一种测试采样枪

Testing sampling gun

Abstract

本实用新型涉及一种测试采样枪,将测试用的三根钢管固定在金属片周围,金属片中心设置有一个插入铠装热电偶的小孔,铠装热电偶用于测试排烟温度,金属片可以起到密封测试孔的作用,通过金属片将三根钢管分为左右两侧,左侧钢管通过三根乳胶管连接燃烧效率分析仪,右侧钢管插入到烟道内部,进行烟气抽取。通过采用上述结构,可方便快速的对电厂空气预热器漏风率及电厂锅炉的热效率进行测试。可广泛应用于电厂空气预热器漏风率及电厂锅炉的热效率的测试领域。
The utility model relates to a testing sampling gun. Three steel tubes for testing are fixed around a metal piece, a small hole for inserting a sheathed thermocouple is formed in the center of the metal piece, the sheathed thermocouple is used for testing the exhaust gas temperature, the metal piece can have an action of sealing a testing hole, the three steel tubes are divided into the left side and the right side by the metal piece, the steel tubes on the left side are connected with a combustion efficiency analysis instrument through three latex tubes, and the steel tubes on the right side are inserted into a flue for exhaust gas extraction. With adoption of the structure, the air leakage rate of an air preheater in a power plant and the thermal efficiency of a boiler in the power plant can be conveniently and rapidly tested, and the testing sampling gun can be widely applied to the testing field of the air leakage rate of the air preheater in the power plant and the thermal efficiency of the boiler in the power plant.
