The temperature measuring core body is connected with the wiring box, the lower end of the wiring box is sleeved with the protection tube, the temperature measuring core body is arranged at the lower end, in the protection tube, of the wiring box, the outer wall of the temperature measuring core body in the protection tube is sleeved with a heat conduction casing tube, thermal transmission protrusions are arranged on the side wall of the heat conduction casing tube, and the thermal transmission protrusions are embedded on the wall of the protection tube. The quick-response multi-point thermal coupler is simple in structure and scientific and reasonable in design, the temperature measuring core body is firmly connected with the protection tube, the response time is shortened, and powerful guarantee is provided for precise temperature control.
Description
Technical field
The invention belongs to area of thermocouples, especially a kind of multipoint thermocouple of response fast.
Background technology
In the technology controlling and process step of the industries such as petrochemical complex, various catalytic reactors, the temperature control of hydrogenation reactor and synthesis reactor needs the participation of thermopair, thermopair primary structure comprises terminal box, protection tube and thermometric core body, thermometric core body is sleeved in protection tube, although this kind of structure can be measured the temperature in reactor, but because the response meeting that has certain interval to change for reactor temperature between thermometric core body and protection tube is slack-off, have certain delay for accurate control temperature of reaction, be unfavorable for the control of reactor temperature, even if having some thermometric core bodys can fit with protection tube part by bending, because reactor inner fluid produces vibration, cause thermometric core body to contact with protection tube unstable, affect accurate temperature controlling effect, part is fitted the thermometric core body response time generally more than 10 seconds.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of multipoint thermocouple of response be fast provided, this thermocouple structure is simple, design science rationally, thermometric core body is connected firmly with protection tube, response time shortening, for accurate temperature controlling provides powerful guarantee.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of multipoint thermocouple of response fast; this thermopair comprises terminal box, protection tube and thermometric core body; thermometric core body connects terminal box; protection tube is sleeved on terminal box lower end; thermometric core body is arranged on the terminal box lower end in protection tube; its thermometric core body outer wall in protection tube is set with a thermal conducting sleeve, and this thermal conducting sleeve sidewall is made heat and transmitted projection, and this heat transmission projection is embedded on protection tube wall.
And described heat transmission projection is embedded on protection tube wall and flushes integral with protection tube outer wall.
And described heat transmission projection is embedded on protection tube wall and leans out protection tube outer wall.
And, described protection tube outer wall suit flange.
And the thermometric core body in described protection tube is fixedly mounted with by clamping screw.
Advantage of the present invention and beneficial effect are:
This is response multipoint thermocouple fast; this thermopair comprises terminal box, protection tube and thermometric core body; thermometric core body connects terminal box; protection tube is sleeved on terminal box lower end; thermometric core body is arranged on the terminal box lower end in protection tube; its thermometric core body outer wall in protection tube is set with a thermal conducting sleeve; this thermal conducting sleeve sidewall is made heat and is transmitted projection; this heat transmission projection is embedded on protection tube wall; the present invention is simple in structure, design science is reasonable, thermometric core body and protection tube are connected firmly; response time shortens, for accurate temperature controlling provides powerful guarantee.
Heat of the present invention is transmitted projection and is embedded on protection tube wall and flushes integral with protection tube outer wall; heat on thermal conducting sleeve is transmitted protruding direct detection reactor temperature; quick and precisely demonstrate reactor temperature and by System Implementation control by thermometric core body; logical heat transfer projection is surveyed; thermopair just can complete temperature-responsive within the time that is less than 8 seconds; faster more than 2 seconds than the thermopair of common contact-type; be conducive to accurately react rapidly and control inside reactor temperature, make the reaction in reactor more steady.
