Description

Technical Field

[0001] This invention relates to the field of pipe fittings, and more specifically to a combined quick coupling. Background Technology

[0002] When a branch pipe needs to be connected to a main pipe, the traditional method is to drill holes in the main pipe and weld the branch pipe. This method is inconvenient to construct and cannot be disassembled. Therefore, quick couplings are now widely used for connection. Quick couplings are plug-and-play and provide quick and convenient pipe connection, and are widely used for connecting fluid pipelines such as compressed air, inert gas, water, and oil.

[0003] Existing technologies, such as the clamp-type quick coupling disclosed in Chinese patent CN205101739U, feature rapid installation and disassembly. However, the connector pipe connecting the quick coupling to the branch pipeline is usually integrally cast or welded onto the clamp seat. If a branch pipeline of a different diameter needs to be replaced, the entire quick coupling needs to be replaced. Furthermore, the diameter of the insertion port of the replacement quick coupling does not match the hole on the original pipeline, requiring re-drilling, which is very inconvenient and indicates room for improvement. Summary of the Invention

[0004] The purpose of this invention is to propose a combined quick coupling, in which the coupling seat and branch pipe are combined and modular, solving the problem that current quick couplings are inconvenient to change the diameter of branch pipes.

[0005] A modular quick coupling includes: a coupling seat, the coupling seat having a clamp-type structure, the coupling seat having a mounting base, the mounting base having a mounting groove below it, the mounting base having a connection hole, and the coupling seat having bosses on both sides, with threaded holes on the bosses;

[0006] A connector pipe has branch pipes, one end of which is fixedly connected to a connecting platform, the other end of which is fixedly connected to a mounting platform, and the other end of which is fixedly connected to a plug interface. The mounting platform mates with a mounting groove, and the connecting platform mates with a connecting hole.

[0007] The connector seat and the connector tube are detachably connected.

[0008] Preferably, the two fittings are mated on the pipe and fastened together using bolts through threaded holes.

[0009] Preferably, the outer diameter of the connecting platform on the connector is the same as the diameter of the connecting hole on the connector seat, and the diameter of the branch pipe on the connector pipe is smaller than the diameter of the connecting platform.

[0010] Preferably, there are multiple sets of connector pipes, and each set contains several connector pipes. The diameters of the branch pipes in each set are different. Although the diameters of the branch pipes are different, the other dimensions are the same, and all can be installed on the connector seat. When the diameter of the branch pipe needs to be changed, only the connector needs to be replaced.

[0011] Preferably, the mounting platform and the mounting groove are provided with screw holes at the same position as the axis of the connector pipe. The screw passes through the screw hole from one side of the mounting platform to secure the mounting platform to the mounting groove. The connector seat presses the mounting platform on the connector pipe tightly onto the pipe, and the screw is held in place by the pipe, preventing the screw from loosening and falling off due to vibration, thus preventing the connector pipe from falling off.

[0012] Preferably, a sealing groove is provided at the connection point between the branch pipe mounting platform and the insertion interface, and a sealing ring is provided in the sealing groove.

[0013] More preferably, the sealing ring is a saddle-shaped sealing ring, which can effectively seal the pipe connection.

[0014] Preferably, the connector seat is prepared by an aluminum alloy extrusion molding process, which includes the following steps: (1) homogenization treatment; (2) extrusion molding; (3) quenching; and (4) aging treatment.

[0015] More preferably, the homogenization treatment is carried out at a temperature of 510-520℃ for 4-6 hours.

[0016] More preferably, the homogenization treatment is carried out at a temperature of 515°C for 5 hours.

[0017] Preferably, a secondary processing is required after the homogenization process.

[0018] More preferably, the secondary processing step involves treating the surface of the homogenized aluminum alloy ingot with a rotating wire brush.

[0019] Preferably, the extrusion ratio in the extrusion molding step is 40-45, and the extrusion speed is 3-5 m / min.

[0020] More preferably, the extrusion ratio in the extrusion molding step is 40-42, and the extrusion speed is 3.7-4.7 m / min.

[0021] More preferably, the extrusion ratio in the extrusion molding step is 40.8 and the extrusion speed is 4.2 m / min.

[0022] Preferably, in the quenching step, the temperature of the aluminum alloy profile entering the quenching zone is 480-520℃, and the temperature exiting the quenching zone is 90-110℃.

[0023] More preferably, in the quenching step, the temperature of the aluminum alloy profile entering the quenching zone is 490-510℃, and the temperature exiting the quenching zone is 100-110℃.

[0024] More preferably, in the quenching step, the temperature of the aluminum alloy profile entering the quenching zone is 500°C, and the temperature exiting the quenching zone is 105°C.

[0025] The applicant discovered that homogenizing the aluminum alloy substrate followed by high-speed rotating wire brush treatment significantly improves the gloss of the aluminum alloy profile. This may be because homogenizing the aluminum alloy substrate results in a more uniform distribution of various solute elements within the crystals of the ingot. The high-speed rotating wire brush treatment removes adhering dust and impurities from the aluminum alloy surface, thereby reducing the likelihood of gloss reduction during subsequent extrusion. Based on this, while ensuring the gloss of the aluminum alloy substrate, the mechanical properties of the aluminum alloy are further improved. The applicant limits the extrusion ratio to 40-42 and the extrusion speed to 3.7-4.7 m / min, which improves the mechanical properties of the aluminum alloy substrate. As the extrusion ratio increases, the particle size of the aluminum alloy gradually decreases, and the density of the reinforcing phase gradually increases and the distribution becomes more uniform. The tensile strength of the aluminum alloy increases, but the yield strength tends to decrease. After consideration, the applicant limits the temperature of the aluminum alloy profile entering the quenching zone to 490-510℃ and the temperature exiting the quenching zone to 100-110℃. Unexpectedly, it was found that not only did the yield strength increase, but the tensile strength of the aluminum alloy also increased to a certain extent. This may be due to the small and uniform grains in the aluminum alloy and the sufficient solid solution of the reinforcing phase, thereby improving the mechanical properties of the aluminum alloy.

