The railway wagon temperature monitoring device comprises a tee joint, a temperature measuring plug is arranged at a third port of the tee joint, the temperature measuring plug comprises a plug body, a through plug body first round hole is formed in the plug body, and a first fusible filling body located on the exhaust port side of the first round hole is arranged in the plug body first round hole; a second fusible filling body located on the air inlet side of the first round hole is arranged in the first round hole of the plug body, and the melting point temperature of the first fusible filling body is equal to or higher than the maximum allowable temperature of the non-metal part of the truck. The melting point temperature of the second fusible filling body is equal to or higher than the sum of the maximum allowable temperature of the truck nonmetal part and the tolerance value of the melting point temperature of the first fusible filling body. The temperature measurement plug has the beneficial effects that the double-melting-point fusible alloy temperature measurement technology is adopted, the same round hole of the temperature measurement plug is filled with the high-melting-point fusible alloy and the low-melting-point fusible alloy in a segmented mode, the leakage problem possibly generated by the temperature measurement plug at the highest permissible temperature of a truck is solved, and safety risks are eliminated.
本申请公开了一种铁路货车温度监测装置,包括三通,三通的第三端口处设有测温堵,测温堵包括堵体,堵体上设有贯通的堵体第一圆孔,堵体第一圆孔内设有位于第一圆孔排气口侧的第一易熔填充体,堵体第一圆孔内设有位于第一圆孔进气口侧的第二易熔填充体,第一易熔填充体的熔点温度等于或高于货车非金属件最高允许温度,第二易熔填充体的熔点温度等于或高于货车非金属件最高允许温度与第一易熔填充体熔点温度上公差值之和。本申请的有益效果:采用双熔点易熔合金测温技术,在测温堵的同一个圆孔内分段填充高、低熔点的两种易熔合金,解决货车最高许可温度下测温堵可能产生的泄漏问题,消除安全风险。
