<p>PURPOSE: To make a control valve for opening a discharge cock work as a duct for the carbonated, liquid and to enable other mechanical elements work on a valve without penetrating the same into the storage tank by controlling the flow of the carbonated liquid into a container from a storage tank by placing the container under pressure and by placing the filled container under atomospheric pressure. CONSTITUTION: Because liquid to be discharged is preferably carbonated liquid, it is absolutely necessary to maintain pressure higher than saturation pressure in a container 8 while the liquid is being filled. Therefore, it is desirable to maintain constant air tightness between the spout 9 of the container 8 and the bottom face 6 of a main body 2. The periphery of an opening part 7 formed in a face is designed as much as possible to match the form of the spout 9 of the container 8. In the recess 3 of the main body 2, a valve seat 10 for a valve 11 is positioned, and the means 12 for controlling the flow of the carbonated liquid contained in the storage tank 13 works on the seat valve.</p> |
