Description

A wine and beverage fresh-keeping barrel with adjustable head

technical field

The utility model belongs to the technical field of beer fresh-keeping barrels, in particular to a wine and beverage fresh-keeping barrel with adjustable head.

Background technique

Draft beer is beer that has been filtered through a microporous membrane, while ordinary beer is beer that has been sterilized by high temperature. It is not only different from high-temperature sterilized bottled and canned cooked beer, but also different from unsterilized bulk beer, but a pure natural, colorless, preservative-free, sugar-free, and high-quality wine without any flavor. Very nutritious. Draft beer is a wonderful flower in the beer kingdom, and the proportion of beer consumption in the world is getting higher and higher. The draft beer, known as "beer original juice", is made by injecting the highest quality sake directly from the production line into a fully enclosed stainless steel barrel. When drinking, the draft beer machine is used to charge carbon dioxide, and the draft beer machine is used to control the wine at 3 ~ 8 ℃, drink it. When the beer is directly hit from the beer machine into the beer mug, the contact between the beer and the air is avoided, so that the beer is fresher, thicker, and the foam is richer. The yeast contained in draft beer can promote gastric secretion, increase appetite and strengthen digestion. However, since draft beer must be sold and stored with complex special equipment, its popularity is limited and cannot enter thousands of households.

With the development of draft beer container technology, the commonly used draft beer container adopts the method of separate setting of the gas supply device (providing carbon dioxide) and the beer barrel, which is very inconvenient to carry. The quality of the fresh barrel beer is maintained to the last drop, but because the barrel cannot be reused, the price is high and it is not environmentally friendly. At the same time, the carbon dioxide compression system (fixed with glue) attached to the barrel is mixed with the wine liquid, allowing consumers to Hygiene raises doubts. Therefore, designing a product to solve the above-mentioned deficiencies of beer packaging and to provide consumers with high-quality fresh beer at low cost has become an urgent problem to be solved. However, when the general draft beer container is out of wine, its liquid flow is fixed, and the flow of wine cannot be controlled, which makes it very inconvenient for people to use.

Among them, the wine spear is the wine outlet valve of the draft beer barrel, which is an indispensable part in the draft beer container. Its function is to achieve the purpose of filling and discharging through the exchange of CO2 and draft beer. However, the commonly used wine spears all require a pressure reducing valve and a trachea to connect the carbon dioxide gas storage chamber, which makes disassembly and assembly very inconvenient; in addition, the trachea is easy to be knocked and damaged, resulting in air leakage, resulting in frequent replacement of tracheal components and frequent replacement of trachea. Damage can also easily lead to air leakage and deterioration of draft beer.

In addition, the gas inside the air supply device of the ordinary draft beer container is constant. When the internal gas is used up, people cannot inflate it, so it cannot be reused; and when the internal air pressure is not enough, if there is remaining draft beer, it will lead to The remaining draft beer can no longer come out, resulting in waste. Therefore, it is essential to equip the draft beer container with an inflation valve. Among them, the inflation valve is a one-way valve that can be inflated in one direction. The common inflation valve is often closed in reverse through an elastic device. When the elastic device fails, the one-way flow function will not exist.

(3) Beneficial effects

Compared with the prior art, the wine head of the dispenser of the present invention has a structure with a throttle valve, so that the product can adjust the liquid flow rate of the wine through the dispenser; The air pipe and the decompression device between the wine spear in series and the air storage chamber are omitted, so that the structural assembly of the wine and beverage fresh-keeping barrel is more simple and clear, economical and practical.

Among them, a throttle valve is set inside the wine head of the dispenser, which can be used to control the on-off between the liquid outlet and the liquid inlet in the wine head, so as to achieve the purpose of controlling the liquid flow inside the wine head, and then The dispenser has the effect of controlling the flow of wine, which is convenient for people to adjust the flow of wine according to actual needs; and the valve switch of the throttle valve adopts a knob switch structure to realize opening and closing, which is simple in structure and convenient in operation; The setting of the body limiter prevents the valve body from being completely pulled up together with the valve switch, thereby effectively preventing the wine from coming out of the throttle valve installation hole.

Among them, the wine spear of the present utility model has its own pressure reducing valve, which can control the opening and closing of the valve device through the up and down movement of the wine head of the dispenser, and then control the opening and closing of the pressure reducing valve, so that the product can directly pass through the gas storage without a trachea The cavity and the wine storage cavity save space and are easy to assemble; while the valve device composed of screws, top block return springs, top blocks and top rods only needs the wine head to overcome the spring force of the top block return spring during movement. The second ejector rod can be opened to guide carbon dioxide gas into the piston movable hole of the wine spear seat; and the pressure reducing valve can adjust the stable output pressure by adjusting the threaded structure of the knob, which is simple in structure and easy to operate; and, The sealing gasket arranged between the top surface of the inner tube fixing sleeve and the bottom surface of the large hole of the third counterbore can increase the sealing performance of the connection between the two and prevent the gas from directly entering the wine storage cavity from the gas storage cavity.

The inflatable valve of the utility model utilizes the reset force of the valve core return spring and the air pressure inside the air cavity of the draft beer fresh-keeping barrel, and the two work together to prevent the gas in the air cavity of the draft beer fresh-keeping barrel from leaking out of the inflatable valve, thereby improving the inflatable valve. When the reset force of the valve core return spring fails, as long as the air pressure in the air cavity of the draft beer fresh-keeping barrel is large enough, the air pressure can also act on the lower port of the valve core to seal the inflatable countersink to prevent the gas from being inflated. The valve leaks out, effectively improving the service life of the inflation valve.
