In embodiment of the present utility model, described armouring silk comprises heart yearn and stainless steel protection cover, is filled with the magnesium oxide insulant in the described stainless steel protection cover.
In embodiment of the present utility model, the endpiece of described armouring silk is fixedly connected with corrugated tube, and described corrugated tube is sleeved on the temperature detecting resistance lead-in wire of prolongation.
In embodiment of the present utility model, described corrugated tube is weldingly fixed on the endpiece of armouring silk by crossover sub.
In embodiment of the present utility model, described corrugated tube is the equal diameter corrugated tube that stainless steel is made, and has the gap between the inwall of temperature detecting resistance lead-in wire and described corrugated tube.
In embodiment of the present utility model, described fixing device for installing is the cutting ferrule bolt.
In embodiment of the present utility model, described temperature detecting resistance is film platinum resistor or copper resistance.
Armouring of the present utility model protection thermal resistance adopts the armouring silk to prolong protection for the temperature detecting resistance lead-in wire of thermal resistance provides, can be withstand voltage, antidetonation, shock resistance, improved the quality of product, and prolonged the serviceable life of product.The stainless steel protection cover of armouring silk has very strong antifouling property and physical strength; and provide enough bending properties; make this thermal resistance be more suitable for being installed in the industrial environment that environment is abominable, the space is narrow and small; because its strong shock resistance is not fragile, can save the human and material resources cost in the plant maintenance process greatly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation according to the armouring protection thermal resistance of an embodiment of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Figure 1 is the structural representation of protecting thermal resistance 10 according to the armouring of an embodiment of the utility model.As shown in Figure 1, this armouring protection thermal resistance 10 comprises temperature detecting resistance (not shown), protection tube 11, fixing device for installing 12, armouring silk 13, crossover sub 14, corrugated tube 15 and temperature detecting resistance lead-in wire 16.Wherein, temperature detecting resistance is encapsulated in the head of protection tube 11, and the temperature detecting resistance lead-in wire is drawn from this protection tube 11, is transferred in the secondary instrument of rear end with the signal long-distance that thermal resistance is measured.
Fixing device for installing 12 is weldingly fixed on the afterbody of protection tube 11, is used for thermal resistance 10 is installed in Devices to test.Specifically, among the embodiment shown in Figure 1, fixing device for installing 12 is cutting ferrule bolts, is welded on the protection tube 11 according to the placed-depth of thermal resistance, in order to thermal resistance 10 is installed on the equipment according to certain placed-depth.
In addition, as shown in Figure 1, thermal resistance 10 of the present utility model also is provided with armouring silk 13 to provide extensive protection to the temperature detecting resistance lead-in wire, and this armouring silk 13 is weldingly fixed on the tail end of protection tube 11.According to the difference of employed temperature detecting resistance, armouring silk 13 can put the stainless steel protection cover outward by for example three or six roots of sensation heart yearn and constitute, and is filled with the magnesium oxide insulant in it, makes that this armouring silk is 13 withstand voltage, antidetonation, shock resistance.One end of the heart yearn of armouring silk 13 and the temperature detecting resistance lead-in wire electrical connection of drawing from protection tube 11, the other end of heart yearn is electrically connected temperature detecting resistance lead-in wire 16 to realize long Distance Transmission.The stainless steel protection cover of armouring silk 13 has very strong antifouling property and physical strength, and enough bending properties are provided, and makes this thermal resistance be fit to be installed in the occasion that environment is abominable and the space is narrow and small.
