Description

Technical Field

[0001] The utility model relates to the technical field of liquor equipment, in particular to a spear for liquor with a pressure relief structure. Background Art

[0002] With the improvement of the quality of life, people have higher requirements for drinking. Canned and bottled beers can hardly meet people's drinking needs. More and more people hope to drink fresh, hygienic, delicious and pure beer. A keg is a tool for holding liquor. Generally, a spear is arranged at the mouth of the keg, and the spear cooperates with a dispenser to press out the liquor in the keg.

[0003] The liquor stored in the keg, especially liquor beverages such as fresh beer, will continuously ferment inside, resulting in a relatively large internal pressure in the keg. Therefore, when using the dispenser to press out the liquid in the keg, it is easy to have a large impact on the liquor outlet due to the too high internal pressure in the keg. In severe cases, phenomena such as spraying and barrel explosion will occur, which poses certain potential safety hazards. Summary of the Utility Model

[0027] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations. Embodiment 1

[0028] Combined with Figures 1 to 9 As shown, the present utility model discloses a wine lance with a pressure relief structure, which includes a cover body and a wine outlet valve group 200 cooperatively installed with the cover body, and further includes a pressure relief valve group 100. The pressure relief valve group 100 is arranged in the middle of the wine outlet valve group 200. The pressure relief valve group 100 is integrally arranged in the wine outlet valve group 200, and preferably adopts a central position arrangement design. Combined with the cooperation between the wine lance and the wine barrel, it is convenient to adjust the pressure in the wine barrel and avoid the problem of too high internal pressure.

[0029] In a specific structure, the pressure relief valve group 100 includes a pressure relief valve body and a pressure relief valve rod 130. A pressure relief cavity 101 is provided inside the pressure relief valve body. A pressure relief hole 102 is provided at the top of the pressure relief cavity 101. The pressure relief valve rod 130 is internally configured to be fitted and installed in the pressure relief cavity 101. The upper end of the pressure relief valve rod 130 can penetrate through the pressure relief hole 102. A first spring 160 is sleeved on the pressure relief valve rod 130. A valve core 140 is provided at the lower part of the pressure relief valve rod 130. A valve core is fitted in a ball valve groove 131. The ball valve groove 131 is located at the bottom of the pressure relief valve rod 130. The lower part of the valve core 140 is used to block a pressure relief flow channel 151. Among them, the lower part of the pressure relief hole 102 is an flared hole structure. When the internal pressure exceeds the elastic bearing capacity of the first spring 160, the valve core 140 arches upward. A gap appears between the valve core 140 and the pressure relief flow channel 151. The valve core 140 no longer blocks the pressure relief flow channel 151. The internal air pressure exhausts outward through the gap between the valve core 140 and the pressure relief flow channel 151. At this time, usually the pressure relief valve rod 130 moves upward along with the upward movement of the valve core 140, so that a gap is also formed between the pressure relief valve rod 130 and the pressure relief hole 102. In other embodiments, a pressure relief gap itself exists between the pressure relief valve rod 130 and the pressure relief hole 102, thus realizing the pressure relief function.

[0030] Combined with the above, the pressure relief valve body includes a pressure relief valve cover 110, a pressure relief valve seat 120, and a pressure relief flow channel seat 150. A sealing ring is provided between the pressure relief valve cover 110 and the pressure relief valve seat 120 to achieve assembly sealing. The pressure relief hole 102 is located on the pressure relief valve cover 110, usually at the central position. The pressure relief valve seat 120 is fitted and installed with the lower part of the pressure relief valve cover 110. The pressure relief flow channel seat 150 is installed in the bottom inner cavity of the pressure relief valve seat 120. The pressure relief flow channel 151 is located inside the pressure relief flow channel seat 150. Among them, the pressure relief flow channel 151 in the pressure relief flow channel seat 150 is used to communicate with the inner cavity of the barrel body for fitting and installing the wine spear.

[0031] Combined with the above, the pressure relief flow channel 151 includes a pressure relief flow channel body and a pressure relief port 152 located at the upper part of the pressure relief flow channel body. The pressure relief port 152 is used to cooperate with the valve core 140. The valve core 140 adopts a valve ball. The pressure relief port 152 is in a bowl-shaped structure to match the spherical surface of the valve ball. Optimizing the design of the pressure relief port structure is convenient for cooperating with the spherical valve core, increasing the sealing stability, and also increasing the pressure relief stability.

[0032] The utility model uses a pressure relief valve group provided at the center of the wine spear, which can ensure the balance of the pressure in the barrel, avoid the high-pressure state inside the wine barrel, and improve the smoothness and safety of wine pouring. Integrating the pressure relief valve group into the wine spear as a whole makes the overall structure more compact and reasonable. Embodiment 2
