Abstract
The utility model discloses an armored multi-point thermocouple, which is characterized in that a plurality of thermocouples arranged at the temperature measuring end in sequence are combined into a bundle; and a metal protecting tube with one end closed is formed through drawing and sleeved outside the armored multi-point thermocouple. Due to the adoption of the independent single armored thermocouple inside the armored multi-point thermocouple, the use temperature of the armored multi-point thermocouple can be below 800 DEG C; the phenomena of combined way and body contact, and the like can not be caused during the processing or the use process; and the temperature measuring effect also can not be influenced when water leakage or air leakage occurs outside the protecting tube.
Description
Technical field:
The utility model relates generally to a kind of thermopair, relates in particular to a kind of armouring multiple spot thermopair that includes a plurality of thermopairs unit.
Background technology:
The principle of thermopair is: with two kinds of different alloy materials, one end melting welding connection, the other end are connected secondary instrument.With melting welding link (being the thermometric end), put into the temperature field.Two different alloy materials will produce small generating positive and negative voltage this moment, the voltage difference that produces in the warm place of different temperatures.Logical secondary instrument carries out signal and amplifies, linearization process, compensation.Show a temperature temperature, thereby reach the purpose of thermometric.Existing domestic generally is to adopt the single-point thermopair to carry out thermometric.Its shortcoming is: in same temperature field, the single-point thermopair can only be surveyed the temperature of a point: even insert the temperature that a few Zhi Dandian thermopairs are measured different warm areas in same temperature field, a few Zhi Dandian thermopairs can not be remained on the same axis.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of high temperature overlength oil well multiple spot thermopair to be provided, and it can measure the temperature of different warm areas simultaneously, and is simple in structure, easy to use.
The utility model is achieved through the following technical solutions:
Armouring multiple spot thermopair is characterized in that a plurality of armoured thermocouples that thermometric end echelon is arranged and becomes a branch of, and its outside is set with the protection metal pipe of the end sealing of drawing moulding.
Described armouring multiple spot thermopair, it is characterized in that: described armoured thermocouple is made up of protection metal pipe, insulating material and thermocouple wire, and described thermocouple wire is positioned at protection metal pipe, is filled with magnesia powder between protection metal pipe and thermocouple wire.
Principle of the present utility model is with many armoured thermocouple cables, is processed into the insulation thermocouple element.According to different points for measuring temperature, select the thermocouple element of different length for use, it is a branch of to tie, before tying, before each root thermocouple element, add and the onesize inserts of thermocouple element, to guarantee the accuracy of each measurement point after carrying out drawing, make each thermocouple element not produce displacement, it is in aggregates to carry out drawing in the gapless stainless steel tube of packing into then.Should select the mould that carries out drawing for use before carrying out drawing, mould can not be too big, and too senior general makes the space between stainless-steel tube, and its whole generation is moved.Mould can not be too little, and too little will when drawing thermocouple element too the extruding makes the thermocouple element distortion, causes thermocouple element to produce also road, body contact phenomenon.Above-mentioned phenomenon appears in a thermopair if having wherein in the whole armouring multiple spot thermopair, and that whole armouring multiple spot thermopair just will be scrapped, and can't repair.With the drawing of multiple spot thermocouple element in aggregates after, carry out technical finesse, be processed to form armouring multiple spot thermopair.Armoured thermocouple is called the inorganics insulation thermocouple in the world again; be by stainless steel protection pipe, magnesium oxide insulating powder, the combination of thermocouple wire material; through the solid integral body of compaction die, have that withstand voltage, antidetonation, flexible, miniaturization, thermal response time are fast, easy for installation, an advantage such as long service life, physical strength are good.
The utility model has the advantages that:
Because inner employing the of the present utility model is that separate single is propped up armoured thermocouple; so its serviceability temperature can arrive below 800 ℃: can not cause in processing or when using and phenomenon such as road body contact; and protection tube leaks or gas leak phenomenon when taking place outside, also can not influence its thermometric effect.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
Armouring multiple spot thermopair; include protection metal pipe 1, insulating material 2,4 thermopair unit 3 are arranged in the described protection metal pipe 1, the degree of depth difference of the thermometric end of thermopair unit 3 at the bottom of the protection metal pipe pipe; protection metal pipe 1 adopts stainless-steel tube drawing moulding, is enclosed within outside the thermopair unit.Described thermopair unit 3 is for being made up of interior protection metal pipe, interior insulating material and thermocouple wire, and described thermocouple wire is positioned at protection metal pipe, magnesium oxide insulating powder in being filled with between interior protection metal pipe and thermocouple wire.
