Abstract
The utility model relates to a thermocouple, thermal resistance connection box. The utility model is characterized in that: a connecting base and a splint are connected by bolts, the lower part of the connecting base is provided with a cylinder which in inserted into the base; a cylinder explosion isolating surface which is provided with explosion clearances, a base, a cavity body, a bolt cover and thread circle are mutually welded to a whole.
Description
Technical field: the utility model relates to automation temperature measurement technology field, belongs to a kind of terminal box that thermal resistance thermocouple flame proof is measured temperature specifically, is applicable to oil, chemical industry, natural gas and inflammable and explosive place.
Background technology: the general at present terminal box that adopts; in the environment of or the gas that is corrosive long slightly in industrial site service time; cause twisting after the corrosion covered; more be unable to bear the infiltration of corrosive liquids; even more important flame proof increases whole terminal box volume, so the terminal box radius of turn is also big, installation and use are very inconvenient; especially terminal box is used aluminium alloy, and connecting protection tube can't weld with argon arc welding.
Summary of the invention: the purpose of this utility model provides a kind of can the use in corrosive atmosphere, can not cause because of the corrosion lid of not opening, and explosion-proof chamber is very little, so the little radius of turn of volume is little, uses very convenient thermocouple, the thermal resistance terminal box that can be used for explosion-proof occasion.
For finishing the technical scheme that above-mentioned purpose is taked: junction block is connected by screw with blade assemblies, junction block is divided into cylinder, cylinder inserts in the base, has a flameproof gap cylinder explosion suppresion surface, base, nut sleeve, cavity, the fillet of screw are welded to each other as a whole, above-mentioned junction block requires to be mounted to single formula, two formulas, triadic type according to different wiring thermal resistance or armoured thermocouple.
Parts of the present utility model are existing universal machine converted products, various sour corrosions of ability and make the needs that any selection material satisfies various industrial environments, the junction block design feature is very flexible, and the little installation of more outstanding employing cylinder flame proof volume is very convenient.
Description of drawings:
Fig. 1 is the utility model structure chart.
Embodiment: according to shown in Figure 1, at existing base 1, steel ball chain 2, silicone rubber O-ring 3, lid 4, plus screw 6, fixed cover 7, the fillet of screw 8, nut sleeve 9, sealing ring 11, threading bolt 10, packing ring 12, cavity 13, blade assemblies 14, junction block 15 screws 16 basically, junction block 15 is connected by screw 16 with blade assemblies 14, junction block 15 is divided into cylinder 17, cylinder 17 inserts in the base 1, cylinder explosion suppresion surface 5 with a flameproof gap meets requirement of explosion proof, base 1, nut sleeve 9, it is the integral body of a terminal box that cavity 13 fillets of screw 8 are welded to each other, above-mentioned junction block 15 can connect the binding post of varying number according to different needs, thereby can satisfy single the formula of installing, two formulas, the armoured thermal resistance of triadic type or the needs of armoured thermocouple.
