Abstract:
The present invention relates to a device for controlling the supply of carbon dioxide and, particularly, to a device for controlling the supply of carbon dioxide, wherein, in order to allow real-time detection of a carbon dioxide supply amount and easy control of an appropriate carbon dioxide supply amount which needs to be changed due to internal and external factors, the device comprises: a supply amount detection part comprising a bubble detection pipe which is in the form of a transparent tube and in which a liquid is received and carbon dioxide introduced through the bottom thereof moves upward while taking a bubble form and is discharged through an outlet at the top thereof, and a sensing part which senses the number of bubbles moving along the bubble detection pipe; and a valve assembly comprising a valve housing in which a supply channel is formed so as to communicate with the bottom of the bubble detection pipe, an inlet through which carbon dioxide is introduced into the supply channel, a needle valve which is provided in the supply channel so as to control the amount of carbon dioxide introduced into the bubble detection pipe, and a motor which moves the needle valve in the left-and-right direction.
