Abstract
The utility model relates to a cutting edge surface thermocouple, comprising a temperature sensor which head is fixedly connected with the outer wall of an object pipeline via a cutting edge heat conduction block. The cutting edge surface thermocouple is characterized in that an anti-corrosion cover for resisting the corrosion of harmful airflow is added around the head of the temperature sensor and the anti-corrosion cover is stuffed by thermal insulation sponges. The anti-corrosion cover around the temperature sensor can resist the corrosion of harmful airflow. The thermal insulation sponges stuffed in the anti-corrosion cover can resist the temperature fluctuation of the temperature sensor caused by the airflow in hearth. The front end of the temperature sensor is fixedly connected with an object pipeline via a fixing clamp welded on the pipeline, to avoid the detachment between the temperature sensor and the pipeline under thermal expansion and cold shrinkage, to protect the temperature sensor. The middle part of the temperature sensor is made as an expansion ring capable of telescoping freely, therefore, when the temperature in the hearth changes, the temperature sensor can telescope freely.
Description
Technical field
The utility model relates to a kind of thermopair, especially a kind of thermopair that is used for chemical plant.
Background technology
In chemical plant, especially in the refining catalytic hydrogenation plant, temperature in the stove is up to 600～800 ℃, containing sulfuretted hydrogen, sulphuric dioxide etc. in the burner hearth medium is corrosive and acid element, the very fast meeting under air-flow and action of high temperature of these elements is corroded the temperature sensor of thermopair or carbonization, thereby temperature sensor is damaged, general operating period Only Six Months to ten two months.
Summary of the invention
The utility model is high temperature resistant, the etch-proof technical matters that will solve the thermopair that is used for chemical plant, and a kind of blade surface thermopair is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of blade surface thermopair, comprise temperature sensor, the temperature sensor head is fixedlyed connected with the tested pipeline outer wall by the blade heat transfer block, be characterized in: the temperature sensor head is placed outward and is added the anticorrosion cover that can prevent harmful air-flow corrosion, fills heat-preservation cotton in anticorrosion cover.
The temperature sensor front end is fixedlyed connected with tested pipeline by the fixedly card that is welded on the pipeline; The temperature sensor middle part is made into the slack loop of a retractable.
The beneficial effects of the utility model are: add anticorrosion cover in the temperature sensor periphery, can prevent harmful air-flow corrosion.In anticorrosion cover, fill heat-preservation cotton, can prevent that air-flow produces temperature fluctuation to temperature sensor in the burner hearth; The temperature sensor front end is fixedlyed connected with tested pipeline by the fixedly card that is welded on the pipeline, and can prevent expands with heat and contract with cold causes that temperature sensor and pipeline break away from and the damage temperature sensor; Temperature sensor middle part is made into the slack loop of a retractable, and when in the burner hearth during temperature variation, temperature sensor produces breathing, retractable.
