[0032] The inner wall of the inner ring 4 is connected with a hollow pressure relief valve body 9, the top of the pressure relief valve body 9 is provided with a first truncated cone 10 extending outward, and the top of the inner wall of the wine spear cover 1 is provided with a second truncated cone 11 extending inward, and the first truncated cone 10 and the second truncated cone 11 are at the same height;

[0033] A soft rubber 24 adapted to and mounted on the pressure relief valve body 9 is provided below the first truncated cone 10 and the second truncated cone 11. In the present embodiment, the soft rubber 24 is provided in a convex shape. A hard rubber 28 is provided below the soft rubber 24. The hard rubber 28 is also mounted on the pressure relief valve body 9 and is integrally formed with the soft rubber 24.

[0034] In this embodiment, the hard rubber is configured as a T-shaped ring, and a sealing groove is opened on the outer circumferential surface of the pressure relief valve body 9. A pressure relief valve body silicone ring 12 is installed in the sealing groove. The lower part of the hard rubber tightly covers the pressure relief valve body silicone ring 12, thereby completing the sealing between the pressure relief valve body 9 and the hard rubber.

[0035] A vertically arranged soft and hard rubber spring 13 is connected between the multiple cross ribs 7 and the hard rubber. The soft and hard rubber spring 13 is in a compressed state. The soft and hard rubber spring 13 presses the hard rubber 28 and the soft rubber 24 against the inner top wall between the pressure relief valve body 9 and the wine spear cover 1 through its elastic potential energy.

[0036] A limiting ring 14 is provided on the upper side of the inner side wall of the pressure relief valve body 9, a pressure relief valve base 15 is screwed to the inner side wall of the lower part of the pressure relief valve body 9, a pressure relief valve base silicone ring 16 for sealing is installed at the thread root of the two, and a pressure relief valve core 17 is slidably connected inside the pressure relief valve body 9;

[0037] In this embodiment, the pressure relief valve core 17 is located below the limiting ring 14, and the top of the pressure relief valve core 17 is set to be soft rubber, and the non-soft rubber part of the pressure relief valve core 17 is provided with a plurality of first vertical ribs 18 symmetrically distributed about the center of the pressure relief valve core 17, and the outer surfaces of the plurality of first vertical ribs 18 abut against the inner side wall of the pressure relief valve body 9;

[0038] A circular groove hole 19 is opened on the lower surface of the pressure relief valve core 17, and a valve core spring 20 is arranged between the pressure relief valve base 15 and the inner top wall of the circular groove hole 19. In this embodiment, the valve core spring 20 is in a compressed state. The valve core spring 20 uses its elastic potential energy to press the top soft rubber of the pressure relief valve core 17 against the lower surface of the limit ring 14, thereby sealing the inside of the pressure relief valve body 9.

[0039] Furthermore, the pressure relief valve base 15 includes an upper ring body 21 and a lower ring body 22 connected to each other, wherein the outer wall of the upper ring body 21 is provided with a thread for installing the pressure relief valve base 15 as a whole, and a plurality of second vertical ribs 23 evenly distributed with the center of a circle are provided on the inner wall of the upper ring body 21; vertically arranged small cylinders 25 are installed between the plurality of second vertical ribs 23; the above-mentioned valve core spring 20 is located on the plurality of second vertical ribs 23 and is arranged around the small cylinders 25; the lower ring body 22 of the pressure relief valve base 15 has an upward opening 26 and is connected with a plurality of fan-shaped areas formed by the plurality of second vertical ribs 23, and a long wine outlet tube 27 is installed on the inner wall of the lower ring body 22, thereby forming a wine outlet pressure relief passage.

[0040] The working principle and beneficial effects of the present invention are:

[0041] First, the whole structure is installed on the corresponding wine barrel through the wine spear cover 1. When the operation of pressurizing and filling wine is performed: use the dispenser to press the positions of the soft glue 24 and the hard glue 28. The soft glue 24 is pressed down and no longer squeezes and contacts the wine spear cover 1. At the same time, the soft and hard glue springs 13 are compressed by pressure, thereby opening the wine inlet channel. Gas or wine enters the structure from the channel between the soft glue 24 and the wine spear cover 1. Gas or wine enters the barrel body through the elliptical hole 8 on the soft and hard glue spring base 2. After the pressure charging or wine filling is completed, just lift the dispenser. The resilience of the soft and hard glue springs 13 will push the hard glue 28 and the soft glue 24 upwards, completing the seal with the wine spear cover 1 again.

[0042] During the pressure relief and wine discharging operation: after the pressure is charged, the barrel is in a pressure-maintaining state. To discharge the wine, you only need to press the pressure relief valve core 17 with a suitable wine discharging device. The soft rubber part of the pressure relief valve core 17 is squeezed and no longer contacts the limiting ring 14 of the pressure relief valve body 9, thereby opening the pressure relief passage for discharging the wine. The gas enters the long wine discharging tube 27 and enters the pressure relief passage for discharging the wine through the opening 26 of the lower ring body 22 of the pressure relief valve base 15. Finally, the gas or wine completes the wine discharge or pressure relief from the gap between the pressure relief valve core 17 and the limiting ring 14 of the pressure relief valve body 9.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
