SUCTION TYPE OPERATION VALVE

Japanese Patent JP2015218831

A

PROBLEM TO BE SOLVED: To provide a method of smoothly opening a valve for easy drinking, as in a conventional suction-type operation valve as a piston-type operation mechanism utilizing a Pascal's law of negative pressure with a simple swing valve structure, a valve element is mounted to be opened in a direction opposite to a flow channel direction in drinking with suction force, and a valve element is sucked back even if it is opened, so that a person must sip with a small valve opening, and is hard to drink.SOLUTION: A main-valve valve element 17 is mounted to be opened in a flow channel forward direction, a bell crank-shaped arm 22 is mounted on a suction-valve valve element 18 opened to an opposite side in the longitudinal direction when observed from an inflow side, and the main-valve valve element 17 is connected to a connection rod 21, thus the main-valve valve element 17 is drawn and a main valve is opened when the suction-valve valve element 18 is closed by suction. As in this suction-type operation valve 1, a fluid is pressed out with the main-valve valve element 17 by a fluid pressure while drawing and opening the main-valve valve element 17 by sucking, and the fluid is sucked from a valve opening port, so that the suction-type operation valve 1 capable of smoothly being opened with high response can be provided.
