When high-pressure gas is present in the high-pressure container 50, the high-pressure gas further applies pressure to the movable valve element 21, thereby ensuring the tightness of the seal of the movable valve element 21. When the self-sealing device works, the pushing assembly 40 pushes the filling and discharging head 30 out, the filling and discharging sleeve 31 sleeves the self-sealing interface 20, the connection part of the filling and discharging sleeve 31 and the self-sealing interface 20 forms a seal, a space between the filling and discharging sleeve 31 and the self-sealing interface 20 forms an inflation space, and the high-pressure hose 34 is communicated with the inflation space. With the filling and discharging sleeve 31 covering the self-sealing interface 20, the thimble 32 abuts against the movable valve core 21, the elastic member 22 is compressed, the opening of the high-pressure container 50 is released, the opening of the high-pressure container 50 is communicated with the inflation space, the high-pressure hose 34 is also communicated with the inflation space, and the high-pressure container 50 can be filled with pressure or discharged with pressure through the high-pressure hose 34.

After the pressurization or the pressure relief is completed, the charging and discharging sleeve 31 is pulled away in the direction away from the self-sealing interface 20, the movable valve core 21 is gradually released by the ejector pin 32, the movable valve core 21 is reset under the action of the elastic force of the elastic piece 22, the charging and discharging sleeve 31 is not separated from the self-sealing interface 20, and the ejector pin 32 is not abutted to the movable valve core 21 any more, at the moment, the movable valve core 21 is completely reset, the high-pressure container 50 is sealed again, the space between the charging and discharging head 30 and the self-sealing interface 20 is sealed, residual gas in the space can be pumped away through the high-pressure hose 34, and the gas leakage loss is reduced.
Referring now to fig. 2, a self-sealing interface 20 of the present invention is shown. The self-sealing interface 20 further includes a valve seat 23, in order to realize the movement of the movable valve element 21 in the valve seat 23 and ensure that the movable valve element 21 is released, the inside of the high-pressure container 50 is communicated with the outside, an accommodating groove 231 for accommodating the movable valve element 21 and the elastic element 22 is arranged inside a first end of the valve seat 23, the first end is inserted into the opening of the high-pressure container 50 in a sealing manner, an air port 232 is formed at a second end of the valve seat 23, the size of the air port 232 is smaller than that of the accommodating groove 231, two ends of the elastic element 22 are respectively abutted to the bottom of the movable valve element 21 and the opening of the high-pressure container 50, and the top of the movable valve element 21 is abutted to the lower surface of the air port 232. In this embodiment, the elastic element 22 is a spring, the movable valve element 21 can move along the axial direction of the receiving groove 231, and in the non-operating state, the elastic element 22 presses the movable valve element 21 to make it closely contact with the lower surface of the air port 232, so that the movable valve element 21 seals the air port 232, thereby sealing the high-pressure container 50. Meanwhile, when high-pressure gas exists in the high-pressure container 50, the pressure direction generated by the high-pressure gas on the movable valve element 21 is consistent with the pressure direction of the spring elasticity on the movable valve element 21, so that the movable valve element 21 is more tightly pressed with the lower surface of the air port 232, and the self-sealing effect of the movable valve element 21 is ensured. In the first embodiment of the present invention, one valve seat 23 is provided, and correspondingly, one charging and discharging head 30 is provided, and the high-pressure hose 34 is connected to both the charging pipeline and the discharging pipeline, and both the charging pipeline and the discharging pipeline are provided with electromagnetic valves.

Therefore, the movable spool 21 can move only in the axial direction of the accommodation groove 231 without being displaced due to the restriction of the accommodation groove 231. At this time, there is no gap between the receiving groove 231 and the movable valve core 21, so that gas can flow through the self-sealing interface 20 after the movable valve core 21 is pressed down, an air passing space 24 is formed between the upper portion of the receiving groove 231 and the movable valve core 21, a hollow groove 211 is formed in the lower portion of the movable valve core 21, and the hollow groove 211 is communicated with the air passing space 24 through the air passing hole 212. Therefore, after the movable valve core 21 is pressed down, during punching, air enters the air passing space 24 between the movable valve core 21 and the accommodation space through the space between the thimble 32 and the air port 232, then flows into the hollow groove 211 from the air passing hole 212, and further enters the high-pressure container 50, and during pressure relief, the air reversely flows out. In this embodiment, the air holes 212 are disposed obliquely to conform to the flow direction of the air, so as to increase the speed of the air flowing in and out.
Furthermore, in order to improve the sealing effect of the movable valve core 21 on the air port 232, a sealing head 233 extends downwards from the lower edge of the air port 232, and a first sealing ring 25 is arranged at the position, corresponding to the sealing head 233, of the top of the movable valve core 21. Along with the movable valve core 21 abutting against the lower surface of the air port 232, the sealing head 233 is in complete contact with the first sealing ring 25, the first sealing ring 25 is extruded and deformed, and the sealing head 233 is coated, so that complete sealing is realized. In this embodiment, in order to ensure that the first sealing ring 25 is tightly connected with the movable valve element 21, a groove 213 is formed in the top of the movable valve element 21, the first sealing ring 25 is pressed in the groove 213 through the valve head 26, and the valve head 26 is locked with the top of the movable valve element 21. Therefore, even if the first seal ring 25 is pressed and deformed by the seal head 233, the first seal ring 25 is still sandwiched between the valve head 26 and the movable valve element 21 and does not separate from the movable valve element 21. Further, since the first sealing ring 25 is engaged with the sealing head 233, the valve head 26 locking the first sealing ring 25 is certainly inserted into the air port 232 when the movable valve core 21 presses the lower surface of the air port 232, and in order to enable the valve head 26 to be accurately inserted, the top of the valve head 26 is in a truncated cone shape capable of being inserted into the air port, so that the truncated cone side surface can form an insertion guide.
