- the soluble metal 600 is welded at two points between the first lever 700 and the second lever 800, the soluble metal 600 has a strong adhesive force and excellent impact resistance.
- the lever is not eccentric position, it is possible to strongly support the closed membrane 300 on the center line connecting the closed membrane 300 and the height adjustment means. Therefore, since the deformation of the fuse and the like can be prevented, leakage of the closed membrane 300 can be prevented due to the weakening of the support force, and malfunction due to the deformation of the available metal 600 can be prevented.
- the fuse has a structure in which two levers that are firmly coupled to each other by the soluble metal 600 facing each other have an integrated structure, thereby facilitating automatic production of the product.
- the soluble metal 600 is welded so as to be in surface contact with the lever, so that heat transfer to the soluble metal 600 is quick, so that the present invention can be applied not only to a standard reactive sprinkler facility but also to an early reactive sprinkler facility.
