[0040] In the connecting device of this embodiment, a sealing ring 222 is embedded in the head cap 22 , and the sealing ring 222 is arranged around the rotating component 23 .

[0041] In the connecting device of this embodiment, the movable joint 1 includes a movable groove 12, and the connecting port 11 is arranged at the bottom of the movable groove 12; the connecting device also includes a clamping ring 3, which is connected to the inner wall of the movable groove 12, and a sealing component 4 is arranged between the clamping ring 3 and the bottom of the movable groove 12, and the sealing component 4 is used to seal the mounting structure 2 and the component to be connected 20.

[0045] Embodiment 1:

[0046] ① Pre-installation operation of the valve core:

[0047] Place the valve core base horizontally, place the valve core (equivalent to the component 10 to be installed) inside the central groove of the valve core base, with the valve core facing vertically upwards, and place the device vertically from top to bottom, with the movable joint 1 of the device coaxially aligned with the valve core base, turn the rotating part 23 counterclockwise, and at the same time, the rotating part 23 will be lifted upwards until the rotating part 23 cannot rotate, lift the device upwards, separate the device from the valve core base, and complete the valve core pre-installation.

[0048] ②Operation of installing the valve core:

[0049] Align the device and the valve core joint coaxially, hold the device head cap 22 with one hand, and turn the device movable joint 1 clockwise with the other hand. The central internal thread of the movable joint 1 is screwed into the external thread of the valve core joint and tightened. Hold the device head cap 22 with one hand, and turn the rotating part 23 clockwise with the other hand. At the same time, the rotating part 23 will be fed downward as a whole until the rotating part 23 cannot be turned. Loosen the movable joint 1 counterclockwise to disengage the device from the valve core joint.

[0050] Embodiment 2:

[0051] The movable joint 1 is connected and fixed with the clamp ring 3 by three bolts. There is a rotation gap between the inner diameter of the clamp ring 3 and the outer diameter of the airway joint. Therefore, the movable joint 1 has axial rotation freedom. During the tightening process of the device, the airway joint 21 and the above parts can be kept from rotating with the tightening of the movable joint 1, which is convenient for operation. At the same time, the bowl-shaped sealing ring (equivalent to the sealing component 4) is elastically deformed due to the extrusion of the end faces at both ends, and the two ends of the sealing ring are tightly attached to achieve the effect of sealing the device and the joint valve core joint.

[0052] The center of the airway connector 21 is provided with an internal thread, which fits the external thread of the valve core. During the medium filling process of the device and the system, the airway connector 21 uses the internal thread to stably clamp the valve core of the valve to prevent the valve core from falling into the fluorine injection nozzle and affecting the filling rate.

[0053] A half-moon-shaped through hole is provided in the middle ring of the airway connector 21. During the medium filling process of the device and the system, the through hole plays a drainage role, leaving only a small part to flow through the gap between the rotating component 23 and the center hole of the airway connector 21. It is prevented that the medium flow rate in the center hole of the airway connector 21 is too high, which affects the clamping of the valve core of the device.

[0054] The head of the rotating component 23 is provided with an "I" groove, which fits the head of the valve core, so that during the process of pre-installing the valve core and installing the valve core, the rotating component 23 can quickly bite the valve core to complete the operation of disassembling and installing the valve core of the device.
