Technical Field

[0001] The present application relates to the technical field of joints, and more specifically, to a high temperature resistant quick joint. Background Art

[0002] A quick connector is a connector that can connect or disconnect pipes without the need for tools. Quick connectors can be roughly divided into quick connectors for air, quick connectors for oxygen and fuel gases, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gases, quick connectors for cooling water and oil, and quick connectors for semiconductors.

[0003] In an autoclave or pressure vessel, a quick connector can achieve a quick connection, and can compensate for changes in temperature and pressure in the autoclave or pressure vessel, maintain good sealing performance and transport the medium. However, existing quick connectors all use rubber seals, so that they can only be used at lower temperatures, resulting in the inability to effectively meet the high temperature and high pressure use environment.

[0033] Example:

[0034] The present application embodiment discloses a high temperature resistant quick connector. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a ball joint 1, a conical joint 5 is arranged on the outside of one side of the ball joint 1, the end of the ball joint 1 away from the conical joint 5 is connected to a bracket nozzle 2, and the end of the conical joint 5 away from the ball joint 1 is connected to a bracket nozzle 2 6, the ball joint 1 and the conical joint 5 are symmetrically provided with a ball plug 3 and a small spring 4 inside, and the small spring 4 on each side is arranged on the outer side wall of the ball plug 3, the ball joint 1, the bracket nozzle 2, the ball plug 3, and the small spring 4 together constitute an integrated ball-conical metal sealing structure, and the ball plug 3, the small spring The spring 4, the conical joint 5, and the bracket nozzle 2 6 together constitute an integrated ball-conical metal sealing structure 2, the outer wall of the conical joint 5 is provided with a pressing sleeve 11, and a large spring 12 is provided inside one side of the pressing sleeve 11, and the large spring 12 is located on the outer wall of the conical joint 5, and the ball joint 1 and the connection of the outer side of the pressing sleeve 11 are jointly provided with a movable lever assembly, and the movable lever assembly, the integrated ball-conical metal sealing structure 1, the integrated ball-conical metal sealing structure 2, the pressing sleeve 11, and the large spring 12 together constitute a split ball-conical metal sealing structure;

[0035] The bracket nozzle 2 includes a guiding structural member 1, a plugging structural member 1, and a nozzle structural member 1, and the guiding structural member 1, the plugging structural member 1, and the nozzle structural member 1 are arranged in sequence. The bracket nozzle 6 includes a guiding structural member 2, a plugging structural member 2, and a nozzle structural member 2, and the guiding structural member 2, the plugging structural member 2, and the nozzle structural member 2 are arranged in sequence.

[0036] Please refer to Figure 1 , Figure 6 and Figure 7 , the movable lever assembly includes a long rotating shaft 7, a short rotating shaft 8, a rotating rod 9, and a lever 10, and the movable lever assembly is symmetrically distributed on the outer side between the spherical joint 1 and the compression sleeve 11;

[0037] Two long rotating shafts 7 are linearly distributed on one side of the lever 10, and one side of the lever 10 is slidably clamped with the side end of the spherical joint 1 through one of the long rotating shafts 7, and the other side of the lever 10 is movably connected with a rotating rod 9 through the other long rotating shaft 7. The end of the rotating rod 9 far from the lever 10 is connected with a short rotating shaft 8, and one end of the rotating rod 9 is movably connected with the side end of the compression sleeve 11 through the short rotating shaft 8;

[0038] Among them, the movable lever assembly has a self-locking function under the cooperation of the compression sleeve 11 and the large spring 12. When it is connecting the spherical joint 1 and the tapered joint 5 as a whole, the change process of the large spring 12 is to increase pressure and compress itself, and after reaching the maximum compression value, it decompresses and compresses. The self-locking interval of the product is in the decompression compression interval of the large spring 12. After connecting the product, the movable lever assembly cannot open itself without external force in cooperation with the compression sleeve 11 and the large spring 12, and the product can work stably;

[0039] Moreover, the spherical surface of the spherical joint 1 and the conical surface of the tapered joint 5 are subjected to the elastic force of the large spring 12, so that the spherical surface and the conical surface form a mutual reaction force, causing elastic deformation and plastic deformation of the contact surfaces of the two. This cooperation of elasticity and plasticity enables the sealing surface after the product is connected to have good sealing performance, the ability to compensate for the relaxation of the sealing surface caused by temperature and pressure fluctuations, and ensures the stable operation of the high-temperature quick connector. At the same time, opening the spherical plug 3 installed inside allows the medium to pass through inside the quick connector.

[0040] Please refer to Figure 8 , when there is no spherical plug 3 and small spring 4, it can also form another implementation state of this quick connector. And to meet the use requirements, in some cases, the tapered and spherical spherical plug 3 will be changed to a tapered plug, and the corresponding contact surface will be changed to a spherical shape.

[0041] An integrated spherical-tapered metal self-sealing structure assembly one composed of a spherical joint 1, a spherical plug 3 located inside the spherical joint, a spring 4, and a support nozzle one 2 connected to the spherical joint. An integrated spherical-tapered metal self-sealing structure assembly two is composed of the spherical plug 3, the spring 4, a tapered joint 5, and a support nozzle two 6 on the right side of the integrated spherical-tapered metal self-sealing structure assembly one; the support nozzle one 2 is connected to the spherical joint 1, and the small spring 4 generates elastic force, causing the spherical surface of the spherical plug 3 to be pressured and the inner conical surface of the spherical joint 1 to be pressured. Under the action of the spring, this spherical surface and conical surface form mutual reaction forces, causing elastic deformation and plastic deformation of the contact surfaces of the two. This cooperation of elasticity and plasticity enables the sealing surface after the product is connected to have good sealing performance, the ability to compensate for the relaxation of the sealing surface caused by temperature and pressure fluctuations, ensuring the stable operation of the high-temperature quick connector. The movable lever assembly connects the integrated spherical-tapered metal self-sealing structure assembly one and the integrated spherical-tapered metal self-sealing structure assembly two, forming a split-type spherical-tapered metal self-sealing structure.

[0042] The implementation principle of this embodiment is as follows: When the quick connector is connected and in a high-temperature and high-pressure pressure vessel, the quick connector can operate stably. For the two normally closed connectors (the spherical joint 1 and the tapered joint 5), after the product is connected, the joint channel is opened, and it can be inflated or evacuated without leakage to maintain normal operation. And the overall quick connector adopts a full-metal sealing structure, and the metal sealing surface can be plated with substances such as silver to mainly increase the sealing performance while ensuring good sealing performance during operation, compensating for the sealing relaxation problem caused by temperature and pressure fluctuations, and operating stably in high and low pressure and high and low temperature environments.

[0043] In some cases, an internal plug is not required. At this time, the split-type spherical-tapered metal sealing structure is as shown in the figure, and it can be connected in various forms such as threaded connection and lever connection. The spherical surface of the spherical joint and the conical surface of the tapered joint are pressured by the elastic force of the large spring to generate a sealing surface.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
