Abstract

The utility model relates to a thermocouple wire arc-shaped protection tube. A thermocouple wire is sequentially inserted into a first tube body and a second tube body at opening ends; a tangency point of the other ends of a fifth arc side and a sixth arc side is provided with a thermocouple test end; an angle d is formed by the two straight sides, and the angle d is an obtuse angle; a resultant force F to which the test end is subjected to is dispersed to the fifth arc side and the sixth arc side; and the larger the obtuse angle is, the higher the dispersion degree of the resultant force becomes, so that the stress of the test end is further weakened.

Description

A kind of galvanic couple silk arc protection tube

Technical field

The invention relates to a kind of component protection pipe, relates in particular to a kind of galvanic couple silk arc protection tube.

Background technology

In existing technology; galvanic couple silk in thermopair is set up protection tube; but this protection tube is the entire body setting; the diameter that namely passes through does not change; and being usually one arranges separately; when thermopair was tested, the power that derives from test lead will make protection tube produce and rock, and then reduced the serviceable life of thermopair.

The innovation and creation content

The problem that the invention will solve is to provide a kind of galvanic couple silk arc protection tube that weakens the impact of thermocouple assay end power.

For solving the problems of the technologies described above, the technical scheme that the invention is adopted is:

A kind of galvanic couple silk arc protection tube; comprise the first body; the second body; be connected with respectively the first arc limit, the second arc limit at an end of the same side of two bodys; this two arc limit is tangential on the A point; is connected with the 3rd arc limit that arranges of stretching out, the 4th arc limit respectively, the other end on two arc limits is connected with the 5th arc limit of the setting that extends internally, the 6th arc limit respectively, the tangent formation d of the other end angle on the 5th arc limit, the 6th arc limit.

As the restriction of the invention, described d angle is the obtuse angle.

As the restriction of the invention, described the 3rd arc limit, the 4th arc limit are tangential on the A point.

Use the invention to have following beneficial effect:

(1) the galvanic couple silk inserts in body at the openend of the first body, the second body in turn, on the 5th arc limit, the other end points of tangency place on the 6th arc limit arranges the thermocouple assay end, the formation d angle on above-mentioned two arc limits, and this d angle is the obtuse angle, even the F that makes a concerted effort of the power that test lead is subject to reduces.

The setting that all stretches out of (2) the 3rd arc limits, the 4th arc limit, the first arc limit, the second arc limit evagination arrange, and form the first order, the second level stops, further reduces the stressed of test lead.

(3) diameter of pipe diameter and galvanic couple silk is suitable, has effectively improved the constant intensity of galvanic couple silk.

Description of drawings

Fig. 1 is the invention structural representation;

Fig. 2 is the stressed schematic diagram of the invention.

In figure:

1, the first body; 11, the first arc limit; 12, the 3rd arc limit; 13, the 5th arc limit; 2, the second body; 21, the second arc limit; 22, the 4th arc limit; 23, the 6th arc limit.

Embodiment

Referring to Fig. 1, in the invention, comprise the first body 1, the second body 2, be connected with respectively the first arc limit 11 at an end of the same side of two bodys, the second arc limit 21, this two arc limit is tangential on the A point, be connected with the 3rd arc limit 12 that arranges of stretching out, the 4th arc limit 22 respectively, the 3rd arc limit, the 4th arc limit are tangential on the A point, the other end on two arc limits is connected with the 5th arc limit 13 that arranges of extending internally, the 6th arc limit 23 respectively, the tangent formation d of the other end angle on the 5th arc limit, the 6th arc limit, and this d angle is the obtuse angle.

Referring to Fig. 2, because the d angle is the obtuse angle, the stressed F that makes a concerted effort of test lead of the 5th arc limit 13, the 6th arc limit 23 points of tangency is distributed to respectively the 5th arc limit 13, the 6th arc limit 23, and the obtuse angle angle is larger, and the F degree of scatter of making a concerted effort is larger, and then has weakened the stressed of test lead.

Claims (3)

1. galvanic couple silk arc protection tube; comprise the first body (1); the second body (2); it is characterized in that; an end in the same side of two bodys is connected with respectively the first arc limit (11), the second arc limit (21); this two arc limit is tangential on the A point; be connected with the 3rd arc limit (12), the 4th arc limit (22) that arranges that stretch out respectively; the other end on two arc limits is connected with the 5th arc limit (13), the 6th arc limit (23) that arranges that extend internally respectively, the tangent formation d of the other end angle on the 5th arc limit, the 6th arc limit.

2. galvanic couple silk arc protection tube according to claim 1, is characterized in that, described d angle is the obtuse angle.
