Proportional pressure-reducing valve used for beer freshness preservation bucket

Abstract

The invention discloses a proportional pressure-reducing valve used for a beer freshness preservation bucket. The proportional pressure-reducing valve comprises a pressure-reducing valve seat, a pressure-reducing valve element and a pressure-reducing valve cover which are arranged in sequence from the high-pressure end in the front of the valve and the low-pressure end at the back of the valve, a medium flow inlet is formed in the pressure-reducing valve seat, a medium flow outlet is formed in the pressure-reducing valve cover, and a one-way valve containing a one-way valve body is arranged at the medium flow outlet. The proportional pressure-reducing valve is provided with the one-way valve, and the one-way valve contains a force action position, so that the valve can be opened by triggering the force action position; the proportional pressure-reducing valve is installed on a gas storage tank of the draft beer freshness preservation bucket, the gas storage tank is maintained to be sealed after gas is introduced into the tank, and after the gas is introduced into the gas storage tank, the one-way valve can be opened by triggering the force action position so that the gas can flow out of the storage tank.

Description

technical field [0001] The invention relates to the technical field of production of beer fresh-keeping barrels, in particular, the invention relates to a proportional pressure reducing valve for beer fresh-keeping barrels. Background technique [0002] Draft beer is famous all over the world for its "pure flavor, fresh and delicious", and it is a wonderful flower in beer. But because draft beer must adopt complicated special-purpose equipment to sell and store, thereby has limited its popularization, can not enter thousands of households. Although the barreled beer also uses fresh beer (pure draft beer without sterilization), but because there is not enough pressure in the barrel to maintain the carbon dioxide content in the wine, it will be oxidized in contact with air during the process of loading, transporting, and selling wine, thus destroying it. The taste and flavor of the wine. [0003] With the development of draft beer container technology, although Heineken’s Ir...

AI Technical Summary

Problems solved by technology

However, because draft beer must be sold and stored with complex special equipment, its popularization is limited, and it cannot enter thousands of households.

Although the barreled beer also uses fresh beer (pure draft beer without sterilization), but because there is not enough pressure in the barrel to maintain the carbon dioxide content in the wine, it will be oxidized in contact with air during the process of loading, transporting, and selling wine, thus destroying it. Wine Taste and Flavor

[0003] With the development of draft beer container technology, although Heineken’s Iron King Kong 5L has made up for the above defects and can maintain the quality of fresh barrel beer to the last drop, but because the barrel cannot be reused, it is expensive and unfriendly to the environment. The carbon dioxide compression system (fixed with glue) attached to the wine barrel is mixed with the wine, making consumers doubt its hygiene
