℃。
Preferably, the fusing point of the higher melting-point fusible metal column is 120-140 DEG C.
By adopting the above-described technical solution, the utility model has the advantages that：
Fusible plug does not have to integral replacing, simple in structure only with the inner body part for replacing meltable cock body, and connects jail
Gu not influencing using effect；
The part that inner body is connect with outer barrel can be made extremely frivolous, and materials are few, but intensity does not have much influences, whole
For body, waste of material is less, greatly reduces use cost, and replaces rapid.
Fusible plug is using conventional axial length, and the active force of the axial restraint of fusible metal is big, and compressive effect is good, will not
Deviate from cock body, and the fusible metal column in fusible plug cock body interstitial hole before overheating protection fusing point 10-30 DEG C i.e. initially enter it is molten
Melt state, when reaching overheating protection fusing point, the fusible metal column in both ends of the hole rapidly enters molten condition, plays overheat in due course
The effect of protection, the fusible metal column in interstitial hole are in molten condition, and heat-conducting effect is more preferable, further promotes in both ends of the hole
Fusible metal column melting.
