Operating method of the present utility model is: 1. permanent joint partly is installed on the miniature hydrogen storing tank, method be with self-enclosed joint B and set screw nut matches and an end insert in the top cover of miniature hydrogen storing tank, seal with set screw nut locking and by the seal ring that is embedded in self-enclosed joint B end face in jar, the interior valve inside of self-enclosed joint B this moment is in self-enclosed state.2. partly be connected to movable joint on the tracheae, method is that tracheae is inserted in the self-enclosed joint A, screw then match with self-enclosed joint A and the tracheae locknut, tracheae is fixed on the movable joint part, the valve inside in this moment self-enclosed joint A is in self-enclosed state.3. during gas transmission, movable joint part and permanent joint are partly docked, the butt end of self-enclosed joint A is inserted in the link and by two seal rings that are embedded in self-enclosed joint A cylindrical and is sealed, the locknut of movable joint part and permanent joint link partly are by being threaded, movable joint part and permanent joint are partly fused, two valve inside directions that are positioned at self-enclosed joint A and self-enclosed joint B this moment on the contrary and the top offset, when continuing to screw locknut, because two valve inside tops offset and cause axial displacement in it, make two valve insides all be in opening state, hydrogen in the miniature hydrogen storing tank relies on pressure reduction outwards to carry, and this moment, four seal rings can be guaranteed the isolated of the gas distribution channel and the external world; Unscrew locknut after gas transmission is finished, the interior axle of two valve insides resets, and recovers self-enclosed state, movable joint part and permanent joint partly can be separated.
The two self-sealing joints of a kind of above-mentioned miniature hydrogen storing tank, it is characterized in that: it is the standard piece of steel or stainless steel that two valve insides all adopt GB5V1, withstand voltage 4Mpa, material.
The two self-sealing joints of a kind of above-mentioned miniature hydrogen storing tank, it is characterized in that: except that valve inside, all metalworks all adopt brass or stainless steel manufacturing.
The two self-sealing joints of a kind of above-mentioned miniature hydrogen storing tank, it is characterized in that: four seal rings all adopt General Purpose Rubber.
The utility model has the advantages that: simple in structure, easy manufacturing, good airproof performance, safe and reliable, easy to use, flexibly and fast and cost lower, be specially adapted to use as rapid pipe joint in the gas injection operation of miniature hydrogen storing tank.
