Technical Field
[0001] This utility model relates to the technical field of wine spear devices, specifically a wine spear with a pressure relief valve. Background Technology
[0002] The beer spout is the dispensing valve for draft beer kegs. It is used to dispense beer from draft beer kegs, and it is connected to the keg neck thread for sealing. It works with the same type of filling line and dispenser to achieve the purpose of filling and dispensing beer through the exchange of CO2 and draft beer. The beer cap is the sealing cap of the keg. In order to ensure that the pressure inside the keg can be released in time, the beer cap is usually equipped with a pressure relief valve.
[0003] Currently, the pressure relief device formed by the existing movable plug, fixed plug, and pressure relief spring is coaxial with the wine base, which allows the height of the wine base to be further reduced, the structure to be simpler, and the cost to be further reduced; at the same time, the pressure relief spring is a tension spring, so the spring's return function will not be affected by syrup adhering to the spring.
[0004] For example, a wine spear with manual and automatic pressure relief valves disclosed in authorized public account CN209506519U includes a wine spear base. An inner tube fixing sleeve is installed at the bottom opening of the wine spear base. A top block return spring is fitted outside the inner tube fixing sleeve. The two ends of the top block return spring abut against the inner tube fixing sleeve and the raised top block, respectively. The top block return spring holds the raised top block in place, making it fit against the inner wall of the wine spear base. An inner tube coaxial with the wine spear base is provided inside. The top flange of the inner tube engages with the raised top block. The bottom of the inner tube passes through the raised top block and extends out from the inner tube fixing sleeve. The upper part of the wine spear base... A movable plug is installed at the top opening of the corresponding inner tube, and a fixed plug is fixed at the bottom opening of the inner tube. The fixed plug has a hollow structure. The movable plug and the fixed plug are connected by a pressure relief spring, which is a tension spring. The two ends of the pressure relief spring hook the movable plug and the fixed plug respectively. The upper surface of the movable plug has an "I"-shaped or "+"-shaped opening groove. The movable plug and the wine jug have concave and convex mating surfaces. A sealing ring is installed inside the wine jug for sealing when the wine jug and the wine barrel are in contact. The top of the wine jug also has a cavity for connecting to an external wine dispensing valve. However, with such a wine jug with manual and automatic pressure relief valves, dust and impurities can enter the wine jug through the pressure relief valve opening and contaminate the wine. Furthermore, the wine jug is inconvenient to remove after being tightened.
