a wine spear

Abstract

The invention provides a beer keg valve, and belongs to the technical field of beer drinking equipment. The problem that a flexible bag is likely to be damaged in the using process of an existing beer keg valve is solved. The beer keg valve comprises a valve body and a beer discharging pipe. A valve element capable of controlling the beer discharging pipe to be on and off is arranged inside the beer discharging pipe. The beer discharging pipe comprises an upper pipe body and a lower pipe body. The lower pipe body is fixedly connected to the lower end of the valve body. The upper pipe body is arranged at the upper end of the lower pipe body in sliding and sleeving modes. A first reset spring capable of making the upper pipe body abut against the inner wall of the valve body is arranged between the lower pipe body and the upper pipe body. A sealing element is arranged between the lower pipe body and the upper pipe body. The valve body is provided with a plurality of guide beads used for guiding the upper pipe body in the circumferential direction. By the adoption of the beer keg valve, the phenomenon that the flexible bag moves during beer discharging operation can be avoided, and thus the flexible bag cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of wine drinking equipment and relates to a wine spear. Background technique [0002] A wine barrel is a tool for holding wine. Generally, a wine spear is arranged at the barrel mouth of the wine barrel, and the wine spear cooperates with the dispenser to realize pressing out the wine in the wine barrel. At present, the wine barrels commonly used in the market are all metal wine barrels. Metal wine barrels are expensive and troublesome to clean. Generally, merchants do not have special equipment for cleaning metal wine barrels. Therefore, after the wine in the barrel is used up, , It is necessary to transport the empty wine barrels to the factory for cleaning, which increases the cost of transportation back and forth. Moreover, when this kind of wine barrel is pressing out the wine, the gas is directly filled into the inside of the wine barrel, and the pressure of the gas is applied to the surface of the wi...

Problems solved by technology

At present, the wine barrels commonly used in the market are all metal wine barrels. Metal wine barrels are expensive and troublesome to clean. Generally, merchants do not have special equipment for cleaning metal wine barrels. Therefore, after the wine in the barrel is used up, , it is necessary to transport the empty wine barrels to the factory for cleaning, which increases the cost of transportation back and forth

Moreover, when this kind of wine barrel is pressing out the wine, the gas is directly filled into the inside of the wine barrel, and the pressure of the gas is applied to the surface of the wine to press out the wine. In this way, the gas and the wine need to be in contact, which is easy Cause beer to decline in wine quality due to oxidation and bacteria invasion

[0003] Further, as the patent document (GB1549733A) discloses a structure of a wine spear, the wine spear includes a valve body and a wine outlet pipe, the two are fixedly connected, and the valve body is used to be fixedly connected to the barrel body. It is necessary to press down the wine tube, and then press gas into the barrel, and the gas will pressurize the liquid surface of the wine to press out the wine. If a flexible bag is added to the structure, and the flexible bag is used to hold the wine, then the flexible bag can only The gas can squeeze the flexible bag when it is fixed on the wine outlet pipe, and the flexible bag will move with it when the wine outlet pipe moves downward. Damaged flexible bag

[0004] There is also a valve for a pressure vessel for distributing a liquid (such as beer) under the pressure of a gas (such as CO 2 ) as disclosed in the Chinese patent application (application number: 98809101.1), which contains a valve seat that limits the valve axis, An elastic material valve ring arranged coaxially with the valve seat and having a reinforcing ring preferably coaxially embedded, a gas passage formed between the valve ring seat and the valve ring when the valve is opened, and a gas passage formed between the valve ring seat and the valve ring when the valve is opened At the same time, the liquid channel formed through the center hole of the valve ring also needs to press down the liquid pipe when the liquid is discharged, and if a flexible bag is added to the structure, and the flexible bag is used to hold wine, then the flexible bag can only be fixed. On the riser, the gas is able to squeeze the flexible bag, which also causes the flexible bag to move with the riser

[0005] Another example is a container sealing device disclosed in Chinese patent application (application number: 95191522.3). Liquids such as dry beer are stored in the container under gas pressure such as CO2, and the combined gas-liquid valve is threaded on the neck ring of the container. On the top, the sealing ring is placed between the parallel opposite ring surfaces of the valve and the neck ring, and the cylindrical protrusion protrudes from the ring surface of the valve to the ring surface of the neck ring. This structure also includes the wine outlet pipe, which needs to be pressed down when the wine needs to be discharged. For the wine outlet pipe, if a flexible bag is added to the structure to hold wine, then the flexible bag can only be fixed on the wine outlet pipe so that the gas can squeeze the flexible bag, and the wine outlet pipe is flexible when it moves down. The bag will move along with it. The flexible bag contains alcohol and is heavy. Such a long-term reciprocating movement of the flexible bag will easily cause damage to the flexible bag.
