[0002] In the oil transportation industry, as the main transportation tool, the safety and sealing performance of oil tank trucks are of crucial importance. The ball valve device of an oil tank truck is used to control the output and stop of liquid to ensure the safe transportation of liquid during transportation and loading and unloading. Although the traditional ball valve design of an oil tank truck can achieve basic liquid control, in the actual operation process, due to insufficient sealing performance, liquid leakage or valve failure may often occur, affecting transportation efficiency and safety. At the same time, under different transportation conditions, the liquid flow control of an oil tank truck needs to be precise to prevent potential safety hazards caused by excessive output or uneven output of liquid.

The adjusting turntable 14 is limited to rotate on the central valve pipe 13 for adjustment. The bottom connecting cover plate 21 is nested at the bottom of the threaded pipe 11, and the top connecting cover plate 22 is arranged on the top of the threaded pipe 11;

[0033] One end of the snap post 23 is fixedly connected to the bottom of the top connecting cover plate 22. The outer surface of the snap post 23 is nested on the bottom connecting cover plate 21. The soft pads 24 are nested at both ends of the bottom connecting cover plate 21 and the top connecting cover plate 22.

[0035] Embodiment 2

[0036] Such as Figures 1 - 4As shown in the figure, one-way mechanisms 3 are provided at both ends in the central valve pipe 13. The one-way mechanism 3 includes a one-way leak plate 31. An adjusting bearing 32 is provided on the outer surface of the one-way leak plate 31. A spring 33 is provided in the one-way leak plate 31. One end of the spring 33 is provided with a soft plug 34. A one-way pipe 35 is provided on the outer surface of one end of the soft plug 34. The inner surface of the adjusting bearing 32 is fixedly connected to the outer surface of the one-way leak plate 31. The outer surface of the adjusting bearing 32 is fixedly connected in the docking pipe 12. One end of the spring 33 is fixedly connected to the one-way leak plate 31. The end of the spring 33 away from the one-way leak plate 31 is fixedly connected to one end of the soft plug 34. The end of the soft plug 34 away from the spring 33 blocks the one-way pipe 35. The end of the one-way pipe 35 away from the soft plug 34 is nested in the central valve pipe 13.

[0037] In this embodiment, in order to further improve its practicality during actual use, a corresponding one-way mechanism 3 is provided in the central valve pipe 13. The staff can nest the end of the one-way pipe 35 away from the soft plug 34 in the central valve pipe 13, and then nest the outer surface of the adjusting bearing 32 in the docking pipe 12 and then transport the liquid. In this way, when the liquid is transported, it will flush out the soft plug 34 with the spring 33 through hydraulic pressure and transport it outward from one end of the one-way pipe 35. After transporting a certain amount, the hydraulic pressure will push back the soft plug 34 with the spring 33 to block the output. In this way, it can achieve semi-automatic output limitation during actual use, thereby further improving its practicality during actual use.

[0038] Working principle:

[0039] As Figures 1 - 4 shown in the figure, when the staff uses the ball valve sealing device to seal the oil tanker, whether it is during the process of storing oil or outputting oil, it can be operated by rotating the adjusting turntable 14. In the structure of the regulating valve, the threaded pipe 11 and the corresponding connecting mechanism 2 are used to make the transportation process more tight and stable. The staff can sleeved the pipeline to be transported on the outer surface of the threaded pipe 11 and make it fit tightly with the thread groove. Subsequently, the connecting mechanism 2 is used to firmly fix it. After the fixing is completed, the staff sleeved the bottom connecting cover plate 21 and the top connecting cover plate 22 on both ends of the threaded pipe 11 respectively, and firmly snapped the bottom snap post 23 of the top connecting cover plate 22 into the bottom connecting cover plate 21. In order to further enhance the sealing performance, a soft pad 24 can also be sleeved on one end of the bottom connecting cover plate 21 and the top connecting cover plate 22, and secondary fixing is carried out through the fixing plug 25 and the snap rack 26, so as to ensure a more sealed transportation effect during the transportation process.

[0040] To further enhance the practicality of the device, a one-way mechanism 3 is designed in the central valve tube 13. The staff can nest one end of the one-way tube 35 away from the soft plug 34 in the central valve tube 13 and nest the outer surface of the adjusting bearing 32 into the docking tube 12 to start liquid transportation. When transporting liquid, the hydraulic pressure will push the soft plug 34 with the spring 33, causing the liquid to be discharged from one end of the one-way tube 35. After transporting a certain amount, the hydraulic pressure will push the soft plug 34 with the spring 33 back, thus closing the output channel. This design enables the semi-automatic control of liquid transportation, ensures the accuracy of the output volume, and enhances the stability and sealing performance in actual use, significantly improving the practicality of the device.

[0041] This structure not only effectively prevents liquid leakage but also enables precise semi-automatic control according to needs during the storage and transportation of oil products, avoiding overfilling or underfilling situations and improving the reliability and operational simplicity of the tanker sealing system.
