Abstract
Antidetonation temperature measuring device is including temperature element, temperature element includes: nonrust steel pipe, copper pipe, pt resistance, magnesium oxide, overcoat copper pipe behind pt resistance and the lead welding, the intraductal packing magnesia of copper, the copper outside of tubes overlaps nonrust steel pipe again, then contracts behind the reducing, encapsulates at the tip again. The utility model has the advantages of: owing to changed the temperature element structure, increased the copper pipe, therefore the improvement greatly of its shock resistance, life also improves greatly. The utility model discloses through actual long -term the use, its stability is 0.30 DEG C deviation (10000 hours), does fatigue strength satisfy 10Hz 55Hz, life reaches more than 1 year.
Description
Technical field
This utility model is related to antidetonation temperature measuring equipment, especially relates to temperature survey dress used on nuclear power station
Put.
Background technology
Existing 1500 revs/min of rotating speed of main pump of pressurized water reactor nuclear power plants operating, frequency：25 hertz, vibration amplitude is big, and it is adopted
Traditional structure armoured thermal resistance sensor is used as temperature measuring tool.It is carried out with armouring resistance lead with Pt100 resistive elements
Welding；The Pt100 component resistances lead packages being welded are packaged using one section of stainless steel sleeve；The stainless steel sleeve the inside of encapsulation
Without any implant, coordinated with stainless steel sleeve gap against Pt100 resistive elements, and using common cutting ferrule spiral shell
Bolt is fixed installation, therefore does not adapt to the needs of main pump of pressurized water reactor nuclear power plants operation.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned not enough of prior art and provide a kind of antidetonation temperature
Degree measurement apparatus so as to which anti-seismic performance is good.
The technical scheme in the invention for solving the above technical problem is：
Antidetonation temperature measuring equipment, including temperature element；Temperature element includes：Stainless steel tube, copper pipe, Pt resistance, oxidation
Overcoat copper pipe after magnesium, the Pt resistance and lead welding, filling magnesia powder, covers again stainless steel tube, then in copper pipe outside copper pipe
After contracting reducing, then it is packaged in end.
Preferably, cutting ferrule bolt assembly is also fixed outside the temperature element, the cutting ferrule bolt assembly includes card cap, card
Pearl, snap ring, compression spring, cutting ferrule nut, fix bar；Temperature element passes through fix bar, and compression spring loading is put outside fix bar
It is in cutting ferrule nut and spacing by cutting ferrule nut top, then fix bar is stuck on nut by snap ring, fix bar upper end is again by card cap
Temperature element is fixed by card bead.
Preferably, above-mentioned Pt resistance is Pt100 resistive elements.
Compared with prior art, the utility model has the advantage of：Due to changing temperature element structure, copper is increased
Manage, therefore its shockproof properties is greatly improved, service life is also greatly improved.
The actual life-time service of this utility model Jing, its stability is deviation ± 0.30 DEG C（10000 hours）, shock strength is full
Sufficient 10Hz-55Hz, service life was up to more than 1 year.
Description of the drawings
Fig. 1 is the structural representation of this utility model embodiment antidetonation temperature measuring equipment.
Fig. 2 is the A-A profiles of Fig. 1.
Fig. 3 is the exploded view of this utility model embodiment cutting ferrule bolt assembly.
Specific embodiment
Below in conjunction with the accompanying drawings, embodiment is further illustrated to this utility model.
As shown in Fig. 1, antidetonation temperature measuring equipment, including rustless steel rosette 6, temperature element and cutting ferrule bolt assembly
5。
As shown in Fig. 2 temperature element includes：Rustless steel 1, copper pipe 2, Pt100 resistive elements 3, magnesium oxide 4, the Pt100
Overcoat copper pipe 2 after resistive element 3 and lead welding, filling magnesium oxide in copper pipe 2（MgO) powder 4, copper pipe 2 is outer to cover again stainless steel tube
1, then after contracting reducing, then it is packaged in end.
Cutting ferrule bolt assembly 5 is also fixed outside above-mentioned temperature element, by cutting ferrule bolt assembly 5 by antidetonation temperature measuring equipment
It is fixed to field of employment.
As shown in figure 3, above-mentioned cutting ferrule bolt assembly includes card cap 51, card bead 52, snap ring 53, compression spring 54, cutting ferrule spiral shell
Female 56, fix bar 57.
Temperature element passes through fix bar 57, fix bar 57 to put compression spring 54 outward and be fitted in cutting ferrule nut 56 and by cutting ferrule
The top of nut 56 is spacing, then fix bar 57 is stuck on nut by snap ring 53, and the upper end of fix bar 57 passes through card bead by card cap 51 again
52 fix temperature element.
Due to increased fix bar 57 and compression spring 54, therefore antidetonation temperature measuring equipment is fixed to into field of employment
When, compression spring 54 can slow down impulse force, play more preferable antihunt action.
Also sealed by sealing ring 55 between above-mentioned fix bar 57 and cutting ferrule nut 56.
