QUICK COUPLING CONNECTOR WITH HIDDEN THERMAL CUTOFF FOR VALVE OF L.P. GAS CYLINDER OR SIMILAR FUEL SOURCES.

摘要

The present invention refers to a coupling system which consists in a nipple, a device against overflow, a rotating nut located around the nipple and a thermal cutoff arranged around the nipple between the nut and the nipple recess. The thermal cutoff is made of a heat-sensitive material. The thermal cutoff is designed to be deformed in case of high temperature, causing the check valve arranged within the valve of the cylinder to cut the flow of the fluid. There is no need to replace the nut once the thermal cutoff is activated, thus only replacing the thermal cutoff. The present invention reduces the misalignment, at the maximum extent, between the nut and the nipple due to the large contact area between the nipple and the nut. The present invention is advantageous in that it protects the thermal cutoff from sun rays. The present invention removes the problems associated to previously designed connectors.
