Liquid Delivery System and Liquid-Flowpath Regulating Device

摘要

Easily serviced and hygienically maintained liquid supply system. A liquid storage vessel switching device switches between vessels to supply liquid uninterruptedly. Provided in a first connection tube is a liquid cutoff device, including a loop section, for switching the system between allowing/cutting-off supplying of liquid to a dispenser through the first connection tube. Utilizing the liquid cutoff device eliminates, along the first connection tube, intervening conventional valves having structural components that come in direct contact with the supplied liquid, and on which sponges or other cleaning elements might get caught. The inner wall of the first connection tube may thus be cleaned readily with a sponge or the like. Beverages such as beer thus can easily be kept hygienically and served.

主权项

1. A liquid-delivery system comprising:
a liquid-storage vessel storing a liquid; a liquid external-delivery device for delivering the liquid externally; and a liquid-flowpath regulating device including
a delivery conduit connecting said liquid-storage vessel and said liquid external-delivery device and forming a delivery flowpath from said liquid-storage vessel to said liquid external-delivery device, said delivery conduit including, in a predetermined location therein, a branch part,a discharge conduit branching from said branch part and forming a discharge flowpath from said liquid-storage vessel,a delivery-conduit opening/closing means arranged in a predetermined location along said delivery conduit, said delivery-conduit opening/closing means for switching into a delivery-enabled state in which the liquid can be delivered via said delivery conduit, and into a delivery-disabled state being a state in which via said delivery conduit delivery of the liquid cannot take place, anda discharge-conduit opening/closing means arranged in a predetermined location along said discharge conduit, said discharge-conduit opening/closing means for switching into a delivery-enabled state in which the liquid can be delivered via said discharge conduit member, and into a delivery-disabled state being a state in which via said discharge conduit delivery of the liquid cannot take place, said liquid-flowpath regulating device therein for regulating the delivery flowpath and the discharge flowpath, and accordingly being configured so as to put said delivery-conduit opening/closing means and said discharge-conduit opening/closing means into the delivery-disabled state when delivery of the liquid from the liquid-storage vessel concludes, and thereafter put said discharge-conduit opening/closing means into the delivery-enabled state.
