Abstract
The invention discloses a gas connector. The gas connector is provided with ten pipelines. The gas connector comprises an arrow upper part, a ground part and a disengaging mechanism. The arrow upper part is fixedly connected with arrows through bolts and provided with a groove. The ground part is connected with the arrow upper part in a butt joint mode. The disengaging mechanism comprises a gas disengaging cavity and a pull rod. The elasticity of a small spring is overcome by supplying gas to the gas disengaging cavity or forcefully pulling the pull rod so that the ground part can be separated from the arrow upper part. The ground part and the arrow upper part are locked tightly through a plurality of steel balls, the locking force is large, and super-high pressure sealing can be achieved. The ground part disengages from the arrow upper part through the force of a large spring, and the impact force is small. The gas connector has two disengaging methods, remote control is adopted in the two disengaging methods, and the process is safe and reliable.
