Description
Technical Field
The invention belongs to the technical field of beer fresh-keeping barrels, and particularly relates to a beer spear with a pressure reducing valve.
Background
Draught beer is beer filtered by microporous membrane, and common beer is beer sterilized by high temperature. It is different from bottled and canned cooked beer which is sterilized at high temperature and bulk beer which is not sterilized, but is a high-quality wine which is purely natural, has no pigment, no preservative, no sugar and no essence, and has very rich nutrition. Draught beer is a wonderful in the kingdom of beer and has an increasing proportion in world beer consumption. The draught beer known as "beer raw juice" is characterized by that the best quality clean wine is directly poured into a fully-closed stainless steel barrel from production line, when it is drunk, the draught beer machine is used for filling carbon dioxide, and the draught beer machine is used for controlling temp. 3-8 deg.C, and when it is drunk, the beer can be directly poured into the beer cup from the draught beer machine, so that it can prevent the beer from contacting with air, and can make the beer fresh, purer, rich in foam, tasty and refreshing, and its aftertaste is endless. Yeast contained in draught beer has effects of promoting gastric secretion, stimulating appetite, and promoting digestion. However, draught beer is limited in popularity because it must be sold and stored using complex special equipment, and cannot enter into thousands of households.
With the development of draught beer container technology, the commonly used draught beer container adopts a mode of separating an air supply device (for supplying carbon dioxide) from a beer barrel, and is inconvenient to carry; while the iron buddha beer 5L overcomes the defects, the quality of the fresh barrel beer can be kept to the last drop, but the barrel cannot be reused, so that the price is high, the environment is not protected, and meanwhile, a carbon dioxide compression system (fixed by glue) attached to the barrel is mixed with the wine, so that consumers are doubted about the sanitation of the beer. Therefore, designing a product to solve the above-mentioned drawbacks of beer packaging and to provide a high quality fresh beer to consumers at low cost is a highly desirable problem.
The beer spear is a beer outlet valve of the draught beer barrel, is an indispensable component in the draught beer container, and is used for achieving the purposes of filling and discharging beer through exchange of CO2 and draught beer. The common wine spear at present needs a relief valve and a gas pipe to connect the carbon dioxide gas storage cavity, so that the disassembly and the assembly are very inconvenient; moreover, the air pipe is easy to collide and damage, so that the air leakage condition occurs, the air pipe part is frequently replaced, and the air pipe is easy to damage, so that the draught beer is easy to leak air and deteriorate.
