The utility model discloses has the vibration resistance that has improved measuring junction " butt fusion point ", connector good contact under vibration and filthy ambient condition has been ensured to the agility of overhauing has been improved, the advantages such as unfavorable operating condition of cold junction high temperature insulation line have been improved.
Description
Technical field
The utility model relates to temperature monitoring field, especially relates to a kind of temperature probe adapting to high temperature, vibration and filthy environment.
Background technology
Utilize " thermoelectric effect " of the metal material of two kinds of heterogeneities, " thermopair " made has been widely used in temperature monitoring field.
The end of two kinds of metal thermo wires, after welding, disposal of stability, forms the measuring junction of " thermopair "." sealing-off " or " fracture " is easily there is and lost efficacy in measuring junction fusion point under high temperature and vibration environment.In addition, the cold junction of " thermopair " adopts terminal or welded-connecting type connector to be connected with secondary instrument usually.Under vibration and filthy environment, terminal or welded-connecting type connector easily cause loose contact or " sealing-off " to lose efficacy, and are also not easy to Quick overhaul.
Utility model content
The purpose of this utility model is: for prior art Problems existing, provides a kind of temperature probe adapting to high temperature, vibration and filthy environment, solves measuring junction " fusion point " antivibration problem; Solve the high temperature insulation line of cold junction and the reliable connection of external extended line (or compensating wire) and Quick overhaul problem; Solve the intensity of protection tube and sex chromosome mosaicism easy for installation; Improve the unfavorable condition of work of cold junction high temperature insulation line.
The purpose of this utility model is achieved through the following technical solutions:
Adapt to a temperature probe for high temperature, vibration and filthy environment, comprise measuring junction, device body and cold junction, it is characterized in that, device is as bending structure, and cold junction is provided with plug connector, the high temperature insulation line of cold junction and plug connector cold weld.
As further technical scheme, between two thermodes of measuring junction, be provided with two fusion points.
As further technical scheme, whole device body is made up of the measuring junction connecting portion be connected successively, bend and cold junction connecting portion, and measuring junction connecting portion and cold junction connecting portion form the angle of 150 °.
As further technical scheme, the connected mode between the external extended line of plug connector and cold junction or compensating wire is cold weld.
As further technical scheme, plug connector is the connector of IP65 degree of protection, the gold-plated contact pin of crimp type.
As further technical scheme, cold junction is provided with the flexible protective pipe of high temperature insulation line.
As further technical scheme, flexible protective pipe is formed by stainless steel wire coiling.
Compared with prior art, the utility model has the following advantages:
1, adopt " two point welding " technique (being namely provided with two fusion points), improve the vibration resistance of measuring junction " fusion point ";
2, the connector of high-protection level (IP65), the gold-plated contact pin of crimp type is adopted, the high temperature insulation line of cold junction and external extended line (or compensating wire) carry out cold weld with " the gold-plated contact pin " of connector respectively, ensure that connector is in vibration and good contacting under filthy environment condition, and improve the agility of maintenance;
3, adopt the flexible protective pipe of stainless steel wire coiling cold junction high temperature insulation line, improve the convenience of protection tube intensity and installation;
4, adopt 150 ° of device body bending structures, add the distance of cold junction high temperature insulation line and periphery thermal source, improve the unfavorable condition of work of cold junction high temperature insulation line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
The utility model provides a kind of temperature probe adapting to high temperature, vibration and filthy environment, and as shown in Figure 1, it forms primarily of measuring junction 1, device body 2 and cold junction 3.
Device body 2 is bending structure, be made up of the measuring junction connecting portion 201 be connected successively, bend 202 and cold junction connecting portion 203, measuring junction connecting portion 201 and cold junction connecting portion 203 form the angle of 150 °, thus add the distance of cold junction high temperature insulation line and periphery thermal source, improve the unfavorable condition of work of cold junction high temperature insulation line.
Cold junction 3 is provided with plug connector 4, high temperature insulation line 5 and plug connector 4 cold weld of cold junction 3.If cold junction is provided with external extended line or compensating wire 7, then the external extended line of cold junction or compensating wire 7 equally also adopt the mode of cold weld to be connected with plug connector 4.Which ensure that connector is in vibration and good contacting under filthy environment condition, and improve the agility of maintenance.Plug connector 4 adopts the connector of high-protection level (IP65), the gold-plated contact pin of crimp type.
Be provided with two fusion points 6 between two thermodes of measuring junction 1, namely two thermodes end welding once, in the place apart from a bit of distance of this fusion point, welding once, forms two fusion points again.Adopt this " two point welding " technique, substantially increase the vibration resistance of measuring junction " fusion point ".
The flexible protective pipe 8 of high temperature insulation line 5 is provided with at cold junction 3.The present embodiment adopts the flexible protective pipe of stainless steel wire coiling cold junction high temperature insulation line, improves the convenience of protection tube intensity and installation.
The utility model obtains checking in row's temperature monitoring of high-power medium speed engine.During row's temperature detector is surveyed, on point position place engine exhaust branch pipe and house steward, heat radiation is large, vibration is violent, filthy serious, former conventional temperature sensor lost efficacy and took place frequently.Adopt the temperature probe after the technical program, reliability significantly improves, the life-span extends greatly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
