Abstract
A kind of high-precision thermocouple of flow channel type, including sleeve pipe, measurement core, flange and terminal box, described measurement core is installed on inside pipe casing, described flange is installed on sleeve pipe, described terminal box is installed on cannula tip, described sleeve bottom one end outer wall is provided with multigroup conduit caved inward, and described measurement outer core is exposed to channel floor.The new beneficial effect of the utility model is：The utility model is novel in design, simple in construction, and it is exposed to measure core using segment boundses, it is ensured that measurement medium is fully contacted with measurement core, so as to improve measurement accuracy, while the original defencive function of sleeve pipe can also be played, is killed two birds with one stone, convenient and swift.
Description
Technical field
The utility model is related to instrument processing technique field, and in particular to a kind of high-precision thermocouple of flow channel type.
Background technology
Thermocouple is the temperature element commonly used in temperature measuring instrument, its direct measurement temperature, and temperature signal is changed
Into thermo-electromotive force signal, the temperature of measured medium, the normal pole because of needs of profile of various thermocouples are converted into by electric meter
Differ, but their basic structure is roughly the same, thermocouple is directed to different use environments in actual application
In, different structures can be related to and improved, at this stage, because the thermal inertia of thermocouple makes the indicated value of instrument lag behind by thermometric
The change of degree, when quickly measure, this influence is especially prominent, so should be as straight compared with thin, protection pipe using thermode as possible
The less thermocouple in footpath.During thermometric environmental permission, or even protection pipe can be removed, in use, generally using good heat conductivity
Material, the protection sleeve pipe that tube wall is thin, internal diameter is small, in more accurate temperature survey, using the naked silk thermocouple of unprotect sleeve pipe,
Effect is the most notable, but for now, and the thermocouple of no casing protection is being carried out in use, spoilage is high itself,
It must regularly replace, cause substantial amounts of waste.
Utility model content
Technical problem to be solved in the utility model is that offer is a kind of simple in construction, and accurately flow channel type is high-precision for measurement
Thermocouple.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of high-precision thermocouple of flow channel type, including sleeve pipe, measurement core, flange and terminal box, it is characterised in that：Described survey
Amount core is installed on inside pipe casing, and described flange is installed on sleeve pipe, and described terminal box is installed on cannula tip, described set
Bottom of the tube one end outer wall is provided with multigroup conduit caved inward, and described measurement outer core is exposed to channel floor.
It is thin compared with both ends open in the middle part of described conduit section, the entrance of liquid medium is facilitated while liquid can also be increased
Contact area between medium and measurement core；
The outer wall that described measurement core is located at channel floor is provided with angular raised line, is easy to fully experience medium temperature, soon
It is prompt accurate.
In the middle part of described conduit a filtering batten is installed, it is to avoid introduced contaminants directly adheres to measurement outer core, it is ensured that
The cleanliness factor of core is measured, measurement accuracy is improved.
The utility model is when in use：Measure medium and directly enter internal by conduit, be then directly contacted with measurement core, from
And fundamentally ensure that measurement medium with measuring fully contacting for core.
The new beneficial effect of the utility model is：The utility model is novel in design, simple in construction, is measured using segment boundses
Core is exposed, it is ensured that measurement medium is fully contacted with measurement core, so that measurement accuracy is improved, while it is former to play sleeve pipe
Some defencive functions, kill two birds with one stone, convenient and swift.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1 and Figure 2, the high-precision thermocouple of a kind of flow channel type, including sleeve pipe 1, measurement core 2, flange 3 and terminal box 4,
Measurement core 2 is installed on inside sleeve pipe 1, and flange 3 is installed on sleeve pipe 1, and terminal box 4 is installed on the top of sleeve pipe 1, the bottom one of sleeve pipe 1
End outer wall is provided with multigroup conduit 5 caved inward, and the measurement outer wall of core 2 is exposed to the bottom of conduit 5, after so setting, and measurement is situated between
Upright connect enters internal by conduit 5, is then directly contacted with measurement core 2, so as to fundamentally ensure that measurement medium and measurement
It is thin compared with both ends open in the middle part of the abundant contact of core 2, the section of conduit 5, the entrance of liquid medium is facilitated while liquid can also be increased
Contact area between body medium and measurement core 2, the outer wall that measurement core 2 is located at the bottom of conduit 5 is provided with angular raised line 6, is easy to
Fully experience medium temperature, it is quick precisely, the middle part of conduit 5 is provided with a filtering batten 7, it is to avoid introduced contaminants directly adheres to survey
Measure the outer wall of core 2, it is ensured that the cleanliness factor of measurement core 2, improve measurement accuracy.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
