A kind of high temperature resisting thermocouple of explosion-proof, relate to survey instrument and manufacture field, comprise sleeve pipe, measure core, flange, terminal block and terminal box composition, described flange is arranged on the middle part of sleeve pipe, described terminal block is arranged on the top of sleeve pipe, described set of terminal box is outside terminal block, described measurement core is arranged on inside pipe casing, described measurement core and the junction of sleeve pipe, the junction of sleeve pipe and flange all adopts laser bonding, the upper end of described sleeve pipe is coated with the high temperature resistant circle of a circle, described high temperature resistant circle and the junction of flange also adopt laser bonding.The beneficial effects of the utility model are: the utility model is novel in design, structure is simple, pass through laser bonding, ensure that the closure of sleeve pipe, avoid liquid and enter inside pipe casing, thus cause blast, the setting of high temperature resistant circle simultaneously, ensure that the thermotolerance of galvanic couple, improve integral firmness energy, more durable in use.
Description
Technical field
The utility model relates to survey instrument and manufactures field, is specifically related to a kind of high temperature resisting thermocouple of explosion-proof.
Background technology
Thermopair is temperature element conventional in temperature measuring instrument, its direct measuring tempeature, and temperature signal is converted to thermopower signal, is converted to the temperature of measured medium by electric meter (secondary instrument).The profile of various thermopair is often far from it because of needs, but their basic structure is roughly the same, usually by thermode, the major part compositions such as insulation sleeve protection tube and terminal box, usually and Displaying Meter, recorder and electronic controller support the use, thermopair its be mainly used in the measurement that liquid materials carries out temperature, common thermopair its be produced on sounding rod and all can be equipped with the parts such as flange and terminal block, all can there is corresponding contact in the sounding rod of therefore galvanic couple, therefore when galvanic couple is when measuring, liquid may enter because the sealing of contact is strong and measure dry inside, thus cause galvanic couple impaired, even also can cause blast, dangerous large.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, the high temperature resisting thermocouple of the explosion-proof of use safety.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of high temperature resisting thermocouple of explosion-proof, comprise sleeve pipe, measure core, flange, terminal block and terminal box composition, it is characterized in that: described flange is arranged on the middle part of sleeve pipe, described terminal block is arranged on the top of sleeve pipe, described set of terminal box is outside terminal block, described measurement core is arranged on inside pipe casing, described measurement core and the junction of sleeve pipe, the junction of sleeve pipe and flange all adopts laser bonding, the upper end of described sleeve pipe is coated with the high temperature resistant circle of a circle, and described high temperature resistant circle and the junction of flange also adopt laser bonding.
Described high temperature resistant circle adopts cupric oxide to make, and intensity is high, and cost is low.
The beneficial effects of the utility model are: the utility model is novel in design, structure is simple, pass through laser bonding, ensure that the closure of sleeve pipe, avoid liquid and enter inside pipe casing, thus cause blast, the setting of high temperature resistant circle simultaneously, ensure that the thermotolerance of galvanic couple, improve integral firmness energy, more durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of high temperature resisting thermocouple of explosion-proof, comprise sleeve pipe 1, measure core 2, flange 3, terminal block 4 and terminal box 5 form, flange 3 is arranged on the middle part of sleeve pipe 1, terminal block 4 is arranged on the top of sleeve pipe 1, terminal box 5 is arranged on outside terminal block 4, measure core 2 and be arranged on sleeve pipe 1 inside, measure the junction of core 2 and sleeve pipe 1, sleeve pipe 1 all adopts laser bonding with the junction of flange 3, the upper end of sleeve pipe 1 is coated with the high temperature resistant circle 6 of a circle, high temperature resistant circle 6 also adopts laser bonding with the junction of flange 3, after arranging like this, pass through laser bonding, ensure that the closure of sleeve pipe 1, avoid liquid and enter sleeve pipe 1 inside, thus cause blast, the setting of high temperature resistant circle 6 simultaneously, ensure that the thermotolerance of galvanic couple, improve integral firmness energy, high temperature resistant circle 6 adopts cupric oxide to make, intensity is high, cost is low.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
