[0006] Preferably, the diameter of the sliding cavity is larger than the diameter of the tube hole, and the diameter of the exhaust cavity is larger than the diameter of the tube hole.
[0007] In order to achieve a better exhaust effect, the communication channel is arranged in an L shape.
[0008] In order to achieve the purpose of bottom pressure more quickly, the aperture of the pressure hole is smaller than the aperture of the sliding cavity.
[0009] Furthermore, the sealing gasket is vertically arranged above the communicating channel.
[0010] In order to achieve a sealing effect, the sliding plug is made of silicone material.
[0011] The beneficial effects achieved by the utility model using the above structure are as follows: a pressure vessel tank pipe mouth sealing device proposed in this scheme punches the sliding plug through the high pressure in the pressure hole. At this time, the sliding plug is squeezed to the upper limit of the sealing gasket and fixed. At this time, the sealing gasket will block the inlet and outlet of the connecting channel to avoid gas leakage, thereby achieving good sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0018] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model proposes a pressure vessel storage tank pipe mouth sealing device, including a pressure vessel storage tank 1 and a sealing structure 2, the sealing structure 2 is arranged above the pressure vessel storage tank 1, the sealing structure 2 includes a sealing tube 3, a sealing plug 4, a sliding cavity 5, a pipe hole 6, an exhaust cavity 7, an exhaust pipe 8, a hydraulic column 9, a sliding plug 10, an air inlet 11, a pressure hole 12, a communicating channel 13 and a sealing gasket 14, the sealing tube 3 is fixedly arranged above the pressure vessel storage tank 1, the sealing plug 4 is threadedly sealed on the sealing tube 3, the sliding cavity 5 is penetrated at the bottom of the sealing plug 4, the pipe hole 6 is penetrated in the middle position of the sealing plug 4 and is connected to the sliding cavity 5, the diameter of the sliding cavity 5 is larger than the diameter of the pipe hole 6, and the exhaust cavity 7 is arranged The sealing plug 4 is located in the middle and connected to the pipe hole 6. The diameter of the exhaust chamber 7 is larger than the diameter of the pipe hole 6. The exhaust pipe 8 is connected to the side of the sliding chamber 5. The hydraulic column 9 passes through the exhaust chamber 7 and is fixed on the top of the sealing plug 4. The sliding plug 10 is slidably arranged in the sliding chamber 5 and fixed at the bottom of the hydraulic column 9. The sliding plug 10 is made of silicone material. The air inlet hole 11 passes through the lower side wall of the sealing plug 4 and is connected to the sliding chamber 5. The pressure hole 12 passes through the bottom of the sealing plug 4. The aperture of the pressure hole 12 is smaller than the aperture of the sliding chamber 5. The communicating channel 13 passes through the sliding plug 10. The communicating channel 13 is L-shaped. The sealing gasket 14 is fixed above the sliding chamber 5. The sealing gasket 14 is vertically arranged above the communicating channel 13.
[0019] When using the device in a specific way, the user first pushes the hydraulic column 9 to slide the sliding plug 10 downward. At this time, the connecting hole 13 on the sliding plug 10 is connected to the air inlet 11. At this time, the pressure vessel storage tank 1 is inflated through the exhaust pipe 8. At this time, the gas flows into the sliding cavity 5 through the exhaust chamber 7 and the pipe hole 6, and then flows into the pressure vessel storage tank 1 through the connecting hole 13 and the air inlet 11. After the filling is completed, the hydraulic column 9 is controlled to rise. At this time, the sliding plug 10 slides upward in the sliding cavity 5 until the sliding plug 10 slides to the top of the sliding cavity 5 and squeezes onto the sealing gasket 14.
