Beer keg valve

Abstract

The invention provides a beer keg valve and belongs to the technical field of beer drinking equipment. The problems that a great effort is needed and an operation hand feeling is poor when an existing beer keg valve is used for draining beer are solved. The beer keg valve comprises a valve body, a beer drainage pipe and an annular base. The side wall of the upper end of the beer drainage pipe is provided with a beer outlet. The beer drainage pipe is fixedly connected with the interior of the valve body. The upper end of the beer drainage pipe is sleeved with the base in a sliding mode. The base is located in the valve body. A reset spring capable of driving the base to abut against the inner wall of the valve body is arranged between the valve body and the base. The annular sealing ring is arranged on the inner wall of the base in the circumferential direction and abuts against the outer wall of the beer drainage pipe. The sealing ring is located below the beer outlet. A guide structure capable of keeping the base stably sliding up and down is arranged between the valve body and the base. According to the beer keg valve, beer drainage is more convenient, and airtightness of beer can be ensured.

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...

AI Technical Summary

Problems solved by technology

The wine spear includes a seat body, which is slidably sleeved on the wine outlet pipe. When the distributor presses the sealing ring and moves downward, the gas enters the liner from the passage, thereby pressing out the wine. However, the seat body There is a cylindrical sealing layer on the inner wall, and the inner wall of the sealing layer is attached to the outer wall of the wine outlet tube. The friction between the two is relatively large, resulting in laborious operation of the wine outlet and poor operating feel.
