Abstract

The utility model relates to a pyrolysis furnace boiler tube surface heat galvanic couple, including pyrolysis furnace boiler tube, boss, lower pipe joint, going up pipe joint, elbow, thermocouple core, the movable screw of third, the boss vertical welding is on the pyrolysis furnace boiler tube, and the heat conduction piece welds at the pyrolysis furnace boiler tube in the middle of lieing in the boss hole, the thermocouple core is connected to the heat conduction piece, the thermocouple core is connected with the terminal box after passing down pipe joint, elbow and going up the pipe joint, and is fixed through pressure disk and the locking of the movable screw of third between lower pipe joint and the boss. The utility model discloses a boss is used for whole fixed product, welds the heat conduction piece that pastes on the boiler tube in the boss, and the thermocouple core is worn in the heat conduction piece for the temperature measurement is more accurate, going up the pipe joint and passing through 90 degrees installations of corner joint one -tenth with lower pipe joint, the terminal box is in last pipe joint top, and convenient scene is installed and is worked a telephone switchboard when safeguarding, the movable screw of three departments can be changed alone when the dismouting by the thermocouple, twists and also can not rotate protection tube and terminal box when moving the screw, lets the terminal box direction be in the top all the time.

Description

Cracking furnace tube surface thermocouple
Technical field
The utility model relates to a kind of surface thermocouple, especially a kind of thermopair being applicable to Ethylene Cracking Furnace Tubes surface temperature measurement.
Background technology
In Ethylene Cracking Furnace Tubes, medium temperature is higher, generally at about 850 DEG C, needs to measure its medium temperature and furnace tube temperature according to technological requirement, and the surface temperature of boiler tube is all generally adopt thermopair to carry out thermometric.
Cracking furnace tube surface temperature is higher, and the installation of TC needs to consider the problems such as the temperature in the precision of thermopair, convenient for installation and maintenance, the space of installing and terminal box.Existing surface thermocouple all cannot well solve above-mentioned all problems, causes thermopair precision or installation and maintenance convenience all not to reach the actual demand of client.Therefore a kind of surface thermocouple that can solve the problem is badly in need of.
Summary of the invention
The problems such as technical problem to be solved in the utility model is: provide a kind of cracking furnace tube surface thermocouple, not high to solve existing thermocouple measurement precision, and installation and maintenance are convenient not.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cracking furnace tube surface thermocouple, comprise cracking furnace tube, boss, lower pipe joint, upper pipe joint, elbow, thermocouple core, the 3rd movable screw, described boss vertical welding is on cracking furnace tube, heat-conducting block is positioned at and is welded on cracking furnace tube in the middle of boss endoporus, described heat-conducting block connects thermocouple core, described thermocouple core is connected with terminal box with after upper pipe joint through lower pipe joint, elbow, is fixed between described lower pipe joint and boss by platen and the 3rd movable screw locking.
Described lower pipe joint is connected by elbow with between upper pipe joint, and is fixed by the first movable screw locking between lower pipe joint and elbow, is fixed between upper pipe joint and elbow by the second movable screw locking.Described platen front end is connected with interference fit between boss endoporus.Described elbow is 90 degree of elbows.
The beneficial effects of the utility model are:
1, boss is used for fixing whole product, and be welded with the heat-conducting block be attached on boiler tube in boss, thermocouple core is through in heat-conducting block, makes thermometric more accurate;
2, upper pipe joint and lower pipe joint connect into 90 degree of installations by elbow, and terminal box is in above pipe joint, wiring when facilitating on-site installation and maintenance.
3, the three movable screws in place can be changed separately when dismounting by thermopair, also can not rotate protection tube and terminal box when turning screw, allow terminal box direction be in top all the time.
Accompanying drawing explanation
Fig. 1 is the structural representation of cracking furnace tube surface thermocouple of the present utility model.
Embodiment
As shown in Figure 1, a kind of cracking furnace tube surface thermocouple, comprises cracking furnace tube 1, boss 2, lower pipe joint 3, the movable screw 4 of elbow 5, first, upper pipe joint 7, terminal box 8, heat-conducting block 9, thermocouple core 10, the movable screw 6 of platen 11, second, the 3rd movable screw 12.
Boss 2 vertical welding is on cracking furnace tube 1, heat-conducting block 9 is positioned at and is welded on cracking furnace tube 1 in the middle of boss 2 endoporus, thermocouple core 10 is contained in pipe joint 7, upper pipe joint 7 lower end is connected with the second movable screw 6, thermocouple core 10 is through bending and upper pipe joint 7 one-tenth 90 degree of directions after elbow, thermocouple core 10 penetrates in lower pipe joint 3 to heat-conducting block 9 again, and tightens the first movable screw 4 and the 3rd movable screw 12.Be locked by platen 11 and the 3rd movable screw 12 between lower pipe joint 3 and boss 2.
Be connected by elbow 5 between lower pipe joint 3 with upper pipe joint 7, and be locked by the first movable screw 4 between lower pipe joint 3 and elbow 5, be locked by the second movable screw 6 between upper pipe joint 7 and elbow 5.Elbow 5 is 90 degree of elbows.Between platen 11 front end with boss 2 endoporus, interference fit is connected.Namely boss 2 internal diameter is less than platen 11 external diameter.
