Replacement parts for beverage injecting section, replacement parts for beverage injecting section and beverage server, and method for mounting replacement parts for drink outlet

摘要

Problem to be solved: to provide a replacement component for a beverage injecting unit capable of generating bubbles with a simple structure, a combination of an exchange part for a beverage injection unit and a drink server, and a method of attaching an exchange part for a beverage injection unit.The replacement parts for the beverage injection unit include an injection pipe, a first tube communicating with the base end of the injection pipe, and a valve member disposed inside the first tube.The first pipe comprises a valve seat portion capable of contacting the valve member, a first portion disposed in the second direction side of the valve seat portion, and a second portion disposed in the third direction side than the valve seat portion.The valve member comprises a seal portion in contact with the valve seat portion, a first large diameter portion forming a bubble generating beverage flow, a second large diameter portion for receiving the bubble generating beverage flow, and a small diameter portion for connecting the first large diameter portion and the second large diameter portion.When the valve member is at the bubble injection out position, the beverages passing through the space between the outer peripheral surface of the first large diameter portion and the inner peripheral surface of the second portion collide with the second large diameter portion to form bubbles.Diagram
