Description
Technical field
The present invention relates to a kind of thermopair (resistance), relate in particular to a kind of dismounting of being convenient between protective casing and the flange, thus the novelty that reduces cost sweating heat galvanic couple (resistance) not.
Background technology
In essential industry production runes such as oil, chemical industry, metallurgy, electric power, measuring temperature with thermopair (resistance) is the most general ways and means of contact type temperature sensor.Especially be in the chemical process of raw material with oil, coal, not only use generally, and consumption be very big.Particularly process high sulfur-bearing, high-acid crude oil, because the continuous variation of chemical analysis, thermometric requires more and more higher, and the thermometric environment is more and more abominable, and contact type temperature sensor thermopair (resistance) is proposed requirements at the higher level under the safe prerequisite of ensuring the quality of products.Protective casing is thermopair (resistance) key in serviceable life; at present; thermopair (resistance) protective casing material; international, the domestic austenitic stainless steel of always continuing to use; the connected mode of protective casing and flange, therefore international, the domestic welding manner that generally adopts exists the erosion corrosion in protective casing hot junction and the problems such as acid gas burn into hydrogen corrosion cracking in flange root weld zone; can not satisfy the actual production requirement substantially, it is very big that quantity is changed in the cycle maintenance.Owing to all adopted flange and protective casing welded structure mutually originally; in order to guarantee welding quality; have to the employing of requirement flange and protective casing with a kind of material; the flange materials are twices of protective casing materials; in order to satisfy the needs of thermometric environment; the cost price of these materials is all very high, particularly adopts resistant to elevated temperatures nickel-base material.And change quantity big mainly be protective casing, in the time will changing protective casing,, flange and protective casing can only be changed together owing to flange and protective casing can't be taken apart, this just must waste materials is the flange material of protective casing twice.Therefore, original thermopair (resistance) structure has not only increased the manufacturing production cost, has more wasted ample resources.
Summary of the invention
The present invention mainly solves flange and protective casing employing welding connection structure in original thermopair (resistance), expensive material use amount is big, and in the time will changing protective casing, flange and protective casing can't be taken apart, can only change together, not only increase and make production cost, the technical matters of more wasting ample resources; Not sweating heat galvanic couple (resistance) of a kind of novelty is provided; make that the dismounting between flange and the protective casing is very convenient; owing to do not adopt welding manner; flange can adopt the material that is different from protective casing; can adopt lower-cost material, when reduction manufacturing production cost, and needs is greatly changed protective casing; need not to change flange, saved ample resources.
Another purpose of the present invention provides not sweating heat galvanic couple (resistance) of a kind of novelty; got rid of the seam organization that causes because of welding technology and heat-affected zone crystal grain is thick or inhomogeneous, because of the problems of welded quality such as unrelieved stress of the higher generation of weld hardness; solved the problem that ftractures because of the not acidproof gas corrosion of welding region, the corrosion of not anti-hydrogen; both improved rigidity, the intensity of protective casing, and made heatproof, corrosion resistant performance again also along with raising.
The present invention has solved the sealing problem after flange and protective casing adopt welding connection structure not again; Not sweating heat galvanic couple (resistance) of a kind of novelty is provided, has multiple leak stopping function, under the special condition of severe of operating mode; even production period protective casing cracking or fracture; measured medium can be toward external leakage yet, reaches the effect of not only antidetonation but also leak stopping, the security performance height.
The present invention has also solved the difficulty that the upper-lower position of temperature-sensing element can't be regulated in original thermopair (resistance), the termination of temperature-sensing element be difficult to protective casing in be close at the bottom of the blind hole, have the thermal response hysteresis phenomenon, influence the technical matters of measuring accuracy; Not sweating heat galvanic couple (resistance) of a kind of novelty is provided, and the upper-lower position that it can regulate temperature-sensing element easily is close at the bottom of the interior blind hole of protective casing the termination of temperature-sensing element, reduces the thermal response hysteresis phenomenon, improves measuring accuracy, and has improved anti-seismic performance again.
