Abstract
The invention provides a preparation method of a low-pressure-loss rupture membrane and a rupture membrane structure.The preparation method of the low-pressure-loss rupture membrane comprises the steps that a membrane and a cutter serve as matrixes, the cutter is connected to the connecting face of the membrane through a connecting device to prepare the rupture membrane structure, and the connecting face of the membrane is provided with a bonding layer; the membrane and the cutter are both made of metal materials, and the bonding layer is made of metal with the melting point lower than that of the membrane and the cutter; the diaphragm and the cutter are connected in a diffusion welding mode to form a low-pressure-loss rupture membrane structure. Through the preparation method, the stability of connection between the diaphragm and the cutter can be improved, the quality of the cutter is guaranteed, and finally the stability of the opening pressure of the rupture diaphragm and the consistency of the opening shape are guaranteed.
