Technical field
The present invention relates to thermopair technical field, relate in particular to a kind of bent thermopair.
Background technology
In the essential industry production runes such as oil, chemical industry, metallurgy, electric power, with thermocouple measuring temperature, it is most widely used mode, its principal feature is that measurement range is wide, performance is more stable, simultaneously simple in structure, dynamic response is good, can long-distance transmissions electric signal, be convenient to realize automatic control and centralized control.Thermopair has can be crooked, high pressure resistant, thermal response time is fast and the fastening advantage such as durable, and they can be in direct various production runes of measurement, from liquid, steam and gas medium within the scope of 0-1000 ℃ and the temperature of solid surface.In prior art, thermopair is straight and cannot bend often, and the tool for mounting of thermopair is had higher requirements, and brings the inconvenience of installing, and need to improve.
Summary of the invention
In order to solve the technical matters existing in background technology, the present invention proposes a kind of bent thermopair, realized the improvement to thermocouple structure, it is easy to bending, to installation environment strong adaptability.
A kind of bent thermopair that the present invention proposes, comprise temperature-sensing element, protective casing, terminal box and coupling assembling, protective casing, coupling assembling, terminal box connect successively, coupling assembling comprises n pliability adapter and n+1 support column, pliability is taken over two ends and is had cutting ferrule, above-mentioned cutting ferrule is provided with external thread, support column inwall is provided with the internal thread coordinating with above-mentioned external thread, and protective casing is provided with the external thread with above-mentioned screw-internal thread fit near coupling assembling one end and terminal box near coupling assembling one end; In coupling assembling, be provided with spiral fashion compensating wire, compensating wire one end is connected with temperature-sensing element and the other end is connected with terminal box, and temperature-sensing element stretches in the blind hole of protective casing away from compensating wire one end; Adjacent pliability is taken over and is connected by support column, and coupling assembling two ends pliability is taken over and all by support column, is connected respectively with protective casing, terminal box, and the Length Ratio that support column and pliability are taken over is 1:(1-2), wherein, n >=1 and n are natural number.
Preferably, the value of n is 2.
Preferably, the Length Ratio that support column and pliability are taken over is 2:3.
In the present invention, the temperature-sensing element being arranged in protective casing is mainly used for thermometric space to carry out temperature survey, and coupling assembling is connected protective casing with terminal box, and the compensating wire being arranged in coupling assembling is communicated with temperature-sensing element with terminal box, coupling assembling adopts pliability to take over and support column combines, wherein pliability is taken over and can be provided required flexibility for coupling assembling, coupling assembling can be bent, thereby make thermopair there is bent characteristic, support column is coordinated adjacent pliability is taken over and linked together by the internal thread of inwall and the external thread of cutting ferrule, the Length Ratio of taking over due to support column and pliability is 1:(1-2), thereby make support column to provide required rigidity for coupling assembling, thereby prevent that coupling assembling is too soft and bring the inconvenience in use, therefore, by pliability, take over and the cooperatively interacting of support column, make coupling assembling there is good flexibility under the necessary hard condition of maintenance, thereby being had, thermopair is easy to bending, to the adaptable advantage of installation environment.
