【発明の名称】ガス弁安全装置
Document Type and Number:
Japanese Patent JP2003503654
Kind Code:
A
Abstract:
A safety device for shutting off a gas valve at the detection of a gas leak has an add-on adaptor device having a first knob mounted over an existing gas knob and affixed thereto; a spindle coupled to the first knob, capable of rotating the fist knob, and the gas valve knob, between an open position and a closed position. A second knob is rotatably mounted substantially perpendicular to the spindle, and is provided with firm cantilever which is extended to provide a firm support along side the gas valve knob so as to cause rotation of the gas valve knob when the second knob is rotated in one direction. A spinning is attached to the second knob and is in a wound state when the second knob is parallel to the first knob when the first knob is in the open position, and in an unwound state when the first knob is in the closed position. A bracket is capable of being springably forced into a groove on the second knob when the second knob is aligned substantially parallel to the open position to keep it from rotating. A solenoid retracts the bracket away from the groove so the spring can rotate the second knob into the closed position. A fixing means fixes the add-on adapter device and holds the adapter in place on the existing gas valve knob. A gas leak detector detects the leaks and produces a signal to energize the solenoid and activate the device.
