, the shape of the pad 6 fits the connecting piece 1 to better transmit the fastening force of the fastening nut 7, so that the fastening force is evenly distributed on the connecting piece 1, enhancing the fastening effect; at the same time, it plays a role in buffering and protecting the surface of the connecting piece 1, preventing the fastening nut 7 from directly contacting the connecting piece 1 and causing damage, and ensuring the structural integrity and service life of the connecting piece 1.
[0040] The fastening nut 7 has threads inside and is matched with the fastening screw 4, and is installed on the pad 6.
[0041] Through the threaded connection with the fastening screw 4, pressure is applied to the pad 6 when tightening, so that the connection between the connecting piece 1 and the opposite pipe 2 is more tight; the fastening degree can be adjusted according to actual needs to adapt to different working conditions and pipe pressure requirements, ensuring the reliability and stability of the connecting device.
[0042] The sawtooth groove 8 is provided at the bottom of the connecting piece 1 and is tooth-shaped.
[0043] When the two connecting pieces 1 are connected, the sawtooth grooves 8 are engaged with each other, which can increase the friction and connection strength between the connecting pieces 1, prevent the connecting pieces 1 from rotating or moving relative to each other when subjected to force, further improve the stability of the entire connecting device, and ensure that the pipeline connection remains in a reliable connection state under various working conditions.
[0044] The working principle of the multifunctional metal pipeline connecting device is as follows: first, insert the opposite pipeline 2 into the connecting piece 1 and perform plug-in welding to fix the opposite pipeline 2, so that the opposite pipeline 2 is stably connected in the connecting piece 1. Then, pass the fastening screw 4 through the plug-in hole 3 of the connecting piece 1, install the gasket 6 and the fastening nut 7 on the fastening screw 4 in sequence, and threadedly connect the mounting piece 5 with the fastening screw 4, and the diameter of the mounting piece 5 is the same as that of the plug-in hole 3 to achieve sealing. During installation, by tightening the fastening nut 7, the fastening nut 7 exerts pressure on the gasket 6, and the gasket 6 uniformly transmits the force to the connecting piece 1, so that the connection between the connecting piece 1 and the opposite pipeline 2 is more compact. At the same time, the sawtooth grooves 8 at the bottom of the two connecting pieces 1 are engaged with each other, further enhancing the stability of the connection between the connecting pieces 1 and preventing relative movement. When it is necessary to repair or replace the pipeline, the above steps are reversed to quickly disassemble the connecting device. Through the cooperation of various components, the device realizes the firm connection, sealing, and quick disassembly and installation of the metal pipeline, effectively solves the problems existing in the traditional connection method, and meets the use requirements under complex pipeline layout and different working conditions.
[0045] As shown in Figure 2 In some embodiments, the diameter of the mounting piece 5 is the same as the shape and size of the plug-in hole 3, which is sealed. This design enables the mounting piece 5 to completely fill the plug-in hole 3, thereby blocking the leakage path of the fluid through the plug-in hole 3.
[0046] As shown in Figure 2 In some embodiments, the shape of the gasket 6 matches the shape of the connecting piece 1; that is, the outer contour of the gasket 6 can closely fit the part of the connecting piece 1 in contact. This fit is not a simple contact, but a high degree of matching in shape, so that the gasket 6 can completely cover the area of the connecting piece 1 that needs to function, and maintain consistent contact with the connecting piece 1 in all directions.
[0047] As shown in Figure 2 In some embodiments, the fastening nut 7 on the gasket 6 is threadedly connected with the fastening screw 4 to fasten the gasket 6; when the fastening nut 7 is tightened clockwise, due to the action of the thread, the fastening nut 7 will move along the fastening screw 4 in the direction of the connecting piece 1, thereby exerting pressure on the gasket 6 located below. This pressure is uniformly transmitted to the connecting piece 1 through the gasket 6, making the connection between the connecting piece 1 and the opposite pipeline 2 more compact, and ensuring the stability of the pipeline connection.
[0048] As Figure 4 shown, in some embodiments, two said opposite pipes 2 are connected by being placed at any angle in the connector 1; the connector 1 provides sufficient space inside so that the opposite pipes 2 can be freely adjusted within a certain range of angles. At the same time, through the fixed mode of plug welding, the opposite pipes 2 can be firmly combined with the connector 1 after being adjusted to the required angle, ensuring the stability of the connection.
[0049] The connecting device can be quickly disassembled and installed, facilitating the maintenance and replacement of the pipes; compared with some traditional connection methods, only the opposite pipes 2 and the connector 1 in the device are fixed by plug welding, and the number of welding points is less. When the pipes are maintained or replaced, a large number of complex welding parts do not need to be processed, greatly saving time and workload. Moreover, this relatively simple welding method not only ensures the firmness of the connection, but also facilitates the separation operation when necessary.
[0050] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
