Smoke monitoring device for fire damper

The utility model provides a smoke monitoring device for a fire damper, relates to the field of fire exhaust valves, and aims to solve the problems that a smoke leakage monitoring device is not arranged at a joint of a blade of an existing fire exhaust valve, and when smoke leakage occurs at a contact position, a worker cannot make feedback in time. Comprising a valve body, an end wind shielding support, a blade shaft, blades and a smoke monitoring mechanism, the end wind shielding support is arranged in the valve body, the blade shaft is arranged in the valve body, the blades are installed on the blade shaft, and the smoke monitoring mechanism is installed on the blades. Once smoke leaks, a worker can make remedy in time, and leakproofness between adjacent blades is fed back in real time through expansion of the balloon. 本实用新型提供一种用于防火阀的烟雾监测装置，其涉及排火阀领域，旨在解决现有排火阀叶片的接缝处未设置烟雾泄漏监测装置，接触处出现烟雾泄漏时，工作人员不能及时作出反馈的问题。包括有阀体、端挡风支架、叶片轴、叶片以及烟雾监测机构，所述端挡风支架设置在阀体中，所述叶片轴设置在阀体中，所述叶片安装在叶片轴上，所述烟雾监测机构安装设置在叶片上，通过烟雾监测机构的设置，实时监测叶片接缝处的烟
