description	The utility model discloses a fireproof check valve temperature sensing device which comprises an ejector rod assembly and a temperature sensing element, the ejector rod assembly comprises a bottom rod and an ejector rod which are connected in a rotating mode, a force storage bouncing piece is arranged at the rotating connecting position of the bottom rod and the ejector rod, and the temperature sensing element is arranged on the bottom rod. The temperature sensing element is matched with the free end of the ejector rod, and limiting locking and fusing opening of the ejector rod are achieved. The fireproof check valve temperature sensing device is simple in structure, the installation position is not limited by the valve body structure, applicability and universality are high, and due to the fact that the ejector rod is good in stability, the problem of instability does not exist. According to the fireproof check valve, the purposes of universal design and internal and external double fireproof check are achi
