Beer spear with pressure reducing valve

Abstract

The invention discloses a beer spear with a pressure reducing valve. The beer spear comprises a beer spear seat (1), the pressure reducing valve (2), an inner tube fixing sleeve (3), an inner tube fixing spring (4) and an inner pipe assembly (5), wherein the pressure reducing valve (2) is arranged on the outer side of the beer spear seat (1) in a matched mode, a pressure inlet of the pressure reducing valve (2) communicates with a gas storage cavity (6) in a matched mode, a beer head movable hole (11) matched with a beer head (71) of a distributor (7) is formed in the top end of the beer spearseat (1), a valve device (12) matched with the beer head (71) in a linkage manner is arranged on the side surface of the beer head movable hole (11), and the valve device (12) correspondingly communicates with a pressure stabilizing outlet of the pressure reducing valve (2) and the beer head movable hole (11). According to the beer spear with the pressure reducing valve, a beer storage cavity candirectly communicate with a gas storage cavity through the pressure reducing valve, so that an air pipe with the transition connection function is omitted, then the disassembly and the assembly of adraft beer keg are more convenient, the space of the draft beer barrel is saved, and the problems of air leakage, draft beer deterioration and the like caused by the damage of the air pipe are solved.

Description

Technical field [0001] The invention belongs to the technical field of beer preservation barrels, and particularly relates to a wine spear with a pressure reducing valve. Background technique [0002] Draft beer is beer that has been filtered through a microporous membrane, and ordinary beer is beer that has undergone high temperature sterilization. It is different from bottled and canned beer that has undergone high temperature sterilization, and it is also different from bulk beer that has not been sterilized. It is a pure natural, no coloring, no preservatives, no sugar, and no flavors. It is extremely nutritious. Draft beer is a wonderful flower in the beer kingdom, and its proportion in world beer consumption is increasing. Known as the "beer juice", the best quality sake is poured directly into a fully enclosed stainless steel barrel from the production line. When drinking, the draft beer machine is used to charge carbon dioxide, and the draft beer machine is used to cont...

AI Technical Summary

Problems solved by technology

Today’s commonly used wine spears all need a pressure reducing valve and a trachea to connect the carbon dioxide gas storage chamber, which makes disassembly and assembly very inconvenient; moreover, the trachea is easy to be bumped and damaged, resulting in air leakage, resulting in frequent replacement of trachea parts and the trachea. Damage can also easily lead to draft beer leakage and deterioration