[0026] Beneficial effects:

[0027] 1. This invention provides a modular quick coupling, in which the coupling seat and the coupling pipe are combined and the coupling pipe is modularized, so as to achieve the purpose of quickly changing the diameter of the branch pipe. At the same time, the manufacturing process of the quick coupling is simpler, which greatly saves production costs.

[0028] 2. In ordinary quick couplings, the branch pipe is integrally cast or welded to the coupling seat. If the diameter of the branch pipe needs to be changed, the entire quick coupling needs to be replaced, and the hole on the pipe will also be incompatible, requiring re-drilling. The modular quick coupling in this invention only requires replacing the coupling pipe. Different coupling pipes have different branch pipe diameters, but all other dimensions are the same, allowing for quick replacement. The hole size on the pipe is the same as the insertion interface of the coupling, eliminating the need to re-drill holes in the pipe.

[0029] 3. The combination structure of the connector pipe and connector seat may cause unstable connection and connector pipe detachment due to pipeline vibration. In this invention, the connector seat presses the mounting platform on the connector pipe tightly onto the pipeline, and the screws connecting the mounting platform and the mounting groove are held in place by the pipeline. The screws will not loosen or fall off due to vibration, thus preventing the connector pipe from falling off.

[0030] 4. The connector seat prepared by the aluminum alloy extrusion molding process of this invention has excellent tensile strength and yield strength. In addition, its gloss is also greatly improved, which broadens its application in various fields. Attached Figure Description

[0040] Example 1

[0041] To quickly replace branch pipes of different diameters without having to drill new holes in the existing pipes, a solution is provided, such as... Figure 1-4 The combined quick coupling shown includes: a coupling seat 1, which is a clamp-type structure, a mounting seat 11 on the coupling seat 1, a mounting groove 12 below the mounting seat 11, a connection hole 13 on the mounting seat 1, and bosses 14 on both sides of the coupling seat 1, with threaded holes 15 on the bosses 14.

[0042] The connector pipe 2 has a branch pipe 21. One end of the branch pipe 21 is fixedly connected to a connecting platform 22, and the other end of the connecting platform 22 is fixedly connected to a mounting platform 23. The other end of the mounting platform 23 is fixedly connected to a plug interface 24. The mounting platform 23 mates with the mounting groove 12, and the connecting platform 22 mates with the connecting hole 13.

[0043] The connector seat 1 and the connector tube 2 are detachably connected.

[0044] Two connector seats 1 are mated together on the pipe and fastened using bolts through threaded holes 15. The double-sided bolt fastening connection distributes the force evenly, preventing bolt breakage.

[0045] The outer diameter of the connecting platform 22 on the connector pipe 2 is the same as the diameter of the connecting hole 13 on the connector seat 1. The diameter of the branch pipe 21 on the connector pipe 2 is smaller than the diameter of the connecting platform 22. The diameters of the connecting platform 22 and the connecting hole 13 are 120mm.

[0046] like Figure 2 As shown, a set of modular quick couplings includes two coupling seats and five sets of coupling tubes 2. Each set has two coupling tubes 2. The diameters of the branch pipes 21 on the five sets of coupling tubes 2 are 100mm, 80mm, 65mm, 50mm, and 40mm, respectively. The diameters of the branch pipes 21 of the coupling tubes 2 are different, but the other dimensions are the same, and all can be installed on the coupling seat 1. When it is necessary to change the diameter of the branch pipe, only the coupling tube 2 needs to be replaced. The diameter of the insertion interface 24 is 100mm. After drilling a hole in the pipe, each coupling tube 2 can be adapted, and it is not necessary to re-drill holes in the pipe to replace the coupling tube 2.

[0047] The mounting platform 23 and the mounting groove 12 are provided with screw holes 25 at the same position as the axis of the connector pipe 2. The screw passes through the screw hole 25 from one side of the mounting platform 23 to fasten the mounting platform 23 to the mounting groove 12. The connector seat 1 presses the mounting platform 23 on the connector pipe 2 onto the pipe. The screw is held in place by the pipe and will not loosen or fall off due to vibration, thus preventing the connector pipe 2 from falling off.

[0048] There is a sealing groove 26 at the connection between the branch pipe 21 mounting platform 23 and the insertion interface 24. A sealing ring 3 is installed in the sealing groove 26. The sealing ring 3 is a saddle-shaped sealing ring, which can effectively seal the pipe connection.

[0049] like Figure 5 As shown, the connector 1 is made of aluminum alloy through integral extrusion molding, and then cut to the appropriate width as needed. Compared with the traditional casting process, it has higher processing efficiency and lower cost.

[0053] (2) Extrusion molding;

[0057] (4) Time-sensitive processing.

[0058] The quenched aluminum alloy profile is subjected to aging treatment at a temperature of 170℃ for 8 hours to obtain the final product.

[0059] The aluminum alloy ingot was purchased from Dongguan Quntong Metal Technology Co., Ltd., model number 1050. The main components of the aluminum alloy ingot include aluminum (Al≥99.50), silicon (Si≤0.25), copper (Cu≤0.05), magnesium (Mg≤0.05), zinc (Zn≤0.05), manganese (Mn≤0.05), titanium (Ti≤0.03), vanadium (V≤0.05), and iron (Fe 0.000-0.400).
