Title:
RESET DEVICE FOR OVERFLOW PREVENTING VALVE
Document Type and Number:
Japanese Patent JP3089442
Kind Code:
B2
Abstract:
PURPOSE: To simplify a reset device for a built-in overflow preventing valve, in a linear type gas plug.
CONSTITUTION: The main valve of a gas plug forms a linear movement type and an annular body 40 moved in the same direction by means of the main valve is arranged upper stream from a plug holding part 20 in which the main valve is contained. An annular protrusion part 25 is formed in a position concentric to an annular body 40, and an actuator 51 for an over-outflow preventing valve 5 is protruded in the annular protrusion part. A reset lever 4 deformed in a resilient deformation state such that a central part is resiliently deformed from an initial set state to the downstream side through movement of the annular body 40 is arranged in a state that it is positioned at a boundary part between the annular protrusion part 25 and the annular body 40 and on the diameter line thereof. This constitution resets the excessive outflow preventing valve during closing operation of a main valve 1 and sets the valve to a non-reset state during opening operation.
