[0022] Specifically, the sealing cap 2 is an inverted cone frustum, with a diameter gradually decreasing from top to bottom, used to position the liquid adding pipe head 1 on the liquid adding port of the tank car tank, and to seal the liquid adding port during liquid addition, avoiding the volatile gas of the solution from overflowing outward during the liquid addition process.

[0023] During use, the first probe 32 and the second probe 33 are inserted into the tank car along with the liquid adding pipe head 1, and as the liquid level in the tank car rises, both the first probe 32 and the second probe 33 come into contact with the solution in the tank, forming a loop with the control mechanism 31, the first probe 32 and the second probe 33, and the operation mechanism of the trigger device 3 is triggered, stopping the liquid adding pump of the crane pipe that is running.

[0024] Please refer to Figure 1In one embodiment, the height of the first probe 32 is less than the height of the second probe 33; the first connecting line 34 and the second connecting line 35 pass through the sealing cap 2 and are connected with the control mechanism 31. Specifically, in this embodiment, the height of the second probe 33 corresponds to the triggered liquid level. By making the first connecting line 34 and the second connecting line 35 pass through the sealing cap 2, the first connecting line 34 and the second connecting line 35 can be prevented from being clamped between the sealing cap 2 and the liquid inlet of the tank when liquid is added, which can affect the sealing effect and cause damage to the outer skin of the first connecting line 34 and the second connecting line 35.

[0025] Please refer to Figure 1 In one embodiment, the anti-overflow swan neck head further comprises an adjustable straight pipe 36; the top of the adjustable straight pipe 36 is inserted into the sealing cap 2 from below and is movably connected with the sealing cap 2; the second probe 33 is fixedly connected with the bottom of the adjustable straight pipe 36; and the second connecting line 35 passes through the adjustable straight pipe 36 and the sealing cap 2 in sequence and is connected with the control mechanism 31. Specifically, the adjustable straight pipe 36 can be adjusted in the vertical direction, so as to change the position of the bottom. The second probe 33 is fixed at the bottom of the adjustable straight pipe 36, and when the adjustable straight pipe 36 moves upward, the position of the second probe 33 also moves upward. By providing the adjustable straight pipe 36, the position of the second probe 33 can be adjusted, so that the height of the triggered liquid level can be adjusted as needed.

[0026] Please refer to Figure 2 In one embodiment, a fixing structure 4 is arranged below the sealing cap 2; the fixing structure 4 is fixedly connected with the outer side wall of the liquid filling pipe head 1; the adjustable straight pipe 36 passes through the fixing structure 4; and the fixing structure 4 is detachably connected with the adjustable straight pipe.

When filling liquid such as nitric acid solution which can produce volatile gas, after the completion of loading, there is often still a lot of nitric acid solution remaining in the liquid filling pipe head 1, which will continue to emit acidic gas, which is harmful to workers who are long-term activities nearby. By setting the suction port 11, the volatile harmful gas remaining in the liquid filling pipe head 1 after the liquid filling is completed can be sucked to avoid its overflow.

[0030] Please refer to Figure 1 In one embodiment, a plurality of suction ports 11 are arranged circumferentially along the pipe wall of the liquid filling pipe head 1, and by sucking at multiple positions, the effect of suction can be better.
