Description
Technical field
The utility model relates to a kind of temperature instrumentation, especially a kind of single branch multipoint thermocouple.
Background technique
Multipoint thermocouple is usually to be made of more armoured thermocouples and flange, terminal box etc., is suitable for oil-refining chemical mistake
Biggish multiple spot can be set in the inside thermometric of the equipment such as various reactors, holding vessel, synthetic tower in journey, some conventional equipments
The interface of thermocouple is made into DN80 and bigger flange-interface for installing multipoint thermocouple, more interface also can be set
For installing thermocouple；And some special equipment include some experimental rigs because the reasons in structure of equipment can not be arranged compared with
Bigbore interface and more interface, therefore inside can only carry out thermometric with the thermocouple of list Zhi Duodian, further need exist for
Consider the problems such as flexible, pressure-resistant.
Traditional multipoint thermocouple is mostly more armoured thermocouple compositions, and measurement points are inconvenient to install when more, and need
Want biggish bore；Or the single branch multipoint thermocouple being relatively large in diameter, structure are one compared with directly wearing several armourings in large steel pipe
The form of thermocouple, this structural flexibility is poor, and cannot be high pressure resistant.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of single branch multipoint thermocouples, have solved existing multiple spot
Thermocouple, it has not been convenient to install, need larger caliber or flexible poor, cannot be high pressure resistant the disadvantages of, the utility model has diameter
It is excellent that small (lesser diameter can also do more measurement points), flexibility can meet go for a stroll installation, pressure-resistant anti-leak, antivibration etc. of scene
Point.
The utility model can be resolved by the following technical programs:
A kind of single branch multipoint thermocouple of the utility model, including it is outer armour pipe, reinforced pipe, Drain Resistance pullover, compensating wire, more
The thin armoured thermocouple of root or more thermo wires, insulation fillers, described more thin armoured thermocouple or more thermo wires are together with described exhausted
Edge filler is placed in the outer armour pipe the outer armour pipe after drawing and heat treatment together and is inserted in the reinforced pipe and the resistance
Pullover, the reinforcement tube head welded seal are leaked, tail end and the Drain Resistance pullover weld, described more thin armoured thermocouple or more
Thermo wires stretches out from Drain Resistance pullover one end and connects the compensating wire.
As a preferred embodiment, card sets of screws or cutting ferrule flange are installed outside the reinforced pipe.
As a preferred embodiment, described more thin armoured thermocouple passes through an encapsulating pullover respectively and the compensating wire connects
It connects.
As a preferred embodiment, more thin armoured thermocouple soldering in the Drain Resistance pullover.
As a preferred embodiment, more thermo wires in the Drain Resistance pullover connect the compensating wire and fill high pressure resistant close
Sealing.
As a preferred embodiment, the insulation filler is magnesia or aluminium oxide.
The beneficial effects of the utility model are:
1. more than thin armoured thermocouple (or more thermo wires) is put together with insulation filler (such as magnesia, aluminium oxide)
Enter in outer armour pipe, be heat-treated according to different Graduation Numbers using different temperatures after cold-drawn machine is drawn into the outer diameter of needs,
Advantage is compared directly with more thin armoured thermocouples are worn in armouring, fills insulant and the armour pipe after drawing thermocouple has
The advantages that pressure resistance, flexibility, antivibration, smaller diameter.
2. more thin armoured thermocouple soldering in Drain Resistance pullover, medium can effectively prevent after outer armour tracheal rupture from insulation
It is oozed out in filler and causes to leak outside.
3. outer armour pipe and reinforced pipe weld, wherein the active force of card sets of screws is acted directly on reinforced pipe, without right
It is armoured to cause to be squeezed and deformed.
