Description

Structural improvement of beer picker adapter

The invention relates to a structural improvement of a beer picker adapter, in particular to a structural improvement of a beer picker adapter which is convenient for cleaning, assembly and structural stability.

Beer is a kind of wine that is quite popular in the world. Because it has low alcohol concentration, relatively affordable price and rich taste of bubbles, it is popular among consumers. However, it is different from other alcohols with higher alcohol concentration. Because beer has a low alcohol concentration, it does not produce the ability to sterilize and resist microbial contamination. Therefore, the cleaning cost and conditions of beer stored in traditional wooden barrels (for example, oak barrels) are high, and during transportation and storage. Among them, wooden wine barrels are easily collided to create gaps, which cause air to infiltrate and cause microbial contamination or affect the flavor of beer. In addition, due to the large amount of carbon dioxide bubbles generated during the fermentation of beer, it is similar to carbonated beverages. In order to maintain the bubble feeling of beer, it is necessary to use a container with high pressure resistance to maintain the concentration of carbon dioxide in the beer. Therefore, in general, retail beer is often made of a glass bottle or an aluminum can which is easy to sterilize and has high airtightness as a container to extend The taste period of beer.

However, in recent years, the concept of environmental protection and resource reuse has been gradually emphasized. If there is a large demand for storage capacity for self-brewing or party gathering, disposable aluminum cans or glass bottles with small capacity are not applicable and will be produced. There are too many beer bottles to be discarded. Therefore, in terms of storing a large amount of beer, the large-capacity stainless steel beer barrel has the advantages of high pressure resistance, easy cleaning, high mechanical strength, and difficulty in breeding bacteria, making it the primary choice for a large number of beer storage containers. In addition, in addition to the carbon dioxide bubbles in the beer, the fine foam on the surface of the beer is also one of the important sources of beer. Therefore, it is more suitable to use a pressurizable valve member than the faucet valve member. In the process of taking out, the beer barrel can be pressurized by connecting a gas cylinder (usually carbon dioxide gas), so that the taken beer can generate fine foam due to the high-pressure gas, thereby adding the taste of the beer, the valve member It is the beer picker adapter.

Compared with the general faucet valve, the structure of the beer picker adapter is more complicated. Generally, a combination of a ball valve, a gas tight valve, an inner spring, an outer spring, a main body casing and a pipe fitting is required to provide a complete a beer hopper adapter for a gas passage and a liquid passage, and thus, in a prior art, a combination of the above or similarly functional parts is fixed to the first through a screwing of the first component and the second component The beer dipper adapter in the interior space of the assembly and the second component, however, relatively increases the complexity of the parts of the beer dipper adapter, thereby affecting ease of use; further, in another prior art, A beer dipper adapter for fixing the combination of the above-mentioned or similarly functional parts to the inner space of the steel sleeve main body and the restraining piece by using a combination of a steel sleeve main body and a restraining piece, which improves the above-mentioned threaded portion The problem of cleaning.
